+ > merge branch begun April 2, 2017 which provides these features:
+ + support read/write new binary-format for terminfo which stores
+ numeric capabilities as a signed 32-bit integer. The test programs
+ such as picsmap, ncurses were created or updated during 2017 to use
+ this feature.
+ + the new format is written by the wide-character configuration of
+ tic when it finds a numeric capability larger than 32767.
+ + other applications such as infocmp built with the wide-character
+ ncurses library work as expected.
+ + applications built with the "narrow" (8-bit) configuration will
+ read the new format, but will limit those extended values to 32767.
+ + in either wide/narrow configuration, the structure defined in
+ term.h still uses signed 16-bit values.
+ + because it is incompatible with the legacy (mid-1980s) binary format,
+ a new magic value is provided for the "file" program.
+ + the term.5 manual page is updated to describe this new format.
+ + the limit on file-size for compiled terminfo is increased in the
+ wide-character configuration to 32768.
+
+20180120
+ + build-fix in picsmap.c for stdint.h existence.
+ + add --disable-stripping option to configure scripts.
+ + modify ncurses-examples to install test-scripts in the data directory.
+ + work around tool-breakage in Debian 9 and later by invoking
+ gprconfig to specify the C compiler to be used by gnatmake,
+ and conditionally suppressing Library_Options line for static
+ libraries.
+ + bump the compat level for test-packages to 7, i.e., Debian 5.
+
+20180106
+ + fixes for writing extended color pairs in putwin.
+ + modify test/savescreen.c to add test patterns that exercise 88-,
+ 256-, etc., colors.
+ + modify configure option --with-build-cc, adding clang, c89 and c99
+ as possible default values.
+ + modify ncurses-examples configure script to use pkg-config for the
+ extra form/menu/panel libraries, to be more consistent with the
+ handling of the curses/ncurses library.
+ + modify test-packages for mingw to supply "pc" files.
+ + modify gen-pkgconfig.in to list -lpthread as a private library when
+ configured to access it via weak symbols.
+ + simplify gen-pkgconfig.in, adding -ltinfo without the special linker
+ checks because some versions of the linker simply hard-code the

+ + update URLs for ncurses website to use https.
+ + modify CF_CURSES_LIBS to fill in $cf_nculib_root in case the
+ ncurses-examples are built with a system ncurses that lacks the

+
+20171230

+ directly using the loader (report by Jeffrey Walton).
+ + set ABI for upcoming 6.1 release in "*.map" files. While there are
+ some remaining internals to apply, no ABI-related changes are

+ + build-fix for ncurses-examples with NetBSD curses:

+20171014
+ + minor cleanup to test/view.c:

+ + modify demo_new_pair.c to pass extended pairs to setcchar().
+ + add test/dots_xcurses.c to illustrate a different approach used for
+ extended colors which can be contrasted with dots_curses.c.
+ + add a check in tic to note when a description uses non-mandatory

+ for a terminal emulator may use the combination incorrectly.
+
+20171007
+ + modify "-T" option of clear and tput to call use_tioctl() to obtain

+ + 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

+ two sets.
+
+20170923

+
+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.
+
+20170715
+ + modify command-line parameters for "convert" used in picsmap to work
+ with ImageMagick 6.8 and newer.

+ 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).

+ + 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).

+ + 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).
+
+20170617
+ + 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
+
+20170603
+ + 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.
+
+20170527
+ + 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.
+
+20170520
+ + 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).
+
+20170513
+ + 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.
+
+20170506
+ + modify tic/infocmp display of numeric values to use hexadecimal when

+ + improve a couple of test-program's help-messages.
+ + corrected loop in rain.c from 20170415 changes.

+ 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

+
+20170422
+ + 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.
+
+20170415
+ + modify several test programs to use new popup_msgs, adapted from

+ + 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(),

+ + add new functions for manipulating color- and pair-values larger
+ than 16-bits. These are extended_color_content(),

+ init_extended_pair(), and the corresponding sp-funcs.
+
+20170325
+ + 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.
+
+20170318
+ + 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

+
+20170218
+ + 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 "@, -".
+

+ similar options for the other libraries.
+
+20170204
+ + 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.

+ + 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.
+
+20170114
+ + 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.
+
+20170107
+ + 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

+
+20161231

+ + 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

+ 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

+ + 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,

+ did not work after changes in 20130112.
+
+20161210
+ + 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.
+
+20161203
+ + improve discussion of field validation in form_driver.3x manual page.
+ + update curs_trace.3x manual page.
+
+20161126
+ + modify linux-16color to not mask dim, standout or reverse with the

+ + 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).
+
+20161119

+
+20161029
+ + add new function "unfocus_current_field" (Leon Winter)
+
+20161022
+ + modify tset -w (and tput reset) to update the program's copy of the
+ screensize if it was already set in the system, to improve tabstop
+ setting which relies upon knowing the actual screensize.
+ + add functionality of tset -w to tput, like the "-c" feature this is
+ not optional in tput.
+ + add "clear" as a possible link/alias to tput.
+ + improve tput's check for being called as "init" or "reset" to allow
+ for transformed names.
+ + split-out the "clear" function from progs/clear.c, share with
+ tput to get the same behavior, e.g., the E3 extension.
+
+20161015
+ + amend internal use of tputs to consistently use the number of lines
+ affected, e.g., for insert/delete character operations. While
+ merging terminfo source early in 1995, several descriptions used the
+ "*" proportional delay for these operations, prompting a change in
+ doupdate.
+ + regenerate llib-* files.
+ + regenerate HTML manpages.
+ + fix several formatting issues with manual pages.
+
+20161008
+ + adjust size in infocmp/tic to work with strlcpy.
+ + fix configure script to record when strlcat is found on OpenBSD.
+ + build-fix for "recent" OpenBSD vs baudrate.
+
+20161001
+ + add -W option to tic/infocmp to force long strings to wrap. This is

+ + correct rs2 string for vt100-nam -TD
+
+20160924

+ + updated minitel and viewdata descriptions (Alexandre Montaron).
+
+20160917
+ + build-fix for gnat6, which unhelpfully attempts to compile C files.
+ + fix typo in 20160910 changes (Debian #837892, patch by Sven Joachim).
+
+20160910
+ + trim dead code ifdef'd with HIDE_EINTR since 970830 (discussion with

+ "bsd" library and its associated "<bsd/string.h>" header.
+
+20160903
+ + correct 20100515 change for weak signals versus sigprocmask (report
+ by Rich Coe).
+ + modify misc/Makefile.in to work around OpenBSD "make" which unlike
+ all other versions of "make" does not recognize continuation lines
+ of comments.
+ + amend the last change to CF_C_ENV_FLAGS to move only the
+ preprocessor, optimization and warning flags to CPPFLAGS and CFLAGS,
+ leaving the residue in CC. That happens to work for gcc's various
+ "model" options, but may require tuning for other compilers (report
+ by Sven Joachim).
+
+20160827
+ + add "v" menu entry to test/ncurses.c to show baudrate and other

+ + modify _GNU_SOURCE for cygwin headers, tested with cygwin 2.3, 2.5
+ (patch by Corinna Vinschen, from changes to tin).
+ + improve CF_CC_ENV_FLAGS macro to allow for compiler wrappers such
+ as "ccache" (report by Enrico Scholz).
+ + update config.guess, config.sub from
+ http://git.savannah.gnu.org/cgit/config.git
+
+20160820
+ + update tput manual page to reflect changes to manipulate terminal
+ modes by sharing functions with tset.
+ + add the terminal-mode parts of "reset" (aka tset) to the "tput reset"
+ command, making the two almost the same except for window-size.
+ + adapt logic used in dialog "--keep-tite" option for test/filter.c as
+ "-a" option. When set, test/filter attempts to suppress the
+ alternate screen.
+ + correct a typo in interix entry -TD
+
+20160813
+ + add a dependency upon generated-sources in Ada95/src/Makefile.in to
