-
- <h3><a name="h3-library" id="h3-library">Library
- improvements</a></h3>
-
- <h4><a name="h4-new-library" id="h4-new-library">New
- features</a></h4>
-
- <p>The improved integration of <span class=
- "part-name">tput</span> and <span class="part-name">tset</span>
- made only small changes to the libraries. However, supporting
- extended numeric capabilities required a few changes:</p>
-
- <ul>
- <li>
- <p>The <code>TERMINAL</code> structure in
- <code><term.h></code> is now opaque. Doing that allowed
- making the structure larger, to hold the extended numeric
- data.</p>
-
- <p>A few applications required changes during development of
- <span class="main-name">ncurses 6.1</span> because those
- applications misused the members of that structure, e.g.,
- directly modifying it rather than using <a href=
- "https://invisible-island.net/ncurses/man/curs_kernel.3x.html#h3-def_prog_mode_-def_shell_mode">
- def_prog_mode</a>.</p>
- </li>
-
- <li>
- <p>Having made <code>TERMINAL</code> opaque (and because none
- of the library functions use anything except a pointer to
- <code>TERMINAL</code>), it was possible to increase the size
- of the structure, adding to the end.</p>
+ <span class="main-name">ncurses</span> 6.3 release.</p>
- <p>Existing applications which were linked to the
- <span class="part-name">ncurses 6.0</span> high-level
- (<em>ncurses</em>, <em>ncursesw</em>) and low-level
- (<em>tinfo</em>, <em>tinfo</em>) libraries should not require
- re-linking since the binary interface did not change, nor did
- the structure offsets with <code>TERMINAL</code> change.</p>
-
- <p>A few applications use the inner <code>TERMTYPE</code>
- structure's offsets to refer to terminfo capabilities within
- that structure. Again, those do not require modification
- because their offsets within <code>TERMINAL</code> did not
- change.</p>
- </li>
-
- <li>
- <p>When configured for wide-characters, i.e.,
- “ncursesw” the <code>TERMINAL</code> structure is
- extended.</p>
-
- <p>The new data in <code>TERMINAL</code> holds the same
- information as <code>TERMTYPE</code>, but with larger numbers
- (“int” versus “short”). It is named
- <code>TERMTYPE2</code>.</p>
-
- <p>The library uses this structure internally in preference
- to <code>TERMTYPE</code>, referring to <code>TERMTYPE</code>
- only to initialize it for applications that use the
- capabilities defined in <code><term.h></code></p>
- </li>
-
- <li>
- <p>When configured for 8-bit (narrow) characters, the
- <code>TERMTYPE2</code> structure is not used.</p>
- </li>
-
- <li>The updated application binary interface is 6.1.20171230
- (used for new <a href=
- "https://invisible-island.net/ncurses/ncurses-mapsyms.html">versioned
- symbols</a>), although the interface changes were developed
- several months previously.</li>
- </ul>
-
- <p>The motivation for making this extension came from noticing
- that <a href=
- "https://invisible-island.net/ncurses/tctest.html#bsd42-numeric-caps">
- termcap applications</a> could (though not <a href=
- "https://invisible-island.net/ncurses/ncurses-slang.html#cause_numbers">
- realistically</a>) use larger numbers than would fit in 16-bits,
- and the fact that the number of color pairs for a 256-color xterm
- could not be expressed in terminfo (i.e., 32767 versus 65536).
- Also, a few terminals support direct-colors, which could use the
- extension.</p>
-
- <p>Generally speaking, applications that use internal details of
- a library are unsupported. There was exactly one exception for
- <span class="main-name">ncurses</span>: the <span class=
- "main-name">tack</span> program <em>used</em> the internal
- details of <code>TERMINAL</code>, because it provides an
- ncurses-specific feature for interactively modifying a terminfo
- description and writing the updated description to a text-file.
- It was possible to not only separate <span class=
- "main-name">tack</span> from these <a href=
- "https://invisible-island.net/ncurses/tack.html#portable">internal
- details of <span class="main-name">ncurses</span></a>, but to
- generalize it so that the program works with Unix curses
- (omitting the ncurses-specific feature). That was released as
- <a href=
- "https://invisible-island.net/ncurses/tack/CHANGES.html#index-t20170726">
- <span class="main-name">tack</span> 1.08</a> in July
- 2017.</p>
-
- <p>While making changes to <span class="main-name">tack</span> to
- eliminate its dependency upon <span class=
- "main-name">ncurses</span> internals, the publicly-visible
- details of those internals were reviewed, and some symbols were
- moved to private header files, while others were marked
- explicitly as <span class="main-name">ncurses</span> internals.
- Future releases of <span class="main-name">ncurses</span> may
- eliminate some of those symbols (such as those used by
- <span class="main-name">tack</span> 1.07) because they are
- neither part of the API or the ABI.</p>
-
- <p>Using the <code>TERMTYPE2</code> extended numeric
- capabilities, it is possible to support both color pair values
- and color values past 32767. Taking compatibility into account,
- developers readily understand that neither function signatures
- nor structure offsets change. Also, existing functions have to
- operate with the extended numbers. Most of that work is internal
- to the library. For the external interfaces, a hybrid approach
- was used:</p>
-
- <ul>
- <li>
- <p>X/Open Curses defined function prototypes such as
- <code>wattr_set</code> with an unused parameter, for
- “future” use. After 25 years, the future is here:
- <span class="main-name">ncurses</span> uses the parameter to
- augment color pair values as described in the <a href=
- "https://invisible-island.net/ncurses/man/curs_attr.3x.html#h2-EXTENSIONS">
- manual page</a>.</p>
- </li>
-
- <li>
- <p>Other functions such as those defining color pairs did not
- have a corresponding <em>reserved</em> parameter. For those,
- <span class="main-name">ncurses</span> defines extended
- versions such as <code>init_extended_pair</code> (versus
- <code>init_pair</code>), <code>init_extended_color</code>
- (versus <code>init_color</code>).</p>
- </li>
- </ul>
-
- <p>Additionally, to improve performance other changes (and
- extensions) are provided in this release:</p>
-
- <ul>
- <li>
- <p>Several new functions simplify management of large sets of
- color pairs: <code>reset_color_pairs</code>,
- <code>alloc_pair</code>, <code>find_pair</code> and
- <code>free_pair</code>.</p>
- </li>
-
- <li>
- <p>New "RGB" extension capability for direct-color support is
- used to improve performance of
- <code>color_content</code>.</p>
- </li>
-
- <li>
- <p>The internal <code>colorpair_t</code> is now a struct,
- eliminating an internal 8-bit limit on colors</p>
- </li>
+ <h3><a name="h3-library" id="h3-library">Library improvements</a></h3>
- <li>
- <p>Allocation for <code>SCREEN</code>'s color-pair table
- starts small, grows on demand up to the limit given in the
- terminal description.</p>
- </li>
+ <h4><a name="h4-new-library" id="h4-new-library">New features</a></h4>
- <li>
- <p><code>setcchar</code> and <code>getcchar</code> now treat
- a negative color-pair as an error.</p>
- </li>
- </ul>
+ <p>There are no new features in this release.</p>
<h4><a name="h4-fixes-library" id="h4-fixes-library">Other
improvements</a></h4>
- <p>These are new or revised features:</p>
-
- <ul>
- <li>
- <p>modify <code>c++/etip.h.in</code> to accommodate
- deprecation of throw and throws in c++17</p>
- </li>
-
- <li>
- <p>add new function <code>unfocus_current_field</code></p>
- </li>
-
- <li>
- <p>add option to preserve leading whitespace in form
- fields</p>
- </li>
-
- <li>
- <p>add a macro for <code>is_linetouched</code> and adjust the
- function's return value to make it possible for most
- applications to check for an error-return.</p>
- </li>
-
- <li>
- <p>add build-time utility <code>report_offsets</code> to help
- show when the various configurations of tinfo library are
- compatible or not.</p>
- </li>
- </ul>
-
- <p>These were done to limit or ultimately deprecate features:</p>
-
- <ul>
- <li>
- <p>drop two symbols obsoleted in 2004:
- <code>_nc_check_termtype</code>, and
- <code>_nc_resolve_uses</code></p>
- </li>
-
- <li>
- <p>move <code>_nc_tracebits</code>, <code>_tracedump</code>
- and <code>_tracemouse</code> to <code>curses.priv.h</code>,
- since they are not part of the suggested ABI6.</p>
- </li>
-
- <li>
- <p>mark some structs in form/menu/panel libraries as
- potentially opaque without modifying API/ABI.</p>
- </li>
-
- <li>
- <p>ifdef'd header-file definition of <code>mouse_trafo</code>
- with <code>NCURSES_NOMACROS</code></p>
- </li>
-
- <li>
- <p>remove initialization-check for calling <code>napms</code>
- in the term-driver configuration; none is needed.</p>
- </li>
-
- <li>
- <p>modify <code>trace</code> to avoid overwriting existing
- file</p>
- </li>
- </ul>
-
<p>These are improvements to existing features:</p>
<ul>
<li>
- <p>modify <code>make_hash</code> to allow building with
- address-sanitizer, assuming that <code>--disable-leaks</code>
- is configured.</p>
+ <p>modify <tt>delscreen</tt> to more effectively delete all
+ windows on the given screen.</p>
</li>
<li>
- <p>move <code>SCREEN</code> field for <code>use_tioctl</code>
- data before the ncursesw fields, and limit that to the
- sp-funcs configuration to improve termlib compatibility</p>
+ <p>modify <tt>wnoutrefresh</tt> to call <tt>pnoutrefresh</tt>
+ if its parameter is a pad, rather than treating it as an
+ error, and modify new_panel to permit its window-parameter to
+ be a pad</p>
</li>
<li>
- <p>modify db-iterator:</p>
-
- <ul>
- <li>
- <p>ignore zero-length files in db-iterator; these are
- useful for instance to suppress
- <code>$HOME/.terminfo</code> when not wanted.</p>
- </li>
-
- <li>
- <p>modify <code>update_getenv</code> to ensure that
- environment variables which are not initially set will be
- checked later if an application happens to set them</p>
- </li>
- </ul>
+ <p>modify curses_trace() to show the trace-mask as symbols,
+ e.g., <tt>TRACE_ORDINARY</tt>, <tt>DEBUG_LEVEL(3)</tt>.</p>
</li>
<li>
- <p>modify <code>_nc_outc_wrapper</code> to use the standard
- output if the screen was not initialized, rather than
- returning an error.</p>
+ <p>improve checks for valid mouse events when an intermediate
+ mouse state is not part of the mousemask specified by the
+ caller</p>
</li>
<li>
- <p>improve checks for low-level terminfo functions when the
- terminal has not been initialized.</p>
+ <p>allow extended-color number in <em>opts</em> parameter of
+ <tt>wattr_on</tt>.</p>
</li>
<li>
- <p>modify <code>set_curterm</code> to update
- <code>ttytype[]</code> data used by longname/p></p>
+ <p>improve <tt>_tracecchar_t2</tt> formatting of
+ base+combining character.</p>
</li>
<li>
- <p>modify <code>_nc_get_screensize</code> to allow for
- <code>use_env</code> and <code>use_tioctl</code> state to be
- per-screen when sp-funcs are configured, better matching the
- behavior when using the term-driver configuration.</p>
+ <p>trim out some unwanted linker options from ncurses*config
+ and .pc files seen in Fedora 36+.</p>
</li>
<li>
- <p>remove an early-return from <code>_nc_do_color,</code>
- which can interfere with data needed by <code>bkgd</code>
- when <span class="main-name">ncurses</span> is configured
- with extended colors</p>
+ <p>improve shell-scripts with <em>shellcheck</em></p>
</li>
<li>
- <p>incorporate <code>A_COLOR</code> mask into
- <code>COLOR_PAIR</code>, in case user application provides an
- out-of-range pair number</p>
+ <p>improve use of "trap" in shell scripts, using a
+ script.</p>
</li>
<li>
- <p>modify logic for <code>endwin</code>-state to be able to
- detect the case where the screen was never initialized, using
- that to trigger a flush of <span class=
- "main-name">ncurses'</span> buffer for <code>mvcur</code>,
- e.g., in the sample program <span class=
- "part-name">dots_mvcur</span> for the term-driver
- configuration.</p>
+ <p>modify <tt>make-tar.sh</tt> scripts to make timestamps
+ more predictable.</p>
</li>
</ul>
<ul>
<li>
- <p>fixes for writing extended color pairs in
- <code>putwin</code>.</p>
- </li>
-
- <li>
- <p>modify no-leaks code for <code>lib_cur_term.c</code> to
- account for the <code>tgetent</code> cache.</p>
- </li>
-
- <li>
- <p>amend handling of the <code>repeat_char</code> capability
- in <code>EmitRange</code> to avoid scope creep: translate the
- character to the alternate character set when the alternate
- character set is enabled, and do not use
- <code>repeat_char</code> for characters past 255.</p>
- </li>
-
- <li>
- <p>improve wide-character implementation of
- <code>myADDNSTR</code> in <code>frm_driver.c</code>, which
- was inconsistent with the normal implementation.</p>
- </li>
-
- <li>
- <p>modify <code>winnstr</code> and <code>winchnstr</code> to
- return error if the output pointer is null, as well as adding
- a null pointer check of the window pointer for better
- compatibility with other implementations.</p>
- </li>
-
- <li>
- <p>modify <code>setupterm</code> to save original tty-modes
- so that <code>erasechar</code> works as expected. Also modify
- <code>_nc_setupscreen</code> to avoid redundant calls to get
- original tty-modes.</p>
- </li>
-
- <li>
- <p>modify <code>wattr_set</code> and <code>wattr_get</code>
- to return <code>ERR</code> if <em>win</em>-parameter is null,
- as documented.</p>
- </li>
-
- <li>
- <p>correct order of initialization for traces in
- <code>use_env</code> and <code>use_tioctl</code> versus first
- <code>_tracef</code> calls.</p>
- </li>
-
- <li>
- <p>correct parameters for <code>copywin</code> call in
- <code>_nc_Synchronize_Attributes</code></p>
- </li>
-
- <li>
- <p>flush the standard output in <code>_nc_flush</code> for
- the case where <code>SP</code> is zero, e.g., when called via
- <code>putp</code>. This fixes a scenario where
- “tput flash” did not work after changes in
- 20130112.</p>
- </li>
-
- <li>
- <p>amend internal use of <code>tputs</code> to consistently
- use the number of lines affected, e.g., for insert/delete
- character operations. While merging terminfo source early in
- 1995, several descriptions used the
- “<code>*</code>” proportional delay for these
- operations, prompting a change in <code>doupdate</code>.</p>
- </li>
-
- <li>
- <p>correct return-value of extended <code>putwin</code>.</p>
- </li>
-
- <li>
- <p>double-width multibyte characters were not counted
- properly in <code>winsnstr</code> and
- <code>wins_nwstr</code>.</p>
- </li>
-
- <li>
- <p>amend fix for <code>_nc_ripoffline</code> from 20091031 to
- make <code>test/ditto.c</code> work in threaded
- configuration.</p>
- </li>
-
- <li>
- <p>modify <code>_nc_viscbuf2</code> and
- <code>_tracecchar_t2</code> to trace wide-characters as a
- whole rather than their multibyte equivalents.</p>
- </li>
-
- <li>
- <p>minor fix in <code>wadd_wchnstr</code> to ensure that each
- cell has nonzero width.</p>
+ <p>modify <tt>misc/gen-pkgconfig.in</tt> to allow for the
+ case where the library directory does not yet exist, since
+ this is processed before doing an install</p>
</li>
<li>
- <p>move <code>PUTC_INIT</code> calls next to
- <code>wcrtomb</code> calls, to avoid carry-over of error
- status when processing Unicode values which are not
- mapped.</p>
+ <p>set trailing null on string passed from <tt>winsnstr</tt>
+ to <tt>wins_nwstr</tt>.</p>
</li>
<li>
- <p>add missing assignment in <code>lib_getch.c</code> to make
- <code>notimeout</code> work</p>
+ <p>modify <tt>waddch_literal</tt> to allow for double-width
+ base character when merging a combining character</p>
</li>
</ul>
<h3><a name="h3-programs" id="h3-programs">Program
improvements</a></h3>
- <p>While reviewing user feedback, it became apparent that the
- differences between <a href=
- "https://invisible-island.net/ncurses/man/tset.1.html#h3-reset---reinitialization">
- <span class="part-name">reset</span></a> (an alias for
- <span class="part-name">tset</span>) and “<span class=
- "part-name">tput reset</span>” were confusing:</p>
-
- <ul>
- <li>one (<a href=
- "https://invisible-island.net/ncurses/man/tset.1.html">tset</a>)
- updated the terminal modes, but used only part of the terminfo
- capabilities for initialization, while</li>
-
- <li>the other (<a href=
- "https://invisible-island.net/ncurses/man/tput.1.html"><span class="part-name">tput</span></a>)
- used all of the terminal capabilities while neglecting the
- terminal modes.</li>
- </ul>
-
- <p>On further investigation, it turned out that the differences
- were largely an accident due to the way those programs had
- evolved.</p>
-
- <p>This release eliminates the unnecessary differences, using the
- same approach for <span class="part-name">tput</span>'s
- <em>init</em> (initialization), <em>reset</em> and <em>clear</em>
- operations as the separate <a href=
- "https://invisible-island.net/ncurses/man/tset.1.html#h3-reset---reinitialization">
- reset</a> and <a href=
- "https://invisible-island.net/ncurses/man/clear.1.html"><span class="part-name">
- clear</span></a> programs. Doing this does not change the
- command-line options; existing scripts are unaffected.</p>
-
- <p>These are the user-visible changes for the three programs
- (<span class="part-name">tput</span>, <span class=
- "part-name">tset</span> and <span class=
- "part-name">clear</span>):</p>
-
- <ul>
- <li>
- <p>add the terminal-mode parts of “<span class=
- "part-name">reset</span>” (aka <span class=
- "part-name">tset</span>) to the “<code>tput
- reset</code>” command, making the two almost the same
- except for window-size.</p>
- </li>
-
- <li>
- <p>improve <span class="part-name">tput</span>'s check for
- being called as “init” or “reset” to
- allow for transformed names.</p>
- </li>
-
- <li>
- <p>add “clear” as a possible link/alias to
- <span class="part-name">tput</span>.</p>
- </li>
-
- <li>
- <p>amend changes for <span class="part-name">tput</span> to
- reset tty modes to “sane” if the program is run
- as “reset”, like <span class=
- "part-name">tset</span>. Likewise, ensure that <span class=
- "part-name">tset</span> sends either reset- or
- init-strings.</p>
- </li>
-
- <li>
- <p>add <code>-x</code> option to <span class=
- "part-name">clear</span>/<span class="part-name">tput</span>
- to make the <code>E3</code> extension optional</p>
- </li>
-
- <li>
- <p>add functionality of
- “<code>tset -w</code>” to <span class=
- "part-name">tput</span>, like the
- “<code>-c</code>” feature this is not optional in
- <span class="part-name">tput</span>.</p>
- </li>
-
- <li>
- <p>add options <code>-T</code> and <code>-V</code> to
- <span class="part-name">clear</span> command for
- compatibility with <span class="part-name">tput</span>.</p>
- </li>
-
- <li>
- <p>drop long-obsolete “<code>-n</code>” option
- from <span class="part-name">tset</span>.</p>
- </li>
-
- <li>
- <p>modify <span class="part-name">tset</span>'s assignment to
- <code>TERM</code> in its output to reflect the name by which
- the terminal description is found, rather than the primary
- name. That was an unnecessary part from the initial
- conversion of <span class="part-name">tset</span> from
- termcap to terminfo. The termcap library in 4.3BSD did this
- to avoid using the short 2-character name</p>
- </li>
-
- <li>
- <p>remove a restriction in <span class=
- "part-name">tput</span>'s support for termcap names which
- omitted capabilities normally not shown in termcap
- translations</p>
- </li>
-
- <li>
- <p>add usage message to <span class="part-name">clear</span>
- command</p>
- </li>
-
- <li>
- <p>improve usage messages for <span class=
- "part-name">tset</span> and <span class=
- "part-name">tput</span>.</p>
- </li>
- </ul>
-
- <p>Other user-visible improvements and new features include:</p>
-
- <ul>
- <li>
- <p>modify <span class="part-name">tic</span>/<span class=

-
- <p>Several of the less apparent features deal with translation of

- by <span class="part-name">tic</span>:</p>
-
- <ul>
- <li>
- <p>modify check in <code>fmt_entry</code> to handle a

- </li>
-
- <li>
- <p>correct read of terminfo entry in which all strings are
- absent or explicitly cancelled. Before this fix, the result
- was that all were treated as only absent.</p>
- </li>
-
- <li>
- <p>modify <span class="part-name">infocmp</span> to suppress
- mixture of absent/cancelled capabilities that would only show
- as “<code>NULL, NULL</code>”, unless the

- </li>

- for reporting inconsistencies between the expected number of
- parameters for a capability and the actual.</p>
- </li>
-
- <li>
- <p>remove <span class="part-name">tic</span> warning about
- “<code>^?</code>” in string capabilities, which
- was marked as an extension; however all Unix implementations
- support this and X/Open Curses does not address it. On the
- other hand, <a href=
- "https://invisible-island.net/ncurses/tctest.html#bsd42-ctl-question">
- BSD termcap</a> did not support this feature (until the
- <a href=

- mid-1990s</a>).</p>
-
- <p>in <code>_nc_infotocap</code>, added a check to ensure

- termcap.</p>
- </li>
-
- <li>
- <p>modify <code>sscanf</code> calls in
- <code>_nc_infotocap</code> for patterns
- “<code>%{number}%+%c</code>” and

- termcap.</p>
- </li>
-
- <li>
- <p>in <code>_nc_tic_expand</code> and
- <code>_nc_infotocap</code>, improved string-length check when

- “<code>\xxx</code>” format for control
- characters, to make the output of <span class=
- "part-name">tic</span>/<span class="part-name">infocmp</span>
- more predictable.</p>
- </li>
-
- <li>
- <p>limited termcap “<code>%d</code>” width to 2
- digits on input, and use “<code>%2</code>” in
- preference to “<code>%02</code>” on output.</p>

-
- <li>
- <p>correct terminfo/termcap conversion of

-
- <h4><a name="h4-examples" id="h4-examples">Examples</a></h4>
-
- <p>Along with the library and utilities, many improvements were
- made to the <a href=
- "https://invisible-island.net/ncurses/ncurses-examples.html">ncurses-examples</a>.</p>
-
- <p>These changes were made to demonstrate new extensions in
- <span class="main-name">ncurses</span>:</p>
-
- <ul>
- <li>
- <p>add <span class="part-name">demo_new_pair</span> program,
- to demonstrate <a href=
- "https://invisible-island.net/ncurses/man/new_pair.3x.html#h3-alloc_pair">
- <code>alloc_pair</code></a>, <a href=
- "https://invisible-island.net/ncurses/man/new_pair.3x.html#h3-find_pair">
- <code>find_pair</code></a> and <a href=
- "https://invisible-island.net/ncurses/man/new_pair.3x.html#h3-free_pair">
- <code>free_pair</code></a> functions.</p>
-
- <p>This program iterates over the possible color
- combinations, allocating or initializing color pairs. For
- best results, choose screen-width dividing evenly into the
- number of colors. e.g.,</p>
-
- <blockquote>
- <table summary="sample layouts for demo_new_pair">
- <tr>
- <td><code>32x64,32x128</code> </td>
-
- <td>256 colors</td>
- </tr>
-
- <tr>
- <td><code>24x44,24x88</code></td>
-
- <td>88 colors</td>
- </tr>
-
- <tr>
- <td><code>32x64,24x128</code></td>
-
- <td>16 colors</td>
- </tr>
- </table>
- </blockquote>
- </li>
-
- <li>
- <p>add <span class="part-name">extended_color</span> program,
- like the older <span class="part-name">color_set</span>
- program, but using the extended color functions, with and
- without the SP-functions interface.</p>
- </li>
-
- <li>
- <p>add <span class="part-name">picsmap</span> program to fill
- in some testing issues not met by <span class=
- "part-name">dots</span>, using this as the third example in a
- comparison of the <a href=
- "https://invisible-island.net/ncurses/ncurses-slang.html#compare_picsmap">
- ncurses versus slang</a> libraries.</p>
-
- <p>The program can directly read X bitmap and pixmap files,
- displaying a picture. It can read other image files using
- <span class="part-name">ImageMagick</span>'s <span class=
- "part-name">convert</span> program to translate the image
- into text.</p>
-
- <p>For 16-, 88- and 256-color terminal descriptions,
- <span class="part-name">picsmap</span> can load a palette
- file which tells it which color palette entries to use. For
- direct-colors, the terminal descriptions use the
- <code>RGB</code> extension capability.</p>
- </li>
- </ul>
-
- <p>There are other new example programs and a few scripts:</p>
-
- <ul>
- <li>
- <p>add <span class="part-name">dots_xcurses</span> program to
- illustrate a different approach used for extended colors
- which can be contrasted with <span class=
- "part-name">dots_curses</span>.</p>
- </li>
-
- <li>
- <p>add <span class="part-name">list_keys</span> program show
- function keys for one or more terminal descriptions. It uses
- <span class="main-name">ncurses'</span>s convention of
- modifiers for special keys, based on xterm.</p>
- </li>
-
- <li>
- <p>add <span class="part-name">padview</span> program, to
- compare pads with direct updates in the <span class=
- "part-name">view</span> program.</p>
- </li>
-
- <li>
- <p>add <span class="part-name">sp_tinfo</span> program to
- exercise the SP-functions extension of the low-level terminfo
- library.</p>
- </li>
-
- <li>
- <p>add test-programs for <code>termattrs</code> and
- <code>term_attrs</code> functions.</p>
- </li>
-
- <li>
- <p>add <span class="part-name">test_sgr</span> program to
- exercise all combinations of the sgr capability.</p>
- </li>
-
- <li>
- <p>add <span class="part-name">tput-colorcube</span> demo
- script, imitating xterm's 88- and 256-color scripts using
- <span class="part-name">tput</span>.</p>
- </li>
-
- <li>
- <p>add <span class="part-name">tput-initc</span> script to
- demonstrate how <span class="part-name">tput</span> may be
- used to initialize a color palette from a data file.</p>
- </li>
- </ul>
-
- <p>A variety of improvements were made to existing programs, both
- new features as well as options added to make the set of programs
- more consistent.</p>
-
- <p>The <span class="part-name">ncurses</span> program is the
- largest; a proportionately large number of changes were made to
- it:</p>
+ <p>Along with the library and utilities, improvements were made
+ to the <a href=
+ "@HOMEPAGE@/ncurses-examples.html">ncurses-examples</a>. Most of
+ this activity aimed at improving the test-packages:</p>
<ul>
<li>
- <p>modify a/A screens to make exiting on an escape character
- depend on the start of keypad and timeout modes, to allow
- better testing of function-keys.</p>
-
- <p>add “<code>t</code>” toggle for
- <code>notimeout</code> function.</p>
- </li>
-
- <li>
- <p>modify layout of b/B screens to allow for additional
- annotation on the right margin; some terminals with partial
- support did not display well.</p>
- </li>
-
- <li>
- <p>modify c/C screens to allow for extended color pairs.</p>
-
- <p>add z/Z <em>zoom</em> feature to make extended color pairs
- easier to test.</p>
-
- <p>modify test-screens to take advantage of wide screens,
- reducing the number of lines used for 88- and 256-colors.</p>
- </li>
-
- <li>
- <p>modify “<code>d</code>” edit-color screen to
- optionally read xterm color palette directly from terminal,
- as well as handling <code>KEY_RESIZE</code> and
- screen-repainting with control/L and control/R.</p>
- </li>
-
- <li>
- <p>add examples to “<code>F</code>” screen for
- <code>WACS_D_PLUS</code> and <code>WACS_T_PLUS</code>.</p>
- </li>
-
- <li>
- <p>improve “<code>g</code>” screen, correcting
- ifdef which made the legend not reflect changes to keypad-
- and scroll-modes. Added check for return-value of
- <code>putwin</code>.</p>
- </li>
-
- <li>
- <p>make “<code>s</code>” test easier to
- understand which subtests are available</p>
-
- <p>add a corresponding “<code>S</code>”
- wide-character overlap test-screen.</p>
- </li>
-
- <li>
- <p>add “<code>v</code>” screen to show
- <code>baudrate</code> and other values.</p>
- </li>
- </ul>
-
- <p>These changes were made to the other examples:</p>
-
- <ul>
- <li>
- <p>modify <span class="part-name">blue</span> program to use
- Unicode values for card-glyphs when available, as well as
- improving the check for CP437 and CP850.</p>
- </li>
-
- <li>
- <p>improve <span class="part-name">demo_menus</span> program,
- allowing mouse-click on the menu-headers to switch the active
- menu. This requires a new extension option
- <code>O_MOUSE_MENU</code> to tell the menu driver to put
- mouse events which do not apply to the active menu back into
- the queue so that the application can handle the event.</p>
- </li>
-
- <li>
- <p>correct logic in <span class=
- "part-name">demo_terminfo</span> program for
- “<code>-f</code>” option</p>
- </li>
-
- <li>
- <p>modify <span class="part-name">ditto</span> program to
- allow <code>$XTERM_PROG</code> environment variable to
- override "xterm" as the name of the program to run in the
- threaded configuration.</p>
- </li>
-
- <li>
- <p>add several options to the “<em>dots</em>”
- test-programs.</p>
- </li>
-
- <li>
- <p>modify <span class="part-name">filter</span> program:</p>
-
- <ul>
- <li>illustrate an alternative to <code>getnstr</code>, that
- polls for input while updating a clock on the right margin
- as well as responding to window size-changes.</li>
-
- <li>adapt logic used in <a href=
- "https://invisible-island.net/dialog/"><span class=
- "main-name">dialog</span></a> <a href=
- "https://invisible-island.net/dialog/manpage/dialog.html#h3-Common-Options">
- “<code>--keep-tite</code>” option</a> for
- <span class="part-name">filter</span> program as the "-a"
- option. When set, <span class="part-name">filter</span>
- attempts to suppress the alternate screen.</li>
- </ul>
- </li>
-
- <li>
- <p>modify <span class="part-name">knight</span> program to
- provide the "slow" solution for small screens using
- “<code>R</code>”, noting that Warnsdorf's method
- is easily done with “<code>a</code>”.</p>
- </li>
-
- <li>
- <p>modify the <span class="part-name">savescreen</span>
- program to add test patterns that exercise 88-, 256-, etc.,
- colors.</p>
- </li>
-
- <li>
- <p>add options to <span class="part-name">test_arrays</span>,
- for selecting termcap vs terminfo, etc.</p>
- </li>
-
- <li>
- <p>modify the <span class="part-name">view</span>
- program:</p>
-
- <ul>
- <li>expand tabs using the ncurses library rather than in
- the test-program.</li>
-
- <li>eliminate the “<code>-n</code>” option by
- simply reading the whole file.</li>
-
- <li>implement page up/down commands.</li>
-
- <li>remove the very old <code>SIGWINCH</code> example; just
- use <code>KEY_RESIZE</code>.</li>
- </ul>
- </li>
-
- <li>
- <p>improve animation in <span class="part-name">xmas</span>
- program by adding a time-delay in <code>blinkit</code>.</p>
- </li>
-
- <li>
- <p>modify several test-programs which call
- <code>use_default_colors</code> to consistently do this only
- if the “<code>-d</code>” option is given.</p>
- </li>
-
- <li>
- <p>modify the install-rule for ncurses-examples to put the
- data files in the data directory, e.g.,
- <code>/usr/share/ncurses-examples</code>.</p>
- </li>
-
- <li>

- <h3><a name="h3-database" id="h3-database">Terminal
- database</a></h3>
-
- <p>There are several new terminal descriptions:</p>
-
- <blockquote>
- <p><code>dumb-emacs-ansi</code>, <code>dvtm</code>,
- <code>dvtm-256color</code>, <code>fbterm</code>,
- <code>iterm2</code>, <code>linux-m1</code> <em>minitel

-
- <p><code>xterm+noalt</code>, <code>xterm+titlestack</code>,
- <code>xterm+alt1049</code>, <code>xterm+alt+title</code>
- <em>building blocks</em> and <code>xterm+direct</code>,

- patch #331</a>.</p>
-
- <p>several other “<code>-direct</code>”
- descriptions to address the differences of other terminal
- emulators versus <code>xterm-direct</code>.</p>
- </blockquote>
-
- <p>There are many changes to existing terminal descriptions. Some
- were updates to several descriptions:</p>
-
- <ul>
- <li>use <code>xterm+sm+1006</code> in several terminal
- descriptions which were validated as supporting the extended
- mouse feature for their respective terminal emulators.</li>
-
- <li>corrected <em>sgr</em>/<em>sgr0</em> strings in a few cases
- reported by <span class="part-name">tic</span>, making those
- correspond to the non-<em>sgr</em> settings where they differ,
- but otherwise use ECMA-48 consistently.</li>
-
- <li>add 0.1sec mandatory delay to <em>flash</em> capabilities
- using the VT100 reverse-video control</li>
- </ul>
-
- <p>while others affected specific descriptions. These were
- retested, to take into account new/undocumented changes by their
- developers:</p>
-
- <blockquote>
- <p><code>iterm</code>, <code>minitel</code>, <code>st</code>,
- <code>viewdata</code>, <code>nsterm</code></p>
- </blockquote>
-
- <p>while these are specific fixes based on user reports, or

</li>
- </ul>
- <p>Some of the improvements are more subtle, relating to the way
- the information is presented:</p>
-
- <ul>
<li>
- <p>Made minor fixes to manpage <em>NAME/SYNOPSIS</em>
- sections to consistently use rule that either all functions
- which are prototyped in <em>SYNOPSIS</em> are listed in the
- <em>NAME</em> section, or the manual-page name is the sole
- item listed in the <em>NAME</em> section. The latter is used
- to reduce clutter, e.g., for the top-level library manual
- pages as well as for certain feature-pages such as <a href=
- "https://invisible-island.net/ncurses/man/curs_sp_funcs.3x.html">
- <em>SP-funcs</em></a> and <a href=
- "https://invisible-island.net/ncurses/man/curs_threads.3x.html">

</li>
<li>
- <p>improve manual pages for utilities with respect to POSIX
- versus X/Open Curses.</p>
+ <p>add <tt>setlocale</tt> call to several test-programs.</p>
</li>
<li>
- <p>improve organization of the <a href=
- "https://invisible-island.net/ncurses/man/curs_attr.3x.html"><em>
- attributes</em></a> and <a href=
- "/ncurses/man/curs_color.3x.html"><em>color</em></a> manual
- pages.</p>
+ <p>workaround in <tt>test/picsmap.c</tt> for use of floating
+ point for rgb values by ImageMagick 6.9.11, which appears to
+ use the wrong upper limit.</p>
</li>
- </ul>
-
- <h3><a name="h3-bug-fixes" id="h3-bug-fixes">Interesting
- bug-fixes</a></h3>
- <ul>
<li>
- <p>modify <span class="part-name">toe</span> to not exit if
- unable to read a terminal description, e.g., if there is a
- permission problem.</p>
+ <p>use static libraries for AdaCurses test-package for
+ Mageia, since no gprbuild package is available.</p>
</li>
<li>
- <p>correct 20100515 change for weak signals versus
- sigprocmask</p>
+ <p>install Ada95 sample programs in libexecdir, adding a
+ wrapper script to invoke those.</p>
</li>
- <li>work around Ada tool-breakage in Debian 9 and later by
- invoking <code>gprconfig</code> to specify the C compiler to be
- used by <code>gnatmake</code>, and conditionally suppressing
- <code>Library_Options</code> line for static libraries.</li>
-
<li>
- <p>There were, as well, several bug-fixes to handle illegal
- input for <span class="part-name">tic</span>. Because those
- did not correspond to useful terminal descriptions, most
- users are unaffected.</p>
+ <p>install ncurses-examples programs in libexecdir, adding a
+ wrapper script to invoke those.</p>
</li>
</ul>

- library.</p>
- </li>
+ <dt><span class="part-name"><em>test/test_delwin</em></span>
+ </dt>
- <li>
- <p>A few software packagers use a configuration option of
- <span class="main-name">ncurses</span> which allows the
- low-level <em>tinfo</em> library to be shared between the
- high-level <em>ncurses</em> and <em>ncursesw</em> libraries.
- This new feature was designed to work in that configuration
- as well.</p>
- </li>
- </ul>
+ <dd>demonstrate deleting a window</dd>
- <p>Other applications (i.e., using the 8-bit <em>ncurses</em>
- library) which read the extended terminal descriptions see those

- <p>These changes provide support for <span class=

- "https://invisible-island.net/ncurses/tack/CHANGES.html#index-t20170726">
- July 2017</a>:</p>
+ <p>There are several new terminal descriptions:</p>
<ul>
- <li>
- <p>add <code>--without-tack</code> configure option to refine
- <code>--with-progs</code> configure option. Normally
- <span class="main-name">tack</span> is built outside the
- <span class="main-name">ncurses</span> tree, but a few
- packagers combine it during the build. If
- <code>term_entry.h</code> is installed, there is no advantage
- to in-tree builds.</p>
+ <li><tt><a href=
+ "@HOMEPAGE@/terminfo.src.html#tic-mosh">mosh</a></tt>
</li>
- <li>
- <p>adjust configure-script to define
- <code>HAVE_CURSES_DATA_BOOLNAMES</code> symbol needed for
- <span class="main-name">tack</span> 1.08 when built in-tree.
- Rather than relying upon internal "_nc_" functions,
- <span class="main-name">tack</span> now uses the boolean,
- number and string capability name-arrays provided by
- <span class="main-name">ncurses</span> and SVr4 Unix curses.
- It still uses <code>term_entry.h</code> for the definitions
- of the extended capability arrays.</p>
+ <li><tt><a href=
+ "@HOMEPAGE@/terminfo.src.html#tic-mosh-256color">mosh-256color</a></tt>
</li>
- <li>
- <p>add dependency upon ncurses_cfg.h to <span class=
- "part-name">tic</span>'s header-files; any program using
- <span class="part-name">tic</span>-library will have to
- supply this file. Legacy <span class="main-name">tack</span>
- versions supply this file; ongoing <span class=
- "main-name">tack</span> development has dropped the
- dependency upon <span class="part-name">tic</span>-library

- </ul>
-
- <p>Other changes to the configure-script and generated files
- include</p>
- <ul>
- <li>
- <p>add configure options to disable checks for form, menu and
- panel libraries so that ncurses-examples can be built with
- non-SVr4 curses implementations.</p>
+ <li><tt><a href=
+ "@HOMEPAGE@/terminfo.src.html#tic-teken-sc">teken-sc</a></tt>

+ <li><tt><a href=
+ "@HOMEPAGE@/terminfo.src.html#tic-teken-vt">teken-vt</a></tt>
</li>
- <li>
- <p>add configure option <code>--disable-wattr-macros</code>
- for use in cases where one wants to use the same headers for
- ncurses5/ncurses6 development, by suppressing the
- <em>wattr*</em> macros which differ due to the introduction
- of extended colors</p>
+ <li><tt><a href=
+ "@HOMEPAGE@/terminfo.src.html#tic-xgterm">xgterm</a></tt>
</li>
+ </ul>
- <li>
- <p>modify configure macro for shared-library rules to use
- <code>-Wl,-rpath</code> rather than <code>-rpath</code> to
- work around a bug in <span class="part-name">scons</span></p>
- </li>
+ <p>There are many changes to existing terminal descriptions. Some
+ were updates to several descriptions:</p>
+ <ul>
<li>
- <p>improve ncurses-examples' configure script to define as
- needed <code>NCURSES_WIDECHAR</code> for platforms where
- <code>_XOPEN_SOURCE_EXTENDED</code> does not work. Also
- modified the test program to ensure that if building with
- <span class="main-name">ncurses</span>, that the
- <code>cchar_t</code> type is checked, since that is normally
- (since <a href=
- "https://invisible-island.net/ncurses/NEWS.html#t20111030">20111030</a>)
- ifdef'd depending on this test.</p>
+ <p>make description-fields distinct</p>
</li>
<li>
- <p>modify configure script to handle the case where
- <span class="part-name">tic</span>-library is renamed, but
- the <code>--with-debug</code> option is used by itself
- without normal or shared libraries</p>
+ <p>fix errata in description fields</p>
</li>
<li>
- <p>modify editing script which generates resulting.map to
- work with the clang configuration on recent FreeBSD, which
- gives an error on an empty "local" section.</p>
- </li>
+ <p>add/use several building-blocks:</p>
- <li>
- <p>improve configure check for setting the
- <code>WILDCARD_SYMS</code> variable; on ppc64 the variable is
- in the <strong><em>Data</em></strong> section rather than
- <strong><em>Text</em></strong>.</p>
- </li>
+ <ul>
+ <li><a href=

+

<li>
- <p>modify <code>--with-pkg-config-libdir</code> option to
- make it possible to install “.pc” files even if

+ <p>A few entries use extensions (user-defined terminal

<ul>
<li>
- <p>improve configure script's <code>CF_CC_ENV_FLAGS</code>
- macro to allow for compiler wrappers such as <span class=
- "part-name">ccache</span>. This change moves only the
- preprocessor, optimization and warning flags to
- <code>CPPFLAGS</code> and <code>CFLAGS</code>, leaving the
- residue in <code>CC</code>. That happens to work for
- <span class="part-name">gcc</span>'s various
- “model” options, but may require tuning for other
- compilers.</p>
+ <p>use <tt>ansi+enq</tt> and <tt>decid+cpr</tt> in cases
+ where the terminal probably supported the u6-u9 extension</p>
+ </li>
+
+ <li>
+ <p>remove u6-u9 from teken-2018</p>
</li>
<li>
- <p>modify ncurses-examples' configure script to use

- form/menu/panel libraries, to be more consistent with the
- handling of the curses/ncurses library.</p>
+ <p>use <tt>NQ</tt> to flag entries where the terminal does

+ <h3><a name="h3-bug-fixes" id="h3-bug-fixes">Interesting
+ bug-fixes</a></h3>
+
+ <p>While there were many bugs fixed during development of ncurses
+ 6.4, only a few (the reason for this release) were both important
+ and interesting. Most of the bug-fixes were for local issues
+ which did not affect compatibility across releases. Since those
+ are detailed in the <a href=
+ "@HOMEPAGE@/NEWS.html#t20221231">NEWS</a> file no elaboration is
+ needed here.</p>
+
+ <p>The interesting bugs were those dealing with memory leaks and
+ buffer overflows. Although the utilities are designed for
+ <em>text</em> files (which they do properly), some choose to test
+ them with <strong>non-</strong><em>text</em> files.</p>
+
+ <ul>
+ <li>
+ <p>Text files contain no embedded nulls. Also, they end with
+ a newline. Feeding <strong>tic</strong> non-text files
+ exposed a few cases where the program did not check for those
+ issues. As a result, further processing of the input found
+ limit-checks whose assumptions were invalid.</p>
+ </li>
<li>
- <p>add “newer” baudrate symbols to the <a href=
- "https://invisible-island.net/ncurses/man/curs_termattrs.3x.html#h3-baudrate">
- <code>baudrate</code></a> function in the ncurses library as
- well as to a corresponding table in <span class=
- "part-name">tset</span>.</p>
+ <p>Fixing the limit-checks (first) found a problem with
+ <strong>tic</strong> managing the list of strings in a
+ terminal description. In merging two terminal descriptions
+ (i.e., the “use=” feature), <strong>tic</strong>
+ was not allocating a complete copy. A quick repair for that
+ introduced a memory leak.</p>
</li>
<li>
- <p>modify ncurses-examples <span class=
- "part-name">savescreen</span> to work with AIX and HPUX.</p>
+ <p>The checks for non-text files are improved (i.e., embedded
+ nulls in the input file will cause <strong>tic</strong> to
+ reject it rather than attempting to process it).</p>
</li>
<li>
- <p>define <code>WIN32_LEAN_AND_MEAN</code> for MinGW port,
- making builds faster.</p>
+ <p>The string allocations in <strong>tic</strong> are
+ likewise improved.</p>
</li>
+ </ul>

+
+ <p>Many of the portability changes are implemented via the
+ configure script:</p>
+ <ul>
<li>
- <p>add a configure check for <em>wcwidth</em> versus the
- <span class="main-name">ncurses</span> line-drawing
- characters, to use in special-casing systems such as Solaris.
- Solaris, however, requires a special case that maps Unicode
- line-drawing characters into the acsc string for non-Unicode
- locales. Solaris also has a misconfigured wcwidth which marks
- all of the line drawing characters as double-width.</p>
+ <p>amend configure option's auto-search to account for
+ systems where none of the directories known to
+ <em>pkg-config</em> exist</p>
</li>
<li>
- <p>string-hacks (non-standard):</p>
+ <p>corrected regex needed for older <em>pkg-config</em> used
+ in Solaris 10</p>
+ </li>
- <ul>
- <li>
- <p>fix configure script to record when

+ <p>fixes to build with <em>dietlibc</em>:</p>
<ul>
- <li>
- <p>see Debian #65617, which was fixed in <span class=
