Luckily, I remembered <a href=\"http:\/\/pygments.org\/\">Pygmentize<\/a> was pretty handy when <a href=\"http:\/\/scott.sherrillmix.com\/blog\/programmer\/displaying-code-in-latex\/\">syntax highlighting in LaTeX<\/a> so I wondered if they had an equivalent output for terminal. It turns out they do (in standard or 256 color no less) so in a couple minutes I had a really short script for highlighting code at the terminal saved it to <code>bin\/ccat<\/code> and was ready to go. Pygmentize really is impressive. Here&#8217;s the script if anyone else is looking to do the same:\n\n[bash]\n#!\/bin\/bash\nif [ ! -t 0 ];then\nfile=\/dev\/stdin\nelif [ -f $1 ];then\nfile=$1\nelse\necho &#8220;Usage: $0 code.c&#8221;\necho &#8220;or e.g. head code.c|$0&#8221;\nexit 1\nfi\npygmentize -f terminal -g $file\n[\/bash]\n\nIt just looks for stdin and if it doesn&#8217;t find it it looks for a file name or takes direct input. Obviously it requires Pygmentize (which is really <a href=\"http:\/\/pygments.org\/download\/\">easy to install<\/a> if you already have Python).","protected":false},"excerpt":{"rendered":"I was just quickly flipping through code on a terminal and got to thinking that it would be pretty handy to be able to syntax highlight when using head or grep without having to open an editor.
