Used as a base class for the following exceptions: - ``UnexpectedCharacters``: The lexer encountered an unexpected string - ``UnexpectedToken``: The parser received an unexpected token - ``UnexpectedEOF``: The parser expected a token, but the input ended After catching one of these exceptions, you may call the following helper methods to create a nicer error message. linecolumnNstaterinteractive_parsertextspanreturnc|jJ||j}t||z d}||z}t|tsX|||j ddd}|||j ddd}||zdzdt |jzzdzS|||j ddd}|||j ddd}||zdzdt |jzzd zjd d S) aReturns a pretty string pinpointing the error in the text, with span amount of context characters around it.

Given a parser instance and a dictionary mapping some label with some malformed syntax examples, it'll return the label for the example that bests matches the current error. The function will iterate the dictionary until it finds a matching error, and return the corresponding value. For an example usage, see `examples/error_reporting_lalr.py` Parameters: parse_fn: parse function (usually ``lark_instance.parse``) examples: dictionary of ``{'example_string': value}``. use_accepts: Recommended to keep this as ``use_accepts=True``.
