59 The <STRONG>tic</STRONG> command translates a <STRONG>terminfo</STRONG> file from source format into com-
60 piled format. The compiled format is necessary for use with the
61 library routines in <STRONG><A HREF="ncurses.3x.html">ncurses(3x)</A></STRONG>.
63 As described in <STRONG><A HREF="term.5.html">term(5)</A></STRONG>, the database may be either a directory tree
64 (one file per terminal entry) or a hashed database (one record per
65 entry). The <STRONG>tic</STRONG> command writes only one type of entry, depending on
68 <STRONG>o</STRONG> For directory trees, the top-level directory, e.g., /usr/share/ter-
69 minfo, specifies the location of the database.
71 <STRONG>o</STRONG> For hashed databases, a filename is needed. If the given file is
72 not found by that name, but can be found by adding the suffix
73 ".db", then that is used.
75 The default name for the hashed database is the same as the default
76 directory name (only adding a ".db" suffix).
78 In either case (directory or hashed database), <STRONG>tic</STRONG> will create the con-
79 tainer if it does not exist. For a directory, this would be the "ter-
80 minfo" leaf, versus a "terminfo.db" file.
82 The results are normally placed in the system terminfo database
83 <STRONG>/usr/share/terminfo</STRONG>. The compiled terminal description can be placed
84 in a different terminfo database. There are two ways to achieve this:
86 <STRONG>o</STRONG> First, you may override the system default either by using the <STRONG>-o</STRONG>
87 option, or by setting the variable <STRONG>TERMINFO</STRONG> in your shell environ-
88 ment to a valid database location.
90 <STRONG>o</STRONG> Secondly, if <STRONG>tic</STRONG> cannot write in <EM>/usr/share/terminfo</EM> or the loca-
91 tion specified using your TERMINFO variable, it looks for the
92 directory <EM>$HOME/.terminfo</EM> (or hashed database <EM>$HOME/.terminfo.db)</EM>;
93 if that location exists, the entry is placed there.
95 Libraries that read terminfo entries are expected to check in succes-
98 <STRONG>o</STRONG> a location specified with the TERMINFO environment variable,
100 <STRONG>o</STRONG> <EM>$HOME/.terminfo</EM>,
102 <STRONG>o</STRONG> directories listed in the TERMINFO_DIRS environment variable,
104 <STRONG>o</STRONG> a compiled-in list of directories (/usr/local/ncurses/share/ter-
105 minfo:/usr/share/terminfo), and
107 <STRONG>o</STRONG> the system terminfo database (<EM>/usr/share/terminfo</EM>).

111 This is the same program as infotocap and captoinfo; usually those are
112 linked to, or copied from this program:
114 <STRONG>o</STRONG> When invoked as infotocap, tic sets the <STRONG>-I</STRONG> option.
116 <STRONG>o</STRONG> When invoked as captoinfo, tic sets the <STRONG>-C</STRONG> option.
119 </PRE><H3><a name="h3-OPTIONS">OPTIONS</a></H3><PRE>
120 <STRONG>-0</STRONG> restricts the output to a single line
122 <STRONG>-1</STRONG> restricts the output to a single column
124 <STRONG>-a</STRONG> tells <STRONG>tic</STRONG> to retain commented-out capabilities rather than dis-
125 carding them. Capabilities are commented by prefixing them with
126 a period. This sets the <STRONG>-x</STRONG> option, because it treats the com-
127 mented-out entries as user-defined names. If the source is
128 termcap, accept the 2-character names required by version 6.
129 Otherwise these are ignored.
131 <STRONG>-C</STRONG> Force source translation to termcap format. Note: this differs
132 from the <STRONG>-C</STRONG> option of <STRONG><A HREF="infocmp.1m.html">infocmp(1m)</A></STRONG> in that it does not merely
133 translate capability names, but also translates terminfo strings
134 to termcap format. Capabilities that are not translatable are
135 left in the entry under their terminfo names but commented out
136 with two preceding dots. The actual format used incorporates
137 some improvements for escaped characters from terminfo format.
138 For a stricter BSD-compatible translation, add the <STRONG>-K</STRONG> option.
140 If this is combined with <STRONG>-c</STRONG>, <STRONG>tic</STRONG> makes additional checks to
141 report cases where the terminfo values do not have an exact
142 equivalent in termcap form. For example:
144 <STRONG>o</STRONG> <STRONG>sgr</STRONG> usually will not convert, because termcap lacks the
145 ability to work with more than two parameters, and because
146 termcap lacks many of the arithmetic/logical operators used
149 <STRONG>o</STRONG> capabilities with more than one delay or with delays before
150 the end of the string will not convert completely.
152 <STRONG>-c</STRONG> tells <STRONG>tic</STRONG> to only check <EM>file</EM> for errors, including syntax prob-
153 lems and bad use-links. If you specify <STRONG>-C</STRONG> (<STRONG>-I</STRONG>) with this
154 option, the code will print warnings about entries which, after
155 use resolution, are more than 1023 (4096) bytes long. Due to a
156 fixed buffer length in older termcap libraries, as well as buggy
157 checking for the buffer length (and a documented limit in ter-
158 minfo), these entries may cause core dumps with other implemen-
161 <STRONG>tic</STRONG> checks string capabilities to ensure that those with parame-
162 ters will be valid expressions. It does this check only for the
163 predefined string capabilities; those which are defined with the
164 <STRONG>-x</STRONG> option are ignored.
166 <STRONG>-D</STRONG> tells <STRONG>tic</STRONG> to print the database locations that it knows about,
167 and exit. The first location shown is the one to which it would
168 write compiled terminal descriptions. If <STRONG>tic</STRONG> is not able to
169 find a writable database location according to the rules summa-
170 rized above, it will print a diagnostic and exit with an error
171 rather than printing a list of database locations.
173 <STRONG>-e</STRONG> <EM>names</EM>
174 Limit writes and translations to the following comma-separated
175 list of terminals. If any name or alias of a terminal matches
176 one of the names in the list, the entry will be written or
177 translated as normal. Otherwise no output will be generated for
178 it. The option value is interpreted as a file containing the
179 list if it contains a '/'. (Note: depending on how tic was com-
180 piled, this option may require <STRONG>-I</STRONG> or <STRONG>-C</STRONG>.)
182 <STRONG>-f</STRONG> Display complex terminfo strings which contain
183 if/then/else/endif expressions indented for readability.
185 <STRONG>-G</STRONG> Display constant literals in decimal form rather than their
186 character equivalents.
188 <STRONG>-g</STRONG> Display constant character literals in quoted form rather than
189 their decimal equivalents.
191 <STRONG>-I</STRONG> Force source translation to terminfo format.
193 <STRONG>-K</STRONG> Suppress some longstanding ncurses extensions to termcap format,
194 e.g., "\s" for space.
196 <STRONG>-L</STRONG> Force source translation to terminfo format using the long C
197 variable names listed in <<STRONG>term.h</STRONG>>
199 <STRONG>-N</STRONG> Disable smart defaults. Normally, when translating from termcap
200 to terminfo, the compiler makes a number of assumptions about
201 the defaults of string capabilities <STRONG>reset1_string</STRONG>, <STRONG>car-</STRONG>
202 <STRONG>riage_return</STRONG>, <STRONG>cursor_left</STRONG>, <STRONG>cursor_down</STRONG>, <STRONG>scroll_forward</STRONG>, <STRONG>tab</STRONG>,
203 <STRONG>newline</STRONG>, <STRONG>key_backspace</STRONG>, <STRONG>key_left</STRONG>, and <STRONG>key_down</STRONG>, then attempts to
204 use obsolete termcap capabilities to deduce correct values. It
205 also normally suppresses output of obsolete termcap capabilities
206 such as <STRONG>bs</STRONG>. This option forces a more literal translation that
207 also preserves the obsolete capabilities.
209 <STRONG>-o</STRONG><EM>dir</EM> Write compiled entries to given database location. Overrides
210 the TERMINFO environment variable.
212 <STRONG>-Q</STRONG><EM>n</EM> Rather than show source in terminfo (text) format, print the
213 compiled (binary) format in hexadecimal or base64 form, depend-
214 ing on the option's value:
220 3 hexadecimal and base64
222 <STRONG>-q</STRONG> Suppress comments and blank lines when showing translated
225 <STRONG>-R</STRONG><EM>subset</EM>
226 Restrict output to a given subset. This option is for use with
227 archaic versions of terminfo like those on SVr1, Ultrix, or
228 HP/UX that do not support the full set of SVR4/XSI Curses ter-
229 minfo; and outright broken ports like AIX 3.x that have their
230 own extensions incompatible with SVr4/XSI. Available subsets
231 are "SVr1", "Ultrix", "HP", "BSD" and "AIX"; see <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG> for
234 <STRONG>-r</STRONG> Force entry resolution (so there are no remaining tc capabili-
235 ties) even when doing translation to termcap format. This may
236 be needed if you are preparing a termcap file for a termcap
237 library (such as GNU termcap through version 1.3 or BSD termcap
238 through 4.3BSD) that does not handle multiple tc capabilities
241 <STRONG>-s</STRONG> Summarize the compile by showing the database location into
242 which entries are written, and the number of entries which are
245 <STRONG>-T</STRONG> eliminates size-restrictions on the generated text. This is
246 mainly useful for testing and analysis, since the compiled
247 descriptions are limited (e.g., 1023 for termcap, 4096 for ter-
250 <STRONG>-t</STRONG> tells <STRONG>tic</STRONG> to discard commented-out capabilities. Normally when
251 translating from terminfo to termcap, untranslatable capabili-
252 ties are commented-out.
254 <STRONG>-U</STRONG> tells <STRONG>tic</STRONG> to not post-process the data after parsing the source
255 file. Normally, it infers data which is commonly missing in older
256 terminfo data, or in termcaps.
258 <STRONG>-V</STRONG> reports the version of ncurses which was used in this program, and
261 <STRONG>-v</STRONG><EM>n</EM> specifies that (verbose) output be written to standard error trace
262 information showing <STRONG>tic</STRONG>'s progress.
264 The optional parameter <EM>n</EM> is a number from 1 to 10, inclusive,
265 indicating the desired level of detail of information. If ncurses
266 is built without tracing support, the optional parameter is
267 ignored. If <EM>n</EM> is omitted, the default level is 1. If <EM>n</EM> is speci-
268 fied and greater than 1, the level of detail is increased.
270 The debug flag levels are as follows:
272 1 Names of files created and linked
274 2 Information related to the "use" facility
276 3 Statistics from the hashing algorithm
278 5 String-table memory allocations
280 7 Entries into the string-table
282 8 List of tokens encountered by scanner
284 9 All values computed in construction of the hash table
286 If the debug level <EM>n</EM> is not given, it is taken to be one.
288 <STRONG>-W</STRONG> By itself, the <STRONG>-w</STRONG> option will not force long strings to be
289 wrapped. Use the <STRONG>-W</STRONG> option to do this.
291 If you specify both <STRONG>-f</STRONG> and <STRONG>-W</STRONG> options, the latter is ignored when
292 <STRONG>-f</STRONG> has already split the line.
294 <STRONG>-w</STRONG><EM>n</EM> specifies the width of the output. The parameter is optional. If
295 it is omitted, it defaults to 60.
297 <STRONG>-x</STRONG> Treat unknown capabilities as user-defined (see <STRONG>user_caps(5)</STRONG>).
298 That is, if you supply a capability name which <STRONG>tic</STRONG> does not recog-
299 nize, it will infer its type (boolean, number or string) from the
300 syntax and make an extended table entry for that. User-defined
301 capability strings whose name begins with "k" are treated as func-
305 </PRE><H3><a name="h3-PARAMETERS">PARAMETERS</a></H3><PRE>
306 <EM>file</EM> contains one or more <STRONG>terminfo</STRONG> terminal descriptions in source
307 format [see <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG>]. Each description in the file
308 describes the capabilities of a particular terminal.
310 If <EM>file</EM> is "-", then the data is read from the standard input.
311 The <EM>file</EM> parameter may also be the path of a character-device.
314 </PRE><H3><a name="h3-PROCESSING">PROCESSING</a></H3><PRE>
315 All but one of the capabilities recognized by <STRONG>tic</STRONG> are documented in
316 <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG>. The exception is the <STRONG>use</STRONG> capability.
318 When a <STRONG>use</STRONG>=<EM>entry</EM>-<EM>name</EM> field is discovered in a terminal entry currently
319 being compiled, <STRONG>tic</STRONG> reads in the binary from <STRONG>/usr/share/terminfo</STRONG> to
320 complete the entry. (Entries created from <EM>file</EM> will be used first.
321 <STRONG>tic</STRONG> duplicates the capabilities in <EM>entry</EM>-<EM>name</EM> for the current entry,
322 with the exception of those capabilities that explicitly are defined in
325 When an entry, e.g., <STRONG>entry_name_1</STRONG>, contains a <STRONG>use=</STRONG><EM>entry</EM>_<EM>name</EM>_<EM>2</EM> field,
326 any canceled capabilities in <EM>entry</EM>_<EM>name</EM>_<EM>2</EM> must also appear in
327 <STRONG>entry_name_1</STRONG> before <STRONG>use=</STRONG> for these capabilities to be canceled in
328 <STRONG>entry_name_1</STRONG>.
330 Total compiled entries cannot exceed 4096 bytes. The name field cannot
331 exceed 512 bytes. Terminal names exceeding the maximum alias length
332 (32 characters on systems with long filenames, 14 characters otherwise)
333 will be truncated to the maximum alias length and a warning message
337 </PRE><H2><a name="h2-HISTORY">HISTORY</a></H2><PRE>
338 System V Release 2 provided a <STRONG>tic</STRONG> utility. It accepted a single
339 option: <STRONG>-v</STRONG> (optionally followed by a number). According to Ross
340 Ridge's comment in <EM>mytinfo</EM>, this version of <STRONG>tic</STRONG> was unable to represent
341 cancelled capabilities.
343 System V Release 3 provided a different <STRONG>tic</STRONG> utility, written by Pavel
344 Curtis, (originally named "compile" in <EM>pcurses</EM>). This added an option
345 <STRONG>-c</STRONG> to check the file for errors, with the caveat that errors in "use="
346 links would not be reported. System V Release 3 documented a few warn-
347 ing messages which did not appear in <EM>pcurses</EM>. While the program itself
348 was changed little as development continued with System V Release 4,
349 the table of capabilities grew from 180 (<EM>pcurses</EM>) to 464 (Solaris).
351 In early development of ncurses (1993), Zeyd Ben-Halim used the table
352 from <EM>mytinfo</EM> to extend the <EM>pcurses</EM> table to 469 capabilities (456
353 matched SVr4, 8 were only in SVr4, 13 were not in SVr4). Of those 13,
354 11 were ultimately discarded (perhaps to match the draft of X/Open
355 Curses). The exceptions were <STRONG>memory_lock_above</STRONG> and <STRONG>memory_unlock</STRONG> (see
356 <STRONG><A HREF="user_caps.5.html">user_caps(5)</A></STRONG>).
358 Eric Raymond incorporated parts of <EM>mytinfo</EM> into ncurses to implement
359 the termcap-to-terminfo source conversion, and extended that to begin
360 development of the corresponding terminfo-to-termcap source conversion,
361 Thomas Dickey completed that development over the course of several
364 In 1999, Thomas Dickey added the <STRONG>-x</STRONG> option to support user-defined
367 In 2010, Roy Marples provided a <STRONG>tic</STRONG> program and terminfo library for
368 NetBSD. That implementation adapts several features from ncurses,
369 including <STRONG>tic</STRONG>'s <STRONG>-x</STRONG> option.
371 The <STRONG>-c</STRONG> option tells <STRONG>tic</STRONG> to check for problems in the terminfo source
372 file. Continued development provides additional checks:
374 <STRONG>o</STRONG> <EM>pcurses</EM> had 8 warnings
376 <STRONG>o</STRONG> ncurses in 1996 had 16 warnings
378 <STRONG>o</STRONG> Solaris (SVr4) curses has 28 warnings
380 <STRONG>o</STRONG> NetBSD tic in 2019 has 19 warnings.
382 <STRONG>o</STRONG> ncurses in 2019 has 96 warnings
384 The checking done in ncurses' <STRONG>tic</STRONG> helps with the conversion to termcap,
385 as well as pointing out errors and inconsistencies. It is also used to
386 ensure consistency with the user-defined capabilities. There are 527
387 distinct capabilities in ncurses' terminal database; 128 of those are
391 </PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
392 X/Open Curses, Issue 7 (2009) provides a brief description of <STRONG>tic</STRONG>. It
393 lists one option: <STRONG>-c</STRONG>. The omission of <STRONG>-v</STRONG> is unexpected. The change
394 history states that the description is derived from True64 UNIX.
395 According to its manual pages, that system also supported the <STRONG>-v</STRONG>
398 Shortly after Issue 7 was released, Tru64 was discontinued. As of
399 2019, the surviving implementations of <STRONG>tic</STRONG> are SVr4 (AIX, HP-UX and
400 Solaris), ncurses and NetBSD curses. The SVr4 <STRONG>tic</STRONG> programs all support
401 the <STRONG>-v</STRONG> option. The NetBSD <STRONG>tic</STRONG> program follows X/Open's documentation,
402 omitting the <STRONG>-v</STRONG> option.
404 The X/Open rationale states that some implementations of <STRONG>tic</STRONG> read ter-
405 minal descriptions from the standard input if the <EM>file</EM> parameter is
406 omitted. None of these implementations do that. Further, it comments
407 that some may choose to read from "./terminfo.src" but that is obsoles-
408 cent behavior from SVr2, and is not (for example) a documented feature
412 </PRE><H3><a name="h3-COMPATIBILITY">COMPATIBILITY</a></H3><PRE>
413 There is some evidence that historic <STRONG>tic</STRONG> implementations treated
414 description fields with no whitespace in them as additional aliases or
415 short names. This <STRONG>tic</STRONG> does not do that, but it does warn when descrip-
416 tion fields may be treated that way and check them for dangerous char-
420 </PRE><H3><a name="h3-EXTENSIONS">EXTENSIONS</a></H3><PRE>
421 Unlike the SVr4 <STRONG>tic</STRONG> command, this implementation can actually compile
422 termcap sources. In fact, entries in terminfo and termcap syntax can
423 be mixed in a single source file. See <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG> for the list of
424 termcap names taken to be equivalent to terminfo names.
426 The SVr4 manual pages are not clear on the resolution rules for <STRONG>use</STRONG>
427 capabilities. This implementation of <STRONG>tic</STRONG> will find <STRONG>use</STRONG> targets any-
428 where in the source file, or anywhere in the file tree rooted at <STRONG>TER-</STRONG>
429 <STRONG>MINFO</STRONG> (if <STRONG>TERMINFO</STRONG> is defined), or in the user's <EM>$HOME/.terminfo</EM> data-
430 base (if it exists), or (finally) anywhere in the system's file tree of
433 The error messages from this <STRONG>tic</STRONG> have the same format as GNU C error
434 messages, and can be parsed by GNU Emacs's compile facility.
436 Aside from <STRONG>-c</STRONG> and <STRONG>-v</STRONG>, options are not portable:
438 <STRONG>o</STRONG> Most of tic's options are not supported by SVr4 <STRONG>tic</STRONG>:
440 <STRONG>-0</STRONG> <STRONG>-1</STRONG> <STRONG>-C</STRONG> <STRONG>-G</STRONG> <STRONG>-I</STRONG> <STRONG>-N</STRONG> <STRONG>-R</STRONG> <STRONG>-T</STRONG> <STRONG>-V</STRONG> <STRONG>-a</STRONG> <STRONG>-e</STRONG> <STRONG>-f</STRONG> <STRONG>-g</STRONG> <STRONG>-o</STRONG> <STRONG>-r</STRONG> <STRONG>-s</STRONG> <STRONG>-t</STRONG> <STRONG>-x</STRONG>
442 <STRONG>o</STRONG> The NetBSD <STRONG>tic</STRONG> supports a few of the ncurses options
444 <STRONG>-a</STRONG> <STRONG>-o</STRONG> <STRONG>-x</STRONG>
446 and adds <STRONG>-S</STRONG> (a feature which does the same thing as infocmp's <STRONG>-e</STRONG>
447 and <STRONG>-E</STRONG> options).
449 The SVr4 <STRONG>-c</STRONG> mode does not report bad "use=" links.
451 System V does not compile entries to or read entries from your
452 <EM>$HOME/.terminfo</EM> database unless TERMINFO is explicitly set to it.
