With Pastacode, you can easily add code into your posts with the awesome PrismJs coloration library. 
You can insert source code into the post editor, wrinting it directly in the editor (using a gutenberg bloc or classic editor), from a file, or from webservices like GitHub, Gitlab, Gist, Pastebin, BitBucket or BitBucket snippets. Webservices responses are cached in order to avoid too many HTTP requests. 
It also work in comments and bbPress topics and replies.
Don’t worry about posts updates while upgrading codes!
Pastacode allows to enhance your snippets using PrismJs plugins (highlightning lines, link functions…).

I've been waiting for years for such a plugin! Pastacode is easy to use, well coded and looks gorgeous with any WordPress theme. Keep going!



Best plugin to embed code

Just started using this plugin, but I'm quickly becoming a big fan. Not only does this allow you to embed & highlight the normal stuff, but it will also fetch and embed directly from a github/bitbucket repo. Awesome work!

Great code embed & syntax highlighting plugin
