infocmp compares a binary terminfo entry with other terminfo
entries, rewrites a terminfo description to take advantage of the use=
terminfo field, or prints out a terminfo description from the binary file
( term ) in a variety of formats. It displays boolean fields first, then
numeric fields, followed by the string fields. If no options are specified
and zero, or one termname is specified, the -I option is assumed. If more
than one termname is specified, the -d option is assumed.
The -d ,
-c , and -n options can be used for comparisons. infocmp compares the terminfo
description of the first terminal termname with each of the descriptions
given by the entries for the other terminal’s termname. 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.
- -d
- Produce a list of each capability that
is different between two entries. This option is useful to show the difference
between two entries, created by different people, for the same or similar
terminals.
- -c
- Produce 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.
- -n
- Produce a list
of each capability that is in neither entry. If no termname is given, the
environment 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.
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. The source produced by the -C option may
be used directly as a termcap entry, but not all of the parameterized strings
may be changed to the termcap format. infocmp will attempt to convert most
of the parameterized information, but anything not converted will be plainly
marked in the output and commented out. These should be edited by hand.
- -r
- When using -C , put out all capabilities in termcap form.
If no termname
is given, the environment variable TERM
will be used for the terminal
name.
All padding information for strings will be collected together and
placed at the beginning of the string where termcap expects it. Mandatory
padding (padding information with a trailing ’/’) will become optional.
All
termcap variables no longer supported by terminfo , but are derivable from
other terminfo variables, will be displayed. Not all terminfo capabilities
will be translated; only those variables which were part of termcap will
normally be displayed. Specifying the -r option will take off this restriction,
allowing all capabilities to be displayed in termcap form.
Note that because
padding is collected to the beginning of the capability, not all capabilities
are displayed. Mandatory 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:
terminfo termcap Representative Terminals
%p1%c %. adm
%p1%d %d hp, ANSI standard, vt100
%p1%’x’%+%c %+x concept
%i %i ANSI standard, vt100
%p1%?%’x’%>%t%p1%’y’%+%; %>xy concept
%p2 is printed before %p1 %r hp
- -u
- Produce 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 relative
to the other.
A capability is displayed 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 is displayed 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 capability gives a different
value for that capability.
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 contain differing entries for the same
capabilities will produce different results, depending on the order in
which the entries are given. infocmp will flag any such inconsistencies
between the other termname entries as they are found.
Alternatively, specifying
a capability after a use= entry that contains, it will cause the second
specification to be ignored. Using infocmp to recreate a description can
be a useful check to make sure that everything was specified correctly
in the original source description.
Another error that does not cause incorrect
compiled files, but will slow down the compilation time, is specifying
superfluous use= fields. infocmp will flag any superfluous use= fields.
- -s
- 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 are 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, respectively.
- -v
- Print out tracing information on standard
error as the program runs.
- -V
- Print out the version of the program in use
on standard error and exit.
- -1
- Print the fields one to a line. Otherwise,
the fields are printed several to a line to a maximum width of 60 characters.
- -w width
- Changes the output to width characters.
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 location,
the system terminfo database, usually in /usr/share/lib/terminfo, is used.
The options -A and -B may be used to override this location.
- -A directory
- Set
TERMINFO
for the first termname.
- -B directory
- 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.
- /usr/share/lib/terminfo/?/*
- Compiled terminal description database.
