- change-log since ncurses 5.5 release.
-
- Interface changes:
- * generate linkable stubs for some macros:
- getbegx, getbegy, getcurx, getcury, getmaxx, getmaxy, getparx,
- getpary, getpary,
- and (for libncursesw)
- wgetbkgrnd
-
- New features and improvements:
- * library
- + support hashed databases for the terminal descriptions. This
- uses the Berkeley database, has been tested for several
- versions on different platforms.
- + add use_legacy_coding() function to support lynx's
- font-switching feature.
- + add extension nofilter(), to cancel a prior filter() call.
- + add/install a package config script, e.g., ncurses5-config or
- ncursesw5-config, according to configuration options.
- + provide ifdef for NCURSES_NOMACROS which suppresses most
- macro definitions from curses.h, i.e., where a macro is
- defined to override a function to improve performance.
- + make ifdef's consistent in curses.h for the extended colors
- so the header file can be used for the normal curses library.
- The header file installed for extended colors is a variation
- of the wide-character configuration.
- + improve tgetstr() by making the return value point into the
- user's buffer, if provided.
- + add ifdef's allowing ncurses to be built with tparm() using
- either varargs (the existing status), or using a
- fixed-parameter list (to match X/Open).
- + widen the test for xterm kmous a little to allow for other
- strings than "\E[M", e.g., for xterm-sco functionality in
- xterm.
- + modify wgetnstr() to return KEY_RESIZE if a sigwinch occurs.
- + move prototypes for wide-character trace functions from
- curses.tail to curses.wide to avoid accidental reference to
- those if _XOPEN_SOURCE_EXTENDED is defined without ensuring
- that <wchar.h> is included.
- + change the way shared libraries (other than libtool) are
- installed. Rather than copying the build-tree's libraries,
- link the shared objects into the install directory. This
- makes the --with-rpath option work except with $(DESTDIR).
- + several improvements for rendering in hpterm. These are only
- available if the library is configured using
- --enable-xmc-glitch.
- + Add NCURSES_NO_HARD_TABS and NCURSES_NO_MAGIC_COOKIE
- environment variables to allow runtime suppression of the
- related hard-tabs and xmc-glitch features.
- * programs:
- + add new test programs: chgat.c, demo_altkeys.c, echochar.c,
- foldkeys.c, movewindow.c, redraw.c, (noting that existing
- test programs also were modified to test additional
- features).
- + modify tack to test extended capability function-key strings.
- + modify toe to access termcap data, e.g., via cgetent()
- functions, or as a text file if those are not available.
- + improve infocmp/tic -f option formatting.
- + add toe -a option, to show all databases. This uses new
- private interfaces in the ncurses library for iterating
- through the list of databases.
- + modify MKfallback.sh to use tic -x when constructing fallback
- tables to allow extended capabilities to be retrieved from a
- fallback entry.
- * terminal database
- + add terminfo entries for xfce terminal (xfce) and multi gnome
- terminal (mgt)
- + add nsterm-16color entry
- + updated mlterm terminfo entry
- + add kon, kon2 and jfbterm terminfo entry
- + remove invis capability from klone+sgr, mainly used by linux
- entry, since it does not really do this
- + add ka2, kb1, kb3, kc2 to vt220-keypad as an extension
- + add shifted up/down arrow codes to xterm-new as kind/kri
- strings
- + add hpterm-color terminfo entry
- + add 256color variants of terminfo entries for programs which
- are reported to implement this feature
- + correct order of use-clauses in rxvt-basic entry which made
- codes for f1-f4 vt100-style rather than vt220-style.
-
- Major bug fixes:
- * correct a typo in configure --with-bool option for the case where
- --without-cxx is used.
- * move assignment from environment variable ESCDELAY from initscr()
- down to newterm() so the environment variable affects timeouts for
- terminals opened with newterm() as well.
- * modify werase to clear multicolumn characters that extend into a
- derived window.
- * modify wchgat() to mark updated cells as changed so a refresh will
- repaint those cells.
- * correct logic in wadd_wch() and wecho_wch(), which did not guard
- against passing the multi-column attribute into a call on
- waddch(), e.g., using data returned by win_wch()
- * fix redrawing of windows other than stdscr using wredrawln() by
- touching the corresponding rows in curscr.
- * reduce memory leaks in repeated calls to tgetent() by remembering
- the last TERMINAL* value allocated to hold the corresponding data
- and freeing that if the tgetent() result buffer is the same as the
- previous call.
- * modify read_termtype() so the term_names data is always allocated
- as part of the str_table, a better fix for a memory leak.
- * fix wins_nwstr(), which did not handle single-column non-8bit
- codes.
- * modify wbkgrnd() to avoid clearing the A_CHARTEXT attribute bits
- since those record the state of multicolumn characters.
- * improve SIGWINCH handling by postponing its effect during
- newterm(), etc., when allocating screens.
- * remove 970913 feature for copying subwindows as they are moved in
- mvwin().
- * add checks in waddchnstr() and wadd_wchnstr() to stop copying when
- a null character is found.
- * add some checks to ensure current position is within scrolling
- region before scrolling on a new line.
- * add a workaround to ACS mapping to allow applications such as
- test/blue.c to use the "PC ROM" characters by masking them with
- A_ALTCHARSET. This worked up til 5.5, but was lost in the revision
- of legacy coding.
-
- Portability:
- * configure script:
- + new options:
-
- --with-hashed-db
- Use Berkeley hashed database for storing terminfo
- data rather than storing each compiled entry in a
- separate binary file within a directory tree.
-
- --without-dlsym
- Do not use dlsym() to load GPM dynamically.
-
- --with-valgrind
- Simplify building for testing with valgrind.
-
- --enable-wgetch-events
- Compile with experimental wgetch-events code.
-
- --enable-signed-char
- Store booleans in "signed char" rather than "char".
-
- + improved options:
-
- --disable-largefile
- make the option work both ways.
-
- --with-gpm
- The option now accepts a parameter, i.e., the name
- of the dynamic GPM library to load via dlopen()
-
- --disable-symlinks
- The option now allows one to disable symlink() in
- tic even when link() does not work.
-
- * other configure/build issues:
- + remove special case for Darwin in CF_XOPEN_SOURCE configure
- macro.
- + add configure check to ensure that SIGWINCH is defined on
- platforms such as OS X which exclude that when _XOPEN_SOURCE,
- etc., are defined
- + use ld's -search_paths_first option on Darwin to work around
- odd search rules on that platform.
- + improve ifdef's for _POSIX_VDISABLE in tset to work with Mac
- OS X.
- + modify configure script to ensure that if the C compiler is
- used rather than the loader in making shared libraries, the
- $(CFLAGS) variable is also used.
- + use ${CC} rather than ${LD} in shared library rules for
- IRIX64, Solaris to help ensure that initialization sections
- are provided for extra linkage requirements, e.g., of C++
- applications.
- + improve some shared-library configure scripting for Linux,
- FreeBSD and NetBSD to make --with-shlib-version work.
- + split up dependency of names.c and codes.c in
- ncurses/Makefile to work with parallel make.
- + modify MKlib_gen.sh to change preprocessor-expanded _Bool
- back to bool.
- + modify progs/Makefile.in to make tput init work properly with
- cygwin, i.e., do not pass a .exe in the reference string used
- in check_aliases.
- * library:
- + ignore wide-acs line-drawing characters that wcwidth() claims
- are not one-column. This is a workaround for Solaris' broken
- locale support.
- + reduce name-pollution in term.h by removing #define's for
- HAVE_xxx symbols.
- + fix #ifdef in c++/internal.h for QNX 6.1
- * test programs:
- + modify test/configure script to allow building test programs
- with PDCurses/X11.
- + modified test programs to allow some to work with NetBSD
- curses. Several do not because NetBSD curses implements a
- subset of X/Open curses, and also lacks much of SVr4
- additions. But it is enough for comparison.
- + improved test/configure to build test/ncurses on HPUX 11
- using the vendor curses.
- + change configure script to produce test/Makefile from data
- file.
