Release Notes - These notes are for ncurses 6.0, released August 8, 2015. + These notes are for ncurses 6.1, released January 27, 2018. This release is designed to be source-compatible with ncurses 5.0 - through 5.9; providing a new application binary interface (ABI). - Although the source can still be configured to support the ncurses 5 - ABI, the intent of the release is to provide extensions which are - generally useful, but binary-incompatible with ncurses 5: - * Extend the cchar_t structure to allow more than 16 colors to be - encoded. - * Modify the encoding of mouse state to make room for a 5th mouse - button. That allows one to use ncurses with a wheel mouse with - xterm or similar X terminal emulators. - - There are, of course, numerous other improvements, including - * fixes made based on the Clang and Coverity static analyzers. - * memory leak fixes using Valgrind - - The release notes mention some bug-fixes, but are focused on new - features and improvements to existing features log since ncurses 5.9 + through 6.0; providing extensions to the application binary interface + (ABI). Although the source can still be configured to support the + ncurses 5 ABI, the intent of the release is to provide extensions to + the ncurses 6 ABI: + * improve integration of tput and tset + * provide support for extended numeric capabilities. + + There are, of course, numerous other improvements, listed in this + announcement. + + The release notes also mention some bug-fixes, but are focused on new + features and improvements to existing features since ncurses 6.0 release. - While the intent of the release is to provide a new stable ABI, there - are other development activities which are summarized below. - * The original release plan, e.g., for "5.10" was to improve the - MinGW port. Ultimately that was completed (wide-character support, - mouse, etc), but was deferred to focus on termcap support and - performance issues. Also, pinpointing the problems with Console2 - took a while. - * A review of termcap compatibility in 2011 led to several minor - fixes in the library and improvements to utilities. To do this - properly, a review of the various extent termcap implementations - was needed. - The [11]termcap library checker (tctest) (not part of ncurses) was - one result. A followup review of performance using - [12]ncurses-examples in 2014 led to additional improvements. - * Output buffering provided a further, but worthwhile distraction. A - bug report in 2012 regarding the use of signal handlers in - ncurses) pointed out [13]a problem with the use of unsafe - functions for handling SIGTSTP. Other signals could be addressed - with workarounds; repairing SIGTSTP required a different approach. - The solution required changing internal behavior of the library: - how it handles output buffering. - Now ncurses buffers its own output, independently of the standard - output. A few applications relied upon the library's direct reuse - of the standard output buffering; however that is unspecified - behavior and has never been a recommended practice. Identifying - these applications as well as refining the change to permit - low-level applications to work consistently took time. - * Since the introduction of the experimental support for 256 colors - early in [14]2005 (released in [15]ncurses 5.5), there has been - increased user interest. Almost all packagers continue providing - the ncurses ABI 5 which cannot support 256 colors. - * Symbol versioning, or the lack of it in ncurses, is the main - reason why packagers would be reluctant to add a new ncurses ABI. - This release provides the new ABI along with script-generated - lists of versioned symbols which can be used for both ABI 5 and 6 - (with distinct names to keep the two separate). This took time to - development, as reported in [16]Symbol versioning in ncurses. - Library improvements - Output buffering - - X/Open curses provides more than one initialization function: - * [17]initscr (the simplest) accepts no parameters. - * [18]newterm accepts parameters for the stream input and output - * [19]setupterm (the low-level function) accepts a parameter for the - file descriptor of the output. - - They are documented in X/Open as if initscr calls newterm using stdout - for output stream, and in turn newterm calls setupterm using - fileno(stdout) for the file descriptor. As long as an implementation - acts as if it does this, it conforms. In practice, implementations do - what is implied. This creates a problem: the low-level setupterm - function's file descriptor is unbuffered, while newterm implies - buffered output. X/Open Curses says that all output is done through - the file descriptor, and does not say how the output stream is - actually used. - - Initially, ncurses used the file descriptor (obtained from the output - stream passed to newterm) for changing the terminal modes, and relied - upon the output parameter of newterm for buffered output. Later (to - avoid using unsafe buffered I/O in signal handlers), ncurses was - modified to use the file descriptor (unbuffered output) when cleaning - up on receipt of a signal. Otherwise (when not handling a signal), it - continued to use the buffered output. - - That approach worked reasonably well and as a side effect, using the - same buffered output as an application might use for printf meant that - no flushing was needed when switching between normal- and - screen-modes. - - There were a couple of problems: - * to get good performance, curses (not only ncurses, but SVr4 curses - in general) set an output buffer using setbuf or similar function. - There is no standard (or portable) way to turn that output buffer - off, and revert to line-buffering. The [20]NCURSES_NO_SETBUF - environment variable did make it optional. - * to handle SIGTSTP (the "stop" signal), ncurses relied upon unsafe - functions. That is, due to the complexity of the feature, it - relied upon reusing existing functions which should not have been - called via the signal handler. - - Conveniently, solving the second problem (by making ncurses do its own - output buffering) also fixed the first one. But there were special - cases to resolve: [21]low-level functions such as mvcur, putp, vidattr - explicitly use the standard output. Those functions were reused - internally, and required modification to distinguish whether they were - used by the high-level or low-level interfaces. - - Finally, there may still be a few programs which should be modified to - improve their portability, e.g., adding an - -fflush(stdout); - - when switching from "[22]shell" mode to "[23]program" (curses) mode. - Those are fairly rare because most programmers have learned not to mix - printf and [24]printw. - - Symbol versioning - - This release introduces symbol-versioning to ncurses because without - it, the change of ABI would be less successful. A lengthy discussion - will be presented in [25]Symbol versioning in ncurses. These notes - summarize what has changed, and what can be done with the new release. - - Symbol-versioning allows the developers of a library to mark each - public symbol (both data and functions) with an identifier denoting - the library name and the version for which it was built. By doing - this, users of the library have a way to help ensure that applications - do not accidentally load an incompatible library. In addition, private - symbols can be hidden entirely. - - This release provides sample files for the four principal - configurations of ncurses libraries: ncurses, ncursesw, ncursest and - ncursestw. Each sample is given in two forms: - - ".map" - These list all public symbols, together with version names. - - ".sym" - These list all public symbols, without version names. - - The sample files are generated by scripts which take into account a - few special cases such as [26]tack to omit many of the ncurses private - symbols (beginning with "_nc_"). Here are counts of globals versus - locals: - - Config Symbols Globals Locals "_nc_" - ncurses 976 796 180 332 - ncursesw 1089 905 184 343 - ncursest 979 804 175 358 - ncursestw 1098 914 184 372 - - Although only four sample configurations are presented, each is formed - by merging symbols from several combinations of configure-script - options, taking into account advice from downstream packagers. Because - they are formed by merging, the sample files may list a symbol which - is not in a given package. That is expected. The samples have been - tested and are working with systems (such as Fedora, FreeBSD and - Debian) which fully support this feature. There are other systems - which do not support the feature, and a few (such as Solaris) which - provide incomplete support. - - The version-naming convention used allows these sample files to build - distinct libraries for ABI 5 and 6. Version names consist of - * configuration name, e.g., "NCURSESW" for the wide-character - libraries - * ABI version (if not 5) - * library name for two special cases which have the same interface - across configurations: "TINFO" and "TIC" - * release version - * patch date (for the release version) - - For example, running nm -D on the libraries in the ncurses6 test - package shows these symbol-versions: - -0000000000000000 A NCURSES6_TIC_5.0.19991023 -0000000000000000 A NCURSES6_TIC_5.1.20000708 -0000000000000000 A NCURSES6_TIC_5.5.20051010 -0000000000000000 A NCURSES6_TIC_5.7.20081102 -0000000000000000 A NCURSES6_TIC_5.9.20150530 -0000000000000000 A NCURSES6_TINFO_5.0.19991023 -0000000000000000 A NCURSES6_TINFO_5.1.20000708 -0000000000000000 A NCURSES6_TINFO_5.2.20001021 -0000000000000000 A NCURSES6_TINFO_5.3.20021019 -0000000000000000 A NCURSES6_TINFO_5.4.20040208 -0000000000000000 A NCURSES6_TINFO_5.5.20051010 -0000000000000000 A NCURSES6_TINFO_5.6.20061217 -0000000000000000 A NCURSES6_TINFO_5.7.20081102 -0000000000000000 A NCURSES6_TINFO_5.8.20110226 -0000000000000000 A NCURSES6_TINFO_5.9.20150530 -0000000000000000 A NCURSESW6_5.1.20000708 -0000000000000000 A NCURSESW6_5.3.20021019 -0000000000000000 A NCURSESW6_5.4.20040208 -0000000000000000 A NCURSESW6_5.5.20051010 -0000000000000000 A NCURSESW6_5.6.20061217 -0000000000000000 A NCURSESW6_5.7.20081102 -0000000000000000 A NCURSESW6_5.8.20110226 -0000000000000000 A NCURSESW6_5.9.20150530 - - As a special case, this release (which makes the final change for ABI - 5) is marked with release version 5.9 and patch date 20150530. - - Miscellaneous - - The new release has several improvements for performance and building. - For instance: - * several files in ncurses- and progs-directories were modified to - allow const data used in internal tables to be put by the linker - into the readonly text segment. - * various improvements were made to building the Ada95 binding, both - in simplifying the generated files as well as improving the way it - uses gnatmake - - There are also new features in the libraries: - * added [27]use_tioctl function - * added [28]wgetdelay to retrieve _delay member of WINDOW if it - happens to be opaque, e.g., in the pthread configuration. - * added [29]A_ITALIC extension. - * added form library extension [30]O_DYNAMIC_JUSTIFY option which - can be used to override the different treatment of justification - for static versus dynamic fields . - * rewrote [31]putwin and [32]getwin, making an extended version - which is capable of reading screen-dumps between the wide/normal - ncurses configurations. These are text files, except for a magic - code at the beginning: - -0 string \210\210 Screen-dump (ncurses) - - * several changes to mouse support include: - + added decoder for xterm SGR 1006 mouse mode. - + added experimental support for "%u" format to terminfo. - + improved behavior of wheel-mice for xterm protocol: noting - that there are only button-presses for buttons "4" and "5", - so there is no need to wait to combine events into - double-clicks . - - There are a few new configure options dealing with library - customization: - * add "--enable-ext-putwin" configure option to turn on the extended - putwin/getwin. By default, this is enabled for ABI 6 and disabled - with ABI 5. - * add "--enable-string-hacks" option to control whether strlcat and - strlcpy may be used. Because ncurses already does the requisite - buffer-limit checks, this feature is mainly of interest to quiet - compiler-warnings on a few systems. - * add configure option "--with-tparm-arg" to allow [33]tparm's - parameters to be something more likely to be the same size as a - pointer, e.g., intptr_t (again, the default is set for ABI 6). + New features + + The improved integration of tput and tset made only small changes to + the libraries. However, supporting extended numeric capabilities + required a few changes: + * The TERMINAL structure in is now opaque. Doing that + allowed making the structure larger, to hold the extended numeric + data. + A few applications required changes during development of + ncurses 6.1 because those applications misused the members of that + structure, e.g., directly modifying it rather than using + [13]def_prog_mode. + * Having made TERMINAL opaque (and because none of the library + functions use anything except a pointer to TERMINAL), it was + possible to increase the size of the structure, adding to the end. + Existing applications which were linked to the ncurses 6.0 + high-level (ncurses, ncursesw) and low-level (tinfo, tinfo) + libraries should not require re-linking since the binary interface + did not change, nor did the structure offsets with TERMINAL + change. + A few applications use the inner TERMTYPE structure's offsets to + refer to terminfo capabilities within that structure. Again, those + do not require modification because their offsets within TERMINAL + did not change. + * When configured for wide-characters, i.e., "ncursesw" the TERMINAL + structure is extended. + The new data in TERMINAL holds the same information as TERMTYPE, + but with larger numbers ("int" versus "short"). It is named + TERMTYPE2. + The library uses this structure internally in preference to + TERMTYPE, referring to TERMTYPE only to initialize it for + applications that use the capabilities defined in + * When configured for 8-bit (narrow) characters, the TERMTYPE2 + structure is not used. + * The updated application binary interface is 6.1.20171230 (used for + new [14]versioned symbols), although the interface changes were + developed several months previously. + + The motivation for making this extension came from noticing that + [15]termcap applications could (though not [16]realistically) use + larger numbers than would fit in 16-bits, and the fact that the number + of color pairs for a 256-color xterm could not be expressed in + terminfo (i.e., 32767 versus 65536). Also, a few terminals support + direct-colors, which could use the extension. + + Generally speaking, applications that use internal details of a + library are unsupported. There was exactly one exception for ncurses: + the tack program used the internal details of TERMINAL, because it + provides an ncurses-specific feature for interactively modifying a + terminfo description and writing the updated description to a + text-file. It was possible to not only separate tack from these + [17]internal details of ncurses, but to generalize it so that the + program works with Unix curses (omitting the ncurses-specific + feature). That was released as [18]tack 1.08 in July 2017. + + While making changes to tack to eliminate its dependency upon ncurses + internals, the publicly-visible details of those internals were + reviewed, and some symbols were moved to private header files, while + others were marked explicitly as ncurses internals. Future releases of + ncurses may eliminate some of those symbols (such as those used by + tack 1.07) because they are neither part of the API or the ABI. + + Using the TERMTYPE2 extended numeric capabilities, it is possible to + support both color pair values and color values past 32767. Taking + compatibility into account, developers readily understand that neither + function signatures nor structure offsets change. Also, existing + functions have to operate with the extended numbers. Most of that work + is internal to the library. For the external interfaces, a hybrid + approach was used: + * X/Open Curses defined function prototypes such as wattr_set with + an unused parameter, for "future" use. After 25 years, the future + is here: ncurses uses the parameter to augment color pair values + as described in the [19]manual page. + * Other functions such as those defining color pairs did not have a + corresponding reserved parameter. For those, ncurses defines + extended versions such as init_extended_pair (versus init_pair), + init_extended_color (versus init_color). + + Additionally, to improve performance other changes (and extensions) + are provided in this release: + * Several new functions simplify management of large sets of color + pairs: reset_color_pairs, alloc_pair, find_pair and free_pair. + * New "RGB" extension capability for direct-color support is used to + improve performance of color_content. + * The internal colorpair_t is now a struct, eliminating an internal + 8-bit limit on colors + * Allocation for SCREEN's color-pair table starts small, grows on + demand up to the limit given in the terminal description. + * setcchar and getcchar now treat a negative color-pair as an error. + + Other improvements + + These are new or revised features: + * modify c++/etip.h.in to accommodate deprecation of throw and + throws in c++17 + * add new function unfocus_current_field + * add option to preserve leading whitespace in form fields + * add a macro for is_linetouched and adjust the function's return + value to make it possible for most applications to check for an + error-return. + * add build-time utility report_offsets to help show when the + various configurations of tinfo library are compatible or not. + + These were done to limit or ultimately deprecate features: + * drop two symbols obsoleted in 2004: _nc_check_termtype, and + _nc_resolve_uses + * move _nc_tracebits, _tracedump and _tracemouse to curses.priv.h, + since they are not part of the suggested ABI6. + * mark some structs in form/menu/panel libraries as potentially + opaque without modifying API/ABI. + * ifdef'd header-file definition of mouse_trafo with + NCURSES_NOMACROS + * remove initialization-check for calling napms in the term-driver + configuration; none is needed. + * modify trace to avoid overwriting existing file + + These are improvements to existing features: + * modify make_hash to allow building with address-sanitizer, + assuming that --disable-leaks is configured. + * move SCREEN field for use_tioctl data before the ncursesw fields, + and limit that to the sp-funcs configuration to improve termlib + compatibility + * modify db-iterator: + + ignore zero-length files in db-iterator; these are useful for + instance to suppress $HOME/.terminfo when not wanted. + + modify update_getenv to ensure that environment variables + which are not initially set will be checked later if an + application happens to set them + * modify _nc_outc_wrapper to use the standard output if the screen + was not initialized, rather than returning an error. + * improve checks for low-level terminfo functions when the terminal + has not been initialized. + * modify set_curterm to update ttytype[] data used by longname/p> + * modify _nc_get_screensize to allow for use_env and use_tioctl + state to be per-screen when sp-funcs are configured, better + matching the behavior when using the term-driver configuration. + * remove an early-return from _nc_do_color, which can interfere with + data needed by bkgd when ncurses is configured with extended + colors + * incorporate A_COLOR mask into COLOR_PAIR, in case user application + provides an out-of-range pair number + * modify logic for endwin-state to be able to detect the case where + the screen was never initialized, using that to trigger a flush of + ncurses' buffer for mvcur, e.g., in the sample program dots_mvcur + for the term-driver configuration. + + These are corrections to existing features: + * fixes for writing extended color pairs in putwin. + * modify no-leaks code for lib_cur_term.c to account for the tgetent + cache. + * amend handling of the repeat_char capability in EmitRange to avoid + scope creep: translate the character to the alternate character + set when the alternate character set is enabled, and do not use + repeat_char for characters past 255. + * improve wide-character implementation of myADDNSTR in + frm_driver.c, which was inconsistent with the normal + implementation. + * modify winnstr and winchnstr to return error if the output pointer + is null, as well as adding a null pointer check of the window + pointer for better compatibility with other implementations. + * modify setupterm to save original tty-modes so that erasechar + works as expected. Also modify _nc_setupscreen to avoid redundant + calls to get original tty-modes. + * modify wattr_set and wattr_get to return ERR if win-parameter is + null, as documented. + * correct order of initialization for traces in use_env and + use_tioctl versus first _tracef calls. + * correct parameters for copywin call in _nc_Synchronize_Attributes + * flush the standard output in _nc_flush for the case where SP is + zero, e.g., when called via putp. This fixes a scenario where + "tput flash" did not work after changes in 20130112. + * amend internal use of tputs to consistently use the number of + lines affected, e.g., for insert/delete character operations. + While merging terminfo source early in 1995, several descriptions + used the "*" proportional delay for these operations, prompting a + change in doupdate. + * correct return-value of extended putwin. + * double-width multibyte characters were not counted properly in + winsnstr and wins_nwstr. + * amend fix for _nc_ripoffline from 20091031 to make test/ditto.c + work in threaded configuration. + * modify _nc_viscbuf2 and _tracecchar_t2 to trace wide-characters as + a whole rather than their multibyte equivalents. + * minor fix in wadd_wchnstr to ensure that each cell has nonzero + width. + * move PUTC_INIT calls next to wcrtomb calls, to avoid carry-over of + error status when processing Unicode values which are not mapped. + * add missing assignment in lib_getch.c to make notimeout work Program improvements - Utilities - - Most of the termcap-related changes based on development of [34]tctest - (termcap library checker) are implemented in the tic and infocmp - programs rather than affecting the library. As noted in the - [35]discussion of tctest, ncurses's ability to translate between - terminfo and termcap formats has been improved at different times, but - subject to feedback from "real" termcap users. There are very few of - those. Nowadays, virtually all termcap users are using ncurses (or - NetBSD, with its own terminfo library) and their programs are actually - using terminfo rather than termcap data. - - Still, there are a few. A comment about the translation of the ASCII - NUL character prompted a review: - * Both terminfo and termcap store string capabilities as - NUL-terminated strings. - * In terminfo, a \0 in a terminal description is stored as \200. - * There are no (known) terminals which would behave differently when - sent \0 or \200. - * When translating to terminfo format (or displaying a printable - version of an entry using infocmp), ncurses shows \200 as \0. - * It has done this since 1998 (quoting from the NEWS file): - -[36]980103 -... - + modify _nc_tic_expand() to generate \0 rather than \200. -... - + correct translation of terminfo "^@", to \200, like \0. - - * However, the _nc_tic_expand function (which optionally produces - terminfo or termcap format) did not address this special case for - termcap. Even the later 4.4BSD [37]cgetstr interprets a \0 - literally, ending that string (rather than using the terminfo - improvement). - - As a result of the review, several improvements were made to ncurses - translation to/from termcap format -- and improving the checks made in - tic for consistency of entries. Most of these are not of general - interest, except for two new command-line options for tic and infocmp: - * the "-0" option generates termcap/terminfo source on a single - line. - * the "-K" option provides stricter BSD-compatibility for termcap - output. + While reviewing user feedback, it became apparent that the differences + between [20]reset (an alias for tset) and "tput reset" were confusing: + * one ([21]tset) updated the terminal modes, but used only part of + the terminfo capabilities for initialization, while + * the other ([22]tput) used all of the terminal capabilities while + neglecting the terminal modes. + + On further investigation, it turned out that the differences were + largely an accident due to the way those programs had evolved. + + This release eliminates the unnecessary differences, using the same + approach for tput's init (initialization), reset and clear operations + as the separate [23]reset and [24]clear programs. Doing this does not + change the command-line options; existing scripts are unaffected. + + These are the user-visible changes for the three programs (tput, tset + and clear): + * add the terminal-mode parts of "reset" (aka tset) to the "tput + reset" command, making the two almost the same except for + window-size. + * improve tput's check for being called as "init" or "reset" to + allow for transformed names. + * add "clear" as a possible link/alias to tput. + * amend changes for tput to reset tty modes to "sane" if the program + is run as "reset", like tset. Likewise, ensure that tset sends + either reset- or init-strings. + * add -x option to clear/tput to make the E3 extension optional + * add functionality of "tset -w" to tput, like the "-c" feature this + is not optional in tput. + * add options -T and -V to clear command for compatibility with + tput. + * drop long-obsolete "-n" option from tset. + * modify tset's assignment to TERM in its output to reflect the name + by which the terminal description is found, rather than the + primary name. That was an unnecessary part from the initial + conversion of tset from termcap to terminfo. The termcap library + in 4.3BSD did this to avoid using the short 2-character name + * remove a restriction in tput's support for termcap names which + omitted capabilities normally not shown in termcap translations + * add usage message to clear command + * improve usage messages for tset and tput. Other user-visible improvements and new features include: - * added "-D" option to tic and infocmp, to show the database - locations that it could use. - * added "-s" option to toe, to sort its output. - * extended "-c" and "-n" options of infocmp to allow comparing more - than two entries. - * modified toe's report when "-a" and "-s" options are combined, to - add a column showing which entries belong to a given database. - * modified the clear program to take into account the "E3" extended - capability to clear the terminal's scrollback buffer. + * modify tic/infocmp display of numeric values to use hexadecimal + when they are "close" to a power of two, making the result more + readable. + * add "-W" option to tic/infocmp to force long strings to wrap. + + This is in addition to the "-w" option which attempts to fit + capabilities into a given line-length. + + If "-f" option splits line, do not further split it with + "-W". + + Begin a new line when adding "use=" after a wrapped line. + * add "-q" option to infocmp to suppress the "Reconstructed from" + comment from the header, and a corresponding option to tic to + suppress all comments from the "tic -I" output. + * Sorted options in usage message for infocmp, to make it simpler to + see unused letters. + * Updated usage message for tic, adding "-0" option. + * add infocmp/tic "-Q" option, which allows one to dump the compiled + form of the terminal entry, in hexadecimal or base64: + + A "b64:" prefix in the TERMINFO variable tells the terminfo + reader to use base64 according to RFC-3548 as well as + RFC-4648 url/filename-safe format. + + A "hex:" prefix tells the terminfo reader to accept + hexadecimal data as generated by "infocmp -0qQ1". + + Other less-visible improvements and new features include: + * modify utility headers such as tic.h to make it clearer which are + externals that are used by tack. + * add "reset" to list of programs whose names might change in + manpages due to program-transformation configure options. + * modify "-T" option of clear and tput to call use_tioctl to obtain + the operating system's notion of the screensize if possible. + * add check in tput for init/reset operands to ensure those use a + terminal. + * modify programs clear, tabs, tput and tset to pass the actual tty + file descriptor to setupterm rather than the standard output or + error, making padding work. + * change tset's initialization to allow it to get settings from the + standard input as well as /dev/tty, to be more effective when + output or error are redirected. + * amend check in tput, tabs and clear to allow those to use the + database-only features in cron if a "-T" option gives a suitable + terminal name. + * improve error message from tset/reset when both stderr/stdout are + redirected to a file or pipe. + + Several of the less apparent features deal with translation of + terminfo to termcap (and the reverse), with corresponding checks by + tic: + * modify check in fmt_entry to handle a cancelled reset string. Make + similar fixes in other parts of dump_entry.c and tput.c + * correct read of terminfo entry in which all strings are absent or + explicitly cancelled. Before this fix, the result was that all + were treated as only absent. + * modify infocmp to suppress mixture of absent/cancelled + capabilities that would only show as "NULL, NULL", unless the "-q" + option is used, e.g., to show "-, @" or "@, -". + * correct a warning from tic about keys which are the same, to skip + over missing/cancelled values. + * add check in tic for use of bold, etc., video attributes in the + color capabilities, accounting whether the feature is listed in + ncv. + * add check in tic for unnecessary use of "2" to denote a shifted + special key. + * improve check in tic for delays by also warning about beep/flash + when a delay is not embedded, or if those use the VT100 reverse + video escape without using a delay. + * improve checks in trim_sgr0, comp_parse.c and parse_entry.c, for + cancelled string capabilities. + * add check in tic for some syntax errors of delays, as well as use + of proportional delays for non-line capabilities. + * add check in tic for conflict between ritm, rmso, rmul versus + sgr0. + * add check in _nc_parse_entry for invalid entry name, setting the + name to "invalid" to avoid problems storing entries. + * improve _nc_tparm_analyze, using that to extend the checks made by + tic for reporting inconsistencies between the expected number of + parameters for a capability and the actual. + * remove tic warning about "^?" in string capabilities, which was + marked as an extension; however all Unix implementations support + this and X/Open Curses does not address it. On the other hand, + [25]BSD termcap did not support this feature (until the + [26]mid-1990s). + in _nc_infotocap, added a check to ensure that terminfo "^?" is + not written to termcap. + * modify sscanf calls in _nc_infotocap for patterns "%{number}%+%c" + and "%'char'%+%c" to check that the final character is really "c", + avoiding a case in icl6404 which cannot be converted to termcap. + * in _nc_tic_expand and _nc_infotocap, improved string-length check + when deciding whether to use "^X" or "\xxx" format for control + characters, to make the output of tic/infocmp more predictable. + * limited termcap "%d" width to 2 digits on input, and use "%2" in + preference to "%02" on output. + * correct terminfo/termcap conversion of "%02" and "%03" into "%2" + and "%3"; the result repeated the last character. Examples Along with the library and utilities, many improvements were made to - the [38]ncurses-examples. Some were made to allow building (and - comparison-testing) against NetBSD curses and PDCurses. Both lack some - of the X/Open Curses features, necessitating customization. But this - activity was useful because it showed some remaining performance - issues (which have been resolved in this release). - - These changes were made to verify compatibility or compare performance - of ncurses: - * made workarounds for compiling test-programs with NetBSD curses, - though it lacks some common functions such as [39]use_env. - * added dots_termcap test-program - * added dots_curses test-program, for comparison with the low-level - examples. - * added test_setupterm test-proram to demonstrate normal/error - returns from the setupterm and restartterm functions. - * added "-d", "-e" and "-q" options to the demo_terminfo and - demo_termcap test-programs. - * added "-y" option to demo_termcap and test/demo_terminfo - test-programs to demonstrate behavior with/without extended - capabilities. - * modified demo_termcap and demo_terminfo test-programs to make - their options more directly comparable, and add "-i" option to - specify a terminal description filename to parse for names to - lookup. - * rewrote the tests for [40]mvderwin and test for recursive - [41]mvwin in the movewindow test-program. - - These changes were made to help with the MinGW port: - * added test-screens to the ncurses test-program to show - 256-characters at a time, to help with MinGW port. - * modified the view test-program to load UTF-8 when built with MinGW - by using regular win32 API because the MinGW functions mblen and - mbtowc do not work. - * added "-s" option to the view test-program to allow it to start in - single-step mode, reducing size of trace files when it is used for - debugging MinGW changes. - - These changes were made to verify new extensions in ncurses: - * added [42]form_driver_w entrypoint to wide-character forms - library, as well as form_driver_w test-program. - * modified ncurses test-program's b/B tests to display lines only - for the attributes which a given terminal supports, to make room - for an italics test. - * modified ncurses test-program, adding "-E" and "-T" options to - demonstrate use_env versus use_tioctl. - * modified ncurses test-program's c/C tests to cycle through subsets - of the total number of colors, to better illustrate - 8/16/88/256-colors by providing directly comparable screens. - * modified the ncurses test-program to also show position reports in - 'a' test. - - These changes were made to make the examples more useful: - * added scripts for building dpkg and rpm test-packages - * modified the hanoi test-program to show the minimum number of - moves possible for the given number of tiles. - * modified the knight test-program to show the number of choices - possible for each position in automove option, e.g., to allow user - to follow Warnsdorff's rule to solve the puzzle. + the [27]ncurses-examples. + + These changes were made to demonstrate new extensions in ncurses: + * add demo_new_pair program, to demonstrate [28]alloc_pair, + [29]find_pair and [30]free_pair functions. + This program iterates over the possible color combinations, + allocating or initializing color pairs. For best results, choose + screen-width dividing evenly into the number of colors. e.g., + + 32x64,32x128 256 colors + 24x44,24x88 88 colors + 32x64,24x128 16 colors + + * add extended_color program, like the older color_set program, but + using the extended color functions, with and without the + SP-functions interface. + * add picsmap program to fill in some testing issues not met by + dots, using this as the third example in a comparison of the + [31]ncurses versus slang libraries. + The program can directly read X bitmap and pixmap files, + displaying a picture. It can read other image files using + ImageMagick's convert program to translate the image into text. + For 16-, 88- and 256-color terminal descriptions, picsmap can load + a palette file which tells it which color palette entries to use. + For direct-colors, the terminal descriptions use the RGB extension + capability. - Terminal database + There are other new example programs and a few scripts: + * add dots_xcurses program to illustrate a different approach used + for extended colors which can be contrasted with dots_curses. + * add list_keys program show function keys for one or more terminal + descriptions. It uses ncurses's convention of modifiers for + special keys, based on xterm. + * add padview program, to compare pads with direct updates in the + view program. + * add sp_tinfo program to exercise the SP-functions extension of the + low-level terminfo library. + * add test-programs for termattrs and term_attrs functions. + * add test_sgr program to exercise all combinations of the sgr + capability. + * add tput-colorcube demo script, imitating xterm's 88- and + 256-color scripts using tput. + * add tput-initc script to demonstrate how tput may be used to + initialize a color palette from a data file. + + A variety of improvements were made to existing programs, both new + features as well as options added to make the set of programs more + consistent. + + The ncurses program is the largest; a proportionately large number of + changes were made to it: + * modify a/A screens to make exiting on an escape character depend + on the start of keypad and timeout modes, to allow better testing + of function-keys. + add "t" toggle for notimeout function. + * modify layout of b/B screens to allow for additional annotation on + the right margin; some terminals with partial support did not + display well. + * modify c/C screens to allow for extended color pairs. + add z/Z zoom feature to make extended color pairs easier to test. + modify test-screens to take advantage of wide screens, reducing + the number of lines used for 88- and 256-colors. + * modify "d" edit-color screen to optionally read xterm color + palette directly from terminal, as well as handling KEY_RESIZE and + screen-repainting with control/L and control/R. + * add examples to "F" screen for WACS_D_PLUS and WACS_T_PLUS. + * improve "g" screen, correcting ifdef which made the legend not + reflect changes to keypad- and scroll-modes. Added check for + return-value of putwin. + * make "s" test easier to understand which subtests are available + add a corresponding "S" wide-character overlap test-screen. + * add "v" screen to show baudrate and other values. + + These changes were made to the other examples: + * modify blue program to use Unicode values for card-glyphs when + available, as well as improving the check for CP437 and CP850. + * improve demo_menus program, allowing mouse-click on the + menu-headers to switch the active menu. This requires a new + extension option O_MOUSE_MENU to tell the menu driver to put mouse + events which do not apply to the active menu back into the queue + so that the application can handle the event. + * correct logic in demo_terminfo program for "-f" option + * modify ditto program to allow $XTERM_PROG environment variable to + override "xterm" as the name of the program to run in the threaded + configuration. + * add several options to the "dots" test-programs. + * modify filter program: + + illustrate an alternative to getnstr, that polls for input + while updating a clock on the right margin as well as + responding to window size-changes. + + adapt logic used in [32]dialog [33]"--keep-tite" option for + filter program as the "-a" option. When set, filter attempts + to suppress the alternate screen. + * modify knight program to provide the "slow" solution for small + screens using "R", noting that Warnsdorf's method is easily done + with "a". + * modify the savescreen program to add test patterns that exercise + 88-, 256-, etc., colors. + * add options to test_arrays, for selecting termcap vs terminfo, + etc. + * modify the view program: + + expand tabs using the ncurses library rather than in the + test-program. + + eliminate the "-n" option by simply reading the whole file. + + implement page up/down commands. + + remove the very old SIGWINCH example; just use KEY_RESIZE. + * improve animation in xmas program by adding a time-delay in + blinkit. + * modify several test-programs which call use_default_colors to + consistently do this only if the "-d" option is given. + * modify the install-rule for ncurses-examples to put the data files + in the data directory, e.g., /usr/share/ncurses-examples. + * modify several test programs to use new popup_msgs function, + adapted from the help-screen used in the edit_field program. + * modify test data for xterm palettes to use the newer + color4/color12 values. + * improve the tracemunch script: + + show screenXX pointers and thread identifiers as names. + + chang address-parameters of add_wch, color_content and + pair_content to dummy parameters. - This release provides improvements to tic's "-c" checking option, - which was used for example to - * make sgr in several entries agree with other caps. - * correct padding in some entries where earlier versions had - miscounted the number of octal digits. + Terminal database There are several new terminal descriptions: - * [43]mlterm is now aliased to mlterm3 - * [44]nsterm is now derived from nsterm-256color - * [45]putty-sco - * [46]teken is FreeBSD's "xterm" console. - * [47]terminator - * [48]terminology - * [49]tmux is derived from screen. - * several screen.XXX entries support the respective variations for - 256 colors. - * [50]simpleterm is now 0.5 - * [51]vte is aliased to vte-2012 - * [52]vt520ansi + + dumb-emacs-ansi, dvtm, dvtm-256color, fbterm, iterm2, linux-m1 + minitel entries, putty-noapp, viewdata, and vt100+4bsd + building-block. + + xterm+noalt, xterm+titlestack, xterm+alt1049, xterm+alt+title + building blocks and xterm+direct, xterm+indirect, xterm-direct. + from [34]xterm patch #331. + + several other "-direct" descriptions to address the differences of + other terminal emulators versus xterm-direct. + + There are many changes to existing terminal descriptions. Some were + updates to several descriptions: + * use xterm+sm+1006 in several terminal descriptions which were + validated as supporting the extended mouse feature for their + respective terminal emulators. + * corrected sgr/sgr0 strings in a few cases reported by tic, making + those correspond to the non-sgr settings where they differ, but + otherwise use ECMA-48 consistently. + * add 0.1sec mandatory delay to flash capabilities using the VT100 + reverse-video control + + while others affected specific descriptions.

Because those did not correspond to useful terminal + descriptions, most users are unaffected. Configuration changes Major changes - The ncurses 6.0 configure script makes changes to the default value of - several configure options, depending on the --with-abi-version option - (i.e., whether its value is "5" or "6"): - - --enable-const - Feature introduced in [68]970405 supports the use of const - where X/Open Curses should have, but did not. NetBSD curses - does something similar with const. - - --enable-ext-colors - Extends the cchar_t structure to allow more than 16 colors to - be encoded. This applies only to the wide-character - (--enable-widec) configuration. - - --enable-ext-mouse - Modifies the encoding of mouse state to make room for a 5th - mouse button. That allows one to use ncurses with a wheel mouse - with xterm or similar X terminal emulators. - - --enable-ext-putwin - Modifies the file-format written by putwin to use printable - text rather than binary files, allowing getwin to read screen - dumps written by differently-configured ncurses libraries. The - extended getwin can still read binary screen dumps from the - same configuration of ncurses. This does not change the ABI - (the binary interface seen by calling applications). - - --enable-interop - Modifies the FIELDTYPE structure used for the form library to - make it more generic. - - --enable-lp64 - Allows an application to define _LP64 to declare chtype and - mmask_t as simply "unsigned" rather than the configured types - using the --with-chtype and --with-mmask_t options. - - --enable-sp-funcs - Compile-in support for extended functions which accept a SCREEN - pointer, reducing the need for juggling the global SP value - with [69]set_term and [70]delscreen. - - --with-chtype=uint32_t - Makes chtype explicitly a 32-bit unsigned value. - - --with-mmask_t=uint32_t - Makes mmask_t explicitly a 32-bit unsigned value. - - --with-tparm-arg=intptr_t - X/Open Curses declares [71]tparm using long for each of the - parameters aside from the formatting string, presuming that - long and char* are the same size. This configure option uses - intptr_t which provides a better guarantee of the sizes. - - The configure script no longer checks for antique compilers; c89 is - assumed as a minimum. There are a few features from later revisions - which are used when available. The configure script makes checks to - turn on useful warnings from clang, gcc and icc. You should be able to - build ncurses 6.0 with any of the current (or not so current) C - compilers available in 2015. - - The configure script, by the way, makes changes which do not work with - systems whose /bin/sh is non-POSIX. This mainly affects Solaris (the - other vendor unix systems have followed the POSIX guidelines for the - past twenty years). If you must build on Solaris, its [72]xpg4 - binaries suffice, e.g., - - #!/bin/sh - WHAT=`hostname|sed -e 's/\..*//'` - OUT=configure.out - cat >>$OUT <&1 | tee -a $OUT - - Other major changes to the configure script include: - * ABI 6 is now the default, intending that the existing ABI 5 should - build as before using the "--with-abi-version=5" option. - * added --with-extra-suffix option to help with installing - nonconflicting ncurses6 packages, e.g., avoiding header- and - library-conflicts. - NOTE: as a side-effect, this renames - - adacurses-config to adacurses5-config and - adacursesw-config to adacursesw5-config - * the configure script looks for gnatgcc if the Ada95 binding is - built, in preference to the default gcc/cc. The script also - ensures that the Ada95 binding is built with the level of - optimization as the C libraries. - * the configure script captures define's related to -D_XOPEN_SOURCE - from the configure check and adds those to the *-config and *.pc - files, to simplify use for the wide-character libraries. + This release provides a new binary format for terminal descriptions + that use extended numeric capabilities. Applications built with the + wide-character ncursesw library can use these extended numbers. + * This includes utilities such as tic and infocmp, because (as noted + in [89]New features), the feature relies upon an extension to the + low-level tinfo library. + * A few software packagers use a configuration option of ncurses + which allows the low-level tinfo library to be shared between the + high-level ncurses and ncursesw libraries. This new feature was + designed to work in that configuration as well. + + Other applications (i.e., using the 8-bit ncurses library) which read + the extended terminal descriptions see those numeric capabilities set + to the maximum value for a signed 16-bit number. + + Older versions of ncurses' tic accept out-of-range numeric + capabilities, storing those as the maximum value for a signed 16-bit + number. Other implementations of curses (mentioned in the discussion + of [90]picsmap) give zero for these out-of-range capabilities. Configuration options - There are several new (or extended) configure options: - - --disable-db-install - Do not install the terminal database. This is used to omit - features for packages, as done with --without-progs. The option - simplifies building cross-compile support packages. - - --disable-gnat-projects - This option is used for regression testing - - --disable-lib-suffixes - Suppress the "w", "t" or "tw" suffixes which normally would be - added to the library names for the --enable-widec and - --with-pthread options. - - --with-cxx-shared - When --with-shared is set, build libncurses++ as a shared - library. This implicitly relies upon building with gcc/g++, - since other compiler suites may have differences in the way - shared libraries are built. libtool by the way has similar - limitations. - - --with-hashed-db - Extended this configure option to simplify building with - different versions of Berkeley database using FreeBSD ports. - - --with-pc-suffix - If ".pc" files are installed, optionally add a suffix to the - files and corresponding package names to separate unusual - configurations. If no option value is given (or if it is - "none"), no suffix is added. This option is used in the test - package for ncurses6. - - --with-xterm-kbs - Configure xterm's terminfo entries to use either BS (^H, i.e., - ASCII backspace) or DEL (^?, or 127). + These changes provide support for tack 1.08, released in [91]July + 2017: + * add --without-tack configure option to refine --with-progs + configure option. Normally tack is built outside the ncurses tree, + but a few packagers combine it during the build. If term_entry.h + is installed, there is no advantage to in-tree builds. + * adjust configure-script to define HAVE_CURSES_DATA_BOOLNAMES + symbol needed for tack 1.08 when built in-tree. Rather than + relying upon internal "_nc_" functions, tack now uses the boolean, + number and string capability name-arrays provided by ncurses and + SVr4 Unix curses. It still uses term_entry.h for the definitions + of the extended capability arrays. + * add dependency upon ncurses_cfg.h to tic's header-files; any + program using tic-library will have to supply this file. Legacy + tack versions supply this file; ongoing tack development has + dropped the dependency upon tic-library and new releases will not + be affected. + + Other changes to the configure-script and generated files include + * add configure options to disable checks for form, menu and panel + libraries so that ncurses-examples can be built with non-SVr4 + curses implementations. + * add configure option --enable-opaque-curses for ncurses library + and similar options for the other libraries. + * add configure option --disable-wattr-macros for use in cases where + one wants to use the same headers for ncurses5/ncurses6 + development, by suppressing the wattr* macros which differ due to + the introduction of extended colors + * modify configure macro for shared-library rules to use -Wl,-rpath + rather than -rpath to work around a bug in scons + * improve ncurses-examples' configure script to define as needed + NCURSES_WIDECHAR for platforms where _XOPEN_SOURCE_EXTENDED does + not work. Also modified the test program to ensure that if + building with ncurses, that the cchar_t type is checked, since + that is normally (since [92]20111030) ifdef'd depending on this + test. + * modify configure script to handle the case where tic-library is + renamed, but the --with-debug option is used by itself without + normal or shared libraries + * modify editing script which generates resulting.map to work with + the clang configuration on recent FreeBSD, which gives an error on + an empty "local" section. + * improve configure check for setting the WILDCARD_SYMS variable; on + ppc64 the variable is in the Data section rather than Text. + * correct result of configure option --without-fallbacks, which + caused FALLBACK_LIST to be set to "no" + * modify --with-pkg-config-libdir option to make it possible to + install ".pc" files even if pkg-config is not found. Limit this + change, to suppress the actual install if it is not overridden to + a valid directory at install time. + * disallow "no" as a possible value for --with-shlib-version option, + overlooked in cleanup-changes for [93]20000708. Portability - MinGW - - Most of the portability-related work since [73]ncurses 5.9 extended - and improved the MinGW port introduced in [74]ncurses 5.8. - - The MinGW port can be readily cross-compiled: - * modified configure script to allow creating dll's for MinGW when - cross-compiling. - * enforced Windows-style path-separator if cross-compiling, - * added scripts for test-builds of cross-compiled packages for - ncurses6 to MinGW. - * added pc-files to the MinGW cross-compiling test-packages. - * added script for building test-packages of binaries cross-compiled - to MinGW using NSIS. - * added nc_mingw.h to installed headers for MinGW port; this is - needed for cross-compiling [75]ncurses-examples. - * added test-packages for cross-compiling ncurses-examples using the - MinGW test-packages. - - The MinGW-specific Windows driver accounts for several changes: - * wide-character display is made usable by replacing MinGW's - non-working wcrtomb and wctomb functions. - * implemented some display features: [76]beep, [77]flash, - [78]curs_set. - * the driver handles repainting on endwin/refresh combination. - * modified treatment of TERM variable for MinGW port to allow - explicit use of the Windows console driver by checking if $TERM is - set to "#win32console" or an abbreviation of that. - * the Windows driver also matches the special TERM value "unknown" - * the driver now returns characters for special keys, (like ansi.sys - does), when keypad mode is off, rather than returning nothing at - all. - * the driver checks a new environment variable [79]NCURSES_CONSOLE2 - to optionally work around a deficiency in Console2 (and its - descendent ConsoleZ) which hang when an application creates a - console buffer. - - Finally, there are other improvements: - * MinGW is one of the configurations where ncurses installs by - default into /usr - * configuration for cross-compiling uses AC_CHECK_TOOLS in - preference to AC_PATH_PROGS when searching for ncurses*-config, - e.g., in Ada95/configure and test/configure. - * extend Windows support to work with MSYS2; - + this works with a scenario where there is an ANSI-escape - handler such as ansicon running in the console window. - + wrap isatty calls with a macro, provide a corresponding set - of support routines to address differences between MinGW and - MSYS2. - * ensure WINVER is defined in makefiles rather than using headers. - * add check for the gnatprep "-T" option. - * work around a bug introduced by [80]gcc 4.8.1 in MinGW which - breaks "trace" feature. - * add a driver-name method to each of the drivers. - - Other ports - - These changes affect certain platforms (ports): - * the configure script knows how to build shared libraries with - DragonFlyBSD and Interix. - * support for AIX shared libraries is improved, tested with AIX 5.3, - 6.1 and 7.1 with both gcc 4.2.4 and cc: - + the shared-library suffix for AIX 5 and 6 is now ".so" - + the -brtl option is used with AIX 5-7; it is needed to link - with the shared libraries. - * the configure --enable-pc-files option takes into account the - [81]PKG_CONFIG_PATH variable. - * the configure option --with-pkg-config-libdir provides control - over the actual directory into which pc-files are installed. - * the build scripts add explicit -ltinfo, etc., to the generated - ".pc" file when ld option "--as-needed" is used, or when ncurses - and tinfo are installed without using rpath. - * the configure script disallows conflicting options - "--with-termlib" and "--enable-term-driver". - * the check for missing c++ compiler to work when no error is - reported, and no variables set is improved (see note for - [82]20021206). - * the misc/gen_edit.sh script selects a "linux" entry which works - with the current kernel rather than assuming it is always - "linux3.0" - * the test/configure script makes it simpler to override names of - curses-related libraries, to help with linking with pdcurses in - MinGW environment. - * the configure-script/ifdef's allow the BSD OLD_TTY feature to be - suppressed if the type of ospeed is configured using the option - --with-ospeed to not be a short. By default, it is a short for - termcap-compatibility. - * the MKlib_gen.sh script works around a recent change in gcc 5 - (released [83]mid-2015) which essentially emits multiple #line - statements for the same position in a file. - * the configure script works with Minix3.2 (see [84]note on - portability) - * OS/2 redux: - + the configure script supports OS/2 kLIBC. - + the --with-lib-prefix option allows configuring for old/new - flavors of OS/2 EMX. - * improved configure-script checks for _XOPEN_SOURCE: - + the definition works starting with Solaris 10. - + the definition is suppressed for IRIX64, since its header - files have a conflict versus _SGI_SOURCE. + Many of the portability changes are implemented via the configure + script: + * improve configure script's CF_CC_ENV_FLAGS macro to allow for + compiler wrappers such as ccache. This change moves only the + preprocessor, optimization and warning flags to CPPFLAGS and + CFLAGS, leaving the residue in CC. That happens to work for gcc's + various "model" options, but may require tuning for other + compilers. + * modify ncurses-examples' configure script to use pkg-config for + the extra form/menu/panel libraries, to be more consistent with + the handling of the curses/ncurses library. + * add configuration checks to build with [94]NetBSD curses, which + for example lacks [95]use_env. + * change ncurses-examples to use attr_t vs chtype to follow X/Open + documentation more closely since Solaris xpg4-curses uses + different values for WA_xxx vs A_xxx that rely on attr_t being an + unsigned short. Tru64 aka OSF1, HPUX, AIX did as ncurses does, + equating the two sets. + * modify several test programs to reflect that ncurses honors + existing signal handlers in initscr, while other implementations + do not. + * add configure check for openpty to ncurses-examples' configure + script, for ditto. + * improve check for working poll function by using posix_openpt as a + fallback in case there is no valid terminal on the standard input + * modify ncurses-examples' configure script to check for pthread + dependency of ncursest or ncursestw library when building the + ncurses examples, e.g., in case weak symbols are used. + * add checks in ncurses-examples' configure script for some + functions neither in 4.3BSD curses, nor based on X/Open Curses: + + modify a loop limit in firework.c to work around absense of + limit checks in some libraries. + + fill the last row of a window with "?" in firstlast if waddch + does not return ERR on the lower-right corner. + * build-fixes for the Portland Group (PGI) compilers + + accept whitespace in sed expression for generating expanded.c + + modify configure check that g++ compiler warnings are not + used. + + add configure check for -fPIC option needed for shared + libraries. + * modify configure script for clang as used on FreeBSD, to work + around clang's differences in exit codes vs gcc. + * fixes for configure/build using clang on OSX + + do not redefine "inline" in ncurses_cfg.h; this was + originally to solve a problem with gcc/g++, but is aggravated + by clang's misuse of symbols to pretend it is gcc. + + add braces to configure script to prevent unwanted addition + of "-lstdc++" option to the CXXLIBS symbol. + + improve/update test-program used for checking existence of + stdc++ library. + + if $CXXLIBS is set, the linkage test uses that in addition to + $LIBS. + * fixes for OS/2: + + use button instead of kbuf[0] in EMX-specific part of + lib_mouse.c + + support building with libtool on OS/2 + + use stdc++ library with OS/2 kLIBC + + clear configure script's cf_XOPEN_SOURCE for OS/2, to work + with its header files + * add "newer" baudrate symbols to the [96]baudrate function in the + ncurses library as well as to a corresponding table in tset. + * modify ncurses-examples savescreen to work with AIX and HPUX. + * define WIN32_LEAN_AND_MEAN for MinGW port, making builds faster. + * add a configure check for wcwidth versus the ncurses line-drawing + characters, to use in special-casing systems such as Solaris. + Solaris, however, requires a special case that maps Unicode + line-drawing characters into the acsc string for non-Unicode + locales.

This is used to omit features for packages, as done with --without-progs. + --disable-echo + Use the option --disable-echo to make the build-log less verbose by + suppressing the display of the compile and link commands. This makes + it easier to see the compiler warnings. (You can always use "make -n" + to see the options that are used). + --disable-ext-funcs Disable function-extensions.

+

These notes are for ncurses + @VERSION@, released January 27, 2018.

This release is designed to be source-compatible with - ncurses 5.0 through 5.9; providing a - new application binary interface (ABI). Although the source can - still be configured to support the ncurses 5 ABI, the intent of the release is to - provide extensions which are generally useful, but - binary-incompatible with ncurses - 5:

+ ncurses 5.0 through 6.0; providing + extensions to the application binary interface (ABI). Although + the source can still be configured to support the ncurses 5 ABI, the intent of the release is to + provide extensions to the ncurses + 6 ABI:

  • -

    Extend the cchar_t structure to allow more - than 16 colors to be encoded.

    +

    improve integration of tput + and tset

  • -

    Modify the encoding of mouse state to make room for a 5th - mouse button. That allows one to use ncurses with a wheel mouse with xterm or - similar X terminal emulators.

    +

    provide support for extended numeric capabilities.

-

There are, of course, numerous other improvements, - including

There are, of course, numerous other improvements, listed in + this announcement.

+ +

The release notes also mention some bug-fixes, but are focused + on new features and improvements to existing features since + ncurses 6.0 release.

+ +

Library + improvements

+ +

New + features

+ +

The improved integration of tput and tset + made only small changes to the libraries. However, supporting + extended numeric capabilities required a few changes:

  • -

    fixes made based on the Clang and Coverity static - analyzers.

    +

    The TERMINAL structure in + <term.h> is now opaque. Doing that allowed + making the structure larger, to hold the extended numeric + data.

    + +

    A few applications required changes during development of + ncurses 6.1 because those + applications misused the members of that structure, e.g., + directly modifying it rather than using + def_prog_mode.

  • -

    memory leak fixes using Valgrind

    -
    • -
+

Having made TERMINAL opaque (and because none + of the library functions use anything except a pointer to + TERMINAL), it was possible to increase the size + of the structure, adding to the end.

-

The release notes mention some bug-fixes, but are focused on - new features and improvements to existing features log since - ncurses 5.9 release.

+

Existing applications which were linked to the + ncurses 6.0 high-level + (ncurses, ncursesw) and low-level + (tinfo, tinfo) libraries should not require + re-linking since the binary interface did not change, nor did + the structure offsets with TERMINAL change.

-

While the intent of the release is to provide a new stable - ABI, there are other development activities which are summarized - below.

+

A few applications use the inner TERMTYPE + structure's offsets to refer to terminfo capabilities within + that structure. Again, those do not require modification + because their offsets within TERMINAL did not + change.

+ -
  • -

    The original release plan, e.g., for "5.10" was to improve - the MinGW port. Ultimately that was completed (wide-character - support, mouse, etc), but was deferred to focus on termcap - support and performance issues. Also, pinpointing the - problems with Console2 took a while.

    +

    When configured for wide-characters, i.e., + “ncursesw” the TERMINAL structure is + extended.

    + +

    The new data in TERMINAL holds the same + information as TERMTYPE, but with larger numbers + (“int” versus “short”). It is named + TERMTYPE2.

    + +

    The library uses this structure internally in preference + to TERMTYPE, referring to TERMTYPE + only to initialize it for applications that use the + capabilities defined in <term.h>

  • -

    A review of termcap compatibility in 2011 led to several - minor fixes in the library and improvements to utilities. To - do this properly, a review of the various extent termcap - implementations was needed.

    +

    When configured for 8-bit (narrow) characters, the + TERMTYPE2 structure is not used.

    +
    • -

    The termcap - library checker (tctest) (not part of ncurses) was one result. A followup review - of performance using ncurses-examples - in 2014 led to additional improvements.

    +
  • The updated application binary interface is 6.1.20171230 + (used for new versioned + symbols), although the interface changes were developed + several months previously.
    • +
+ +

The motivation for making this extension came from noticing + that + termcap applications could (though not + realistically) use larger numbers than would fit in 16-bits, + and the fact that the number of color pairs for a 256-color xterm + could not be expressed in terminfo (i.e., 32767 versus 65536). + Also, a few terminals support direct-colors, which could use the + extension.

+ +

Generally speaking, applications that use internal details of + a library are unsupported. There was exactly one exception for + ncurses: the tack program used the internal + details of TERMINAL, because it provides an + ncurses-specific feature for interactively modifying a terminfo + description and writing the updated description to a text-file. + It was possible to not only separate tack from these internal + details of ncurses, but to + generalize it so that the program works with Unix curses + (omitting the ncurses-specific feature). That was released as + + tack 1.08 in July + 2017.

+ +

While making changes to tack to + eliminate its dependency upon ncurses internals, the publicly-visible + details of those internals were reviewed, and some symbols were + moved to private header files, while others were marked + explicitly as ncurses internals. + Future releases of ncurses may + eliminate some of those symbols (such as those used by + tack 1.07) because they are + neither part of the API or the ABI.

+ +

Using the TERMTYPE2 extended numeric + capabilities, it is possible to support both color pair values + and color values past 32767. Taking compatibility into account, + developers readily understand that neither function signatures + nor structure offsets change. Also, existing functions have to + operate with the extended numbers. Most of that work is internal + to the library. For the external interfaces, a hybrid approach + was used:

+ +
    +
  • +

    X/Open Curses defined function prototypes such as + wattr_set with an unused parameter, for + “future” use. After 25 years, the future is here: + ncurses uses the parameter to + augment color pair values as described in the + manual page.

  • -

    Output buffering provided a further, but worthwhile - distraction. A bug report in 2012 regarding the use of signal - handlers in ncurses) pointed out - - a problem with the use of unsafe functions for handling - SIGTSTP. Other signals could be addressed with - workarounds; repairing SIGTSTP required a - different approach. The solution required changing internal - behavior of the library: how it handles output buffering.

    - -

    Now ncurses buffers its own - output, independently of the standard output. A few - applications relied upon the library's direct reuse of the - standard output buffering; however that is - unspecified behavior and has never been a - recommended practice. Identifying these applications as well - as refining the change to permit low-level applications to - work consistently took time.

    -
    • - -
  • -

    Since the introduction of the experimental support for 256 - colors early in 2005 - (released in ncurses - 5.5), there has been increased user interest. Almost all - packagers continue providing the ncurses ABI 5 which cannot - support 256 colors.

    -
    • - -
  • -

    Symbol versioning, or the lack of it in ncurses, is the - main reason why packagers would be reluctant to add a new - ncurses ABI.

    - -

    This release provides the new ABI along with - script-generated lists of versioned symbols which can be used - for both ABI 5 and 6 (with distinct names to keep the two - separate). This took time to development, as reported in - Symbol - versioning in ncurses.

    +

    Other functions such as those defining color pairs did not + have a corresponding reserved parameter. For those, + ncurses defines extended + versions such as init_extended_pair (versus + init_pair), init_extended_color + (versus init_color).

-

Library - improvements

+

Additionally, to improve performance other changes (and + extensions) are provided in this release:

-

Output - buffering

+
    +
  • +

    Several new functions simplify management of large sets of + color pairs: reset_color_pairs, + alloc_pair, find_pair and + free_pair.

    +
    • -

    X/Open curses provides more than one initialization - function:

    +
  • +

    New "RGB" extension capability for direct-color support is + used to improve performance of + color_content.

    +
    • -
      -
    • - initscr (the simplest) accepts no parameters.
      • +
    • +

      The internal colorpair_t is now a struct, + eliminating an internal 8-bit limit on colors

      +
      • -
    • - newterm accepts parameters for the stream input and - output
      • +
    • +

      Allocation for SCREEN's color-pair table + starts small, grows on demand up to the limit given in the + terminal description.

      +
      • -
    • - setupterm (the low-level function) accepts a parameter for - the file descriptor of the output.
      • +
    • +

      setcchar and getcchar now treat + a negative color-pair as an error.

      +
    -

    They are documented in X/Open as if - initscr calls newterm using - stdout for output stream, and in turn - newterm calls setupterm using - fileno(stdout) for the file descriptor. As long as - an implementation acts as if it does this, it conforms. - In practice, implementations do what is implied. This creates a - problem: the low-level setupterm function's file - descriptor is unbuffered, while newterm implies - buffered output. X/Open Curses says that all output is done - through the file descriptor, and does not say how the output - stream is actually used.

    - -

    Initially, ncurses used the file - descriptor (obtained from the output stream passed to - newterm) for changing the terminal modes, and relied - upon the output parameter of newterm for buffered - output. Later (to avoid using unsafe buffered I/O in signal - handlers), ncurses was modified to - use the file descriptor (unbuffered output) when cleaning up on - receipt of a signal. Otherwise (when not handling a signal), it - continued to use the buffered output.

    - -

    That approach worked reasonably well and as a side effect, - using the same buffered output as an application might use for - printf meant that no flushing was needed when - switching between normal- and screen-modes.

    - -

    There were a couple of problems:

    +

    Other + improvements

    + +

    These are new or revised features:

    • -

      to get good performance, curses (not only ncurses, but SVr4 curses in general) set an - output buffer using setbuf or similar function. - There is no standard (or portable) way to turn that output - buffer off, and revert to line-buffering. The - NCURSES_NO_SETBUF environment variable did make it - optional.

      +

      modify c++/etip.h.in to accommodate + deprecation of throw and throws in c++17

    • -

      to handle SIGTSTP (the “stop” - signal), ncurses relied upon - unsafe functions. That is, due to the complexity of the - feature, it relied upon reusing existing functions which - should not have been called via the signal handler.

      +

      add new function unfocus_current_field

      • -
    -

    Conveniently, solving the second problem (by making ncurses do its own output buffering) - also fixed the first one. But there were special cases to - resolve: - low-level functions such as mvcur, putp, vidattr - explicitly use the standard output. Those functions were reused - internally, and required modification to distinguish whether they - were used by the high-level or low-level interfaces.

    +
  • +

    add option to preserve leading whitespace in form + fields

    +
    • -

    Finally, there may still be a few programs which should be - modified to improve their portability, e.g., adding an

    +
  • +

    add a macro for is_linetouched and adjust the + function's return value to make it possible for most + applications to check for an error-return.

    +
    • -
    - 
    -fflush(stdout);
-
    -
    +
  • +

    add build-time utility report_offsets to help + show when the various configurations of tinfo library are + compatible or not.

    +
    • +
-

when switching from “shell” - mode to “program” - (curses) mode. Those are fairly rare because most programmers - have learned not to mix printf and printw.

- -

Symbol - versioning

- -

This release introduces symbol-versioning to ncurses because without it, the change of ABI - would be less successful. A lengthy discussion will be presented - in Symbol - versioning in ncurses. These - notes summarize what has changed, and what can be done with the - new release.

- -

Symbol-versioning allows the developers of a library to mark - each public symbol (both data and functions) with an identifier - denoting the library name and the version for which it was built. - By doing this, users of the library have a way to help ensure - that applications do not accidentally load an incompatible - library. In addition, private symbols can be hidden entirely.

- -

This release provides sample files for the four principal - configurations of ncurses libraries: - ncurses, ncursesw, - ncursest and ncursestw. Each sample is - given in two forms:

+

These were done to limit or ultimately deprecate features:

-
-
-
“.map”
+
    +
  • +

    drop two symbols obsoleted in 2004: + _nc_check_termtype, and + _nc_resolve_uses

    +
    • -
    These list all public symbols, together with version - names.
    +
  • +

    move _nc_tracebits, _tracedump + and _tracemouse to curses.priv.h, + since they are not part of the suggested ABI6.

    +
    • -
    “.sym”
    +
  • +

    mark some structs in form/menu/panel libraries as + potentially opaque without modifying API/ABI.

    +

    Program + improvements

    -

    As a special case, this release (which makes the final change - for ABI 5) is marked with release version 5.9 and patch date - 20150530.

    +

    While reviewing user feedback, it became apparent that the + differences between + reset (an alias for + tset) and “tput reset” were confusing:

    -

    Miscellaneous

    +
      +
    • one (tset) + updated the terminal modes, but used only part of the terminfo + capabilities for initialization, while
      • + +
    • the other (tput) + used all of the terminal capabilities while neglecting the + terminal modes.
      • +
    -

    The new release has several improvements for performance and - building. For instance:

    +

    On further investigation, it turned out that the differences + were largely an accident due to the way those programs had + evolved.

    + +

    This release eliminates the unnecessary differences, using the + same approach for tput's + init (initialization), reset and clear + operations as the separate + reset and + clear programs. Doing this does not change the + command-line options; existing scripts are unaffected.

    + +

    These are the user-visible changes for the three programs + (tput, tset and clear):

    • -

      several files in ncurses- and progs-directories were - modified to allow const data used in internal - tables to be put by the linker into the readonly text - segment.

      +

      add the terminal-mode parts of “reset” (aka tset) to the “tput + reset” command, making the two almost the same + except for window-size.

    • -

      various improvements were made to building the Ada95 - binding, both in simplifying the generated files as well as - improving the way it uses gnatmake

      +

      improve tput's check for + being called as “init” or “reset” to + allow for transformed names.

      • -
    -

    There are also new features in the libraries:

    +
  • +

    add “clear” as a possible link/alias to + tput.

    +
    • -
      -
    • added - use_tioctl function
      • +
    • +

      amend changes for tput to + reset tty modes to “sane” if the program is run + as “reset”, like tset. Likewise, ensure that tset sends either reset- or + init-strings.

      +
    • -

      added - wgetdelay to retrieve _delay member of WINDOW if it - happens to be opaque, e.g., in the pthread configuration.

      +

      add -x option to clear/tput + to make the E3 extension optional

    • -

      added - A_ITALIC extension.

      +

      add functionality of + “tset -w” to tput, like the + “-c” feature this is not optional in + tput.

    • -

      added form library extension - O_DYNAMIC_JUSTIFY option which can be used to override - the different treatment of justification for static versus - dynamic fields .

      +

      add options -T and -V to + clear command for + compatibility with tput.

    • -

      rewrote - putwin and - getwin, making an extended version which is capable of - reading screen-dumps between the wide/normal ncurses configurations. These are text - files, except for a magic code at the beginning:

      +

      drop long-obsolete “-n” option + from tset.

      +
      • -
      - 
      -0       string          \210\210        Screen-dump (ncurses)
-
      -
      +
    • +

      modify tset's assignment to + TERM in its output to reflect the name by which + the terminal description is found, rather than the primary + name. That was an unnecessary part from the initial + conversion of tset from + termcap to terminfo. The termcap library in 4.3BSD did this + to avoid using the short 2-character name

    • -

      several changes to mouse support include:

      +

      remove a restriction in tput's support for termcap names which + omitted capabilities normally not shown in termcap + translations

      +
      • + +
    • +

      add usage message to clear + command

      +
      • + +
    • +

      improve usage messages for tset and tput.

      +
      • +
    + +

    Other user-visible improvements and new features include:

    + +
      +
    • +

      modify tic/infocmp display of numeric values to use + hexadecimal when they are "close" to a power of two, making + the result more readable.

      +
      • + +
    • +

      add “-W” option to tic/infocmp + to force long strings to wrap.

        -
      • added decoder for xterm SGR 1006 mouse mode.
        • +
      • +

        This is in addition to the + “-w” option which attempts to + fit capabilities into a given line-length.

        +
        • -
      • added experimental support for - “%u” format to terminfo.
        • +
      • +

        If “-f” option splits line, + do not further split it with + “-W”.

        +
        • -
      • improved behavior of wheel-mice for xterm protocol: - noting that there are only button-presses for buttons - “4” and “5”, so there is no need to - wait to combine events into double-clicks .
        • +
      • +

        Begin a new line when adding + “use=” after a wrapped line.

        +
      • -
    -

    There are a few new configure options dealing with library - customization:

    +
  • +

    add “-q” option to infocmp to suppress the + “Reconstructed from” comment from + the header, and a corresponding option to tic to suppress all comments from the + “tic -I” output.

    +
    • -
    • -

      add “--enable-ext-putwin” - configure option to turn on the extended putwin/getwin. By - default, this is enabled for ABI 6 and disabled with ABI - 5.

      +

      Sorted options in usage message for infocmp, to make it simpler to see unused + letters.

    • -

      add “--enable-string-hacks” - option to control whether strlcat and strlcpy may be used. - Because ncurses already does the - requisite buffer-limit checks, this feature is mainly of - interest to quiet compiler-warnings on a few systems.

      +

      Updated usage message for tic, adding “-0” + option.

    • -

      add configure option - “--with-tparm-arg” to allow - tparm's parameters to be something more likely to be the - same size as a pointer, e.g., intptr_t (again, - the default is set for ABI 6).

      +

      add infocmp/tic “-Q” option, + which allows one to dump the compiled form of the terminal + entry, in hexadecimal or base64:

      + +
        +
      • A “b64:” prefix in the + TERMINFO variable tells the terminfo reader to + use base64 according to RFC-3548 as well as RFC-4648 + url/filename-safe format.
        • + +
      • A “hex:” prefix tells the + terminfo reader to accept hexadecimal data as generated by + “infocmp -0qQ1”.
        • +
    -

    Program - improvements

    - -

    Utilities

    - -

    Most of the termcap-related changes based on development of - tctest - (termcap library checker) are implemented in the tic and - infocmp programs rather than affecting the library. As noted in - the - discussion of tctest, ncurses's ability to translate between terminfo - and termcap formats has been improved at different times, but - subject to feedback from "real" termcap users. There are very few - of those. Nowadays, virtually all termcap users are - using ncurses (or NetBSD, with its - own terminfo library) and their programs are actually using - terminfo rather than termcap data.

    - -

    Still, there are a few. A comment about the translation of the - ASCII NUL character prompted a review:

    +

    Other less-visible improvements and new features include:

    • -

      Both terminfo and termcap store string capabilities as - NUL-terminated strings.

      +

      modify utility headers such as tic.h to make + it clearer which are externals that are used by tack.

    • -

      In terminfo, a \0 in a terminal description - is stored as \200.

      +

      add “reset” to list of programs + whose names might change in manpages due to + program-transformation configure options.

    • -

      There are no (known) terminals which would behave - differently when sent \0 or - \200.

      +

      modify “-T” option of + clear and tput to call use_tioctl to + obtain the operating system's notion of the screensize if + possible.

    • -

      When translating to terminfo format (or displaying a - printable version of an entry using infocmp), ncurses shows \200 as - \0.

      +

      add check in tput for + init/reset operands to ensure those use a terminal.

    • -

      It has done this since 1998 (quoting from the NEWS - file):

      - -
      - 
      -980103
-...
-        + modify _nc_tic_expand() to generate \0 rather than \200.
-...
-        + correct translation of terminfo "^@", to \200, like \0.
-
      -
      +

      modify programs clear, + tabs, tput and tset to pass the actual tty file + descriptor to setupterm rather than the standard output or + error, making padding work.

    • -

      However, the _nc_tic_expand function (which - optionally produces terminfo or termcap format) did not - address this special case for termcap. Even the later 4.4BSD - - cgetstr interprets a \0 literally, ending - that string (rather than using the terminfo - improvement).

      +

      change tset's + initialization to allow it to get settings from the standard + input as well as /dev/tty, to be more effective + when output or error are redirected.

      • -
    -

    As a result of the review, several improvements were made to - ncurses translation to/from termcap - format — and improving the checks made in tic for - consistency of entries. Most of these are not of general - interest, except for two new command-line options for tic and - infocmp:

    - -
    • -

      the “-0” option generates - termcap/terminfo source on a single line.

      +

      amend check in tput, + tabs and clear to allow those to use the + database-only features in cron + if a “-T” option gives a suitable + terminal name.

    • -

      the “-K” option provides stricter - BSD-compatibility for termcap output.

      +

      improve error message from tset/reset + when both stderr/stdout are redirected to a file or pipe.

    -

    Other user-visible improvements and new features include:

    +

    Several of the less apparent features deal with translation of + terminfo to termcap (and the reverse), with corresponding checks + by tic:

    • -

      added “-D” option to tic and - infocmp, to show the database locations that it could - use.

      +

      modify check in fmt_entry to handle a + cancelled reset string. Make similar fixes in other parts of + dump_entry.c and tput.c

    • -

      added “-s” option to toe, to sort - its output.

      +

      correct read of terminfo entry in which all strings are + absent or explicitly cancelled. Before this fix, the result + was that all were treated as only absent.

    • -

      extended “-c” and - “-n” options of infocmp to allow - comparing more than two entries.

      +

      modify infocmp to suppress + mixture of absent/cancelled capabilities that would only show + as “NULL, NULL”, unless the + “-q” option is used, e.g., to show + “-, @” or “@, + -”.

    • -

      modified toe's report when “-a” - and “-s” options are combined, to - add a column showing which entries belong to a given - database.

      +

      correct a warning from tic + about keys which are the same, to skip over missing/cancelled + values.

    • -

      modified the clear program to take into account the - “E3” extended capability to clear - the terminal's scrollback buffer.

      +

      add check in tic for use of + bold, etc., video attributes in the color capabilities, + accounting whether the feature is listed in + ncv.

      • -
    -

    Examples

    +
  • +

    add check in tic for + unnecessary use of “2” to denote a + shifted special key.

    +
    • -

    Along with the library and utilities, many improvements were - made to the ncurses-examples. - Some were made to allow building (and comparison-testing) against - NetBSD curses and PDCurses. Both lack some of the X/Open Curses - features, necessitating customization. But this activity was - useful because it showed some remaining performance issues (which - have been resolved in this release).

    +
  • +

    improve check in tic for + delays by also warning about beep/flash when a delay is not + embedded, or if those use the VT100 reverse video escape + without using a delay.

    +
    • -

    These changes were made to verify compatibility or compare - performance of ncurses:

    +
  • +

    improve checks in trim_sgr0, comp_parse.c and + parse_entry.c, for cancelled string capabilities.

    +
    • -
    • -

      made workarounds for compiling test-programs with NetBSD - curses, though it lacks some common functions such as - - use_env.

      +

      add check in tic for some + syntax errors of delays, as well as use of proportional + delays for non-line capabilities.

    • -

      added dots_termcap test-program

      +

      add check in tic for + conflict between ritm, rmso, + rmul versus sgr0.

    • -

      added dots_curses test-program, for comparison with the - low-level examples.

      +

      add check in _nc_parse_entry for invalid + entry name, setting the name to + “invalid” to avoid problems storing + entries.

    • -

      added test_setupterm test-proram to demonstrate - normal/error returns from the setupterm and restartterm - functions.

      +

      improve _nc_tparm_analyze, using that to + extend the checks made by tic + for reporting inconsistencies between the expected number of + parameters for a capability and the actual.

    • -

      added “-d”, - “-e” and - “-q” options to the demo_terminfo - and demo_termcap test-programs.

      +

      remove tic warning about + “^?” in string capabilities, which + was marked as an extension; however all Unix implementations + support this and X/Open Curses does not address it. On the + other hand, + BSD termcap did not support this feature (until the + + mid-1990s).

      + +

      in _nc_infotocap, added a check to ensure + that terminfo “^?” is not written to + termcap.

    • -

      added “-y” option to demo_termcap - and test/demo_terminfo test-programs to demonstrate behavior - with/without extended capabilities.

      +

      modify sscanf calls in + _nc_infotocap for patterns + “%{number}%+%c” and + “%'char'%+%c” to check that the + final character is really “c”, + avoiding a case in icl6404 which cannot be converted to + termcap.

    • -

      modified demo_termcap and demo_terminfo test-programs to - make their options more directly comparable, and add - “-i” option to specify a terminal - description filename to parse for names to lookup.

      +

      in _nc_tic_expand and + _nc_infotocap, improved string-length check when + deciding whether to use “^X” or + “\xxx” format for control + characters, to make the output of tic/infocmp + more predictable.

    • -

      rewrote the tests for - mvderwin and test for recursive - mvwin in the movewindow test-program.

      +

      limited termcap “%d” width to 2 + digits on input, and use “%2” in + preference to “%02” on output.

      +
      • + +
    • +

      correct terminfo/termcap conversion of + “%02” and + “%03” into + “%2” and + “%3”; the result repeated the last + character.

    -

    These changes were made to help with the MinGW port:

    +

    Examples

    + +

    Along with the library and utilities, many improvements were + made to the ncurses-examples.

    + +

    These changes were made to demonstrate new extensions in + ncurses:

    • -

      added test-screens to the ncurses test-program to show - 256-characters at a time, to help with MinGW port.

      +

      add demo_new_pair program, + to demonstrate + alloc_pair, + find_pair and + free_pair functions.

      + +

      This program iterates over the possible color + combinations, allocating or initializing color pairs. For + best results, choose screen-width dividing evenly into the + number of colors. e.g.,

      + +
      + + + + + + + + + + + + + + + + + + +
      32x64,32x128  256 colors
      24x44,24x8888 colors
      32x64,24x12816 colors
      +
    • -

      modified the view test-program to load UTF-8 when built - with MinGW by using regular win32 API because the MinGW - functions mblen and mbtowc do not work.

      +

      add extended_color program, + like the older color_set + program, but using the extended color functions, with and + without the SP-functions interface.

    • -

      added “-s” option to the view - test-program to allow it to start in single-step mode, - reducing size of trace files when it is used for debugging - MinGW changes.

      +

      add picsmap program to fill + in some testing issues not met by dots, using this as the third example in a + comparison of the + ncurses versus slang libraries.

      + +

      The program can directly read X bitmap and pixmap files, + displaying a picture. It can read other image files using + ImageMagick's convert program to translate the image + into text.

      + +

      For 16-, 88- and 256-color terminal descriptions, + picsmap can load a palette + file which tells it which color palette entries to use. For + direct-colors, the terminal descriptions use the + RGB extension capability.

    -

    These changes were made to verify new extensions in ncurses:

    +

    There are other new example programs and a few scripts:

    • -

      added - form_driver_w entrypoint to wide-character forms library, - as well as form_driver_w test-program.

      +

      add dots_xcurses program to + illustrate a different approach used for extended colors + which can be contrasted with dots_curses.

    • -

      modified ncurses test-program's b/B tests to display lines - only for the attributes which a given terminal supports, to - make room for an italics test.

      +

      add list_keys program show + function keys for one or more terminal descriptions. It uses + ncurses's convention of + modifiers for special keys, based on xterm.

    • -

      modified ncurses test-program, adding - “-E” and - “-T” options to demonstrate use_env - versus use_tioctl.

      +

      add padview program, to + compare pads with direct updates in the view program.

    • -

      modified ncurses test-program's c/C tests to cycle through - subsets of the total number of colors, to better illustrate - 8/16/88/256-colors by providing directly comparable - screens.

      +

      add sp_tinfo program to + exercise the SP-functions extension of the low-level terminfo + library.

    • -

      modified the ncurses test-program to also show position - reports in 'a' test.

      +

      add test-programs for termattrs and + term_attrs functions.

      • -
    - -

    These changes were made to make the examples more useful:

    -
    • -

      added scripts for building dpkg and rpm test-packages

      +

      add test_sgr program to + exercise all combinations of the sgr capability.

    • -

      modified the hanoi test-program to show the minimum number - of moves possible for the given number of tiles.

      +

      add tput-colorcube demo + script, imitating xterm's 88- and 256-color scripts using + tput.

    • -

      modified the knight test-program to show the number of - choices possible for each position in automove option, e.g., - to allow user to follow Warnsdorff's rule to solve the - puzzle.

      +

      add tput-initc script to + demonstrate how tput may be + used to initialize a color palette from a data file.

    -

    Terminal - database

    +

    A variety of improvements were made to existing programs, both + new features as well as options added to make the set of programs + more consistent.

    -

    This release provides improvements to tic's - “-c” checking option, which was used for - example to

    +

    The ncurses program is the + largest; a proportionately large number of changes were made to + it:

    • -

      make sgr in several entries agree with other - caps.

      +

      modify a/A screens to make exiting on an escape character + depend on the start of keypad and timeout modes, to allow + better testing of function-keys.

      + +

      add “t” toggle for + notimeout function.

    • -

      correct padding in some entries where earlier versions had - miscounted the number of octal digits.

      +

      modify layout of b/B screens to allow for additional + annotation on the right margin; some terminals with partial + support did not display well.

      • -
    -

    There are several new terminal descriptions:

    - -
      -
    • - mlterm is now aliased to mlterm3
      • - -
    • - nsterm is now derived from nsterm-256color
      • - -
    • - putty-sco
      • +
    • +

      modify c/C screens to allow for extended color pairs.

      -
    • - teken is FreeBSD's "xterm" console.
      • +

      add z/Z zoom feature to make extended color pairs + easier to test.

      -
    • - terminator
      • +

      modify test-screens to take advantage of wide screens, + reducing the number of lines used for 88- and 256-colors.

      + -
    • - terminology
      • +
    • +

      modify “d” edit-color screen to + optionally read xterm color palette directly from terminal, + as well as handling KEY_RESIZE and + screen-repainting with control/L and control/R.

      +
      • -
    • - tmux is derived from screen.
      • +
    • +

      add examples to “F” screen for + WACS_D_PLUS and WACS_T_PLUS.

      +
      • -
    • several screen.XXX entries support the respective - variations for 256 colors.
      • +
    • +

      improve “g” screen, correcting + ifdef which made the legend not reflect changes to keypad- + and scroll-modes. Added check for return-value of + putwin.

      +
      • -
    • - simpleterm is now 0.5
      • +
    • +

      make “s” test easier to + understand which subtests are available

      -
    • - vte is aliased to vte-2012

      • +
    • +

      add “v” screen to show + baudrate and other values.

      +
    -

    A few entries use extensions (user-defined terminal - capabilities):

    +

    These changes were made to the other examples:

    • -

      E3, used in linux, putty and xterm-basic is - tested in the clear - program to erase a terminal's scrollback.

      +

      modify blue program to use + Unicode values for card-glyphs when available, as well as + improving the check for CP437 and CP850.

    • -

      TS is used in the - xterm+sl building block to help deprecate the misuse of - tsl for xterm's title-string.

      +

      improve demo_menus program, + allowing mouse-click on the menu-headers to switch the active + menu. This requires a new extension option + O_MOUSE_MENU to tell the menu driver to put + mouse events which do not apply to the active menu back into + the queue so that the application can handle the event.

    • -

      XT is used in some terminfo entries to - improve usefulness for other applications than screen, which - would like to pretend that xterm's title is a - status-line.

      +

      correct logic in demo_terminfo program for + “-f” option

    • -

      xm is used in examples - xterm-1005 and - xterm-1006 to illustrate a way to make mouse handling - more general

      +

      modify ditto program to + allow $XTERM_PROG environment variable to + override "xterm" as the name of the program to run in the + threaded configuration.

      • -
    -

    A few terminals support italics and/or dim capabilities. In - particular, screen does not. Documented that, and accommodated - the terminals where this feature works with the - A_ITALIC extension.

    +
  • +

    add several options to the “dots” + test-programs.

    +
    • -
      -
    • konsole, mlterm3 (italics)
      • +
    • +

      modify filter program:

      + +
        +
      • illustrate an alternative to getnstr, that + polls for input while updating a clock on the right margin + as well as responding to window size-changes.
        • + +
      • adapt logic used in dialog + “--keep-tite” option for + filter program as the "-a" + option. When set, filter + attempts to suppress the alternate screen.
        • +
      +
      • -
    • nsterm (dim)
      • +
    • +

      modify knight program to + provide the "slow" solution for small screens using + “R”, noting that Warnsdorf's method + is easily done with “a”.

      +
      • -
    • screen (dim)
      • +
    • +

      modify the savescreen + program to add test patterns that exercise 88-, 256-, etc., + colors.

      +
    • expand tabs using the ncurses library rather than in + the test-program.
      • -

      As usual, this release

      +
    • eliminate the “-n” option by + simply reading the whole file.
      • + +
    • implement page up/down commands.
      • + +
    • remove the very old SIGWINCH example; just + use KEY_RESIZE.

    Interesting - bug-fixes

    +

    Terminal + database

    + +

    There are several new terminal descriptions:

    + +
    +

    dumb-emacs-ansi, dvtm, + dvtm-256color, fbterm, + iterm2, linux-m1 minitel + entries, putty-noapp, viewdata, + and vt100+4bsd building-block.

    + +

    xterm+noalt, xterm+titlestack, + xterm+alt1049, xterm+alt+title + building blocks and xterm+direct, + xterm+indirect, xterm-direct. from + xterm + patch #331.

    + +

    several other “-direct” + descriptions to address the differences of other terminal + emulators versus xterm-direct.

    +
    + +

    There are many changes to existing terminal descriptions. Some + were updates to several descriptions:

      -
    • -

      Ada95 binding:

      +
    • use xterm+sm+1006 in several terminal + descriptions which were validated as supporting the extended + mouse feature for their respective terminal emulators.
      • + +
    • corrected sgr/sgr0 strings in a few cases + reported by tic, making those + correspond to the non-sgr settings where they differ, + but otherwise use ECMA-48 consistently.
      • + +
    • add 0.1sec mandatory delay to flash capabilities + using the VT100 reverse-video control
      • +
    +

    while others affected specific descriptions. These were + retested, to take into account new/undocumented changes by their + developers:

    + +
    +

    iterm, minitel, st, + viewdata, nsterm

    +
    + +

    while these are specific fixes based on user reports, or + warnings from tic:

    + +
    +
    + ansi building blocks
    + +
      -
    • -

      modify makefile rules to ensure that the PIC option is - not used when building a static library

      -
      • +
    • restored rmir/smir in + ansi+idc to better match original + ansiterm+idc, add alias + ansiterm
      • +
    +
    -
  • -

    make Ada95 build-fix for big-endian architectures such - as sparc. This undoes one of the fixes from - 20110319, which added an - “Unused” member to - representation clauses, replacing that with pragmas to - suppress warnings about unused bits.

    -
    • +
    + icl6402
    + +
    +
      +
    • corrected missing comma-separator between string + capabilities in icl6402 and + m2-nam

      • +
    • updated using tack and + SFU with Windows 7 Ultimate.
      • -
    • -

      improve - 20021221 workaround for broken acs, handling a case - where that ACS_xxx character is not in the - acsc string but there is a known - wide-character which can be used.

      -
      • +
    • used ^? for kdch1
      • +
    +
    -
  • -

    modify - init_pair to accept -1's for color value after - - assume_default_colors has been called.

    -
    • +
    + linux
    -
  • -

    add a check in - start_color to limit color-pairs to 256 when extended - colors are not supported.

    • +
    +
      +
    • made linux3.0 entry the default + linux entry
      • + +
    • modify linux2.6 entry to improve + line-drawing so that the linux3.0 entry can be + used in non-UTF-8 mode
      • + +
    • omitted selection of ISO-8859-1 for G0 in enacs + capability from linux2.6 entry, to avoid conflict with the + user-defined mapping. The reset feature uses ISO-8859-1 in + any case.
      • + +
    • modify flash capability for linux + and wyse entries to put the delay between the + reverse/normal escapes rather than after
      • + +
    • modify linux-16color to not mask dim, + standout or reverse with the ncv capability

      propagate error-returns from wresize, i.e., the - internal increase_size and decrease_size functions - through - resize_term.

      -
      • +
    • fixed some inconsistencies in the + pccon* entries
      • -
    • -

      • +
    • add bold to pccon+sgr+acs and + pccon-base
      • -
    • -

      modify resizeterm to always push a - KEY_RESIZE onto the fifo, even if screensize - is unchanged. Modify library to push a - KEY_RESIZE if there was a SIGWINCH, even if - it does not call resizeterm). These changes - eliminate the case where a SIGWINCH is received, but ERR - is returned from wgetch or - wgetnstr because the screen dimensions did - not change.

      -
      • +
    • add keys f12-f124 to pccon+keys
    -

    • -

      fix an old bug in the termcap emulation; - “%i” was ignored in - tparm because the parameters to be - incremented were already on the internal stack.

      -
      • +
    • corrected sgr string, which used + screen's "standout" code rather than the + standard code.
      • -
    • -

      change “%l” behavior in tparm - to push the string length onto the stack rather than - saving the formatted length into the output buffer.

      modify internal recursion in wgetch which - handles cooked mode to check if the call to - wgetnstr returned an error. This can happen - when both nocbreak and nodelay - are set, for instance (see note for 960418).

      -
      • +
    • modify vt100 rs2 string to reset + vt52 mode and scrolling regions
      • -
    • -

    Configuration changes

    +

    In particular,

    -

    Major - changes

    +
      +
    • +

      Since the underlying features for + tset, + tput, and + clear have been better + integrated, the documentation now includes information on how + those tools evolved.

      -

      The ncurses 6.0 configure script - makes changes to the default value of several configure - options, depending on the --with-abi-version option - (i.e., whether its value is “5” or - “6”):

      +

      In addition to explaining the improved integration of the + tools, the manual pages made it easier to see how the tools + are similar and how they are different.

      The configure script no longer checks for antique compilers; - c89 is assumed as a minimum. There are a few - features from later revisions which are used when available. The - configure script makes checks to turn on useful warnings from - clang, gcc and icc. You should be able to build ncurses 6.0 with any of the current (or not so - current) C compilers available in 2015.

      - -

      The configure script, by the way, makes changes which do not - work with systems whose /bin/sh is non-POSIX. This - mainly affects Solaris (the other vendor unix systems have followed the POSIX guidelines - for the past twenty years). If you must build on Solaris, its - xpg4 - binaries suffice, e.g.,

      - -

        improve manual page description of tset/reset + versus window-size.

      • -

      Configuration options

      +

      There are new manual pages:

      -

      There are several new (or extended) configure options:

      +
        +
      • + user_caps documents the terminfo extensions used by + ncurses.
        • -
        -
        --disable-db-install
        +
      • +

        + scr_dump documents the screen-dump format.

        +
        • +
      -
      -

      Do not install the terminal database. This is used to omit - features for packages, as done with - --without-progs. The option simplifies building - cross-compile support packages.

      -
      +

      Some of the improvements are more subtle, relating to the way + the information is presented:

      -
      --disable-gnat-projects
      +
        +
      • +

        Made minor fixes to manpage NAME/SYNOPSIS + sections to consistently use rule that either all functions + which are prototyped in SYNOPSIS are listed in the + NAME section, or the manual-page name is the sole + item listed in the NAME section. The latter is used + to reduce clutter, e.g., for the top-level library manual + pages as well as for certain feature-pages such as + SP-funcs and + threading.

        +
        • -
        -

        +
      • +

        improve organization of the + attributes and color manual + pages.

        +
        • +
      -
      -

      Suppress the “w”, “t” or - “tw” suffixes which normally would be added to - the library names for the --enable-widec and - --with-pthread options.

      -
      +

      Interesting + bug-fixes

      -
      --with-cxx-shared
      +
        +
      • +

        modify toe to not exit if + unable to read a terminal description, e.g., if there is a + permission problem.

        +
        • -
        -

        When --with-shared is set, build libncurses++ - as a shared library. This implicitly relies upon building - with gcc/g++, since other compiler suites may have - differences in the way shared libraries are built. libtool by - the way has similar limitations.

        +
        • +
      -
      --with-pc-suffix
      +

      Configuration changes

      -
      -

      If ".pc" files are installed, optionally add a suffix to - the files and corresponding package names to separate unusual - configurations. If no option value is given (or if it is - "none"), no suffix is added. This option is used in the test - package for ncurses6.

      -
      +

      Major + changes

      -
      --with-xterm-kbs
      +

      This release provides a new binary format for terminal + descriptions that use extended numeric capabilities. Applications + built with the wide-character ncursesw library can use + these extended numbers.

      -
      -

      Configure xterm's terminfo entries to use either BS - (^H, i.e., ASCII backspace) or DEL - (^?, or 127).

      -
      - +
        +
      • +

        This includes utilities such as tic and infocmp, because (as noted in New features), the feature + relies upon an extension to the low-level tinfo + library.

        +
        • -

        Portability

        +
      • +

        A few software packagers use a configuration option of + ncurses which allows the + low-level tinfo library to be shared between the + high-level ncurses and ncursesw libraries. + This new feature was designed to work in that configuration + as well.

        +
        • +
      + +

      Other applications (i.e., using the 8-bit ncurses + library) which read the extended terminal descriptions see those + numeric capabilities set to the maximum value for a signed 16-bit + number.

      -

      MinGW

      +

      Older versions of ncurses' + tic accept out-of-range numeric + capabilities, storing those as the maximum value for a signed + 16-bit number. Other implementations of curses (mentioned in the + discussion of + picsmap) give zero for these + out-of-range capabilities.

      -

      Most of the portability-related work since - ncurses 5.9 extended and improved the MinGW port - introduced in - ncurses 5.8.

      +

      Configuration options

      -

      The MinGW port can be readily cross-compiled:

      +

      These changes provide support for tack 1.08, released in + July 2017:

      • -

        modified configure script to allow creating dll's for - MinGW when cross-compiling.

        +

        add --without-tack configure option to refine + --with-progs configure option. Normally + tack is built outside the + ncurses tree, but a few + packagers combine it during the build. If + term_entry.h is installed, there is no advantage + to in-tree builds.

      • -

        enforced Windows-style path-separator if - cross-compiling,

        +

        adjust configure-script to define + HAVE_CURSES_DATA_BOOLNAMES symbol needed for + tack 1.08 when built in-tree. + Rather than relying upon internal "_nc_" functions, + tack now uses the boolean, + number and string capability name-arrays provided by + ncurses and SVr4 Unix curses. + It still uses term_entry.h for the definitions + of the extended capability arrays.

      • -

        added scripts for test-builds of cross-compiled packages - for ncurses6 to MinGW.

        +

        add dependency upon ncurses_cfg.h to tic's header-files; any program using + tic-library will have to + supply this file. Legacy tack + versions supply this file; ongoing tack development has dropped the + dependency upon tic-library + and new releases will not be affected.

        • +
      + +

      Other changes to the configure-script and generated files + include

      +
      • -

        added pc-files to the MinGW cross-compiling - test-packages.

        +

        add configure options to disable checks for form, menu and + panel libraries so that ncurses-examples can be built with + non-SVr4 curses implementations.

      • -

        added script for building test-packages of binaries - cross-compiled to MinGW using NSIS.

        +

        add configure option --enable-opaque-curses + for ncurses library and similar options for the + other libraries.

      • -

        added nc_mingw.h to installed headers for - MinGW port; this is needed for cross-compiling ncurses-examples.

        +

        add configure option --disable-wattr-macros + for use in cases where one wants to use the same headers for + ncurses5/ncurses6 development, by suppressing the + wattr* macros which differ due to the introduction + of extended colors

      • -

        added test-packages for cross-compiling ncurses-examples - using the MinGW test-packages.

        +

        modify configure macro for shared-library rules to use + -Wl,-rpath rather than -rpath to + work around a bug in scons

        • -
      -

      The MinGW-specific Windows driver accounts for several - changes:

      - -
      • -

        wide-character display is made usable by replacing MinGW's - non-working wcrtomb and wctomb - functions.

        +

        improve ncurses-examples' configure script to define as + needed NCURSES_WIDECHAR for platforms where + _XOPEN_SOURCE_EXTENDED does not work. Also + modified the test program to ensure that if building with + ncurses, that the + cchar_t type is checked, since that is normally + (since 20111030) + ifdef'd depending on this test.

      • -

        implemented some display features: beep, - flash, - - curs_set.

        +

        modify configure script to handle the case where + tic-library is renamed, but + the --with-debug option is used by itself + without normal or shared libraries

      • -

        the driver handles repainting on endwin/refresh - combination.

        +

        modify editing script which generates resulting.map to + work with the clang configuration on recent FreeBSD, which + gives an error on an empty "local" section.

      • -

        modified treatment of TERM variable for MinGW - port to allow explicit use of the Windows console driver by - checking if $TERM is set to - “#win32console” or an abbreviation - of that.

        +

        improve configure check for setting the + WILDCARD_SYMS variable; on ppc64 the variable is + in the Data section rather than + Text.

      • -

        the Windows driver also matches the special - TERM value “unknown”

        +

        correct result of configure option + --without-fallbacks, which caused FALLBACK_LIST + to be set to "no"

      • -

        the driver now returns characters for special keys, (like - ansi.sys does), when keypad mode is off, rather - than returning nothing at all.

        +

        modify --with-pkg-config-libdir option to + make it possible to install “.pc” files even if + pkg-config is not found. Limit + this change, to suppress the actual install if it is not + overridden to a valid directory at install time.

      • -

        the driver checks a new environment variable - NCURSES_CONSOLE2 to optionally work around a deficiency - in Console2 (and its descendent - ConsoleZ) which hang when an application creates - a console buffer.

        +

        disallow “no” as a possible value for + --with-shlib-version option, overlooked in + cleanup-changes for 20000708.

      -

      Finally, there are other improvements:

      +

      Portability

      + +

      Many of the portability changes are implemented via the + configure script:

      • -

        MinGW is one of the configurations where ncurses installs by default into /usr

        +

        improve configure script's CF_CC_ENV_FLAGS + macro to allow for compiler wrappers such as ccache. This change moves only the + preprocessor, optimization and warning flags to + CPPFLAGS and CFLAGS, leaving the + residue in CC. That happens to work for + gcc's various + “model” options, but may require tuning for other + compilers.

        • -
      • configuration for cross-compiling uses AC_CHECK_TOOLS in - preference to AC_PATH_PROGS when searching for ncurses*-config, - e.g., in Ada95/configure and test/configure.
        • -
      • -

        extend Windows support to work with MSYS2;

        - -
          -
        • -

          this works with a scenario where there is an - ANSI-escape handler such as ansicon running - in the console window.

          -
          • - -
        • wrap isatty calls with a macro, provide a - corresponding set of support routines to address - differences between MinGW and MSYS2.
          • -
        +

        modify ncurses-examples' configure script to use + pkg-config for the extra + form/menu/panel libraries, to be more consistent with the + handling of the curses/ncurses library.

      • -

        ensure WINVER is defined in makefiles rather - than using headers.

        +

        add configuration checks to build with NetBSD + curses, which for example lacks + use_env.

      • -

        add check for the gnatprep - “-T” option.

        +

        change ncurses-examples to use attr_t vs + chtype to follow X/Open documentation more + closely since Solaris xpg4-curses uses different values for + WA_xxx vs A_xxx + that rely on attr_t being an unsigned short. Tru64 aka OSF1, + HPUX, AIX did as ncurses does, + equating the two sets.

      • -

        work around a bug introduced by - gcc 4.8.1 in MinGW which breaks "trace" feature.

        +

        modify several test programs to reflect that ncurses honors existing signal handlers in + initscr, while other implementations do not.

      • -

        add a driver-name method to each of the drivers.

        +

        add configure check for openpty to + ncurses-examples' configure script, for ditto.

        • -
      - -

      Other - ports

      -

      These changes affect certain platforms (ports):

      +
    • +

      improve check for working poll function by + using posix_openpt as a fallback in case there + is no valid terminal on the standard input

      +
      • -
      • -

        the configure script knows how to build shared libraries - with DragonFlyBSD and Interix.

        +

        modify ncurses-examples' configure script to check for + pthread dependency of + ncursest or ncursestw library when building + the ncurses examples, e.g., in + case weak symbols are used.

      • -

        support for AIX shared libraries is improved, tested with - AIX 5.3, 6.1 and 7.1 with both gcc 4.2.4 and cc:

        +

        add checks in ncurses-examples' configure script for some + functions neither in 4.3BSD curses, nor based on X/Open + Curses:

        • -

          the shared-library suffix for AIX 5 and 6 is now - ".so"

          +

          modify a loop limit in firework.c to work around + absense of limit checks in some libraries.

        • -

          the -brtl option is used with AIX 5-7; it - is needed to link with the shared libraries.

          +

          fill the last row of a window with + “?” in firstlast if waddch does + not return ERR on the lower-right + corner.

      • -

        the configure --enable-pc-files option takes - into account the PKG_CONFIG_PATH - variable.

        -

        • -

          the build scripts add explicit -ltinfo, etc., to the - generated ".pc" file when ld option - “--as-needed” is used, or when - ncurses and tinfo are installed without using rpath.

          +
        • +

          +
          • + +
        • +

          add configure check for -fPIC option needed for shared + libraries.

          +
          • +
      • -

        the configure script disallows conflicting options - “--with-termlib” and - “--enable-term-driver”.

        +

        modify configure script for clang as used on FreeBSD, to + work around clang's differences in exit codes vs gcc.

      • -

        the check for missing c++ compiler to work when no error - is reported, and no variables set is improved (see note for - 20021206).

        +

        fixes for configure/build using clang on OSX

        + +
          +
        • +

          do not redefine “inline” in + ncurses_cfg.h; this was originally to solve + a problem with gcc/g++, but is aggravated by clang's + misuse of symbols to pretend it is gcc.

          +
          • + +
        • +

          add braces to configure script to prevent unwanted + addition of “-lstdc++” option to + the CXXLIBS symbol.

          +
          • + +
        • +

          +
          • + +
        • +

          if $CXXLIBS is set, the linkage test uses + that in addition to $LIBS.

          +
          • +
      • -

        the test/configure script makes it simpler to override - names of curses-related libraries, to help with linking with - pdcurses in MinGW environment.

        +

        add “newer” baudrate symbols to the + baudrate function in the ncurses library as + well as to a corresponding table in tset.

      • -

        the configure-script/ifdef's allow the BSD OLD_TTY feature - to be suppressed if the type of ospeed is - configured using the option --with-ospeed to not - be a short. By default, it is a - short for termcap-compatibility.

        +

        modify ncurses-examples savescreen to work with AIX and HPUX.

      • -

        the MKlib_gen.sh script works around a recent change in - gcc 5 (released mid-2015) which essentially - emits multiple #line statements for the same - position in a file.

        +

        define WIN32_LEAN_AND_MEAN for MinGW port, + making builds faster.

      • -

        the configure script works with Minix3.2 (see note - on portability)

        +

        add a configure check for wcwidth versus the + ncurses line-drawing + characters, to use in special-casing systems such as Solaris. + Solaris, however, requires a special case that maps Unicode + line-drawing characters into the acsc string for non-Unicode + locales. Solaris also has a misconfigured wcwidth which marks + all of the line drawing characters as double-width.

    These notes are for ncurses + 6.1, released January 27, 2018.

    This release is designed to be source-compatible with - ncurses 5.0 through 5.9; providing a - new application binary interface (ABI). Although the source can - still be configured to support the ncurses 5 ABI, the intent of the release is to - provide extensions which are generally useful, but - binary-incompatible with ncurses - 5:

    + ncurses 5.0 through 6.0; providing + extensions to the application binary interface (ABI). Although + the source can still be configured to support the ncurses 5 ABI, the intent of the release is to + provide extensions to the ncurses + 6 ABI:

    • -

      Extend the cchar_t structure to allow more - than 16 colors to be encoded.

      +

      improve integration of tput + and tset

    • -

      Modify the encoding of mouse state to make room for a 5th - mouse button. That allows one to use ncurses with a wheel mouse with xterm or - similar X terminal emulators.

      +

      provide support for extended numeric capabilities.

    There are, of course, numerous other improvements, listed in + this announcement.

    + +

    The release notes also mention some bug-fixes, but are focused + on new features and improvements to existing features since + ncurses 6.0 release.

    + +

    Library + improvements

    + +

    New + features

    + +

    The improved integration of tput and tset + made only small changes to the libraries. However, supporting + extended numeric capabilities required a few changes:

    • -

      fixes made based on the Clang and Coverity static - analyzers.

      +

      The TERMINAL structure in + <term.h> is now opaque. Doing that allowed + making the structure larger, to hold the extended numeric + data.

      + +

      A few applications required changes during development of + ncurses 6.1 because those + applications misused the members of that structure, e.g., + directly modifying it rather than using + def_prog_mode.

    • -

      memory leak fixes using Valgrind

      -
      • -
    +

    Having made TERMINAL opaque (and because none + of the library functions use anything except a pointer to + TERMINAL), it was possible to increase the size + of the structure, adding to the end.

    -

    The release notes mention some bug-fixes, but are focused on - new features and improvements to existing features log since - ncurses 5.9 release.

    +

    Existing applications which were linked to the + ncurses 6.0 high-level + (ncurses, ncursesw) and low-level + (tinfo, tinfo) libraries should not require + re-linking since the binary interface did not change, nor did + the structure offsets with TERMINAL change.

    -

    While the intent of the release is to provide a new stable - ABI, there are other development activities which are summarized - below.

    +

    A few applications use the inner TERMTYPE + structure's offsets to refer to terminfo capabilities within + that structure. Again, those do not require modification + because their offsets within TERMINAL did not + change.

    + -
    • -

      The original release plan, e.g., for "5.10" was to improve - the MinGW port. Ultimately that was completed (wide-character - support, mouse, etc), but was deferred to focus on termcap - support and performance issues. Also, pinpointing the - problems with Console2 took a while.

      +

      When configured for wide-characters, i.e., + “ncursesw” the TERMINAL structure is + extended.

      + +

      The new data in TERMINAL holds the same + information as TERMTYPE, but with larger numbers + (“int” versus “short”). It is named + TERMTYPE2.

      + +

      The library uses this structure internally in preference + to TERMTYPE, referring to TERMTYPE + only to initialize it for applications that use the + capabilities defined in <term.h>

    • -

      A review of termcap compatibility in 2011 led to several - minor fixes in the library and improvements to utilities. To - do this properly, a review of the various extent termcap - implementations was needed.

      +

      When configured for 8-bit (narrow) characters, the + TERMTYPE2 structure is not used.

      +
      • -

      The termcap - library checker (tctest) (not part of ncurses) was one result. A followup review - of performance using ncurses-examples - in 2014 led to additional improvements.

      +
    • The updated application binary interface is 6.1.20171230 + (used for new versioned + symbols), although the interface changes were developed + several months previously.
      • +
    + +

    The motivation for making this extension came from noticing + that + termcap applications could (though not + realistically) use larger numbers than would fit in 16-bits, + and the fact that the number of color pairs for a 256-color xterm + could not be expressed in terminfo (i.e., 32767 versus 65536). + Also, a few terminals support direct-colors, which could use the + extension.

    + +

    Generally speaking, applications that use internal details of + a library are unsupported. There was exactly one exception for + ncurses: the tack program used the internal + details of TERMINAL, because it provides an + ncurses-specific feature for interactively modifying a terminfo + description and writing the updated description to a text-file. + It was possible to not only separate tack from these internal + details of ncurses, but to + generalize it so that the program works with Unix curses + (omitting the ncurses-specific feature). That was released as + + tack 1.08 in July + 2017.

    + +

    While making changes to tack to + eliminate its dependency upon ncurses internals, the publicly-visible + details of those internals were reviewed, and some symbols were + moved to private header files, while others were marked + explicitly as ncurses internals. + Future releases of ncurses may + eliminate some of those symbols (such as those used by + tack 1.07) because they are + neither part of the API or the ABI.

    + +

    Using the TERMTYPE2 extended numeric + capabilities, it is possible to support both color pair values + and color values past 32767. Taking compatibility into account, + developers readily understand that neither function signatures + nor structure offsets change. Also, existing functions have to + operate with the extended numbers. Most of that work is internal + to the library. For the external interfaces, a hybrid approach + was used:

    + +
      +
    • +

      X/Open Curses defined function prototypes such as + wattr_set with an unused parameter, for + “future” use. After 25 years, the future is here: + ncurses uses the parameter to + augment color pair values as described in the + manual page.

    • -

      Output buffering provided a further, but worthwhile - distraction. A bug report in 2012 regarding the use of signal - handlers in ncurses) pointed out - - a problem with the use of unsafe functions for handling - SIGTSTP. Other signals could be addressed with - workarounds; repairing SIGTSTP required a - different approach. The solution required changing internal - behavior of the library: how it handles output buffering.

      - -

      Now ncurses buffers its own - output, independently of the standard output. A few - applications relied upon the library's direct reuse of the - standard output buffering; however that is - unspecified behavior and has never been a - recommended practice. Identifying these applications as well - as refining the change to permit low-level applications to - work consistently took time.

      -
      • - -
    • -

      Since the introduction of the experimental support for 256 - colors early in 2005 - (released in ncurses - 5.5), there has been increased user interest. Almost all - packagers continue providing the ncurses ABI 5 which cannot - support 256 colors.

      -
      • - -
    • -

      Symbol versioning, or the lack of it in ncurses, is the - main reason why packagers would be reluctant to add a new - ncurses ABI.

      - -

      This release provides the new ABI along with - script-generated lists of versioned symbols which can be used - for both ABI 5 and 6 (with distinct names to keep the two - separate). This took time to development, as reported in - Symbol - versioning in ncurses.

      +

      Other functions such as those defining color pairs did not + have a corresponding reserved parameter. For those, + ncurses defines extended + versions such as init_extended_pair (versus + init_pair), init_extended_color + (versus init_color).

    -

    Library - improvements

    +

    Additionally, to improve performance other changes (and + extensions) are provided in this release:

    -

    Output - buffering

    +
      +
    • +

      Several new functions simplify management of large sets of + color pairs: reset_color_pairs, + alloc_pair, find_pair and + free_pair.

      +
      • -

      X/Open curses provides more than one initialization - function:

      +
    • +

      New "RGB" extension capability for direct-color support is + used to improve performance of + color_content.

      +
      • -
        -
      • - initscr (the simplest) accepts no parameters.
        • +
      • +

        The internal colorpair_t is now a struct, + eliminating an internal 8-bit limit on colors

        +
        • -
      • - newterm accepts parameters for the stream input and - output
        • +
      • +

        Allocation for SCREEN's color-pair table + starts small, grows on demand up to the limit given in the + terminal description.

        +
        • -
      • - setupterm (the low-level function) accepts a parameter for - the file descriptor of the output.
        • +
      • +

        setcchar and getcchar now treat + a negative color-pair as an error.

        +
      -

      They are documented in X/Open as if - initscr calls newterm using - stdout for output stream, and in turn - newterm calls setupterm using - fileno(stdout) for the file descriptor. As long as - an implementation acts as if it does this, it conforms. - In practice, implementations do what is implied. This creates a - problem: the low-level setupterm function's file - descriptor is unbuffered, while newterm implies - buffered output. X/Open Curses says that all output is done - through the file descriptor, and does not say how the output - stream is actually used.

      - -

      Initially, ncurses used the file - descriptor (obtained from the output stream passed to - newterm) for changing the terminal modes, and relied - upon the output parameter of newterm for buffered - output. Later (to avoid using unsafe buffered I/O in signal - handlers), ncurses was modified to - use the file descriptor (unbuffered output) when cleaning up on - receipt of a signal. Otherwise (when not handling a signal), it - continued to use the buffered output.

      - -

      That approach worked reasonably well and as a side effect, - using the same buffered output as an application might use for - printf meant that no flushing was needed when - switching between normal- and screen-modes.

      - -

      There were a couple of problems:

      +

      Other + improvements

      + +

      These are new or revised features:

      • -

        to get good performance, curses (not only ncurses, but SVr4 curses in general) set an - output buffer using setbuf or similar function. - There is no standard (or portable) way to turn that output - buffer off, and revert to line-buffering. The - NCURSES_NO_SETBUF environment variable did make it - optional.

        +

        modify c++/etip.h.in to accommodate + deprecation of throw and throws in c++17

      • -

        to handle SIGTSTP (the “stop” - signal), ncurses relied upon - unsafe functions. That is, due to the complexity of the - feature, it relied upon reusing existing functions which - should not have been called via the signal handler.

        +

        add new function unfocus_current_field

        • -
      -

      Conveniently, solving the second problem (by making ncurses do its own output buffering) - also fixed the first one. But there were special cases to - resolve: - low-level functions such as mvcur, putp, vidattr - explicitly use the standard output. Those functions were reused - internally, and required modification to distinguish whether they - were used by the high-level or low-level interfaces.

      +
    • +

      add option to preserve leading whitespace in form + fields

      +
      • -

      Finally, there may still be a few programs which should be - modified to improve their portability, e.g., adding an

      +
    • +

      add a macro for is_linetouched and adjust the + function's return value to make it possible for most + applications to check for an error-return.

      +
      • -
      - 
      -fflush(stdout);
-
      -
      +
    • +

      add build-time utility report_offsets to help + show when the various configurations of tinfo library are + compatible or not.

      +
      • +
    -

    when switching from “shell” - mode to “program” - (curses) mode. Those are fairly rare because most programmers - have learned not to mix printf and printw.

    - -

    Symbol - versioning

    - -

    This release introduces symbol-versioning to ncurses because without it, the change of ABI - would be less successful. A lengthy discussion will be presented - in Symbol - versioning in ncurses. These - notes summarize what has changed, and what can be done with the - new release.

    - -

    Symbol-versioning allows the developers of a library to mark - each public symbol (both data and functions) with an identifier - denoting the library name and the version for which it was built. - By doing this, users of the library have a way to help ensure - that applications do not accidentally load an incompatible - library. In addition, private symbols can be hidden entirely.

    - -

    This release provides sample files for the four principal - configurations of ncurses libraries: - ncurses, ncursesw, - ncursest and ncursestw. Each sample is - given in two forms:

    +

    These were done to limit or ultimately deprecate features:

    -
    -
    -
    “.map”
    +
      +
    • +

      drop two symbols obsoleted in 2004: + _nc_check_termtype, and + _nc_resolve_uses

      +
      • -
      These list all public symbols, together with version - names.
      +
    • +

      move _nc_tracebits, _tracedump + and _tracemouse to curses.priv.h, + since they are not part of the suggested ABI6.

      +
      • -
      “.sym”
      +
    • +

      mark some structs in form/menu/panel libraries as + potentially opaque without modifying API/ABI.

      +
      • -
      These list all public symbols, without version - names.
      -
    -
    +
  • +

    ifdef'd header-file definition of mouse_trafo + with NCURSES_NOMACROS

    +
    • -

    The sample files are generated by scripts which take - into account a few special cases such as tack to omit - many of the ncurses private symbols - (beginning with “_nc_”). Here are - counts of globals versus locals:

    +
  • +

    remove initialization-check for calling napms + in the term-driver configuration; none is needed.

    +
    • -
    - - - +
  • +

    modify trace to avoid overwriting existing + file

    +
    • + - +

    These are improvements to existing features:

    - +
      +
    • +

      modify make_hash to allow building with + address-sanitizer, assuming that --disable-leaks + is configured.

      +
      • -
    +
  • +

    move SCREEN field for use_tioctl + data before the ncursesw fields, and limit that to the + sp-funcs configuration to improve termlib compatibility

    +
    • - - +
  • +

    modify db-iterator:

    -
    • - +
      +
    • +

      ignore zero-length files in db-iterator; these are + useful for instance to suppress + $HOME/.terminfo when not wanted.

      +
      • -
    +
  • +

    modify update_getenv to ensure that + environment variables which are not initially set will be + checked later if an application happens to set them

    +
    • + + - +
  • +

    modify _nc_outc_wrapper to use the standard + output if the screen was not initialized, rather than + returning an error.

    +
    • - +
  • +

    improve checks for low-level terminfo functions when the + terminal has not been initialized.

    +
    • - - +
  • +

    modify set_curterm to update + ttytype[] data used by longname/p>

    +
    • - - +
  • +

    modify _nc_get_screensize to allow for + use_env and use_tioctl state to be + per-screen when sp-funcs are configured, better matching the + behavior when using the term-driver configuration.

    +
    • - +
  • +

    remove an early-return from _nc_do_color, + which can interfere with data needed by bkgd + when ncurses is configured + with extended colors

    +
    • - +
  • +

    incorporate A_COLOR mask into + COLOR_PAIR, in case user application provides an + out-of-range pair number

    +
    • - +
  • +

    modify logic for endwin-state to be able to + detect the case where the screen was never initialized, using + that to trigger a flush of ncurses' buffer for mvcur, + e.g., in the sample program dots_mvcur for the term-driver + configuration.

    +
    • + - - +

    These are corrections to existing features:

    - - +
      +
    • +

      fixes for writing extended color pairs in + putwin.

      +
      • -
    +
  • +

    modify no-leaks code for lib_cur_term.c to + account for the tgetent cache.

    +
    • - +
  • +

    amend handling of the repeat_char capability + in EmitRange to avoid scope creep: translate the + character to the alternate character set when the alternate + character set is enabled, and do not use + repeat_char for characters past 255.

    +
    • - +
  • +

    improve wide-character implementation of + myADDNSTR in frm_driver.c, which + was inconsistent with the normal implementation.

    +
    • - - +
  • +

    modify winnstr and winchnstr to + return error if the output pointer is null, as well as adding + a null pointer check of the window pointer for better + compatibility with other implementations.

    +

    Although only four sample configurations are presented, each - is formed by merging symbols from several combinations of - configure-script options, taking into account advice from - downstream packagers. Because they are formed by merging, the - sample files may list a symbol which is not in a given package. - That is expected.

    Program + improvements

    -

    As a special case, this release (which makes the final change - for ABI 5) is marked with release version 5.9 and patch date - 20150530.

    +

    While reviewing user feedback, it became apparent that the + differences between + reset (an alias for + tset) and “tput reset” were confusing:

    -

    Miscellaneous

    +
      +
    • one (tset) + updated the terminal modes, but used only part of the terminfo + capabilities for initialization, while
      • + +
    • the other (tput) + used all of the terminal capabilities while neglecting the + terminal modes.
      • +
    -

    The new release has several improvements for performance and - building. For instance:

    +

    On further investigation, it turned out that the differences + were largely an accident due to the way those programs had + evolved.

    + +

    This release eliminates the unnecessary differences, using the + same approach for tput's + init (initialization), reset and clear + operations as the separate + reset and + clear programs. Doing this does not change the + command-line options; existing scripts are unaffected.

    + +

    These are the user-visible changes for the three programs + (tput, tset and clear):

    • -

      several files in ncurses- and progs-directories were - modified to allow const data used in internal - tables to be put by the linker into the readonly text - segment.

      +

      add the terminal-mode parts of “reset” (aka tset) to the “tput + reset” command, making the two almost the same + except for window-size.

    • -

      various improvements were made to building the Ada95 - binding, both in simplifying the generated files as well as - improving the way it uses gnatmake

      +

      improve tput's check for + being called as “init” or “reset” to + allow for transformed names.

      • -
    -

    There are also new features in the libraries:

    +
  • +

    add “clear” as a possible link/alias to + tput.

    +
    • -
      -
    • added - use_tioctl function
      • +
    • +

      amend changes for tput to + reset tty modes to “sane” if the program is run + as “reset”, like tset. Likewise, ensure that tset sends either reset- or + init-strings.

      +
    • -

      added - wgetdelay to retrieve _delay member of WINDOW if it - happens to be opaque, e.g., in the pthread configuration.

      +

      add -x option to clear/tput + to make the E3 extension optional

    • -

      added - A_ITALIC extension.

      +

      add functionality of + “tset -w” to tput, like the + “-c” feature this is not optional in + tput.

    • -

      added form library extension - O_DYNAMIC_JUSTIFY option which can be used to override - the different treatment of justification for static versus - dynamic fields .

      +

      add options -T and -V to + clear command for + compatibility with tput.

    • -

      rewrote - putwin and - getwin, making an extended version which is capable of - reading screen-dumps between the wide/normal ncurses configurations. These are text - files, except for a magic code at the beginning:

      +

      drop long-obsolete “-n” option + from tset.

      +
      • -
      - 
      -0       string          \210\210        Screen-dump (ncurses)
-
      -
      +
    • +

      modify tset's assignment to + TERM in its output to reflect the name by which + the terminal description is found, rather than the primary + name. That was an unnecessary part from the initial + conversion of tset from + termcap to terminfo. The termcap library in 4.3BSD did this + to avoid using the short 2-character name

    • -

      several changes to mouse support include:

      +

      remove a restriction in tput's support for termcap names which + omitted capabilities normally not shown in termcap + translations

      +
      • + +
    • +

      add usage message to clear + command

      +
      • + +
    • +

      improve usage messages for tset and tput.

      +
      • +
    + +

    Other user-visible improvements and new features include:

    + +
      +
    • +

      modify tic/infocmp display of numeric values to use + hexadecimal when they are "close" to a power of two, making + the result more readable.

      +
      • + +
    • +

      add “-W” option to tic/infocmp + to force long strings to wrap.

        -
      • added decoder for xterm SGR 1006 mouse mode.
        • +
      • +

        This is in addition to the + “-w” option which attempts to + fit capabilities into a given line-length.

        +
        • -
      • added experimental support for - “%u” format to terminfo.
        • +
      • +

        If “-f” option splits line, + do not further split it with + “-W”.

        +
        • -
      • improved behavior of wheel-mice for xterm protocol: - noting that there are only button-presses for buttons - “4” and “5”, so there is no need to - wait to combine events into double-clicks .
        • +
      • +

        Begin a new line when adding + “use=” after a wrapped line.

        +
      • -
    -

    There are a few new configure options dealing with library - customization:

    +
  • +

    add “-q” option to infocmp to suppress the + “Reconstructed from” comment from + the header, and a corresponding option to tic to suppress all comments from the + “tic -I” output.

    +
    • -
    • -

      add “--enable-ext-putwin” - configure option to turn on the extended putwin/getwin. By - default, this is enabled for ABI 6 and disabled with ABI - 5.

      +

      Sorted options in usage message for infocmp, to make it simpler to see unused + letters.

    • -

      add “--enable-string-hacks” - option to control whether strlcat and strlcpy may be used. - Because ncurses already does the - requisite buffer-limit checks, this feature is mainly of - interest to quiet compiler-warnings on a few systems.

      +

      Updated usage message for tic, adding “-0” + option.

    • -

      add configure option - “--with-tparm-arg” to allow - tparm's parameters to be something more likely to be the - same size as a pointer, e.g., intptr_t (again, - the default is set for ABI 6).

      +

      add infocmp/tic “-Q” option, + which allows one to dump the compiled form of the terminal + entry, in hexadecimal or base64:

      + +
        +
      • A “b64:” prefix in the + TERMINFO variable tells the terminfo reader to + use base64 according to RFC-3548 as well as RFC-4648 + url/filename-safe format.
        • + +
      • A “hex:” prefix tells the + terminfo reader to accept hexadecimal data as generated by + “infocmp -0qQ1”.
        • +
    -

    Program - improvements

    - -

    Utilities

    - -

    Most of the termcap-related changes based on development of - tctest - (termcap library checker) are implemented in the tic and - infocmp programs rather than affecting the library. As noted in - the - discussion of tctest, ncurses's ability to translate between terminfo - and termcap formats has been improved at different times, but - subject to feedback from "real" termcap users. There are very few - of those. Nowadays, virtually all termcap users are - using ncurses (or NetBSD, with its - own terminfo library) and their programs are actually using - terminfo rather than termcap data.

    - -

    Still, there are a few. A comment about the translation of the - ASCII NUL character prompted a review:

    +

    Other less-visible improvements and new features include:

    • -

      Both terminfo and termcap store string capabilities as - NUL-terminated strings.

      +

      modify utility headers such as tic.h to make + it clearer which are externals that are used by tack.

    • -

      In terminfo, a \0 in a terminal description - is stored as \200.

      +

      add “reset” to list of programs + whose names might change in manpages due to + program-transformation configure options.

    • -

      There are no (known) terminals which would behave - differently when sent \0 or - \200.

      +

      modify “-T” option of + clear and tput to call use_tioctl to + obtain the operating system's notion of the screensize if + possible.

    • -

      When translating to terminfo format (or displaying a - printable version of an entry using infocmp), ncurses shows \200 as - \0.

      +

      add check in tput for + init/reset operands to ensure those use a terminal.

    • -

      It has done this since 1998 (quoting from the NEWS - file):

      - -
      - 
      -980103
-...
-        + modify _nc_tic_expand() to generate \0 rather than \200.
-...
-        + correct translation of terminfo "^@", to \200, like \0.
-
      -
      +

      modify programs clear, + tabs, tput and tset to pass the actual tty file + descriptor to setupterm rather than the standard output or + error, making padding work.

    • -

      However, the _nc_tic_expand function (which - optionally produces terminfo or termcap format) did not - address this special case for termcap. Even the later 4.4BSD - - cgetstr interprets a \0 literally, ending - that string (rather than using the terminfo - improvement).

      +

      change tset's + initialization to allow it to get settings from the standard + input as well as /dev/tty, to be more effective + when output or error are redirected.

      • -
    -

    As a result of the review, several improvements were made to - ncurses translation to/from termcap - format — and improving the checks made in tic for - consistency of entries. Most of these are not of general - interest, except for two new command-line options for tic and - infocmp:

    - -
    • -

      the “-0” option generates - termcap/terminfo source on a single line.

      +

      amend check in tput, + tabs and clear to allow those to use the + database-only features in cron + if a “-T” option gives a suitable + terminal name.

    • -

      the “-K” option provides stricter - BSD-compatibility for termcap output.

      +

      improve error message from tset/reset + when both stderr/stdout are redirected to a file or pipe.

    -

    Other user-visible improvements and new features include:

    +

    Several of the less apparent features deal with translation of + terminfo to termcap (and the reverse), with corresponding checks + by tic:

    • -

      added “-D” option to tic and - infocmp, to show the database locations that it could - use.

      +

      modify check in fmt_entry to handle a + cancelled reset string. Make similar fixes in other parts of + dump_entry.c and tput.c

    • -

      added “-s” option to toe, to sort - its output.

      +

      correct read of terminfo entry in which all strings are + absent or explicitly cancelled. Before this fix, the result + was that all were treated as only absent.

    • -

      extended “-c” and - “-n” options of infocmp to allow - comparing more than two entries.

      +

      modify infocmp to suppress + mixture of absent/cancelled capabilities that would only show + as “NULL, NULL”, unless the + “-q” option is used, e.g., to show + “-, @” or “@, + -”.

    • -

      modified toe's report when “-a” - and “-s” options are combined, to - add a column showing which entries belong to a given - database.

      +

      correct a warning from tic + about keys which are the same, to skip over missing/cancelled + values.

    • -

      modified the clear program to take into account the - “E3” extended capability to clear - the terminal's scrollback buffer.

      +

      add check in tic for use of + bold, etc., video attributes in the color capabilities, + accounting whether the feature is listed in + ncv.

      • -
    -

    Examples

    +
  • +

    add check in tic for + unnecessary use of “2” to denote a + shifted special key.

    +
    • -

    Along with the library and utilities, many improvements were - made to the ncurses-examples. - Some were made to allow building (and comparison-testing) against - NetBSD curses and PDCurses. Both lack some of the X/Open Curses - features, necessitating customization. But this activity was - useful because it showed some remaining performance issues (which - have been resolved in this release).

    +
  • +

    improve check in tic for + delays by also warning about beep/flash when a delay is not + embedded, or if those use the VT100 reverse video escape + without using a delay.

    +
    • -

    These changes were made to verify compatibility or compare - performance of ncurses:

    +
  • +

    improve checks in trim_sgr0, comp_parse.c and + parse_entry.c, for cancelled string capabilities.

    +
    • -
    • -

      made workarounds for compiling test-programs with NetBSD - curses, though it lacks some common functions such as - - use_env.

      +

      add check in tic for some + syntax errors of delays, as well as use of proportional + delays for non-line capabilities.

    • -

      added dots_termcap test-program

      +

      add check in tic for + conflict between ritm, rmso, + rmul versus sgr0.

    • -

      added dots_curses test-program, for comparison with the - low-level examples.

      +

      add check in _nc_parse_entry for invalid + entry name, setting the name to + “invalid” to avoid problems storing + entries.

    • -

      added test_setupterm test-proram to demonstrate - normal/error returns from the setupterm and restartterm - functions.

      +

      improve _nc_tparm_analyze, using that to + extend the checks made by tic + for reporting inconsistencies between the expected number of + parameters for a capability and the actual.

    • -

      added “-d”, - “-e” and - “-q” options to the demo_terminfo - and demo_termcap test-programs.

      +

      remove tic warning about + “^?” in string capabilities, which + was marked as an extension; however all Unix implementations + support this and X/Open Curses does not address it. On the + other hand, + BSD termcap did not support this feature (until the + + mid-1990s).

      + +

      in _nc_infotocap, added a check to ensure + that terminfo “^?” is not written to + termcap.

    • -

      added “-y” option to demo_termcap - and test/demo_terminfo test-programs to demonstrate behavior - with/without extended capabilities.

      +

      modify sscanf calls in + _nc_infotocap for patterns + “%{number}%+%c” and + “%'char'%+%c” to check that the + final character is really “c”, + avoiding a case in icl6404 which cannot be converted to + termcap.

    • -

      modified demo_termcap and demo_terminfo test-programs to - make their options more directly comparable, and add - “-i” option to specify a terminal - description filename to parse for names to lookup.

      +

      in _nc_tic_expand and + _nc_infotocap, improved string-length check when + deciding whether to use “^X” or + “\xxx” format for control + characters, to make the output of tic/infocmp + more predictable.

    • -

      rewrote the tests for - mvderwin and test for recursive - mvwin in the movewindow test-program.

      +

      limited termcap “%d” width to 2 + digits on input, and use “%2” in + preference to “%02” on output.

      +
      • + +
    • +

      correct terminfo/termcap conversion of + “%02” and + “%03” into + “%2” and + “%3”; the result repeated the last + character.

    -

    These changes were made to help with the MinGW port:

    +

    Examples

    + +

    Along with the library and utilities, many improvements were + made to the ncurses-examples.

    + +

    These changes were made to demonstrate new extensions in + ncurses:

    • -

      added test-screens to the ncurses test-program to show - 256-characters at a time, to help with MinGW port.

      +

      add demo_new_pair program, + to demonstrate + alloc_pair, + find_pair and + free_pair functions.

      + +

      This program iterates over the possible color + combinations, allocating or initializing color pairs. For + best results, choose screen-width dividing evenly into the + number of colors. e.g.,

      + +
      + + + + + + + + + + + + + + + + + + +
      32x64,32x128  256 colors
      24x44,24x8888 colors
      32x64,24x12816 colors
      +
    • -

      modified the view test-program to load UTF-8 when built - with MinGW by using regular win32 API because the MinGW - functions mblen and mbtowc do not work.

      +

      add extended_color program, + like the older color_set + program, but using the extended color functions, with and + without the SP-functions interface.

    • -

      added “-s” option to the view - test-program to allow it to start in single-step mode, - reducing size of trace files when it is used for debugging - MinGW changes.

      +

      add picsmap program to fill + in some testing issues not met by dots, using this as the third example in a + comparison of the + ncurses versus slang libraries.

      + +

      The program can directly read X bitmap and pixmap files, + displaying a picture. It can read other image files using + ImageMagick's convert program to translate the image + into text.

      + +

      For 16-, 88- and 256-color terminal descriptions, + picsmap can load a palette + file which tells it which color palette entries to use. For + direct-colors, the terminal descriptions use the + RGB extension capability.

    -

    These changes were made to verify new extensions in ncurses:

    +

    There are other new example programs and a few scripts:

    • -

      added - form_driver_w entrypoint to wide-character forms library, - as well as form_driver_w test-program.

      +

      add dots_xcurses program to + illustrate a different approach used for extended colors + which can be contrasted with dots_curses.

    • -

      modified ncurses test-program's b/B tests to display lines - only for the attributes which a given terminal supports, to - make room for an italics test.

      +

      add list_keys program show + function keys for one or more terminal descriptions. It uses + ncurses's convention of + modifiers for special keys, based on xterm.

    • -

      modified ncurses test-program, adding - “-E” and - “-T” options to demonstrate use_env - versus use_tioctl.

      +

      add padview program, to + compare pads with direct updates in the view program.

    • -

      modified ncurses test-program's c/C tests to cycle through - subsets of the total number of colors, to better illustrate - 8/16/88/256-colors by providing directly comparable - screens.

      +

      add sp_tinfo program to + exercise the SP-functions extension of the low-level terminfo + library.

    • -

      modified the ncurses test-program to also show position - reports in 'a' test.

      +

      add test-programs for termattrs and + term_attrs functions.

      • -
    - -

    These changes were made to make the examples more useful:

    -
    • -

      added scripts for building dpkg and rpm test-packages

      +

      add test_sgr program to + exercise all combinations of the sgr capability.

    • -

      modified the hanoi test-program to show the minimum number - of moves possible for the given number of tiles.

      +

      add tput-colorcube demo + script, imitating xterm's 88- and 256-color scripts using + tput.

    • -

      modified the knight test-program to show the number of - choices possible for each position in automove option, e.g., - to allow user to follow Warnsdorff's rule to solve the - puzzle.

      +

      add tput-initc script to + demonstrate how tput may be + used to initialize a color palette from a data file.

    -

    Terminal - database

    +

    A variety of improvements were made to existing programs, both + new features as well as options added to make the set of programs + more consistent.

    -

    This release provides improvements to tic's - “-c” checking option, which was used for - example to

    +

    The ncurses program is the + largest; a proportionately large number of changes were made to + it:

    • -

      make sgr in several entries agree with other - caps.

      +

      modify a/A screens to make exiting on an escape character + depend on the start of keypad and timeout modes, to allow + better testing of function-keys.

      + +

      add “t” toggle for + notimeout function.

    • -

      correct padding in some entries where earlier versions had - miscounted the number of octal digits.

      +

      modify layout of b/B screens to allow for additional + annotation on the right margin; some terminals with partial + support did not display well.

      • -
    -

    There are several new terminal descriptions:

    - -
      -
    • - mlterm is now aliased to mlterm3
      • - -
    • - nsterm is now derived from nsterm-256color
      • - -
    • - putty-sco
      • +
    • +

      modify c/C screens to allow for extended color pairs.

      -
    • - teken is FreeBSD's "xterm" console.
      • +

      add z/Z zoom feature to make extended color pairs + easier to test.

      -
    • - terminator
      • +

      modify test-screens to take advantage of wide screens, + reducing the number of lines used for 88- and 256-colors.

      + -
    • - terminology
      • +
    • +

      +
      • -
    • - tmux is derived from screen.
      • +
    • +

      add examples to “F” screen for + WACS_D_PLUS and WACS_T_PLUS.

      +
      • -
    • several screen.XXX entries support the respective - variations for 256 colors.
      • +
    • +

      add “v” screen to show + baudrate and other values.

      +
    -

    A few entries use extensions (user-defined terminal - capabilities):

    +

    These changes were made to the other examples:

    • -

      E3, used in linux, putty and xterm-basic is - tested in the clear - program to erase a terminal's scrollback.

      +

      improve demo_menus program, + allowing mouse-click on the menu-headers to switch the active + menu. This requires a new extension option + O_MOUSE_MENU to tell the menu driver to put + mouse events which do not apply to the active menu back into + the queue so that the application can handle the event.

    • -

      XT is used in some terminfo entries to - improve usefulness for other applications than screen, which - would like to pretend that xterm's title is a - status-line.

      +

      correct logic in demo_terminfo program for + “-f” option

      improves documentation by describing new features,

      +

      improve animation in xmas + program by adding a time-delay in blinkit.

    • -

      attempts to improve the description of features which - users have found confusing

      +

      modify several test-programs which call + use_default_colors to consistently do this only + if the “-d” option is given.

    • -

      fills in overlooked descriptions of features which were - described in the NEWS file - but treated sketchily in manual pages.

      +

      modify the install-rule for ncurses-examples to put the + data files in the data directory, e.g., + /usr/share/ncurses-examples.

      • -

    Interesting - bug-fixes

    +

    Terminal + database

    + +

    There are several new terminal descriptions:

    + +
    +

    dumb-emacs-ansi, dvtm, + dvtm-256color, fbterm, + iterm2, linux-m1 minitel + entries, putty-noapp, viewdata, + and vt100+4bsd building-block.

    + +

    xterm+noalt, xterm+titlestack, + xterm+alt1049, xterm+alt+title + building blocks and xterm+direct, + xterm+indirect, xterm-direct. from + xterm + patch #331.

    + +

    several other “-direct” + descriptions to address the differences of other terminal + emulators versus xterm-direct.

    +
    + +

    There are many changes to existing terminal descriptions. Some + were updates to several descriptions:

      -
    • -

      Ada95 binding:

      +
    • use xterm+sm+1006 in several terminal + descriptions which were validated as supporting the extended + mouse feature for their respective terminal emulators.
      • + +
    • corrected sgr/sgr0 strings in a few cases + reported by tic, making those + correspond to the non-sgr settings where they differ, + but otherwise use ECMA-48 consistently.
      • + +
    • add 0.1sec mandatory delay to flash capabilities + using the VT100 reverse-video control
      • +
    +

    while others affected specific descriptions. These were + retested, to take into account new/undocumented changes by their + developers:

    + +
    +

    iterm, minitel, st, + viewdata, nsterm

    +
    + +

    while these are specific fixes based on user reports, or + warnings from tic:

    + +
    +
    + ansi building blocks
    + +
      -
    • -

      modify makefile rules to ensure that the PIC option is - not used when building a static library

      • +
    • restored rmir/smir in + ansi+idc to better match original + ansiterm+idc, add alias + ansiterm
      • +
    +
    -
  • -

    make Ada95 build-fix for big-endian architectures such - as sparc. This undoes one of the fixes from - 20110319, which added an - “Unused” member to - representation clauses, replacing that with pragmas to - suppress warnings about unused bits.

    -
    • +
    + icl6402

      -
      • +
    • used ^? for kdch1
      • +
    +
    -

    • +
    +
      +
    • made linux3.0 entry the default + linux entry
      • + +
    • modify linux2.6 entry to improve + line-drawing so that the linux3.0 entry can be + used in non-UTF-8 mode
      • + +
    • omitted selection of ISO-8859-1 for G0 in enacs + capability from linux2.6 entry, to avoid conflict with the + user-defined mapping. The reset feature uses ISO-8859-1 in + any case.
      • + +
    • modify flash capability for linux + and wyse entries to put the delay between the + reverse/normal escapes rather than after
      • + +
    • modify linux-16color to not mask dim, + standout or reverse with the ncv capability

    + pccon entries
    +
      -
    • -

      propagate error-returns from wresize, i.e., the - internal increase_size and decrease_size functions - through - resize_term.

      -
      • +
    • fixed some inconsistencies in the + pccon* entries
      • -

    • add bold to pccon+sgr+acs and + pccon-base
      • -
    • -

      modify resizeterm to always push a - KEY_RESIZE onto the fifo, even if screensize - is unchanged. Modify library to push a - KEY_RESIZE if there was a SIGWINCH, even if - it does not call resizeterm). These changes - eliminate the case where a SIGWINCH is received, but ERR - is returned from wgetch or - wgetnstr because the screen dimensions did - not change.

      -
      • +
    • add keys f12-f124 to pccon+keys

    Documentation

    + +

    As usual, this release

    + +
      +
    • +

      improves documentation by describing new features,

      +
      • + +
    • +

      attempts to improve the description of features which + users have found confusing

      +
      • + +
    • +

      fills in overlooked descriptions of features which were + described in the NEWS + file but treated sketchily in manual pages.

    -

    Configuration changes

    +

    In particular,

    -

    Major - changes

    +
      +
    • +

      Since the underlying features for + tset, + tput, and + clear have been better + integrated, the documentation now includes information on how + those tools evolved.

      -

      The ncurses 6.0 configure script - makes changes to the default value of several configure - options, depending on the --with-abi-version option - (i.e., whether its value is “5” or - “6”):

      +

      In addition to explaining the improved integration of the + tools, the manual pages made it easier to see how the tools + are similar and how they are different.

      +
      • -
      -
      --enable-const
      +
    • +

      The addch manual page has additional + information on + portability and differences from other + implementations.

      +
      • -
      -

      Feature introduced in 970405 - supports the use of const where X/Open Curses - should have, but did not. NetBSD curses does something - similar with const.

      -
      +
    • +

      The discussion of color-pairs in the attributes + manual page is improved in its + history section.

      +
      • -
      --enable-ext-colors
      +
    • +

      The documentation of the chtype, + cchar_t types and the attribute values which can + be stored in those types, in particular the + history and + portability sections of the attributes manual + page, has been improved.

      +
      • -
      -

      Extends the cchar_t structure to allow more - than 16 colors to be encoded. This applies only to the - wide-character (--enable-widec) - configuration.

      -
      +
    • +

      improve discussion of + portability in the mouse manual.

      +
      • -
      --enable-ext-mouse
      +
    • +

      The pad manual page has a section on the + origin and portability of pads.

      +
      • -
      -

      Modifies the encoding of mouse state to make room for a - 5th mouse button. That allows one to use ncurses with a wheel - mouse with xterm or similar X terminal emulators.

      -
      +
    • +

      Differences between SVr4 and X/Open Curses soft-keys are + discussed in a new section on + portability.

      +
      • -
      --enable-ext-putwin
      +
    • +

      There are updated/improved notes on portability in the + + resizeterm and + wresize manual pages.

      +
      • +
    -
    -

    Modifies the file-format written by putwin to - use printable text rather than binary files, allowing - getwin to read screen dumps written by - differently-configured ncurses libraries. The extended - getwin can still read binary screen dumps from - the same configuration of ncurses. This does not - change the ABI (the binary interface seen by calling - applications).

    -
    +

    In addition to providing background information to explain + these features and show how they evolved, there are corrections, + clarifications, etc.:

    -
    --enable-interop
    +
      +
    • +

      add note in the + addch manual about line-drawing when it depends + upon UTF-8.

      +
      • -
      -

      Modifies the FIELDTYPE structure used for the - form library to make it more generic.

      -
      +
    • +

      improve discussion of line-drawing characters in the + + add_wch manual.

      +
      • -
      --enable-lp64
      +
    • +

      explain in + clear's manual page that + it writes to the standard output.

      +
      • -
      -

      Allows an application to define _LP64 to - declare chtype and mmask_t as - simply “unsigned” rather than the - configured types using the --with-chtype and - --with-mmask_t options.

      -
      +
    • +

      improve description of + endwin.

      +
      • -
      --enable-sp-funcs
      +
    • +

      improve discussion of field validation in the + form driver manual page.

      +
      • -
      -

      Compile-in support for extended functions which accept a - SCREEN pointer, reducing the need for juggling the global SP - value with - set_term and - delscreen.

      -
      +
    • +

      clarify the use of wint_t vs + wchar_t in + get_wstr manual page.

      +
      • -
      --with-chtype=uint32_t
      +
    • +

      clarify in the + getch manual that the keypad mode affects an + application's ability to read KEY_MOUSE codes, + but does not affect KEY_RESIZE.

      -
      -

      Makes chtype explicitly a 32-bit unsigned - value.

      -
      +

      trim some obsolete/incorrect wording about + EINTR from the getch manual page

      -
      --with-mmask_t=uint32_t
      +

      improve manual pages for + getch and + get_wch to point out that they might return + user-defined values which have no predefined names in + <curses.h>

      +
      • -
      -

      Makes mmask_t explicitly a 32-bit unsigned - value.

      -
      +
    • +

      improve description of the -R option in the + + infocmp manual page

      +
      • -
      --with-tparm-arg=intptr_t
      +
    • +

      clarify in the + resizeterm manual page how + KEY_RESIZE is pushed onto the input stream.

      +
      • -
      -

      X/Open Curses declares - tparm using long for each of the parameters - aside from the formatting string, presuming that - long and char* are the same size. - This configure option uses intptr_t which - provides a better guarantee of the sizes.

      -
      - +
    • +

      document return value of + use_extended_names

      +
      • -

      The configure script no longer checks for antique compilers; - c89 is assumed as a minimum. There are a few - features from later revisions which are used when available. The - configure script makes checks to turn on useful warnings from - clang, gcc and icc. You should be able to build ncurses 6.0 with any of the current (or not so - current) C compilers available in 2015.

      - -

      The configure script, by the way, makes changes which do not - work with systems whose /bin/sh is non-POSIX. This - mainly affects Solaris (the other vendor unix systems have followed the POSIX guidelines - for the past twenty years). If you must build on Solaris, its - xpg4 - binaries suffice, e.g.,

      - -
      - - -

      - #!/bin/sh

      • -

        the configure script looks for gnatgcc if the Ada95 - binding is built, in preference to the default gcc/cc. The - script also ensures that the Ada95 binding is built with the - level of optimization as the C libraries.

        +

        improve manual page description of tset/reset + versus window-size.

      • -

        the configure script captures define's related to - -D_XOPEN_SOURCE from the configure check and adds those to - the *-config and *.pc files, to simplify use for the - wide-character libraries.

      Configuration options

      +

      There are new manual pages:

      -

      There are several new (or extended) configure options:

      +
        +
      • + user_caps documents the terminfo extensions used by + ncurses.
        • -
        -
        --disable-db-install

        +
        • +
      -
      -

      Do not install the terminal database. This is used to omit - features for packages, as done with - --without-progs. The option simplifies building - cross-compile support packages.

      -
      +

      Some of the improvements are more subtle, relating to the way + the information is presented:

      -
      --disable-gnat-projects
      +
        +
      • +

        Made minor fixes to manpage NAME/SYNOPSIS + sections to consistently use rule that either all functions + which are prototyped in SYNOPSIS are listed in the + NAME section, or the manual-page name is the sole + item listed in the NAME section. The latter is used + to reduce clutter, e.g., for the top-level library manual + pages as well as for certain feature-pages such as + SP-funcs and + threading.

        +

      -
      -

      Suppress the “w”, “t” or - “tw” suffixes which normally would be added to - the library names for the --enable-widec and - --with-pthread options.

        -

        When --with-shared is set, build libncurses++ - as a shared library. This implicitly relies upon building - with gcc/g++, since other compiler suites may have - differences in the way shared libraries are built. libtool by - the way has similar limitations.

        • +
      -
      --with-pc-suffix
      +

      Configuration changes

      -
      -

      If ".pc" files are installed, optionally add a suffix to - the files and corresponding package names to separate unusual - configurations. If no option value is given (or if it is - "none"), no suffix is added. This option is used in the test - package for ncurses6.

      -
      +

      Major + changes

      -
      --with-xterm-kbs
      +

      This release provides a new binary format for terminal + descriptions that use extended numeric capabilities. Applications + built with the wide-character ncursesw library can use + these extended numbers.

      -
      -

      Configure xterm's terminfo entries to use either BS - (^H, i.e., ASCII backspace) or DEL - (^?, or 127).

      -
      - +
        +
      • +

        This includes utilities such as tic and infocmp, because (as noted in New features), the feature + relies upon an extension to the low-level tinfo + library.

        +
        • -

        Portability

        +
      • +

        A few software packagers use a configuration option of + ncurses which allows the + low-level tinfo library to be shared between the + high-level ncurses and ncursesw libraries. + This new feature was designed to work in that configuration + as well.

        +
        • +
      + +

      Other applications (i.e., using the 8-bit ncurses + library) which read the extended terminal descriptions see those + numeric capabilities set to the maximum value for a signed 16-bit + number.

      -

      MinGW

      +

      Older versions of ncurses' + tic accept out-of-range numeric + capabilities, storing those as the maximum value for a signed + 16-bit number. Other implementations of curses (mentioned in the + discussion of + picsmap) give zero for these + out-of-range capabilities.

      -

      Most of the portability-related work since - ncurses 5.9 extended and improved the MinGW port - introduced in - ncurses 5.8.

      +

      Configuration options

      -

      The MinGW port can be readily cross-compiled:

      +

      These changes provide support for tack 1.08, released in + July 2017:

      • -

        modified configure script to allow creating dll's for - MinGW when cross-compiling.

        +

        add --without-tack configure option to refine + --with-progs configure option. Normally + tack is built outside the + ncurses tree, but a few + packagers combine it during the build. If + term_entry.h is installed, there is no advantage + to in-tree builds.

      • -

        enforced Windows-style path-separator if - cross-compiling,

        +

        adjust configure-script to define + HAVE_CURSES_DATA_BOOLNAMES symbol needed for + tack 1.08 when built in-tree. + Rather than relying upon internal "_nc_" functions, + tack now uses the boolean, + number and string capability name-arrays provided by + ncurses and SVr4 Unix curses. + It still uses term_entry.h for the definitions + of the extended capability arrays.

      • -

        added scripts for test-builds of cross-compiled packages - for ncurses6 to MinGW.

        +

        add dependency upon ncurses_cfg.h to tic's header-files; any program using + tic-library will have to + supply this file. Legacy tack + versions supply this file; ongoing tack development has dropped the + dependency upon tic-library + and new releases will not be affected.

        • +
      + +

      Other changes to the configure-script and generated files + include

      +
      • -

        added pc-files to the MinGW cross-compiling - test-packages.

        +

        add configure options to disable checks for form, menu and + panel libraries so that ncurses-examples can be built with + non-SVr4 curses implementations.

      • -

        added script for building test-packages of binaries - cross-compiled to MinGW using NSIS.

        +

        add configure option --enable-opaque-curses + for ncurses library and similar options for the + other libraries.

      • -

        added nc_mingw.h to installed headers for - MinGW port; this is needed for cross-compiling ncurses-examples.

        +

        add configure option --disable-wattr-macros + for use in cases where one wants to use the same headers for + ncurses5/ncurses6 development, by suppressing the + wattr* macros which differ due to the introduction + of extended colors

      • -

        added test-packages for cross-compiling ncurses-examples - using the MinGW test-packages.

        +

        modify configure macro for shared-library rules to use + -Wl,-rpath rather than -rpath to + work around a bug in scons

        • -
      -

      The MinGW-specific Windows driver accounts for several - changes:

      - -
      • -

        wide-character display is made usable by replacing MinGW's - non-working wcrtomb and wctomb - functions.

        +

        improve ncurses-examples' configure script to define as + needed NCURSES_WIDECHAR for platforms where + _XOPEN_SOURCE_EXTENDED does not work. Also + modified the test program to ensure that if building with + ncurses, that the + cchar_t type is checked, since that is normally + (since 20111030) + ifdef'd depending on this test.

      • -

        implemented some display features: beep, - flash, - - curs_set.

        +

        modify configure script to handle the case where + tic-library is renamed, but + the --with-debug option is used by itself + without normal or shared libraries

      • -

        the driver handles repainting on endwin/refresh - combination.

        +

        modify editing script which generates resulting.map to + work with the clang configuration on recent FreeBSD, which + gives an error on an empty "local" section.

      • -

        modified treatment of TERM variable for MinGW - port to allow explicit use of the Windows console driver by - checking if $TERM is set to - “#win32console” or an abbreviation - of that.

        +

        improve configure check for setting the + WILDCARD_SYMS variable; on ppc64 the variable is + in the Data section rather than + Text.

      • -

        the Windows driver also matches the special - TERM value “unknown”

        +

        correct result of configure option + --without-fallbacks, which caused FALLBACK_LIST + to be set to "no"

      • -

        the driver now returns characters for special keys, (like - ansi.sys does), when keypad mode is off, rather - than returning nothing at all.

        +

        modify --with-pkg-config-libdir option to + make it possible to install “.pc” files even if + pkg-config is not found. Limit + this change, to suppress the actual install if it is not + overridden to a valid directory at install time.

      • -

        the driver checks a new environment variable - NCURSES_CONSOLE2 to optionally work around a deficiency - in Console2 (and its descendent - ConsoleZ) which hang when an application creates - a console buffer.

        +

        disallow “no” as a possible value for + --with-shlib-version option, overlooked in + cleanup-changes for 20000708.

      -

      Finally, there are other improvements:

      +

      Portability

      + +

      Many of the portability changes are implemented via the + configure script:

      • -

        MinGW is one of the configurations where ncurses installs by default into /usr

        +

        improve configure script's CF_CC_ENV_FLAGS + macro to allow for compiler wrappers such as ccache. This change moves only the + preprocessor, optimization and warning flags to + CPPFLAGS and CFLAGS, leaving the + residue in CC. That happens to work for + gcc's various + “model” options, but may require tuning for other + compilers.

        • -
      • configuration for cross-compiling uses AC_CHECK_TOOLS in - preference to AC_PATH_PROGS when searching for ncurses*-config, - e.g., in Ada95/configure and test/configure.
        • -
      • -

        extend Windows support to work with MSYS2;

        - -
          -
        • -

          this works with a scenario where there is an - ANSI-escape handler such as ansicon running - in the console window.

          -
          • - -
        • wrap isatty calls with a macro, provide a - corresponding set of support routines to address - differences between MinGW and MSYS2.
          • -
        +

        modify ncurses-examples' configure script to use + pkg-config for the extra + form/menu/panel libraries, to be more consistent with the + handling of the curses/ncurses library.

      • -

        ensure WINVER is defined in makefiles rather - than using headers.

        +

        add configuration checks to build with NetBSD + curses, which for example lacks + use_env.

      • -

        add check for the gnatprep - “-T” option.

        +

        change ncurses-examples to use attr_t vs + chtype to follow X/Open documentation more + closely since Solaris xpg4-curses uses different values for + WA_xxx vs A_xxx + that rely on attr_t being an unsigned short. Tru64 aka OSF1, + HPUX, AIX did as ncurses does, + equating the two sets.

      • -

        work around a bug introduced by - gcc 4.8.1 in MinGW which breaks "trace" feature.

        +

        modify several test programs to reflect that ncurses honors existing signal handlers in + initscr, while other implementations do not.

      • -

        add a driver-name method to each of the drivers.

        +

        add configure check for openpty to + ncurses-examples' configure script, for ditto.

        • -
      - -

      Other - ports

      -

      These changes affect certain platforms (ports):

      +
    • +

      improve check for working poll function by + using posix_openpt as a fallback in case there + is no valid terminal on the standard input

      +
      • -
      • -

        the configure script knows how to build shared libraries - with DragonFlyBSD and Interix.

        +

        modify ncurses-examples' configure script to check for + pthread dependency of + ncursest or ncursestw library when building + the ncurses examples, e.g., in + case weak symbols are used.

      • -

        support for AIX shared libraries is improved, tested with - AIX 5.3, 6.1 and 7.1 with both gcc 4.2.4 and cc:

        +

        add checks in ncurses-examples' configure script for some + functions neither in 4.3BSD curses, nor based on X/Open + Curses:

        • -

          the shared-library suffix for AIX 5 and 6 is now - ".so"

          +

          modify a loop limit in firework.c to work around + absense of limit checks in some libraries.

        • -

          the -brtl option is used with AIX 5-7; it - is needed to link with the shared libraries.

          +

          fill the last row of a window with + “?” in firstlast if waddch does + not return ERR on the lower-right + corner.

      • -

        the configure --enable-pc-files option takes - into account the PKG_CONFIG_PATH - variable.

        -
        • +

        build-fixes for the Portland Group (PGI) compilers

        -
      • -

        the configure option --with-pkg-config-libdir - provides control over the actual directory into which - pc-files are installed.

        -
        • +
          +
        • +

          accept whitespace in sed expression for generating + expanded.c

          +
          • -
        • -

          the build scripts add explicit -ltinfo, etc., to the - generated ".pc" file when ld option - “--as-needed” is used, or when - ncurses and tinfo are installed without using rpath.

          +
        • +

          modify configure check that g++ compiler warnings are + not used.

          +
          • + +
        • +

          add configure check for -fPIC option needed for shared + libraries.

          +
          • +
      • -

        the configure script disallows conflicting options - “--with-termlib” and - “--enable-term-driver”.

        +

        modify configure script for clang as used on FreeBSD, to + work around clang's differences in exit codes vs gcc.

      • -

        the check for missing c++ compiler to work when no error - is reported, and no variables set is improved (see note for - 20021206).

        +

        fixes for configure/build using clang on OSX

        + +
          +
        • +

          do not redefine “inline” in + ncurses_cfg.h; this was originally to solve + a problem with gcc/g++, but is aggravated by clang's + misuse of symbols to pretend it is gcc.

          +
          • + +
        • +

          add braces to configure script to prevent unwanted + addition of “-lstdc++” option to + the CXXLIBS symbol.

          +
          • + +
        • +

          improve/update test-program used for checking + existence of stdc++ library.

          +
          • + +
        • +

          if $CXXLIBS is set, the linkage test uses + that in addition to $LIBS.

          +
          • +
      • -

        the misc/gen_edit.sh script selects a "linux" entry which - works with the current kernel rather than assuming it is - always "linux3.0"

        +

        fixes for OS/2:

        + +
          +
        • +

          use button instead of kbuf[0] in + EMX-specific part of lib_mouse.c

          +
          • + +
        • +

          support building with libtool on OS/2

          +
          • + +
        • +

          use stdc++ library with OS/2 kLIBC

          +
          • + +
        • +

          clear configure script's cf_XOPEN_SOURCE + for OS/2, to work with its header files

          +
          • +
      • -

        the test/configure script makes it simpler to override - names of curses-related libraries, to help with linking with - pdcurses in MinGW environment.

        +

        add “newer” baudrate symbols to the + baudrate function in the ncurses library as + well as to a corresponding table in tset.

      • -

        the configure-script/ifdef's allow the BSD OLD_TTY feature - to be suppressed if the type of ospeed is - configured using the option --with-ospeed to not - be a short. By default, it is a - short for termcap-compatibility.

        +

        modify ncurses-examples savescreen to work with AIX and HPUX.

      • -

        the MKlib_gen.sh script works around a recent change in - gcc 5 (released mid-2015) which essentially - emits multiple #line statements for the same - position in a file.

        +

        define WIN32_LEAN_AND_MEAN for MinGW port, + making builds faster.

      • -

        the configure script works with Minix3.2 (see note - on portability)

        +

        add a configure check for wcwidth versus the + ncurses line-drawing + characters, to use in special-casing systems such as Solaris. + Solaris, however, requires a special case that maps Unicode + line-drawing characters into the acsc string for non-Unicode + locales. Solaris also has a misconfigured wcwidth which marks + all of the line drawing characters as double-width.

      • -

        OS/2 redux:

        +

        string-hacks (non-standard):

        • -

          the configure script supports OS/2 kLIBC.

          +

          fix configure script to record when + strlcat is found on OpenBSD.

          +
          • + +
        • +

          add --enable-string-hacks option to + ncurses-examples' configure script.

        • -

          the --with-lib-prefix option allows - configuring for old/new flavors of OS/2 EMX.

          +

          completed string-hacks for sprintf, etc., + including the ncurses-examples programs.

          +
          • + +
        • +

          make --enable-string-hacks option work + with Debian by checking for the "bsd" library and its + associated "<bsd/string.h>" header.

      • -

        improved configure-script checks for - _XOPEN_SOURCE:

        +

        workaround for Debian's antique/unmaintained version of + mawk:

+# The keytab feature was introduced in 0.9.12 (February 2000) with "linux" and
+# "vt100" key-table files along with a compiled-in default key-table.
+#
+# The main difference between the two keytabs was that the developer equated
+# "vt100" with xterm, and noticed that the Linux console's F1-F5 differed from
+# that.  For the same reason, the home/end keys differ.  A VT100 had none of
+# that.  The otherwise identical keytabs have definitions to model the VT52
+# cursor-keys and the VT100 cursor-keys with application versus normal modes.
+#
+# An "x11r5" keytab (displayed in the menu as "X11 R5") was added in January
+# 2001, and shortly after retitled to "XFree 3.x.x".  Both it and "vt100" were
+# dropped from the install in June 2008.
+#
+# The default keytab added in January 2000 was originally titled "X11 R6",
+# and likewise retitled to "XFree 4".
+#
+# A "solaris" keytab was added in Febrary 2005, copying the "vt100" keytab
+# and changing backspace to ^H, removing that keytab's attempt to model the
+# VT100 keypad and VT52 (KDE #20459).
+#
+# The developers made changes to the default and linux keytabs.  Comparing
+# the original and 2018 versions using diffstat:
+#	default: 119 added, 147 deleted, 28 unchanged
+#	linux:   47 added, 28 deleted, 104 unchanged
+#
+# Most of the change for the default keytab was to make konsole act more like
+# xterm.  That was a feature named AnyMod which came in May 2005 for KDE #92749
+# (see also Redhat #122815).  Later, in June 2007 the compiled-in keytab was
+# made an external file (like "linux" and "solaris"), and some further
+# refinement made.  But there are still flaws in the scheme.
+#
+# Essentially AnyMod maps the xterm "PC-style" modifier codes such as 2 for
+# Shift into a placeholder in the table entries.  That works well if all of the
+# modified keys are modified in the same way.  But xterm does not do that.  The
+# first 4 function keys are used in xterm to support the VT100 PF1-PF4 keypad
+# keys.  For example, F2 sends \EOQ in both terminals because of this feature.
+# But a shifted F2 (F14=F2+12) differs like this, in infocmp's listing:
+#	kf14: '\E[1;2Q', '\EO2Q'.
+#
+# In effect, a quarter of konsole's function-keys are different from xterm.
+#
+# It is not a simple blunder:
+# a) xterm patch #121 (November 1999), providing the first version of the
+#    PC-style modifiers would send \EO2Q
+# b) xterm patch #216 (July 2006) amended this and other details, provided
+#    better documentation for the modifiers and made the behavior configurable,
+#    e.g., using the modifyFunctionKeys resource.  The reason why it sends
+#    \E[1;2Q is that \E[O2Q is not a legal ECMA-48 control sequence.  The
+#    changelog points this out as "avoid sending SS3 with parameters".
+# c) That came after AnyMod was introduced, but still early enough that one
+#    might expect konsole's developers to followup.  Twelve years later that
+#    has yet to happen.
+#
+# As of 2018, konsole still provides 3 keyboard profiles ("XFree 4", "linux",
+# "solaris").
