pyparsing module - Classes and methods to define and execute parsing grammars
=============================================================================

The pyparsing module is an alternative approach to creating and
executing simple grammars, vs. the traditional lex/yacc approach, or the
use of regular expressions.  With pyparsing, you don't need to learn
a new syntax for defining grammars or matching expressions - the parsing
module provides a library of classes that you use to construct the
grammar directly in Python.

Here is a program to parse "Hello, World!" (or any greeting of the form
``"<salutation>, <addressee>!"``), built up using :class:`Word`,
:class:`Literal`, and :class:`And` elements
(the :class:`'+'<ParserElement.__add__>` operators create :class:`And` expressions,
and the strings are auto-converted to :class:`Literal` expressions)::

    from pyparsing import Word, alphas

    # define grammar of a greeting
    greet = Word(alphas) + "," + Word(alphas) + "!"

    hello = "Hello, World!"
    print (hello, "->", greet.parseString(hello))

The program outputs the following::

    Hello, World! -> ['Hello', ',', 'World', '!']

The Python representation of the grammar is quite readable, owing to the
self-explanatory class names, and the use of '+', '|' and '^' operators.

The :class:`ParseResults` object returned from
:class:`ParserElement.parseString` can be
accessed as a nested list, a dictionary, or an object with named
attributes.

The pyparsing module handles some of the problems that are typically
vexing when writing text parsers:

  - extra or missing whitespace (the above program will also handle
    "Hello,World!", "Hello  ,  World  !", etc.)
  - quoted strings
  - embedded comments


Getting Started -
-----------------
Visit the classes :class:`ParserElement` and :class:`ParseResults` to
see the base classes that most other pyparsing
classes inherit from. Use the docstrings for examples of how to:

 - construct literal match expressions from :class:`Literal` and
   :class:`CaselessLiteral` classes
 - construct character word-group expressions using the :class:`Word`
   class
 - see how to create repetitive expressions using :class:`ZeroOrMore`
   and :class:`OneOrMore` classes
 - use :class:`'+'<And>`, :class:`'|'<MatchFirst>`, :class:`'^'<Or>`,
   and :class:`'&'<Each>` operators to combine simple expressions into
   more complex ones
 - associate names with your parsed results using
   :class:`ParserElement.setResultsName`
 - access the parsed data, which is returned as a :class:`ParseResults`
   object
 - find some helpful expression short-cuts like :class:`delimitedList`
   and :class:`oneOf`
 - find more useful common expressions in the :class:`pyparsing_common`

    A cross-version compatibility configuration for pyparsing features that will be
    released in a future version. By setting values in this configuration to True,
    those features can be enabled in prior versions for compatibility development
    and testing.

     - collect_all_And_tokens - flag to enable fix for Issue #63 that fixes erroneous grouping
       of results names when an And expression is nested within an Or or MatchFirst; set to
       True to enable bugfix released in pyparsing 2.3.0, or False to preserve
       pre-2.3.0 handling of named results
Ta
Diagnostic configuration (all default to False)
     - warn_multiple_tokens_in_named_alternation - flag to enable warnings when a results
       name is defined on a MatchFirst or Or expression with one or more And subexpressions
       (only warns if __compat__.collect_all_And_tokens is False)
     - warn_ungrouped_named_tokens_in_collection - flag to enable warnings when a results
       name is defined on a containing expression with ungrouped subexpressions that also
       have results names
     - warn_name_set_on_empty_Forward - flag to enable warnings whan a Forward is defined
       with a results name, but has no contents defined
     - warn_on_multiple_string_args_to_oneof - flag to enable warnings whan oneOf is
       incorrectly called with multiple str arguments
     - enable_debug_on_named_expressions - flag to auto-enable debug on all subsequent
       calls to ParserElement.setName()

        Method to take an exception and translate the Python internal traceback into a list
        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.

        Removes and returns item at specified index (default= ``last``).
        Supports both ``list`` and ``dict`` semantics for ``pop()``. If
        passed no argument or an integer argument, it will use ``list``
        semantics and pop tokens from the list of parsed tokens. If passed
        a non-integer argument (most likely a string), it will use ``dict``
        semantics and pop the corresponding value from any defined results
        names. A second default return value argument is supported, just as in
        ``dict.pop()``.

        Example::

            def remove_first(tokens):
                tokens.pop(0)
            print(OneOrMore(Word(nums)).parseString("0 123 321")) # -> ['0', '123', '321']
            print(OneOrMore(Word(nums)).addParseAction(remove_first).parseString("0 123 321")) # -> ['123', '321']

            label = Word(alphas)
            patt = label("LABEL") + OneOrMore(Word(nums))
            print(patt.parseString("AAB 123 321").dump())

            # Use pop() in a parse action to remove named result (note that corresponding value is not
            # removed from list form of results)
            def remove_LABEL(tokens):
                tokens.pop("LABEL")
                return tokens
            patt.addParseAction(remove_LABEL)
            print(patt.parseString("AAB 123 321").dump())

        prints::

            ['AAB', '123', '321']
            - LABEL: AAB

            ['AAB', '123', '321']

        Make a copy of this :class:`ParserElement`.  Useful for defining
        different parse actions for the same parsing pattern, using copies of
        the original parse element.

        Example::

            integer = Word(nums).setParseAction(lambda toks: int(toks[0]))
            integerK = integer.copy().addParseAction(lambda toks: toks[0] * 1024) + Suppress("K")
            integerM = integer.copy().addParseAction(lambda toks: toks[0] * 1024 * 1024) + Suppress("M")

            print(OneOrMore(integerK | integerM | integer).parseString("5K 100 640K 256M"))

        prints::

            [5120, 100, 655360, 268435456]

        Equivalent form of ``expr.copy()`` is just ``expr()``::

        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)`` ,
        ``fn(loc, toks)`` , ``fn(toks)`` , or just ``fn()`` , where:

        - 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']

            # use parse action to convert to ints at parse time
            integer = Word(nums).setParseAction(lambda toks: int(toks[0]))
            date_str = integer + '/' + integer + '/' + integer

            # note that integer fields are now ints, not strings
            date_str.parseString("1999/12/31")  # -> [1999, '/', 12, '/', 31]

zParserElement.resetCacheécCs8tjs4dt_|dkr t ¡t_nt |¡t_tjt_dS)aÁEnables "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::

               import pyparsing
               pyparsing.ParserElement.enablePackrat()

        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

        Scan the input string for expression matches.  Each match will return the
        matching tokens, start location, and end location.  May be called with optional
        ``maxMatches`` argument, to clip scanning after 'n' matches are found.  If
        ``overlap`` is specified, then overlapping matches will be reported.

        Note that the start and end locations are reported relative to the string
        being parsed.  See :class:`parseString` for more information on parsing
        strings with embedded tabs.

        Example::

        Extension to :class:`scanString`, to modify matching text with modified tokens that may
        be returned from a parse action.  To use ``transformString``, define a grammar and
        attach a parse action to it that modifies the returned token list.
        Invoking ``transformString()`` on a target string will then scan for matches,
        and replace the matched text patterns according to the logic in the parse
        action.  ``transformString()`` returns the resulting transformed string.

        Example::

        Implementation of + operator - returns :class:`And`. Adding strings to a ParserElement
        converts them to :class:`Literal`s by default.

        Example::

            greet = Word(alphas) + "," + Word(alphas) + "!"
            hello = "Hello, World!"
            print (hello, "->", greet.parseString(hello))

        prints::

            Hello, World! -> ['Hello', ',', 'World', '!']

        ``...`` may be used as a parse expression as a short form of :class:`SkipTo`.

            Literal('start') + ... + Literal('end')

        is equivalent to:

            Literal('start') + SkipTo('end')("_skipped*") + Literal('end')

        Note that the skipped text is returned with '_skipped' as a results name,
        and to support having multiple skips in the same parser, the value returned is
        a list of all skipped text.

        Implementation of * operator, allows use of ``expr * 3`` in place of
        ``expr + expr + expr``.  Expressions may also me multiplied by a 2-integer
        tuple, similar to ``{min, max}`` multipliers in regular expressions.  Tuples
        may also include ``None`` as in:
         - ``expr*(n, None)`` or ``expr*(n, )`` is equivalent
              to ``expr*n + ZeroOrMore(expr)``
              (read as "at least n instances of ``expr``")
         - ``expr*(None, n)`` is equivalent to ``expr*(0, n)``
              (read as "0 to n instances of ``expr``")
         - ``expr*(None, None)`` is equivalent to ``ZeroOrMore(expr)``
         - ``expr*(1, None)`` is equivalent to ``OneOrMore(expr)``

        Note that ``expr*(None, n)`` does not raise an exception if
        more than n exprs exist in the input stream; that is,
        ``expr*(None, n)`` does not enforce a maximum number of expr
        occurrences.  If this behavior is desired, then write
        ``expr*(None, n) + ~expr``

        The output shown is that produced by the default debug actions - custom debug actions can be
        specified using :class:`setDebugActions`. Prior to attempting
        to match the ``wd`` expression, the debugging message ``"Match <exprname> at loc <n>(<line>,<col>)"``
        is shown. Then if the parse succeeds, a ``"Matched"`` message is shown, or an ``"Exception raised"``
        message is shown. Also note the use of :class:`setName` to assign a human-readable name to the expression,
        which makes debugging and exception messages easier to understand - for instance, the default
        name created for the :class:`Word` expression without calling ``setName`` is ``"W:(ABCD...)"``.

        Execute the parse expression on a series of test strings, showing each
        test, the parsed results or where the parse failed. Quick and easy way to
        run a parse expression against a list of sample strings.

        Parameters:
         - tests - a list of separate test strings, or a multiline string of test strings
         - parseAll - (default= ``True``) - flag to pass to :class:`parseString` when running tests
         - comment - (default= ``'#'``) - expression for indicating embedded comments in the test
              string; pass None to disable comment filtering
         - fullDump - (default= ``True``) - dump results as list followed by results names in nested outline;
              if False, only dump nested list
         - printResults - (default= ``True``) prints test output to stdout
         - failureTests - (default= ``False``) indicates if these tests are expected to fail parsing
         - postParse - (default= ``None``) optional callback for successful parse results; called as
              `fn(test_string, parse_results)` and returns a string to be added to the test output
         - file - (default=``None``) optional file-like object to which test output will be written;
              if None, will default to ``sys.stdout``

        Returns: a (success, results) tuple, where success indicates that all tests succeeded
        (or failed if ``failureTests`` is True), and the results contain a list of lines of each
        test's output

        Example::

            number_expr = pyparsing_common.number.copy()

            result = number_expr.runTests('''
                # unsigned integer
                100
                # negative integer
                -100
                # float with scientific notation
                6.02e23
                # integer with scientific notation
                1e-12
                ''')
            print("Success" if result[0] else "Failed!")

            result = number_expr.runTests('''
                # stray character
                100Z
                # missing leading digit before '.'
                -.100
                # too many '.'
                3.14.159
                ''', failureTests=True)
            print("Success" if result[0] else "Failed!")

        prints::

            # unsigned integer
            100
            [100]

            # negative integer

            [-100]

            # float with scientific notation
            6.02e23
            [6.02e+23]

            # integer with scientific notation
            1e-12
            [1e-12]

            Success

            # stray character
            100Z
               ^
            FAIL: Expected end of text (at char 3), (line:1, col:4)

            # missing leading digit before '.'
            -.100
            ^
            FAIL: Expected {real number with scientific notation | real number | signed integer} (at char 0), (line:1, col:1)

            # too many '.'
            3.14.159
                ^
            FAIL: Expected end of text (at char 4), (line:1, col:5)

            Success

        Each test string must be on a single line. If you want to test a string that spans multiple
        lines, create a test like this::

            expr.runTest(r"this is a test\n of strings that spans \n 3 lines")

        (Note that this is a raw string literal, you must include the leading 'r'.)

ZS)r.aToken to exactly match a specified string as a keyword, that is,
    it must be immediately followed by a non-keyword character.  Compare
    with :class:`Literal`:

     - ``Literal("if")`` will match the leading ``'if'`` in
       ``'ifAndOnlyIf'``.
     - ``Keyword("if")`` will not; it will only match the leading
       ``'if'`` in ``'if x=1'``, or ``'if(y==2)'``

    Accepts two optional constructor arguments in addition to the
    keyword string:

     - ``identChars`` is a string of characters that would be valid
       identifier characters, defaulting to all alphanumerics + "_" and
       "$"
     - ``caseless`` allows case-insensitive matching, default is ``False``.

    Example::

        Keyword("start").parseString("start")  # -> ['start']
        Keyword("start").parseString("starting")  # -> Exception

    For case-insensitive matching, use :class:`CaselessKeyword`.

raA variation on :class:`Literal` which matches "close" matches,
    that is, strings with at most 'n' mismatching characters.
    :class:`CloseMatch` takes parameters:

     - ``match_string`` - string to be matched
     - ``maxMismatches`` - (``default=1``) maximum number of
       mismatches allowed to count as a match

    The results from a successful parse will contain the matched text
    from the input string and the following named results:

     - ``mismatches`` - a list of the positions within the
       match_string where mismatches were found
     - ``original`` - the original match_string used to compare
       against the input string

    If ``mismatches`` is an empty list, then the match was an exact
    match.

    Example::

        patt = CloseMatch("ATCATCGAATGGA")
        patt.parseString("ATCATCGAAXGGA") # -> (['ATCATCGAAXGGA'], {'mismatches': [[9]], 'original': ['ATCATCGAATGGA']})
        patt.parseString("ATCAXCGAAXGGA") # -> Exception: Expected 'ATCATCGAATGGA' (with up to 1 mismatches) (at char 0), (line:1, col:1)

        # exact match
        patt.parseString("ATCATCGAATGGA") # -> (['ATCATCGAATGGA'], {'mismatches': [[]], 'original': ['ATCATCGAATGGA']})

        # close match allowing up to 2 mismatches
        patt = CloseMatch("ATCATCGAATGGA", maxMismatches=2)
        patt.parseString("ATCAXCGAAXGGA") # -> (['ATCAXCGAAXGGA'], {'mismatches': [[4, 9]], 'original': ['ATCATCGAATGGA']})

ZfddZZS)rLaX	Token for matching words composed of allowed character sets.
    Defined with string containing all allowed initial characters, an
    optional string containing allowed body characters (if omitted,
    defaults to the initial character set), and an optional minimum,
    maximum, and/or exact length.  The default value for ``min`` is
    1 (a minimum value < 1 is not valid); the default values for
    ``max`` and ``exact`` are 0, meaning no maximum or exact
    length restriction. An optional ``excludeChars`` parameter can
    list characters that might be found in the input ``bodyChars``
    string; useful to define a word of all printables except for one or
    two characters, for instance.

    :class:`srange` is useful for defining custom character set strings
    for defining ``Word`` expressions, using range notation from
    regular expression character sets.

    A common mistake is to use :class:`Word` to match a specific literal
    string, as in ``Word("Address")``. Remember that :class:`Word`
    uses the string argument to define *sets* of matchable characters.
    This expression would match "Add", "AAA", "dAred", or any other word
    made up of the characters 'A', 'd', 'r', 'e', and 's'. To match an
    exact literal string, use :class:`Literal` or :class:`Keyword`.

    pyparsing includes helper strings for building Words:

     - :class:`alphas`
     - :class:`nums`
     - :class:`alphanums`
     - :class:`hexnums`
     - :class:`alphas8bit` (alphabetic characters in ASCII range 128-255
       - accented, tilded, umlauted, etc.)
     - :class:`punc8bit` (non-alphabetic characters in ASCII range
       128-255 - currency, symbols, superscripts, diacriticals, etc.)
     - :class:`printables` (any non-whitespace character)

    Example::

        # a word composed of digits
        integer = Word(nums) # equivalent to Word("0123456789") or Word(srange("0-9"))

        # a word with a leading capital, and zero or more lowercase
        capital_word = Word(alphas.upper(), alphas.lower())

        # hostnames are alphanumeric, with leading alpha, and '-'
        hostname = Word(alphas, alphanums + '-')

        # roman numeral (not a strict parser, accepts invalid mix of characters)
        roman = Word("IVXLCDM")

        # any string of non-whitespace characters, except for ','
        csv_value = Word(printables, excludeChars=",")

S)rDahToken for matching strings that match a given regular
    expression. Defined with string specifying the regular expression in
    a form recognized by the stdlib Python  `re module <https://docs.python.org/3/library/re.html>`_.
    If the given regex contains named groups (defined using ``(?P<name>...)``),
    these will be preserved as named parse results.

    If instead of the Python stdlib re module you wish to use a different RE module
    (such as the `regex` module), you can replace it by either building your
    Regex object with a compiled RE that was compiled using regex:

    Example::

        realnum = Regex(r"[+-]?\d+\.\d*")
        date = Regex(r'(?P<year>\d{4})-(?P<month>\d\d?)-(?P<day>\d\d?)')
        # ref: https://stackoverflow.com/questions/267399/how-do-you-match-only-valid-roman-numerals-with-a-regular-expression
        roman = Regex(r"M{0,4}(CM|CD|D?{0,3})(XC|XL|L?X{0,3})(IX|IV|V?I{0,3})")

        # use regex module instead of stdlib re module to construct a Regex using
        # a compiled regular expression
        import regex
        parser = pp.Regex(regex.compile(r'[0-9]'))

rBa&
    Token for matching strings that are delimited by quoting characters.

    Defined with the following parameters:

        - quoteChar - string of one or more characters defining the
          quote delimiting string
        - escChar - character to escape quotes, typically backslash
          (default= ``None``)
        - escQuote - special quote sequence to escape an embedded quote
          string (such as SQL's ``""`` to escape an embedded ``"``)
          (default= ``None``)
        - multiline - boolean indicating whether quotes can span
          multiple lines (default= ``False``)
        - unquoteResults - boolean indicating whether the matched text
          should be unquoted (default= ``True``)
        - endQuoteChar - string of one or more characters defining the
          end of the quote delimited string (default= ``None``  => same as
          quoteChar)
        - convertWhitespaceEscapes - convert escaped whitespace
          (``'\t'``, ``'\n'``, etc.) to actual whitespace
          (default= ``True``)

    Example::

        qs = QuotedString('"')
        print(qs.searchString('lsjdf "This is the quote" sldjf'))
        complex_qs = QuotedString('{{', endQuoteChar='}}')

        sql_qs = QuotedString('"', escQuote='""')
        print(sql_qs.searchString('lsjdf "This is the quote with ""embedded"" quotes" sldjf'))

cs*eZdZdZfddZdddZZS)r*abLookahead matching of the given parse expression.
    ``FollowedBy`` does *not* advance the parsing position within
    the input string, it only verifies that the specified parse
    expression matches at the current position.  ``FollowedBy``
    always returns a null token list. If any results names are defined
    in the lookahead expression, those *will* be returned for access by
    name.

    Example::

        # use FollowedBy to match a label only if it is followed by a ':'
        data_word = Word(alphas)
        label = data_word + FollowedBy(':')
        attr_expr = Group(label + Suppress(':') + OneOrMore(data_word, stopOn=label).setParseAction(' '.join))

        OneOrMore(attr_expr).parseString("shape: SQUARE color: BLACK posn: upper left").pprint()

    prints::

ddZZS)r2apLookbehind matching of the given parse expression.
    ``PrecededBy`` does not advance the parsing position within the
    input string, it only verifies that the specified parse expression
    matches prior to the current position.  ``PrecededBy`` always
    returns a null token list, but if a results name is defined on the
    given expression, it is returned.

    Parameters:

     - expr - expression that must match prior to the current parse
       location
     - retreat - (default= ``None``) - (int) maximum number of characters
       to lookbehind prior to the current parse location

    If the lookbehind expression is a string, Literal, Keyword, or
    a Word or CharsNotIn with a specified exact or maximum length, then
    the retreat parameter is not required. Otherwise, retreat must be
    specified to give a maximum number of characters to look back from
    the current parse position for a lookbehind match.

    Example::

        # VB-style variable names with type prefixes
        int_var = PrecededBy("#") + pyparsing_common.identifier
        str_var = PrecededBy("$") + pyparsing_common.identifier

r5a¹Lookahead to disallow matching with the given parse expression.
    ``NotAny`` does *not* advance the parsing position within the
    input string, it only verifies that the specified parse expression
    does *not* match at the current position.  Also, ``NotAny`` does
    *not* skip over leading whitespace. ``NotAny`` always returns
    a null token list.  May be constructed using the '~' operator.

    Example::

        AND, OR, NOT = map(CaselessKeyword, "AND OR NOT".split())

        # take care not to mistake keywords for identifiers
        ident = ~(AND | OR | NOT) + Word(alphas)
        boolean_term = Optional(NOT) + ident

        # very crude boolean expression - to support parenthesis groups and
        # operation hierarchy, use infixNotation
        boolean_expr = boolean_term + ZeroOrMore((AND | OR) + boolean_term)

        # integers that are followed by "." are actually floats
        integer = Word(nums) + ~Char(".")

    expression is found.

    Parameters:
     - expr - target expression marking the end of the data to be skipped
     - include - (default= ``False``) if True, the target expression is also parsed
          (the skipped text and target expression are returned as a 2-element list).
     - ignore - (default= ``None``) used to define grammars (typically quoted strings and
          comments) that might contain false matches to the target expression
     - failOn - (default= ``None``) define expressions that are not allowed to be
          included in the skipped test; if found before the target expression is found,
          the SkipTo is not a match

    Example::

S)r+a_Forward declaration of an expression to be defined later -
    used for recursive grammars, such as algebraic infix notation.
    When the expression is known, it is assigned to the ``Forward``
    variable using the '<<' operator.

    Note: take care when assigning to ``Forward`` not to overlook
    precedence of operators.

    Specifically, '|' has a lower precedence than '<<', so that::

        fwdExpr << a | b | c

    will actually be evaluated as::

        (fwdExpr << a) | b | c

    thereby leaving b and c out as parseable alternatives.  It is recommended that you
    explicitly group the values inserted into the ``Forward``::

        fwdExpr << (a | b | c)

    Converting to use the '<<=' operator instead will avoid this problem.

    See :class:`ParseResults.pprint` for an example of a recursive
    parser created using ``Forward``.

r4YnX|S)aqDecorator for debugging parse actions.

    When the parse action is called, this decorator will print
    ``">> entering method-name(line:<current_source_line>, <parse_location>, <matched_tokens>)"``.
    When the parse action completes, the decorator will print
    ``"<<"`` followed by the returned value, or any exception that the parse action raised.

    Example::

        wd = Word(alphas)

        @traceParseAction
        def remove_duplicate_chars(tokens):
            return ''.join(sorted(set(''.join(tokens))))

        wds = OneOrMore(wd).setParseAction(remove_duplicate_chars)
        print(wds.parseString("slkdjs sld sldd sdlf sdljf"))

    prints::

¡S)a>Helper to define a counted list of expressions.

    This helper defines a pattern of the form::

        integer expr expr expr...

    where the leading integer tells how many expr expressions follow.
    The matched tokens returns the array of expr tokens as a list - the
    leading count token is suppressed.

    If ``intExpr`` is specified, it should be a pyparsing expression
    that produces an integer value.

    Example::

        countedArray(Word(alphas)).parseString('2 ab cd ef')  # -> ['ab', 'cd']

        # in this parser, the leading integer value is given in binary,
        # '10' indicating that 2 values are in the array

    Parameters:

       string literals
     - caseless - (default= ``False``) - treat all literals as
       caseless

((cCsttt||S)aéHelper to easily and clearly define a dictionary by specifying
    the respective patterns for the key and value.  Takes care of
    defining the :class:`Dict`, :class:`ZeroOrMore`, and
    :class:`Group` tokens in the proper order.  The key pattern
    can include delimiting markers or punctuation, as long as they are
    suppressed, thereby leaving the significant key text.  The value
    pattern can include named results, so that the :class:`Dict` results
    can include named token fields.

    Example::

        text = "shape: SQUARE posn: upper left color: light blue texture: burlap"
        attr_expr = (label + Suppress(':') + OneOrMore(data_word, stopOn=label).setParseAction(' '.join))
        print(OneOrMore(attr_expr).parseString(text).dump())

        attr_label = label
        attr_value = Suppress(':') + OneOrMore(data_word, stopOn=label).setParseAction(' '.join)

        # similar to Dict, but simpler call format
        result = dictOf(attr_label, attr_value).parseString(text)
        print(result.dump())
        print(result['shape'])
        print(result.shape)  # object attribute access works too
        print(result.asDict())

    prints::

    expression.  Useful to restore the parsed fields of an HTML start
    tag into the raw tag text itself, or to revert separate tokens with
    intervening whitespace back to the original matching input text. By
    default, returns astring containing the original parsed text.

    If the optional ``asString`` argument is passed as
    ``False``, then the return value is
    a :class:`ParseResults` containing any results names that
    were originally matched, and a single token containing the original
    matched text from the input string.  So if the expression passed to
    :class:`originalTextFor` contains expressions with defined
    results names, you must set ``asString`` to ``False`` if you
    want to preserve those results name values.

    Example::

        src = "this is test <b> bold <i>text</i> </b> normal text "
        for tag in ("b", "i"):
            opener, closer = makeHTMLTags(tag)

    T)r})rurrrrjëscs8|r|ddn| ¡ddDfdd}|S)a7Helper to create a validating parse action to be used with start
    tags created with :class:`makeXMLTags` or
    :class:`makeHTMLTags`. Use ``withAttribute`` to qualify
    a starting tag with a required attribute value, to avoid false
    matches on common tags such as ``<TD>`` or ``<DIV>``.

    Call ``withAttribute`` with a series of attribute names and
    values. Specify the list of filter attributes names and values as:

     - keyword arguments, as in ``(align="right")``, or
     - as an explicit dict with ``**`` operator, when an attribute
       name is also a Python reserved word, as in ``**{"class":"Customer", "align":"right"}``
     - a list of name-value tuples, as in ``(("ns1:class", "Customer"), ("ns2:align", "right"))``

    For attribute names with a namespace prefix, you must use the second
    form.  Attribute names are matched insensitive to upper/lower case.

    If just testing for ``class`` (with or without a namespace), use
    :class:`withClass`.

    To verify that the attribute exists, but without specifying a value,
    pass ``withAttribute.ANY_VALUE`` as the value.

Helper method for constructing grammars of expressions made up of
    operators working in a precedence hierarchy.  Operators may be unary
    or binary, left- or right-associative.  Parse actions can also be
    attached to operator expressions. The generated parser will also
    recognize the use of parentheses to override operator precedences
    (see example below).

    Note: if you define a deep operator list, you may see performance
    issues when using infixNotation. See
    :class:`ParserElement.enablePackrat` for a mechanism to potentially
    improve your parser performance.

    Parameters:
     - baseExpr - expression representing the most basic element for the
       nested
     - opList - list of tuples, one for each operator precedence level
       in the expression grammar; each tuple is of the form ``(opExpr,
       numTerms, rightLeftAssoc, parseAction)``, where:

       - opExpr is the pyparsing expression for the operator; may also
         be a string, which will be converted to a Literal; if numTerms
         is 3, opExpr is a tuple of two expressions, for the two
         operators separating the 3 terms
       - numTerms is the number of terms for this operator (must be 1,
         2, or 3)
       - rightLeftAssoc is the indicator whether the operator is right
         or left associative, using the pyparsing-defined constants
         ``opAssoc.RIGHT`` and ``opAssoc.LEFT``.
       - parseAction is the parse action to be associated with
         expressions matching this operator expression (the parse action
         tuple member may be omitted); if the parse action is passed
         a tuple or list of functions, this is equivalent to calling
         ``setParseAction(*fn)``
         (:class:`ParserElement.setParseAction`)
     - lpar - expression for matching left-parentheses
       (default= ``Suppress('(')``)
     - rpar - expression for matching right-parentheses
       (default= ``Suppress(')')``)

    Example::

        # simple example of four-function arithmetic with ints and
        # variable names
        integer = pyparsing_common.signed_integer
        varname = pyparsing_common.identifier

        arith_expr = infixNotation(integer | varname,
            [
            ('-', 1, opAssoc.RIGHT),
            (oneOf('* /'), 2, opAssoc.LEFT),
            (oneOf('+ -'), 2, opAssoc.LEFT),
            ])

        arith_expr.runTests('''
            5+3*6
            (5+3)*6
            -2--11
            ''', fullDump=False)

    prints::

        5+3*6
        [[5, '+', [3, '*', 6]]]

        (5+3)*6
        [[[5, '+', 3], '*', 6]]

    closing delimiters ("(" and ")" are the default).

    Parameters:
     - opener - opening character for a nested list
       (default= ``"("``); can also be a pyparsing expression
     - closer - closing character for a nested list
       (default= ``")"``); can also be a pyparsing expression
     - content - expression for items within the nested lists
       (default= ``None``)
     - ignoreExpr - expression for ignoring opening and closing
       delimiters (default= :class:`quotedString`)

    If an expression is not provided for the content argument, the
    nested expression will capture all whitespace-delimited content
    between delimiters as a list of separate values.

    Use the ``ignoreExpr`` argument to define expressions that may
    contain opening or closing characters that should not be treated as
    opening or closing characters for nesting, such as quotedString or
    a comment expression.  Specify multiple expressions using an
    :class:`Or` or :class:`MatchFirst`. The default is
    :class:`quotedString`, but if no expressions are to be ignored, then
    pass ``None`` for this argument.

    Example::

        data_type = oneOf("void int short long char float double")
        decl_data_type = Combine(data_type + Optional(Word('*')))
        ident = Word(alphas+'_', alphanums+'_')
        number = pyparsing_common.number
        arg = Group(decl_data_type + ident)
        LPAR, RPAR = map(Suppress, "()")

        code_body = nestedExpr('{', '}', ignoreExpr=(quotedString | cStyleComment))

        c_function = (decl_data_type("type")
                      + ident("name")
                      + LPAR + Optional(delimitedList(arg), [])("args") + RPAR
                      + code_body("body"))
        c_function.ignore(cStyleComment)

        source_code = '''
            int is_odd(int x) {
                return (x%2);
            }

                } else {
                    return (10+ord(hchar)-ord('A'));
                }

 d¡S)aæHelper method for defining space-delimited indentation blocks,
    such as those used to define block statements in Python source code.

    Parameters:

     - blockStatementExpr - expression defining syntax of statement that
       is repeated within the indented block
     - indentStack - list created by caller to manage indentation stack
       (multiple statementWithIndentedBlock expressions within a single
       grammar should share a common indentStack)
     - indent - boolean indicating whether block must be indented beyond
       the current level; set to False for block of left-most
       statements (default= ``True``)

    A valid block must contain at least one ``blockStatement``.

    Example::

        data = '''
        def A(z):
          A1
          B = 100
          G = A2

    A set of Unicode characters, for language-specific strings for
    ``alphas``, ``nums``, ``alphanums``, and ``printables``.
    A unicode_set is defined by a list of ranges in the Unicode character
    set, in a class attribute ``_ranges``, such as::

        _ranges = [(0x0020, 0x007e), (0x00a0, 0x00ff),]

    A unicode set can also be defined using multiple inheritance of other unicode sets::

z&pyparsing_test.reset_pyparsing_contextax
        Context manager to be used when writing unit tests that modify pyparsing config values:
         - packrat parsing
         - default whitespace characters.
         - default keyword characters
         - literal string auto-conversion class
         - __diag__ settings

        Example:
            with reset_pyparsing_context():
                # test that literals used to construct a grammar are automatically suppressed
                ParserElement.inlineLiteralsUsing(Suppress)

                term = Word(alphas) | Word(nums)
                group = Group('(' + term[...] + ')')

                # assert that the '()' characters are not included in the parsed tokens
                self.assertParseAndCheckLisst(group, "(abc 123 def)", ['abc', '123', 'def'])
