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:: 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+rUrrs r-set_results_namezParserElement.set_results_names%<(;+;##D.999r/c||S|}|dr |dd}d}||_| |_|S)NrrT)r endswithrr)r+rUrnewselfs r-rzParserElement._setResultsName1sW <K))++ ==   "9D!N"#11r/T break_flagc|r|jdfd }|_||_n&t|jdr|jj|_|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 ```` 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 ''') Nc34K|]}t|VdSr))callablerCrs r- z1ParserElement.set_parse_action..s(22x||222222r/zparse actions must be callablec,g|]}t|Sr9rr)s r-rEz2ParserElement.set_parse_action..s>>>B B>>>r/call_during_tryrF)rrallrgetrr+r%kwargss r-set_parse_actionzParserElement.set_parse_actionSsV 99  !D  22c22222 B @AAA>>#>>>D !'!6::ou#E#E""D  r/c|xjd|Dz c_|jp)|d|dd|_|S)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.

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.

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. rTrNcg|]}||Sr9r9rCos r-rEz2ParserElement.transform_string..s'''Q'1'''r/r~c,g|]}t|Sr9r)rCrs r-rEz2ParserElement.transform_string..s:::qCFF:::r/)rrr rSr rrr#extendjoinrrmrrr) r+rroutlastErrr=rs r-transform_stringzParserElement.transform_stringso(  /++HE+BB  1a 8E!G,---&!!\22&qyy{{*#Ax00&Ax9P9P& 1  1  JJx' ( ( (''c'''C77::HSMM:::;; ;! / / // /((...  /sDD## E-"EEct||} td||||DS#t$r'}tjr|dd}~wwxYw)a Another extension to :class:`scan_string`, simplifying the access to the tokens found to match the given parse expression.

If you want to test a string that spans multiple lines, create a test like this:: expr.run_tests(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'``.) r)pyparsing_testc&g|] }|Sr9r9)rC test_line line_strips r-rEz+ParserElement.run_tests..s#XXXyZZ **XXXr/NT\n uFr~r=)fullz{} failed: {}: {}z(FATAL)zFAIL: zFAIL-EXCEPTION: {}: {})&testingrRrSr#rstriprstrip splitlinesLiteralsysstdoutwriter5 replace_withr  quoted_stringrr rPrrlstriprr dumprrRrr2rmrexplainrrrr format_tbr)r+rIrrJrKrLrMrNrOrPrrFrGrHrLrRprint_ allResultscommentssuccessNLBOMrrrupp_valuer=rsrrrUs @r- run_testszParserElement.run_testss` ,+++++) ) #5 #4} + eX & & Ye*JXXXXELLNNtyy****B7HO00333aCH& ;'' 66**1*AA "6,&6(#,9Q#7#7#/)(LAA: # 8==?? ; ; ; ; # 3x== 9 9 9 9JJv{{}}555$ 6;;H;#=#=>>> /66 ) 2DGG4DaJJv{{{99::::E&   %/4G%H%HP b 2::<<((( 8c"gg-... 3FJJy223CDDEEE!2l    3::499;MsSSTTT 3GJJy233DEEFFF!2l  6 JJrNNN 'tyy~~&&&   q&k * * * * ""s@?LBI'' K&1A*K!!K& QB#O QA9QQr$ output_htmlverticalshow_results_names show_groupsc  ddlm}m}n"#t$r}t d|d}~wwxYw|||||||} t |ttfrKt|dd5} | || ddddS#1swxYwYdS| || dS) a Create a railroad diagram for the parser.

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']}) NrF) maxMismatchesrrmax_mismatchesrc||n|}t||_||_d|j|j|_||_d|_d|_dS)Nz(Expected {!r} (with up to {} mismatches)F) rr.rrrrrrr)r+rrrrrs r-r.zCloseMatch.__init__ sz+9*D-  (*@GG  t1   !

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 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, exclude_chars=",") r~NrrF) initChars bodyChars asKeyword excludeChars init_chars body_charsrmaxexact as_keyword exclude_charsrrr r c~|p|}| p|} | p|} | p|} t|s4tdt |jt |}||_| r(t | } || z}| rt | | z } dt||_ | rEEJJ'   NN "  :|,,L  %I : NN\9 WWVI%6%677  ,!# ):):!;!;D  ^^DNN!# ):):!;!;D  ^^DN!G 77g  77DKK"DK 199DKDK!DI- "" dnt~5 5 53!88QR ~//!88 FFAXXFF(// 4;(+B+BRR F!).t~>>!!

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``.
