## NAME

           tic - the terminfo entry-description compiler

## SYNOPSIS

           tic  [-1CINRTVacfrsx]  [-e names] [-o dir] [-v[n]] [-w[n]]
           file

## DESCRIPTION

           The command tic 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).

           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/ter-
           minfo.

           -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.

           -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.

           -wn    specifies the width of the output.

           -1     restricts the output to a single column

           -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.

           -G     Display constant literals in  decimal  form  rather
                  than their character 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 num-
                  ber of assumptions about  the  defaults  of  string
                  capabilities  reset1_string,  carriage_return, cur-
                  sor_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 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 terminfo; and out-
                  right 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.

           -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).

           -V     reports the version of ncurses which  was  used  in
                  this program, and exits.

           -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 up to version 1.3 or BSD term-
                  cap up to 4.3BSD) that doesn't handle  multiple  tc
                  capabilities per entry.

           -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 con-
                  taining  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  read-
                  ability.

           -g     Display  constant character literals in quoted form
                  rather than their decimal equivalents.

           -s     Summarize the compile by showing the directory into
                  which  entries  are  written,  and  the  number  of
                  entries which are compiled.

           -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.

           file   contains one or more terminfo terminal descriptions
                  in  source format [see terminfo(5)].  Each descrip-
                  tion 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 doc-
           umented in terminfo(5).  The exception is the use capabil-
           ity.

           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 capa-
           bilities 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 /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 dangerous 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 any-
           where  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
           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 explic-
           itly set to it.
