of the pyparsing expressions that caused the exception to be raised.
Parameters:
- exc - exception raised during parsing (need not be a ParseException, in support
of Python exceptions that might be raised in a parse action)
- 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.
Note: the diagnostic output will include string representations of the expressions
that failed to parse. These representations will be more helpful if you use `setName` to
give identifiable names to your expressions. Otherwise they will use the default string
forms, which may be cryptic to read.
explain() is only supported under Python 3.

Define one or more actions to perform when successfully matching parse element definition.
Parse action fn is a callable method with 0-3 arguments, called as ``fn(s, loc, toks)`` ,

- s = the original string being parsed (see note below)
- loc = the location of the matching substring
- toks = a list of the matched tokens, packaged as a :class:`ParseResults` object
If the functions in fns modify the tokens, they can return them as the return
value from fn, and the modified list of tokens will replace the original.
Otherwise, fn does not need to return any value.
If None is passed as the parse action, all previously added parse actions for this
expression are cleared.
Optional keyword arguments:
- callDuringTry = (default= ``False``) indicate if parse action should be run during lookaheads and alternate testing
Note: the default parsing behavior is to expand tabs in the input string
before starting the parsing process. See :class:`parseString for more
information on parsing strings containing ``<TAB>`` s, and suggested
methods to maintain a consistent view of the parsed string, the parse
location, and line and column positions within the parsed string.
Example::
integer = Word(nums)
date_str = integer + '/' + integer + '/' + integer
date_str.parseString("1999/12/31") # -> ['1999', '/', '12', '/', '31']

ParserElement.enablePackrat | (cache_size_limit=128) | Enables "packrat" parsing, which adds memoizing to the parsing logic.
Repeated parse attempts at the same string location (which happens
often in many complex grammars) can immediately return a cached value,
instead of re-executing parsing/validating code. Memoizing is done of
both valid results and parsing exceptions.
Parameters:
- cache_size_limit - (default= ``128``) - if an integer value is provided
will limit the size of the packrat cache; if None is passed, then
the cache size will be unbounded; if 0 is passed, the cache will
be effectively disabled.
This speedup may break existing programs that use parse actions that
have side-effects. For this reason, packrat parsing is disabled when
you first import pyparsing. To activate the packrat feature, your
program must call the class method :class:`ParserElement.enablePackrat`.
For best results, call ``enablePackrat()`` immediately after
importing pyparsing.
Example::
from pip._vendor import pyparsing
pyparsing.ParserElement.enablePackrat()
| Enables "packrat" parsing, which adds memoizing to the parsing logic.

ParserElement.parseString | (self, instring, parseAll=False) |
Execute the parse expression with the given string.
This is the main interface to the client code, once the complete
expression has been built.
Returns the parsed data as a :class:`ParseResults` object, which may be
accessed as a list, or as a dict or object with attributes if the given parser
includes results names.
If you want the grammar to require that the entire input string be
successfully parsed, then set ``parseAll`` to True (equivalent to ending
the grammar with ``StringEnd()``).
Note: ``parseString`` implicitly calls ``expandtabs()`` on the input string,
in order to report proper column numbers in parse actions.
If the input string contains tabs and
the grammar uses parse actions that use the ``loc`` argument to index into the
string being parsed, you can ensure you have a consistent view of the input
string by:
- calling ``parseWithTabs`` on your grammar before calling ``parseString``
(see :class:`parseWithTabs`)
- define your parse action using the full ``(s, loc, toks)`` signature, and
reference the input string using the parse action's ``s`` argument
- explictly expand the tabs in your input string before calling
``parseString``
Example::
Word('a').parseString('aaaaabaaa') # -> ['aaaaa']
Word('a').parseString('aaaaabaaa', parseAll=True) # -> Exception: Expected end of text

action. ``transformString()`` returns the resulting transformed string.
Example::
