GitHub Markdown (Full Text)

Markdown syntax with support for GitHub Markdown extensions, like fenced code blocks, and ~strikethrough~.

This is an alternate version of the built-in version of the GitHub Markdown syntax changed to evaluated the full text of the draft with all changes. This can slow performance in some cases, but if you often use longer drafts with code blocks, or similar extended block elements, it avoids the case where changes in longer drafts can lose syntax formatting for some text temporarily.
