- change-log since ncurses 5.7 release.
-
-Interface changes
-
- * turn on _XOPEN_CURSES definition in curses.h.
- * change _nc_has_mouse to has_mouse, reflect its use in C++ and
- Ada95.
- * add is_pad and is_subwin functions for opaque access to the WINDOW
- structure.

-
-New features and improvements
-
- Library Improvements
-
- * add a terminal driver for Windows console, which supports a MinGW
- port to Windows.
- * add extended functions which specify the SCREEN pointer for
- several curses functions which use the global SP.
- * improve the NCURSES_NO_UTF8_ACS feature by adding a check for an
- extended terminfo capability U8.
- * improve performance of tigetstr, etc., by using hashing code from
- tic.
- * add WACS_xxx definitions to wide-character configuration for
- thick- and double-lines.
- * modify init_pair to allow caller to create extra color pairs
- beyond the color_pairs limit, which use default colors.
-
- Improvements to Programs
-
- * add tabs program.
- * modify tic's -I/-C dump to reformat acsc strings into canonical
- form (sorted, unique mapping).
- * add checks in tic for inconsistent cursor-movement controls, and
- for inconsistent printer-controls.
- * add special case to _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.
-
- Terminal Database
-
- * added entries:
- + bterm terminfo entry, based on bogl 0.1.18
- + cons25-debian entry
- + eterm-color entry
- + linux-16color
- + mlterm+256color entry, for mlterm 3.0.0
- + several screen-bce.xxx entries
- + screen.Eterm terminfo entry
- + vwmterm entry
- + xterm-utf8 entry as a demo of the U8 feature
- * updated/improved entries:
- + use extended capabilities:
- o add U8 feature to denote entries for terminal emulators
- which do not support VT100 SI/SO when processing UTF-8
- encoding
- o add XT capability to entries for terminals that support
- both xterm-style mouse- and title-controls, for screen
- which special-cases TERM beginning with xterm or rxvt
- + improvements based on new checks in tic:
- +
- o fill in no-parameter forms of cursor-movement where a
- parameterized form is available
- o fill in missing cursor controls where the form of the
- controls is ANSI
- o add parameterized cursor-controls to linux-basic
- o modify nsterm, xnuppc and tek4115 to make sgr/sgr0
- consistent
- o change several terminfo entries to make consistent use
- of ANSI clear-all-tabs
- + extend ansi.sys pfkey capability from kf1-kf10 to kf1-kf48,
- moving function key definitions from emx-base for
- consistency.
- + correct missing final 'p' in pfkey capability of
- ansi.sys-old.
- + rename atari and st52 terminfo entries to atari-old,
- st52-old, use newer entries from FreeMiNT.
- + repurpose gnome terminfo entries as vte, retaining gnome
- variants for compatibility, but generally deprecating those
- since the VTE library is what actually defines the behavior
- of "gnome", etc., since 2003.
- + improve interix smso terminfo capability by using reverse
- rather than bold.
- + correct initc capability of linux-c-nc end-of-range, make
- similar change for dg+ccc and dgunix+ccc.

- match Sun's entry for this.
- + fix typo in rmso for tek4106 entry.
- + improve acsc string for vt52, show arrow keys.
- + add hard-reset for rs2 to wsvt25 to help ensure that reset
- ends the alternate character set.
- + add ccc and initc capabilities to xterm-16color.
-
-Major bug fixes
-
- * ncurses library
- + wide character support
- o modify length returned by getcchar to count the trailing
- null which is documented in X/Open.
- o fix an infinite recursion when adding a legacy-coding
- 8-bit value using insch.
- o improve a workaround in adding wide-characters, when a
- control character is found. The library uses unctrl to
- obtain a printable version of the control character, but
- was not passing color or video attributes.
- o modify waddch_literal, updating line-pointer after a
- multicolumn character is found to not fit on the current
- row, and wrapping is done. Since the line-pointer was
- not updated, the wrapped multicolumn character was
- written to the beginning of the current row.
- o fixes in wins_nwstr and related functions to ensure that
- special characters, i.e., control characters are handled
- properly with the wide-character configuration.
- o correct internal _nc_insert_ch to use _nc_insert_wch
- when inserting wide characters, since the wins_wch
- function that it used did not update the cursor
- position.
- + mouse
- o add check if Gpm_Open returns a -2, e.g., for "xterm".
- This is normally suppressed but can be overridden using
- $NCURSES_GPM_TERMS. Ensure that Gpm_Close is called in
- this case.
- o add check in mouse-driver to disable connection if GPM
- returns a zero, indicating that the connection is
- closed.
- o modify getmouse to act as its documentation implied,
- returning on each call the preceding event until none
- are left. When no more events remain, it will return
- ERR.
- + miscellaneous
- o improve handling of color-pairs embedded in attributes
- for the extended-colors configuration.
- o add check for failure to open hashed-database needed for
- db4.6.
- o modify use of $CC environment variable which is defined
- by X/Open as a curses feature, to ignore it if it is not
- a single character.
- o modify declaration of cur_term when broken-linker is
- used, but enable-reentrant is not, to match pre-5.7.
- o correct limit-checks in derwin.
- o remove old check in mvderwin which prevented moving a
- derived window whose origin happened to coincide with
- its parent's origin.
- o correct limit-checks in newwin, to ensure that windows
- have nonzero size.
- o modify set_curterm to make broken-linker configuration
- work with changes from 20090228.
- o modify wgetch to ensure it checks SIGWINCH when it gets
- an error in non-blocking mode.
- o correct limit-check in wredrawln, accounting for
- begy/begx values.
- o fix a null-pointer check in _nc_format_slks in
- lib_slk.c, from 20070704 changes.
- o correct translation of "^" in _nc_infotocap, used to
- transform terminfo to termcap strings.
- o modify _nc_wgetch to check for a -1 in the fifo, e.g.,
- after a SIGWINCH, and discard that value, to avoid
- confusing application.
- * other libraries
- + correct transfer of multicolumn characters in multirow
- field_buffer, which stopped at the end of the first row due
- to filling of unused entries in a cchar_t array with nulls.
- + correct buffer-size after internal resizing of wide-character
- set_field_buffer, broken in 20081018 changes.
- + correct layout of working window used to extract data in
- wide-character configured by set_field_buffer
-
-Portability
-
- * configure script:
- + new options:
-
- --disable-libtool-version
- use the "-version-number" feature which was added
- in libtool 1.5. The default value for the option
- uses the newer feature, which makes libraries
- generated using libtool compatible with the
- standard builds of ncurses.
-
- --disable-rpath-hack
- disable a feature which adds rpath options for
- libraries in unusual places.
-
- --enable-interop
- integrate changes for generic/interop support to
- form-library.
-
- --enable-pc-files
- generate ".pc" files for each of the libraries, and
- install them in pkg-config's library directory.
-
- --enable-pthreads-eintr
- control whether to allow EINTR to interrupt a read
- operation in wgetch. This applies only to the
- pthread configuration
-
- --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.
-
- --enable-term-driver
- compile with terminal-driver. That is used in the
- MinGW port, and (being somewhat more complicated)
- is an experimental alternative to the conventional
- termlib internals. Currently, it requires the
- sp-funcs feature to be enabled.
-
- --with-ncurses-wrap-prefix
- allows setting the prefix for functions used to
- wrap global variables to something other than
- "_nc_".
-
- --with-pkg-config=[DIR]
- check for pkg-config, optionally specifying its
- path.
-
- --without-manpages
- tells the configure script to suppress the install
- of ncurses' manpages.
-
- --without-tests
- suppress building test programs.
-
- + improved options:
- o correct logic for --with-database, which was coded as an
- enable-type switch.
- o omit the opaque-functions from lib_gen.o when
- --disable-ext-funcs is used.
- * packaging:
- + *-config scripts:
- o modify adacurses-config to look for ".ali" files in the
- adalib directory.
- o correct install for the Ada95 tree, which omitted
- libAdaCurses.a used in adacurses-config.
- o change install for adacurses-config to provide
- additional flavors such as adacursesw-config, for
- ncursesw.
- o modify scripts to generate ncurses*-config and pc-files
- to add dependency for tinfo library.
- o use ncurses*-config scripts if available for
- test/configure.
- o correct name for termlib in ncurses*-config, e.g., if it
- is renamed to provide a single file for ncurses/ncursesw
- libraries.
- o generate manpages for the *-config scripts, adapted from
- help2man.
- o modify install-rule for manpages so that *-config
- manpages will install when building with --srcdir.
- o build-fixes for OpenSolaris aka Solaris 11, for
- wide-character configuration as well as for rpath
- feature in *-config scripts.
- o use $includedir symbol in misc/ncurses-config.in, add
- --includedir option.
- o improve install-rules for pc-files.
- o create the pkg-config library directory if needed.
- o fix typo "==" where "=" is needed in ncurses-config.in
- and gen-pkgconfig.in files.
- o modify 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.
- o modify handling of $PKG_CONFIG_LIBDIR to use only the
- first item in a possibly colon-separated list.
- + other packaging issues
- o add make-tar.sh scripts to Ada95 and test subdirectories
- to help with making those separately distributable.
- o add Ada95/configure script, to use in tar-file created
- by Ada95/make-tar.sh.
- o remove tar-copy.sh and related configure/Makefile
- chunks, since the Ada95 binding is now installed using
- rules in Ada95/src.
- * cross-compiling:
- + improve configure checks for location of tic and infocmp
- programs used for installing database and for generating
- fallback data, e.g., for cross-compiling.
- + modify #define's for build-compiler to suppress cchar_t
- symbol from compile of make_hash and make_keys, improving
- cross-compilation of ncursesw.
- + simplify include-dependencies of make_hash and make_keys, to
- reduce the need for setting BUILD_CPPFLAGS in cross-compiling
- when the build- and target-machines differ.
- + correct cross-compiling configure check for CF_MKSTEMP macro,
- by adding a check cache variable set by AC_CHECK_FUNC.
- * library dependencies:
- + revise wadd_wch and wecho_wchar to eliminate dependency on
- unctrl.
- + adjust configure script so that "t" is not added to library
- suffix when weak-symbols are used, allowing the pthread
- configuration to more closely match the non-thread naming.
- * building the Ada95 tree:
- + changes to use gnatmake project files in the Ada95 tree.
- + add/use configure check to turn on project rules for
- Ada95/src.
- + old gnatmake (3.15) does not produce libraries using
- project-file; work around by adding script to generate
- alternate makefile.
- + add configure --with-ada-sharedlib option, for the test_make
- rule.
- + move Ada95-related logic into aclocal.m4, since additional
- checks will be needed to distinguish old/new implementations
- of gnat.
- + add test_make / test_clean / test_install rules in Ada95/src
- + change install-path for adainclude directory to
- /usr/share/ada (was /usr/lib/ada).
- * other configure/build issues:
- + make CCHARW_MAX value configurable, noting that changing this
- would change the size of cchar_t, and would be
- ABI-incompatible.
- + improve comparison of program-names when checking for linked
- flavors such as "reset" by ignoring the executable suffix.
- + drop mkdirs.sh, use "mkdir -p".
- + drop misc/ncu-indent and misc/jpf-indent; they are provided
- by an external package [3]cindent.
- + change makefiles to use $ARFLAGS rather than $AR_OPTS,
- provide a configure check to detect whether a "-" is needed
- before "ar" options.
- + modify CF_DISABLE_LEAKS configure macro so that the
- --enable-leaks option is not the same as --disable-leaks.
- + improve configure script macros CF_HEADER_PATH and
- CF_LIBRARY_PATH by adding CFLAGS, CPPFLAGS and LDFLAGS, LIBS
- values to the search-lists.
- + improve configure macros 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.
- + modify CF_WITH_LIBTOOL configure check to allow unreleased
- libtool version numbers (e.g. which include alphabetic chars,
- as well as digits, after the final '.').
- + improve use of symbolic links in makefiles by using "-f"
- option if it is supported, to eliminate temporary removal of
- the target
- + add a configure-time check to pick a suitable value for
- CC_SHARED_OPTS for Solaris.
- + add -shared option to MK_SHARED_LIB when -Bsharable is used,
- for *BSD's, without which "main" might be one of the shared
- library's dependencies.
- + modify configure script to allow building shared libraries
- with gcc on AIX 5 or 6.
- + suppress configure check for static/dynamic linker flags for
- gcc on Solaris 10, since gcc is confused by absence of static
- libc, and does not switch back to dynamic mode before
- finishing the libraries.
- + suppress configure check for static/dynamic linker flags for
- gcc on Darwin.
- + modify misc/run_tic.in to create parent directory, in case
- this is a new install of hashed database.
- + modify configure check for tic program, used for fallbacks,
- to a warning if not found. This makes it simpler to use
- additonal scripts to bootstrap the fallbacks code using tic
- from the build tree.
- * test programs:
- + add test/demo_terminfo, for comparison with demo_termcap.
- + improve test/ncurses.c 'F' test, show combining characters in
- color.
- + fix logic for 'V' in test/ncurses.c tests f/F.
- + improve test/ncurses.c 'a test to put mouse droppings in the
- proper window.
- + modify ncurses 'F' test to demo wborder_set with colored
- lines.
- + modify ncurses 'f' test to demo wborder with colored lines.
- + improve test/ncurses.c 'a' test, using unctrl more
- consistently to display meta-characters.
- + correct use of key_name in test/ncurses.c 'A' test, which
- only displays wide-characters, not key-codes since 20070612.
- + add test/clip_printw.c to illustrate how to use printw
- without wrapping.
- + modify test-programs, e.g,. test/view.c, to address subtle
- differences between Tru64/Solaris and HPUX/AIX getcchar
- return values.
- + add some test programs (and make these use the same special
- keys by sharing linedata.h functions): test/test_addstr.c
- test/test_addwstr.c test/test_addchstr.c
- test/test_add_wchstr.c
- + add test/xterm-256color.dat
- + modify test programs to allow them to be built with NetBSD
- curses.
- + fixes for test programs to build/work on HPUX and AIX, etc.
