.SH DESCRIPTION
|
|
The command \fBtic\fR translates a \fBterminfo\fR file from source
|
|
format into compiled format. The compiled format is necessary for use with
|
|
the library routines in \fBncurses\fR(3X).
|
|
.PP
|
|
The results are normally placed in the system terminfo
|
|
directory \fB\*d\fR. There are two ways to change this behavior.
|
|
.PP
|
|
First, you may override the system default by setting the variable
|
|
\fBTERMINFO\fR in your shell environment to a valid (existing) directory name.
|
|
.PP
|
|
Secondly, if \fBtic\fR cannot get access to \fI\*d\fR or your TERMINFO
|
|
directory, it looks for the directory \fI$HOME/.terminfo\fR; if that directory
|
|
exists, the entry is placed there.
|
|
.PP
|
|
Libraries that read terminfo entries are expected to check for a TERMINFO
|
|
directory first, look at \fI$HOME/.terminfo\fR if TERMINFO is not set, and
|
|
finally look in \fI\*d\fR.
|
|
.TP
|
|
\fB-a\fR
|
|
tells \fBtic\fP to retain commented-out capabilities rather than discarding
|
|
them. Capabilities are commented by prefixing them with a period.
|
|
This sets the \fB-x\fR option, because it treats the commented-out
|
|
entries as user-defined names.
|
|
.TP
|
|
\fB-c\fR
|
|
tells \fBtic\fP to only check \fIfile\fR for errors, including syntax problems and
|
|
bad use links. If you specify \fB-C\fR (\fB-I\fR) with this option, the code
|
|
will print warnings about entries which, after use resolution, are more than
|
|
1023 (4096) bytes long. Due to a fixed buffer length in older termcap
|
|
libraries (and a documented limit in terminfo), these entries may cause core
|
|
dumps.
|
|
.TP
|
|
\fB-v\fR\fIn\fR
|
|
specifies that (verbose) output be written to standard error trace
|
|
information showing \fBtic\fR's progress. The optional integer
|
|
\fIn\fR is a number from 1 to 10, inclusive, indicating the desired
|
|
level of detail of information. If \fIn\fR is omitted, the default
|
|
level is 1. If \fIn\fR is specified and greater than 1, the level of
|
|
detail is increased.
|
|
.TP
|
|
\fB-o\fR\fIdir\fR
|
|
Write compiled entries to given directory. Overrides the TERMINFO environment
|
|
variable.
|
|
.TP
|
|
\fB-w\fR\fIn\fR
|
|
specifies the width of the output.
|
|
.TP
|
|
\fB-1\fR
|
|
restricts the output to a single column
|
|
.TP
|
|
\fB-C\fR
|
|
Force source translation to termcap format. Note: this differs from the -C
|
|
option of \fIinfocmp\fR(1M) in that it does not merely translate capability
|
|
names, but also translates terminfo strings to termcap format. Capabilities
|
|
that are not translatable are left in the entry under their terminfo names
|
|
but commented out with two preceding dots.
|
|
.TP
|
|
\fB-G\fR
|
|
Display constant literals in decimal form
|
|
rather than their character equivalents.
|
|
.TP
|
|
\fB-I\fR
|
|
Force source translation to terminfo format.
|
|
.TP
|
|
\fB-L\fR
|
|
Force source translation to terminfo format
|
|
using the long C variable names listed in <\fBterm.h\fR>
|
|
.TP
|
|
\fB-N\fR
|
|
Disable smart defaults.
|
|
Normally, when translating from termcap to terminfo, the compiler makes
|
|
a number of assumptions about the defaults of string capabilities
|
|
\fBreset1_string\fR, \fBcarriage_return\fR, \fBcursor_left\fR,
|
|
\fBcursor_down\fR, \fBscroll_forward\fR, \fBtab\fR, \fBnewline\fR,
|
|
\fBkey_backspace\fR, \fBkey_left\fR, and \fBkey_down\fR, then attempts
|
|
to use obsolete termcap capabilities to deduce correct values. It also
|
|
normally suppresses output of obsolete termcap capabilities such as \fBbs\fR.
|
|
This option forces a more literal translation that also preserves the
|
|
obsolete capabilities.
|
|
.TP
|
|
\fB-R\fR\fIsubset\fR
|
|
Restrict output to a given subset. This option is for use with archaic
|
|
versions of terminfo like those on SVr1, Ultrix, or HP/UX that don't support
|
|
the full set of SVR4/XSI Curses terminfo; and outright broken ports like AIX 3.x
|
|
that have their own extensions incompatible with SVr4/XSI. Available subsets
|
|
are "SVr1", "Ultrix", "HP", "BSD" and "AIX"; see \fBterminfo\fR(\*n) for details.
|
|
.TP
|
|
\fB-T\fR
|
|
eliminates size-restrictions on the generated text.
|
|
This is mainly useful for testing and analysis, since the compiled
|
|
descriptions are limited (e.g., 1023 for termcap, 4096 for terminfo).
|
|
.TP
|
|
\fB-V\fR
|
|
reports the version of ncurses which was used in this program, and exits.
|
|
.TP
|
|
\fB-r\fR
|
|
Force entry resolution (so there are no remaining tc capabilities) even
|
|
when doing translation to termcap format. This may be needed if you are
|
|
preparing a termcap file for a termcap library (such as GNU termcap up
|
|
to version 1.3 or BSD termcap up to 4.3BSD) that doesn't handle multiple
|
|
tc capabilities per entry.
|
|
.TP
|
|
\fB-e\fR
|
|
Limit writes and translations to the following comma-separated list of
|
|
terminals.
|
|
If any name or alias of a terminal matches one of the names in
|
|
the list, the entry will be written or translated as normal.
|
|
Otherwise no output will be generated for it.
|
|
The option value is interpreted as a file containing the list if it
|
|
contains a '/'.
|
|
(Note: depending on how tic was compiled, this option may require -I or -C.)
|
|
.TP
|
|
\fB-f\fR
|
|
Display complex terminfo strings which contain if/then/else/endif expressions
|
|
indented for readability.
|
|
.TP
|
|
\fB-g\fR
|
|
Display constant character literals in quoted form
|
|
rather than their decimal equivalents.
|
|
.TP
|
|
\fB-s\fR
|
|
Summarize the compile by showing the directory into which entries
|
|
are written, and the number of entries which are compiled.
|
|
.TP
|
|
\fB-x\fR
|
|
Treat unknown capabilities as user-defined.
|
|
That is, if you supply a capability name which \fBtic\fP does not recognize,
|
|
it will infer its type (boolean, number or string) from the syntax and
|
|
make an extended table entry for that.
|
|
.TP
|
|
\fIfile\fR
|
|
contains one or more \fBterminfo\fR terminal descriptions in source
|
|
format [see \fBterminfo\fR(\*n)]. Each description in the file
|
|
describes the capabilities of a particular terminal.
|
|

|
|
.PP
|
|
All but one of the capabilities recognized by \fBtic\fR are documented
|
|
in \fBterminfo\fR(\*n). The exception is the \fBuse\fR capability.
|
|
|
|
When a \fBuse\fR=\fIentry\fR-\fIname\fR field is discovered in a
|
|
terminal entry currently being compiled, \fBtic\fR reads in the binary
|
|
from \fB\*d\fR to complete the entry. (Entries created from
|
|
\fIfile\fR will be used first. If the environment variable
|
|
\fBTERMINFO\fR is set, that directory is searched instead of
|
|
\fB\*d\fR.) \fBtic\fR duplicates the capabilities in
|
|
\fIentry\fR-\fIname\fR for the current entry, with the exception of
|
|
those capabilities that explicitly are defined in the current entry.
|
|
|
|
When an entry, e.g., \fBentry_name_1\fR, contains a
|
|
\fBuse=\fR\fIentry\fR_\fIname\fR_\fI2\fR field, any canceled
|
|
capabilities in \fIentry\fR_\fIname\fR_\fI2\fR must also appear in
|
|
\fBentry_name_1\fR before \fBuse=\fR for these capabilities to be
|
|
canceled in \fBentry_name_1\fR.
|
|
|
|
If the environment variable \fBTERMINFO\fR is set, the compiled
|
|
results are placed there instead of \fB\*d\fR.
|
|
|
|
Total compiled entries cannot exceed 4096 bytes. The name field cannot
|
|
exceed 512 bytes. Terminal names exceeding the maximum alias length
|
|
(32 characters on systems with long filenames, 14 characters otherwise)
|
|
will be truncated to the maximum alias length and a warning message will be printed.
|
|
.SH COMPATIBILITY
|
|
There is some evidence that historic \fBtic\fR implementations treated
|
|
description fields with no whitespace in them as additional aliases or
|
|
short names. This \fBtic\fR does not do that, but it does warn when
|
|
description fields may be treated that way and check them for dangerous
|
|
characters.
|
|
.SH EXTENSIONS
|
|
Unlike the stock SVr4 \fBtic\fR command, this implementation can actually
|
|
compile termcap sources. In fact, entries in terminfo and termcap syntax can
|
|
be mixed in a single source file. See \fBterminfo\fR(\*n) for the list of
|
|
termcap names taken to be equivalent to terminfo names.
|
|
|
|
The SVr4 manual pages are not clear on the resolution rules for \fBuse\fR
|
|
capabilities.
|
|
This implementation of \fBtic\fR will find \fBuse\fR targets anywhere
|
|
in the source file, or anywhere in the file tree rooted at \fBTERMINFO\fR (if
|
|
\fBTERMINFO\fR is defined), or in the user's \fI$HOME/.terminfo\fR directory
|
|
(if it exists), or (finally) anywhere in the system's file tree of
|
|
compiled entries.
|
|
|
|
The error messages from this \fBtic\fR have the same format as GNU C
|
|
error messages, and can be parsed by GNU Emacs's compile facility.
