+ modify "-T" option of clear and tput to call use_tioctl() to obtain
the operating system's notion of the screensize if possible.
+ review/repair some exit-codes for tput, making usage-message exit
with 2 rather than 1, and a failure to open terminal 4+errno.
+ amend check in tput, tabs and clear to allow those to use the
database-only features in cron if a -T option gives a suitable
terminal name (report by Lauri Tirkkonen).
+ correct an ifdef in test/ncurses.c for systems with soft-keys but
not slk_color().
+ regenerate man-html documentation.
+ fix a symbol conflict that made ncurses.c C/c menu not work with
Solaris xpg4 curses.
+ add refresh() call to dots_mvcur.c, needed to use mvcur() with
Solaris xpg4 curses after calling newterm().
+ minor fixes for configure script from work on ncurses-examples and
tin.
+ improve animation in test/xmas.c by adding a time-delay in blinkit().
+ modify several test programs to reflect that ncurses honors existing
signal handlers in initscr(), while other implementations do not.
+ modify bs.c to make it easier to quit.
+ change ncurses-examples to use attr_t vs chtype to follow X/Open
documentation more closely since Solaris xpg4-curses uses different
values for WA_xxx vs A_xxx that rely on attr_t being an unsigned
short. Tru64 aka OSF1, HPUX, AIX did as ncurses does, equating the
two sets.
+ modify menu for test/ncurses.c to fit on 24-line screen.
+ build-fix for configure --with-caps=uwin
+ add options to test_arrays.c, for selecting termcap vs terminfo, etc.
+ improve wide-character implementation of myADDNSTR() in frm_driver.c,
which was inconsistent with the normal implementation.
+ save/restore cursor position in Undo_Justification(), matching
behavior of Buffer_To_Window() (report by Leon Winter).
+ modify test/knight to provide the "slow" solution for small screens
using "R", noting that Warnsdorf's method is easily done with "a".
+ modify several test-programs which call use_default_colors() to
consistently do this only if "-d" option is given.
+ additional changes to test with non-standard variants of curses:
+ modify a loop limit in firework.c to work around absense of limit
checks in some libraries.
+ fill the last row of a window with "?" in firstlast if waddch does
not return ERR on the lower-right corner.
+ add checks in test/configure for some functions not in 4.3BSD curses.
+ fix a regression in test/configure (cf: 20170826).
+ amend change for endwin-state for better consistency with the older
logic (report/patch by Jeb Rosen, cf: 20170722).
+ modify check in fmt_entry() to handle a cancelled reset string
(Debian #873746). Make similar fixes in other parts of dump_entry.c
and tput.c
+ fixes for "iterm2" (report by Leonardo Brondani Schenkel) -TD
+ corrected a warning from tic about keys which are the same, to skip
over missing/cancelled values.
+ add check in tic for unnecessary use of "2" to denote a shifted
special key.
+ improve checks in trim_sgr0, comp_parse.c and parse_entry.c, for
cancelled string capabilities.
+ add check in _nc_parse_entry() for invalid entry name, setting the
name to "invalid" to avoid problems storing entries.
+ add/improve checks in tic's parser to address invalid input
+ add a check in comp_scan.c to handle the special case where a
nontext file ending with a NUL rather than newline is given to tic
as input (Redhat #1484274).
+ allow for cancelled capabilities in _nc_save_str (Redhat #1484276).
+ add validity checks for "use=" target in _nc_parse_entry (Redhat
#1484284).
+ check for invalid strings in postprocess_termcap (Redhat #1484285)
+ reset secondary pointers on EOF in next_char() (Redhat #1484287).
+ guard _nc_safe_strcpy() and _nc_safe_strcat() against calls using
cancelled strings (Redhat #1484291).
+ correct typo in curs_memleaks.3x (Sven Joachim).
+ improve test/configure checks for some curses variants not based on
X/Open Curses.
+ add options for test/configure to disable checks for form, menu and
panel libraries.
+ update "iterm" entry -TD
+ add "iterm2" entry (report by Leonardo Brondani Schenkel) -TD
+ regenerate llib-* files.
+ regenerate HTML manpages.
+ improve picsmap test-program:
+ reduce memory used for tsearch
+ add report in log file showing cumulative color coverage.
+ add -x option to clear/tput to make the E3 extension optional
(cf: 20130622).
+ add options -T and -V to clear command for compatibility with tput.
+ add usage message to clear command (Debian #371855).
+ improve usage messages for tset and tput.
+ minor fixes to "RDGB" extension and reset_color_pairs().
+ improve description of -R option in infocmp manual page (report by
Stephane Chazelas).
+ add reset_color_pairs() function.
+ add user_caps.5 manual page to document the terminfo extensions used
by ncurses.
+ improve build scripts, using SIGQUIT vs SIGTRAP; add other configure
script fixes from work on xterm, lynx and tack.
+ modify install-rule for ncurses-examples to put the data files in
/usr/share/ncurses-examples
+ improve tracemunch, by changing address-parameters of add_wch(),
color_content() and pair_content() to dummy parameters.
+ minor optimization to _nc_change_pair, to return quickly when the
current screen is marked for clearing.
+ in-progress changes to improve performance of test/picsmap.c for
loading image files.
+ modify allocation for SCREEN's color-pair table to start small, grow
on demand up to the existing limit.
+ add "RGB" extension capability for direct-color support, use this to
improve color_content().
+ improve picsmap test-program:
+ if no palette file is needed, attempt to load one based on $TERM,
checking first in the current directory, then by adding ".dat"
suffix, and finally in the data-directory, e.g.,
/usr/share/ncurses-examples
+ add "-l" option for logging
+ add "-d" option for debugging
+ add "-s" option for stepping automatically through list of images,
with time delay.
+ use tsearch to improve time for loading color table for images.
+ update config.guess, config.sub from
http://git.savannah.gnu.org/cgit/config.git
+ update interix entry using tack and SFU on Windows 7 Ultimate -TD
+ use ^? for kdch1 in interix (reported by Jonathan de Boyne Pollard)
+ add "rep" to xterm-new, available since 1997/01/26 -TD
+ move SGR 24 and 27 from vte-2014 to vte-2012 (request by Alain
Williams) -TD
+ add a check in newline_forces_scroll() in case a program moves the
cursor outside scrolling margins (report by Robert King).
+ improve _nc_tparm_analyze, using that to extend the checks made by
tic for reporting inconsistencies between the expected number of
parameters for a capability and the actual.
+ amend handling of repeat_char capability in EmitRange (adapted from
report/patch by Dick Wesseling):
+ translate the character to the alternate character set when the
alternate character set is enabled.
+ do not use repeat_char for characters past 255.
+ document "_nc_free_tinfo" in manual page, because it could be used in
tack for memory-leak checking.
+ add "--without-tack" configure option to refine "--with-progs"
configure option. Normally tack is no longer built in-tree, but
a few packagers combine it during the build. If term_entry.h is
installed, there is no advantage to in-tree builds.
+ adjust configure-script to define HAVE_CURSES_DATA_BOOLNAMES symbol
needed for tack 1.08 when built in-tree. Rather than relying upon
internal "_nc_" functions, tack now uses the boolean, number and
string capability name-arrays provided by ncurses and SVr4 Unix
curses. It still uses term_entry.h for the definitions of the
extended capability arrays.
+ add an overlooked null-pointer check in mvcur changes from 20170722
+ improve test-packages for ncurses-examples and AdaCurses for lintian
+ modify logic for endwin-state to be able to detect the case where
the screen was never initialized, using that to trigger a flush of
ncurses' buffer for mvcur, e.g., in test/dots_mvcur.c for the
term-driver configuration.
+ add dependency upon ncurses_cfg.h to a few other internal header
files to allow each to be compiled separately.
+ add dependency upon ncurses_cfg.h to tic's header-files; any program
using tic-library will have to supply this file. Legacy tack
versions supply this file; ongoing tack development has dropped the
dependency upon tic-library and new releases will not be affected.
+ modify command-line parameters for "convert" used in picsmap to work
with ImageMagick 6.8 and newer.
+ fix build-problem with tack and ABI-5 (Debian #868328).
+ repair termcap-format from tic/infocmp broken in 20170701 fixes
(Debian #868266).
+ reformat terminfo.src with 20170513 updates.
+ improve test-packages to address lintian warnings.
+ modify update_getenv() in db_iterator.c to ensure that environment
variables which are not initially set will be checked later if an
application happens to set them (patch by Guillaume Maudoux).
+ remove initialization-check for calling napms() in the term-driver
configuration; none is needed.
+ add help-screen to test/test_getstr.c and test/test_get_wstr.c
+ improve compatibility between different configurations of new_prescr,
fixing a case with threaded code and term-driver where c++/demo did
not work (cf: 20160213).
+ the fixes for Redhat #1464685 obscured a problem subsequently
reported in Redhat #1464687; the given test-case was no longer
reproducible. Testing without the fixes for the earlier reports
showed a problem with buffer overflow in dump_entry.c, which is
addressed by reducing the use of a fixed-size buffer.
+ add/improve checks in tic's parser to address invalid input
(Redhat #1464684, #1464685, #1464686, #1464691).
+ alloc_entry.c, add a check for a null-pointer.
+ parse_entry.c, add several checks for valid pointers as well as
one check to ensure that a single character on a line is not
treated as the 2-character termcap short-name.
+ fix a memory leak in delscreen() (report by Bai Junq).
+ improve tracemunch, showing thread identifiers as names.
+ fix a use-after-free in NCursesMenu::~NCursesMenu()
+ further amend incorrect calls for memory-leaks from 20170617 changes
(report by Allen Hewes).
+ modify c++/etip.h.in to accommodate deprecation of throw() and
throws() in c++17 (prompted by patch by Romain Geissler).
+ remove some incorrect calls for memory-leaks from 20170617 changes
(report by Allen Hewes).
+ add test-programs for termattrs and term_attrs.
+ modify _nc_outc_wrapper to use the standard output if the screen was
not initialized, rather than returning an error.
+ improve checks for low-level terminfo functions when the terminal
has not been initialized (Redhat #1345963).
+ modify make_hash to allow building with address-sanitizer,
assuming that --disable-leaks is configured.
+ amend changes for number_format() in 20170506 to avoid undefined
behavior when shifting (patch by Emanuele Giaquinta).
+ fill in some places where TERMTYPE2 vs TERMTYPE was not used
(report by Allen Hewes).
+ use ExitTerminfo() internally in error-exits for ncurses' setupterm
to help with leak checking.
+ use ExitProgram() in error-exit from initscr() to help with leak
checking.
+ review test-programs, adding checks for cases where the terminal
cannot be initialized.
+ add option "-xp" to picsmap.c, to use init_extended_pair().
+ make simple performance fixes for picsmap.c
+ improve aspect ratio of images read from "convert" in picsmap.c
+ add option to picsmap to use color-palette files, e.g., for mapping
to xterm-256color.
+ move the data in SCREEN used for the alloc_pair() function to the
end, to restore compatibility between ncurses/ncursesw libtinfo
(report/patch by Miroslav Lichvar).
+ add build-time utility "report_offsets" to help show when the various
configurations of tinfo library are compatible or not.
+ improved test/picsmap.c:
+ lookup named colors for xpm files in rgb.txt
+ accept blanks in color-keys for xpm files.
+ if neither xbm/xpm work, try "convert", which may be available.
+ modify test/picsmap.c to read xpm files.
+ modify package/debian/* to create documentation packages, so the
related files can be checked with lintian.
+ fix some typos in manpages (report/patch by Sven Joachim).
+ add test/picsmap.c to fill in some testing issues not met by dots.
The initial version reads X bitmap (".xbm") files.
+ repair logic which forces a repaint where a color-pair's content is
changed (cf: 20170311).
+ improve tracemunch, showing screenXX pointers as names.
+ modify tic/infocmp display of numeric values to use hexadecimal when
they are "close" to a power of two, making the result more readable.
+ improve discussion of portability in curs_mouse.3x
+ change line-length for generated html/manpages to 78 columns from 65.
+ improve discussion of line-drawing characters in curs_add_wch.3x
(prompted by discussion with Lorinczy Zsigmond).
+ cleanup formatting of hackguide.html and ncurses-intro.html
+ add examples for WACS_D_PLUS and WACS_T_PLUS to test/ncurses.c
+ corrected a case where $with_gpm was set to "maybe" after CF_WITH_GPM,
overlooked in 20160528 fixes (report by Alexandre Bury).
+ improve a couple of test-program's help-messages.
+ corrected loop in rain.c from 20170415 changes.
+ modify winnstr and winchnstr to return error if the output pointer is
null, as well as adding a null pointer check of the window pointer
for better compatibility with other implementations.
+ improve discussion of NetBSD curses in scr_dump.5
+ modify LIMIT_TYPED macro in new_pair.h to avoid changing sign of the
value to be limited (reports by Darby Payne, Rob Boudreau).
+ update config.guess, config.sub from
http://git.savannah.gnu.org/cgit/config.git
+ build-fix for termcap-configuration (report by Chi-Hsuan Yen).
+ improve terminfo manual page discussion of control- and graphics-
characters.
+ remove tic warning about "^?" in string capabilities, which was
marked as an extension (cf: 20000610, 20110820); however all Unix
implementations support this and X/Open Curses does not address it.
On the other hand, termcap never did support this feature.
+ correct missing comma-separator between string capabilities in
icl6402 and m2-nam -TD
+ restore rmir/smir in ansi+idc to better match original ansiterm+idc,
add alias ansiterm (report by Robert King).
+ amend an old check for ambiguous use of "ma" in terminfo versus
a termcap use, if the capability is cancelled to treat it as number.
+ correct a case in _nc_captoinfo() which read "%%" and emitted "%".
+ modify sscanf calls in _nc_infotocap() for patterns "%{number}%+%c"
and "%'char'%+%c" to check that the final character is really 'c',
avoiding a case in icl6404 which cannot be converted to termcap.
+ in _nc_infotocap(), add a check to ensure that terminfo "^?" is not
written to termcap, because the BSDs did not implement that.
+ in _nc_tic_expand() and _nc_infotocap(), improve string-length check
when deciding whether to use "^X" or "\xxx" format for control
characters, to make the output of tic/infocmp more predictable.
+ limit termcap "%d" width to 2 digits on input, and use "%2" in
preference to "%02" on output.
+ correct terminfo/termcap conversion of "%02" and "%03" into "%2" and
"%3"; the result repeated the last character.
+ add man/scr_dump.5 to document screen-dump format.
+ modify several test programs to use new popup_msgs, adapted from
help-screen used in test/edit_field.c
+ drop two symbols obsoleted in 2004: _nc_check_termtype, and
_nc_resolve_uses
+ fix some old copyright dates (cf: 20031025).
+ build-fixes for test/savescreen.c to work with AIX and HPUX.
+ minor fix to configure script, adding a backslash/continuation.
+ extend TERMINAL structure for ABI 6 to store numbers internally as
integers rather than short, by adding new data for this purpose.
+ more fixes for minor memory-leaks in test-programs.
+ change logic in wins_nwstr() to avoid addressing data past the output
of mbstowcs().
+ correct a call to setcchar() in Data_Entry_w() from 20131207 changes.
+ fix minor memory-leaks in test-programs.
+ further improve ifdef in term_entry.h for internal definitions not
used by tack.
+ minor fixes for vt100+4bsd, e.g., delay in sgr for consistency -TD
+ add smso for env230, to match sgr -TD
+ remove p7/protect from sgr in fbterm -TD
+ drop setf/setb from fbterm; setaf/setab are enough -TD
+ make xterm-pcolor sgr consistent with other capabilities -TD
+ add rmxx/smxx ECMA-48 strikeout extension to tmux and xterm-basic
(discussion with Nicholas Marriott)
+ add test-programs sp_tinfo and extended_color
+ modify no-leaks code for lib_cur_term.c to account for the tgetent()
cache.
+ modify setupterm() to save original tty-modes so that erasechar()
works as expected. Also modify _nc_setupscreen() to avoid redundant
calls to get original tty-modes.
+ modify set_curterm() to update ttytype[] data used by longname().
+ modify wattr_set() and wattr_get() to return ERR if win-parameter is
null, as documented.
+ improve cast used for null-pointer checks in header macros, to
reduce compiler warnings.
+ modify several functions, using the reserved "opts" parameter to pass
color- and pair-values larger than 16-bits:
+ getcchar(), setcchar(), slk_attr_set(), vid_puts(), wattr_get(),
wattr_set(), wchgat(), wcolor_set().
+ Other functions call these with the corresponding altered behavior,
including chgat(), mvchgat(), mvwchgat(), slk_color_on(),
slk_color_off(), vid_attr().
+ add new functions for manipulating color- and pair-values larger
than 16-bits. These are extended_color_content(),
extended_pair_content(), extended_slk_color(), init_extended_color(),
init_extended_pair(), and the corresponding sp-funcs.
+ fix a memory leak in the window-list when creating multiple screens
(reports by Andres Martinelli, Debian #783486).
+ reviewed calls from link_test.c, added a few more null-pointer
checks.
+ add a null-pointer check in ungetmouse, in case mousemask was not
called (report by "Kau").
+ updated curs_sp_funcs.3x for new functions.
+ change TERMINAL structure in term.h to make it opaque. Some
applications misuse its members, e.g., directly modifying it
rather than using def_prog_mode().
+ modify utility headers such as tic.h to make it clearer which are
externals that are used by tack.
+ improve curs_slk.3x in particular its discussion of portability.
+ fix cut/paste in legacy_encoding.3x
+ add prototype for find_pair() to new_pair.3x (report by Branden
Robinson).
+ fix a couple of broken links in generated man-html documentation.
+ regenerate man-html documentation.
+ modify vt100 rs2 string to reset vt52 mode and scrolling regions
(report/analysis by Robert King) -TD
+ add vt100+4bsd building block, use that for older terminals rather
than "vt100" which is now mostly used as a building block for
terminal emulators -TD
+ correct a few spelling errors in terminfo.src comments -TD
+ add fbterm -TD
+ fix a typo in ncurses.c test_attr legend (patch by Petr Vanek).
+ changed internal colorpair_t to a struct, eliminating an internal
8-bit limit on colors
+ add ncurses/new_pair.h
+ add ncurses/base/new_pair.c with alloc_pair(), find_pair() and
free_pair() functions
+ add test/demo_new_pair.c
+ improve terminfo manual description of terminfo syntax.
+ clarify the use of wint_t vs wchar_t in curs_get_wstr.3x
+ improve description of endwin() in manual.
+ modify setcchar() and getcchar() to treat negative color-pair as an
error.
+ fix a typo in include/hashed_db.h (Andre Sa).
+ fix several formatting issues with manual pages.
+ correct read of terminfo entry in which all strings are absent or
explicitly cancelled. Before this fix, the result was that all were
treated as only absent.
+ modify infocmp to suppress mixture of absent/cancelled capabilities
that would only show as "NULL, NULL", unless the -q option is used,
e.g., to show "-, @" or "@, -".
+ build-fixes for PGI compilers (report by Adam J. Stewart)
+ accept whitespace in sed expression for generating expanded.c
+ modify configure check that g++ compiler warnings are not used.
+ add configure check for -fPIC option needed for shared libraries.
+ let configure --disable-ext-funcs override the default for the
--enable-sp-funcs option.
+ mark some structs in form/menu/panel libraries as potentially opaque
without modifying API/ABI.
+ add configure option --enable-opaque-curses for ncurses library and
similar options for the other libraries.
+ trim newlines, tabs and escaped newlines from terminfo "paths" passed
to db-iterator.
+ ignore zero-length files in db-iterator; these are useful for
instance to suppress "$HOME/.terminfo" when not wanted.
+ amended "b64:" encoder to work with the terminfo reader.
+ modify terminfo reader to accept "b64:" format using RFC-3548 in
as well as RFC-4648 url/filename-safe format.
+ modify terminfo reader to accept "hex:" format as generated by
"infocmp -0qQ1" (cf: 20150905).
+ adjust authors comment to reflect drop below 1% for SV.
+ minor comment-fixes to help automate links to bug-urls -TD
+ add dvtm, dvtm-256color -TD
+ add settings corresponding to xterm-keys option to tmux entry to
reflect upcoming change to make that option "on" by default
(patch by Nicholas Marriott).
+ uncancel Ms in tmux entry (Harry Gindi, Nicholas Marriott).
+ add dumb-emacs-ansi -TD
+ improve discussion of early history of tput program.
+ incorporate A_COLOR mask into COLOR_PAIR(), in case user application
provides an out-of-range pair number (report by Elijah Stone).
+ clarify description in tput manual page regarding support for
termcap names (prompted by FreeBSD #214709).
+ remove a restriction in tput's support for termcap names which
omitted capabilities normally not shown in termcap translations
(cf: 990123).
+ modify configure script for clang as used on FreeBSD, to work around
clang's differences in exit codes vs gcc.
+ improve discussion of early history of tset/reset programs.
+ clarify in manual pages that the optional verbose option level is
available only when ncurses is configured for tracing.
+ amend change from 20161231 to avoid writing traces to the standard
error after initializing the trace feature using the environment
variable.
+ amend changes for tput to reset tty modes to "sane" if the program
is run as "reset", like tset. Likewise, ensure that tset sends
either reset- or init-strings.
+ improve manual page descriptions of tput init/reset and tset/reset,
to make it easier to see how they are similar and different.
+ move a static result from key_name() to _nc_globals
+ modify _nc_get_screensize to allow for use_env() and use_tioctl()
state to be per-screen when sp-funcs are configured, better matching
the behavior when using the term-driver configuration.
+ improve cross-references in manual pages for often used functions
+ move SCREEN field for use_tioctl() data before the ncursesw fields,
and limit that to the sp-funcs configuration to improve termlib
compatibility (cf: 20120714).
+ correct order of initialization for traces in use_env() and
use_tioctl() versus first trace calls.
+ fix errata for ncurses-howto (report by Damien Ruscoe).
+ fix a few places in configure/build scripts where DESTDIR and rpath
were combined (report by Thomas Klausner).
+ merge current st description (report by Harry Gindi) -TD
+ modify flash capability for linux and wyse entries to put the delay
between the reverse/normal escapes rather than after -TD
+ modify program tabs to pass the actual tty file descriptor to
setupterm rather than the standard output, making padding work
consistently.
+ explain in clear's manual page that it writes to stdout.
+ add special case for verbose debugging traces of command-line
utilities which write to stderr (cf: 20161126).
+ remove a trace with literal escapes from skip_DECSCNM(), added in
20161203.
+ update config.guess, config.sub from
http://git.savannah.gnu.org/cgit/config.git
+ correct parmeters for copywin call in _nc_Synchronize_Attributes()
(patch by Leon Winter).
+ improve color-handling section in terminfo manual page (prompted by
patch by Mihail Konev).
+ modify programs clear, tput and tset to pass the actual tty file
descriptor to setupterm rather than the standard output, making
padding work.
+ add tput-colorcube demo script.
+ add -r and -s options to tput-initc demo, to match usage in xterm.
+ flush the standard output in _nc_flush for the case where SP is zero,
e.g., when called via putp. This fixes a scenario where "tput flash"
did not work after changes in 20130112.
+ add configure script option --disable-wattr-macros for use in cases
where one wants to use the same headers for ncurses5/ncurses6
development, by suppressing the wattr* macros which differ due to
the introduction of extended colors (prompted by comments in
Debian #230990, Redhat #1270534).
+ add test/tput-initc to demonstrate tput used to initialize palette
from a data file.
+ modify test/xterm*.dat to use the newer color4/color12 values.
+ modify linux-16color to not mask dim, standout or reverse with the
ncv capability -TD
+ add 0.1sec mandatory delay to flash capabilities using the VT100
reverse-video control -TD
+ omit selection of ISO-8859-1 for G0 in enacs capability from linux2.6
entry, to avoid conflict with the user-defined mapping. The reset
feature will use ISO-8859-1 in any case (Mikulas Patocka).
+ improve check in tic for delays by also warning about beep/flash
when a delay is not embedded, or if those use the VT100 reverse
video escape without using a delay.
+ minor fix for syntax-check of delays from 20161119 changes.
+ modify trace() to avoid overwriting existing file (report by Maor
Shwartz).
+ improve -W option in tic/infocmp:
+ correct order of size-adjustments in wrapped lines
+ if -f option splits line, do not further split it with -W
+ begin a new line when adding "use=" after a wrapped line
