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`. paren_level indent_levelreturnNcDd|_dg|_|jdkDsJyNr)rrtab_lenselfs r__init__zIndenter.__init__ s&C||artokenc#K|jdkDry||jddd}|jd|jd|jzz}||jdkDr?|jj |t j|j||y||jdkrP|jjt j|j||||jdkrP||jdk7rtd|d|jdyw) Nr r  zUnexpected dedent to column z.
