12193354Srmacklem<H1>Announcing ncurses 5.2</H1>
13193354Srmacklem
14193354SrmacklemThe ncurses (new curses) library is a free software emulation of
15193354Srmacklemcurses in System V Release 4.0, and more.  It uses terminfo format,
16193354Srmacklemsupports pads and color
17193354Srmacklemand multiple highlights and forms characters and function-key mapping,
18193354Srmacklemand has all the other SYSV-curses enhancements over BSD curses.<P>
19193354Srmacklem
20In mid-June 1995, the maintainer of 4.4BSD curses declared that he
21considered 4.4BSD curses obsolete, and is encouraging the keepers of
22Unix releases such as BSD/OS, freeBSD and netBSD to switch over to
23ncurses.<P>
24
25The ncurses code was developed under GNU/Linux.  It should port easily to
26any ANSI/POSIX-conforming UNIX.  It has even been ported to OS/2 Warp!<P>
27
28The distribution includes the library and support utilities, including a
29terminfo compiler tic(1), a decompiler infocmp(1), clear(1), tput(1), tset(1),
30and a termcap conversion tool captoinfo(1).  Full manual pages are provided for
31the library and tools.<P>
32
33The ncurses distribution is available via anonymous FTP at
34the GNU distribution site
35<A HREF="ftp://ftp.gnu.org/pub/gnu/ncurses">ftp://ftp.gnu.org/pub/gnu/ncurses</A>.
36<br>It is also available at
37<A HREF="ftp://dickey.his.com/ncurses">ftp://dickey.his.com/ncurses</A>.

39<H1>Release Notes</H1>
40
41This release is designed to be upward compatible from ncurses 5.0 and 5.1;
42very few applications will require recompilation, depending on the platform.
43These are the highlights from the change-log since ncurses 5.1 release.
44<p>
45Interface changes:
46<ul>
47	<li>change type of <code>ospeed</code> variable back to
48	  <code>short</code> to match its use in legacy applications.  It was
49	  altered after ncurses 4.2 to <code>speed_t</code> to repair a type
50	  mismatch which was introduced after 1.9.4 in 1995.  The principal
51	  users of termcap continued to use <code>short</code>, which is
52	  not the same size.
53	  <p>
54	  <em>NOTE</em>: A few applications will have to be recompiled
55	  (about 1% of the programs in a typical Linux distribution,
56	  10% of the programs that use ncurses).  These are easy to
57	  identify with <code>nm</code> or <code>strings</code>.
58
59	<li>remove a private function <code>_nc_can_clear_with()</code>, which
60	  was built with the configure --enable-expanded option but not used.
61
62	<li>add several private functions (prefixed with "_nc_") for tracing
63	  <code>chtype</code> values in the debug library, and for better
64	  access and buffer limit checking.
65</ul>
66New features and improvements:
67<ul>
68	<li>rewrote <code>tgoto()</code> to make it better support existing
69	  termcap applications which use hardcoded strings rather than obtain
70	  all of their information from the termcap file.  If the string does
71	  not appear to be a terminfo string (i.e., does not refer to a "%p"
72	  parameter, or terminfo-style padding), and termcap support is configured, <code>tgoto()</code>
73	  will interpret it as termcap.  Otherwise, as before, it will use
74	  <code>tparm()</code>.
75
76	<li>to ensure that the <code>tgoto()</code> changes work properly,
77	  added checks to <code>tic</code> which report capabilities that do
78	  not reference the expected number of parameters.
79
80	<li>new configure script options:
81	<ul>
82	  <li>option <code>--disable-root-environ</code> adds runtime checks
83	    which tell ncurses to disregard $TERMINFO and similar environment
84	    variables if the current user is root, or running setuid/setgid.
85
86	  <li>option <code>--disable-assumed-color</code> allows you to use the
87	    pre-5.1 convention of default colors used for color-pair 0 to be
88	    configured (see assume_default_colors()).
89
90	  <li>implement configure script options that transform installed
91	    program names, e.g., <code>--program-prefix</code>, including the
92	    manpage names and cross references.
93
94	  <li>option <code>--with-database</code> allows you to specify a
95	    different terminfo source-file to install.  On OS/2 EMX, the
96	    default is misc/emx.src, otherwise misc/terminfo.src
97
98	  <li>option <code>--with-default-terminfo-dir</code> allows you to
99	    specify the default terminfo database directory.
100
101	  <li>option <code>--with-libtool</code> allows you to build with
102	    <code>libtool</code>.  <p> <em>NOTE</em>:  <code>libtool</code>
103	    uses a different notation for numbering shared library versions
104	    from the existing ncurses configuration.
105
106	  <li>option <code>--with-manpage-tbl</code> causes the manpages to be
107	    preprocessed by tbl(1) prior to installation,
108
109	  <li>option <code>--without-curses-h</code> causes the installation
110	    process to install curses.h as ncurses.h and make appropriate
111	    changes to headers and manpages.
112	</ul>
113
114	<li>modified configure script options:
115	<ul>
116	  <li>change symbol used by the <code>--install-prefix</code> configure
117	    option from <code>INSTALL_PREFIX</code> to <code>DESTDIR</code>
118	    (the latter has become common usage although the name is
119	    misleading).
120
121	  <li>modify <code>ld -rpath</code> options (e.g., Linux, and Solaris)
122	    to use an absolute pathname for the build tree's lib directory,
123	    avoiding confusion with directories relative to the current one
124	    with the installed programs.
125
126	  <li>modified <code>misc/run_tic.in</code> to use
127	    <code>tic&nbsp;-o</code>, to eliminate dependency on
128	    <code>$TERMINFO</code> variable for installs.
129	</ul>
130
131	<li>terminfo database:
132	<ul>
133	  <li>updated xterm terminfo entries to match XFree86 xterm patch #146.
134
135	  <li>added amiga-vnc,
136	    Matrix Orbital, and
137	    QNX qansi to misc/terminfo.src.
138
139	  <li>added os2 entry to misc/emx.src.
140
141	  <li>add S0 and E0 extensions to <code>screen</code>'s terminfo entry
142	    since otherwise the FreeBSD port makes it pass termcap equivalents
143	    to <code>tgoto</code>, which would be misinterpreted by older
144	    versions of ncurses.
145	</ul>
146
147	<li>improvements to program usability:
148	<ul>
149	  <li>modify programs to use <code>curses_version()</code> string to
150	    report the version of ncurses with which they are compiled rather
151	    than the NCURSES_VERSION string.  The function returns the patch
152	    level in addition to the major and minor version numbers.
153
154	  <li>modify <code>tput</code> program so it can be renamed or invoked via a link as
155	    'reset' or 'init', producing the same effect as <code>tput&nbsp;reset</code> or <code>tput&nbsp;init</code>.
156
157	  <li>add error checking to infocmp's -v and -m options to ensure that
158	    the option value is indeed a number.
159	</ul>
160
161	<li>improved performance:
162	<ul>
163	  <li>replace a lookup table in lib_vidattr.c used to decode
164	    <code>no_color_video</code> with a logic expression which is faster.
165	</ul>
166
167</ul>
168Major bug fixes:
169<ul>
170	<li>correct <code>manlinks.sed</code> script introduced in ncurses 5.1
171	  to avoid using ERE "\+", which is not understood by standard versions
172	  of <code>sed</code>.  This happens to work with GNU <code>sed</code>,
173	  but is not portable, and was the initial motivation for this release.
174
175	<li>remove "hpux10.*" case from CF_SHARED_OPTS configure script macro.
176	  This differed from the "hpux*" case by using reversed symbolic
177	  links, which made the 5.1 version not match the configuration of
178	  5.0 shared libraries.
179
180	<li>guard against corrupt terminfo data:
181	  <ul>
182	  <li>modify <code>tparm()</code> to disallow arithmetic on strings,
183	    analyze the varargs list to read strings as strings and numbers as
184	    numbers.
185
186	  <li>modify <code>tparm()</code>'s internal function
187	    <code>spop()</code> to treat a null pointer as an empty string.
188
189	  <li>modify <code>parse_format()</code> in lib_tparm.c to ignore
190	    precision if it is longer than 10000.
191
192	  <li>rewrote limit checks in lib_mvcur.c using new functions
193	    <code>_nc_safe_strcat()</code>, etc.  Made other related changes to
194	    check lengths used for <code>strcat()</code> and
195	    <code>strcpy()</code>.
196	  </ul>
197
198	<li>corrections to screen optimization:
199	  <ul>
200	  <li>added special case in lib_vidattr.c to reset underline and
201	    standout for devices that have no sgr0 defined.
202
203	  <li>change handling of <code>non_dest_scroll_region</code> in
204	    tty_update.c to clear text after it is shifted in rather than before
205	    shifting out.  Also correct row computation.
206
207	  <li>modify <code>rs2</code> capability in xterm-r6 and similar entries
208	    where cursor save/restore bracketed the sequence for resetting video
209	    attributes.  The cursor restore would undo that.
210	  </ul>
211
212	<li>UTF-8 support:
213	<ul>
214	  <li>when checking LC_ALL, LC_CTYPE, and LANG environment variables
215	    for UTF-8 locale, ignore those which are set to an empty value, as
216	    per SUSV2.
217
218	  <li>encode 0xFFFD in UTF-8 with 3 bytes, not 2.
219
220	  <li>modify <code>_nc_utf8_outch()</code> to avoid sign-extension when
221	    checking for out-of-range value.
222	</ul>
223
224	<li>other library fixes:
225	<ul>
226	  <li>added checks for an empty <code>$HOME</code> environment
227	    variable, to avoid retrieving terminfo descriptions from
228	    <code>./.terminfo</code> .
229
230	  <li>change functions <code>_nc_parse_entry()</code> and
231	    <code>postprocess_termcap()</code> to avoid using
232	    <code>strtok()</code>, because it is non-reentrant.
233
234	  <li>initialize <code>fds[]</code> array to 0's in
235	    <code>_nc_timed_wait()</code>; apparently <code>poll()</code> only
236	    sets the <code>revents</code> members of that array when there is
237	    activity corresponding to the related file.
238
239	  <li>add a check for null pointer in <code>Make_Enum_Type()</code>.
240
241	  <li>fix a heap problem with the c++ binding.
242
243	  <li>correct missing includes for &lt;string.h&gt; in several places,
244	    including the C++ binding.  This is not noted by gcc unless we use
245	    the <code>-fno-builtin</code> option.
246	</ul>
247
248	<li>several fixes for tic:
249	  <ul>
250	  <li>add a check for empty buffers returned by <code>fgets()</code> in
251	    comp_scan.c <code>next_char()</code> function, in case
252	    <code>tic</code> is run on a non-text file (fixes a core dump).
253
254	  <li>modify <code>tic</code> to verify that its inputs are really files,
255	    in case someone tries to read a directory (or
256	    <code>/dev/zero</code>).
257
258	  <li>correct an uninitialized parameter to <code>open_tempfile()</code>
259	    in tic.c which made "tic -I" give an ambiguous error message about
260	    <code>tmpnam</code>.
261
262	  <li>correct logic in <code>adjust_cancels()</code>, which did not check
263	    both alternatives when reclassifying an extended name between
264	    boolean, number and string, causing an infinite loop in
265	    <code>tic</code>.
266	  </ul>
267
268	<li>using new checks in <code>tic</code> for parameter counts in
269	  capability strings, found/fixed several errors both in the
270	  terminfo database and in the include/Caps file.
271	  <ul>
272	  <li>modified several terminfo capability strings, including the
273	    definitions for setaf, setab, in include/Caps to indicate that the
274	    entries are parameterized.  This information is used to tell which
275	    strings are translated when converting to termcap.  This fixes a
276	    problem where the generated termcap would contain a spurious "%p1"
277	    for the terminfo "%p1%d".
278
279	  <li>correct parameter counts in include/Caps for dclk as well as some
280	    printer-specific capabilities: csnm, defc, scs, scsd, smgtp, smglp.
281	  </ul>
282
283	<li>various fixes for install scripts used to support configure
284	  <code>--srcdir</code> and <code>--with-install-prefix</code>.
285
286	<li>correct several mismatches between manpage filename and ".TH"
287	  directives, renaming dft_fgbg.3x to default_colors.3x and
288	  menu_attribs.3x to menu_attributes.3x.
289</ul>
290
291Portability:
292<ul>
293	<li>configure script:
294	<ul>
295	  <li>newer config.guess, config.sub, including changes to support OS/2
296	    EMX.  The configure script for OS/2 EMX still relies on a patch
297	    since there is no (working) support for that platform in the main
298	    autoconf distribution.
299
300	  <li>make configure script checks on variables <code>$GCC</code> and
301	    <code>$GXX</code> consistently compare against 'yes' rather than
302	    test if they are nonnull, since either may be set to the
303	    corresponding name of the C or C++ compiler.
304
305	  <li>change configure script to use AC_CANONICAL_SYSTEM rather than
306	    AC_CANONICAL_HOST, which means that <code>configure --target</code>
307	    will set a default program-prefix.
308
309	  <li>modify the check for big-core to force a couple of memory
310	    accesses, which may work as needed for older/less-capable machines
311	    (if not, there's still the explicit configure option).
312
313	  <li>modify configure test for <code>tcgetattr()</code> to allow for
314	    old implementations, e.g., on BeOS, which only defined it as a
315	    macro.
316
317	  <li>add configure check for filesystems (such as OS/2 EMX) which do
318	    not distinguish between upper/lowercase filenames, use this to fix
319	    tags rules in makefiles.
320
321	  <li>add MKncurses_def.sh to generate fallback definitions for
322	    ncurses_cfg.h, to quiet gcc -Wundef warnings, modified ifdef's in
323	    code to consistently use "#if" rather than "#ifdef".
324
325	  <li>change most remaining unquoted parameters of <code>test</code> in
326	    configure script to use quotes, for instance fixing a problem in the
327	    <code>--disable-database</code> option.
328
329	  <li>modify scripts so that "make install.data" works on OS/2 EMX.
330
331	  <li>modify scripts and makefiles so the Ada95 directory builds on
332	    OS/2 EMX.
333	</ul>
334
335	<li>library:
336	<ul>
337	<li>replaced case-statement in <code>_nc_tracebits()</code> for CSIZE
338	  with a table to simplify working around implementations that define
339	  random combinations of the related macros to zero.
340
341	<li>improved OS/2 mouse support by retrying as a 2-button mouse if code
342	  fails to set up a 3-button mouse.
343
344	<li>added private entrypoint <code>_nc_basename()</code>, used to
345	  consolidate related code in progs, as well as accommodating OS/2 EMX
346	  pathnames.
347
348	<li>alter definition of NCURSES_CONST to make it non-empty.
349
350	<li>redefine 'TEXT' in menu.h for AMIGA, since it is reported to have
351	  an (unspecified) symbol conflict.
352	</ul>
353
354	<li>programs:
355	<ul>
356	  <li>modified progs/tset.c and tack/sysdep.c to build with sgttyb
357	    interface if neither termio or termios is available.  Tested this
358	    with FreeBSD 2.1.5 (which does have termios - but the sgttyb does
359	    work).
360	</ul>
361
362</ul>
363
364<H1>Features of Ncurses</H1>
365
366The ncurses package is fully compatible with SVr4 (System V Release 4) curses:
367
368<UL>
369<LI>All 257 of the SVr4 calls have been implemented (and are documented).
370<LI>Full support for SVr4 curses features including keyboard mapping, color,
371forms-drawing with ACS characters, and automatic recognition of keypad
372and function keys.
373<LI>An emulation of the SVr4 panels library, supporting
374a stack of windows with backing store, is included.
375<LI>An emulation of the SVr4 menus library, supporting
376a uniform but flexible interface for menu programming, is included.
377<LI>An emulation of the SVr4 form library, supporting
378data collection through on-screen forms, is included.
379<LI>Binary terminfo entries generated by the ncurses tic(1) implementation
380are bit-for-bit-compatible with the entry format SVr4 curses uses.
381<LI>The utilities have options to allow you to filter terminfo
382entries for use with less capable <STRONG>curses</STRONG>/<STRONG>terminfo</STRONG>
383versions such as the HP/UX and AIX ports.</UL>
384
385The ncurses package also has many useful extensions over SVr4:
386
387<UL>
388<LI>The API is 8-bit clean and base-level conformant with the X/OPEN curses
389specification, XSI curses (that is, it implements all BASE level features,
390but not all EXTENDED features).  Most EXTENDED-level features not directly
391concerned with wide-character support are implemented, including many
392function calls not supported under SVr4 curses (but portability of all
393calls is documented so you can use the SVr4 subset only).
394<LI>Unlike SVr3 curses, ncurses can write to the rightmost-bottommost corner
395of the screen if your terminal has an insert-character capability.
396<LI>Ada95 and C++ bindings.
397<LI>Support for mouse event reporting with X Window xterm and OS/2 console windows.
398<LI>Extended mouse support via Alessandro Rubini's gpm package.
399<LI>The function <CODE>wresize()</CODE> allows you to resize windows, preserving
400their data.
401<LI>The function <CODE>use_default_colors()</CODE> allows you to
402use the terminal's default colors for the default color pair,
403achieving the effect of transparent colors.
404<LI>The functions <CODE>keyok()</CODE>
405and <CODE>define_key()</CODE> allow
406you to better control the use of function keys,
407e.g., disabling the ncurses KEY_MOUSE,
408or by defining more than one control sequence to map to a given key code.
409<LI>Support for 16-color terminals, such as aixterm and XFree86 xterm.
410<LI>Better cursor-movement optimization.  The package now features a
411cursor-local-movement computation more efficient than either BSD's
412or System V's.
413<LI>Super hardware scrolling support.  The screen-update code incorporates
414a novel, simple, and cheap algorithm that enables it to make optimal
415use of hardware scrolling, line-insertion, and line-deletion
416for screen-line movements.  This algorithm is more powerful than
417the 4.4BSD curses quickch() routine.
418<LI>Real support for terminals with the magic-cookie glitch.  The
419screen-update code will refrain from drawing a highlight if the magic-
420cookie unattributed spaces required just before the beginning and
421after the end would step on a non-space character.  It will
422automatically shift highlight boundaries when doing so would make it
423possible to draw the highlight without changing the visual appearance
424of the screen.
425<LI>It is possible to generate the library with a list of pre-loaded
426fallback entries linked to it so that it can serve those terminal types even
427when no terminfo tree or termcap file is accessible (this may be useful
428for support of screen-oriented programs that must run in single-user mode).
429<LI>The tic(1)/captoinfo utility provided with ncurses has the
430ability to translate many termcaps from the XENIX, IBM and
431AT&amp;T extension sets.
432<LI>A BSD-like tset(1) utility is provided.
433<LI>The ncurses library and utilities will automatically read terminfo
434entries from $HOME/.terminfo if it exists, and compile to that directory
435if it exists and the user has no write access to the system directory.
436This feature makes it easier for users to have personal terminfo entries
437without giving up access to the system terminfo directory.
438<LI>You may specify a path of directories to search for compiled
439descriptions with the environment variable TERMINFO_DIRS (this
440generalizes the feature provided by TERMINFO under stock System V.)
441<LI>In terminfo source files, use capabilities may refer not just to
442other entries in the same source file (as in System V) but also to
443compiled entries in either the system terminfo directory or the user's
444$HOME/.terminfo directory.
445<LI>A script (<STRONG>capconvert</STRONG>) is provided to help BSD users
446transition from termcap to terminfo.  It gathers the information in a
447TERMCAP environment variable and/or a ~/.termcap local entries file
448and converts it to an equivalent local terminfo tree under $HOME/.terminfo.
449<LI>Automatic fallback to the /etc/termcap file can be compiled in
450when it is not possible to build a terminfo tree.  This feature is neither
451fast nor cheap, you don't want to use it unless you have to,
452but it's there.
453<LI>The table-of-entries utility <STRONG>toe</STRONG> makes it easy for users to

463<H1>State of the Package</H1>
464
465Numerous bugs present in earlier versions have been fixed; the
466library is far more reliable than it used to be.  Bounds checking in many
467`dangerous' entry points has been improved.  The code is now type-safe
468according to gcc -Wall.  The library has been checked for malloc leaks and
469arena corruption by the Purify memory-allocation tester.<P>
