WordPress Plugin: Prismatic

I’ve been using other plugins to display my code at Perishable Press, Plugin Planet, DigWP, and WP-Mix for years now. The other plugins have done the job, but there are things that I’ve always wanted to change. For example, syntax highlighting. I use syntax highlighting for code snippets at WP-Mix, but not on any of my other sites. So I wanted to combine clean, time-tested code escaping with stylish syntax highlighting. After sharing well over 1,000 code snippets online, I figure it’s finally time to make it happen..

Announcing Prismatic — a plugin that cleanly escapes code snippets and applies syntax-highlighting using either Prism.js or Highlight.js.

Choose your library

Display beautiful code snippets with Prism.js, Highlight.js, or plain code escaping:

• Prism.js – Code escape + syntax highlight using Prism.js
• Highlight.js – Code escape + syntax highlight using Highlight.js
• Plain Flavor – Code escape without syntax highlight (for custom styles)
