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 com‐
       piled  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
       /opt/freeware/share/terminfo.  There are two ways to change this behav‐
       ior.

       First, you may override the system default by setting the variable TER‐
       MINFO in your shell environment to a valid (existing) directory name.

       Secondly,  if  tic cannot get access to /opt/freeware/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 TER‐
       MINFO directory first, look at $HOME/.terminfo if TERMINFO is not  set,
       and finally look in /opt/freeware/share/terminfo.

       -1     restricts the output to a single column

       -a     tells  tic to retain commented-out capabilities rather than dis‐
	      carding them.  Capabilities are commented by prefixing them with
	      a	 period.   This sets the -x option, because it treats the com‐
	      mented-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 prob‐
	      lems 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 com‐
	      piled, 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,	  car‐
	      riage_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  TER‐
	      MINFO 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 ter‐
	      minfo; 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 capabili‐
	      ties) 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 com‐
	      piled.

       -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  ter‐
	      minfo).

       -t     tells  tic to discard commented-out capabilities.	 Normally when
	      translating from terminfo to termcap,  untranslatable  capabili‐
	      ties 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  sup‐
	    ply	 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 for‐
	    mat [see terminfo(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  /opt/freeware/share/ter‐
       minfo  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 /opt/freeware/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  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 /opt/freeware/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 descrip‐
       tion fields may be treated that way and check them for dangerous	 char‐
       acters.

EXTENSIONS
       Unlike  the  stock  SVr4	 tic command, this implementation can actually
       compile termcap sources.	 In fact, entries in terminfo and termcap syn‐
       tax 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 any‐
       where in the source file, or anywhere in the file tree rooted  at  TER‐
       MINFO (if TERMINFO is defined), or in the user's $HOME/.terminfo direc‐
       tory (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.
