this ruby script uses vim to syntax highlight __any__ source code (fortran, ocaml, idl, etc) to html:

   #!/usr/bin/env ruby
   require 'tempfile'
   $VERBOSE=nil
   STDERR.reopen(Tempfile::new($$)) unless STDIN.tty?

   fin = ARGV.shift
   fout = ARGV.shift

   fin = ((fin.nil? or fin == '-') ? STDIN : open(fin))
   fout = ((fout.nil? or fout == '-') ? STDOUT : open(fout,'w+'))

   ts = Tempfile::new($$), Tempfile::new($$)
   ts[0].write fin.read
   ts.each{|t| t.close}
   command = %Q( vim -f +'syn on' +'set filetype=ruby' +'set background=light' +'run! syntax/2html.vim' +'w! #{ ts[1].path }' +'qa!' - < #{ ts[0].path } > /dev/null 2>&1 )
   system command
   ts.each{|t| t.open; t.rewind}
   fout.write(ts[1].read)
   ts.each{|t| t.close!}
