-DESCRIPTION
- The command tic translates a terminfo file from source
+
+ The tic command translates a terminfo file from source
format into compiled format. The compiled format is nec-
- essary for use with the library routines in ncurses(3x).
+ essary for use with the library routines in ncurses(3x).
+
+ As described in term(5), the database may be either a
+ directory tree (one file per terminal entry) or a hashed
+ database (one record per entry). The tic command writes
+ only one type of entry, depending on how it was built:
+
+ o For directory trees, the top-level directory, e.g.,
+ /usr/share/terminfo, specifies the location of the
+ database.
+
+ o For hashed databases, a filename is needed. If the
+ given file is not found by that name, but can be found
+ by adding the suffix ".db", then that is used.
+
+ The default name for the hashed database is the same
+ as the default directory name (only adding a ".db"
+ suffix).
+
+ In either case (directory or hashed database), tic will
+ create the container if it does not exist. For a direc-
+ tory, this would be the "terminfo" leaf, versus a "ter-
+ minfo.db" file.
The results are normally placed in the system terminfo
- directory /usr/share/terminfo. There are two ways to
- change this behavior.
+ database /usr/share/terminfo. The compiled terminal
+ description can be placed in a different terminfo data-
+ base. There are two ways to achieve this:
- First, you may override the system default by setting the
- variable TERMINFO in your shell environment to a valid
- (existing) directory name.
+ o First, you may override the system default either by
+ using the -o option, or by setting the variable TER-
+ MINFO in your shell environment to a valid database
+ location.
- Secondly, if tic cannot get access to /usr/share/terminfo
- or your TERMINFO directory, it looks for the directory
- $HOME/.terminfo; if that directory exists, the entry is
- placed there.
+ o Secondly, if tic cannot write in /usr/share/terminfo
+ or the location specified using your TERMINFO vari-
+ able, it looks for the directory $HOME/.terminfo (or
+ hashed database $HOME/.terminfo.db); if that location
+ 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 /usr/share/ter-
- minfo.
+ in succession
- -a tells tic to retain commented-out capabilities
- rather than discarding them. Capabilities are com-
- mented by prefixing them with a period. This sets
- the -x option, because it treats the commented-out
- entries as user-defined names.
+ o a location specified with the TERMINFO environment
+ variable,
- -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 warn-
- ings 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.
-
- -vn specifies that (verbose) output be written to stan-
- dard error trace information showing tic's
- progress. The optional integer 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.
-
- -odir Write compiled entries to given directory.
- Overrides the TERMINFO environment variable.
+ o $HOME/.terminfo,
+
+ o directories listed in the TERMINFO_DIRS environment
+ variable,
+
+ o a compiled-in list of directories
+ (/usr/local/ncurses/share/terminfo:/usr/share/ter-
+ minfo), and
- -wn specifies the width of the output.
+ o the system terminfo database (/usr/share/terminfo).

- -C Force source translation to termcap format. Note:
- this differs from the -C option of infocmp(1m) in
+ -a tells tic to retain commented-out capabilities
+ rather than discarding them. Capabilities are com-
+ mented 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
+ 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.
+ left in the entry under their terminfo names but
+ commented out with two preceding dots. The actual
+ format used incorporates some improvements for
+ escaped characters from terminfo format. For a
+ stricter BSD-compatible translation, add the -K
+ option.
+
+ If this is combined with -c, tic makes additional
+ checks to report cases where the terminfo values do
+ not have an exact equivalent in termcap form. For
+ example:
+
+ o sgr usually will not convert, because termcap
+ lacks the ability to work with more than two
+ parameters, and because termcap lacks many of
+ the arithmetic/logical operators used in ter-
+ minfo.
+
+ o capabilities with more than one delay or with
+ delays before the end of the string will not
+ convert completely.
+
+ -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 warn-
+ ings about entries which, after use resolution, are
+ more than 1023 (4096) bytes long. Due to a fixed
+ buffer length in older termcap libraries, as well
+ as buggy checking for the buffer length (and a doc-
+ umented limit in terminfo), these entries may cause
+ core dumps with other implementations.
+
+ tic checks string capabilities to ensure that those
+ with parameters will be valid expressions. It does
+ this check only for the predefined string capabili-
+ ties; those which are defined with the -x option
+ are ignored.
+
+ -D tells tic to print the database locations that it
+ knows about, and exit. The first location shown is
+ the one to which it would write compiled terminal
+ descriptions. If tic is not able to find a
+ writable database location according to the rules
+ summarized above, it will print a diagnostic and
+ exit with an error rather than printing a list of
+ database locations.
+
+ -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 con-
+ taining the list if it contains a '/'. (Note:
+ depending on how tic was compiled, this option may
+ require -I or -C.)
- -G Display constant literals in decimal form rather
+ -f Display complex terminfo strings which contain
