" Vim syntax file
" Language: FORTH
" Maintainer: Christian V. J. Brüssow <cvjb@cvjb.de>
" Last Change: Sa 14 Jul 2007 21:39:53 CEST
" Filenames: *.fs,*.ft
" URL: http://www.cvjb.de/comp/vim/forth.vim
" $Id$
" The list of keywords is incomplete, compared with the offical ANS
" wordlist. If you use this language, please improve it, and send me
" the patches.
" Many Thanks to...
"
" 2007-07-11:
" Benjamin Krill <ben at codiert dot org> send me a patch
" to highlight space errors.
" You can toggle this feature on through setting the
" flag forth_space_errors in you vimrc. If you have switched it on,
" you can turn off highlighting of trailing spaces in comments by
" setting forth_no_trail_space_error in your vimrc. If you do not want
" the highlighting of a tabulator following a space in comments, you
" can turn this off by setting forth_no_tab_space_error.
"
" 2006-05-25:
" Bill McCarthy <WJMc@...> and Ilya Sher <ilya-vim@...>
" Who found a bug in the ccomment line in 2004!!!
" I'm really very sorry, that it has taken two years to fix that
" in the offical version of this file. Shame on me.
" I think my face will be red the next ten years...
"
" 2006-05-21:
" Thomas E. Vaughan <tevaugha at ball dot com> send me a patch
" for the parenthesis comment word, so words with a trailing
" parenthesis will not start the highlighting for such comments.
"
" 2003-05-10:
" Andrew Gaul <andrew at gaul.org> send me a patch for
" forthOperators.
"
" 2003-04-03:
" Ron Aaron <ron at ronware dot org> made updates for an
" improved Win32Forth support.
"
" 2002-04-22:
" Charles Shattuck <charley at forth dot org> helped me to settle up with the
" binary and hex number highlighting.
"
" 2002-04-20:
" Charles Shattuck <charley at forth dot org> send me some code for correctly
" highlighting char and [char] followed by an opening paren. He also added
" some words for operators, conditionals, and definitions; and added the
" highlighting for s" and c".
"
" 2000-03-28:
" John Providenza <john at probo dot com> made improvements for the
" highlighting of strings, and added the code for highlighting hex numbers.
"
