Normally, results names are assigned as you would assign keys in a dict: any existing value is overwritten by later values. If it is necessary to keep all values captured for a particular results name, call ``set_results_name`` with ``list_all_matches`` = True. NOTE: ``set_results_name`` returns a *copy* of the original :class:`ParserElement` object; this is so that the client can define a basic element, such as an integer, and reference it in multiple places with different names. You can also set results names using the abbreviated syntax, ``expr("name")`` in place of ``expr.set_results_name("name")`` - see :class:`__call__`. If ``list_all_matches`` is required, use ``expr("name*")``. Example:: integer = Word(nums) date_str = (integer.set_results_name("year") + '/' + integer.set_results_name("month") + '/' + integer.set_results_name("day")) # equivalent form: date_str = integer("year") + '/' + integer("month") + '/' + integer("day") )_setResultsName)r. rT r r s r0 set_results_namez ParserElement.set_results_name' s" > (;+;##D.99r2 c | || S | j }|j d r|d d }d}||_ | |_ |S )Nr" r T)r endswithr r )r. rT r newselfs r0 r z ParserElement._setResultsNameI sK <K))+ == 9D !N "#1 1 r2 T break_flagc |r"| j dfd }|_ || _ | S t | j d r| j j | _ | S )z Method to invoke the Python pdb debugger when this element is about to be parsed.

Parse actions can be called to perform data conversions, do extra validation, update external data structures, or enhance or replace the parsed tokens. Each 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 The parsed tokens are passed to the parse action as ParseResults. They can be modified in place using list-style append, extend, and pop operations to update the parsed list elements; and with dictionary-style item set and del operations to add, update, or remove any named results. If the tokens are modified in place, it is not necessary to return them with a return statement. Parse actions can also completely replace the given tokens, with another ``ParseResults`` object, or with some entirely different object (common for parse actions that perform data conversions). A convenient way to build a new parse result is to define the values using a dict, and then create the return value using :class:`ParseResults.from_dict`. If None is passed as the ``fn`` parse action, all previously added parse actions for this expression are cleared. Optional keyword arguments: - ``call_during_try`` = (default= ``False``) indicate if parse action should be run during lookaheads and alternate testing. For parse actions that have side effects, it is important to only call the parse action once it is determined that it is being called as part of a successful parse. For parse actions that perform additional validation, then call_during_try should be passed as True, so that the validation code is included in the preliminary "try" parses. Note: the default parsing behavior is to expand tabs in the input string before starting the parsing process. See :class:`parse_string` 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:: # parse dates in the form YYYY/MM/DD # use parse action to convert toks from str to int at parse time def convert_to_int(toks): return int(toks[0]) # use a parse action to verify that the date is a valid date def is_valid_date(instring, loc, toks): from datetime import date year, month, day = toks[::2] try: date(year, month, day) except ValueError: raise ParseException(instring, loc, "invalid date given") integer = Word(nums) date_str = integer + '/' + integer + '/' + integer # add parse actions integer.set_parse_action(convert_to_int) date_str.set_parse_action(is_valid_date) # note that integer fields are now ints, not strings date_str.run_tests(''' # successful parse - note that integer fields were converted to ints 1999/12/31 # fail - invalid date 1999/13/31 ''') Nc 3 2 K | ] }t | y wr, )callable)rI r s r0 r z1ParserElement.set_parse_action.<locals>.<genexpr> s .#B8B<# z parse actions must be callablecall_during_tryr F)r r allr r getr r. r* kwargsr s r0 set_parse_actionz ParserElement.set_parse_actionj s V 9 !D K.#.. <= =69:cKOc: #ZZ vzz/5 A ;s A=c | xj |D cg c] }t | c}z c_ | j xs" |j d|j dd | _ | S c c}w )z Add one or more parse actions to expression's list of parse actions.

During parsing, left-recursive :class:`Forward` elements are repeatedly matched with a fixed recursion depth that is gradually increased until finding the longest match. Example:: import pyparsing as pp pp.ParserElement.enable_left_recursion() E = pp.Forward("E") num = pp.Word(pp.nums) # match `num`, or `num '+' num`, or `num '+' num '+' num`, ... E <<= E + '+' - num | num print(E.parse_string("1+2+3")) Recursion search naturally memoizes matches of ``Forward`` elements and may thus skip reevaluation of parse actions during backtracking. This may break programs with parse actions which rely on strict ordering of side-effects. Parameters: - ``cache_size_limit`` - (default=``None``) - memoize at most this many ``Forward`` elements during matching; if ``None`` (the default), memoize all ``Forward`` elements. Bounded Recursion parsing works similar but not identical to Packrat parsing, thus the two cannot be used together. Use ``force=True`` to disable any previous, conflicting settings. 0Packrat and Bounded Recursion are not compatibleNr )capacityz Memo size of T) r r r RuntimeError_UnboundedMemoro _LRUMemoNotImplementedErrorr r r s r0 enable_left_recursionz#ParserElement.enable_left_recursion s| H - - / * * QR R #,:,<M ) 15 - !,4>N,OM ) 15 - & 6F5G&HI Ir2 r c & |rt j nt j r t d t j rydt _ | t t _ nt | t _ t j t _ y)aj 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.enable_packrat`. For best results, call ``enable_packrat()`` immediately after importing pyparsing. Example:: import pyparsing pyparsing.ParserElement.enable_packrat() Packrat parsing works similar but not identical to Bounded Recursion parsing, thus the two cannot be used together.

This function is intended as the primary interface to the client code. :param instring: The input string to be parsed. :param parse_all: If set, the entire input string must match the grammar. :param parseAll: retained for pre-PEP8 compatibility, will be removed in a future release. :raises ParseException: Raised if ``parse_all`` is set and the input string does not match the whole grammar. :returns: the parsed data as a :class:`ParseResults` object, which may be accessed as a `list`, a `dict`, or an object with attributes if the given parser includes results names. If the input string is required to match the entire grammar, ``parse_all`` flag must be set to ``True``. This is also equivalent to ending the grammar with :class:`StringEnd`\ (). To report proper column numbers, ``parse_string`` operates on a copy of the input string where all tabs are converted to spaces (8 spaces per tab, as per the default in ``string.expandtabs``). If the input string contains tabs and the grammar uses parse actions that use the ``loc`` argument to index into the string being parsed, one can ensure a consistent view of the input string by doing one of the following: - calling ``parse_with_tabs`` on your grammar before calling ``parse_string`` (see :class:`parse_with_tabs`), - define your parse action using the full ``(s,loc,toks)`` signature, and reference the input string using the parse action's ``s`` argument, or - explicitly expand the tabs in your input string before calling ``parse_string``. Examples: By default, partial matches are OK. >>> res = Word('a').parse_string('aaaaabaaa') >>> print(res) ['aaaaa'] The parsing behavior varies by the inheriting class of this abstract class. Please refer to the children directly to see more examples. It raises an exception if parse_all flag is set and instring does not match the whole grammar. >>> res = Word('a').parse_string('aaaaabaaa', parse_all=True) Traceback (most recent call last): ... pyparsing.ParseException: Expected end of text, found 'b' (at char 5), (line:1, col:6) r N)r r r streamliner r expandtabsr' rJ Empty StringEndr| r with_traceback) r. r r r r? r ra ser s r0 parse_stringzParserElement.parse_stringo s Z (!!# OO !!A LLN "}} **,H ++h2KCmmHc2Wy{* (C( M " / // ((.. /s 5AC C7"C22C7)r maxMatches max_matchesoverlapr r c # K t || }| j s| j | j D ] }|j | j st | j }t | }d}| j } | j } t j d} ||k r}| |k rw | || } | || d \ } }| |kD rG| dz } |r t |j | | d || | f |r | || }||kD r| }n|dz }n | }n| dz } ||k r| |k ruyyyy# t $ r dz }Y w xY w# t $ r'}t j r |j# d d}~ww xY ww)at Scan the input string for expression matches.

To use ``transform_string``, define a grammar and attach a parse action to it that modifies the returned token list. Invoking ``transform_string()`` on a target string will then scan for matches, and replace the matched text patterns according to the logic in the parse action. ``transform_string()`` returns the resulting transformed string. Example:: wd = Word(alphas) wd.set_parse_action(lambda toks: toks[0].title()) print(wd.transform_string("now is the winter of our discontent made glorious summer by this sun of york.")) prints:: Now Is The Winter Of Our Discontent Made Glorious Summer By This Sun Of York. r Tr Nrw )r r r rY r# r r r& r joinr r8 r| r r r ) r. r r outlastEr r r? or s r0 transform_stringz ParserElement.transform_string s& ( + ++HE+B1a 8E!,- a .199;&C 8,Z85LJJqMJJqM C JJx' ( !'cQ1cC'77HSM:MqCFM:; ; (:! + // $$T* * +s< B4D D D D 'D9D D D:"D55D:c t || } t | j ||| D cg c] \ }}}| c}}} S c c}}}w # t $ r'}t j r |j d d}~ww xY w)a Another extension to :class:`scan_string`, simplifying the access to the tokens found to match the given parse expression.

Set ``flag`` to ``True`` to enable, ``False`` to disable. Set ``recurse`` to ``True`` to set the debug flag on this expression and all sub-expressions. Example:: wd = Word(alphas).set_name("alphaword") integer = Word(nums).set_name("numword") term = wd | integer # turn on debugging for wd wd.set_debug() term[1, ...].parse_string("abc 123 xyz 890") prints:: Match alphaword at loc 0(1,1) Matched alphaword -> ['abc'] Match alphaword at loc 3(1,4) Exception raised:Expected alphaword (at char 4), (line:1, col:5) Match alphaword at loc 7(1,8) Matched alphaword -> ['xyz'] Match alphaword at loc 11(1,12) Exception raised:Expected alphaword (at char 12), (line:1, col:13) Match alphaword at loc 15(1,16) Exception raised:Expected alphaword (at char 15), (line:1, col:16) The output shown is that produced by the default debug actions - custom debug actions can be specified using :class:`set_debug_actions`. 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:`set_name` 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 ``set_name`` is ``"W:(A-Za-z)"``.

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 - ``parse_all`` - (default= ``True``) - flag to pass to :class:`parse_string` when running tests - ``comment`` - (default= ``'#'``) - expression for indicating embedded comments in the test string; pass None to disable comment filtering - ``full_dump`` - (default= ``True``) - dump results as list followed by results names in nested outline; if False, only dump nested list - ``print_results`` - (default= ``True``) prints test output to stdout - ``failure_tests`` - (default= ``False``) indicates if these tests are expected to fail parsing - ``post_parse`` - (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`` - ``with_line_numbers`` - default= ``False``) show test strings with line and column numbers Returns: a (success, results) tuple, where success indicates that all tests succeeded (or failed if ``failure_tests`` 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.run_tests(''' # 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.run_tests(''' # stray character 100Z # missing leading digit before '.' -.100 # too many '.' 3.14.159 ''', failure_tests=True) print("Success" if result[0] else "Failed!") prints:: # unsigned integer 100 [100] # negative integer -100 [-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.

Example:: patt = CloseMatch("ATCATCGAATGGA") patt.parse_string("ATCATCGAAXGGA") # -> (['ATCATCGAAXGGA'], {'mismatches': [[9]], 'original': ['ATCATCGAATGGA']}) patt.parse_string("ATCAXCGAAXGGA") # -> Exception: Expected 'ATCATCGAATGGA' (with up to 1 mismatches) (at char 0), (line:1, col:1) # exact match patt.parse_string("ATCATCGAATGGA") # -> (['ATCATCGAATGGA'], {'mismatches': [[]], 'original': ['ATCATCGAATGGA']}) # close match allowing up to 2 mismatches patt = CloseMatch("ATCATCGAATGGA", max_mismatches=2) patt.parse_string("ATCAXCGAAXGGA") # -> (['ATCAXCGAAXGGA'], {'mismatches': [[4, 9]], 'original': ['ATCATCGAATGGA']}) r F) maxMismatchesr r max_mismatchesr c ||n|}t | || _ || _ d| j d| j d| _ || _ d| _ d| _ y )Nr( z (with up to z mismatches)F)r r1 r r r r r r )r. r r r r r s r0 r1 zCloseMatch.__init__Y sh +9*D- ( *!$"3"3!6mDDVDVCWWcd " #r2 rW c J t | j d| j S )Nrt )r r5 r r s r0 r$ z CloseMatch._generateDefaultNamej s% t*%%&a(9(9'<==r2 c |}t | }|t | j z }||k r| j }d}g } | j } t t ||| | D ]] \ }} | \ } } | j r | j | j } } | | k7 s=| j | t | | kD s] n& ||z dz }t ||| g }||d< | |d< ||fS t ||| j | )Nr r original mismatches) rG r r enumeratezipr ry r r# r r )r. r r r! r rH maxlocr match_stringlocr r s_msrcmatresultss r0 rM zCloseMatch.parseImplm s x=T . .// X ,,L OJ . .M(1HS(,7)$ S== "yy{CIIKC#: %%o6: 6 ) o-1&s(;'<=&2 #(2 %G|# XsDKK>>r2 r, r ) r5 r: r; rA r8 r r r} r1 r$ rM r r s @r0 r r 6 sV J 04$ $$ ,$ $">c > ?r2 r c e Zd ZdZ dddddddedej e deded ed ed ej e d ej e d ej e dedej e f fdZ defdZ ddZ ddZ xZ S )Worda> Token for matching words composed of allowed character sets. Parameters: - ``init_chars`` - string of all characters that should be used to match as a word; "ABC" will match "AAA", "ABAB", "CBAC", etc.; if ``body_chars`` is also specified, then this is the string of initial characters - ``body_chars`` - string of characters that can be used for matching after a matched initial character as given in ``init_chars``; if omitted, same as the initial characters (default=``None``) - ``min`` - minimum number of characters to match (default=1) - ``max`` - maximum number of characters to match (default=0) - ``exact`` - exact number of characters to match (default=0) - ``as_keyword`` - match as a keyword (default=``False``) - ``exclude_chars`` - characters that might be found in the input ``body_chars`` string but which should not be accepted for matching ;useful to define a word of all printables except for one or two characters, for instance (default=``None``) :class:`srange` is useful for defining custom character set strings for defining :class:`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) ``alphas``, ``nums``, and ``printables`` are also defined in several Unicode sets - see :class:`pyparsing_unicode``. 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 capitalized_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, exclude_chars=",") NF) initChars bodyChars asKeyword excludeChars init_chars body_charsr maxexact as_keyword exclude_charsr r! r" r# c |xs |}| xs |} | xs |} | xs |} t | |s"t dt | j d t | } | r/t | } | | z } | r dj t | | z } | | _ dj t | | _ | r0t | | _ dj t | | _ n| | _ | j | _ |dkD | _ |dk r t d | j r||kD rt d| d| d || _ |dkD r|| _ n t | _ |dkD r|x}}|| _ || _ d | j | _ d | _ | | _ | j& r| xj" d z c_ d | j | j z vrt) | j dk( r t+ j, | j }ndt/ | j d}| j | j k( r|dk( r| j dk( rd}nd|dk( rd}n\| j | j k7 r3d| j d| j t k( rdn | j d}nd| j d}| | | _ n|dk( rd}d}nrdt/ | j d}|dk( r| j dk( rd}nB|dk( r |dk rdnd}n3||k7 r d|dkD r|dz nd d|dkD r|dz nd d}nd|dkD r|dz nd d}| | | | _ | j& rd| j0 d| _ t+ j2 | j0 | _ | j* j4 | _ | j8 | _ y y # t* j< $ r d | _ Y y w xY w)Nzinvalid z", initChars cannot be empty stringrw r r zUcannot specify a minimum length < 1; use Opt(Word()) if zero-length word is permittedzDinvalid args, if min and max both specified min must be <= max (min=z, max=r r( Fz as a keywordr [r +{r }r" rd ?z\b) r r1 r r r5 r r r sorted initCharsOrigr! bodyCharsOrig maxSpecifiedminLenmaxLenr rT r r r" rG reescaper reStringcompiler re_matchparseImpl_regexrM error)r. r$ r% r r& r' r( r) r r! r" r# initChars_setexcludeChars_setre_leading_fragmentrepeatre_body_fragmentr s r0 r1 z Word.__init__ s + + + #4} 4:..//QR I "< 0 - -M GGC N5E$E F & WWVM%: ; ^DN!# ):!;D *DN!%!3!3D !G 7 g s VWZV[[abeaffgh 7 DK"DK 19 C# DK DK!$))- "" >> KK? *K t~~6 74>>"a'&(ii0B0B&C#()*DT^^*T)UUV&W#~~ /!8 q 0 FAX F{{dkk1#%dkk]!$++:QBW[WbWb3cce!f#%dkk]"!5#6"7x @ !8')$ F)*+Ednn+U*VVW'X$axDKK1$4!$ (+qb #:')S1W#'")EQRUXYRYsQw_aFbbd%eF')S1W#'")ER%HF#6"78H7I& R ~~#%dmm_B 7 6 **T]]3 !% !%!5!5Y 8P 88 s &$N8 8OOrW c d }| j | j k7 r*d || j d || j d}nd || j d}| j dkD s| j t k7 r| j | j k( r'| j dk( r|dd S |d| j dz S | j t k( r|d| j d z S |d| j d | j dz S |S ) Nc V d}t | d } t | |kD r | d |dz dz S | S )N F) re_escaper' r )r rG )r max_repr_lens r0 charsAsStrz-Word._generateDefaultName.<locals>.charsAsStrG s< L*1>A1v $+<!+,u44Hr2 zW:(, r r rd r- r. z,...}r )r r! r4 r5 r )r. rG bases r0 r$ zWord._generateDefaultNameF s >>T^^ +DNN34Bz$..7Q6RRSTDDNN34A6D ;;?dkkX 5{{dkk);;!# 8O Bt{{m2"666(4;;-v 6664;;-q R @@@ r2 c || | j vrt ||| j | |}|dz }t | }| j }|| j z }t || }||k r|| |v r|dz }||k r|| |v rd}||z | j k rd}nD| j r||k r || |v rd}n)| j r |dkD r ||dz |v s ||k r || |v rd}|rt ||| j | |||| fS )Nr FTr ) r r r rG r! r5 r r4 r3 r" ) r. r r r! r rH bodycharsr throwExceptions r0 rM zWord.parseImplb s* C= . 3 TB B qx=NN $VX&Flx} 9 1HC Flx} 9 ; $ !N 3>hsmy6P !N ^^ QY8EAI.);h8C=I#= !N 3 TB BHU3'''r2 c | j || }|st ||| j | |j }||j fS r, )r: r r r group)r. r r r! r s r0 r; zWord.parseImpl_regex sF x- 3 TB BjjlFLLN""r2 )rw Nr r r FNr )r5 r: r; rA r8 r r r} rx r1 r$ rM r; r r s @r0 r r s @H +/ .2t6 +/*. -1t6t6 OOC(t6 t6 t6 t6 t6 s+t6 ??3't6 ??3't6 t6 ooc*t6lc 8(:#r2 r c z e Zd ZdZ d ddddededej e ded ej e f fd Z xZ S ) CharzA short-cut class for defining :class:`Word` ``(characters, exact=1)``, when defining a match of any single character in a string of characters.

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 :class:`ParseResults`. If instead of the Python stdlib ``re`` module you wish to use a different RE module (such as the ``regex`` module), you can do so by building your ``Regex`` object with a compiled RE that was compiled using ``regex``. Example:: realnum = Regex(r"[+-]?\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})") # named fields in a regex will be returned as named results date = Regex(r'(?P<year>\d{4})-(?P<month>\d\d?)-(?P<day>\d\d?)') # the Regex class will accept re's compiled using the regex module import regex parser = pp.Regex(regex.compile(r'[0-9]')) F) asGroupListasMatchpatternflags as_group_listas_matchrU rV c t | |xs |}|xs |}t |t r*|s t d d| _ |x| _ | _ || _ nJt |d r3t |d r'|| _ |j x| _ | _ || _ n t d d| j | _ d| _ || _ || _ | j r| j | _ | j r| j$ | _ yy)a The parameters ``pattern`` and ``flags`` are passed to the ``re.compile()`` function as-is.

By default, the list elements and delimiters can have intervening whitespace, and comments, but this can be overridden by passing ``combine=True`` in the constructor.

If ``allow_trailing_delim`` is set to True, then the list may end with a delimiter.

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:: fwd_expr << a | b | c will actually be evaluated as:: (fwd_expr << 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``:: fwd_expr << (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``. r c r t j d d | _ t | |d d | _ y )Nrd r r Fr )r r caller_framer r1 lshift_liner s r0 r1 zForward.__init__ s5 % 3 3! <Q ? / r2 rW c t | d r| `t |t r| j | }t |t st S || _ |j | _ | j j | _ | j j | _ | j | j j | j j | j j | _ | j j | _ | j j# | j j t% j& d d | _ | S )Nr< r rd r )r( r< rY r& r r r r r r r r r r r r r r r r r= r s r0 __lshift__zForward.__lshift__ s 4 (! eX &,,U3E% /! ! ,, !YY 4 4 "ii 6 6 !!
