- infocmp can be used to compare a binary terminfo entry
- with other terminfo entries, rewrite a terminfo descrip-
- tion to take advantage of the use= terminfo field, or
- print out a terminfo description from the binary file
- (term) in a variety of formats. In all cases, the boolean
- fields will be printed first, followed by the numeric
- fields, followed by the string fields.
-
- DefaultOptions
- If no options are specified and zero or one termnames are
- specified, the -I option will be assumed. If more than
- one termname is specified, the -d option will be assumed.
-
- ComparisonOptions[-d][-c][-n]
- infocmp compares the terminfo description of the first
- terminal termname with each of the descriptions given by
- the entries for the other terminal's termnames. If a
- capability is defined for only one of the terminals, the
- value returned will depend on the type of the capability:
- F for boolean variables, -1 for integer variables, and
- NULL for string variables.
-
- The -d 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 -c option produces a list of each capability that is
- common between two entries. Capabilities that are not set
- are ignored. This option can be used as a quick check to
- see if the -u option is worth using.
-
- The -n option produces a list of each capability that is
- in neither entry. If no termnames are given, the environ-
- ment variable TERM will be used for both of the termnames.
- This can be used as a quick check to see if anything was
- left out of a description.
-
- SourceListingOptions[-I][-L][-C][-r]
- The -I, -L, and -C options will produce a source listing
- for each terminal named.
-
- -I use the terminfo names
-
- -L use the long C variable name listed in <term.h>
- -C use the termcap names
- -r when using -C, put out all capabilities in termcap form
-
- If no termnames are given, the environment variable TERM
- will be used for the terminal name.
-
- The source produced by the -C option may be used directly
- as a termcap entry, but not all parameterized strings can
- be changed to the termcap format. infocmp 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.
-
- All padding information for strings will be collected
- together and placed at the beginning of the string where
- termcap expects it. Mandatory padding (padding informa-
- tion with a trailing '/') will become optional.
-
- All termcap variables no longer supported by terminfo, but
- which are derivable from other terminfo variables, will be
- output. Not all terminfo capabilities will be translated;
- only those variables which were part of termcap will nor-
- mally be output. Specifying the -r option will take off
- this restriction, allowing all capabilities to be output
- in termcap form.
-
- Note that because padding is collected to the beginning of
- the capability, not all capabilities are output. Manda-
- tory padding is not supported. Because termcap strings
- are not as flexible, it is not always possible to convert
- a terminfo string capability into an equivalent termcap
- format. A subsequent conversion of the termcap file back
- into terminfo format will not necessarily reproduce the
- original terminfo source.
-
- Some common terminfo parameter sequences, their termcap
- equivalents, and some terminal types which commonly have
- such sequences, are:

- Use=Option[-u]
- The -u option produces a terminfo source description of
- the first terminal termname which is relative to the sum
- of the descriptions given by the entries for the other
- terminals termnames. It does this by analyzing the
- differences between the first termname and the other
- termnames and producing a description with use= 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 infocmp 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
- longer exists in the first termname, but one of the other
- termname entries contains a value for it. A capability's
- value gets printed if the value in the first termname is
- not found in any of the other termname entries, or if the
- first of the other termname entries that has this capabil-
- ity gives a different value for the capability than that
- in the first termname.
-
- The order of the other termname entries is significant.
- Since the terminfo compiler tic does a left-to-right scan
- of the capabilities, specifying two use= entries that con-
- tain differing entries for the same capabilities will pro-
- duce different results depending on the order that the
- entries are given in. infocmp will flag any such incon-
- sistencies between the other termname entries as they are
- found.
-
- Alternatively, specifying a capability after a use= entry
- that contains that capability will cause the second speci-
- fication to be ignored. Using infocmp to recreate a
- description can be a useful check to make sure that every-
- thing was specified correctly in the original source
+
+ infocmp can be used to compare a binary terminfo entry with other ter-
+ minfo entries, rewrite a terminfo description to take advantage of the
+ use= terminfo field, or print out a terminfo description from the
+ binary file (term) in a variety of formats. In all cases, the boolean
+ fields will be printed first, followed by the numeric fields, followed
+ by the string fields.
+
+
+
+ If no options are specified and zero or one termnames are specified,
+ the -I option will be assumed. If more than one termname is specified,
+ the -d option will be assumed.
+
+
+
+ infocmp compares the terminfo description of the first terminal
+ termname with each of the descriptions given by the entries for the
+ other terminal's termnames. If a capability is defined for only one of
+ the terminals, the value returned depends on the type of the capabil-
+ ity:
+
+ oF for missing boolean variables
+
+ oNULL for missing integer or string variables
+
+ Use the -q option to show the distinction between absent and cancelled
+ capabilities.
+
+ These options produce a list which you can use to compare two or more
+ terminal descriptions:
+
+ -d produces a list of each capability that is different between two
+ entries. Each item in the list shows ":" after the capability
+ name, followed by the capability values, separated by a comma.
+
+ -c produces a list of each capability that is common between two or
+ more entries. Missing capabilities are ignored. Each item in the
+ list shows "=" after the capability name, followed by the capabil-
+ ity value.
+
+ The -u option provides a related output, showing the first termi-
+ nal description rewritten to use the second as a building block
+ via the "use=" clause.
+
+ -n produces a list of each capability that is in none of the given
+ entries. Each item in the list shows "!" before the capability
+ name.
+
+ Normally only the conventional capabilities are shown. Use the -x
+ option to add the BSD-compatibility capabilities (names prefixed
+ with "OT").
+
+ If no termnames are given, infocmp uses the environment variable
+ TERM for each of the termnames.
+
+
+
+ The -I, -L, and -C options will produce a source listing for each ter-
+ minal named.
+
+ -I use the terminfo names
+ -L use the long C variable name listed in <term.h>
+ -C use the termcap names
+ -r when using -C, put out all capabilities in termcap form
+ -K modifies the -C option, improving BSD-compatibility.
+
+ If no termnames are given, the environment variable TERM will be used
+ for the terminal name.
+
+ The source produced by the -C option may be used directly as a termcap
+ entry, but not all parameterized strings can be changed to the termcap
+ format. infocmp will attempt to convert most of the parameterized
+ information, and anything not converted will be plainly marked in the
+ output and commented out. These should be edited by hand.
+
+ For best results when converting to termcap format, you should use both
+ -C and -r. Normally a termcap description is limited to 1023 bytes.
+ infocmp trims away less essential 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 -T option. More
+ often however, you must help the termcap implementation, and trim
+ excess whitespace (use the -0 option for that).
+
+ All padding information for strings will be collected together and
+ placed at the beginning of the string where termcap expects it. Manda-
+ tory padding (padding information with a trailing "/") will become
+ optional.
+
+ All termcap variables no longer supported by terminfo, but which are
+ derivable from other terminfo variables, will be output. Not all ter-
+ minfo capabilities will be translated; only those variables which were
+ part of termcap will normally be output. Specifying the -r option will
+ take off this restriction, allowing all capabilities to be output in
+ termcap form. Normally you would use both the -C and -r options. The
+ actual format used incorporates some improvements for escaped charac-
+ ters from terminfo format. For a stricter BSD-compatible translation,
+ use the -K option rather than -C.
+
+ Note that because padding is collected to the beginning of the capabil-
+ ity, not all capabilities are output. Mandatory padding is not sup-
+ ported. Because termcap strings are not as flexible, it is not always
+ possible to convert a terminfo string capability into an equivalent
+ termcap format. A subsequent conversion of the termcap file back into
+ terminfo format will not necessarily reproduce the original terminfo
+ source.

ChangingDatabases[-Adirectory] [-B directory]
- The location of the compiled terminfo database is taken
- from the environment variable TERMINFO . If the variable
- is not defined, or the terminal is not found in that loca-
- tion, the system terminfo database, in /usr/share/ter-
- minfo, will be used. The options -A and -B may be used to
- override this location. The -A option will set TERMINFO
- for the first termname and the -B option will set TERMINFO
- for the other termnames. With this, it is possible to
- compare descriptions for a terminal with the same name
- located in two different databases. This is useful for
- comparing descriptions for the same terminal created by
- different people.

+
+ You can also use the options -A and -B to override the list of places

- -Rsubset
- Restrict output to a given subset. This option is
- for use with archaic versions of terminfo like those
- on SVr1, Ultrix, or HP/UX that do not support the
- full set of SVR4/XSI Curses terminfo; and variants
- such as AIX that have their own extensions incompati-
- ble with SVr4/XSI. Available terminfo subsets are
- "SVr1", "Ultrix", "HP", and "AIX"; see terminfo(5)
- for details. You can also choose the subset "BSD"
- which selects only capabilities with termcap equiva-
- lents recognized by 4.4BSD.
-
- -s[d|i|l|c]
- The -s option sorts the fields within each type
- according to the argument below:
-
- d leave fields in the order that they are stored
- in the terminfo database.
-
- i sort by terminfo name.
-
- l sort by the long C variable name.
-
- c sort by the termcap name.
-
- If the -s option is not given, the fields printed out
- will be sorted alphabetically by the terminfo name
- within each type, except in the case of the -C or the
- -L options, which cause the sorting to be done by the
- termcap name or the long C variable name, respec-
- tively.
-
- -T eliminates size-restrictions on the generated text.
- This is mainly useful for testing and analysis, since
- the compiled descriptions are limited (e.g., 1023 for
- termcap, 4096 for terminfo).
+ -Qn Rather than show source in terminfo (text) format, print the com-
+ piled (binary) format in hexadecimal or base64 form, depending on
+ the option's value:
- -t tells tic to discard commented-out capabilities.
- Normally when translating from terminfo to termcap,
- untranslatable capabilities are commented-out.
+ 1 hexadecimal
- -V reports the version of ncurses which was used in this
- program, and exits.
+ 2 base64
- -vn prints out tracing information on standard error as
- the program runs. Higher values of n induce greater
- verbosity.
+ 3 hexadecimal and base64
- -wwidth
- changes the output to width characters.
+ For example, this prints the compiled terminfo value as a string
+ which could be assigned to the TERMINFO environment variable:

EXTENSIONS
- The -E, -F, -G, -R, -T, -V, -a, -e, -f, -g, -i, -l, -p, -q
- and -t options are not supported in SVr4 curses.
-
- The -r option's notion of `termcap' capabilities is System
- V Release 4's. Actual BSD curses versions will have a
- more restricted set. To see only the 4.4BSD set, use -r
- -RBSD.
+ o However, show differences between absent and cancelled capa-
+ bilities.
+ o Omit the "Reconstructed from" comment for source listings.

+ -W By itself, the -w option will not force long strings to be
+ wrapped. Use the -W option to do this.
+ -wwidth
+ changes the output to width characters.
+ -x print information for user-defined capabilities. These are exten-
+ sions to the terminfo repertoire which can be loaded using the -x
+ option of tic.

+ The -0, -1, -E, -F, -G, -Q, -R, -T, -V, -a, -e, -f, -g, -i, -l, -p, -q
+ and -t options are not supported in SVr4 curses.
+ SVr4 infocmp does not distinguish between absent and cancelled capabil-
+ ities. Also, it shows missing integer capabilities as -1 (the internal
+ value used to represent missing integers). This implementation shows
+ those as "NULL", for consistency with missing strings.
+ The -r option's notion of "termcap" capabilities is System V Release
+ 4's. Actual BSD curses versions will have a more restricted set. To
+ see only the 4.4BSD set, use -r-RBSD.
