<ul>
<li>
- <p><a href=
- "@HOMEPAGE@/man/form_field_opts.3x.html">O_EDGE_INSERT_STAY</a>
- tells the form library to optionally delay cursor movement on
- a field edge/boundary</p>
+ <p>A new (experimental) driver, for the Windows Terminal
+ configuration is provided.</p>
</li>
<li>
- <p><a href=
- "@HOMEPAGE@/man/form_field_opts.3x.html">O_INPUT_FIELD</a>
- extension to form library allows a dynamic field to shrink if
- the new limit is smaller than the current field size.</p>
- </li>
-
- <li>
- <p>added <a href=
- "@HOMEPAGE@/man/curs_memleaks.3x.html">exit_curses</a> and
- <a href=
- "@HOMEPAGE@/man/curs_memleaks.3x.html">exit_terminfo</a> to
- replace internal symbols for leak-checking.</p>
- </li>
-
- <li>
- <p>added <a href=
- "@HOMEPAGE@/man/curs_trace.3x.html#h3-Functions">curses_trace</a>,
- to replace trace().</p>
+ <p>A script is provided which enables <a href=
+ "@HOMEPAGE@/ncurses-openbsd.html">OpenBSD</a> users to
+ upgrade their system to use ncurses 6.3 (OpenBSD developers
+ are also invited to do this).</p>
</li>
</ul>
<ul>
<li>
- <p>mouse decoding now handles shift/control/alt logic when
- decoding xterm's 1006 mode</p>
- </li>
-
- <li>
- <p>ncurses now defines a limit for <a href=
- "@HOMEPAGE@/man/curs_getstr.3x.html">wgetnstr</a>, <a href=
- "@HOMEPAGE@/man/curs_get_wstr.3x.html">wgetn_wstr</a> when
- length is negative or “too large”.</p>
- </li>
-
- <li>reordered loop-limit checks in <a href=
- "@HOMEPAGE@/man/curs_insstr.3x.html">winsnstr</a> in case the
- string has no terminating null and only the number of
- characters is used.</li>
-
- <li>
- <p>there is now no buffer-size limit when reading the
- <a href="@HOMEPAGE@/man/ncurses.3x.html#h3-TERMCAP"><tt>$TERMCAP</tt></a>
- variable.</p>
- </li>
-
- <li>
- <p>the <a href=
- "@HOMEPAGE@/man/ncurses.3x.html#h3-TERMCAP"><tt>$TERMCAP</tt></a>
- variable may be interpreted as a fallback to a terminfo
- entry</p>
- </li>
-
- <li>
- <p><a href=
- "@HOMEPAGE@/man/curs_terminfo.3x.html#h3-Output-Functions"><tt>
- mvcur</tt></a> now decides whether to use hard-tabs, using
- <strong><tt>xt</tt></strong>, <strong><tt>tbc</tt></strong>
- and <strong><tt>hts</tt></strong> as clues.</p>
- </li>
-
- <li>
- <p>extended colors are improved by modifying an internal call
- to <a href=
- "@HOMEPAGE@/man/curs_terminfo.3x.html#h3-Output-Functions"><tt>
- vid_puts</tt></a> to pass extended color pairs e.g., from
- <tt>tty_update.c</tt> and <tt>lib_mvcur.c</tt></p>
+ <p>modify lib_mouse.c to check for out-of-range button
+ numbers, convert those to position reports.</p>
</li>
<li>
- <p id="getenv-fixes">the initialization functions now avoid
- relying upon persistent data for the result from <a href=
- "#getenv-check"><tt>getenv</tt></a></p>
- </li>
-
- <li>
- <p>scrolling is improved:</p>
-
- <ul>
- <li>a limit check in <tt>newline_forces_scroll</tt> handles
- the case where the row is inside scroll-margins, but not at
- the end.</li>
-
- <li>
- <p>improved loop limits in <tt>_nc_scroll_window</tt>
- handle a case where the scrolled data is a pad which is
- taller than the window.</p>
- </li>
- </ul>
+ <p>add sp-funcs for <a href=
+ "@HOMEPAGE@/man/curs_termattrs.3x.html#h3-erasechar_-erasewchar">
+ erasewchar</a>, <a href=
+ "@HOMEPAGE@/man/curs_termattrs.3x.html#h3-killchar_-killwchar">
+ killwchar</a>.</p>
</li>
</ul>
<p>These are revised features:</p>
<ul>
- <li>
- <p>used “<tt>const</tt>” in some prototypes
- rather than <tt>NCURSES_CONST</tt> where X/Open Curses was
- updated to do this, e.g., <tt>wscanw</tt>, <tt>newterm</tt>,
- the terminfo interface. Also use “<tt>const</tt>”
- for consistency in the termcap interface, which was withdrawn
- by X/Open Curses in Issue 5 (2007). As of Issue 7, X/Open
- Curses still lacks “<tt>const</tt>” for certain
- return values, e.g., <a href=
- "@HOMEPAGE@/man/curs_util.3x.html#h3-keyname_key_name">keyname</a>.</p>
- </li>
-
- <li>
- <p>modified <a href=
- "@HOMEPAGE@/man/curs_bkgd.3x.html#h3-bkgd"><tt>wbkgd</tt></a>
- and <a href=
- "@HOMEPAGE@/man/curs_bkgrnd.3x.html#h3-bkgrnd"><tt>wbkgrnd</tt></a>
- to improve compatibility with SVr4 curses, changing the way
- the window rendition is updated when the background character
- is modified</p>
- </li>
-
- <li>
- <p>improved terminfo write/read by modifying the fourth item
- of the extended header to denote the number of valid strings
- in the extended string table (see <a href=
- "@HOMEPAGE@/man/term.5.html#h3-EXTENDED-STORAGE-FORMAT">term(5)</a>).</p>
- </li>
-
- <li>
- <p>modified the initialization checks for mouse so that the
- <a href=
- "/ncurses/terminfo.src.html#tic-xterm_sm_1006"><tt>xterm+sm+1006</tt></a>
- block will work with terminal descriptions not mentioning
- <em>xterm</em>.</p>
- </li>
+ <li>modify wgetnstr, wgetn_wstr to improve compatibility with
+ SVr4 curses in its treatment of interrupt and quit
+ characters</li>
</ul>
<p>These were done to limit or ultimately deprecate features:</p>
<ul>
<li>
- <p>deprecated <a href=
- "@HOMEPAGE@/NEWS.html#t970831">safe-sprintf</a>, since the
- <tt>vsnprintf</tt> function, which does what was needed, was
- standardized long ago.</p>
- </li>
+ <p>mark wgetch-events feature as deprecated.</p>
- <li>
- <p>marked <a href=
- "@HOMEPAGE@/man/curs_printw.3x.html#h2-PORTABILITY"><tt>vwprintw</tt></a>
- and <tt>vwscanw</tt> as deprecated; recommend using <a href=
- "@HOMEPAGE@/man/curs_printw.3x.html"><tt>vw_printw</tt></a>
- and <tt>vw_scanw</tt>, respectively.</p>
- </li>
+ <ul>
+ <li>
+ <p>prevent <tt>KEY_EVENT</tt> from appearing in
+ <tt>curses.h</tt> unless the configure option
+ <code>--enable-wgetch-events</code> is used.</p>
+ </li>
- <li>
- <p>added deprecation warnings for internal functions called
- by older versions of <a href=
- "@HOMEPAGE@/tack.html">tack</a>.</p>
+ <li>
+ <p>modify <tt>MKkey_defs.sh</tt> to hide ncurses'
+ definition of <tt>KEY_EVENTS</tt> to reduce <em>Visual
+ Studio C++</em> redefinition warnings.</p>
+ </li>
+ </ul>
</li>
<li>
- <p>removed unused <tt>_nc_import_termtype2</tt> function.</p>
+ <p>reduce build-warnings by excluding ncurses-internals from
+ deprecation warnings.</p>
</li>
</ul>
<ul>
<li>
- <p>check parameter of <a href=
- "@HOMEPAGE@/man/curs_threads.3x.html">set_escdelay</a>,
- return ERR if negative.</p>
- </li>

- ERR if not greater than zero</p>
- </li>
-
- <li>
- <p>correct a status-check in _nc_read_tic_entry() so that if
- reading a hex/b64 <a href=
- "@HOMEPAGE@/man/ncurses.3x.html#h3-TERMINFO"><tt>$TERMINFO</tt></a>,
- and the <a href=
- "@HOMEPAGE@/man/ncurses.3x.html#h3-TERM"><tt>$TERM</tt></a>
- does not match, fall-through to the compiled-in search
- list.</p>
- </li>
-
- <li>
- <p>amend check for <a href=
- "@HOMEPAGE@/man/terminfo.5.html#h3-Predefined-Capabilities"><tt>
- repeat_char</tt></a> to handle a case where setlocale() was
- called after <a href=
- "@HOMEPAGE@/man/curs_initscr.3x.html"><tt>initscr</tt></a></p>
- </li>
-
- <li>
- <p>move macro for <a href=
- "@HOMEPAGE@/man/curs_touch.3x.html"><tt>is_linetouched</tt></a>
- inside <strong><tt>NCURSES_NOMACROS</tt></strong>
- <em><tt>ifndef</tt></em>.</p>
- </li>
-
- <li>
- <p>use <tt>_nc_copy_termtype2</tt> rather than direct
- assignment in <a href=
- "@HOMEPAGE@/man/curs_terminfo.3x.html#h3-Initialization">setupterm</a>,
- in case it is called repeatedly using fallback terminfo
- descriptions</p>
+ <p>drop symbols <em>GCC_PRINTF</em> and <em>GCC_SCANF</em>
+ from <curses.h>, to simplify use.</p>
</li>
<li>
- <p>improve workaround for Solaris wcwidth versus line-drawing
- characters</p>
+ <p>apply gcc format attribute to prototypes which use a
+ va_list parameter rather than a “<tt>...</tt>”
+ variable-length parameter list.</p>
</li>
<li>
- <p>add checks in <a href=
- "@HOMEPAGE@/man/resizeterm.3x.html"><tt>repair_subwindows</tt></a>
- to keep the current position and scroll-margins inside the
- resized subwindow.</p>
+ <p>modify <term.h> so that it is not necessary to
+ include <curses.h> before <term.h>.</p>
</li>
<li>
- <p>correct a buffer-limit in <tt>write_entry.c</tt> for
- systems that use caseless filenames.</p>
- </li>
-
- <li>
- <p>improved build-time utility <em>report_offsets</em>:</p>
-
- <ul>
- <li>
- <p>add categories, e.g., "w" for wide-character, "t" for
- threads to make the report more readable. Reorganized the
- structures reported to make the categories more
- apparent.</p>
- </li>
-
- <li>
- <p>add <tt>NCURSES_GLOBALS</tt> and
- <tt>NCURSES_PRESCREEN</tt> to report to show how similar
- the different <em>libtinfo</em> configurations are.</p>
- </li>
- </ul>
+ <p>provide for wide-characters as background character in
+ wbkgrnd</p>
</li>
<li>
- <p>modified some header files to ensure that those include
- necessary files except for the previously-documented
- cases</p>
+ <p>improve parameter-checking for tparm, adding function
+ _nc_tiparm() to handle the most-used case, which accepts only
+ numeric parameters.</p>
</li>
<li>
- <p>added some traces in initialization to show whether a
- fallback entry is used.</p>
+ <p>use return-value from <em>vsnprintf</em> to reallocate as
+ needed to allow for buffers larger than the screen size.</p>
</li>
<li>
- <p>made minor optimization to reduce calls to
- _nc_reserve_pairs</p>
+ <p>add another <em>fflush(stdout)</em> in <em>_nc_flush</em>
+ to handle time-delays in the middle of strings such as flash
+ when the application uses low-level calls rather than
+ curses.</p>
</li>
</ul>
<ul>
<li>
- <p>fix a special case in <tt>PutAttrChar</tt> where a cell is
- marked as alternate-character set, but the terminal does not
- actually support the given graphic character. This would
- happen in an older terminal such as <em>vt52</em>, which
- lacks most line-drawing capability.</p>
- </li>
-
- <li>
- <p>corrected flag for "seq" method of db 1.8.5 interface,
- needed by toe on some of the BSDs.</p>
- </li>
-
- <li>
- <p>modify comparison in make_hash.c to correct a special case
- in collision handling for Caps-hpux11</p>
- </li>
-
- <li>
- <p>add extended_slk_color{,_sp} symbols to the appropriate
- package/*.{map,sym} files</p>
- </li>
-
- <li>
- <p>modify lib_setup to avoid calling pthread_self() without
- first verifying that the address is valid, i.e., for weak
- symbols</p>
+ <p>add a check to guard against <em>repeat_char</em> emitting
+ digits which could be interpreted as BSD-style padding when
+ <tt>--enable-bsdpad</tt> is configured.</p>
</li>
<li>
- <p>add a couple of broken-linker symbols to the list of
- versioned symbols to help with link-time optimization versus
- weak symbols.</p>
+ <p>check for screen size-change in <a href=
+ "@HOMEPAGE@/man/curs_scr_dump.3x.html">scr_init</a> and
+ <a href=
+ "@HOMEPAGE@/man/curs_scr_dump.3x.html">scr_restore</a>, in
+ case a screen dump does not match the current screen
+ dimensions</p>

- <p>Later, in (referring to a version from <a href=
- "https://git.suckless.org/st/commit/c0882f2ed1d7a2dd0fa2efa52157e6fc6fde3652.html">
- mid-2017</a>), a user asked to have it updated in
- ncurses.</p>
- </li>
+ "@HOMEPAGE@/man/curs_bkgrnd.3x.html#h3-bkgrnd">wbkgrnd</a> to
+ avoid storing a null in the background character, because it
+ may be used in cases where the corresponding 0x80 is not
+ treated as a null.</p>
- <li>
- <p>However, it had an error from the change in late 2016. The
- terminal description made what <em>tmux</em> expected to be
- <strong>string</strong> actually a
- <strong>boolean</strong>.</p>
-
- <p>Over the years, there were problems with each of
- simpleterm's terminal descriptions. I repaired those, and
- usually dealt with the problem.</p>
+ <p>This was a regression introduced in ncurses 6.2 (<a href=
+ "https://lists.gnu.org/archive/html/bug-ncurses/2020-03/msg00000.html">reported</a>
+ on the mailing list), for which the workaround was to specify
+ a blank for the background character.</p>
</li>
<li>
- <p>The difference in this case was that when compiling the
- terminal database, <em>tic</em> may have in memory the
- definitions for more than one terminal description (so that
- it can resolve “<tt>use=</tt>” clauses). Seeing
- two different types for the same name, in certain situations
- it would incorrectly merge the symbol tables for the two
- terminal descriptions.</p>
- </li>
-
- <li>
- <p>On simpleterm's side, their bug was finally fixed in
+ <p>remove output-related checks for <a href=
+ "@HOMEPAGE@/man/curs_outopts.3x.html">nl/nonl</a> (also
<a href=

- late 2019</a>, three years after the bug was created.</p>
- </li>
- </ul>
-
- <p>For ncurses, the elapsed time to fix this bug was less than
- three years. Someone reported a problem with the terminal
- description a few weeks after releasing ncurses 6.1 (in <a href=
- "https://github.com/tmux/tmux/issues/1264">tmux #1264</a>), and
- the terminal description was updated that week (ncurses patch
- <a href="@HOMEPAGE@/NEWS.html#t20180224">20180224</a>):</p>

- + correct Ss/Ms interchange in st-0.7 entry (tmux #1264) -TD
-</pre>
- </blockquote>
-
- <p>The larger part of that change added a check to prevent a
- simple merge of terminal descriptions where the same user-defined
- name was used with different types. But it raised some
- questions:</p>
-
- <ul>
- <li>
- <p>Was there a reliable way to manage terminal descriptions
- which used the same extended name in different ways?</p>
+ "https://lists.gnu.org/archive/html/bug-ncurses/2020-09/msg00018.html">
+ reported</a> on the mailing list).</p>
</li>
<li>
- <p>Should ncurses provide a registry of well-known extended
- names, with their types?</p>
- </li>
- </ul>
+ <p>improve tparm implementation of <tt>%P</tt> and
+ <tt>%g</tt>, more closely matching SVr4 terminfo. Those
+ denote <em>static</em> and <em>dynamic</em> variables in
+ terminfo expressions.</p>
- <p>Since the correction to <a href=
- "@HOMEPAGE@/ncurses.html#download_database"><tt>terminfo.src</tt></a>
- could have been readily adopted by packagers, there was nothing
- more to be done from ncurses' standpoint on that part. But
- improving ncurses to prevent issues like that is the reason for
- making a release.</p>
-
- <p>Nothing more (constructive) was mentioned with regard to
- simpleterm. But a few problems were found in the handling of
- user-defined capabilities:</p>
-
- <ul>
- <li>
- <p>Forward-references to user-defined capabilities in a
- “<tt>use=</tt>” clause did not allocate new data
- for each use. In <em>tic</em>, successive compilation of
- terminal entries could add user-defined capabilities to the
- wrong terminal entry.</p>
-
- <p>This was not noticed before, since xterm's terminal
- descriptions were the main users of the feature, and almost
- all of the uses of the building-blocks which contained
- user-defined capabilities were backward-references.</p>
- </li>
-
- <li>
- <p>There is one (documented) case where ncurses 6.1 supports
- a user-defined capability that could be any type (i.e.,
- “RGB”). The check added in February 2018 to guard
- against mismatches did not handle all of the combinations
- needed.</p>
+ <p>Exactly what those terms meant was never documented before
+ in any implementation of curses, aside from source code.
+ Unlike the other two fixes, the problem was discovered while
+ studying OpenBSD's version of <a href=
+ "@HOMEPAGE@/ncurses-openbsd.html#issue_tput">tset</a>.</p>
</li>
</ul>
- <p>Both of these issues dated from the original implementation of
- user-defined capabilities. Fixing them does not change the
- terminal database, but a older <em>tic</em> without the fixes
- will not be able to handle terminfo sources which rely upon those
- fixes. Starting in June 2019, the download link for the terminfo
- source file was capped at that date. The development sources have
- an up-to-date copy of the file, for people with a legitimate need
- for it.</p>
-
- <p>The “<tt>-c</tt>” (check) option of <em>tic</em>
- is not very useful if it cannot offer advice on parameters needed
- for user-defined capabilities. The various <em>Caps</em> files
- were reorganized to reduce redundancy, and in the common portion
- (<a href=
- "https://github.com/ThomasDickey/ncurses-snapshots/blob/master/include/Caps-ncurses">Caps-ncurses</a>),
- a registry of user-defined capabilities is provided for use by
- <em>tic</em>. While users can still define their own custom
- capabilities, <em>tic</em> will not offer any advice when their
- parameters do not match.</p>
-
- <p>In ncurses 6.2, <em>tic</em> makes a special check to allow
- any type for <em>RGB</em>, but its being able to do this relies
- upon fixes made in the ncurses library in mid-2019.</p>
