NAME
       tic - the terminfo entry-description compiler

SYNOPSIS
       tic [-v[n]] [-w[n]] [-1hcpICNRrsTu] [-e names] [-o dir] 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
       /usr/local/share/terminfo.  There are two ways to change this behavior.

       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 /usr/local/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 /usr/local/share/terminfo.

       -h     Print help message and exit.

       -c     specifies	 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.

       -vn    specifies that (verbose) output be  written  to  standard	 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 TER‐
	      MINFO environment variable.

       -wn    specifies the width of the output.

       -1     restricts the output to a single column

       -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).

       -I     Force source translation to terminfo format.

       -L     Force  source  translation  to  terminfo format using the long C
	      variable names listed in <term.h>

       -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.

       -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.

       -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  don't  support the full set of SVR4/XSI Curses ter‐
	      minfo; and outright broken ports like AIX 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 up to version 1.3 or BSD termcap up
	      to  4.3BSD)  that	 doesn't  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.

       -e     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.)

       file   contains one or more terminfo terminal  descriptions  in	source
	      format   [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 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/local/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/local/share/terminfo.)  tic duplicates the capabilities
       in entry-name for the current entry, with the exception of those	 capa‐
       bilities 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 /usr/local/share/terminfo.

       Total compiled entries cannot exceed 4096 bytes.	 The name field cannot
       exceed 128 bytes.  Terminal names exceeding 14 characters will be trun‐
       cated to 14 characters 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 -o, -I, -C, -N, -R, -h, -e, -T, -r and -s 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.

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