Comment forms allow some HTML, this plugin extends that to let users type in <a href="http://daringfireball.net/projects/markdown/" rel="nofollow ugc">Markdown</a> and have it automatically converted to HTML. It also extends Markdown with a couple features made popular <a href="https://github.com/github/github-flavored-markdown" rel="nofollow ugc">by GitHub</a>. Conversion from Markdown to HTML is completely automated and doesn’t require anything on the commenter’s part.
The feature additions from GitHub are:
<ul>
<li>Single linebreaks are treated as new paragraphs</li>
<li>Code “fencing” with three backticks (“`)</li>
</ul>
Two notable features from GitHub’s Markdown implementation are missing:
<ul>
<li>To do lists: Doing these well would require some front end interaction, which I decided is outside the scope of this plugin at least for now</li>
<li>Repository autolinking (e.g. comments, issues, etc): These seemed a little too GitHub-specific.</li>
</ul>
GitHub-Flavored Markdown Comments is developed, unsurprisingly, <a href="https://github.com/evansolomon/wp-github-flavored-markdown-comments" rel="nofollow ugc">on GitHub</a>.

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
