64 <STRONG>infocmp</STRONG> can be used to compare a binary <STRONG>terminfo</STRONG> entry
65 with other terminfo entries, rewrite a <STRONG>terminfo</STRONG> descrip-
66 tion to take advantage of the <STRONG>use=</STRONG> terminfo field, or
67 print out a <STRONG>terminfo</STRONG> description from the binary file
68 (<STRONG>term</STRONG>) in a variety of formats. In all cases, the boolean
69 fields will be printed first, followed by the numeric
70 fields, followed by the string fields.
74 <H3><a name="h3-Default-Options">Default Options</a></H3><PRE>
75 If no options are specified and zero or one <EM>termnames</EM> are
76 specified, the <STRONG>-I</STRONG> option will be assumed. If more than
77 one <EM>termname</EM> is specified, the <STRONG>-d</STRONG> option will be assumed.
81 <H3><a name="h3-Comparison-Options-_-d_-_-c_-_-n_">Comparison Options [-d] [-c] [-n]</a></H3><PRE>
82 <STRONG>infocmp</STRONG> compares the <STRONG>terminfo</STRONG> description of the first
83 terminal <EM>termname</EM> with each of the descriptions given by
84 the entries for the other terminal's <EM>termnames</EM>. If a
85 capability is defined for only one of the terminals, the
86 value returned will depend on the type of the capability:
87 <STRONG>F</STRONG> for boolean variables, <STRONG>-1</STRONG> for integer variables, and
88 <STRONG>NULL</STRONG> for string variables.
90 The <STRONG>-d</STRONG> option produces a list of each capability that is
91 different between two entries. This option is useful to
92 show the difference between two entries, created by dif-
93 ferent people, for the same or similar terminals.
95 The <STRONG>-c</STRONG> option produces a list of each capability that is
96 common between two or more entries. Capabilities that are
97 not set are ignored. This option can be used as a quick
98 check to see if the <STRONG>-u</STRONG> option is worth using.
100 The <STRONG>-n</STRONG> option produces a list of each capability that is
101 in none of the given entries. If no <EM>termnames</EM> are given,
102 the environment variable <STRONG>TERM</STRONG> will be used for both of the
103 <EM>termnames</EM>. This can be used as a quick check to see if
104 anything was left out of a description.
108 <H3><a name="h3-Source-Listing-Options-_-I_-_-L_-_-C_-_-r_">Source Listing Options [-I] [-L] [-C] [-r]</a></H3><PRE>
109 The <STRONG>-I</STRONG>, <STRONG>-L</STRONG>, and <STRONG>-C</STRONG> options will produce a source listing
110 for each terminal named.
112 <STRONG>-I</STRONG> use the <STRONG>terminfo</STRONG> names
113 <STRONG>-L</STRONG> use the long C variable name listed in <<STRONG>term.h</STRONG>>
114 <STRONG>-C</STRONG> use the <STRONG>termcap</STRONG> names
115 <STRONG>-r</STRONG> when using <STRONG>-C</STRONG>, put out all capabilities in <STRONG>termcap</STRONG> form
116 <STRONG>-K</STRONG> modifies the <STRONG>-C</STRONG> option, improving BSD-compatibility.
118 If no <EM>termnames</EM> are given, the environment variable <STRONG>TERM</STRONG>
119 will be used for the terminal name.
121 The source produced by the <STRONG>-C</STRONG> option may be used directly
122 as a <STRONG>termcap</STRONG> entry, but not all parameterized strings can
123 be changed to the <STRONG>termcap</STRONG> format. <STRONG>infocmp</STRONG> will attempt to
124 convert most of the parameterized information, and any-
125 thing not converted will be plainly marked in the output
126 and commented out. These should be edited by hand.
128 For best results when converting to <STRONG>termcap</STRONG> format, you
129 should use both <STRONG>-C</STRONG> and <STRONG>-r</STRONG>. Normally a termcap description
130 is limited to 1023 bytes. infocmp trims away less essen-
131 tial parts to make it fit. If you are converting to one
132 of the (rare) termcap implementations which accept an
133 unlimited size of termcap, you may want to add the <STRONG>-T</STRONG>
134 option. More often however, you must help the termcap
135 implementation, and trim excess whitespace (use the <STRONG>-0</STRONG>
138 All padding information for strings will be collected
139 together and placed at the beginning of the string where
140 <STRONG>termcap</STRONG> expects it. Mandatory padding (padding informa-
141 tion with a trailing '/') will become optional.
143 All <STRONG>termcap</STRONG> variables no longer supported by <STRONG>terminfo</STRONG>, but
144 which are derivable from other <STRONG>terminfo</STRONG> variables, will be
145 output. Not all <STRONG>terminfo</STRONG> capabilities will be translated;
146 only those variables which were part of <STRONG>termcap</STRONG> will nor-
147 mally be output. Specifying the <STRONG>-r</STRONG> option will take off
148 this restriction, allowing all capabilities to be output
149 in <EM>termcap</EM> form. Normally you would use both the <STRONG>-C</STRONG> and
150 <STRONG>-r</STRONG> options. The actual format used incorporates some
151 improvements for escaped characters from terminfo format.
152 For a stricter BSD-compatible translation, use the <STRONG>-K</STRONG>
153 option rather than <STRONG>-C</STRONG>.
155 Note that because padding is collected to the beginning of
156 the capability, not all capabilities are output. Manda-
157 tory padding is not supported. Because <STRONG>termcap</STRONG> strings
158 are not as flexible, it is not always possible to convert
159 a <STRONG>terminfo</STRONG> string capability into an equivalent <STRONG>termcap</STRONG>
160 format. A subsequent conversion of the <STRONG>termcap</STRONG> file back
161 into <STRONG>terminfo</STRONG> format will not necessarily reproduce the
162 original <STRONG>terminfo</STRONG> source.
164 Some common <STRONG>terminfo</STRONG> parameter sequences, their <STRONG>termcap</STRONG>
165 equivalents, and some terminal types which commonly have
168 <STRONG>terminfo</STRONG> <STRONG>termcap</STRONG> Representative Terminals

179 <H3><a name="h3-Use_-Option-_-u_">Use= Option [-u]</a></H3><PRE>
180 The <STRONG>-u</STRONG> option produces a <STRONG>terminfo</STRONG> source description of
181 the first terminal <EM>termname</EM> which is relative to the sum
182 of the descriptions given by the entries for the other
183 terminals <EM>termnames</EM>. It does this by analyzing the dif-
184 ferences between the first <EM>termname</EM> and the other
185 <EM>termnames</EM> and producing a description with <STRONG>use=</STRONG> fields for
186 the other terminals. In this manner, it is possible to
187 retrofit generic terminfo entries into a terminal's
188 description. Or, if two similar terminals exist, but were
189 coded at different times or by different people so that
190 each description is a full description, using <STRONG>infocmp</STRONG> will
191 show what can be done to change one description to be rel-
194 A capability will get printed with an at-sign (@) if it no
195 longer exists in the first <EM>termname</EM>, but one of the other
196 <EM>termname</EM> entries contains a value for it. A capability's
197 value gets printed if the value in the first <EM>termname</EM> is
198 not found in any of the other <EM>termname</EM> entries, or if the
199 first of the other <EM>termname</EM> entries that has this capabil-
200 ity gives a different value for the capability than that
201 in the first <EM>termname</EM>.
203 The order of the other <EM>termname</EM> entries is significant.
204 Since the terminfo compiler <STRONG>tic</STRONG> does a left-to-right scan
205 of the capabilities, specifying two <STRONG>use=</STRONG> entries that con-
206 tain differing entries for the same capabilities will pro-
207 duce different results depending on the order that the
208 entries are given in. <STRONG>infocmp</STRONG> will flag any such incon-
209 sistencies between the other <EM>termname</EM> entries as they are
212 Alternatively, specifying a capability <EM>after</EM> a <STRONG>use=</STRONG> entry
213 that contains that capability will cause the second speci-
214 fication to be ignored. Using <STRONG>infocmp</STRONG> to recreate a
215 description can be a useful check to make sure that every-
216 thing was specified correctly in the original source
219 Another error that does not cause incorrect compiled
220 files, but will slow down the compilation time, is speci-
221 fying extra <STRONG>use=</STRONG> fields that are superfluous. <STRONG>infocmp</STRONG>
222 will flag any other <EM>termname</EM> <EM>use=</EM> fields that were not
225 <STRONG>Changing</STRONG> <STRONG>Databases</STRONG> <STRONG>[-A</STRONG> <EM>directory</EM>] [-B <EM>directory</EM>]
226 Like other <STRONG>ncurses</STRONG> utilities, infocmp looks for the termi-
227 nal descriptions in several places. You can use the <STRONG>TER-</STRONG>
228 <STRONG>MINFO</STRONG> and <STRONG>TERMINFO_DIRS</STRONG> environment variables to override
229 the compiled-in default list of places to search (see
230 <STRONG><A HREF="ncurses.3x.html">curses(3x)</A></STRONG> for details).
232 You can also use the options <STRONG>-A</STRONG> and <STRONG>-B</STRONG> to override the
233 list of places to search when comparing terminal descrip-
236 <STRONG>o</STRONG> The <STRONG>-A</STRONG> option sets the location for the first <EM>termname</EM>
238 <STRONG>o</STRONG> The <STRONG>-B</STRONG> option sets the location for the other
241 Using these options, it is possible to compare descrip-
242 tions for a terminal with the same name located in two
243 different databases. For instance, you can use this fea-
244 ture for comparing descriptions for the same terminal cre-
245 ated by different people.
249 <H3><a name="h3-Other-Options">Other Options</a></H3><PRE>
250 <STRONG>-0</STRONG> causes the fields to be printed on one line, without
253 <STRONG>-1</STRONG> causes the fields to be printed out one to a line.
254 Otherwise, the fields will be printed several to a
255 line to a maximum width of 60 characters.
257 <STRONG>-a</STRONG> tells <STRONG>infocmp</STRONG> to retain commented-out capabilities
258 rather than discarding them. Capabilities are com-
259 mented by prefixing them with a period.
261 <STRONG>-D</STRONG> tells <STRONG>infocmp</STRONG> to print the database locations that it
262 knows about, and exit.
264 <STRONG>-E</STRONG> Dump the capabilities of the given terminal as
265 tables, needed in the C initializer for a TERMTYPE
266 structure (the terminal capability structure in the
267 <STRONG><term.h></STRONG>). This option is useful for preparing ver-
268 sions of the curses library hardwired for a given
269 terminal type. The tables are all declared static,
270 and are named according to the type and the name of
271 the corresponding terminal entry.
273 Before ncurses 5.0, the split between the <STRONG>-e</STRONG> and <STRONG>-E</STRONG>
274 options was not needed; but support for extended
275 names required making the arrays of terminal capabil-
276 ities separate from the TERMTYPE structure.
278 <STRONG>-e</STRONG> Dump the capabilities of the given terminal as a C
279 initializer for a TERMTYPE structure (the terminal
280 capability structure in the <STRONG><term.h></STRONG>). This option
281 is useful for preparing versions of the curses
282 library hardwired for a given terminal type.
284 <STRONG>-F</STRONG> compare terminfo files. This assumes that two fol-
285 lowing arguments are filenames. The files are
286 searched for pairwise matches between entries, with
287 two entries considered to match if any of their names
288 do. The report printed to standard output lists
289 entries with no matches in the other file, and
290 entries with more than one match. For entries with
291 exactly one match it includes a difference report.
292 Normally, to reduce the volume of the report, use
293 references are not resolved before looking for dif-
294 ferences, but resolution can be forced by also speci-
295 fying <STRONG>-r</STRONG>.
297 <STRONG>-f</STRONG> Display complex terminfo strings which contain
298 if/then/else/endif expressions indented for readabil-
301 <STRONG>-G</STRONG> Display constant literals in decimal form rather than
302 their character equivalents.
304 <STRONG>-g</STRONG> Display constant character literals in quoted form
305 rather than their decimal equivalents.
307 <STRONG>-i</STRONG> Analyze the initialization (<STRONG>is1</STRONG>, <STRONG>is2</STRONG>, <STRONG>is3</STRONG>), and reset
308 (<STRONG>rs1</STRONG>, <STRONG>rs2</STRONG>, <STRONG>rs3</STRONG>), strings in the entry. For each
309 string, the code tries to analyze it into actions in
310 terms of the other capabilities in the entry, certain
311 X3.64/ISO 6429/ECMA-48 capabilities, and certain DEC
312 VT-series private modes (the set of recognized spe-
313 cial sequences has been selected for completeness
314 over the existing terminfo database). Each report
315 line consists of the capability name, followed by a
316 colon and space, followed by a printable expansion of
317 the capability string with sections matching recog-
318 nized actions translated into {}-bracketed descrip-
319 tions. Here is a list of the DEC/ANSI special
320 sequences recognized: i.

359 It also recognizes a SGR action corresponding to
360 ANSI/ISO 6429/ECMA Set Graphics Rendition, with the
361 values NORMAL, BOLD, UNDERLINE, BLINK, and REVERSE.
362 All but NORMAL may be prefixed with `+' (turn on) or
365 An SGR0 designates an empty highlight sequence
366 (equivalent to {SGR:NORMAL}).
368 <STRONG>-l</STRONG> Set output format to terminfo.
370 <STRONG>-p</STRONG> Ignore padding specifications when comparing strings.
372 <STRONG>-q</STRONG> Make the comparison listing shorter by omitting sub-
373 headings, and using "-" for absent capabilities, "@"
374 for canceled rather than "NULL".
376 <STRONG>-R</STRONG><EM>subset</EM>
377 Restrict output to a given subset. This option is
378 for use with archaic versions of terminfo like those
379 on SVr1, Ultrix, or HP/UX that do not support the
380 full set of SVR4/XSI Curses terminfo; and variants
381 such as AIX that have their own extensions incompati-
382 ble with SVr4/XSI. Available terminfo subsets are
383 "SVr1", "Ultrix", "HP", and "AIX"; see <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG>
384 for details. You can also choose the subset "BSD"
385 which selects only capabilities with termcap equiva-
386 lents recognized by 4.4BSD.
388 <STRONG>-s</STRONG> <EM>[d|i|l|c]</EM>
389 The <STRONG>-s</STRONG> option sorts the fields within each type
390 according to the argument below:
392 <STRONG>d</STRONG> leave fields in the order that they are stored
393 in the <EM>terminfo</EM> database.
395 <STRONG>i</STRONG> sort by <EM>terminfo</EM> name.
397 <STRONG>l</STRONG> sort by the long C variable name.
399 <STRONG>c</STRONG> sort by the <EM>termcap</EM> name.
401 If the <STRONG>-s</STRONG> option is not given, the fields printed out
402 will be sorted alphabetically by the <STRONG>terminfo</STRONG> name
403 within each type, except in the case of the <STRONG>-C</STRONG> or the
404 <STRONG>-L</STRONG> options, which cause the sorting to be done by the
405 <STRONG>termcap</STRONG> name or the long C variable name, respec-
408 <STRONG>-T</STRONG> eliminates size-restrictions on the generated text.
409 This is mainly useful for testing and analysis, since
410 the compiled descriptions are limited (e.g., 1023 for
411 termcap, 4096 for terminfo).
413 <STRONG>-t</STRONG> tells <STRONG>tic</STRONG> to discard commented-out capabilities.
414 Normally when translating from terminfo to termcap,
415 untranslatable capabilities are commented-out.
417 <STRONG>-U</STRONG> tells <STRONG>infocmp</STRONG> to not post-process the data after
418 parsing the source file. This feature helps when
419 comparing the actual contents of two source files,
420 since it excludes the inferences that <STRONG>infocmp</STRONG> makes
421 to fill in missing data.
423 <STRONG>-V</STRONG> reports the version of ncurses which was used in this
426 <STRONG>-v</STRONG> <EM>n</EM> prints out tracing information on standard error as
427 the program runs. Higher values of n induce greater
430 <STRONG>-w</STRONG> <EM>width</EM>
431 changes the output to <EM>width</EM> characters.
433 <STRONG>-x</STRONG> print information for user-defined capabilities.
434 These are extensions to the terminfo repertoire which
435 can be loaded using the <STRONG>-x</STRONG> option of <STRONG>tic</STRONG>.
