default termcap terminal capability database

NAME

captoinfo - convert a termcap description into a terminfo description

SYNOPSIS

captoinfo [tic-option] [file ...]

captoinfo -V

captoinfo translates terminal descriptions. It looks in each given text file for termcap entries and, for each one found, writes an equivalent terminfo description to the standard output stream. termcaptc capabilities translate to terminfo “use” capabilities.

If no files are specified, captoinfo interprets the content of the environment variable TERMCAP as a file name, and extracts only the entry for the terminal named in the environment variable TERM from it. If the environment variable TERMCAP is not set, captoinfo reads /etc/termcap.

This utility is implemented as a link to tic(1), with the latter's -I option implied. You can use other tic options such as -1, -f, -v, -w, and -x. The -V option reports the version of ncurses associated with this program and exits with a successful status.

Translations from Nonstandard Capabilities

captoinfo translates some obsolete, nonstandard capabilities into standard terminfo capabilities. It issues a diagnostic to the standard error stream for each, inviting the user to check that it has not mistakenly translated an unknown or mistyped capability name.

XENIX termcap had a set of extension capabilities, corresponding to box drawing characters of CCSID (“code page”) 437, as follows.

G4	lower right corner

captoinfo composes single-line capabilities into an acsc string, and discards GG and double-line capabilities with a warning diagnostic.

IBM's AIX has a terminfo facility descended from SVr1 terminfo, but which is incompatible with the SVr4 format. captoinfo translates the following AIX extensions.

IBM	X/Open
ksel	kslt
kbtab	kcbt
font0	s0ds
font1	s1ds
font2	s2ds
font3	s3ds

Additionally, this program translates the AIX box1 capability to an acsc string.

The HP-UX terminfo library supports two nonstandard terminfo capabilities, meml (memory lock) and memu (memory unlock). captoinfo discards these with a warning message.

PORTABILITY

X/Open Curses Issue 7 (2009) describes tic briefly, but omits this program.

SVr4 systems provide captoinfo as a separate application from tic. Its -v option does not accept a trace level argument n; repeat -vn times instead.

NetBSD does not provide this application.
