These notes are for ncurses + @VERSION@, released February 12, 2020.
+ +This release is designed to be source-compatible with + ncurses 5.0 through 6.1; providing + extensions to the application binary interface (ABI). Although + the source can still be configured to support the ncurses 5 ABI, the reason for the release is + to reflect improvements to the ncurses 6 ABI and the supporting utility + programs.
+ +There are, of course, numerous other improvements, listed in + this announcement.
+ +The most important + bug-fixes/improvements dealt with user-defined capabilities + in terminal descriptions. The release notes also mention some + other bug-fixes, but are focused on new features and improvements + to existing features since ncurses + 6.1 release.
+ +There are several new features:
+ +O_EDGE_INSERT_STAY + tells the form library to optionally delay cursor movement on + a field edge/boundary
+O_INPUT_FIELD + extension to form library allows a dynamic field to shrink if + the new limit is smaller than the current field size.
+added exit_curses and + exit_terminfo to + replace internal symbols for leak-checking.
+added curses_trace, + to replace trace().
+Additionally, to improve performance other changes (and + extensions) are provided in this release:
+ +mouse decoding now handles shift/control/alt logic when + decoding xterm's 1006 mode
+ncurses now defines a limit for wgetnstr, wgetn_wstr when + length is negative or “too large”.
+there is now no buffer-size limit when reading the + $TERMCAP + variable.
+the $TERMCAP + variable may be interpreted as a fallback to a terminfo + entry
++ mvcur now decides whether to use hard-tabs, using + xt, tbc + and hts as clues.
+extended colors are improved by modifying an internal call + to + vid_puts to pass extended color pairs e.g., from + tty_update.c and lib_mvcur.c
+the initialization functions now avoid + relying upon persistent data for the result from getenv
+scrolling is improved:
+ +improved loop limits in _nc_scroll_window + handle a case where the scrolled data is a pad which is + taller than the window.
+These are revised features:
+ +used “const” in some prototypes + rather than NCURSES_CONST where X/Open Curses was + updated to do this, e.g., wscanw, newterm, + the terminfo interface. Also use “const” + for consistency in the termcap interface, which was withdrawn + by X/Open Curses in Issue 5 (2007). As of Issue 7, X/Open + Curses still lacks “const” for certain + return values, e.g., keyname.
+modified wbkgd + and wbkgrnd + to improve compatibility with SVr4 curses, changing the way + the window rendition is updated when the background character + is modified
+improved terminfo write/read by modifying the fourth item + of the extended header to denote the number of valid strings + in the extended string table (see term(5)).
+modified the initialization checks for mouse so that the + xterm+sm+1006 + block will work with terminal descriptions not mentioning + xterm.
+These were done to limit or ultimately deprecate features:
+ +deprecated safe-sprintf, since the + vsnprintf function, which does what was needed, was + standardized long ago.
+marked vwprintw + and vwscanw as deprecated; recommend using vw_printw + and vw_scanw, respectively.
+added deprecation warnings for internal functions called + by older versions of tack.
+removed unused _nc_import_termtype2 function.
+These are improvements to existing features:
+ +check parameter of set_escdelay, + return ERR if negative.
+check parameter of set_tabsize, return + ERR if not greater than zero
+correct a status-check in _nc_read_tic_entry() so that if + reading a hex/b64 $TERMINFO, + and the $TERM + does not match, fall-through to the compiled-in search + list.
+amend check for + repeat_char to handle a case where setlocale() was + called after initscr
+move macro for is_linetouched + inside NCURSES_NOMACROS + ifndef.
+use _nc_copy_termtype2 rather than direct + assignment in setupterm, + in case it is called repeatedly using fallback terminfo + descriptions
+improve workaround for Solaris wcwidth versus line-drawing + characters
+add checks in repair_subwindows + to keep the current position and scroll-margins inside the + resized subwindow.
+correct a buffer-limit in write_entry.c for + systems that use caseless filenames.
+improved build-time utility report_offsets:
+ +add categories, e.g., "w" for wide-character, "t" for + threads to make the report more readable. Reorganized the + structures reported to make the categories more + apparent.
+add NCURSES_GLOBALS and + NCURSES_PRESCREEN to report to show how similar + the different libtinfo configurations are.
+modified some header files to ensure that those include + necessary files except for the previously-documented + cases
+added some traces in initialization to show whether a + fallback entry is used.
+made minor optimization to reduce calls to + _nc_reserve_pairs
+These are corrections to existing features:
+ +fix a special case in PutAttrChar where a cell is + marked as alternate-character set, but the terminal does not + actually support the given graphic character. This would + happen in an older terminal such as vt52, which + lacks most line-drawing capability.
+corrected flag for "seq" method of db 1.8.5 interface, + needed by toe on some of the BSDs.
+modify comparison in make_hash.c to correct a special case + in collision handling for Caps-hpux11
+add extended_slk_color{,_sp} symbols to the appropriate + package/*.{map,sym} files
+modify lib_setup to avoid calling pthread_self() without + first verifying that the address is valid, i.e., for weak + symbols
+add a couple of broken-linker symbols to the list of + versioned symbols to help with link-time optimization versus + weak symbols.
+Several improvements were made to the utility programs:
+ +Several changes were made to the generated ncurses*config + scripts and the analogous “.pc” files to + reduce differences between the configurations they report:
+ +modified the ncurse*-config and pc-files to more closely + match for the -I and -l options.
+filtered out linker-specs from the --libs + report.
+amended the ncurses*-config and pc-files to take into + account the rpath hack which differed between those + files.
+modified generated ncurses*config and ncurses.pc, + ncursesw.pc, etc., to list helper libraries such as gpm for + static linking.
+Along with the library and utilities, improvements were made + to the ncurses-examples. Most of + this activity aimed at improving the test-packages. A few changes + are more generally useful, e.g., for the main ncurses + test-program, and for analyzing traces using the + tracemunch script:
+ +improve recovery from error when reading command-character + in test/ncurses.c, showing the relevant error + message and not exiting on EINTR.
+improve tracemunch, by keeping track of + TERMINAL* values, and if tracing was first turned on + after initialization, attempt to show distinct screen, window + and terminal names anyway.
+modify tracemunch to accept filename parameters + in addition to use as a pipe/filter.
+update tracemunch to work with perl + 5.26.2, which changed the rules for escaping regular + expressions.
+add some checks in tracemunch for undefined + variables.
+modify TurnOn/TurnOff macros (in + lib_vidattr.c and lib_vid_attr.c) to avoid expansion of + “CUR” in trace.
+There are other new demo/test programs and reusable + examples:
+ +A variety of improvements were made to existing programs, both + new features as well as options added to make the set of programs + more consistent.
+ +add “-l” option to test/background, + to dump screen contents in a form that lets different curses + implementations be compared.
+add “@” command to test/ncurses + F-test, to allow rapid jump to different character pages.
+added enum, regex examples to test/demo_forms
+amend Scaled256() macro in test/picsmap.c to cover the + full range 0..1000
+corrected pathname used in Ada95 sample programs for + explain.txt, to work with test-packages, and used an + awk script to split the resulting pathname when it would be + too long for a single line.
+ignore interrupted system-call in test/ncurses's + command-line, e.g., if the terminal were resized.
+improved ifdef's for TABSIZE variable, to help + with AIX/HPUX ports.
+There are several new terminal descriptions:
+ +++ +alacritty, domterm, kitty, + mintty, mintty-direct, ms-terminal, + n7900, nsterm-build309, + nsterm-direct, screen5, ti703, + ti707, ti703-w, ti707-w + vscode, vscode-direct, xterm-mono, + xterm.js
+
There are many changes to existing terminal descriptions. Some + were updates to several descriptions:
+ +while others affected specific descriptions. These were + retested, to take into account changes by their developers:
+ +++ +terminator, st
+
while these are specific fixes based on reviewing + documentation, user reports, or warnings from tic:
+ +A few entries use extensions (user-defined terminal + capabilities):
+ +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 to providing background information to explain + these features and show how they evolved, there are corrections, + clarifications, etc.:
+ +Corrections:
+ +Clarify in manual pages that vwprintw
+ and vwscanw
+ are obsolete.
+ They have not been part of X/Open Curses since 2007.
New/improved history and portability sections:
+ +Improvements for user_caps.5:
+ +Other improvements:
+ +There are no new manual pages (all of the manual page updates + are to existing pages).
+ +Some of the improvements are more subtle, relating to the way + the information is presented. For instance, the generated + terminfo.5 file uses a different table layout, allowing it to use + space on wide terminals more effectively.
+ +While there were many bugs fixed during development of ncurses + 6.2, only a few (the reason for this release) were both important + and interesting. Most of the bug-fixes were for local issues + which did not affect compatibility across releases. Since those + are detailed in the NEWS file no elaboration is needed here.
+ +The interesting bugs were in tic/infocmp's handling of + user-defined capabilities. These were not recent bugs. Initially + it was a simple problem:
+ +One of simpleterm's contributors copied some definitions + for using tmux's user-defined capabilities in + + late in 2016.
+ ++++diff --git a/st.info b/st.info +@@ -185,7 +185,10 @@ st| simpleterm, + tsl=\E]0;, + xenl, + vpa=\E[%i%p1%dd, +- ++# Tmux unofficial extensions, see TERMINFO EXTENSIONS in tmux(1) ++ Se, ++ Ss, ++ Tc, + + st-256color| simpleterm with 256 colors, + use=st, ++
Later, in (referring to a version from + mid-2017), a user asked to have it updated in + ncurses.
+However, it had an error from the change in late 2016. The + terminal description made what tmux expected to be + string actually a + boolean.
+ +Over the years, there were problems with each of + simpleterm's terminal descriptions. I repaired those, and + usually dealt with the problem.
+The difference in this case was that when compiling the + terminal database, tic may have in memory the + definitions for more than one terminal description (so that + it can resolve “use=” clauses). Seeing + two different types for the same name, in certain situations + it would incorrectly merge the symbol tables for the two + terminal descriptions.
+On simpleterm's side, their bug was finally fixed in + + late 2019, three years after the bug was created.
+For ncurses, the elapsed time to fix this bug was less than + three years. Someone reported a problem with the terminal + description a few weeks after releasing ncurses 6.1 (in tmux #1264), and + the terminal description was updated that week (ncurses patch + 20180224):
+ +++ ++20180224 + + modify _nc_resolve_uses2() to detect incompatible types when merging + a "use=" clause of extended capabilities. The problem was seen in a + defective terminfo integrated from simpleterm sources in 20171111, + compounded by repair in 20180121. + + correct Ss/Ms interchange in st-0.7 entry (tmux #1264) -TD ++
The larger part of that change added a check to prevent a + simple merge of terminal descriptions where the same user-defined + name was used with different types. But it raised some + questions:
+ +Was there a reliable way to manage terminal descriptions + which used the same extended name in different ways?
+Should ncurses provide a registry of well-known extended + names, with their types?
+Since the correction to terminfo.src + could have been readily adopted by packagers, there was nothing + more to be done from ncurses' standpoint on that part. But + improving ncurses to prevent issues like that is the reason for + making a release.
+ +Nothing more (constructive) was mentioned with regard to + simpleterm. But a few problems were found in the handling of + user-defined capabilities:
+ +Forward-references to user-defined capabilities in a + “use=” clause did not allocate new data + for each use. In tic, successive compilation of + terminal entries could add user-defined capabilities to the + wrong terminal entry.
+ +This was not noticed before, since xterm's terminal + descriptions were the main users of the feature, and almost + all of the uses of the building-blocks which contained + user-defined capabilities were backward-references.
+There is one (documented) case where ncurses 6.1 supports + a user-defined capability that could be any type (i.e., + “RGB”). The check added in February 2018 to guard + against mismatches did not handle all of the combinations + needed.
+Both of these issues dated from the original implementation of + user-defined capabilities. Fixing them does not change the + terminal database, but a older tic without the fixes + will not be able to handle terminfo sources which rely upon those + fixes. Starting in June 2019, the download link for the terminfo + source file was capped at that date. The development sources have + an up-to-date copy of the file, for people with a legitimate need + for it.
+ +The “-c” (check) option of tic + is not very useful if it cannot offer advice on parameters needed + for user-defined capabilities. The various Caps files + were reorganized to reduce redundancy, and in the common portion + (Caps-ncurses), + a registry of user-defined capabilities is provided for use by + tic. While users can still define their own custom + capabilities, tic will not offer any advice when their + parameters do not match.
+ +In ncurses 6.2, tic makes a special check to allow + any type for RGB, but its being able to do this relies + upon fixes made in the ncurses library in mid-2019.
+ +There are no major changes. Several new options were added to + ease integration of packages with systems using different + versions of GNAT and ncurses. Also, + improvements were made to configure checks.
+ +There are a few new/modified configure options:
+ +helps work around a filename conflict with Debian packages + versus test-packages.
+allows one to rename the “AdaCurses” library + (at least one packager prefers a lowercase name).
+now ensures there is a value, and adds the fallback + information to top-level Makefile summary.
+check for pcre-posix library to help with MinGW port.
+help work around problems building fallback source using + pre-6.0 tic/infocmp.
+option value can now be a relative pathname.
+Many of the portability changes are implemented via the + configure script:
+ +ignore $TERMINFO + as a default value in configure script if it came from the + infocmp -Q option.
+distinguish gcc from icc and clang when the + --enable-warnings option is not used, to avoid + unnecessary warnings about unrecognized inline options
+consistently prepend new libraries as they are found + during configuration, rather than relying upon the linker to + resolve order dependencies of libraries.
+modified configure scripts to reduce relinking/ranlib + during library install :
+ +add configure check for getenv to work around + implementation shown in Emscripten which overwrites the + previous return value on each call.
+ +Use that to optionally suppress START_TRACE + macro, whose call to getenv may not work + properly
+change target configure level for _XOPEN_SOURCE + to 600 to address use of vsscanf and + setenv.
+reduce use of _GNU_SOURCE for current glibc where + _DEFAULT_SOURCE combines with + _XOPEN_SOURCE
+ +Allow for Cygwin's newlib when checking for the + _DEFAULT_SOURCE symbol.
+ +MidnightBSD is now checked for the + _XOPEN_SOURCE-related definitions.
+If the check for va_copy or __va_copy + fails,
+ +several changes to support a port to Ultrix 3.1:
+ +The test/configure script (used for ncurses-examples) + is improved:
+ +Here are some of the other portability fixes:
+ +added dummy "check" rule in top-level and test-Makefile to + simplify building test-packages for ArchLinux.
+dropped library-dependency on psapi for MinGW port, since + win_driver.c defines PSAPI_VERSION to 2, making it + use GetProcessImageFileName from kernel32.dll
+made build-fixes for configuration using --program-suffix + with Ada95, noticed with MacOS but applicable to other + platforms without libpanelw, etc.
+modified ncurses/Makefile.in to fix a case where + Debian/testing changes to the ld --as-needed configuration + broke ncurses-examples test packages.
+used _WIN32/_WIN64 in preference to + __MINGW32__/__MINGW64__ symbols to simplify + building with Microsoft Visual C++, since the former are + defined in both compiler configurations.
+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).

Zeyd Ben-Halim started ncurses + from a previous package pcurses, written by Pavel Curtis. Eric S. + Raymond continued development. Jürgen Pfeifer wrote most of + the form and menu libraries.
+ +Ongoing development work is done by Thomas E. Dickey. Thomas + E. Dickey has acted as the maintainer for the Free Software + Foundation, which holds a copyright on ncurses for + releases 4.2 through 6.1. Following the release of ncurses 6.1, + effective as of release 6.2, copyright for ncurses reverted to + Thomas E. Dickey (see the ncurses FAQ for + additional information).

The release notes make scattered references to these pages, + which may be interesting by themselves:
+ +The distribution provides a newer version of the + terminfo-format terminal description file once maintained by + Eric + Raymond . Unlike the older version, the termcap and + terminfo data are provided in the same file, which also provides + several user-definable extensions beyond the X/Open + specification.
+ +You can find lots of information on terminal-related topics + not covered in the terminfo file at + Richard Shuford's archive . The collection of computer + manuals at bitsavers.org has also been + useful.
