Syntax highlighting on blogs

leave a comment »

Syntax highlighting is always been a desired things on blogs, specially for those who post their code so often on blogs. Not only it adds to the look of the blog but also, it makes the code more readable.  From quite a few days, i was trying to search for something by which i can paste my codes in formatted highlighted form on the blog, but whatever plug-in i found was not integrateable into wordpress free service.

The earlier solutions that came to my mind was taking a snapshot of the code window and post here. But it includes few extra steps for me (taking a snapshopt, croping it and the uploading it) and for reader, they just can’t COPY-PASTE the code if they want to.

highlightSo if you are one of those who are looking for some syntax highlighting thing for your blog, here is some great tool, named Highlight. The tools come with some default styles, including eclipse, emacs and other well know editors. You can configure the style if you wish so and the you can export it in your desired format i.e (html – with inline CSS, RTF, XHTML, LaTeX, SVG, XML etc).  See the below snippet that I formatted/highlighted using the it. it’s pretty clean and easy to incorporate 🙂
