Enable Github-flavoured Markdown

[eblade]

Given how I assume this app is built (not too familiar with Electron, but it looks web-ish to me), would it be possible to use for instance this renderer marked to enable Github-flavoured Markdown (GFM). The main feature for me would be syntax highlighting for a number of languages.

We're already using marked, so I think we just need to enable the gfm option 👍

+1 on syntax highlighting support.

Are there plans to also enable Markdown for the OSX application?

According to the readme and the code, marked has gfm enabled by default. https://github.com/chjj/marked/blob/master/lib/marked.js#L1242

To get syntax highlighting, you need to add another library like https://github.com/isagalaev/highlight.js

Will be resolved when #309 merges.

Looking forward to it!

GFM seems to work for me by wrapping code in ``` backticks.

This displays fine in the electron based client preview but breaks in the web version preview.

Can we get the web version to have parity with this feature?

I've previously been wrapping code in <pre> </pre>

A request in #3241877-t for Fountain script (https://fountain.io/), which is a markup language for writers.

This should have been fixed in the rollout of the showdown renderer in #577.
