Syntax highlighting

Syntax Highlighting, started in #78 (closed).

mentioned in issue #78 (closed)

unmarked as a Work In Progress

changed the description

Not a major issue, but Pygments should get added to requirements-to-freeze.txt. It's currently getting installed by something else as a dependency, but if we ever ended up removing that "parent" package (whatever it is) that would cause the syntax highlighting to break since Pygments would no longer get installed. Adding it to requirements-to-freeze.txt shows that it's a package we specifically need to install.

Thanks, this looks quite good, just a few things that will need updating.

I'm finished reviewing for now, let me know if you need help with anything or when you're ready for review again.

To have different highlighting for different themes, you'd need to put it inside the _themes.scss file: https://gitlab.com/tildes/tildes/blob/master/tildes/scss/_themes.scss

You could probably have it defined as a mixin in a separate file and just include it here, so that the huge block of styles doesn't need to be inside the _themes.scss file itself. I don't know if you want to try to set that up, but I can just do it in a follow-up commit if you want (switching to Solarized light/dark highlighting). If you do want to try, here are Pygments styles for light and dark: https://gist.github.com/nicolashery/5765395
