- <STRONG>infocmp</STRONG> compares the <STRONG>terminfo</STRONG> description of the first
- terminal <EM>termname</EM> with each of the descriptions given by
- the entries for the other terminal's <EM>termnames</EM>. If a
- capability is defined for only one of the terminals, the
- value returned will depend on the type of the capability:
- <STRONG>F</STRONG> for boolean variables, <STRONG>-1</STRONG> for integer variables, and
- <STRONG>NULL</STRONG> for string variables.
-
- The <STRONG>-d</STRONG> option produces a list of each capability that is
- different between two entries. This option is useful to
- show the difference between two entries, created by dif-
- ferent people, for the same or similar terminals.
-
- The <STRONG>-c</STRONG> option produces a list of each capability that is
- common between two or more entries. Capabilities that are
- not set are ignored. This option can be used as a quick
- check to see if the <STRONG>-u</STRONG> option is worth using.
-
- The <STRONG>-n</STRONG> option produces a list of each capability that is
- in none of the given entries. If no <EM>termnames</EM> are given,
- the environment variable <STRONG>TERM</STRONG> will be used for both of the
- <EM>termnames</EM>. This can be used as a quick check to see if
- anything was left out of a description.
+ <STRONG>infocmp</STRONG> compares the <STRONG>terminfo</STRONG> description of the first terminal
+ <EM>termname</EM> with each of the descriptions given by the entries for the
+ other terminal's <EM>termnames</EM>. If a capability is defined for only one of
+ the terminals, the value returned depends on the type of the
+ capability:
+
+ <STRONG>o</STRONG> <STRONG>F</STRONG> for missing boolean variables
+
+ <STRONG>o</STRONG> <STRONG>NULL</STRONG> for missing integer or string variables
+
+ Use the <STRONG>-q</STRONG> option to show the distinction between <EM>absent</EM> and <EM>cancelled</EM>
+ capabilities.
+
+ These options produce a list which you can use to compare two or more
+ terminal descriptions:
+
+ <STRONG>-d</STRONG> produces a list of each capability that is <EM>different</EM> between two
+ entries. Each item in the list shows ":" after the capability
+ name, followed by the capability values, separated by a comma.
+
+ <STRONG>-c</STRONG> produces a list of each capability that is <EM>common</EM> between two or
+ more entries. Missing capabilities are ignored. Each item in the
+ list shows "=" after the capability name, followed by the
+ capability value.
+
+ The <STRONG>-u</STRONG> option provides a related output, showing the first
+ terminal description rewritten to use the second as a building
+ block via the "use=" clause.
+
+ <STRONG>-n</STRONG> produces a list of each capability that is in <EM>none</EM> of the given
+ entries. Each item in the list shows "!" before the capability
+ name.
+
+ Normally only the conventional capabilities are shown. Use the <STRONG>-x</STRONG>
+ option to add the BSD-compatibility capabilities (names prefixed
+ with "OT").
+
+ If no <EM>termnames</EM> are given, <STRONG>infocmp</STRONG> uses the environment variable
+ <STRONG>TERM</STRONG> for each of the <EM>termnames</EM>.

- The <STRONG>-I</STRONG>, <STRONG>-L</STRONG>, and <STRONG>-C</STRONG> options will produce a source listing
- for each terminal named.
-
- <STRONG>-I</STRONG> use the <STRONG>terminfo</STRONG> names
- <STRONG>-L</STRONG> use the long C variable name listed in <<STRONG>term.h</STRONG>>
- <STRONG>-C</STRONG> use the <STRONG>termcap</STRONG> names
- <STRONG>-r</STRONG> when using <STRONG>-C</STRONG>, put out all capabilities in <STRONG>termcap</STRONG> form
- <STRONG>-K</STRONG> modifies the <STRONG>-C</STRONG> option, improving BSD-compatibility.
-
- If no <EM>termnames</EM> are given, the environment variable <STRONG>TERM</STRONG>
- will be used for the terminal name.
-
- The source produced by the <STRONG>-C</STRONG> option may be used directly
- as a <STRONG>termcap</STRONG> entry, but not all parameterized strings can
- be changed to the <STRONG>termcap</STRONG> format. <STRONG>infocmp</STRONG> will attempt to
- convert most of the parameterized information, and any-
- thing not converted will be plainly marked in the output
- and commented out. These should be edited by hand.
-
- For best results when converting to <STRONG>termcap</STRONG> format, you
- should use both <STRONG>-C</STRONG> and <STRONG>-r</STRONG>. Normally a termcap description
- is limited to 1023 bytes. infocmp trims away less essen-
- tial parts to make it fit. If you are converting to one
- of the (rare) termcap implementations which accept an
- unlimited size of termcap, you may want to add the <STRONG>-T</STRONG>
- option. More often however, you must help the termcap
- implementation, and trim excess whitespace (use the <STRONG>-0</STRONG>
- option for that).
-
- All padding information for strings will be collected
- together and placed at the beginning of the string where
- <STRONG>termcap</STRONG> expects it. Mandatory padding (padding informa-
- tion with a trailing '/') will become optional.
-
- All <STRONG>termcap</STRONG> variables no longer supported by <STRONG>terminfo</STRONG>, but
- which are derivable from other <STRONG>terminfo</STRONG> variables, will be
- output. Not all <STRONG>terminfo</STRONG> capabilities will be translated;
- only those variables which were part of <STRONG>termcap</STRONG> will nor-
- mally be output. Specifying the <STRONG>-r</STRONG> option will take off
- this restriction, allowing all capabilities to be output
- in <EM>termcap</EM> form. Normally you would use both the <STRONG>-C</STRONG> and
- <STRONG>-r</STRONG> options. The actual format used incorporates some
- improvements for escaped characters from terminfo format.
- For a stricter BSD-compatible translation, use the <STRONG>-K</STRONG>
- option rather than <STRONG>-C</STRONG>.
-
- Note that because padding is collected to the beginning of
- the capability, not all capabilities are output. Manda-
- tory padding is not supported. Because <STRONG>termcap</STRONG> strings
- are not as flexible, it is not always possible to convert
- a <STRONG>terminfo</STRONG> string capability into an equivalent <STRONG>termcap</STRONG>
- format. A subsequent conversion of the <STRONG>termcap</STRONG> file back
- into <STRONG>terminfo</STRONG> format will not necessarily reproduce the
- original <STRONG>terminfo</STRONG> source.
-
- Some common <STRONG>terminfo</STRONG> parameter sequences, their <STRONG>termcap</STRONG>
- equivalents, and some terminal types which commonly have
- such sequences, are:

- The <STRONG>-u</STRONG> option produces a <STRONG>terminfo</STRONG> source description of
- the first terminal <EM>termname</EM> which is relative to the sum
- of the descriptions given by the entries for the other
- terminals <EM>termnames</EM>. It does this by analyzing the dif-
- ferences between the first <EM>termname</EM> and the other
- <EM>termnames</EM> and producing a description with <STRONG>use=</STRONG> fields for
- the other terminals. In this manner, it is possible to
- retrofit generic terminfo entries into a terminal's
- description. Or, if two similar terminals exist, but were
- coded at different times or by different people so that
- each description is a full description, using <STRONG>infocmp</STRONG> will
- show what can be done to change one description to be rel-
- ative to the other.
-
- A capability will get printed with an at-sign (@) if it no

- first of the other <EM>termname</EM> entries that has this capabil-
- ity gives a different value for the capability than that
- in the first <EM>termname</EM>.
-
- The order of the other <EM>termname</EM> entries is significant.
- Since the terminfo compiler <STRONG>tic</STRONG> does a left-to-right scan

- tain differing entries for the same capabilities will pro-
- duce different results depending on the order that the

- sistencies between the other <EM>termname</EM> entries as they are

- <STRONG><term.h></STRONG>). This option is useful for preparing ver-
- sions of the curses library hardwired for a given
- terminal type. The tables are all declared static,
- and are named according to the type and the name of
- the corresponding terminal entry.
-
- Before ncurses 5.0, the split between the <STRONG>-e</STRONG> and <STRONG>-E</STRONG>

-
- <STRONG>-F</STRONG> compare terminfo files. This assumes that two fol-
- lowing arguments are filenames. The files are
- searched for pairwise matches between entries, with
- two entries considered to match if any of their names
- do. The report printed to standard output lists
- entries with no matches in the other file, and
- entries with more than one match. For entries with
- exactly one match it includes a difference report.

- references are not resolved before looking for dif-
- ferences, but resolution can be forced by also speci-

- if/then/else/endif expressions indented for readabil-
- ity.
-
- <STRONG>-G</STRONG> Display constant literals in decimal form rather than
- their character equivalents.
-
- <STRONG>-g</STRONG> Display constant character literals in quoted form
- rather than their decimal equivalents.
-
- <STRONG>-i</STRONG> Analyze the initialization (<STRONG>is1</STRONG>, <STRONG>is2</STRONG>, <STRONG>is3</STRONG>), and reset
- (<STRONG>rs1</STRONG>, <STRONG>rs2</STRONG>, <STRONG>rs3</STRONG>), strings in the entry, as well as
- those used for starting/stopping cursor-positioning
- mode (<STRONG>smcup</STRONG>, <STRONG>rmcup</STRONG>) as well as starting/stopping
- keymap mode (<STRONG>smkx</STRONG>, <STRONG>rmkx</STRONG>).
-
- For each string, the code tries to analyze it into
- actions in terms of the other capabilities in the
- entry, certain X3.64/ISO 6429/ECMA-48 capabilities,
- and certain DEC VT-series private modes (the set of
- recognized special sequences has been selected for
- completeness over the existing terminfo database).
- Each report line consists of the capability name,
- followed by a colon and space, followed by a print-
- able expansion of the capability string with sections
- matching recognized actions translated into {}-brack-
- eted descriptions.

+ <STRONG>-E</STRONG> Dump the capabilities of the given terminal as tables, needed in
+ the C initializer for a TERMTYPE structure (the terminal
+ capability structure in the <STRONG><term.h></STRONG>). This option is useful for
+ preparing versions of the curses library hardwired for a given
+ terminal type. The tables are all declared static, and are named
+ according to the type and the name of the corresponding terminal
+ entry.
+

+
+ <STRONG>-F</STRONG> compare terminfo files. This assumes that two following arguments
+ are filenames. The files are searched for pairwise matches
+ between entries, with two entries considered to match if any of
+ their names do. The report printed to standard output lists
+ entries with no matches in the other file, and entries with more
+ than one match. For entries with exactly one match it includes a
+ difference report. Normally, to reduce the volume of the report,
+ use references are not resolved before looking for differences,
+ but resolution can be forced by also specifying <STRONG>-r</STRONG>.
+
+ <STRONG>-f</STRONG> Display complex terminfo strings which contain if/then/else/endif
+ expressions indented for readability.
+
+ <STRONG>-G</STRONG> Display constant literals in decimal form rather than their

+ starting/stopping cursor-positioning mode (<STRONG>smcup</STRONG>, <STRONG>rmcup</STRONG>) as well
+ as starting/stopping keymap mode (<STRONG>smkx</STRONG>, <STRONG>rmkx</STRONG>).
+
+ For each string, the code tries to analyze it into actions in
+ terms of the other capabilities in the entry, certain X3.64/ISO
+ 6429/ECMA-48 capabilities, and certain DEC VT-series private modes
+ (the set of recognized special sequences has been selected for
+ completeness over the existing terminfo database). Each report
+ line consists of the capability name, followed by a colon and
+ space, followed by a printable expansion of the capability string
+ with sections matching recognized actions translated into
+ {}-bracketed descriptions.
+
+ Here is a list of the DEC/ANSI special sequences recognized:

+ Although System V Release 2 provided a terminfo library, it had no

+
+ Eric Raymond used the AT&T documentation in 1995 to provide an
+ equivalent <STRONG>infocmp</STRONG> for ncurses. In addition, he added a few new
+ features such as:
+
+ <STRONG>o</STRONG> the <STRONG>-e</STRONG> option, to support <EM>fallback</EM> (compiled-in) terminal
+ descriptions
+
+ <STRONG>o</STRONG> the <STRONG>-i</STRONG> option, to help with analysis
+
+ Later, Thomas Dickey added the <STRONG>-x</STRONG> (user-defined capabilities) option,
+ and the <STRONG>-E</STRONG> option to support fallback entries with user-defined
+ capabilities.
+
+ For a complete list, see the <EM>EXTENSIONS</EM> section.
