- change-log since ncurses 5.6 release.
-
- Interface changes:
- * generate linkable stubs for some macros:
- getattrs
-
- New features and improvements:
- * library
- + new flavor of the ncurses library provides rudimentary
- support for POSIX threads. Several functions are reentrant,
- but most require either a window-level or screen-level mutex.
- (This is API-compatible, but not ABI-compatible with the
- normal library).
- + add NCURSES_OPAQUE symbol to curses.h, will use to make
- structs opaque in selected configurations.
- + add NCURSES_EXT_FUNCS and NCURSES_EXT_COLORS symbols to
- curses.h to make it simpler to tell if the extended functions
- and/or colors are declared.
- + add wresize() to C++ binding
- + eliminate fixed-buffer vsprintf() calls in C++ binding.
- + add several functions to C++ binding which wrap C functions
- that pass a WINDOW* parameter.
- + adapt mouse-handling code from menu library in form-library
- + improve tracing for form library, showing created forms,
- fields, etc.
- + make $NCURSES_NO_PADDING feature work for termcap interface .
- + add check to trace-file open, if the given name is a
- directory, add ".log" to the name and try again.
- + several new manpages: curs_legacy.3x, curs_memleaks.3x,
- curs_opaque.3x and curs_threads.3x
- * programs:
- + modified three test-programs to demonstrate the threading
- support in this version: ditto, rain, worm.
- + several new test-programs: demo_panels, dots_mvcur,
- inch_wide, inchs, key_name, key_names, savescreen,
- savescreen.sh test_arrays, test_get_wstr, test_getstr,
- test_instr, test_inwstr and test_opaque.
- + add adacurses-config to the Ada95 install.
- + modify tic -f option to format spaces as \s to prevent them
- from being lost when that is read back in unformatted
- strings.
- + The tack program is now distributed separately from ncurses.
- * terminal database
- + added entries:
- o Eterm-256color, Eterm-88color and rxvt-88color
- o aterm
- o konsole-256color
- o mrxvt
- o screen.mlterm
- o screen.rxvt
- o teraterm4.59 is now the primary primary teraterm entry,
- renamed original to teraterm2.3
- o 9term terminal
- o Newbury Data entries
- + updated/improved entries:
- o gnome to version 2.22.3
- o h19, z100
- o konsole to version 1.6.6
- o mlterm, mlterm+pcfkeys
- o xterm, and building-blocks for function-keys to [3]xterm
- patch #230.
-
- Major bug fixes:
- * add logic to tic for cancelling strings in user-defined
- capabilities (this is needed for current konsole terminfo entry).
- * modify mk-1st.awk so the generated makefile rules for linking or
- installing shared libraries do not first remove the library, in
- case it is in use, e.g., libncurses.so by /bin/sh.
- * correct check for notimeout() in wgetch().
- * fix a sign-extension bug in infocmp's repair_acsc() function.
- * change winnstr() to stop at the end of the line.
- * make Ada95 demo_panels() example work.
- * fix for adding a non-spacing character at the beginning of a line.
- * fill in extended-color pair to make colors work for
- wide-characters using extended-colors.
- * improve refresh of window on top of multi-column characters,
- taking into account split characters on left/right window
- boundaries.
- * modify win_wchnstr() to ensure that only a base cell is returned
- for each multi-column character.
- * improve waddch() and winsch() handling of EILSEQ from mbrtowc() by
- using unctrl() to display illegal bytes rather than trying to
- append further bytes to make up a valid sequence.
- * restore curs_set() state after endwin()/refresh()
- * modify keyname() to use "^X" form only if meta() has been called,
- or if keyname() is called without initializing curses, e.g., via
- initscr() or newterm().
- * modify unctrl() to check codes in 128-255 range versus isprint().
- If they are not printable, and locale was set, use a "M-" or "~"
- sequence.
- * improve resizeterm() by moving ripped-off lines, and repainting
- the soft-keys.
- * modify form library to accept control characters such as newline
- in set_field_buffer(), which is compatible with Solaris.
- * use NCURSES_MOUSE_MASK() in definition of BUTTON_RELEASE(), etc.,
- to make those work properly with the --enable-ext-mouse
- configuration
- * correct some functions in Ada95 binding which were using return
- value from C where none was returned.
- * reviewed/fixed issues reported by Coverity and Klocwork tools.
-
- Portability:
+ 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.
+ * add tiparm, based on review of X/Open Curses Issue 7.
+
+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.
+ + update minix terminfo entry.
+ + updated nsterm* entries.
+ + remove unnecessary kcan assignment to ^C from putty.
+ + suppress ncv in screen and konsole-base entries, allowing
+ underline.
+ + change ncv and op capabilities in sun-color terminfo entry to
+ 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
