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

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

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