yikes! Sorry about that. It seems that even in plain-text mode copy-pasted text gets mangled by yahoo. That happens *after* sending the mail. Here is the correctly indented code (website-->notepad-->yahoo):


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

class IniLexer(RegexLexer):
    name = 'INI'
    aliases = ['ini', 'cfg']
    filenames = ['*.ini', '*.cfg']

    tokens = {
        'root': [
            (r'\s+', Text),
            (r';.*?$', Comment),
            (r'\[.*?\]$', Keyword),
            (r'(.*?)(\s*)(=)(\s*)(.*?)$',
             bygroups(Name.Attribute, Text, Operator, Text, String))
        ]
    }
