Parameters: - depth (default=16) - number of levels back in the stack trace to list expression and function names; if None, the full stack trace names will be listed; if 0, only the failing input line, marker, and exception string will be shown Returns a multi-line string listing the ParserElements and/or function names in the exception's stack trace. Example:: expr = pp.Word(pp.nums) * 3 try: expr.parse_string("123 456 A789") except pp.ParseException as pe: print(pe.explain(depth=0)) prints:: 123 456 A789 ^ ParseException: Expected W:(0-9), found 'A' (at char 8), (line:1, col:9) Note: the diagnostic output will include string representations of the expressions that failed to parse. These representations will be more helpful if you use `set_name` to give identifiable names to your expressions. Otherwise they will use the default string forms, which may be cryptic to read. Note: pyparsing's default truncation of exception tracebacks may also truncate the stack of expressions that are displayed in the ``explain`` output. To get the full listing of parser expressions, you may have to set ``ParserElement.verbose_stacktrace = True`` )rB )r r8 r r r �explain� s %zParseBaseException.explain)r NN)r rV )r r r �__doc__rW �intr r � staticmethodrB � classmethodrE �propertyr r r r) rU rX r^ r_ � markInputliner r r r r s: ��� � A 'r c @ � e Zd ZdZdS )�ParseExceptionaq Exception thrown when a parse expression doesn't match the input string Example:: try: Word(nums).set_name("integer").parse_string("ABC") except ParseException as pe: print(pe) print("column: {}".format(pe.column)) prints:: Expected integer (at char 0), (line:1, col:1) column: 1 N�r r r r` r r r r rg � � rg c @ rf )�ParseFatalExceptionzu User-throwable exception thrown when inconsistent parse content is found; stops all parsing immediately Nrh r r r r rj � ri rj c @ rf )�ParseSyntaxExceptionz� Just like :class:`ParseFatalException`, but thrown internally when an :class:`ErrorStop<And._ErrorStop>` ('-' operator) indicates that parsing is to stop immediately because an unbacktrackable syntax error has been found.
