If this method returns ``0`` it won't highlight it in any case, if it returns ``1`` highlighting with this lexer is guaranteed. The `LexerMeta` metaclass automatically wraps this function so that it works like a static method (no ``self`` or ``cls`` parameter) and the return value is automatically converted to `float`. If the return value is an object that is boolean `False` it's the same as if the return values was ``0.0``.
