Syntax highlighting in GFM code blocks

[ihodes]

Is this best supported through markdown-mode or through something like multi-mode highlighting?

[jrblevin]

There are a few such modes already, including mmm-mode and polymode.

For a while, I was using mmm-mode configured as described here: http://jblevins.org/log/mmm. I don't do this any more, though, and so I haven't followed these packages recently.

Awesome, I hadn't seen polymode. That'll work for me! Thank you :)

Using polymode, it's trivial to highlight fenced code blocks in markdown-mode. All I needed to do was add the following to Emacs config:

(require 'markdown-mode)
(require 'poly-markdown)
(add-to-list 'auto-mode-alist '("\\.md\\'" . poly-markdown-mode))

Docs I used:

Built-in support is in master now. See custom variable markdown-fontify-code-blocks-natively and interactive function markdown-toggle-fontify-code-blocks-natively (C-c C-x C-f).
