custom pygments lexers: regex

the container should support custom lexers for pygments. they can be installed by copying the lexer files to /usr/lib/python3.x/site-packages/pygments/lexers and running python _mapping.py in that folder.

colin suggested a regex lexer from here:

from pygments.lexer import RegexLexer, bygroups
from pygments.token import *

__all__ = ['regexLexer']

class regexLexer(RegexLexer):
    name = 'regex'
    aliases = ['regex']
    filenames = []

    tokens = {
        'root': [
            (r'\w+', Name),
            (r'\d+', Number),
            (r'[\s\,\:\-\"\']+', Text),
            (r'[\$\^]', Token),
            (r'[\+\*\.\?]', Operator),
            (r'(\()([\?\<\>\!\=\:]{2,3}.+?)(\))', bygroups(Keyword.Namespace, Name.Function, Keyword.Namespace)),
            (r'(\()(\?\#.+?)(\))', bygroups(Comment, Comment, Comment)),
            (r'[\(\)]', Keyword.Namespace),
            (r'[\[\]]', Name.Class),
            (r'\\\w', Keyword),
            (r'[\{\}]', Operator),
        ],
    }

todo:

[x] test the lexer without the container (no point in adding it if it doesn't work as expected) -> colin
[ ] create a new directory for lexers and load them into their target folders
[ ] figure out how to determine python version (maybe pin to specific minor version)
