A Pygments lexer for Maxima (CAS) code

A Lexer for pygments that handles how Maxima (a Computer Algebra System) code is highlighted.

This package based on the asymptote lexer which is also a good option!

Installation

You should be easilly install the package using the command (This package obviously depends on pygments):

$ sudo pip install maximalexer

The package contains a basic test file that you can process:

$ pygmentize -f html -O full -o /tmp/example.html tests/examplefiles/basic.mac
$ firefox /tmp/example.html

Usage

Just like any other pygments lexer, you can highlight Maxima code (not lisp) using pygmentize command, minted latex package, jekyll, and so on.

maximalexer's Issues

Inequality operator is not recognized

Hi,

I have come across an issue with maximalexer. The inequality operator is not recognized as such. For example, consider the following input:

(%i10) M:matrix([1,2],[3,4]);
                                   [ 1  2 ]
(%o10)                             [      ]
                                   [ 3  4 ]
(%i11) determinant(M);
(%o11)                                - 2
(%i12) is(determinant(M)#0);
(%o12)                               true

The final query asks “is the determinant of M not equal to 0”. I am using maximalexer with CTAN's minted. Minted generates the following output (to be used by LaTeχ):

\PYG{k+kt}{is}\PYG{p}{(}\PYG{k+kt}{determinant}\PYG{p}{(}\PYG{n}{M}\PYG{p}{)}\PYG{err}{\PYGZsh{}}\PYG{l+m+mi}{0}\PYG{p}{);;}

Recognize that \PYG{err} indicates an error even though the syntax was correct.
