Using VIM as a syntax highlighting engine from Ruby
You can use VIM as a syntax highlighting engine for code fragments in your blogs etc. The below code snippet works sort of, but it is slow for me. Not sure at the moment whether it is VIM or something else. Perhapps others can try it out and suggest speed or other improvments.
1 2 def vimsyn(text, filetype) 3 synfile = Tempfile.new('synfile') 4 synfile.close 5 codefile = Tempfile.new('codefile') 6 codefile << text 7 codefile.close 8 9 # filetype="matlab" 10 11 expr = %Q%/usr/local/bin/vim -f -n -X -e -s -c \ 12 "set filetype=#{filetpe}" \ 13 -c "syntax on" \ 14 -c "set background=dark" \ 15 -c "let html_use_css=1" \ 16 -c "run syntax/2html.vim" \ 17 -c "wq! #{synfile.path}" -c "q" \ 18 #{codefile.path}% 19 20 `#{expr}` 21 html = IO.readlines(synfile.path).join 22 body = html.match(/<body.*<\/body>/m)[0] 23 css = html.match(/<style.*<\/style>/m)[0] 24 css.gsub!(/pre/,'pre.code') 25 css.gsub!(/^body.*$/,'') 26 body.gsub!(/^<body/,'<div') 27 body.gsub!(/<\/body>/,'<div>') 28 body.gsub!(/<pre>/,'<pre class=code>') 29 30 return css+body 31 end
