SYNOPSIS
/usr/bin/infocmp [-d] [-c] [-n] [-I] [-L] [-C] [-r] [-u] [-s | d | i |
l | c] [-v] [-V] [-1] [-w width] [-A directory] [-B directory]
[termname...]
DESCRIPTIONinfocmp 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 speci‐
fied and zero, or one termname is specified, the -I option is assumed.
If more than one termname is specified, the -d option is assumed.
OPTIONS
The -d , -c , and -n options can be used for comparisons. infocmp com‐
pares 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. Manda‐
tory padding (padding information with a trailing '/') will become
optional.
All termcap variables no longer supported by terminfo , but are deriv‐
able from other terminfo variables, will be displayed. Not all ter‐
minfo 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 dis‐
played in termcap form.
Note that because padding is collected to the beginning of the capabil‐
ity, not all capabilities are displayed. 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.
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 ter‐
minal'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 ter‐
minfo compiler tic does a left-to-right scan of the capabilities, spec‐
ifying 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 con‐
tains, 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 descrip‐
tion.
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.
-wwidth Changes the output to width characters.
The location of the compiled terminfo database is taken from the envi‐
ronment variable TERMINFO. If the variable is not defined, or the ter‐
minal is not found in that location, the system terminfo database, usu‐
ally 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 ter‐
minal created by different people.
