tic - the terminfo entry-description compiler
tic [-[-e names] [-o dir] [-R subset] [-v[n]] [-w[n]] file
The command tic translates a terminfo file from source format
into compiled format. The compiled format is necessary for use with the
library routines in ncurses(3X)
.
The results are normally placed in the
system terminfo directory . There are two ways to change this behavior.
First,
you may override the system default by setting the variable TERMINFO in
your shell environment to a valid (existing) directory name.
Secondly, if
tic cannot get access to or your TERMINFO directory, it looks for the
directory $HOME/.terminfo; if that directory exists, the entry is placed
there.
Libraries that read terminfo entries are expected to check for a
TERMINFO directory first, look at $HOME/.terminfo if TERMINFO is not set,
and finally look in .
- -1
- restricts the output to a single column
- -a
- tells
tic to retain commented-out capabilities rather than discarding them. Capabilities
are commented by prefixing them with a period. This sets the -x option, because
it treats the commented-out entries as user-defined names. If the source is
termcap, accept the 2-character names required by version 6. Otherwise these
are ignored.
- -C
- Force source translation to termcap format. Note: this differs
from the -C option of infocmp(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.
- -c
- tells tic to only check file
for errors, including syntax problems and bad use links. If you specify
-C (-I) 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.
- -e names
- 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.)
- -f
- Display complex terminfo strings which contain if/then/else/endif
expressions indented for readability.
- -G
- Display constant literals in decimal
form rather than their character equivalents.
- -g
- Display constant character
literals in quoted form rather than their decimal equivalents.
- -I
- Force source
translation to terminfo format.
- -L
- Force source translation to terminfo format
using the long C variable names listed in <term.h>
- -N
- Disable smart defaults.
Normally, when translating from termcap to terminfo, the compiler makes
a number of assumptions about the defaults of string capabilities reset1_string,
carriage_return, cursor_left, cursor_down, scroll_forward, tab, newline,
key_backspace, key_left, and key_down, then attempts to use obsolete termcap
capabilities to deduce correct values. It also normally suppresses output
of obsolete termcap capabilities such as bs. This option forces a more literal
translation that also preserves the obsolete capabilities.
- -odir
- Write compiled
entries to given directory. Overrides the TERMINFO environment variable.
- -Rsubset
- 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 do not 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 terminfo() for
details.
- -r
- 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
through version 1.3 or BSD termcap through 4.3BSD) that does not handle multiple
tc capabilities per entry.
- -s
- Summarize the compile by showing the directory
into which entries are written, and the number of entries which are compiled.
- -T
- 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).
- -t
- tells tic to discard commented-out
capabilities. Normally when translating from terminfo to termcap, untranslatable
capabilities are commented-out.
- -U
- tells tic to not post-process the data after
parsing the source file. Normally, it infers data which is commonly missing
in older terminfo data, or in termcaps.
- -V
- reports the version of ncurses
which was used in this program, and exits.
- -vn
- specifies that (verbose) output
be written to standard error trace information showing tic’s progress. The
optional parameter n is a number from 1 to 10, inclusive, indicating the
desired level of detail of information. If n is omitted, the default level
is 1. If n is specified and greater than 1, the level of detail is increased.
- -wn
- specifies the width of the output. The parameter is optional. If it is
omitted, it defaults to 60.
- -x
- Treat unknown capabilities as user-defined.
That is, if you supply a capability name which tic does not recognize,
it will infer its type (boolean, number or string) from the syntax and
make an extended table entry for that. User-defined capability strings whose
name begins with ‘‘k’’ are treated as function keys.
- file
- contains one or more
terminfo terminal descriptions in source format [see terminfo()]. Each description
in the file describes the capabilities of a particular terminal.
The debug
flag levels are as follows:
- Names of files created and linked
- Information
related to the ‘‘use’’ facility
- Statistics from the hashing algorithm
- String-table
memory allocations
- Entries into the string-table
- List of tokens encountered
by scanner
- All values computed in construction of the hash table
If the
debug level n is not given, it is taken to be one.
All but one of the capabilities
recognized by tic are documented in terminfo(). The exception is the use
capability.
When a use=entry-name field is discovered in a terminal entry
currently being compiled, tic reads in the binary from to complete the
entry. (Entries created from file will be used first. If the environment
variable TERMINFO is set, that directory is searched instead of .) tic
duplicates the capabilities in entry-name for the current entry, with the
exception of those capabilities that explicitly are defined in the current
entry.
When an entry, e.g., entry_name_1, contains a use=entry_name_2 field,
any canceled capabilities in entry_name_2 must also appear in entry_name_1
before use= for these capabilities to be canceled in entry_name_1.
If the
environment variable TERMINFO is set, the compiled results are placed there
instead of .
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.
There is some evidence that historic tic implementations
treated description fields with no whitespace in them as additional aliases
or short names. This tic does not do that, but it does warn when description
fields may be treated that way and check them for dangerous characters.
Unlike the stock SVr4 tic 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 terminfo() 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 use capabilities. This implementation
of tic will find use targets anywhere in the source file, or anywhere in
the file tree rooted at TERMINFO (if TERMINFO is defined), or in the user’s
$HOME/.terminfo directory (if it exists), or (finally) anywhere in the system’s
file tree of compiled entries.
The error messages from this tic have the
same format as GNU C error messages, and can be parsed by GNU Emacs’s compile
facility.
The -C, -G, -I, -N, -R, -T, -V, -a, -e, -f, -g, -o, -r, -s, -t and -x options
are not supported under SVr4. The SVr4 -c mode does not report bad use links.
System V does not compile entries to or read entries from your $HOME/.terminfo
directory unless TERMINFO is explicitly set to it.
