Font-locking code blocks

[xiongtx]

Expected behavior

There should be a way to font-lock code blocks for supported languages, similar to Orgmode's org-src-font-lock-fontify-block.

This may be particular to gfm-mode.

Actual behavior

There is no such feature.

Steps to reproduce (recipe)

N/A

Backtraces if some (M-x toggle-debug-on-error)

N/A

Versions of markdown-mode, Emacs, OS, etc.

• markdown-mode: 2.1
• Emacs: 25.1.50.1
• OS: Darwin C02RW05YFVH6 15.6.0

I've actually come looking for exactly this feature.

This is extremly simple to implement, I've done it for sphinx: https://github.com/Fuco1/sphinx-mode/blob/master/sphinx-src.el The code could be copied 1:1 or extracted as an extra dependency.

Thanks for the pointer @Fuco1! I have something working and hope to push it soon...

This is in the master branch now. The main commit is 76ccd82. It's disabled by default, but set markdown-fontify-code-blocks-natively to t and reload to see it. I'll add a toggle key and command soon...

Update:

• Toggle added in 7e37293, bound to C-c C-x C-f.
• Typo in comment found by @xiongtx fixed in 1d77e06.
• Compatibility with Emacs < 24.4 fixed in ef314c8 and 5570cfc.

I closed this accidentally, but I'll leave it that way for now. Let me know if you have any other comments or if anything doesn't work right.

Update: With 740bd6a, native fontification works for tilde-fenced code blocks too.
