tic



SYNOPSIS

       tic  [-1CGILNTVacfgrstx]  [-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 nec­
       essary   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/ter­
       minfo.

       -1     restricts the output to a single column

       -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     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 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.
              ability.

       -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 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.

       -odir  Write  compiled  entries to given directory.  Over­
              rides 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 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.

       -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 multi­
              ple 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,
              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.

       -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  the debug level 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
       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,  -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 explic­
       itly set to it.


FILES
