It keeps track of the current indentation, as well as the current level of parentheses. Inside parentheses, the indentation is ignored, and no indent/dedent tokens get generated. Note: This is an abstract class. To use it, inherit and implement all its abstract methods: - tab_len - NL_type - OPEN_PAREN_types, CLOSE_PAREN_types - INDENT_type, DEDENT_type See also: the ``postlex`` option in `Lark`.
