captoinfo

NAME

captoinfo - convert a termcap description into a terminfo description

SYNOPSIS

captoinfo [-vn width] [-V] [-1] [-w width] file . . .

DESCRIPTION

captoinfo looks in file for termcap descriptions. For each one found, an equivalent terminfo description is written to standard output. Termcap tc capabilities are translated directly to terminfo use capabilities.

If no file is given, then the environment variable TERMCAP is used for the filename or entry. If TERMCAP is a full pathname to a file, only the terminal whose name is specified in the environment variable TERM is extracted from that file. If the environment variable TERMCAP is not set, then the file /usr/share/terminfo is read.

-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

cause the fields to print out one to a line. Otherwise, the fields will be printed several to a line to a maximum width of 60 characters.

-w

change the output to width characters.

FILES

/usr/share/terminfo

Compiled terminal description database.

TRANSLATIONS FROM NONSTANDARD CAPABILITIES

Some obsolete nonstandard capabilities will automatically be translated into standard (SVr4/XSI Curses) terminfo capabilities by captoinfo. Whenever one of these automatic translations is done, the program will issue an notification to stderr, inviting the user to check that it has not mistakenly translated a completely unknown and random capability and/or syntax error.

XENIX termcap also used to have a set of extension capabilities for forms drawing, designed to take advantage of the IBM PC high-half graphics. They were as follows:

Cap	Graphic
G2	upper left
G3	lower left
G1	upper right
G4	lower right
GR	pointing right
GL	pointing left
GU	pointing up
GD	pointing down
GH	horizontal line
GV	vertical line
GC	intersection
G6	upper left
G7	lower left
G5	upper right
G8	lower right
Gr	tee pointing right
Gr	tee pointing left
Gu	tee pointing up
Gd	tee pointing down
Gh	horizontal line
Gv	vertical line
Gc	intersection
GG	acs magic cookie count

If the single-line capabilities occur in an entry, they will automatically be composed into an acsc string. The double-line capabilities and GG are discarded with a warning message.

IBM's AIX has a terminfo facility descended from SVr1 terminfo but incompatible with the SVr4 format. The following AIX extensions are automatically translated:

IBM	XSI
ksel	kslt
kbtab	kcbt
font0	s0ds
font1	s1ds
font2	s2ds
font3	s3ds

Additionally, the AIX box1 capability will be automatically translated to an acsc string.

Hewlett-Packard's terminfo library supports two nonstandard terminfo capabilities meml (memory lock) and memu (memory unlock). These will be discarded with a warning message.

NOTES

This utility is actually a link to tic(1), running in -I mode. You can use other tic options such as -f and -x.

The trace option is not identical to SVr4's. Under SVr4, instead of following the -v with a trace level n, you repeat it n times.
