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 ``", !"``), built up using :class:`Word`, :class:`Literal`, and :class:`And` elements (the :class:`'+'` operators create :class:`And` expressions, and the strings are auto-converted to :class:`Literal` expressions):: from pip._vendor.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:`'+'`, :class:`'|'`, :class:`'^'`, and :class:`'&'` 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` namespace class z2.4.7z30 Mar 2020 00:43 UTCz*Paul McGuire N)ref)datetime) itemgetter)wraps)contextmanager) filterfalse) ifilterfalse)RLock)Iterable)MutableMappingMapping) OrderedDict)SimpleNamespaceceZdZdS)rN)__name__ __module__ __qualname__/builddir/build/BUILDROOT/alt-python311-pip-21.3.1-3.el8.x86_64/opt/alt/python311/lib/python3.11/site-packages/pip/_vendor/pyparsing.pyrrsrraA A cross-version compatibility configuration for pyparsing features that will be released in a future version.

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. rN r^z{0}: {1})contextr) parseImpl _parseNoCachez {0}.{1} - {2}z{0}.{1})wrapperzz{0} )inspectrgetrecursionlimitrrCappendrnr`formatrrgetinnerframes __traceback__set enumeratef_localsgetrJf_codeco_nameaddrr) excdepthrrcallersseenifffrmf_self self_typecodes rexplainzParseException.explainsN0  =)++E c- . . 2 JJsx JJscgk*S0 1 1 1 :$$T#YY%7==>>> 199,,S->,NNG55D"7E677#344  2e))&$77fm44;z)1OOO ~~ HHV$$$ $V IJJ55i6J6?6H6< > >????' $V IJJy// 0D090B D DEEEE:D|'>>> JJu||DL99::: Eyy~~rN)r)rrrr staticmethodr%rrrrErEksD,BBB\BBBrrEceZdZdZdS)rGznuser-throwable exception thrown when inconsistent parse content is found; stops all parsing immediatelyNrrrrrrrrGrGs22DrrGceZdZdZdS)rIzjust 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.

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.

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.

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=",") NrrFcJtt|rStdfd|D}|r!dfd|D}||_t||_|r||_t||_n||_t||_|dk|_ |dkrtd||_ |dkr||_ n t|_ |dkr||_ ||_ t||_d|jz|_d|_||_d |j|jzvr2|dkr-|dkr(|dkr#|j|jkrd t'|jz|_nt+|jdkr7t-j|jd t'|jd |_n2d t'|jd t'|jd |_|jrd|jzdz|_ t-j|j|_|jj|_t6|_dS#t:$r d|_YdSwxYwdSdSdSdS)Nrc3$K|] }|v|V dSrrrr excludeCharss rrz Word.__init__..H s-NNa8M8M8M8M8M8MNNrc3$K|] }|v|V dSrrrs rrz Word.__init__..J s-#R#R!A\r ) rrrminmaxexactrrr>s `rrz Word.__init__D s dD""$$$  S|,,LNNNN9NNNNNI SGG#R#R#R#Ry#R#R#RRR &Y  ,!*D  ^^DNN!*D  ^^DN!G 77yzz z 77DKK"DK 199DKDK$KK !DI- "" d(4+== = =3!88PSWXPXPX]bfg]g]g!T%777 '*@AS*T*T T T'((A---/Yt7I-J-J-J-J-CDDV-W-W-W-W!Z .0FdFX/Y/Y/Y/Y/EdFX/Y/Y/Y/Y!\ ~ > % 5 =  ,*T]33!%  !+      > =88PXPX]g]gsJJJTc|||jvrt|||j||}|dz }t|}|j}||jz}t ||}||kr|||vr|dz }||kr |||vd}||z |jkrd}nF|jr||kr |||vrd}n,|j r%|dkr ||dz |vs||kr |||vrd}|rt|||j|||||fS)NrFTr) rrErarrrrrrr) rrrrzrr bodycharsrthrowExceptions rr zWord.parseImpl} sY C= . . 3 TBB B qx==N $VX&&Fllx} 99 1HCFllx} 99 ; $ $!NN   &3>>hsmy6P6P!NN ^ & huqy1Y>>X~~(3-9*D*D!%  C 3 TBB BHU3Y'''rc< tt|S#t$rYnwxYw|jVd}|j|jkr+d||jd||jd|_nd||jz|_|jS)NcFt|dkr |dddzS|S)Nrr)rs r charsAsStrz Word.__str__..charsAsStr s(q66A::RaR55=(HrzW:(rrzW:(%s))rrUrr rUrr)rrr>s rrz Word.__str__ s t$$,,.. .

Defined with string specifying the regular expression in a form recognized by the stdlib Python `re module `_. If the given regex contains named groups (defined using ``(?P...)``), 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\d{4})-(?P\d\d?)-(?P\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]')) rFc^tt|t|tr|st jdtd||_||_ tj |j|j |_ |j|_ n#tj$r!t jd|ztdwxYwt|dr2t|dr"||_ |jx|_|_ ||_ nt!d|j j|_t'||_d|jz|_d |_|d d u|_||_||_|jr |j|_|jr|j|_d Sd S) aThe parameters ``pattern`` and ``flags`` are passed to the ``re.compile()`` function as-is.

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.

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 bold text normal text " for tag in ("b", "i"): opener, closer = makeHTMLTags(tag) patt = originalTextFor(opener + SkipTo(closer) + closer) print(patt.searchString(src)[0]) prints:: [' bold text '] ['text'] c|Srr)rrrs rrz!originalTextFor..srF_original_start _original_endc*||j|jSr)rrrs rrz!originalTextFor..sa(91?(J&Krcr||d|dg|dd<dS)Nrr)rrs r extractTextz$originalTextFor..extractTexts9aee-..quu_/E/EEFGAaaaDDDr)r2rrrdr])rasString locMarker endlocMarker matchExprrs rrrs:&&'<'<==I>>##L %L +,,t3ll?6S6SSIHKK  H H H [))) ,I rcHt|dS)zkHelper to undo pyparsing's default grouping of And expressions, even if all but one are non-empty. c|dSr<rrs rrzungroup..s 1r)rSr)rs rrrs" $   . .~~ > >>rctd}t|d|dz|dzS)aHelper to decorate a returned token with its starting and ending locations in the input string.

Use ``withAttribute`` to qualify a starting tag with a required attribute value, to avoid false matches on common tags such as ```` or ``
``. 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. Example:: html = '''

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.
