NAME
       tic - the terminfo entry-description compiler

SYNOPSIS
       tic [-1CGILNTUVacfgrstx] [-e names] [-o dir] [-R subset] [-v[n]] [-w[n]] file

DESCRIPTION
       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(3NCURSES).

       The results are normally placed in  the	system	terminfo  directory  /usr/share/terminfo.
       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 /usr/share/terminfo 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 /usr/share/terminfo.

       -1     restricts the output to a single column

       -a     tells  tic to retain commented-out capabilities rather than discarding them.  Capa-
	      bilities 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(1) in that it does not  merely  translate  capability	names,	but  also
	      translates terminfo strings to termcap format.  Capabilities that are not translat-
	      able 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  ter-
	      minfo), 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 equiv-
	      alents.

       -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, new-
	      line,  key_backspace, key_left, and key_down, then attempts to use obsolete termcap
	      capabilities to deduce correct values.  It also normally suppresses output of obso-
	      lete  termcap  capabilities such as bs.  This option forces a more literal transla-
	      tion 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(5) 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 show-
	    ing 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  ter-
	    minfo(5)].	 Each  description in the file describes the capabilities of a particular
	    terminal.

       The debug flag levels are as follows:

       1      Names of files created and linked

       2      Information related to the ``use'' facility

       3      Statistics from the hashing algorithm

       5      String-table memory allocations

       7      Entries into the string-table

       8      List of tokens encountered by scanner

       9      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(5).   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 /usr/share/terminfo 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  /usr/share/terminfo.)   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  capa-
       bilities  in entry_name_2 must also appear in entry_name_1 before use= for these capabili-
       ties to be canceled in entry_name_1.

       If the environment variable TERMINFO is set, the compiled results are placed there instead
       of /usr/share/terminfo.

       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.

COMPATIBILITY
       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  dan-
       gerous characters.

EXTENSIONS
       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(5)  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/.ter-
       minfo  directory  (if  it exists), or (finally) anywhere in the system's file tree of com-
       piled 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 sup-
       ported 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.

FILES
       /usr/share/terminfo/?/*
	    Compiled terminal description database.
