LaTeX lexer

[bergwerf]

A minimal TeX equation lexer would be very useful for me. I'm not sure if it's easy to add TeX subscript and fractions to the Lexer though.

I can see how that could be useful, and a minimal TeX lexer supporting just a small subset shouldn't be too hard to implement. Which notations would be important for your use case?

Unfortunately I currently don't have much time to work on this, but might pick it up in the future.
In the meantime - pull requests are welcome :)

The only LaTeX features I often use and that might cost some extra effort to implement are fractions (because there are two {} groups, unlike most functions), and sub/superscript (e.g. \sin{3}^{10} is a power but `A_{10} is a variable).

I found I needed some advanced algebra features as well, so I'm now strongly considering SymPy for my project. It might be a good idea to keep this open though.
Fun fact, SymPy currently also still lacks an official LaTeX parser ;-)
