Overview
Release Notes
- These notes are for ncurses 6.4, released December 31, 2022.
+ These notes are for ncurses 6.5, released April 27, 2024.
This release is designed to be source-compatible with ncurses 5.0
- through 6.3; providing extensions to the application binary interface
+ through 6.4; 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.
The most important bug-fixes/improvements dealt with robustness
issues. The release notes also mention some other bug-fixes, but are
focused on new features and improvements to existing features since
- ncurses 6.3 release.
+ ncurses 6.4 release.
Library improvements
New features
- There are no new features in this release.
+ These are new features:
+ * The low-level terminfo and termcap interfaces are used both by the
+ higher-level curses library, as well as by many applications.
+ The functions which convert parameterized terminal capability
+ strings for output to the terminal (tiparm and tparm) analyze the
+ capability string to determine which parameters are strings (i.e.,
+ addresses), versus numbers (not addresses).
+ The library's analysis of a capability string may differ from the
+ calling application's design if environment variables are used to
+ point to an invalid terminal database. This is a longstanding
+ problem with all implementations of terminfo, dating from the
+ early 1980s.
+ Two new functions address this problem: by providing a function
+ which allows the calling application to tell ncurses how many
+ string-parameters to expect:
+ + tiscan_s helps applications check formatting capabilities
+ that would be passed to tiparm_s.
+ + tiparm_s provides applications a way to tell ncurses what the
+ expected parameters are for a capability.
+ * The ncurses library supports a compile-time feature (enabled with
+ the configure --enable-check-size option) which simplifies
+ initialization with terminals which do not negotiate window
+ (screen) size. This is done in setupterm, by providing for using
+ ANSI cursor-position report (in user6/user7 terminfo capabilities)
+ to obtain the screen size if neither environment variables or
+ ioctl is used.
+ The ncurses test-program with options "-E -T" demonstrates this
+ feature.
+ * add functions to query tty-flags in SCREEN
+
+ This release drops compatibility with obsolete versions of tack, e.g.,
+ pre-1.08
Other improvements
These are improvements to existing features:
- * modify delscreen to more effectively delete all windows on the
- given screen.
- * modify wnoutrefresh to call pnoutrefresh if its parameter is a
- pad, rather than treating it as an error, and modify new_panel to
- permit its window-parameter to be a pad
- * modify curses_trace() to show the trace-mask as symbols, e.g.,
- TRACE_ORDINARY, DEBUG_LEVEL(3).
- * improve checks for valid mouse events when an intermediate mouse
- state is not part of the mousemask specified by the caller
- * allow extended-color number in opts parameter of wattr_on.
- * improve _tracecchar_t2 formatting of base+combining character.
- * trim out some unwanted linker options from ncurses*config and .pc
- files seen in Fedora 36+.
- * improve shell-scripts with shellcheck
- * improve use of "trap" in shell scripts, using a script.
- * modify make-tar.sh scripts to make timestamps more predictable.
+ * In addition to the new, safer function tiparm_s, ncurses adds
+ checks to make the older tiparm, tparm and tgoto functions safer:
+ + the terminfo functions tiparm and tparm ensure that the
+ capability string comes from the terminal description which
+ ncurses loads, rather than from random data which the
+ application happens to have.
+ + the tgoto function disallows capabilities which its analysis
+ shows will attempt to use string parameters.
+ + ncurses uses internal functions which correspond to tiparm,
+ and tgoto which ensure that the capability strings which are
+ passed to these functions come from the loaded terminal
+ description.
+ * improve check in lib_tparm.c, ensuring that a char* fits into a
+ TPARM_ARG
+ * modify _nc_syserr_abort to use _nc_env_access, rather than only
+ checking root uid
+ * improve thread lock in lib_trace.c
+ * modify flushinp to use file descriptors in SCREEN, rather than
+ from TERMINAL, and check if they are for a terminal, like SVr4
+ * modify mcprint to use file descriptor in SCREEN, for consistency
+ * modify internal function _nc_read_file_entry to show relevant
+ filename in warnings
+ * improve checks in internal function convert_string for corrupt
+ terminfo entry
+ * review/improve handling of out-of-memory conditions
+ * limit delays to 30 seconds, i.e., padding delays in terminfo, as
+ well as napms and delay_output functions
+ * fix reallocation loop for vsnprintf in _nc_sprintf_string by
+ copying the va_list variable
+ * modify delscreen to limit the windows which it creates to just
+ those associated with the screen
+ * modify endwin to return an error if it is called again without an
+ intervening screen update
+ * modify wenclose to handle pads
+ * eliminate use of PATH_MAX in lib_trace.c
+ * provide for any CCHARW_MAX greater than 1
These are corrections to existing features:
- * modify misc/gen-pkgconfig.in to allow for the case where the
- library directory does not yet exist, since this is processed
- before doing an install
- * set trailing null on string passed from winsnstr to wins_nwstr.
- * modify waddch_literal to allow for double-width base character
- when merging a combining character
+ * correct loop termination condition in waddnstr and waddnwstr
+ * improve parsing in internal function _nc_msec_cost, allowing a
+ single decimal point
+ * amend parameter check for entire string versus specific length in
+ winsnstr and wins_nwstr to match Solaris; make similar correction
+ to wins_nwstr
+ * correct internal function wadd_wch_literal when adding a
+ non-spacing character to a double-width character
+ * correct definition of Charable macro for non-wide ncurses library
+ .

- no gprbuild package is available.
- * install Ada95 sample programs in libexecdir, adding a wrapper
- script to invoke those.

Interesting bug-fixes
- While there were many bugs fixed during development of ncurses 6.4,
- 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 those dealing with memory leaks and buffer
- overflows. Although the utilities are designed for text files (which
- they do properly), some choose to test them with non-text files.
- * Text files contain no embedded nulls. Also, they end with a
- newline. Feeding tic non-text files exposed a few cases where the
- program did not check for those issues. As a result, further
- processing of the input found limit-checks whose assumptions were
- invalid.
- * Fixing the limit-checks (first) found a problem with tic managing
- the list of strings in a terminal description. In merging two
- terminal descriptions (i.e., the "use=" feature), tic was not
- allocating a complete copy. A quick repair for that introduced a
- memory leak.
- * The checks for non-text files are improved (i.e., embedded nulls
- in the input file will cause tic to reject it rather than
- attempting to process it).
- * The string allocations in tic are likewise improved.
+ The changes to tparm, tgoto which improve the design of the low-level
+ interfaces are interesting, but are not bug-fixes per se.
Configuration changes
Major changes
- There are no major changes. No new options were added. Several
- improvements were made to configure checks.
+ These are the major changes (aside from introducing tiparm_s):
+ * use wide-character (ncursesw) by default
+ * use opaque typedefs by default
+
+ However, most of the work on configure scripts was done to reduce
+ warnings within the configure script:
+ * intrusive warnings from GNU grep regarding fgrep and egrep
+ * fatal errors in compile-checks, arising from recent "Modern C"
+ efforts by some developers which caused longstanding configure
+ checks to fail.
+ After repairing the configure script, none of that activity
+ affected ncurses because stricter warnings are used routinely in
+ development.
+
+ Other improvements made to configure checks include
+ * use string-hacks in alloc_entry.c, alloc_type.c and hardscroll.c,
+ overlooked due to compiler changes in recent OpenBSD releases
+ * revise progs.priv.h to provide for NC_ISATTY reuse
+ * configure check for MB_LEN_MAX provides warning as needed
+ * trim a space after some "-R" options, fixing builds for
+ applications built using clang and ncurses on Solaris
+ * work around misconfiguration of MacPorts gcc13, which exposes
+ invalid definition of MB_LEN_MAX in gcc's fallback copy of
+ limits.h
+ * modified experimental Windows driver works with xterm mouse
+ protocol
Configuration options
- There are a few new/modified configure options:
+ There are a few new configure options:
+
+ --disable-setuid-environ
+ Compile with environment restriction, so certain environment
+ variables are not available when running via a setuid/setgid
+ application. These are (for example $TERMINFO) those that allow
+ the search path for the terminfo or termcap entry to be
+ customized.
+
+ A setuid/setgid application inherits its environment variables
+ from the current user, in contrast to sudo which may limit the
+ environment variables that ncurses uses.
+
+ --enable-check-size
+ Compile-in feature to detect screensize for terminals which do
+ not advertise their screensize, e.g., serial terminals.
+
+ --with-abi-altered=NUM
+ Override the displayed (rather than compiled-in) ABI. Only
+ packagers who have created configurations where the ABI differs
+ from ncurses should be interested in this option.
+
+ --with-strip-program=XXX
+ When stripping executables during install, use the specified
+ program rather than "strip" overriding program chosen by the
+ install program for stripping executables.
- --with-abi-version
- add ABI 7 defaults to configure script.
+ These configure options are modified:
- --with-caps
- add warning in configure script if file specified for
- "--with-caps" does not exist.
+ --with-pkg-config-libdir[=DIR]
+ The optional DIR parameter can now be "auto" to automatically
+ use pkg-config's library directory.
- --with-manpage-format
- bzip2 and xz compression are now supported
+ The default is $(libdir).
- --with-xterm-kbs
- add check/warning in configure script if option
- "--with-xterm-kbs" is missing or inconsistent
+ --with-xterm-kbs[=XXX]
+ The default is "auto" which tells the configure script to
+ choose BS or DEL according to platform defaults.
Portability
Many of the portability changes are implemented via the configure
script:
- * amend configure option's auto-search to account for systems where
- none of the directories known to pkg-config exist
- * corrected regex needed for older pkg-config used in Solaris 10
- * improve handling of --with-pkg-config-libdir option, allowing for
- the case where either $PKG_CONFIG_LIBDIR or the option value has a
- colon-separated list of directories
- * if the --with-pkg-config-libdir option is not given, use
- ${libdir}/pkgconfig as a default
- * improve search-path check for pkg-config, e.g., for Debian testing
- which installs pkg-config with architecture-prefixes.
- * build-fix for cross-compiling to MingW, conditionally add -lssp
- * improve configure check for getttynam
- * fixes to build with dietlibc:
- + add configure check for fpathconf
- + add configure check for math sine/cosine, needed in
- test/tclock, and eliminate pow() from test/hanoi
- + use wcsnlen as an alternative to wmemchr if it is not found
- * modify configure macro CF_BUILD_CC to check if the build-compiler
- works, rather than that it is different from the cross-compiler,
- e.g., to accommodate a compiler which can be used for either
- purpose with different flags
- * modify configure/scripts to work around interference by GNU grep
- 3.8
+ * add/use configure check for clock_gettime, to supersede
+ gettimeofday.
+ * modify configure script check for pkg-config library directory to
+ take into account an older version 0.15.0 which used
+ PKG_CONFIG_PATH but not PKG_CONFIG_LIBDIR
+ * allow for MinGW32-/64-bit configurations to use _DEFAULT_SOURCE
+ * modify CF_XOPEN_SOURCE macro's amend default case to avoid
+ undefining _XOPEN_SOURCE if _POSIX_C_SOURCE is defined
+ * updated configure script macro CF_XOPEN_SOURCE, for uClibc-ng
+ * modify version-check for gcc/g++, now works for msys2
+ * build-fixes related to configure-options and/or platform:
+ + fix for --enable-fvisibility
+ + fix for unusual values of --with-rel-version
+ + fix for unusual values of --with-abi-version
+ + fix for --disable-tcap-names
+ + fix for termcap in nc_access.h
+ * other configure-script improvements:
+ + recent msys2 headers work with _DEFAULT_SOURCE; amend check
+ + use $ac_includes_default in most cases where stdlib.h should
+ work
+ + use #error consistently vs "make an error"
+ + add configure macro for gettimeofday vs inline check
Here are some of the other portability fixes:
- * change man_db.renames to template, to handle ncurses*-config
- script with the --extra-suffix configure option.
- * update CF_XOPEN_SOURCE macro, adding variants "gnueabi" and
- "gnueabihf" to get _DEFAULT_SOURCE special case, as well as adding
- GNU libc suffixes for "abi64", "abin32", "x32" to distinguish it
- from other libc flavors.
- * work around musl's nonstandard use of feature test macros by
- adding a definition for NCURSES_WIDECHAR to the generated ".pc"
- and *-config files.
- * use "command -v" rather than "type" in Ada95/gen/Makefile.in to
- fix a portability issue.
+ * modify configure scripts/makefiles to omit KEY_RESIZE if the
+ corresponding SIGWINCH feature is disabled
+ * increase MB_CUR_MAX to 16, matching glibc's MB_LEN_MAX
+ * add BSD erase2 to characters handled by tset/reset
+ * use getauxval when available, to improve setuid/setgid checks
+ * set dwShareMode in calls to CreateConsoleScreenBuffer
+ * use CreateFile with "CONIN$", "CONOUT$" rather than GetStdHandle
+ to obtain a handle on the actual console, avoiding redirection in
+ the MinGW/Win32 configurations
+ * modify MinGW driver to return KEY_BACKSPACE when an unmodified
+ VK_BACK virtual key is entered
+ * modify MinGW configuration to provide for running in MSYS/MSYS2
+ shells, assuming ConPTY support

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.
+ * ncurses supports the features of SVr4 curses including keyboard
+ mapping, color, form drawing with ACS characters, and automatic
+ recognition of keypad and function keys.
+ * ncurses provides work-alike replacements of SVr4 supplemental
+ libraries based on curses, but which were not specified by X/Open
+ Curses:
+ + the panel library, supporting a stack of windows with backing
+ store
+ + the menu library, supporting a uniform but flexible interface
+ for menu programming
+ the form library, supporting data collection through
- on-screen forms.
+ 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,
+ + ncurses supports user-defined capabilities that 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
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).
+ * 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 almost all 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.
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
- has a corresponding function which may be linked (and will be
- prototype-checked) if the macro definition is disabled with
- #undef.
+ * X/Open Curses permits most functions it specifies to be made
+ available as macros as well. ncurses does this
+ + to improve performance, e.g., for operations composed of
+ simpler functions such as cursor movement following by adding
+ text to the screen,
+ + to simplify the implementation by reusing functions which use
+ common parameters, e.g., the standard screen stdscr, and
+ + to provide functions that return values via their parameters
+ Except for the last case, ncurses provides a non-macro
+ implementation of the function. If the macro definition is
+ disabled with #undef, or by defining NCURSES_NOMACROS the function
+ may be linked (and its calls will be checked against the
+ prototype).
* Extensive documentation is provided (see the Additional Reading
section of the ncurses FAQ for online documentation).

How to install Ncurses/Terminfo on your system
---------------------------------------------------------------------
several builds, some symbols will be listed in the the ".map" files
that do not happen to be present in one configuration or another.
- The sample ".map" (and ".sym") files are generated using a set of
- scripts which build several configurations for each release version,
- checking to see which of the "_nc_" symbols can be made local. In
- addition to the ncurses libraries and programs, the symbols used
- by the "tack" program before version 1.08 are made global.
+ The sample ".map" (and ".sym") files were generated using a set of
+ scripts which built several configurations for each release version,
+ checking to see which of the "_nc_" symbols can be made local.
These sample ".map" files will not cover all possible combinations.
In some cases, e.g., when using the --with-weak-symbols option, you
you may encounter when building a system with different versions of
ncurses:
- 6.5 (TBD; not stable; in development)
+ 6.5 (Apt 27, 2024)
Interface changes:
+ the WINDOW structure and some related internal data types declared
default; and
+ support for wide characters is now enabled by default.
+ Added extensions:
+
+ + is_cbreak, is_echo, is_nl, and is_raw, as well as "_sp" variants
+
+ + tiparm_s and tiscan_s
+
+ Added internal functions (other than "_sp" variants):
+
+ + _nc_env_access
+
+ Removed internal functions:
+
+ + none
+
+ Modified internal functions:
+
+ + These now pass a const parameter: _nc_delink_entry, _nc_str_copy,
+ and _nc_trans_string

<h3><a name="h3-library" id="h3-library">Library improvements</a></h3>
<h4><a name="h4-new-library" id="h4-new-library">New features</a></h4>
- <p>There are no new features in this release.</p>
+ <p>These are new features:</p>
+
+ <ul>
+ <li>
+ <p>The low-level terminfo and termcap interfaces are used
+ both by the higher-level curses library, as well as by many
+ applications.</p>
+
+ <p>The functions which convert parameterized terminal
+ capability strings for output to the terminal
+ (<code>tiparm</code> and <code>tparm</code>) analyze the
+ capability string to determine which parameters are strings
+ (i.e., addresses), versus numbers (not addresses).</p>
+
+ <p>The library's analysis of a capability string may differ
+ from the calling application's design if environment
+ variables are used to point to an invalid terminal database.
+ This is a longstanding problem with <em>all</em>
+ implementations of terminfo, dating from the early 1980s.</p>
+
+ <p>Two new functions address this problem: by providing a
+ function which allows the calling application to tell ncurses
+ how many string-parameters to expect:</p>
+
+ <ul>
+ <li><code>tiscan_s</code> helps applications check
+ formatting capabilities that would be passed to
+ <code>tiparm_s</code>.</li>
+
+ <li><code>tiparm_s</code> provides applications a way to
+ tell ncurses what the expected parameters are for a
+ capability.</li>
+ </ul>
+ </li>
+
+ <li>
+ <p>The ncurses library supports a compile-time feature
+ (enabled with the configure <code>--enable-check-size</code>
+ option) which simplifies initialization with terminals which
+ do not negotiate window (screen) size. This is done in
+ <code>setupterm</code>, by providing for using ANSI
+ cursor-position report (in user6/user7 terminfo capabilities)
+ to obtain the screen size if neither environment variables or
+ ioctl is used.</p>
+
+ <p>The ncurses test-program with options
+ “<code>-E -T</code>” demonstrates this
+ feature.</p>
+ </li>
+
+ <li>add functions to query tty-flags in
+ <code>SCREEN</code></li>
+ </ul>
+
+ <p>This release drops compatibility with obsolete versions of
+ <a href="@HOMEPAGE@/tack/">tack</a>, e.g., pre-1.08</p>
<h4><a name="h4-fixes-library" id="h4-fixes-library">Other
improvements</a></h4>
<ul>
<li>
- <p>modify <tt>delscreen</tt> to more effectively delete all
- windows on the given screen.</p>
+ <p>In addition to the new, safer function
+ <code>tiparm_s</code>, ncurses adds checks to make the older
+ <code>tiparm</code>, <code>tparm</code> and
+ <code>tgoto</code> functions safer:</p>
+
+ <ul>
+ <li>
+ <p>the terminfo functions <code>tiparm</code> and
+ <code>tparm</code> ensure that the capability string
+ comes from the terminal description which ncurses loads,
+ rather than from random data which the application
+ happens to have.</p>
+ </li>
+
+ <li>
+ <p>the <code>tgoto</code> function disallows capabilities
+ which its analysis shows will attempt to use string
+ parameters.</p>
+ </li>
+
+ <li>
+ <p>ncurses uses internal functions which correspond to
+ <code>tiparm</code>, and <code>tgoto</code> which ensure
+ that the capability strings which are passed to these
+ functions come from the loaded terminal description.</p>
+ </li>
+ </ul>
+ </li>
+
+ <li>
+ <p>improve check in <code>lib_tparm.c</code>, ensuring that a
+ char* fits into a <code>TPARM_ARG</code></p>
+ </li>
+
+ <li>
+ <p>modify <code>_nc_syserr_abort</code> to use
+ <code>_nc_env_access</code>, rather than only checking root
+ uid</p>
+ </li>
+
+ <li>
+ <p>improve thread lock in <code>lib_trace.c</code></p>
+ </li>
+
+ <li>
+ <p>modify <code>flushinp</code> to use file descriptors in
+ <code>SCREEN</code>, rather than from <code>TERMINAL</code>,
+ and check if they are for a terminal, like SVr4</p>
+ </li>
+
+ <li>
+ <p>modify <code>mcprint</code> to use file descriptor in
+ <code>SCREEN</code>, for consistency</p>
+ </li>
+
+ <li>
+ <p>modify internal function <code>_nc_read_file_entry</code>
+ to show relevant filename in warnings</p>
</li>
<li>
- <p>modify <tt>wnoutrefresh</tt> to call <tt>pnoutrefresh</tt>
- if its parameter is a pad, rather than treating it as an
- error, and modify new_panel to permit its window-parameter to
- be a pad</p>
+ <p>improve checks in internal function
+ <code>convert_string</code> for corrupt terminfo entry</p>
</li>
<li>
- <p>modify curses_trace() to show the trace-mask as symbols,
- e.g., <tt>TRACE_ORDINARY</tt>, <tt>DEBUG_LEVEL(3)</tt>.</p>
+ <p>review/improve handling of out-of-memory conditions</p>
</li>
<li>
- <p>improve checks for valid mouse events when an intermediate
- mouse state is not part of the mousemask specified by the
- caller</p>
+ <p>limit delays to 30 seconds, i.e., padding delays in
+ terminfo, as well as <code>napms</code> and
+ <code>delay_output</code> functions</p>
</li>
<li>
- <p>allow extended-color number in <em>opts</em> parameter of
- <tt>wattr_on</tt>.</p>
+ <p>fix reallocation loop for <code>vsnprintf</code> in
+ <code>_nc_sprintf_string</code> by copying the va_list
+ variable</p>
</li>
<li>
- <p>improve <tt>_tracecchar_t2</tt> formatting of
- base+combining character.</p>
+ <p>modify <code>delscreen</code> to limit the windows which
+ it creates to just those associated with the screen</p>
</li>
<li>
- <p>trim out some unwanted linker options from ncurses*config
- and .pc files seen in Fedora 36+.</p>
+ <p>modify <code>endwin</code> to return an error if it is
+ called again without an intervening screen update</p>
</li>
<li>
- <p>improve shell-scripts with <em>shellcheck</em></p>
+ <p>modify <code>wenclose</code> to handle pads</p>
</li>
<li>
- <p>improve use of "trap" in shell scripts, using a
- script.</p>
+ <p>eliminate use of <code>PATH_MAX</code> in
+ <code>lib_trace.c</code></p>
</li>
<li>
- <p>modify <tt>make-tar.sh</tt> scripts to make timestamps
- more predictable.</p>
+ <p>provide for any <code>CCHARW_MAX</code> greater than 1</p>
</li>
</ul>
<ul>
<li>
- <p>modify <tt>misc/gen-pkgconfig.in</tt> to allow for the
- case where the library directory does not yet exist, since
- this is processed before doing an install</p>
+ <p>correct loop termination condition in
+ <code>waddnstr</code> and <code>waddnwstr</code></p>
+ </li>
+
+ <li>
+ <p>improve parsing in internal function
+ <code>_nc_msec_cost</code>, allowing a single decimal
+ point</p>
</li>
<li>
- <p>set trailing null on string passed from <tt>winsnstr</tt>
- to <tt>wins_nwstr</tt>.</p>
+ <p>amend parameter check for entire string versus specific
+ length in <code>winsnstr</code> and <code>wins_nwstr</code>
+ to match Solaris; make similar correction to
+ <code>wins_nwstr</code></p>
</li>
<li>
- <p>modify <tt>waddch_literal</tt> to allow for double-width
- base character when merging a combining character</p>
+ <p>correct internal function <code>wadd_wch_literal</code>
+ when adding a non-spacing character to a double-width

<h3><a name="h3-bug-fixes" id="h3-bug-fixes">Interesting
bug-fixes</a></h3>
- <p>While there were many bugs fixed during development of ncurses
- 6.4, 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 <a href=
- "@HOMEPAGE@/NEWS.html#t20221231">NEWS</a> file no elaboration is
- needed here.</p>
+ <p>The changes to <tt>tparm</tt>, <tt>tgoto</tt> which improve
+ the design of the low-level interfaces are <em>interesting</em>,
+ but are not bug-fixes <em>per se</em>.</p>
+
+ <h3><a name="h3-config-config" id=
+ "h3-config-config">Configuration changes</a></h3>
+
+ <h4><a name="h4-config-major" id="h4-config-major">Major
+ changes</a></h4>
- <p>The interesting bugs were those dealing with memory leaks and
- buffer overflows. Although the utilities are designed for
- <em>text</em> files (which they do properly), some choose to test
- them with <strong>non-</strong><em>text</em> files.</p>
+ <p>These are the major changes (aside from introducing <a href=
+ "#h4-new-library"><tt>tiparm_s</tt></a>):</p>
<ul>
<li>
- <p>Text files contain no embedded nulls. Also, they end with
- a newline. Feeding <strong>tic</strong> non-text files
- exposed a few cases where the program did not check for those
- issues. As a result, further processing of the input found
- limit-checks whose assumptions were invalid.</p>
+ <p>use wide-character (ncursesw) by default</p>
</li>
<li>
- <p>Fixing the limit-checks (first) found a problem with
- <strong>tic</strong> managing the list of strings in a
- terminal description. In merging two terminal descriptions
- (i.e., the “use=” feature), <strong>tic</strong>
- was not allocating a complete copy. A quick repair for that
- introduced a memory leak.</p>
+ <p>use opaque typedefs by default</p>
</li>
+ </ul>
+ <p>However, most of the work on configure scripts was done to
+ reduce warnings within the configure script:</p>
+
+ <ul>
<li>
- <p>The checks for non-text files are improved (i.e., embedded
- nulls in the input file will cause <strong>tic</strong> to
- reject it rather than attempting to process it).</p>
+ <p>intrusive warnings from GNU grep regarding fgrep and
+ egrep</p>
</li>
<li>
- <p>The string allocations in <strong>tic</strong> are
- likewise improved.</p>
+ <p>fatal errors in compile-checks, arising from recent
+ “Modern C” efforts by some developers which
+ caused longstanding configure checks to fail.</p>
+
+ <p>After repairing the configure script, none of that
+ activity affected ncurses because stricter warnings are used
+ routinely in development.</p>
</li>
</ul>

- <p>There are no major changes. No new options were added. Several
- improvements were made to configure checks.</p>

<h3><a name="h3-library" id="h3-library">Library improvements</a></h3>
<h4><a name="h4-new-library" id="h4-new-library">New features</a></h4>
- <p>There are no new features in this release.</p>
+ <p>These are new features:</p>
+
+ <ul>
+ <li>
+ <p>The low-level terminfo and termcap interfaces are used
+ both by the higher-level curses library, as well as by many
+ applications.</p>
+
+ <p>The functions which convert parameterized terminal
+ capability strings for output to the terminal
+ (<code>tiparm</code> and <code>tparm</code>) analyze the
+ capability string to determine which parameters are strings
+ (i.e., addresses), versus numbers (not addresses).</p>
+
+ <p>The library's analysis of a capability string may differ
+ from the calling application's design if environment
+ variables are used to point to an invalid terminal database.
+ This is a longstanding problem with <em>all</em>
+ implementations of terminfo, dating from the early 1980s.</p>
+
+ <p>Two new functions address this problem: by providing a
+ function which allows the calling application to tell ncurses
+ how many string-parameters to expect:</p>
+
+ <ul>
+ <li><code>tiscan_s</code> helps applications check
+ formatting capabilities that would be passed to
+ <code>tiparm_s</code>.</li>
+
+ <li><code>tiparm_s</code> provides applications a way to
+ tell ncurses what the expected parameters are for a
+ capability.</li>
+ </ul>
+ </li>
+
+ <li>
+ <p>The ncurses library supports a compile-time feature
+ (enabled with the configure <code>--enable-check-size</code>
+ option) which simplifies initialization with terminals which
+ do not negotiate window (screen) size. This is done in
+ <code>setupterm</code>, by providing for using ANSI
+ cursor-position report (in user6/user7 terminfo capabilities)
+ to obtain the screen size if neither environment variables or
+ ioctl is used.</p>
+
+ <p>The ncurses test-program with options
+ “<code>-E -T</code>” demonstrates this
+ feature.</p>
+ </li>
+
+ <li>add functions to query tty-flags in
+ <code>SCREEN</code></li>
+ </ul>
+
+ <p>This release drops compatibility with obsolete versions of
+ <a href="https://invisible-island.net/ncurses/tack/">tack</a>, e.g., pre-1.08</p>
<h4><a name="h4-fixes-library" id="h4-fixes-library">Other
improvements</a></h4>
<ul>
<li>
- <p>modify <tt>delscreen</tt> to more effectively delete all
- windows on the given screen.</p>
+ <p>In addition to the new, safer function
+ <code>tiparm_s</code>, ncurses adds checks to make the older
+ <code>tiparm</code>, <code>tparm</code> and
+ <code>tgoto</code> functions safer:</p>
+
+ <ul>
+ <li>
+ <p>the terminfo functions <code>tiparm</code> and
+ <code>tparm</code> ensure that the capability string
+ comes from the terminal description which ncurses loads,
+ rather than from random data which the application
+ happens to have.</p>
+ </li>
+
+ <li>
+ <p>the <code>tgoto</code> function disallows capabilities
+ which its analysis shows will attempt to use string
+ parameters.</p>
+ </li>
+
+ <li>
+ <p>ncurses uses internal functions which correspond to
+ <code>tiparm</code>, and <code>tgoto</code> which ensure
+ that the capability strings which are passed to these
+ functions come from the loaded terminal description.</p>
+ </li>
+ </ul>
+ </li>
+
+ <li>
+ <p>improve check in <code>lib_tparm.c</code>, ensuring that a
+ char* fits into a <code>TPARM_ARG</code></p>
+ </li>
+
+ <li>
+ <p>modify <code>_nc_syserr_abort</code> to use
+ <code>_nc_env_access</code>, rather than only checking root
+ uid</p>
+ </li>
+
+ <li>
+ <p>improve thread lock in <code>lib_trace.c</code></p>
+ </li>
+
+ <li>
+ <p>modify <code>flushinp</code> to use file descriptors in
+ <code>SCREEN</code>, rather than from <code>TERMINAL</code>,
+ and check if they are for a terminal, like SVr4</p>
+ </li>
+
+ <li>
+ <p>modify <code>mcprint</code> to use file descriptor in
+ <code>SCREEN</code>, for consistency</p>
+ </li>
+
+ <li>
+ <p>modify internal function <code>_nc_read_file_entry</code>
+ to show relevant filename in warnings</p>
</li>
<li>
- <p>modify <tt>wnoutrefresh</tt> to call <tt>pnoutrefresh</tt>
- if its parameter is a pad, rather than treating it as an
- error, and modify new_panel to permit its window-parameter to
- be a pad</p>
+ <p>improve checks in internal function
+ <code>convert_string</code> for corrupt terminfo entry</p>
</li>
<li>
- <p>modify curses_trace() to show the trace-mask as symbols,
- e.g., <tt>TRACE_ORDINARY</tt>, <tt>DEBUG_LEVEL(3)</tt>.</p>
+ <p>review/improve handling of out-of-memory conditions</p>
</li>
<li>
- <p>improve checks for valid mouse events when an intermediate
- mouse state is not part of the mousemask specified by the
- caller</p>
+ <p>limit delays to 30 seconds, i.e., padding delays in
+ terminfo, as well as <code>napms</code> and
+ <code>delay_output</code> functions</p>
</li>
<li>
- <p>allow extended-color number in <em>opts</em> parameter of
- <tt>wattr_on</tt>.</p>
+ <p>fix reallocation loop for <code>vsnprintf</code> in
+ <code>_nc_sprintf_string</code> by copying the va_list
+ variable</p>
</li>
<li>
- <p>improve <tt>_tracecchar_t2</tt> formatting of
- base+combining character.</p>
+ <p>modify <code>delscreen</code> to limit the windows which
+ it creates to just those associated with the screen</p>
</li>
<li>
- <p>trim out some unwanted linker options from ncurses*config
- and .pc files seen in Fedora 36+.</p>
+ <p>modify <code>endwin</code> to return an error if it is
+ called again without an intervening screen update</p>
</li>
<li>
- <p>improve shell-scripts with <em>shellcheck</em></p>
+ <p>modify <code>wenclose</code> to handle pads</p>
</li>
<li>
- <p>improve use of "trap" in shell scripts, using a
- script.</p>
+ <p>eliminate use of <code>PATH_MAX</code> in
+ <code>lib_trace.c</code></p>
</li>
<li>
- <p>modify <tt>make-tar.sh</tt> scripts to make timestamps
- more predictable.</p>
+ <p>provide for any <code>CCHARW_MAX</code> greater than 1</p>
</li>
</ul>
<ul>
<li>
- <p>modify <tt>misc/gen-pkgconfig.in</tt> to allow for the
- case where the library directory does not yet exist, since
- this is processed before doing an install</p>
+ <p>correct loop termination condition in
+ <code>waddnstr</code> and <code>waddnwstr</code></p>
+ </li>
+
+ <li>
+ <p>improve parsing in internal function

<h3><a name="h3-bug-fixes" id="h3-bug-fixes">Interesting
bug-fixes</a></h3>
- <p>While there were many bugs fixed during development of ncurses
- 6.4, 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 <a href=
- "https://invisible-island.net/ncurses/NEWS.html#t20221231">NEWS</a> file no elaboration is
- needed here.</p>
+ <p>The changes to <tt>tparm</tt>, <tt>tgoto</tt> which improve
+ the design of the low-level interfaces are <em>interesting</em>,
+ but are not bug-fixes <em>per se</em>.</p>
+
+ <h3><a name="h3-config-config" id=
+ "h3-config-config">Configuration changes</a></h3>
+
+ <h4><a name="h4-config-major" id="h4-config-major">Major
+ changes</a></h4>
- <p>The interesting bugs were those dealing with memory leaks and
- buffer overflows. Although the utilities are designed for
- <em>text</em> files (which they do properly), some choose to test
- them with <strong>non-</strong><em>text</em> files.</p>
+ <p>These are the major changes (aside from introducing <a href=
+ "#h4-new-library"><tt>tiparm_s</tt></a>):</p>
<ul>
<li>
- <p>Text files contain no embedded nulls. Also, they end with
- a newline. Feeding <strong>tic</strong> non-text files
- exposed a few cases where the program did not check for those
- issues. As a result, further processing of the input found
- limit-checks whose assumptions were invalid.</p>
+ <p>use wide-character (ncursesw) by default</p>
</li>
<li>
- <p>Fixing the limit-checks (first) found a problem with
- <strong>tic</strong> managing the list of strings in a
- terminal description. In merging two terminal descriptions
- (i.e., the “use=” feature), <strong>tic</strong>
- was not allocating a complete copy. A quick repair for that
- introduced a memory leak.</p>
+ <p>use opaque typedefs by default</p>
</li>
+ </ul>
+ <p>However, most of the work on configure scripts was done to
+ reduce warnings within the configure script:</p>
+
+ <ul>
<li>
- <p>The checks for non-text files are improved (i.e., embedded
- nulls in the input file will cause <strong>tic</strong> to
- reject it rather than attempting to process it).</p>
+ <p>intrusive warnings from GNU grep regarding fgrep and
+ egrep</p>
</li>
<li>
- <p>The string allocations in <strong>tic</strong> are
- likewise improved.</p>
+ <p>fatal errors in compile-checks, arising from recent
+ “Modern C” efforts by some developers which
+ caused longstanding configure checks to fail.</p>
+
+ <p>After repairing the configure script, none of that
+ activity affected ncurses because stricter warnings are used
+ routinely in development.</p>
</li>
</ul>
- <h3><a name="h3-config-config" id=

+ <p>Other improvements made to configure checks include</p>
- <h4><a name="h4-config-major" id="h4-config-major">Major
- changes</a></h4>
+ <ul>
+ <li>
+ <p>use <a href=
+ "https://invisible-island.net/ncurses/INSTALL.html#option:enable-string-hacks">string-hacks</a>
+ in alloc_entry.c, alloc_type.c and hardscroll.c, overlooked
+ due to compiler changes in recent OpenBSD releases</p>
+ </li>

+ </li>
+
+ <li>
+ <p>trim a space after some "-R" options, fixing builds for
+ applications built using clang and ncurses on Solaris</p>
+ </li>
- <p>There are no major changes. No new options were added. Several
- improvements were made to configure checks.</p>
+ <li>
+ <p>work around misconfiguration of MacPorts gcc13, which
+ exposes invalid definition of <tt>MB_LEN_MAX</tt> in gcc's
+ fallback copy of <tt>limits.h</tt></p>

.SH DESCRIPTION
-These routines delete the character under the cursor; all characters to the
-right of the cursor on the same line are moved to the left one position and the
-last character on the line is filled with a blank.
-The cursor position does
-not change (after moving to \fIy\fP, \fIx\fP, if specified).
-(This does not
-imply use of the hardware delete character feature.)
+.B \%wdelch
+deletes the character at the cursor position in
+.IR win .
+\fB\%ncurses\fP(3X) describes the variants of this function.
+.PP
+.B \%wdelch
+moves all characters to the right of the cursor on the same line to the

+the line with the window's blank character;
+see \fB\%bkgd\fP(3X)
+(wide-character API users may consult \fB\%bkgrnd\fP(3X) instead).
+The cursor position does not change
+(after moving to

.SH RETURN VALUE
-All routines return the integer \fBERR\fP upon failure and an \fBOK\fP
-(SVr4 specifies only
-\*(``an integer value other than \fBERR\fP\*('')
-upon successful completion.
+These functions return

+ * This is an updated version of Markus Kuhn's implementation of wcwidth.
+ *
+ * Originally added to xterm in 2000 (patch #141), there were a couple of
+ * updates from Kuhn until 2005 (patch #202), renaming entrypoints and applying
+ * data from Unicode.org (e.g., 3.2, 4.0, 4.1.0). The Unicode data is
+ * transformed into tables in this file by a script "uniset" written by Kuhn.
+ *
+ * While Kuhn implemented the original CJK variant, it was unused by xterm
+ * until Jungshik Shin used it in 2002 to implement the -cjk_width command-line
+ * option.
+ *
+ * Kuhn added a check for the vertical forms block (double-width) in 2007;
+ * other updates were derived from the Unicode.org data (release 5.0).
+ *
+ * Since then, additional updates have been made:
+ * + data-type fixes
+ * + new Unicode releases (6.2.0, 9.0.0, etc),
+ * + additional special symbol blocks have been added to the special cases.
+ * + soft-hyphen behavior has been made configurable.
+ * + added table shows when a character is not part of Unicode.
+ *
+ * Kuhn's original header follows giving the design information:
