The ncurses (new curses) library is a free software emulation of curses in System V - Release 4.0, 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 SYSV-curses - enhancements over BSD curses. + 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 became the basis of + 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. -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!
+Since 1995, ncurses has been + ported to many systems:
-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.
+The ncurses distribution is available via anonymous FTP at the
- GNU distribution site ftp://ftp.gnu.org/gnu/ncurses/ .
+
The distribution includes the library and support utilities, + including

-This release is designed to be source-compatible with + ncurses 5.0 through 6.3; 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 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.
+ +There are no new features in this release.
+ +These are improvements to existing features:
tabs program.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.
+_nc_infotocap (used by tic
- and infocmp) to recognize the
- setaf/setab strings from
- xterm+256color and xterm+88color, and
- provide a reduced version which works with termcap.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.
+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

+update external links in Ada95.html
+EINTR to
- interrupt a read operation in wgetch. This
- applies only to the pthread configurationThere are no new manual pages (all of the manual page updates + are to existing pages).
-SCREEN pointer, reducing the need
- for juggling the global SP value with
- set_term and delscreen.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.
+_nc_".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.
+pkg-config, optionally
- specifying its path.There are no major changes. No new options were added. Several + improvements were made to configure checks.
-There are a few new/modified configure options:
---with-database,
- which was coded as an enable-type switch.add ABI 7 defaults to configure script.
+lib_gen.o when
- --disable-ext-funcs is used.add warning in configure script if file specified for + “--with-caps” does not exist.
+bzip2 and xz compression are now supported
+add check/warning in configure script if option + “--with-xterm-kbs” is missing or + inconsistent
+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
+adacurses-config to look for
- ".ali" files in the adalib directory.if the --with-pkg-config-libdir option is not + given, use ${libdir}/pkgconfig as a default
+libAdaCurses.a used in
- adacurses-config.improve search-path check for pkg-config, e.g., + for Debian testing which installs pkg-config with + architecture-prefixes.
+adacurses-config to
- provide additional flavors such as
- adacursesw-config, for ncursesw.build-fix for cross-compiling to MingW, conditionally add + -lssp
+ncurses*-config and pc-files to add
- dependency for tinfo library.improve configure check for getttynam
+ncurses*-config scripts if
- available for test/configure.fixes to build with dietlibc:
-ncurses*-config, e.g., if it is renamed to
- provide a single file for ncurses/ncursesw
- libraries.help2man.--srcdir.modify configure macro CF_BUILD_CC to check if + the build-compiler works, rather than that it is different + from the cross-compiler, e.g., to accommodate a compiler + which can be used for either purpose with different flags
+$includedir symbol in
- misc/ncurses-config.in, add
- --includedir option.modify configure/scripts to work around interference by + GNU grep 3.8
+Here are some of the other portability fixes:
-pkg-config library
- directory if needed.change man_db.renames to template, to handle + ncurses*-config script with the + --extra-suffix configure option.
+==" where "="
- is needed in ncurses-config.in and
- gen-pkgconfig.in files.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.
+gen-pkgconfig.in to eliminate a
- dependency on rpath when deciding whether to add
- $LIBS to --libs output; that
- should be shown for the ncurses and tinfo libraries
- without taking rpath into account.work around musl's nonstandard use of feature + test macros by adding a definition for + NCURSES_WIDECHAR to the generated “.pc” + and *-config files.
+$PKG_CONFIG_LIBDIR
- to use only the first item in a possibly
- colon-separated list.use “command -v” rather than + “type” in Ada95/gen/Makefile.in + to fix a portability issue.
+make-tar.sh scripts to Ada95 and
- test subdirectories to help with making those
- separately distributable.Ada95/configure script, to use in
- tar-file created by
- Ada95/make-tar.sh.The ncurses package is fully + upward-compatible with SVr4 (System V Release 4) curses:
-tar-copy.sh and related
- configure/Makefile chunks, since the Ada95
- binding is now installed using rules in
- Ada95/src.All of the SVr4 calls have been implemented (and are + documented).
+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:
make_hash and
- make_keys, improving cross-compilation of
- ncursesw.make_hash
- and make_keys, to reduce the need for setting
- BUILD_CPPFLAGS in cross-compiling when the build- and
- target-machines differ.CF_MKSTEMP macro, by adding a check cache
- variable set by AC_CHECK_FUNC.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
+ncurses's terminal database + is fully compatible with that used by SVr4 curses.
wadd_wch and
- wecho_wchar to eliminate dependency on
- unctrl.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 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:
-Ada95/src.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.
CCHARW_MAX value configurable, noting
- that changing this would change the size of
- cchar_t, and would be ABI-incompatible.mkdirs.sh, use
- "mkdir -p".misc/ncu-indent and
- misc/jpf-indent; they are provided by an
- external package cindent.$ARFLAGS rather
- than $AR_OPTS, provide a configure check to
- detect whether a "-" is needed before "ar" options.CF_DISABLE_LEAKS configure macro so
- that the --enable-leaks option is not the same as
- --disable-leaks.CF_HEADER_PATH and
- CF_LIBRARY_PATH by adding CFLAGS,
- CPPFLAGS and LDFLAGS,
- LIBS values to the search-lists.CF_GCC_VERSION
- and CF_GCC_WARNINGS to work with gcc 4.x's c89
- alias, which gives warning messages for cases where older
- versions would produce an error.CF_WITH_LIBTOOL configure check to
- allow unreleased libtool version numbers (e.g. which
- include alphabetic chars, as well as digits, after the
- final '.').-f" option if it is supported, to eliminate
- temporary removal of the targetCC_SHARED_OPTS for Solaris.MK_SHARED_LIB when
- -Bsharable is used, for *BSD's, without which "main" might
- be one of the shared library's dependencies.misc/run_tic.in to create parent
- directory, in case this is a new install of hashed
- database.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 direct-color terminals, such as modern + xterm.
+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.
+key_name in test/ncurses.c
- 'A' test, which only displays wide-characters, not
- key-codes since 20070612.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.)
+linedata.h functions):
- test/test_addstr.c test/test_addwstr.c test/test_addchstr.c
- test/test_add_wchstr.cIn 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 X/Open Curses requirement that every
+ function declared in a header file has a macro equivalent.
+ If the macro definition is disabled with #undef,
+ 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).
The ncurses distribution + includes a selection of test programs (including a few games). + These are available separately as ncurses-examples
-The ncurses library has been tested with a wide variety of + applications including:
