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 + 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.

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). + + 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. + + 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. + + 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. + + Terminal database + + 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. + + 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 + + A few entries use extensions (user-defined terminal capabilities): + * E3, used in linux, putty and xterm-basic is tested in the + [53]clear program to erase a terminal's scrollback. + * TS is used in the [54]xterm+sl building block to help deprecate + the misuse of tsl for xterm's title-string. + * 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. + * xm is used in examples [55]xterm-1005 and [56]xterm-1006 to + illustrate a way to make mouse handling more general + + A few terminals support italics and/or dim capabilities.

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. + * Low-level interfaces + + 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. + + change "%l" behavior in tparm to push the string length onto + the stack rather than saving the formatted length into the + output buffer. + + modify name-comparison for tgetstr, etc., to accommodate + legacy applications as well as to improve compatbility with + BSD 4.2 termcap implementations (see note for [66]980725). + * High-level interfaces + + 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 [67]960418). + + add a check in internal function waddch_nosync to ensure that + tab characters are treated as control characters; some broken + locales claim they are printable. + + modify menu library to ensure that a menu's top-row is + adjusted as needed to ensure that the current item is on the + screen + + fix special case where double-width character overwrites a + single- width character in the first column. + + 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.

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. + + 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). + + 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. + _________________________________________________________________ + +Features of ncurses + + The ncurses package is fully upward-compatible with SVr4 (System V + Release 4) curses: + * All of the SVr4 calls have been implemented (and are documented). + * ncurses supports all of the for SVr4 curses features including + keyboard mapping, color, forms-drawing with ACS characters, and + automatic recognition of keypad and function keys. + * ncurses provides these SVr4 add-on libraries (not part of X/Open + Curses): + + the panels library, supporting a stack of windows with + backing store. + + the menus library, supporting a uniform but flexible + interface for menu programming. + + the form library, supporting data collection through + on-screen forms. + * ncurses's terminal database is fully compatible with that used by + SVr4 curses. + + ncurses supports user-defined capabilities which it can see, + but which are hidden from SVr4 curses applications using the + same terminal database. + + It can be optionally configured to match the format used in + related systems such as AIX and Tru64. + + Alternatively, ncurses can be configured to use hashed + databases rather than the directory of files used by SVr4 + curses. + * The ncurses utilities have options to allow you to filter terminfo + entries for use with less capable curses/terminfo versions such as + the HP/UX and AIX ports.

Overview

+ +

The ncurses (new curses) library + is a free software emulation of curses in System V Release 4.0 + (SVr4), and more. It uses terminfo format, supports pads and + color and multiple highlights and forms characters and + function-key mapping, and has all the other SVr4-curses + enhancements over BSD curses. SVr4 curses is better known today + as X/Open Curses.

In mid-June 1995, the maintainer of 4.4BSD curses declared that he considered 4.4BSD curses obsolete, and encouraged the - keepers of Unix releases such as BSD/OS, FreeBSD and NetBSD to - switch over to ncurses.

+ keepers of unix releases such as + BSD/OS, FreeBSD and NetBSD to switch over to ncurses.

+ +

Since 1995, ncurses has been + ported to many systems:

+ +
    +
  • It is used in almost every system based on the Linux kernel + (aside from some embedded applications).
    • + +
  • It is used as the system curses library on OpenBSD, FreeBSD + and OSX.
    • + +
  • It is used in environments such as Cygwin and MinGW. The + first of these was EMX on OS/2 Warp.
    • + +
  • It is used (though usually not as the system + curses) on all of the vendor unix + systems, e.g., AIX, HP-UX, IRIX64, SCO, Solaris, Tru64.
    • + +
  • It should work readily on any ANSI/POSIX-conforming + unix.
    • +
+ +

The distribution includes the library and support utilities, + including

+ +
    +
  • captoinfo, + a termcap conversion tool
    • + +
  • clear, + utility for clearing the screen
    • + +
  • infocmp, + the terminfo decompiler
    • + +
  • tabs, + set tabs on a terminal
    • + +
  • tic, + the terminfo compiler
    • + +
  • toe, + list (table of) terminfo entries
    • + +
  • tput, + utility for retrieving terminal capabilities in shell + scripts
    • + +
  • tset, + to initialize the terminal
    • +
+ +

Full manual pages are provided for the library and tools.

+ +

The ncurses distribution is + available via anonymous FTP at the GNU distribution site

Release + Notes

+ +

These notes are for ncurses + @VERSION@, released August 8, 2015.

+ +

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 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 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.

    +
    • + +
  • +

    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.

    +
    • +
+ +

Library + improvements

+ +

Output + buffering

+ +

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

+ +
    +
  • + initscr (the simplest) accepts no parameters.
    • + +
  • + newterm accepts parameters for the stream input and + output
    • + +
  • + 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 + 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: + 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 “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:

+ +
+
+
“.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 tack to omit + many of the ncurses private symbols + (beginning with “_nc_”). Here are + counts of globals versus locals:

+ +
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
ConfigSymbolsGlobalsLocals"_nc_"
ncurses976796180332
ncursesw1089905184343
ncursest979804175358
ncursestw1098914184372
+
+ +

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)

+
+
+ +

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 + use_tioctl function
    • + +
  • +

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

    +
    • + +
  • +

    added + A_ITALIC extension.

    +
    • + +
  • +

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

    +
    • + +
  • +

    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:

    + +
    + 
    +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 + 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).

    +
    • +
+ +

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:

+ +
    +
  • +

    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):

    + +
    + 
    +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 + + 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.

    +
    • +
+ +

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.

    +
    • +
+ +

Examples

+ +

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).

+ +

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 + + 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 + mvderwin and test for recursive + 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 + 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.

    +
    • +
+ +

Terminal + database

+ +

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.

    +
    • +
+ +

There are several new terminal descriptions:

+ + + +

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

+ +
    +
  • +

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

    +
    • + +
  • +

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

    +
    • + +
  • +

    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.

    +
    • + +
  • +

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

    +
    • +
+ +

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.

+ +
    +
  • konsole, mlterm3 (italics)
    • + +
  • nsterm (dim)
    • + +
  • screen (dim)
    • + +
  • vte (dim, italics)
    • + +
  • xterm (dim, italics)
    • +
+ +

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.

    +
    • +
+ +

In addition, the mechanism for producing HTML versions of the + documentation has been improved:

+ + + +

Interesting + bug-fixes

+ +
    +
  • +

    Ada95 binding:

    + +
      +
    • +

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

      +
      • + +
    • +

      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.

      +
      • +
    +
    • + +
  • +

    Color and attributes:

    + +
      +
    • +

      parenthesize parameter of COLOR_PAIR and + PAIR_NUMBER in curses.h in case it happens + to be a comma-expression.

      +
      • + +
    • +

      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.

      +
      • + +
    • +

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

      +
      • + +
    • +

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

      +
      • +
    +
    • + +
  • +

    Resizing the screen:

    + +
      +
    • +

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

      +
      • + +
    • +

      add check for zero/negative dimensions for + resizeterm and resize_term.

      +
      • + +
    • +

      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.

      +
      • +
    +
    • + +
  • +

    Low-level interfaces

    + +
      +
    • +

      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.

      +
      • + +
    • +

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

      +
      • + +
    • +

      modify name-comparison for tgetstr, etc., to + accommodate legacy applications as well as to improve + compatbility with BSD 4.2 termcap implementations (see + note for 980725).

      +
      • +
    +
    • + +
  • High-level interfaces + +
      +
    • +

      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).

      +
      • + +
    • +

      add a check in internal function + waddch_nosync to ensure that tab characters + are treated as control characters; some broken locales + claim they are printable.

      +
      • + +
    • +

      modify menu library to ensure that a menu's top-row is + adjusted as needed to ensure that the current item is on + the screen

      +
      • + +
    • +

      fix special case where double-width character + overwrites a single- width character in the first + column.

      +
      • +
    +
    • +
+ +

Configuration changes

+ +

Major + changes

-

The ncurses code was developed under GNU/Linux. It has been in - use for some time with OpenBSD as the system curses library, and - on FreeBSD and NetBSD as an external package. It should port - easily to any ANSI/POSIX-conforming UNIX. It has even been ported - to OS/2 Warp!

+

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”):

-

The distribution includes the library and support utilities, - including a terminfo compiler tic(1), a decompiler infocmp(1), - clear(1), tput(1), tset(1), and a termcap conversion tool - captoinfo(1). Full manual pages are provided for the library and - tools.

+
+
--enable-const
+ +
+

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.

+
+ +
--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 + set_term and + delscreen.

+
-

The ncurses distribution is available via anonymous FTP at the - GNU distribution site ftp://ftp.gnu.org/gnu/ncurses/ .
+

--with-chtype=uint32_t
- It is also available at ftp://invisible-island.net/ncurses/ .

+
+

Makes chtype explicitly a 32-bit unsigned + value.

+
+ +
--with-mmask_t=uint32_t
-

Release Notes

+
+

Makes mmask_t explicitly a 32-bit unsigned + value.

+
-

This release is designed to be upward compatible from ncurses - 5.0 through 5.8; very few applications will require - recompilation, depending on the platform. These are the - highlights from the change-log since ncurses 5.8 release.

+
--with-tparm-arg=intptr_t
-

This is a bug-fix release, correcting a small number of urgent - problems in the ncurses library from the 5.8 release.

+
+

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.

+
+
-

It also improves the Ada95 binding:

+

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
+ WHAT=`hostname|sed -e 's/\..*//'`
+ + OUT=configure.out
+ cat >>$OUT <<EOF/
+ ** `date`
+ ** node: $WHAT
+ ** user: `id`
+ ** conf: $*
+ EOF/
+  
+ SHELL=/bin/sh
+ if test -f /usr/xpg4/bin/sh
+ + then
+         CONFIG_SHELL=/usr/xpg4/bin/sh
+         export CONFIG_SHELL
+ +         SHELL=$CONFIG_SHELL
+ fi
+  
+ rm -f config.status config.cache
+ TOP=$HOME/$WHAT
+ $SHELL ./configure --verbose \
+ +         --disable-echo \
+ +         --disable-overwrite \
+ +         --enable-warnings \
+ +         --with-warnings \
+ +         --prefix=$TOP $* 2>&1 | tee -a $OUT
+ +

+
+ +

Other major changes to the configure script include:

    -
  • fixes a longstanding portability problem with its use of - the set_field_type - function. Because that function uses variable-length argument - lists, its interface with gnat does not work with certain - platforms.
    • +
  • +

    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

    -
  • improves configurability and portability, particularly when - built separately from the main ncurses tree. The 5.8 release - introduced scripts which can be used to construct separate - tarballs for the Ada95 and ncurses examples. +
    +

    adacurses-config to + adacurses5-config and
    + adacursesw-config to + adacursesw5-config

    +
    +
    • -

    Those were a proof of concept. For the 5.9 release, those - scripts are augmented with rpm- and dpkg-scripts used in test - builds against a variety of gnat- and system ncurses versions - as old as gnat 3.15 and ncurses 5.4 (see snapshots and - systems tested here.

    +
  • +

    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.

    • -
  • additional improvements were made for portability of the - ncurses examples, adding rpm- and dpkg-scripts for test-builds. - See this - page for snapshots and other information.
    • +
  • +

    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.

    +

Features of Ncurses

+

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
-

The ncurses package is fully compatible with SVr4 (System V - Release 4) curses:

+
+

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).

+
+
+ +

Portability

+ +

MinGW

+ +

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

+ +

The MinGW port can be readily cross-compiled:

    -
  • All 257 of the SVr4 calls have been implemented (and are - documented).
    • +
  • +

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

    +
    • -
  • Full support for SVr4 curses features including keyboard - mapping, color, forms-drawing with ACS characters, and - automatic recognition of keypad and function keys.
    • +
  • +

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

    +
    • -
  • An emulation of the SVr4 panels library, supporting a stack - of windows with backing store, is included.
    • +
  • +

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

    +
    • -
  • An emulation of the SVr4 menus library, supporting a - uniform but flexible interface for menu programming, is - included.
    • +
  • +

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

    +
    • -
  • An emulation of the SVr4 form library, supporting data - collection through on-screen forms, is included.
    • +
  • +

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

    +
    • -
  • Binary terminfo entries generated by the ncurses tic(1) - implementation are bit-for-bit-compatible with the entry format - SVr4 curses uses.
    • +
  • +

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

    +
    • -
  • The utilities have options to allow you to filter terminfo - entries for use with less capable - curses/terminfo versions such - as the HP/UX and AIX ports.
    • +
  • +

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

    +
-

The ncurses package also has many useful extensions over - SVr4:

+

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

    -
  • The API is 8-bit clean and base-level conformant with the - X/OPEN curses specification, XSI curses (that is, it implements - all BASE level features, and most EXTENDED features). It - includes many function calls not supported under SVr4 curses - (but portability of all calls is documented so you can use the - SVr4 subset only).
    • +
  • +

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

    +
    • + +
  • +

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

    +
    • -
  • Unlike SVr3 curses, ncurses can write to the - rightmost-bottommost corner of the screen if your terminal has - an insert-character capability.
    • +
  • +

    the driver handles repainting on endwin/refresh + combination.

    +
    • -
  • Ada95 and C++ bindings.
    • +
  • +

    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.

    +
    • -
  • Support for mouse event reporting with X Window xterm and - FreeBSD and OS/2 console windows.
    • +
  • +

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

    +
    • -
  • Extended mouse support via Alessandro Rubini's gpm - package.
    • +
  • +

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

    +
    • -
  • The function wresize allows you to resize - windows, preserving their data.
    • +
  • +

    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.

    +
    • +
-
  • The function use_default_colors allows you to - use the terminal's default colors for the default color pair, - achieving the effect of transparent colors.
    • +

    Finally, there are other improvements:

    -
  • The functions keyok and - define_key allow you to better control the use of - function keys, e.g., disabling the ncurses KEY_MOUSE, or by - defining more than one control sequence to map to a given key - code.
    • +
      +
    • +

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

      +
      • -
    • Support for 256-color terminals, such as modern xterm, when - configured using the --enable-ext-colors - option.
      • +
    • 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.
      • -
    • Support for 16-color terminals, such as aixterm - and modern xterm.
      • +
    • +

      extend Windows support to work with MSYS2;

      -
    • Better cursor-movement optimization. The package now - features a cursor-local-movement computation more efficient - than either BSD's or System V's.
      • +
        +
      • +

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

        +
        • -
      • Super hardware scrolling support. The screen-update code - incorporates a novel, simple, and cheap algorithm that enables - it to make optimal use of hardware scrolling, line-insertion, - and line-deletion for screen-line movements. This algorithm is - more powerful than the 4.4BSD curses quickch - routine.
        • +
      • wrap isatty calls with a macro, provide a + corresponding set of support routines to address + differences between MinGW and MSYS2.
        • +
      + -
    • Real support for terminals with the magic-cookie glitch. - The screen-update code will refrain from drawing a highlight if - the magic- cookie unattributed spaces required just before the - beginning and after the end would step on a non-space - character. It will automatically shift highlight boundaries - when doing so would make it possible to draw the highlight - without changing the visual appearance of the screen.
      • +
    • +

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

      +
      • -
    • It is possible to generate the library with a list of - pre-loaded fallback entries linked to it so that it can serve - those terminal types even when no terminfo tree or termcap file - is accessible (this may be useful for support of - screen-oriented programs that must run in single-user - mode).
      • +
    • +

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

      +
      • -
    • The tic(1)/captoinfo utility provided with ncurses has the - ability to translate many termcaps from the XENIX, IBM and - AT&T extension sets.
      • +
    • +

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

      +
      • -
    • A BSD-like tset(1) utility is provided.
      • +
    • +

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

      +
      • +
    -
  • The ncurses library and utilities will automatically read - terminfo entries from $HOME/.terminfo if it exists, and compile - to that directory if it exists and the user has no write access - to the system directory. This feature makes it easier for users - to have personal terminfo entries without giving up access to - the system terminfo directory.
    • - -
  • You may specify a path of directories to search for - compiled descriptions with the environment variable - TERMINFO_DIRS (this generalizes the feature provided by - TERMINFO under stock System V.)
    • +

    Other + ports

    -
  • In terminfo source files, use capabilities may refer not - just to other entries in the same source file (as in System V) - but also to compiled entries in either the system terminfo - directory or the user's $HOME/.terminfo directory.
    • - -
  • A script (capconvert) is provided to help - BSD users transition from termcap to terminfo. It gathers the - information in a TERMCAP environment variable and/or a - ~/.termcap local entries file and converts it to an equivalent - local terminfo tree under $HOME/.terminfo.
    • - -
  • Automatic fallback to the /etc/termcap file can be compiled - in when it is not possible to build a terminfo tree. This - feature is neither fast nor cheap, you don't want to use it - unless you have to, but it's there.
    • - -
  • The table-of-entries utility toe makes it - easy for users to see exactly what terminal types are available - on the system.
    • - -
  • The library meets the XSI requirement that every macro - entry point have a corresponding function which may be linked - (and will be prototype-checked) if the macro definition is - disabled with #undef.
    • - -
  • An HTML "Introduction to Programming with NCURSES" document - provides a narrative introduction to the curses programming - interface.

    State of the Package

    - -

    Numerous bugs present in earlier versions have been fixed; the - library is far more reliable than it used to be. Bounds checking - in many `dangerous' entry points has been improved. The code is - now type-safe according to gcc -Wall. The library has been - checked for malloc leaks and arena corruption by the Purify - memory-allocation tester.

    - -

    The ncurses code has been tested with a wide variety of - applications including (versions starting with those noted):

    +

    These changes affect certain platforms (ports):

      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 definition works starting with Solaris 10.

        +
        • + +

    +

    The ncurses package is fully + upward-compatible with SVr4 (System V Release 4) curses:

    -
    pinfo
    +
      +
    • +

      All of the SVr4 calls have been implemented (and are + documented).

      +
      • -
      Lynx-like info browser. https://alioth.debian.org/projects/pinfo/
      +

      ncurses provides these SVr4 + add-on libraries (not part of X/Open Curses):

      + +
        +
      • +

        the panels library, supporting a stack of windows with + backing store.

        +
        • + +
      • +

        the menus library, supporting a uniform but flexible + interface for menu programming.

    +
  • +

    ncurses's terminal database is + fully compatible with that used by SVr4 curses.

    + +
      +
    • ncurses supports + user-defined capabilities which it can see, but which are + hidden from SVr4 curses applications using the + same terminal database.
      • + +
    • +

      It can be optionally configured to match the format + used in related systems such as AIX and Tru64.

      +
      • + +
    • +

      Alternatively, ncurses can + be configured to use hashed databases rather than the + directory of files used by SVr4 curses.

      +
      • +
    +
    • -

    as well as some that use ncurses for the terminfo support - alone:

    +
  • +

    The ncurses utilities have + options to allow you to filter terminfo entries for use with + less capable curses/terminfo versions such + as the HP/UX and AIX ports.

    +
    • + -
    -
    minicom
    +

    The ncurses package also has many + useful extensions over SVr4:

      +
      • + +
    • +

      Ada95 and C++ bindings.

      +
      • + +
    • +

      Support for mouse event reporting with X Window xterm and + FreeBSD and OS/2 console windows.

      +
      • + +
    • +

      Extended mouse support via Alessandro Rubini's gpm + package.

      +
      • + +
    • +

      The function wresize allows you to resize + windows, preserving their data.

      +
      • + +
    • +

      The function use_default_colors allows you to + use the terminal's default colors for the default color pair, + achieving the effect of transparent colors.

      +
      • + +
    • +

      The functions keyok and + define_key allow you to better control the use + of function keys, e.g., disabling the ncurses KEY_MOUSE, or by defining more than + one control sequence to map to a given key code.

      +
      • + +
    • +

      Support for 256-color terminals, such as modern xterm.

      +
      • + +
    • +

      Support for 16-color terminals, such as aixterm + and modern xterm.

      +
      • + +
    • +

      The tic/captoinfo + utility provided with ncurses has + the ability to translate many termcaps from the XENIX, IBM + and AT&T extension sets.

      +
      • + +
    • +

    • It is used in almost every system based on the Linux kernel + (aside from some embedded applications).
      • + +
    • It is used as the system curses library on OpenBSD, FreeBSD + and OSX.

    Release Notes

    This release is designed to be upward - compatible from ncurses 5.0 through 5.8; very few applications - will require recompilation, depending on the platform. These are - the highlights from the change-log since ncurses 5.8 release. -

    - This is a bug-fix release, correcting a small number of urgent problems - in the ncurses library from the 5.8 release. -

    - It also improves the Ada95 binding: -

      -
    • fixes a longstanding portability problem with its use of the - set_field_type - function. Because that function uses variable-length argument lists, - its interface with gnat does not work with certain platforms. -
    • improves configurability and portability, particularly when built - separately from the main ncurses tree. The 5.8 release introduced - scripts which can be used to construct separate tarballs for the - Ada95 and ncurses examples. -

      Those were a proof of concept. For the 5.9 release, those - scripts are augmented with rpm- and dpkg-scripts used in test builds - against a variety of gnat- and system ncurses versions as old as - gnat 3.15 and ncurses 5.4 (see snapshots and systems tested - here. -

    • additional improvements were made for portability of the - ncurses examples, adding rpm- and dpkg-scripts for test-builds. - See - this page - for snapshots and other information. -

    Features of Ncurses

    The ncurses package is fully - compatible with SVr4 (System V Release 4) curses: - -
      -
    • All 257 of the SVr4 calls have been implemented (and are - documented).
      • - -
    • Full support for SVr4 curses features including keyboard - mapping, color, forms-drawing with ACS characters, and - automatic recognition of keypad and function keys.
      • - -
    • An emulation of the SVr4 panels library, supporting a stack - of windows with backing store, is included.
      • - -
    • An emulation of the SVr4 menus library, supporting a - uniform but flexible interface for menu programming, is - included.
      • - -
    • An emulation of the SVr4 form library, supporting data - collection through on-screen forms, is included.
      • - -
    • Binary terminfo entries generated by the ncurses tic(1) - implementation are bit-for-bit-compatible with the entry format - SVr4 curses uses.
      • - -
    • The utilities have options to allow you to filter terminfo - entries for use with less capable - curses/terminfo versions such - as the HP/UX and AIX ports.
      • -
    The ncurses package also has many useful extensions over - SVr4: - -
      -
    • The API is 8-bit clean and base-level conformant with the - X/OPEN curses specification, XSI curses (that is, it implements - all BASE level features, and most EXTENDED features). It - includes many function calls not supported under SVr4 curses - (but portability of all calls is documented so you can use the - SVr4 subset only).
      • - -
    • Unlike SVr3 curses, ncurses can write to the - rightmost-bottommost corner of the screen if your terminal has - an insert-character capability.
      • - -
    • Ada95 and C++ bindings.
      • - -
    • Support for mouse event reporting with X Window xterm and - FreeBSD and OS/2 console windows.
      • - -
    • Extended mouse support via Alessandro Rubini's gpm - package.
      • - -
    • The function wresize allows you to resize - windows, preserving their data.
      • - -
    • The function use_default_colors allows you to - use the terminal's default colors for the default color pair, - achieving the effect of transparent colors.
      • - -
    • The functions keyok and - define_key allow you to better control the use of - function keys, e.g., disabling the ncurses KEY_MOUSE, or by - defining more than one control sequence to map to a given key - code.
      • - -
    • Support for 256-color terminals, such as modern xterm, when - configured using the --enable-ext-colors - option.
      • - -
    • Support for 16-color terminals, such as aixterm - and modern xterm.
      • - -
    • Better cursor-movement optimization. The package now - features a cursor-local-movement computation more efficient - than either BSD's or System V's.
      • - -
    • Super hardware scrolling support. The screen-update code - incorporates a novel, simple, and cheap algorithm that enables - it to make optimal use of hardware scrolling, line-insertion, - and line-deletion for screen-line movements. This algorithm is - more powerful than the 4.4BSD curses quickch - routine.
      • - -
    • Real support for terminals with the magic-cookie glitch. - The screen-update code will refrain from drawing a highlight if - the magic- cookie unattributed spaces required just before the - beginning and after the end would step on a non-space - character. It will automatically shift highlight boundaries - when doing so would make it possible to draw the highlight - without changing the visual appearance of the screen.
      • - -
    • It is possible to generate the library with a list of - pre-loaded fallback entries linked to it so that it can serve - those terminal types even when no terminfo tree or termcap file - is accessible (this may be useful for support of - screen-oriented programs that must run in single-user - mode).

      Release + Notes

      + +

      These notes are for ncurses + 6.0, released August 8, 2015.

      + +

      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 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 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.

        +
        • + +
      • +

        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.

        +
        • +
      + +

      Library + improvements

      + +

      Output + buffering

      + +

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

      + +
        +
      • + initscr (the simplest) accepts no parameters.
        • + +
      • + newterm accepts parameters for the stream input and + output
        • + +
      • + 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 + 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: + 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 “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:

      + +
      +
      +
      “.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 tack to omit + many of the ncurses private symbols + (beginning with “_nc_”). Here are + counts of globals versus locals:

    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

      +

    Miscellaneous

    -
  • The tic(1)/captoinfo utility provided with ncurses has the - ability to translate many termcaps from the XENIX, IBM and - AT&T extension sets.
    • - -
  • A BSD-like tset(1) utility is provided.
    • - -
  • The ncurses library and utilities will automatically read - terminfo entries from $HOME/.terminfo if it exists, and compile - to that directory if it exists and the user has no write access - to the system directory. This feature makes it easier for users - to have personal terminfo entries without giving up access to - the system terminfo directory.
    • - -
  • You may specify a path of directories to search for - compiled descriptions with the environment variable - TERMINFO_DIRS (this generalizes the feature provided by - TERMINFO under stock System V.)
    • - -
  • In terminfo source files, use capabilities may refer not - just to other entries in the same source file (as in System V) - but also to compiled entries in either the system terminfo - directory or the user's $HOME/.terminfo directory.
    • - -
  • A script (capconvert) is provided to help - BSD users transition from termcap to terminfo. It gathers the - information in a TERMCAP environment variable and/or a - ~/.termcap local entries file and converts it to an equivalent - local terminfo tree under $HOME/.terminfo.
    • - -
  • Automatic fallback to the /etc/termcap file can be compiled - in when it is not possible to build a terminfo tree. This - feature is neither fast nor cheap, you don't want to use it - unless you have to, but it's there.
    • - -
  • The table-of-entries utility toe makes it - easy for users to see exactly what terminal types are available - on the system.
    • - -
  • The library meets the XSI requirement that every macro - entry point have a corresponding function which may be linked - (and will be prototype-checked) if the macro definition is - disabled with #undef.
    • - -
  • An HTML "Introduction to Programming with NCURSES" document - provides a narrative introduction to the curses programming - interface.
    • - - -

    State of the Package

    Numerous bugs present in earlier - versions have been fixed; the library is far more reliable than - it used to be. Bounds checking in many `dangerous' entry points - has been improved. The code is now type-safe according to gcc - -Wall. The library has been checked for malloc leaks and arena - corruption by the Purify memory-allocation tester. - -

    The ncurses code has been tested with a wide variety of - applications including (versions starting with those noted):

    +

    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 + use_tioctl function
      • + +
    • +

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

      +
      • + +
    • +

      added + A_ITALIC extension.

      +
      • + +
    • +

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

      +
      • + +
    • +

      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:

      + +
      + 
      +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 + 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).

      +
      • +
    + +

    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:

    + +
      +
    • +

      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):

      + +
      + 
      +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 + + 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.

      +
      • +
    + +

    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.

      +
      • +
    + +

    Examples

    + +

    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).

    + +

    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 + + 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 + mvderwin and test for recursive + 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 + 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.

      +
      • +
    + +

    Terminal + database

    + +

    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.

      +
      • +
    + +

    There are several new terminal descriptions:

    + + + +

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

    + +
      +
    • +

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

      +
      • + +
    • +

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

      +
      • + +
    • +

      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.

      +
      • + +
    • +

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

      +
      • +
    + +

    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.

    + +
      +
    • konsole, mlterm3 (italics)
      • + +
    • nsterm (dim)
      • + +
    • screen (dim)
      • + +
    • vte (dim, italics)
      • + +
    • xterm (dim, italics)
      • +
    + +

    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.

      +
      • +
    + +

    In addition, the mechanism for producing HTML versions of the + documentation has been improved:

    + + + +

    Interesting + bug-fixes

    + +
      +
    • +

      Ada95 binding:

      + +
        +
      • +

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

        +
        • + +
      • +

        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.

        +
        • +
      +
      • + +
    • +

      Color and attributes:

      + +
        +
      • +

        parenthesize parameter of COLOR_PAIR and + PAIR_NUMBER in curses.h in case it happens + to be a comma-expression.

        +
        • + +
      • +

        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.

        +
        • + +
      • +

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

        +
        • + +
      • +

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

        +
        • +
      +
      • + +
    • +

      Resizing the screen:

      + +
        +
      • +

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

        +
        • + +
      • +

        add check for zero/negative dimensions for + resizeterm and resize_term.

        +
        • + +
      • +

        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.

        +
        • +
      +
      • + +
    • +

      Low-level interfaces

      + +
        +
      • +

        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.

        +
        • + +
      • +

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

        +
        • + +
      • +

        modify name-comparison for tgetstr, etc., to + accommodate legacy applications as well as to improve + compatbility with BSD 4.2 termcap implementations (see + note for 980725).

        +
        • +
      +
      • + +
    • High-level interfaces + +
        +
      • +

        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).

        +
        • + +
      • +

        add a check in internal function + waddch_nosync to ensure that tab characters + are treated as control characters; some broken locales + claim they are printable.

        +
        • + +
      • +

        modify menu library to ensure that a menu's top-row is + adjusted as needed to ensure that the current item is on + the screen

        +
        • + +
      • +

        fix special case where double-width character + overwrites a single- width character in the first + column.

        +
        • +
      +
      • +
    + +

    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”):

    -
    cdk
    +
    --enable-const
    + +
    +

    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.

    +
    -
    Curses Development Kit
    - http://invisible-island.net/cdk/
    +
    --enable-ext-colors
    - http://www.vexus.ca/products/CDK/ +
    +

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

    +
    -
    ded
    +
    --enable-ext-mouse
    -
    directory-editor
    - http://invisible-island.net/ded/
    +
    +

    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.

    +
    -
    dialog
    +
    --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).

    +
    -
    the underlying application used in Slackware's setup, and - the basis for similar applications on GNU/Linux.
    - http://invisible-island.net/dialog/
    +
    --enable-interop
    -
    lynx
    +
    +

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

    +
    -
    the character-screen WWW browser
    - http://lynx.isc.org/release/
    +
    --enable-lp64
    -
    Midnight Commander
    +
    +

    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.

    +
    -
    file manager
    - http://www.midnight-commander.org/
    +
    --enable-sp-funcs
    -
    mutt
    +
    +

    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.

    +
    -
    mail utility
    - http://www.mutt.org/
    +
    --with-chtype=uint32_t
    + +
    +

    Makes chtype explicitly a 32-bit unsigned + value.

    +
    -
    ncftp
    +
    --with-mmask_t=uint32_t
    -
    file-transfer utility
    - http://www.ncftp.com/
    +
    +

    Makes mmask_t explicitly a 32-bit unsigned + value.

    +
    -
    nvi
    +
    --with-tparm-arg=intptr_t
    -
    New vi versions 1.50 are able to use ncurses versions 1.9.7 - and later.
    - https://sites.google.com/a/bostic.com/keithbostic/nvi
    +
    +

    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.

    +
    -
    pinfo
    +

    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
    + WHAT=`hostname|sed -e 's/\..*//'`
    + + OUT=configure.out
    + cat >>$OUT <<EOF/
    + **     `date`
    + ** node:     $WHAT
    + ** user:     `id`
    + ** conf: $*
    + EOF/
    +  
    + SHELL=/bin/sh
    + if test -f /usr/xpg4/bin/sh
    + + then
    +         CONFIG_SHELL=/usr/xpg4/bin/sh
    +         export CONFIG_SHELL
    + +         SHELL=$CONFIG_SHELL
    + fi
    +  
    + rm -f config.status config.cache
    + TOP=$HOME/$WHAT
    + $SHELL ./configure --verbose \
    + +         --disable-echo \
    + +         --disable-overwrite \
    + +         --enable-warnings \
    + +         --with-warnings \
    + +         --prefix=$TOP $* 2>&1 | tee -a $OUT
    + +

    +
    + +

    Other major changes to the configure script include:

    -
    Lynx-like info browser. https://alioth.debian.org/projects/pinfo/
    +
      +
    • +

      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.

      +
      • +

    +

    Configuration options

    -
    newsreader, supporting color, MIME http://www.tin.org/
    - as well as some that use ncurses for the terminfo support - alone: +

    There are several new (or extended) configure options:

    -
    minicom
    +
    --disable-db-install
    -
    terminal emulator
    - http://alioth.debian.org/projects/minicom/
    +
    +

    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.

    +
    -
    vile
    +
    --disable-gnat-projects
    -
    vi-like-emacs
    - http://invisible-island.net/vile/
    +
    +

    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).

    +
    -

    The ncurses distribution includes a selection of test programs - (including a few games).

    +

    Portability

    + +

    MinGW

    + +

    Most of the portability-related work since + ncurses 5.9 extended and improved the MinGW port + introduced in + 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 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: beep, + flash, + + 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 + 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 + 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 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 + 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 mid-2015) which essentially + emits multiple #line statements for the same + position in a file.

      +
      • + +
    • +

      the configure script works with Minix3.2 (see 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.

        +
        • +
      +
      • +
    +
    + +

    Features of ncurses

    + +

    The ncurses package is fully + upward-compatible with SVr4 (System V Release 4) curses:

    + +
      +
    • +

      All of the SVr4 calls have been implemented (and are + documented).

      +
      • + +
    • +

      ncurses supports all of the + for SVr4 curses features including keyboard mapping, color, + forms-drawing with ACS characters, and automatic recognition + of keypad and function keys.

      +
      • + +
    • +

      ncurses provides these SVr4 + add-on libraries (not part of X/Open Curses):

      + +
        +
      • +

        the panels library, supporting a stack of windows with + backing store.

        +
        • + +
      • +

        the menus library, supporting a uniform but flexible + interface for menu programming.

        +
        • + +
      • +

        the form library, supporting data collection through + on-screen forms.

        +
        • +
      +
      • + +
    • +

      ncurses's terminal database is + fully compatible with that used by SVr4 curses.

      + +
        +
      • ncurses supports + user-defined capabilities which it can see, but which are + hidden from SVr4 curses applications using the + same terminal database.
        • + +
      • +

        It can be optionally configured to match the format + used in related systems such as AIX and Tru64.

        +
        • + +
      • +

        Alternatively, ncurses can + be configured to use hashed databases rather than the + directory of files used by SVr4 curses.

        +
        • +
      +
      • + +
    • +

      The ncurses utilities have + options to allow you to filter terminfo entries for use with + less capable curses/terminfo versions such + as the HP/UX and AIX ports.

      +
      • +
    + +

    The ncurses package also has many + useful extensions over SVr4:

    + +
      +
    • +

      The API is 8-bit clean and base-level conformant with the + X/OPEN curses specification, XSI curses (that is, it + implements all BASE level features, and most EXTENDED + features). It includes many function calls not supported + under SVr4 curses (but portability of all calls is documented + so you can use the SVr4 subset only).

      +
      • + +
    • +

      Unlike SVr3 curses, ncurses + can write to the rightmost-bottommost corner of the screen if + your terminal has an insert-character capability.

      +
      • + +
    • +

      Ada95 and C++ bindings.

      +
      • + +
    • +

      Support for mouse event reporting with X Window xterm and + FreeBSD and OS/2 console windows.

      +
      • + +
    • +

      Extended mouse support via Alessandro Rubini's gpm + package.

      +
      • + +
    • +

      The function wresize allows you to resize + windows, preserving their data.

      +
      • + +
    • +

      The function use_default_colors allows you to + use the terminal's default colors for the default color pair, + achieving the effect of transparent colors.

      +
      • + +
    • +

      The functions keyok and + define_key allow you to better control the use + of function keys, e.g., disabling the ncurses KEY_MOUSE, or by defining more than + one control sequence to map to a given key code.

      +
      • + +
    • +

      Support for 256-color terminals, such as modern xterm.

      +
      • + +
    • +

      Support for 16-color terminals, such as aixterm + and modern xterm.

      +
      • + +
    • +

      Better cursor-movement optimization. The package now + features a cursor-local-movement computation more efficient + than either BSD's or System V's.

      +
      • + +
    • +

      Super hardware scrolling support. The screen-update code + incorporates a novel, simple, and cheap algorithm that + enables it to make optimal use of hardware scrolling, + line-insertion, and line-deletion for screen-line movements. + This algorithm is more powerful than the 4.4BSD curses + quickch routine.

      +
      • + +
    • +

      Real support for terminals with the magic-cookie glitch. + The screen-update code will refrain from drawing a highlight + if the magic- cookie unattributed spaces required just before + the beginning and after the end would step on a non-space + character. It will automatically shift highlight boundaries + when doing so would make it possible to draw the highlight + without changing the visual appearance of the screen.

      +
      • + +
    • +

      It is possible to generate the library with a list of + pre-loaded fallback entries linked to it so that it can serve + those terminal types even when no terminfo tree or termcap + file is accessible (this may be useful for support of + screen-oriented programs that must run in single-user + mode).

      +
      • + +
    • +

      The tic/captoinfo + utility provided with ncurses has + the ability to translate many termcaps from the XENIX, IBM + and AT&T extension sets.

      +
      • + +
    • +

      A BSD-like tset + utility is provided.

      +
      • + +
    • +

      The ncurses library and + utilities will automatically read terminfo entries from + $HOME/.terminfo if it exists, and compile to that directory + if it exists and the user has no write access to the system + directory. This feature makes it easier for users to have + personal terminfo entries without giving up access to the + system terminfo directory.

      +
      • + +
    • +

      You may specify a path of directories to search for + compiled descriptions with the environment variable + TERMINFO_DIRS (this generalizes the feature provided by + TERMINFO under stock System V.)

      +
      • + +
    • +

      In terminfo source files, use capabilities may refer not + just to other entries in the same source file (as in System + V) but also to compiled entries in either the system terminfo + directory or the user's $HOME/.terminfo directory.

      +
      • + +
    • +

      The table-of-entries utility toe + makes it easy for users to see exactly what terminal types + are available on the system.

      +
      • + +
    • +

      The library meets the XSI requirement that every macro + entry point have a corresponding function which may be linked + (and will be prototype-checked) if the macro definition is + disabled with #undef.

      +
      • + +
    • +

      Extensive documentation is provided (see the + Additional Reading section of the + ncurses FAQ for online documentation).

      +
      • +

    form_driver_w

+       type must be passed as well,  to  enable  the  library  to

 .SH DESCRIPTION
+.SS form_driver
 Once a form has been posted (displayed), you should funnel input events to it
 through \fBform_driver\fR.  This routine has three major input cases:
 .bP
 The input is a form navigation request.
 Navigation request codes are constants defined in \fB\fP,
-which are distinct from the key- and character codes returned by \fBwgetch\fP.
+which are distinct from the key- and character codes returned by \fBwgetch\fP(3X).
 .bP
 The input is a printable character.
 Printable characters (which must be positive, less than 256) are
 checked according to the program's locale settings.
 .bP
 The input is the KEY_MOUSE special key associated with an mouse event.
+.SS form_driver_w
+.PP
+This extension simplifies the use of the forms library using wide characters.
+The input is either a key code (a request) or a wide character
+returned by \fBget_wch\fP(3X).
+The type must be passed as well,
+to enable the library to determine whether the parameter
+is a wide character or a request.
+.SS Form-driver requests
