190 option, from xterm #363 -TD
191 + modify adjustment in PutCharLR to restore the cursor position before
192 writing to the lower-right corner, rather than decrementing the

1172 + document --with-pcre2 configure option in INSTALL.
1173 + improve workaround for special case in PutAttrChar() where a cell is
1174 marked as alternate-character set, to handle a case where the
1175 character in the cell does not correspond to any of the ASCII
1176 fallbacks (report by Leon Winter, cf: 20180505).
1177 + amend change to form library which attempted to avoid unnecessary
1178 update of cursor position in non-public fields, to simply disable
1179 output in this case (patch by Leon Winter, cf: 20180414).
1180 + improve check for LINE_MAX runtime limit, to accommodate broken
1181 implementations of sysconf().
1184 + improve manual page for wgetnstr, giving background for the length
1186 + define a limit for wgetnstr, wgetn_wstr when length is negative or
1188 + update configure script to autoconf 2.52.20180819 (Debian #887390).
1191 + add a section to tput manual page clarifying how it determines the
1192 terminal size (prompted by discussion with Grant Jenks).
1193 + add "--disable-relink" to rpm test-packages, for consistency with the
1195 + split spec-file into ncurses6.spec and ncursest6.spec to work around
1196 toolset breakage in Fedora 28.
1197 + drop mention of "--disable-touching", which was not in the final
1201 + build-fix for PDCurses with ncurses-examples.
1202 + improved CF_CC_ENV_FLAGS.
1203 + modify configure scripts to reduce relinking/ranlib during library
1204 install (Debian #903790):
1205 + use "install -p" when available, to avoid need for ranlib of
1207 + modify scripts which use "--disable-relink" to add a 1-second
1208 sleep to work around tools which use whole-second timestamps, e.g.,
1209 in utime() rather than the actual file system resolution.
1212 + improve logic for clear with E3 extension, in case the terminal
1213 scrolls content onto its saved-lines before actually clearing
1214 the display, by clearing the saved-lines after clearing the
1215 display (report/patch by Nicholas Marriott).

1243 (Nicholas Marriott).
1244 + minor fixes prompted by anonymous report on stack overflow:
1245 + correct order of checks in _nc_get_locale(), for systems lacking
1247 + add "#error" in a few places to flag unsupported configurations
1250 + use _WIN32/_WIN64 in preference to __MINGW32__/__MINGW64__ symbols
1251 to simplify building with MSVC, since the former are defined in both
1252 compiler configurations (report by Ali Abdulkadir).
1253 + further improvements to configure-checks from work on dialog, i.e.,
1254 updated CF_ADD_INCDIR, CF_FIND_LINKAGE, CF_GCC_WARNINGS,

1286 + fix some gcc8 warnings seen in Redhat package build, but
1287 work around bug in gcc8 compiler warnings in comp_parse.c
1290 + formatting fixes for manpages, regenerate man-html documentation.
1291 + trim spurious whitespace from tmux in 2018-02-24 changes;
1292 fix some inconsistencies in/between tmux- and iterm2-entries for SGR
1293 (report by C Anthony Risinger)
1294 + improve iterm2 using some xterm features which it has adapted -TD
1295 + add check in pair_content() to handle the case where caller asks
1296 for an uninitialized pair (Debian #898658).
1299 + remove trailing ';' from GCC_DEPRECATED definition.
1300 + repair a change from 20110730 which left an error-check/warning dead.
1301 + fix several minor Coverity warnings.
1304 + add deprecation warnings for internal functions called by older
1306 + fix a special case in PutAttrChar() where a cell is marked as
1307 alternate-character set, but the terminal does not actually support
1308 the given graphic character. This would happen in an older terminal
1309 such as vt52, which lacks most line-drawing capability.
1310 + use configure --with-config-suffix option to work around filename
1311 conflict with Debian packages versus test-packages.
1312 + update tracemunch to work with perl 5.26.2, which changed the rules

1331 + also add/improve null-pointer checks in other places
1332 + add a null-pointer check in _nc_parse_entry to handle an error when
1333 a use-name is invalid syntax (report by Chung-Yi Lin).
1336 + clarify in manual pages that vwprintw and vwscanw are obsolete,
1337 not part of X/Open Curses since 2007.
1338 + use "const" in some prototypes rather than NCURSES_CONST where X/Open
1339 Curses was updated to do this, e.g., wscanw, newterm, the terminfo
1340 interface. Also use "const" for consistency in the termcap
1341 interface, which was withdrawn by X/Open Curses in Issue 5 (2007).
1342 As of Issue 7, X/Open Curses still lacks "const" for certain return
1343 values, e.g., keyname().
1346 + improve terminfo write/read by modifying the fourth item of the
1347 extended header to denote the number of valid strings in the extended
1348 string table (prompted by a comment in unibilium's sources).
1351 + amend Scaled256() macro in test/picsmap.c to cover the full range
1352 0..1000 (report by Roger Pau Monne).

1361 different strings, but provide identical results to setaf/setab.
1362 + further improve fix for terminfo.5 (patch by Kir Kolyshkin).
1363 + reorder loop-limit checks in winsnstr() in case the string has no
1364 terminating null and only the number of characters is used (patch
1368 + modify TurnOn/TurnOff macros in lib_vidattr.c and lib_vid_attr.c to
1369 avoid expansion of "CUR" in trace.
1370 + improve a few lintian warnings in test-packages.
1371 + modify lib_setup to avoid calling pthread_self() without first
1372 verifying that the address is valid, i.e., for weak symbols
1373 (report/patch by Werner Fink).
1374 + modify generated terminfo.5 to not use "expand" and related width
1375 on the last column of tables, making layout on wide terminals look
1376 better (adapted from patch by Kir Kolyshkin).
1377 + add a category to report_offsets, e.g., "w" for wide-character, "t"
1378 for threads to make the report more readable. Reorganized the
1379 structures reported to make the categories more apparent.
1380 + simplify some ifdef's for extended-colors.
1381 + add NCURSES_GLOBALS and NCURSES_PRESCREEN to report_offsets, to show
1382 how similar the different tinfo configurations are.
1385 + modify _nc_resolve_uses2() to detect incompatible types when merging
1386 a "use=" clause of extended capabilities. The problem was seen in a
1387 defective terminfo integrated from simpleterm sources in 20171111,
1388 compounded by repair in 20180121.
1389 + correct Ss/Ms interchange in st-0.7 entry (tmux #1264) -TD
1390 + fix remaining flash capabilities with trailing mandatory delays -TD
1391 + correct cut/paste in NEWS (report by Sven Joachim).
1394 + remove incorrect free() from 20170617 changes (report by David Macek).
1395 + correct type for "U8" in user_caps.5; it is a number not boolean.
1396 + add a null-pointer check in safe_sprintf.c (report by Steven Noonan).
1397 + improve fix for Debian #882620 by reusing limit2 variable (report by
1398 Julien Cristau, Sven Joachim).
1401 + modify misc/Makefile.in to install/uninstall explicit list in case
1402 the build-directory happens to have no ".pc" files when an uninstall
1403 is performed (report by Jeffrey Walton).
1404 + deprecate safe-sprintf, since the vsnprintf function, which does what
1405 was needed, was standardized long ago.
1406 + add several development/experimental options to development packages.
1407 + minor reordering of options in configure script to make the threaded
1408 and reentrant options distinct from the other extensions which are
1412 + minor fixes to test/*.h to make them idempotent.
1413 + add/use test/parse_rgb.h to show how the "RGB" capability works.

1468 > merge branch begun April 2, 2017 which provides these features:
1469 + support read/write new binary-format for terminfo which stores
1470 numeric capabilities as a signed 32-bit integer. The test programs
1471 such as picsmap, ncurses were created or updated during 2017 to use
1473 + the new format is written by the wide-character configuration of
1474 tic when it finds a numeric capability larger than 32767.
1475 + other applications such as infocmp built with the wide-character
1476 ncurses library work as expected.
1477 + applications built with the "narrow" (8-bit) configuration will
1478 read the new format, but will limit those extended values to 32767.
1479 + in either wide/narrow configuration, the structure defined in
1480 term.h still uses signed 16-bit values.
1481 + because it is incompatible with the legacy (mid-1980s) binary format,
1482 a new magic value is provided for the "file" program.
1483 + the term.5 manual page is updated to describe this new format.
1484 + the limit on file-size for compiled terminfo is increased in the
1485 wide-character configuration to 32768.
1488 + build-fix in picsmap.c for stdint.h existence.
1489 + add --disable-stripping option to configure scripts.
1490 + modify ncurses-examples to install test-scripts in the data directory.
1491 + work around tool-breakage in Debian 9 and later by invoking
1492 gprconfig to specify the C compiler to be used by gnatmake,
1493 and conditionally suppressing Library_Options line for static
1495 + bump the compat level for test-packages to 7, i.e., Debian 5.
1498 + fixes for writing extended color pairs in putwin.
1499 + modify test/savescreen.c to add test patterns that exercise 88-,
1501 + modify configure option --with-build-cc, adding clang, c89 and c99
1502 as possible default values.
1503 + modify ncurses-examples configure script to use pkg-config for the
1504 extra form/menu/panel libraries, to be more consistent with the
1505 handling of the curses/ncurses library.
1506 + modify test-packages for mingw to supply "pc" files.
1507 + modify gen-pkgconfig.in to list -lpthread as a private library when
1508 configured to access it via weak symbols.
1509 + simplify gen-pkgconfig.in, adding -ltinfo without the special linker
1510 checks because some versions of the linker simply hard-code the
1512 + update URLs for ncurses website to use https.
1513 + modify CF_CURSES_LIBS to fill in $cf_nculib_root in case the
1514 ncurses-examples are built with a system ncurses that lacks the
1515 standard "curses" symbolic link, as done by SuSE. The symbol is
1516 needed to make a followup check for the pthread library work, and
1517 would be set properly using the options "--with-screen", etc.
1518 + generate misc/*.pc with "all" rule, as done for "sources" rule
1519 (report by Jeffrey Walton).
1522 + build-fix for ncurses-examples with Fedora27, adding check for
1523 reset_color_pairs() -- not yet in Fedora's package.
1524 + consistently add $CFLAGS to $MK_SHARED_LIB symbol in configure
1525 script when the latter happens to use the C compiler rather than
1526 directly using the loader (report by Jeffrey Walton).
1527 + set ABI for upcoming 6.1 release in "*.map" files. While there are
1528 some remaining internals to apply, no ABI-related changes are
1530 + add configure --with-config-suffix option to work around filename
1531 conflict with Redhat packages versus test-packages.
1534 + modify ncurses-examples to quiet const-warnings when building with
1536 + modify toe to not exit if unable to read a terminal description,
1537 e.g., if there is a permission problem.
1538 + minor fix for progs/toe.c, using _nc_free_termtype2.
1539 + assign 0 to pointer in _nc_tgetent_leak() after freeing it. Also
1540 avoid reusing pointer from previous successful call to tgetent
1541 if the latest call is unsuccessful (patch by Michael Schroeder,
1543 + minor fix for test/tracemunch, initialize $awaiting variable.
1546 + repair template in test/package/ncurses-examples.spec (cf: 20171111).
1547 + improve tic's warning about the number of parameters tparm might use
1548 for u1-u9 by making a special case for u6.
1549 + improve curs_attr.3x discussion of color pairs.
1552 + modify misc/ncurses-config.in to make output with --includedir
1553 consistent with --cflags, i.e., when --disable-overwrite option was
1554 configured the output should show the subdirectory where headers
1556 + modify MKlib_gen.sh to suppress macros when calling an "implemented"
1557 function in link_test.c
1558 + updated ftp-url used in test-packages, etc.
1559 + modify order of -pie/-shared options in configure script in case
1560 LDFLAGS uses "-pie", working around a defect or limitation in the GNU
1561 linker (prompted by patch by Yogesh Prasad, forwarded by Jay Shah).
1562 + add entry in man_db.renames for user_caps.5
1565 + modify MKlib_gen.sh to avoid tracing result from getstr/getnstr
1567 + add "-a" aspect-ratio option to picsmap.
1568 + add configure check for default path of rgb.txt, used in picsmap.
1569 + modify _nc_write_entry() to truncate too-long filename (report by
1570 Hosein Askari, Debian #882620).
1571 + build-fix for ncurses-examples with NetBSD curses:
1572 + it lacks the use_env() function.
1573 + it lacks libpanel; a recent change used the wrong ifdef symbol.
1574 + add a macro for is_linetouched() and adjust the function's return
1575 value to make it possible for most applications to check for an
1576 error-return (report by Midolikawa H).
1577 + additional manpage cleanup.
1578 + update config.guess, config.sub from
1579 http://git.savannah.gnu.org/cgit/config.git
1582 + add a note to curs_addch.3x on portability.

1584 + improve manpage description of getattrs (report by Midolikawa H).
1585 + improve manpage macros (prompted by discussion in Debian #880551.
1586 + reviewed test-programs using KEY_RESIZE, made fixes to test/worm.c
1587 + add a "-d" option to picsmap for default-colors.
1588 + modify old terminology entry and a few other terminal emulators to
1590 + correct sgr string for tmux, which used screen's "standout" code
1591 rather than the standard code (patch by Roman Kagan)
1592 + correct sgr/sgr0 strings in a few other cases reported by tic, making
1593 those correspond to the non-sgr settings where they differ, but
1594 otherwise use ECMA-48 consistently:
1595 jaixterm, aixterm, att5420_2, att4424, att500, decansi, d410-7b,
1596 dm80, hpterm, emu-220, hp2, iTerm2.app, mterm-ansi, ncrvt100an,
1597 st-0.7, vi603, vwmterm -TD

1622 available; add a "S" wide-character overlap test-screen.
1623 + modify test/ncurses.c C/c tests to allow for extended color pairs.
1624 + add endwin() call in error-returns from test/ncurses.c omitted in
1625 recent redesign of its menu (cf: 20170923).
1626 + improve install of hashed-db by removing the ".db" file as done for
1627 directory-tree terminal databases.
1628 + repair a few overlooked items in include/ncurses_defs from recent
1629 port/refactoring of test-programs (cf: 20170909).
1630 + add test/padview.c, to compare pads with direct updates in view.c
1633 + modify test/view.c to expand tabs using the ncurses library rather
1634 than in the test-program.
1635 + remove very old SIGWINCH example in test/view.c, just use KEY_RESIZE.
1636 + add -T, -e, -f -m options to "dots" test-programs.

1649 + modify demo_new_pair.c to pass extended pairs to setcchar().
1650 + add test/dots_xcurses.c to illustrate a different approach used for
1651 extended colors which can be contrasted with dots_curses.c.
1652 + add a check in tic to note when a description uses non-mandatory
1653 delays without xon_xoff. This is not an error, but some descriptions
1654 for a terminal emulator may use the combination incorrectly.
1657 + modify "-T" option of clear and tput to call use_tioctl() to obtain
1658 the operating system's notion of the screensize if possible.
1659 + review/repair some exit-codes for tput, making usage-message exit
1660 with 2 rather than 1, and a failure to open terminal 4+errno.

1666 + regenerate man-html documentation.
1669 + fix a symbol conflict that made ncurses.c C/c menu not work with
1670 Solaris xpg4 curses.
1671 + add refresh() call to dots_mvcur.c, needed to use mvcur() with
1672 Solaris xpg4 curses after calling newterm().
1673 + minor fixes for configure script from work on ncurses-examples and
1675 + improve animation in test/xmas.c by adding a time-delay in blinkit().
1676 + modify several test programs to reflect that ncurses honors existing
1677 signal handlers in initscr(), while other implementations do not.
1678 + modify bs.c to make it easier to quit.
1679 + change ncurses-examples to use attr_t vs chtype to follow X/Open
1680 documentation more closely since Solaris xpg4-curses uses different
1681 values for WA_xxx vs A_xxx that rely on attr_t being an unsigned
1682 short. Tru64 aka OSF1, HPUX, AIX did as ncurses does, equating the
1686 + modify menu for test/ncurses.c to fit on 24-line screen.
1687 + build-fix for configure --with-caps=uwin
1688 + add options to test_arrays.c, for selecting termcap vs terminfo, etc.
1691 + minor fix to test/filter.c to avoid clearing the command in one case.
1692 + modify filter() to discard clr_eos if back_color_erase is set.
1695 + improve wide-character implementation of myADDNSTR() in frm_driver.c,
1696 which was inconsistent with the normal implementation.
1697 + save/restore cursor position in Undo_Justification(), matching
1698 behavior of Buffer_To_Window() (report by Leon Winter).
1699 + modify test/knight to provide the "slow" solution for small screens
1700 using "R", noting that Warnsdorf's method is easily done with "a".
1701 + modify several test-programs which call use_default_colors() to
1702 consistently do this only if "-d" option is given.
1703 + additional changes to test with non-standard variants of curses:
1704 + modify a loop limit in firework.c to work around absence of limit
1705 checks in some libraries.
1706 + fill the last row of a window with "?" in firstlast if waddch does
1707 not return ERR on the lower-right corner.
1708 + add checks in test/configure for some functions not in 4.3BSD curses.
1709 + fix a regression in test/configure (cf: 20170826).
1712 + amend change for endwin-state for better consistency with the older
1713 logic (report/patch by Jeb Rosen, cf: 20170722).
1714 + modify check in fmt_entry() to handle a cancelled reset string
1715 (Debian #873746). Make similar fixes in other parts of dump_entry.c
1719 + fix a bug in repeat_char logic (cf: 20170729, report by Chris Clayton).
1722 + fixes for "iterm2" (report by Leonardo Brondani Schenkel) -TD
1723 + corrected a warning from tic about keys which are the same, to skip
1724 over missing/cancelled values.
1725 + add check in tic for unnecessary use of "2" to denote a shifted
1727 + improve checks in trim_sgr0, comp_parse.c and parse_entry.c, for
1728 cancelled string capabilities.
1729 + add check in _nc_parse_entry() for invalid entry name, setting the
1730 name to "invalid" to avoid problems storing entries.
1731 + add/improve checks in tic's parser to address invalid input
1732 + add a check in comp_scan.c to handle the special case where a
1733 nontext file ending with a NUL rather than newline is given to tic
1734 as input (Redhat #1484274).
1735 + allow for cancelled capabilities in _nc_save_str (Redhat #1484276).
1736 + add validity checks for "use=" target in _nc_parse_entry (Redhat
1738 + check for invalid strings in postprocess_termcap (Redhat #1484285)
1739 + reset secondary pointers on EOF in next_char() (Redhat #1484287).
1740 + guard _nc_safe_strcpy() and _nc_safe_strcat() against calls using
1741 cancelled strings (Redhat #1484291).
1742 + correct typo in curs_memleaks.3x (Sven Joachim).
1743 + improve test/configure checks for some curses variants not based on
1745 + add options for test/configure to disable checks for form, menu and
1749 + update "iterm" entry -TD
1750 + add "iterm2" entry (report by Leonardo Brondani Schenkel) -TD
1751 + regenerate llib-* files.
1752 + regenerate HTML manpages.
1753 + improve picsmap test-program:
1754 + reduce memory used for tsearch
1755 + add report in log file showing cumulative color coverage.
1756 + add -x option to clear/tput to make the E3 extension optional
1758 + add options -T and -V to clear command for compatibility with tput.
1759 + add usage message to clear command (Debian #371855).
1760 + improve usage messages for tset and tput.
1761 + minor fixes to "RGB" extension and reset_color_pairs().
1764 + improve description of -R option in infocmp manual page (report by
1766 + add reset_color_pairs() function.
1767 + add user_caps.5 manual page to document the terminfo extensions used
1769 + improve build scripts, using SIGQUIT vs SIGTRAP; add other configure
1770 script fixes from work on xterm, lynx and tack.
1771 + modify install-rule for ncurses-examples to put the data files in
1772 /usr/share/ncurses-examples
1773 + improve tracemunch, by changing address-parameters of add_wch(),
1774 color_content() and pair_content() to dummy parameters.
1775 + minor optimization to _nc_change_pair, to return quickly when the
1776 current screen is marked for clearing.
1777 + in-progress changes to improve performance of test/picsmap.c for
1778 loading image files.
1779 + modify allocation for SCREEN's color-pair table to start small, grow
1780 on demand up to the existing limit.
1781 + add "RGB" extension capability for direct-color support, use this to
1782 improve color_content().
1783 + improve picsmap test-program:
1784 + if no palette file is needed, attempt to load one based on $TERM,
1785 checking first in the current directory, then by adding ".dat"
1786 suffix, and finally in the data-directory, e.g.,
1787 /usr/share/ncurses-examples
1788 + add "-l" option for logging
1789 + add "-d" option for debugging
1790 + add "-s" option for stepping automatically through list of images,
1792 + use tsearch to improve time for loading color table for images.
1793 + update config.guess, config.sub from
1794 http://git.savannah.gnu.org/cgit/config.git
1797 + update interix entry using tack and SFU on Windows 7 Ultimate -TD
1798 + use ^? for kdch1 in interix (reported by Jonathan de Boyne Pollard)
1799 + add "rep" to xterm-new, available since 1997/01/26 -TD
1800 + move SGR 24 and 27 from vte-2014 to vte-2012 (request by Alain
1802 + add a check in newline_forces_scroll() in case a program moves the
1803 cursor outside scrolling margins (report by Robert King).
1804 + improve _nc_tparm_analyze, using that to extend the checks made by
1805 tic for reporting inconsistencies between the expected number of
1806 parameters for a capability and the actual.
1807 + amend handling of repeat_char capability in EmitRange (adapted from
1808 report/patch by Dick Wesseling):
1809 + translate the character to the alternate character set when the
1810 alternate character set is enabled.
1811 + do not use repeat_char for characters past 255.
1812 + document "_nc_free_tinfo" in manual page, because it could be used in
1813 tack for memory-leak checking.
1814 + add "--without-tack" configure option to refine "--with-progs"
1815 configure option. Normally tack is no longer built in-tree, but
1816 a few packagers combine it during the build. If term_entry.h is
1817 installed, there is no advantage to in-tree builds.
1818 + adjust configure-script to define HAVE_CURSES_DATA_BOOLNAMES symbol
1819 needed for tack 1.08 when built in-tree. Rather than relying upon
1820 internal "_nc_" functions, tack now uses the boolean, number and
1821 string capability name-arrays provided by ncurses and SVr4 Unix
1822 curses. It still uses term_entry.h for the definitions of the
1823 extended capability arrays.
1824 + add an overlooked null-pointer check in mvcur changes from 20170722
1827 + improve test-packages for ncurses-examples and AdaCurses for lintian
1828 + modify logic for endwin-state to be able to detect the case where
1829 the screen was never initialized, using that to trigger a flush of
1830 ncurses' buffer for mvcur, e.g., in test/dots_mvcur.c for the
1831 term-driver configuration.
1832 + add dependency upon ncurses_cfg.h to a few other internal header
1833 files to allow each to be compiled separately.
1834 + add dependency upon ncurses_cfg.h to tic's header-files; any program
1835 using tic-library will have to supply this file. Legacy tack
1836 versions supply this file; ongoing tack development has dropped the
1837 dependency upon tic-library and new releases will not be affected.
1840 + modify command-line parameters for "convert" used in picsmap to work
1841 with ImageMagick 6.8 and newer.
1842 + fix build-problem with tack and ABI-5 (Debian #868328).
1843 + repair termcap-format from tic/infocmp broken in 20170701 fixes
1845 + reformat terminfo.src with 20170513 updates.
1846 + improve test-packages to address lintian warnings.
1849 + add a note to tic manual page about -W versus -f options.
1850 + correct a limit-check in fixes from 20170701 (report by Sven Joachim).
1853 + modify update_getenv() in db_iterator.c to ensure that environment
1854 variables which are not initially set will be checked later if an
1855 application happens to set them (patch by Guillaume Maudoux).
1856 + remove initialization-check for calling napms() in the term-driver
1857 configuration; none is needed.
1858 + add help-screen to test/test_getstr.c and test/test_get_wstr.c
1859 + improve compatibility between different configurations of new_prescr,
1860 fixing a case with threaded code and term-driver where c++/demo did
1861 not work (cf: 20160213).
1862 + the fixes for Redhat #1464685 obscured a problem subsequently
1863 reported in Redhat #1464687; the given test-case was no longer
1864 reproducible. Testing without the fixes for the earlier reports
1865 showed a problem with buffer overflow in dump_entry.c, which is
1866 addressed by reducing the use of a fixed-size buffer.
1867 + add/improve checks in tic's parser to address invalid input
1868 (Redhat #1464684, #1464685, #1464686, #1464691).
1869 + alloc_entry.c, add a check for a null-pointer.
1870 + parse_entry.c, add several checks for valid pointers as well as
1871 one check to ensure that a single character on a line is not
1872 treated as the 2-character termcap short-name.
1873 + fix a memory leak in delscreen() (report by Bai Junq).
1874 + improve tracemunch, showing thread identifiers as names.
1875 + fix a use-after-free in NCursesMenu::~NCursesMenu()
1876 + further amend incorrect calls for memory-leaks from 20170617 changes
1877 (report by Allen Hewes).
1880 + modify c++/etip.h.in to accommodate deprecation of throw() and
1881 throws() in c++17 (prompted by patch by Romain Geissler).
1882 + remove some incorrect calls for memory-leaks from 20170617 changes
1883 (report by Allen Hewes).
1884 + add test-programs for termattrs and term_attrs.
1885 + modify _nc_outc_wrapper to use the standard output if the screen was
1886 not initialized, rather than returning an error.
1887 + improve checks for low-level terminfo functions when the terminal
1888 has not been initialized (Redhat #1345963).
1889 + modify make_hash to allow building with address-sanitizer,
1890 assuming that --disable-leaks is configured.
1891 + amend changes for number_format() in 20170506 to avoid undefined
1892 behavior when shifting (patch by Emanuele Giaquinta).
1895 + fill in some places where TERMTYPE2 vs TERMTYPE was not used
1896 (report by Allen Hewes).
1897 + use ExitTerminfo() internally in error-exits for ncurses' setupterm
1898 to help with leak checking.
1899 + use ExitProgram() in error-exit from initscr() to help with leak
1901 + review test-programs, adding checks for cases where the terminal
1902 cannot be initialized.
1905 + add option "-xp" to picsmap.c, to use init_extended_pair().
1906 + make simple performance fixes for picsmap.c
1907 + improve aspect ratio of images read from "convert" in picsmap.c
1910 + add option to picsmap to use color-palette files, e.g., for mapping
1912 + move the data in SCREEN used for the alloc_pair() function to the
1913 end, to restore compatibility between ncurses/ncursesw libtinfo
1914 (report/patch by Miroslav Lichvar).
1915 + add build-time utility "report_offsets" to help show when the various
1916 configurations of tinfo library are compatible or not.
1919 + improved test/picsmap.c:
1920 + lookup named colors for xpm files in rgb.txt
1921 + accept blanks in color-keys for xpm files.
1922 + if neither xbm/xpm work, try "convert", which may be available.
1925 + modify test/picsmap.c to read xpm files.
1926 + modify package/debian/* to create documentation packages, so the
1927 related files can be checked with lintian.
1928 + fix some typos in manpages (report/patch by Sven Joachim).
1931 + add test/picsmap.c to fill in some testing issues not met by dots.
1932 The initial version reads X bitmap (".xbm") files.
1933 + repair logic which forces a repaint where a color-pair's content is
1934 changed (cf: 20170311).
1935 + improve tracemunch, showing screenXX pointers as names.
1938 + modify tic/infocmp display of numeric values to use hexadecimal when
1939 they are "close" to a power of two, making the result more readable.
1940 + improve discussion of portability in curs_mouse.3x
1941 + change line-length for generated html/manpages to 78 columns from 65.
1942 + improve discussion of line-drawing characters in curs_add_wch.3x
1943 (prompted by discussion with Lorinczy Zsigmond).
1944 + cleanup formatting of hackguide.html and ncurses-intro.html
1945 + add examples for WACS_D_PLUS and WACS_T_PLUS to test/ncurses.c
1948 + corrected a case where $with_gpm was set to "maybe" after CF_WITH_GPM,
1949 overlooked in 20160528 fixes (report by Alexandre Bury).
1950 + improve a couple of test-program's help-messages.
1951 + corrected loop in rain.c from 20170415 changes.
1952 + modify winnstr and winchnstr to return error if the output pointer is
1953 null, as well as adding a null pointer check of the window pointer
1954 for better compatibility with other implementations.
1955 + improve discussion of NetBSD curses in scr_dump.5
1956 + modify LIMIT_TYPED macro in new_pair.h to avoid changing sign of the
1957 value to be limited (reports by Darby Payne, Rob Boudreau).
1958 + update config.guess, config.sub from
1959 http://git.savannah.gnu.org/cgit/config.git
1962 + build-fix for termcap-configuration (report by Chi-Hsuan Yen).
1963 + improve terminfo manual page discussion of control- and graphics-
1965 + remove tic warning about "^?" in string capabilities, which was
1966 marked as an extension (cf: 20000610, 20110820); however all Unix
1967 implementations support this and X/Open Curses does not address it.
1968 On the other hand, termcap never did support this feature.
1969 + correct missing comma-separator between string capabilities in
1970 icl6402 and m2-nam -TD
1971 + restore rmir/smir in ansi+idc to better match original ansiterm+idc,
1972 add alias ansiterm (report by Robert King).
1973 + amend an old check for ambiguous use of "ma" in terminfo versus
1974 a termcap use, if the capability is cancelled to treat it as number.
1975 + correct a case in _nc_captoinfo() which read "%%" and emitted "%".
1976 + modify sscanf calls in _nc_infotocap() for patterns "%{number}%+%c"
1977 and "%'char'%+%c" to check that the final character is really 'c',
1978 avoiding a case in icl6404 which cannot be converted to termcap.
1979 + in _nc_infotocap(), add a check to ensure that terminfo "^?" is not
1980 written to termcap, because the BSDs did not implement that.
1981 + in _nc_tic_expand() and _nc_infotocap(), improve string-length check
1982 when deciding whether to use "^X" or "\xxx" format for control
1983 characters, to make the output of tic/infocmp more predictable.
1984 + limit termcap "%d" width to 2 digits on input, and use "%2" in
1985 preference to "%02" on output.
1986 + correct terminfo/termcap conversion of "%02" and "%03" into "%2" and
1987 "%3"; the result repeated the last character.
1988 + add man/scr_dump.5 to document screen-dump format.
1991 + modify several test programs to use new popup_msgs, adapted from
1992 help-screen used in test/edit_field.c
1993 + drop two symbols obsoleted in 2004: _nc_check_termtype, and
1995 + fix some old copyright dates (cf: 20031025).
1996 + build-fixes for test/savescreen.c to work with AIX and HPUX.
1997 + minor fix to configure script, adding a backslash/continuation.
1998 + extend TERMINAL structure for ABI 6 to store numbers internally as
1999 integers rather than short, by adding new data for this purpose.
2000 + more fixes for minor memory-leaks in test-programs.
2003 + change logic in wins_nwstr() to avoid addressing data past the output
2005 + correct a call to setcchar() in Data_Entry_w() from 20131207 changes.
2006 + fix minor memory-leaks in test-programs.
2007 + further improve ifdef in term_entry.h for internal definitions not
2011 + minor fixes for vt100+4bsd, e.g., delay in sgr for consistency -TD
2012 + add smso for env230, to match sgr -TD
2013 + remove p7/protect from sgr in fbterm -TD
2014 + drop setf/setb from fbterm; setaf/setab are enough -TD
2015 + make xterm-pcolor sgr consistent with other capabilities -TD
2016 + add rmxx/smxx ECMA-48 strikeout extension to tmux and xterm-basic
2017 (discussion with Nicholas Marriott)
2018 + add test-programs sp_tinfo and extended_color
2019 + modify no-leaks code for lib_cur_term.c to account for the tgetent()
2021 + modify setupterm() to save original tty-modes so that erasechar()
2022 works as expected. Also modify _nc_setupscreen() to avoid redundant
2023 calls to get original tty-modes.
2024 + modify set_curterm() to update ttytype[] data used by longname().
2025 + modify wattr_set() and wattr_get() to return ERR if win-parameter is
2026 null, as documented.
2027 + improve cast used for null-pointer checks in header macros, to
2028 reduce compiler warnings.
2029 + modify several functions, using the reserved "opts" parameter to pass
2030 color- and pair-values larger than 16-bits:
2031 + getcchar(), setcchar(), slk_attr_set(), vid_puts(), wattr_get(),
2032 wattr_set(), wchgat(), wcolor_set().
2033 + Other functions call these with the corresponding altered behavior,
2034 including chgat(), mvchgat(), mvwchgat(), slk_color_on(),
2035 slk_color_off(), vid_attr().
2036 + add new functions for manipulating color- and pair-values larger
2037 than 16-bits. These are extended_color_content(),
2038 extended_pair_content(), extended_slk_color(), init_extended_color(),
2039 init_extended_pair(), and the corresponding sp-funcs.
2042 + fix a memory leak in the window-list when creating multiple screens
2043 (reports by Andres Martinelli, Debian #783486).
2044 + reviewed calls from link_test.c, added a few more null-pointer
2046 + add a null-pointer check in ungetmouse, in case mousemask was not
2047 called (report by "Kau").
2048 + updated curs_sp_funcs.3x for new functions.
2051 + change TERMINAL structure in term.h to make it opaque. Some
2052 applications misuse its members, e.g., directly modifying it
2053 rather than using def_prog_mode().
2054 + modify utility headers such as tic.h to make it clearer which are
2055 externals that are used by tack.
2056 + improve curs_slk.3x in particular its discussion of portability.
2057 + fix cut/paste in legacy_encoding.3x
2058 + add prototype for find_pair() to new_pair.3x (report by Branden
2060 + fix a couple of broken links in generated man-html documentation.
2061 + regenerate man-html documentation.
2064 + modify vt100 rs2 string to reset vt52 mode and scrolling regions
2065 (report/analysis by Robert King) -TD
2066 + add vt100+4bsd building block, use that for older terminals rather
2067 than "vt100" which is now mostly used as a building block for
2068 terminal emulators -TD
2069 + correct a few spelling errors in terminfo.src comments -TD
2071 + fix a typo in ncurses.c test_attr legend (patch by Petr Vanek).
2072 + changed internal colorpair_t to a struct, eliminating an internal
2073 8-bit limit on colors
2074 + add ncurses/new_pair.h

2076 free_pair() functions
2077 + add test/demo_new_pair.c
2080 + improve terminfo manual description of terminfo syntax.
2081 + clarify the use of wint_t vs wchar_t in curs_get_wstr.3x
2082 + improve description of endwin() in manual.
2083 + modify setcchar() and getcchar() to treat negative color-pair as an
2085 + fix a typo in include/hashed_db.h (Andre Sa).
2088 + fixes for CF_CC_ENV_FLAGS (report by Ross Burton).
2091 + fix several formatting issues with manual pages.
2092 + correct read of terminfo entry in which all strings are absent or
2093 explicitly cancelled. Before this fix, the result was that all were
2094 treated as only absent.
2095 + modify infocmp to suppress mixture of absent/cancelled capabilities
2096 that would only show as "NULL, NULL", unless the -q option is used,
2097 e.g., to show "-, @" or "@, -".
2100 + build-fixes for PGI compilers (report by Adam J. Stewart)
2101 + accept whitespace in sed expression for generating expanded.c
2102 + modify configure check that g++ compiler warnings are not used.
2103 + add configure check for -fPIC option needed for shared libraries.
2104 + let configure --disable-ext-funcs override the default for the
2105 --enable-sp-funcs option.
2106 + mark some structs in form/menu/panel libraries as potentially opaque
2107 without modifying API/ABI.
2108 + add configure option --enable-opaque-curses for ncurses library and
2109 similar options for the other libraries.
2112 + trim newlines, tabs and escaped newlines from terminfo "paths" passed
2114 + ignore zero-length files in db-iterator; these are useful for
2115 instance to suppress "$HOME/.terminfo" when not wanted.
2116 + amended "b64:" encoder to work with the terminfo reader.
2117 + modify terminfo reader to accept "b64:" format using RFC-3548 in
2118 as well as RFC-4648 url/filename-safe format.
2119 + modify terminfo reader to accept "hex:" format as generated by
2120 "infocmp -0qQ1" (cf: 20150905).
2121 + adjust authors comment to reflect drop below 1% for SV.
2124 + minor comment-fixes to help automate links to bug-urls -TD
2125 + add dvtm, dvtm-256color -TD
2126 + add settings corresponding to xterm-keys option to tmux entry to
2127 reflect upcoming change to make that option "on" by default
2128 (patch by Nicholas Marriott).
2129 + uncancel Ms in tmux entry (Harry Gindi, Nicholas Marriott).
2130 + add dumb-emacs-ansi -TD
2133 + improve discussion of early history of tput program.
2134 + incorporate A_COLOR mask into COLOR_PAIR(), in case user application
2135 provides an out-of-range pair number (report by Elijah Stone).
2136 + clarify description in tput manual page regarding support for
2137 termcap names (prompted by FreeBSD #214709).
2138 + remove a restriction in tput's support for termcap names which
2139 omitted capabilities normally not shown in termcap translations
2141 + modify configure script for clang as used on FreeBSD, to work around
2142 clang's differences in exit codes vs gcc.
2145 + improve discussion of early history of tset/reset programs.
2146 + clarify in manual pages that the optional verbose option level is
2147 available only when ncurses is configured for tracing.
2148 + amend change from 20161231 to avoid writing traces to the standard
2149 error after initializing the trace feature using the environment
2153 + amend changes for tput to reset tty modes to "sane" if the program
2154 is run as "reset", like tset. Likewise, ensure that tset sends
2155 either reset- or init-strings.
2156 + improve manual page descriptions of tput init/reset and tset/reset,
2157 to make it easier to see how they are similar and different.
2158 + move a static result from key_name() to _nc_globals
2159 + modify _nc_get_screensize to allow for use_env() and use_tioctl()
2160 state to be per-screen when sp-funcs are configured, better matching
2161 the behavior when using the term-driver configuration.
2162 + improve cross-references in manual pages for often used functions
2163 + move SCREEN field for use_tioctl() data before the ncursesw fields,
2164 and limit that to the sp-funcs configuration to improve termlib
2165 compatibility (cf: 20120714).
2166 + correct order of initialization for traces in use_env() and
2167 use_tioctl() versus first trace calls.
2170 + fix errata for ncurses-howto (report by Damien Ruscoe).
2171 + fix a few places in configure/build scripts where DESTDIR and rpath
2172 were combined (report by Thomas Klausner).
2173 + merge current st description (report by Harry Gindi) -TD
2174 + modify flash capability for linux and wyse entries to put the delay
2175 between the reverse/normal escapes rather than after -TD
2176 + modify program tabs to pass the actual tty file descriptor to
2177 setupterm rather than the standard output, making padding work
2179 + explain in clear's manual page that it writes to stdout.
2180 + add special case for verbose debugging traces of command-line
2181 utilities which write to stderr (cf: 20161126).
2182 + remove a trace with literal escapes from skip_DECSCNM(), added in
2184 + update config.guess, config.sub from
2185 http://git.savannah.gnu.org/cgit/config.git

2189 (patch by Leon Winter).
2190 + improve color-handling section in terminfo manual page (prompted by
2191 patch by Mihail Konev).
2192 + modify programs clear, tput and tset to pass the actual tty file
2193 descriptor to setupterm rather than the standard output, making
2197 + add tput-colorcube demo script.
2198 + add -r and -s options to tput-initc demo, to match usage in xterm.
2199 + flush the standard output in _nc_flush for the case where SP is zero,
2200 e.g., when called via putp. This fixes a scenario where "tput flash"
2201 did not work after changes in 20130112.
2204 + add configure script option --disable-wattr-macros for use in cases
2205 where one wants to use the same headers for ncurses5/ncurses6
2206 development, by suppressing the wattr* macros which differ due to
2207 the introduction of extended colors (prompted by comments in
2208 Debian #230990, Redhat #1270534).
2209 + add test/tput-initc to demonstrate tput used to initialize palette
2211 + modify test/xterm*.dat to use the newer color4/color12 values.
2214 + improve discussion of field validation in form_driver.3x manual page.
2215 + update curs_trace.3x manual page.
2218 + modify linux-16color to not mask dim, standout or reverse with the
2220 + add 0.1sec mandatory delay to flash capabilities using the VT100
2221 reverse-video control -TD
2222 + omit selection of ISO-8859-1 for G0 in enacs capability from linux2.6
2223 entry, to avoid conflict with the user-defined mapping. The reset
2224 feature will use ISO-8859-1 in any case (Mikulas Patocka).
2225 + improve check in tic for delays by also warning about beep/flash
2226 when a delay is not embedded, or if those use the VT100 reverse
2227 video escape without using a delay.
2228 + minor fix for syntax-check of delays from 20161119 changes.
2229 + modify trace() to avoid overwriting existing file (report by Maor
2233 + add check in tic for some syntax errors of delays, as well as use of
2234 proportional delays for non-line capabilities.
2235 + document history of the clear program and the E3 extension, prompted
2236 by various discussions including
2237 http://unix.stackexchange.com/questions/87469/clearing-the-old-scrollback-buffer
2240 + improve -W option in tic/infocmp:
2241 + correct order of size-adjustments in wrapped lines
2242 + if -f option splits line, do not further split it with -W
2243 + begin a new line when adding "use=" after a wrapped line
2246 + fix typo in man/terminfo.tail (Alain Williams).
2247 + correct program-name in adacurses6-config.1 manual page.
2250 + add new function "unfocus_current_field" (Leon Winter)
2253 + modify tset -w (and tput reset) to update the program's copy of the
2254 screensize if it was already set in the system, to improve tabstop
2255 setting which relies upon knowing the actual screensize.
2256 + add functionality of tset -w to tput, like the "-c" feature this is
2257 not optional in tput.
2258 + add "clear" as a possible link/alias to tput.
2259 + improve tput's check for being called as "init" or "reset" to allow
2260 for transformed names.
2261 + split-out the "clear" function from progs/clear.c, share with
2262 tput to get the same behavior, e.g., the E3 extension.
2265 + amend internal use of tputs to consistently use the number of lines
2266 affected, e.g., for insert/delete character operations. While
2267 merging terminfo source early in 1995, several descriptions used the
2268 "*" proportional delay for these operations, prompting a change in
2270 + regenerate llib-* files.
2271 + regenerate HTML manpages.
2272 + fix several formatting issues with manual pages.
2275 + adjust size in infocmp/tic to work with strlcpy.
2276 + fix configure script to record when strlcat is found on OpenBSD.
2277 + build-fix for "recent" OpenBSD vs baudrate.
2280 + add -W option to tic/infocmp to force long strings to wrap. This is
2281 in addition to the -w option which attempts to fit capabilities into
2282 a given line-length.
2283 + add linux-m1 minitel entries (patch by Alexandre Montaron).
2284 + correct rs2 string for vt100-nam -TD
2287 + modify _nc_tic_expand to escape comma if it immediately follows a
2288 percent sign, to work with minitel change.
2289 + updated minitel and viewdata descriptions (Alexandre Montaron).
2292 + build-fix for gnat6, which unhelpfully attempts to compile C files.
2293 + fix typo in 20160910 changes (Debian #837892, patch by Sven Joachim).
2296 + trim dead code ifdef'd with HIDE_EINTR since 970830 (discussion with
2298 + trim some obsolete/incorrect wording about EINTR from wgetch manual
2299 page (patch by Leon Winter).
2300 + really correct 20100515 change (patch by Rich Coe).
2301 + add "--enable-string-hacks" option to test/configure
2302 + completed string-hacks for "sprintf", etc., including test-programs.
2303 + make "--enable-string-hacks" work with Debian by checking for the
2304 "bsd" library and its associated "<bsd/string.h>" header.
2307 + correct 20100515 change for weak signals versus sigprocmask (report
2309 + modify misc/Makefile.in to work around OpenBSD "make" which unlike
2310 all other versions of "make" does not recognize continuation lines
2312 + amend the last change to CF_C_ENV_FLAGS to move only the
2313 preprocessor, optimization and warning flags to CPPFLAGS and CFLAGS,
2314 leaving the residue in CC. That happens to work for gcc's various
2315 "model" options, but may require tuning for other compilers (report
2319 + add "v" menu entry to test/ncurses.c to show baudrate and other
2321 + add "newer" baudrate symbols from Linux and FreeBSD to progs/tset.c,
2323 + modify CF_XOPEN_SOURCE macro:
2324 + add "uclinux" to case for "linux" (patch by Yann E. Morin)
2325 + modify _GNU_SOURCE for cygwin headers, tested with cygwin 2.3, 2.5
2326 (patch by Corinna Vinschen, from changes to tin).
2327 + improve CF_CC_ENV_FLAGS macro to allow for compiler wrappers such
2328 as "ccache" (report by Enrico Scholz).
2329 + update config.guess, config.sub from
2330 http://git.savannah.gnu.org/cgit/config.git
2333 + update tput manual page to reflect changes to manipulate terminal
2334 modes by sharing functions with tset.
2335 + add the terminal-mode parts of "reset" (aka tset) to the "tput reset"
2336 command, making the two almost the same except for window-size.
2337 + adapt logic used in dialog "--keep-tite" option for test/filter.c as
2338 "-a" option. When set, test/filter attempts to suppress the
2340 + correct a typo in interix entry -TD
2343 + add a dependency upon generated-sources in Ada95/src/Makefile.in to
2344 handle a case of "configure && make install".
2345 + trim trailing blanks from include/Caps*, to work around a problem
2346 in sed (Debian #818067).
2349 + improve CF_GNU_SOURCE configure macro to optionally define
2350 _DEFAULT_SOURCE work around a nuisance in recent glibc releases.
2351 + move the terminfo-specific parts of tput's "reset" function into
2352 the shared reset_cmd.c, making the two forms of reset use the same
2354 + split-out the terminal initialization functions from tset as
2355 progs/reset_cmd.c, as part of changes to merge the reset-feature
2359 + change tset's initialization to allow it to get settings from the
2360 standard input as well as /dev/tty, to be more effective when
2361 output or error are redirected.
2362 + improve discussion of history and portability for tset/reset/tput
2366 + improve error message from tset/reset when both stderr/stdout are
2367 redirected to a file or pipe.
2368 + improve organization of curs_attr.3x, curs_color.3x
2371 + work around Debian's antique/unmaintained version of mawk when
2373 + improve test/list_keys.c, showing ncurses's convention of modifiers
2374 for special keys, based on xterm.
2377 + improve test/list_keys.c, using $TERM if no parameters are given.
2380 + build-fixes for ncurses "test_progs" rule.
2381 + amend change to CF_CC_ENV_FLAGS in 20160521 to make multilib build
2382 work (report by Sven Joachim).
2385 + build-fixes for ncurses-examples with NetBSD curses.
2386 + improve test/list_keys.c, fixing column-widths and sorting the list
2387 to make it more readable.
2390 + revise fix for Debian #805618 (report by Vlado Potisk, cf: 20151128).
2391 + modify test/ncurses.c a/A screens to make exiting on an escape
2392 character depend on the start of keypad and timeout modes, to allow
2393 better testing of function-keys.
2394 + modify rs1 for xterm-16color, xterm-88color and xterm-256color to
2395 reset palette using "oc" string as in linux -TD
2396 + use ANSI reply for u8 in xterm-new, to reflect vt220-style responses
2397 that could be returned -TD
2398 + added a few capabilities fixed in recent vte -TD
2401 + correct logic for -f option in test/demo_terminfo.c
2402 + add test/list_keys.c
2405 + further workaround for PIE/PIC breakage which causes gpm to not link.
2406 + fix most cppcheck warnings, mostly style, in ncurses library.
2409 + improved manual page description of tset/reset versus window-size.
2410 + fixes to work with a slightly broken compiler configuration which
2411 cannot compile "Hello World!" without adding compiler options
2412 (report by Ola x Nilsson):
2413 + pass appropriate compiler options to the CF_PROG_CC_C_O macro.
2414 + when separating compiler and options in CF_CC_ENV_FLAGS, ensure
2415 that all options are split-off into CFLAGS or CPPFLAGS
2416 + restore some -I options removed in 20140726 because they appeared
2417 to be redundant. In fact, they are needed for a compiler that
2418 cannot combine -c and -o options.
2421 + regenerate HTML manpages.
2422 + improve manual pages for wgetch and wget_wch to point out that they
2423 might return values without names in curses.h (Debian #822426).
2424 + make linux3.0 entry the default linux entry (Debian #823658) -TD
2425 + modify linux2.6 entry to improve line-drawing so that the linux3.0
2426 entry can be used in non-UTF-8 mode -TD
2427 + document return value of use_extended_names (report by Mike Gran).
2430 + amend change to _nc_do_color to restore the early return for the
2431 special case used in _nc_screen_wrap (report by Dick Streefland,
2433 + modify test/ncurses.c:
2434 + check return-value of putwin
2435 + correct ifdef which made the 'g' test's legend not reflect changes
2436 to keypad- and scroll-modes.
2437 + correct return-value of extended putwin (report by Mike Gran).
2440 + modify test/ncurses.c 'd' edit-color menu to optionally read xterm
2441 color palette directly from terminal, as well as handling KEY_RESIZE
2442 and screen-repainting with control/L and control/R.
2443 + add 'oc' capability to xterm+256color, allowing palette reset for
2447 + add workaround in configure script for inept transition to PIE vs
2448 PIC builds documented in
2449 https://fedoraproject.org/wiki/Changes/Harden_All_Packages
2450 + add "reset" to list of programs whose names might change in manpages
2451 due to program-transformation configure options.
2452 + drop long-obsolete "-n" option from tset.
2455 + modify test/blue.c to use Unicode values for card-glyphs when
2456 available, as well as improving the check for CP437 and CP850.
2459 + regenerate HTML manpages.
2460 + improve manual pages for utilities with respect to POSIX versus
2464 + regenerate HTML manpages.
2465 + improve test/demo_menus.c, allowing mouse-click on the menu-headers
2466 to switch the active menu. This requires a new extension option
2467 O_MOUSE_MENU to tell the menu driver to put mouse events which do not
2468 apply to the active menu back into the queue so that the application
2469 can handle the event.
2472 + improve description of tgoto parameters (report by Steffen Nurpmeso).
2473 + amend workaround for Solaris line-drawing to restore a special case
2474 that maps Unicode line-drawing characters into the acsc string for
2475 non-Unicode locales (Debian #816888).
2478 + modified test/filter.c to illustrate an alternative to getnstr, that
2479 polls for input while updating a clock on the right margin as well
2480 as responding to window size-changes.
2483 + omit a redefinition of "inline" when traces are enabled, since this
2484 does not work with gcc 5.3.x MinGW cross-compiling (cf: 20150912).
2487 + modify test/configure script to check for pthread dependency of
2488 ncursest or ncursestw library when building ncurses examples, e.g.,
2489 in case weak symbols are used.
2490 + modify configure macro for shared-library rules to use -Wl,-rpath
2491 rather than -rpath to work around a bug in scons (FreeBSD #178732,
2493 + double-width multibyte characters were not counted properly in
2494 winsnstr and wins_nwstr (report/example by Eric Pruitt).
2495 + update config.guess, config.sub from
2496 http://git.savannah.gnu.org/cgit/config.git
2499 + amend fix for _nc_ripoffline from 20091031 to make test/ditto.c work
2500 in threaded configuration.
2501 + move _nc_tracebits, _tracedump and _tracemouse to curses.priv.h,
2502 since they are not part of the suggested ABI6.
2505 + define WIN32_LEAN_AND_MEAN for MinGW port, making builds faster.
2506 + modify test/ditto.c to allow $XTERM_PROG environment variable to
2507 override "xterm" as the name of the program to run in the threaded
2511 + improve formatting of man/curs_refresh.3x and man/tset.1 manpages
2512 + regenerate HTML manpages using newer man2html to eliminate some
2513 unwanted blank lines.
2516 + ifdef'd header-file definition of mouse_trafo() with NCURSES_NOMACROS
2517 (report by Corey Minyard).
2518 + fix some strict compiler-warnings in traces.
2521 + tidy up comments about hardcoded 256color palette (report by
2522 Leonardo Brondani Schenkel) -TD
2523 + add putty-noapp entry, and amend putty entry to use application mode
2524 for better consistency with xterm (report by Leonardo Brondani
2526 + modify _nc_viscbuf2() and _tracecchar_t2() to trace wide-characters
2527 as a whole rather than their multibyte equivalents.
2528 + minor fix in wadd_wchnstr() to ensure that each cell has nonzero
2530 + move PUTC_INIT calls next to wcrtomb calls, to avoid carry-over of
2531 error status when processing Unicode values which are not mapped.
2534 + modify ncurses c/C color test-screens to take advantage of wide
2535 screens, reducing the number of lines used for 88- and 256-colors.
2536 + minor refinement to check versus ncv to ignore two parameters of
2537 SGR 38 and 48 when those come from color-capabilities.
2540 + add check in tic for use of bold, etc., video attributes in the
2541 color capabilities, accounting whether the feature is listed in ncv.
2542 + add check in tic for conflict between ritm, rmso, rmul versus sgr0.
2545 + add a paragraph to curs_getch.3x discussing key naming (discussion
2546 with James Crippen).
2547 + amend workaround for Solaris vs line-drawing to take the configure
2549 + add a configure check for wcwidth() versus the ncurses line-drawing
2550 characters, to use in special-casing systems such as Solaris.
2553 + improve CF_XOPEN_CURSES macro used in test/configure, to define as
2554 needed NCURSES_WIDECHAR for platforms where _XOPEN_SOURCE_EXTENDED
2555 does not work. Also modified the test program to ensure that if
2556 building with ncurses, that the cchar_t type is checked, since that
2557 normally is since 20111030 ifdef'd depending on this test.
2558 + improve 20121222 workaround for broken acs, letting Solaris "work"
2559 in spite of its misconfigured wcwidth which marks all of the line
2560 drawing characters as double-width.
2563 + update form_cursor.3x, form_post.3x, menu_attributes.3x to list
2564 function names in NAME section (patch by Jason McIntyre).
2565 + minor fixes to manpage NAME/SYNOPSIS sections to consistently use
2566 rule that either all functions which are prototyped in SYNOPSIS are
2567 listed in the NAME section, or the manual-page name is the sole item
2568 listed in the NAME section. The latter is used to reduce clutter,
2569 e.g., for the top-level library manual pages as well as for certain
2570 feature-pages such as SP-funcs and threading (prompted by patches by
2574 + add option to preserve leading whitespace in form fields (patch by

2587 + add keys f12-f124 to pccon+keys (Tati Chevron).
2588 + add test/test_sgr.c program to exercise all combinations of sgr.
2591 + modify tset's assignment to TERM in its output to reflect the name by
2592 which the terminal description is found, rather than the primary
2593 name. That was an unnecessary part from the initial conversion of
2594 tset from termcap to terminfo. The termcap program in 4.3BSD did
2595 this to avoid using the short 2-character name (report by Rich
2597 + minor fix to configure script to ensure that rules for resulting.map
2598 are only generated when needed (cf: 20151101).
2599 + modify configure script to handle the case where tic-library is
2600 renamed, but the --with-debug option is used by itself without
2601 normal or shared libraries (prompted by comment in Debian #803482).
2604 + amend change for pkg-config which allows build of pc-files when no
2605 valid pkg-config library directory was configured to suppress the
2606 actual install if it is not overridden to a valid directory at
2607 install time (cf: 20150822).
2608 + modify editing script which generates resulting.map to work with the
2609 clang configuration on recent FreeBSD, which gives an error on an
2610 empty "local" section.
2611 + fix a spurious "(Part)" message in test/ncurses.c b/B tests due
2612 to incorrect attribute-masking.
2615 + modify MKexpanded.sh to update the expansion of a temporary filename
2616 to "expanded.c", for use in trace statements.
2617 + modify layout of b/B tests in test/ncurses.c to allow for additional
2618 annotation on the right margin; some terminals with partial support
2619 did not display well.
2620 + fix typo in curs_attr.3x (patch by Sven Joachim).
2621 + fix typo in INSTALL (patch by Tomas Cech).
2622 + improve configure check for setting WILDCARD_SYMS variable; on ppc64
2623 the variable is in the Data section rather than Text (patch by Michel
2624 Normand, Novell #946048).
2625 + using configure option "--without-fallbacks" incorrectly caused
2626 FALLBACK_LIST to be set to "no" (patch by Tomas Cech).
2627 + updated minitel entries to fix kel problem with emacs, and add
2628 minitel1b-nb (Alexandre Montaron).
2629 + reviewed/updated nsterm entry Terminal.app in OSX -TD
2630 + replace some dead URLs in comments with equivalents from the
2631 Internet Archive -TD
2632 + update config.guess, config.sub from

2637 (Debian #801864, patch by Esa Peuha).
2638 + remove an early-return from _nc_do_color, which can interfere with
2639 data needed by bkgd when ncurses is configured with extended colors
2640 (patch by Denis Tikhomirov).

2654 fallback in case there is no valid terminal on the standard input
2655 (prompted by discussion on bug-ncurses mailing list, Debian #676461).
2658 + change makefile rule for removing resulting.map to distclean rather
2660 + add /lib/terminfo to terminfo-dirs in ".deb" test-package.
2661 + add note on portability of resizeterm and wresize to manual pages.
2664 + clarify in resizeterm.3x how KEY_RESIZE is pushed onto the input
2666 + clarify in curs_getch.3x that the keypad mode affects ability to
2667 read KEY_MOUSE codes, but does not affect KEY_RESIZE.
2668 + add overlooked build-fix needed with Cygwin for separate Ada95
2669 configure script, cf: 20150606 (report by Nicolas Boulenguez)
2672 + fixes for configure/build using clang on OSX (prompted by report by
2674 + do not redefine "inline" in ncurses_cfg.h; this was originally to
2675 solve a problem with gcc/g++, but is aggravated by clang's misuse
2676 of symbols to pretend it is gcc.
2677 + add braces to configure script to prevent unwanted add of
2678 "-lstdc++" to the CXXLIBS symbol.

2740 curs_initscr.3x page.
2741 + modify logic in make_keys.c to not assume anything about the size
2742 of strnames and strfnames variables, since those may be functions

2780 + fix overflow warning for OSX with lib_baudrate.c (cf: 20010630).
2781 + modify script used to generate map/sym files to mark 5.9.20150530 as
2782 the last "5.9" version, and regenerated the files. That makes the
2783 files not use ".current" for the post-5.9 symbols. This also
2784 corrects the label for _nc_sigprocmask used in when weak symbols are
2785 configured for the ncursest/ncursestw libraries (prompted by

2798 ncurses package scripts work when present for cross-compiling, as the
2799 lessor of two evils (cf: 20150530).
2800 + add check in configure script to disallow conflicting options

2829 ncurses-examples for consistency with Debian, to work with package
2831 + regenerate html manpages.
2832 + clarify handling of carriage return in waddch manual page; it was
2833 discussed only in the portability section (prompted by comment on
2834 Stack Overflow forum):
2837 + add test-packages for cross-compiling ncurses-examples using the
2838 MinGW test-packages. These are only the Debian packages; RPM later.
2839 + cleanup format of debian/copyright files
2840 + add pc-files to the MinGW cross-compiling test-packages.
2841 + correct a couple of places in gen-pkgconfig.in to handle renaming of

2858 + add sample "magic" file, to document ext-putwin.
2859 + modify gen-pkgconfig.in to add explicit -ltinfo, etc., to the
2860 generated ".pc" file when ld option "--as-needed" is used, or when

2866 + make extra-suffix work for OSX configuration, e.g., for shared
2868 + modify Ada95/configure script to work with pkg-config
2869 + move test-package for ncurses6 to /usr, since filename-conflicts have
2871 + corrected build rules for Ada95/gen/generate; it does not depend on
2872 the ncurses library aside from headers.
2873 + reviewed man pages, fixed a few other spelling errors.

2953 and add those to the *-config and *.pc files, to simplify use for
2954 the wide-character libraries.
2955 + modify ncurses.spec to accommodate Fedora21's location of pkg-config
2957 + correct sense of "--disable-lib-suffixes" configure option (report

2993 cross-compiles. Also drop "-Bsharable" option from shared-library
2994 rules for FreeBSD and DragonFly (FreeBSD #196592).
2995 + fix a memory leak in form library Free_RegularExpression_Type()
2996 (report by Pavel Balaev).
2999 + modify_nc_flush() to retry if interrupted (patch by Stian Skjelstad).
3000 + change map files to make _nc_freeall a global, since it may be used

3027 ".pc" files and the corresponding library. Use this in the test
3028 package for ncurses6.
3029 + modify configure script so that if pkg-config is not installed, it
3030 is still possible to install ".pc" files (report by Misty De Meo).
3031 + updated ".sym" files, removing symbols which are marked as "local"
3032 in the corresponding ".map" files.
3033 + updated ".map" files to reflect move of comp_captab and comp_hash
3034 from tic-library to tinfo-library in 20090711 (report by Sven
3038 + updated ".map" files so that each symbol that may be shared across
3039 the different library configurations has the same label. Some
3040 review is needed to ensure these are really compatible.
3041 + modify MKlib_gen.sh to work around change in development version of
3042 gcc introduced here:
3043 https://gcc.gnu.org/ml/gcc-patches/2014-06/msg02185.html
3044 https://gcc.gnu.org/ml/gcc-patches/2014-07/msg00236.html
3045 (reports by Marcus Shawcroft, Maohui Lei).
3046 + improved configure macro CF_SUBDIR_PATH, from lynx changes.
3049 + improved ".map" files by generating them with a script that builds
3050 ncurses with several related configurations and merges the results.
3051 A further refinement is planned, to make the tic- and tinfo-library
3052 symbols use the same versions across each of the four configurations
3053 which are represented (reports by Sven Joachim, Werner Fink).
3056 + improve description of limits for color values and color pairs in
3057 curs_color.3x (prompted by patch by Tim van der Molen).
3058 + add VERSION file, using first field in that to record the ABI version
3059 used for configure --with-libtool --disable-libtool-version
3060 + add configure options for applying the ".map" and ".sym" files to
3061 the ncurses, form, menu and panel libraries.
3062 + add ".map" and ".sym" files to show exported symbols, e.g., for

3067 and making a new TRACE_RETURN1 macro for cases where the cast does
3071 + in-progress changes to integrate the win32 console driver with the
3072 msys2 configuration.

3089 + minor formatting fixes to _nc_trace_mmask_t, make this function
3090 exported to help with debugging mouse changes.
3091 + improve behavior of wheel-mice for xterm protocol, noting that there

3096 + implement decoder for xterm SGR 1006 mouse mode.
3099 + implement curs_set in win_driver.c
3100 + implement flash in win_driver.c
3101 + fix an infinite loop in win_driver.c if the command-window loses
3103 + improve the non-buffered mode, i.e., NCURSES_CONSOLE2, of
3104 win_driver.c by temporarily changing the buffer-size to match the
3105 window-size to eliminate the scrollback. Also enforce a minimum
3106 screen-size of 24x80 in the non-buffered mode.
3107 + modify generated misc/Makefile to suppress install.data from the
3108 dependencies if the --disable-db-install option is used, compensating
3109 for the top-level makefile changes used to add ncurses*-config in the
3110 20140920 changes (report by Steven Honeyman).
3113 + add ncurses*-config to bin-directory of sample package-scripts.
3114 + add check to ensure that getopt is available; this is a problem in
3115 some older cross-compiler environments.

3205 NCURSES_CONSOLE2 is set (cf: 20140503).
3206 + reorganize b/B menu items in ncurses.c, putting the test-strings into
3207 subwindows. This is needed for a planned change to use Unicode
3208 fullwidth characters in the test-screens.
3209 + correct update to form status for _NEWTOP, broken by fixes for
3210 compiler warnings (patch by Leon Winter, cf: 20120616).
3213 + change shared-library suffix for AIX 5 and 6 to ".so", avoiding
3214 conflict with the static library (report by Ben Lentz).
3215 + document RPATH_LIST in INSTALLATION file, as part of workarounds for
3216 upgrading an ncurses library using the "--with-shared" option.
3217 + modify test/ncurses.c c/C tests to cycle through subsets of the
3218 total number of colors, to better illustrate 8/16/88/256-colors by
3219 providing directly comparable screens.
3220 + add test/dots_curses.c, for comparison with the low-level examples.
3223 + fix dereference before null check found by Coverity in tic.c
3225 + fix sign-extension bug in read_entry.c which prevented "toe" from
3226 reading empty "screen+italics" entry.
3227 + modify sgr for screen.xterm-new to support dim capability -TD
3228 + add dim capability to nsterm+7 -TD
3229 + cancel dim capability for iterm -TD
3230 + add dim, invis capabilities to vte-2012 -TD
3231 + add sitm/ritm to konsole-base and mlterm3 -TD
3234 > fix regression in screen terminfo entries (reports by Christian
3235 Ebert, Gabriele Balducci) -TD
3236 + revert the change to screen; see notes for why this did not work -TD
3237 + cancel sitm/ritm for entries which extend "screen", to work around
3238 screen's hardcoded behavior for SGR 3 -TD
3241 + separate masking for sgr in vidputs from sitm/ritm, which do not
3242 overlap with sgr functionality.
3243 + remove unneeded -i option from adacurses-config; put -a in the -I
3244 option for consistency (patch by Pascal Pignard).
3245 + update xterm-new terminfo entry to xterm patch #305 -TD
3246 + change format of test-scripts for Debian Ada95 and ncurses-examples
3247 packages to quilted to work around Debian #700177 (cf: 20130907).
3248 + build fix for form_driver_w.c as part of ncurses-examples package for
3249 older ncurses than 20131207.
3250 + add Hello World example to adacurses-config manpage.
3251 + remove unused --enable-pc-files option from Ada95/configure.
3252 + add --disable-gnat-projects option for testing.
3253 + revert changes to Ada95 project-files configuration (cf: 20140524).
3254 + corrected usage message in adacurses-config.
3257 + fix typo in ncurses manpage for the NCURSES_NO_MAGIC_COOKIE
3258 environment variable.
3259 + improve discussion of input-echoing in curs_getch.3x
3260 + clarify discussion in curs_addch.3x of wrapping.
3261 + modify parametrized.h to make fln non-padded.
3262 + correct several entries which had termcap-style padding used in
3263 terminfo: adm21, aj510, alto-h19, att605-pc, x820 -TD
3264 + correct syntax for padding in some entries: dg211, h19 -TD
3265 + correct ti924-8 which had confused padding versus octal escapes -TD
3266 + correct padding in sbi entry -TD
3267 + fix an old bug in the termcap emulation; "%i" was ignored in tparm()
3268 because the parameters to be incremented were already on the internal
3269 stack (report by Corinna Vinschen).
3270 + modify tic's "-c" option to take into account the "-C" option to
3271 activate additional checks which compare the results from running
3272 tparm() on the terminfo expressions versus the translated termcap
3274 + modify tic to allow it to read from FIFOs (report by Matthieu Fronton,
3276 > patches by Nicolas Boulenguez:
3277 + explicit dereferences to suppress some style warnings.
3278 + when c_varargs_to_ada.c includes its header, use double quotes
3280 + samples/ncurses2-util.adb: removed unused with clause. The warning
3281 was removed by an obsolete pragma.
3282 + replaced Unreferenced pragmas with Warnings (Off). The latter,
3283 available with older GNATs, needs no configure test. This also
3284 replaces 3 untested Unreferenced pragmas.
3285 + simplified To_C usage in trace handling. Using two parameters allows
3286 some basic formatting, and avoids a warning about security with some
3288 + for generated Ada sources, replace many snippets with one pure
3290 + removed C_Chtype and its conversions.
3291 + removed C_AttrType and its conversions.
3292 + removed conversions between int, Item_Option_Set, Menu_Option_Set.
3293 + removed int, Field_Option_Set, Item_Option_Set conversions.
3294 + removed C_TraceType, Attribute_Option_Set conversions.
3295 + replaced C.int with direct use of Eti_Error, now enumerated. As it
3296 was used in a case statement, values were tested by the Ada compiler
3297 to be consecutive anyway.
3298 + src/Makefile.in: remove duplicate stanza
3299 + only consider using a project for shared libraries.
3300 + style. Silent gnat-4.9 warning about misplaced "then".
3301 + generate shared library project to honor ADAFLAGS, LDFLAGS.
3304 + cleanup recently introduced compiler warnings for MingW port.
3305 + workaround for ${MAKEFLAGS} configure check versus GNU make 4.0,
3306 which introduces more than one gratuitous incompatibility.
3309 + add vt520ansi terminfo entry (patch by Mike Gran)
3310 + further improve MinGW support for the scenario where there is an
3311 ANSI-escapes handler such as ansicon running in the console window
3312 (patch by Juergen Pfeifer).
3315 + add --disable-lib-suffixes option (adapted from patch by Juergen
3317 + merge some changes from Juergen Pfeifer's work with MSYS2, to
3318 simplify later merging:
3319 + use NC_ISATTY() macro for isatty() in library
3320 + add _nc_mingw_isatty() and related functions to windows-driver
3321 + rename terminal driver entrypoints to simplify grep's
3322 + remove a check in the sp-funcs flavor of newterm() which allowed only
3323 the first call to newterm() to succeed (report by Thomas Beierlein,
3327 + update config.guess, config.sub from
3328 http://git.savannah.gnu.org/cgit/config.git
3331 + modify configure script:
3332 + drop the -no-gcc option from Intel compiler, from lynx changes.
3333 + extend the --with-hashed-db configure option to simplify building
3334 with different versions of Berkeley database using FreeBSD ports.
3335 + improve initialization for MinGW port (Juergen Pfeifer):
3336 + enforce Windows-style path-separator if cross-compiling,
3337 + add a driver-name method to each of the drivers,
3338 + allow the Windows driver name to match "unknown", ignoring case,
3339 + lengthen the built-in name for the Windows console driver to
3340 "#win32console", and
3341 + move the comparison of driver-names allowing abbreviation, e.g.,
3342 to "#win32con" into the Windows console driver.
3345 + add check in tic for mismatch between ccc and initp/initc
3346 + cancel ccc in putty-256color and konsole-256color for consistency
3347 with the cancelled initc capability (patch by Sven Zuhlsdorf).
3348 + add xterm+256setaf building block for various terminals which only
3349 get the 256-color feature half-implemented -TD
3350 + updated "st" entry (leaving the 0.1.1 version as "simpleterm") to
3354 + fix typo in "mlterm" entry (report by Gabriele Balducci) -TD
3357 + use types from <stdint.h> in sample build-scripts for chtype, etc.
3358 + modify configure script and curses.h.in to allow the types specified
3359 using --with-chtype and related options to be defined in <stdint.h>
3360 + add terminology entry -TD
3361 + add mlterm3 entry, use that as "mlterm" -TD
3362 + inherit mlterm-256color from mlterm -TD
3365 + modify _nc_New_TopRow_and_CurrentItem() to ensure that the menu's
3366 top-row is adjusted as needed to ensure that the current item is
3367 on the screen (patch by Johann Klammer).
3368 + add wgetdelay() to retrieve _delay member of WINDOW if it happens to
3369 be opaque, e.g., in the pthread configuration (prompted by patch by
3373 + modify ifdef in read_entry.c to handle the case where
3374 NCURSES_USE_DATABASE is not defined (patch by Xin Li).
3375 + add cast in form_driver_w() to fix ARM build (patch by Xin Li).
3376 + add logic to win_driver.c to save/restore screen contents when not
3377 allocating a console-buffer (cf: 20140215).
3380 + clarify error-returns from newwin (report by Ruslan Nabioullin).
3383 + fix some compiler warnings in win_driver.c
3384 + updated notes for wsvt25 based on tack and vttest -TD
3385 + add teken entry to show actual properties of FreeBSD's "xterm"
3389 + in-progress changes to win_driver.c to implement output without
3390 allocating a console-buffer. This uses a pre-existing environment
3391 variable NCGDB used by Juergen Pfeifer for debugging (prompted by
3392 discussion with Erwin Waterlander regarding Console2, which hangs
3393 when reading in an allocated console-buffer).
3394 + add -t option to gdc.c, and modify to accept "S" to step through the
3396 + regenerate NCURSES-Programming-HOWTO.html to fix some of the broken
3397 html emitted by docbook.
3400 + modify CF_XOPEN_SOURCE macro to omit followup check to determine if
3401 _XOPEN_SOURCE can/should be defined. g++ 4.7.2 built on Solaris 10
3402 has some header breakage due to its own predefinition of this symbol
3403 (report by Jean-Pierre Flori, Sage #15796).
3406 + add/use symbol NCURSES_PAIRS_T like NCURSES_COLOR_T, to illustrate
3407 which "short" types are for color pairs and which are color values.
3408 + fix build for s390x, by correcting field bit offsets in generated
3409 representation clauses when int=32 long=64 and endian=big, or at
3410 least on s390x (patch by Nicolas Boulenguez).
3411 + minor cleanup change to test/form_driver_w.c (patch by Gaute Hope).
3414 + remove unnecessary ifdef's in Ada95/gen/gen.c, which reportedly do
3415 not work as is with gcc 4.8 due to fixes using chtype cast made for
3416 new compiler warnings by gcc 4.8 in 20130824 (Debian #735753, patch
3417 by Nicolas Boulenguez).
3420 + apply includesubdir variable which was introduced in 20130805 to
3421 gen-pkgconfig.in (Debian #735782).
3424 + further improved man2html, used this to fix broken links in html
3426 ftp://ftp.invisible-island.net/ncurses/patches/man2html
3429 + modify configure-script/ifdef's to allow OLD_TTY feature to be
3430 suppressed if the type of ospeed is configured using the option
3431 --with-ospeed to not be a short. By default, it is a short for
3432 termcap-compatibility (adapted from suggestion by Christian
3434 + correct a typo in _nc_baudrate() (patch by Christian Weisgerber,
3436 + fix a few -Wlogical-op warnings.
3437 + updated llib-l* files.
