.SH DESCRIPTION
|
|
.I tconv
|
|
converts between the three terminal descriptions,
|
|
termcap, terminfo source, and terminfo binary,
|
|
that the
|
|
.I tinfo
|
|
library uses.
|
|
It performs the same functions of
|
|
.IR captoinfo (1M)
|
|
and
|
|
.IR tic (1M)
|
|
of System V.
|
|
It also can be used to generate a terminfo source listing from a terminfo
|
|
binary, one of the functions of System V's
|
|
.IR infocmp (1M).

If a file is specified, one of

or

must specified and the whole file while be translated.
|

If no file is specified then the input options will only restrict looking
|
|
for the terminal to be translated in places likely have descriptions
|
|
of the desired type
|
|
(ie. with the
|
|
.B -c
|
|
option in the
|
|
.B TERMCAP
|
|
environment variable, and in

|
.IR /etc/termcap ,

|
with the
|
|
.B -i
|
|
option in the
|

.B TERMINFO

environment variable, and in

|
.IR /usr/lib/terminfo ),

otherwise
|

.I tconv

will look in all available databases.

If neither

.B \-I
|
|
or
|
|
.B \-B
|
|
are given the
|
|
.B \-I
|
|
option will be assumed.
|
|
If the

.B \-B
|

option is used, the compiled output will be put in the the

terminfo database, otherwise standard output is used.

.PP
|
|
You cannot translate from terminfo binary to terminfo binary.
|
|
Translating from terminfo source to terminfo source is possible,
|
|
but not of much use in most cases, as
|
|
.B use=
|
|
fields will be followed and incorporated into the output terminal
|
|
description.
|
|
.PP
|
|
.I tconv
|
|
should be able translate all standard termcap parameterized strings
|
|
terminfo format, but complex strings using GNU's %a code may be
|
|
too hard to translate.
|
|
If
|
|
.I tconv
|
|
thinks a termcap string is already in terminfo format (if a %p
|
|
code appears in the string), it won't try to translate it.
|
|
String capabilities that don't take parameters won't be translated.

.SH DIAGNOSTICS
|
|
The line number of a warning message when translating a file
|
|
may refer to the last line of an entry instead of the line in the entry
|
|
that generated the warning.
|
|
.SH BUGS
|
|
More warning messages could be generated.
|
|
.I tconv
|
|
can't translate to termcap. Binaries generated will have cancelled
|
|
capabilities marked as cancelled, which is incompatible with
|
|
System V Release 2.0 terminfo.
