Especially if you need something more than "JavaScript, Java, Ruby, Python, Go, and C" - pygments has a list of supported languages a tiny bit longer than that: http://pygments.org/languages/ http://pygments.org/languages/ True, it takes some time to highlight some files - for example 5k loc long Racket files or very long XML/HTML files - but it supports all the languages I use (or used or may use in the future), while this tool supports only one of the languages I use on a daily basis.
