LaTeX encoder

[Quintus]

Hi,

I was wondering why CodeRay has no LaTeX encoder, so I made one :-). I did a few tests with it, and it seemed ok, but I’ve not yet thrown really obfuscated code on it.

The large string in the file is a LaTeX preamble snippet that needs to be included (e.g. by \include). This preamble snippet allows you to customize the coloring of the result code. Currently, it uses mostly plain black (thus the highlighting isn’t that detailed), but it allows for nearly the same amount of customisation as CodeRay’s CSS classes for the HTML highlighter do.

The highlighter supports line numbers and whitespace visualisation.

I recommend to use this with LuaLaTeX. I’ve tested it with PDFLaTeX though, and as long as you have plain old ASCII sourcecode files (including comments!), it works with it. The show_whitespace option definitely requires a Unicode-aware TeX engine such as Luatex as it uses Unicode characters for replacement.

This probably implements #50. I’ve written this completely from scratch, though.

Vale,
Quintus

Yay, this breaks GitHub’s highlighter completely. A shame they aren’t using CodeRay! 🐸

Do we actually need this?

[Quintus]

Emacs adds this line automatically when it discovers UTF-8 characters in the source file (even if they’re in the comments). The line is not “needed” in that sense thus.

Wow, this is awesome! I'm not using LaTeX anymore, so I would need a bit of time to test it. Can we add some tests? Preferrably even one that actually runs the output through tex…

[Quintus]

I think I should be able to add some tests, yes. It will take me some time, though, because I’m busy with different things right now.

@korny is that correct that you invited me to @rubychan? I’m just doing PRs on CodeRay occasionally, but I can’t maintain it as such. https://github.com/Secretchronicles/TSC eats up most of my free time.

Yes I did :-) You earned it. You don't have to use it, but it feels right to me that you have a commit bit, too.

Ok thank you! I feel honoured.

Why hasn't this been merged? Are there other ways to display LaTeX code within Coderay?

[Quintus]

I suppose it hasn't been merged because neither me nor korny are actively working on CodeRay...
