Ultraviolet gives new life to Syntax highlighting
Posted by Michael on February 5, 2009 in General, Programming
I am tired of Google’s Syntax highlighter. If I accidentally switch to Visual mode in the editor and do some edits and switch back to HTML mode, then I lose the class=”code” moniker and I have to go through the entire post and fix.
Another drawback I have with Google Syntax highlighter is that the page renders without highlighting and then all the code listings change to syntax highlighted text a few moments later.
Introducing Ultraviolet, a syntax highlighter supporting over 50 syntaxes and any TextMate theme. Ultraviolet is based on Oniguruma, a regular expression library that comes standard with Ruby 1.9. Ultraviolet requires a little more effort for me to cut and paste, but I am definitely much happier with the end results and Wordpress no longer mungs my posts. Only real complaint I have is that I can’t read the posted code inline in HTML format (but I can read it in Visual mode!).
