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:: # an expression to parse 3 integers expr = pp.Word(pp.nums) * 3 try: # a failing parse - the third integer is prefixed with "A" 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`` )rA)rr8r r rexplains'zParseBaseException.explain markInputline)rNN)r)N)r)r r r __doc__int__annotations__rWtypingAnyTupleOptional __slots__r staticmethodrA classmethodrDpropertyrrrr*rLsetterrVrXr^r_rr`r r r rrsV     ?    +rc@seZdZdZdS)ParseExceptiona{ Exception thrown when a parse expression doesn't match the input string Example:: integer = Word(nums).set_name("integer") try: integer.parse_string("ABC") except ParseException as pe: print(pe) print(f"column: {pe.column}") prints:: Expected integer (at char 0), (line:1, col:1) column: 1 Nr r r rar r r rrmsrmc@seZdZdZdS)ParseFatalExceptionzu User-throwable exception thrown when inconsistent parse content is found; stops all parsing immediately Nrnr r r rrosroc@seZdZdZdS)ParseSyntaxExceptionz Just like :class:`ParseFatalException`, but thrown internally when an :class:`ErrorStop` ('-' operator) indicates that parsing is to stop immediately because an unbacktrackable syntax error has been found.
