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 C{"<salutation>, <addressee>!"}), built up using L{Word}, L{Literal}, and L{And} elements (L{'+'<ParserElement.__add__>} operator gives L{And} expressions, strings are auto-converted to L{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 L{ParseResults} object returned from L{ParserElement.parseString<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 L{ParserElement} and L{ParseResults} to see the base classes that most other pyparsing classes inherit from.

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 C{"<salutation>, <addressee>!"}), built up using L{Word}, L{Literal}, and L{And} elements (L{'+'<ParserElement.__add__>} operator gives L{And} expressions, strings are auto-converted to L{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 L{ParseResults} object returned from L{ParserElement.parseString<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 L{ParserElement} and L{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 L{Literal} and L{CaselessLiteral} classes - construct character word-group expressions using the L{Word} class - see how to create repetitive expressions using L{ZeroOrMore} and L{OneOrMore} classes - use L{'+'<And>}, L{'\|'<MatchFirst>}, L{'^'<Or>}, and L{'&'<Each>} operators to combine simple expressions into more complex ones - associate names with your parsed results using L{ParserElement.setResultsName} - find some helpful expression short-cuts like L{delimitedList} and L{oneOf} - find more useful common expressions in the L{pyparsing_common} namespace class s��2.2.1s��18 Sep 2018 00:49 UTCs��Paul McGuire <ptmcg@users.sourceforge.net>i��N(��t��ref(��t��datetime(��t��RLock(��t��Iterable(��t��MutableMapping(��t��OrderedDictt��Andt��CaselessKeywordt��CaselessLiteralt ��CharsNotInt��Combinet��Dictt��Eacht��Emptyt ��FollowedByt��Forwardt ��GoToColumnt��Groupt��Keywordt��LineEndt ��LineStartt��Literalt ��MatchFirstt��NoMatcht��NotAnyt ��OneOrMoret��OnlyOncet��Optionalt��Ort��ParseBaseExceptiont��ParseElementEnhancet��ParseExceptiont��ParseExpressiont��ParseFatalExceptiont��ParseResultst��ParseSyntaxExceptiont ��ParserElementt��QuotedStringt��RecursiveGrammarExceptiont��Regext��SkipTot ��StringEndt��StringStartt��Suppresst��Tokent��TokenConvertert��Whitet��Wordt��WordEndt ��WordStartt ��ZeroOrMoret ��alphanumst��alphast ��alphas8bitt��anyCloseTagt ��anyOpenTagt ��cStyleCommentt��colt��commaSeparatedListt��commonHTMLEntityt��countedArrayt��cppStyleCommentt��dblQuotedStringt��dblSlashCommentt ��delimitedListt��dictOft��downcaseTokenst��emptyt��hexnumst��htmlCommentt��javaStyleCommentt��linet��lineEndt ��lineStartt��linenot��makeHTMLTagst��makeXMLTagst��matchOnlyAtColt��matchPreviousExprt��matchPreviousLiteralt ��nestedExprt��nullDebugActiont��numst��oneOft��opAssoct��operatorPrecedencet ��printablest��punc8bitt��pythonStyleCommentt��quotedStringt��removeQuotest��replaceHTMLEntityt��replaceWitht ��restOfLinet��sglQuotedStringt��sranget ��stringEndt��stringStartt��traceParseActiont ��unicodeStringt��upcaseTokenst ��withAttributet ��indentedBlockt��originalTextFort��ungroupt ��infixNotationt��locatedExprt ��withClasst ��CloseMatcht��tokenMapt��pyparsing_commoni��i��c��C��s}��t��\|��t��r�\|��Sy�t�\|��SWnU�t�k �rx�t�\|��j�t�j��d��}�t�d��}�\|�j�d��\|�j �\|��SXd�S(��s��Drop-in replacement for str(obj) that tries to be Unicode friendly.

Parse action fn is a callable method with 0-3 arguments, called as C{fn(s,loc,toks)}, C{fn(loc,toks)}, C{fn(toks)}, or just C{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 C{L{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.

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=C{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 C{ParserElement.enablePackrat()}. If your program uses C{psyco} to "compile as you go", you must call C{enablePackrat} before calling C{psyco.full()}. If you do not do this, Python will crash. For best results, call C{enablePackrat()} immediately after importing pyparsing. Example:: import pyparsing pyparsing.ParserElement.enablePackrat() N( ��R$��t��_packratEnabledR��R��R��R��R��R��R��(��t��cache_size_limit(��(��sP��/opt/alt/python27/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyt ��enablePackrat%��s�� c��C��s��t��j��\|��j�s �\|��j��n��x�\|��j�D]�}�\|�j��q�W\|��j�sV�\|�j��}�n��yW�\|��j�\|�d��\�}�}�\|�r��\|��j�\|�\|��}�t ��t ��}�\|�j�\|�\|��n��Wn(�t�k �r��}�t��j�r��q��\|��n�X\|�Sd�S(��sB�� Execute the parse expression with the given string. This is the main interface to the client code, once the complete expression has been built. If you want the grammar to require that the entire input string be successfully parsed, then set C{parseAll} to True (equivalent to ending the grammar with C{L{StringEnd()}}). Note: C{parseString} implicitly calls C{expandtabs()} on the input string, in order to report proper column numbers in parse actions. If the input string contains tabs and the grammar uses parse actions that use the C{loc} argument to index into the string being parsed, you can ensure you have a consistent view of the input string by: - calling C{parseWithTabs} on your grammar before calling C{parseString} (see L{I{parseWithTabs}<parseWithTabs>}) - define your parse action using the full C{(s,loc,toks)} signature, and reference the input string using the parse action's C{s} argument - explictly expand the tabs in your input string before calling C{parseString} Example:: Word('a').parseString('aaaaabaaa') # -> ['aaaaa'] Word('a').parseString('aaaaabaaa', parseAll=True) # -> Exception: Expected end of text i��N( ��R$��R��Rx��t ��streamlineRv��Ru��t ��expandtabsR��R��R ��R)��R��t��verbose_stacktrace(��R��RG��t��parseAllR��R��R��t��seRN��(��(��sP��/opt/alt/python27/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyt��parseStringH��s$�� c��c��s��\|��j��s�\|��j��n��x�\|��j�D]�}�\|�j��q �W\|��j�sR�t�\|��j��}�n��t�\|��}�d�}�\|��j�}�\|��j�}�t �j ��d�} �y��x��\|�\|�k�ra\| �\|�k��ray.�\|�\|�\|��} �\|�\|�\| �d�t��\�}�}�Wn�t�k �r��\| �d�}�q��X\|�\|�k�rT\| �d�7} �\|�\| �\|�f�V\|�rK\|�\|�\|��} �\| �\|�k�r>\|�}�qQ\|�d�7}�q^\|�}�q��\| �d�}�q��WWn(�t �k �r�}�t �j�r��q�\|��n�Xd�S(��s�� Scan the input string for expression matches.

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=C{True}) - flag to pass to C{L{parseString}} when running tests - comment - (default=C{'#'}) - expression for indicating embedded comments in the test string; pass None to disable comment filtering - fullDump - (default=C{True}) - dump results as list followed by results names in nested outline; if False, only dump nested list - printResults - (default=C{True}) prints test output to stdout - failureTests - (default=C{False}) indicates if these tests are expected to fail parsing Returns: a (success, results) tuple, where success indicates that all tests succeeded (or failed if C{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 [-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.

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 C{min} is 1 (a minimum value < 1 is not valid); the default values for C{max} and C{exact} are 0, meaning no maximum or exact length restriction. An optional C{excludeChars} parameter can list characters that might be found in the input C{bodyChars} string; useful to define a word of all printables except for one or two characters, for instance. L{srange} is useful for defining custom character set strings for defining C{Word} expressions, using range notation from regular expression character sets. A common mistake is to use C{Word} to match a specific literal string, as in C{Word("Address")}. Remember that C{Word} uses the string argument to define I{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 L{Literal} or L{Keyword}. pyparsing includes helper strings for building Words: - L{alphas} - L{nums} - L{alphanums} - L{hexnums} - L{alphas8bit} (alphabetic characters in ASCII range 128-255 - accented, tilded, umlauted, etc.) - L{punc8bit} (non-alphabetic characters in ASCII range 128-255 - currency, symbols, superscripts, diacriticals, etc.) - L{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=",") i��i��c��s��t��t�\|��j��rc�d�j��f�d��\|�D��}�\|�rc�d�j��f�d��\|�D��}�qc�n��\|�\|��_�t�\|��\|��_�\|�r��\|�\|��_�t�\|��\|��_�n�\|�\|��_�t�\|��\|��_�\|�d�k�\|��_ �\|�d�k��r��t �d��n��\|�\|��_�\|�d�k�r��\|�\|��_�n �t �\|��_�\|�d�k�r)\|�\|��_�\|�\|��_�n��t�\|��\|��_�d�\|��j�\|��_�t�\|��_�\|�\|��_�d�\|��j�\|��j�k�r}\|�d�k�r}\|�d�k�r}\|�d�k�r}\|��j�\|��j�k�r�d �t�\|��j��\|��_�ne�t�\|��j��d�k�r�d �t�j�\|��j��t�\|��j��f�\|��_�n%�d�t�\|��j��t�\|��j��f�\|��_�\|��j�rDd�\|��j�d�\|��_�n��y�t�j�\|��j��\|��_�Wq}t�k �ryd��\|��_�q}Xn��d��S( ��NRt��c��3��s!��\|��]�}�\|��k�r�\|�Vq�d��S(��N(��(��R��R��(��t��excludeChars(��sP��/opt/alt/python27/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pys ��<genexpr>` ��s��c��3��s!��\|��]�}�\|��k�r�\|�Vq�d��S(��N(��(��R��R��(��R>��(��sP��/opt/alt/python27/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pys ��<genexpr>b ��s��i��i��sZ��cannot specify a minimum length < 1; use Optional(Word()) if zero-length word is permitteds ��Expected R��s��[%s]+s��%s[%s]s ��[%s][%s]s��\b(��R ��R/��R��R��t ��initCharsOrigR��t ��initCharst ��bodyCharsOrigt ��bodyCharst��maxSpecifiedR��t��minLent��maxLenR&��R��R��Rz��R��Ry��t ��asKeywordt��_escapeRegexRangeCharst��reStringR��R}��t��escapet��compileRb��R��(��R��R@��RB��t��mint��maxt��exactRF��R>��(��(��R>��sP��/opt/alt/python27/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyR��] ��sT��% : c�� C��s��\|��j��r[�\|��j��j�\|�\|��}�\|�s?�t�\|�\|�\|��j�\|��n��\|�j��}�\|�\|�j��f�S\|�\|�\|��j�k�r��t�\|�\|�\|��j�\|��n��\|�}�\|�d�7}�t�\|��}�\|��j�}�\|�\|��j �}�t �\|�\|��}�x�\|�\|�k��r��\|�\|�\|�k�r��\|�d�7}�q��Wt�} �\|�\|�\|��j�k��rt �} �n��\|��j�rG\|�\|�k��rG\|�\|�\|�k�rGt �} �n��\|��j�r�\|�d�k�rp\|�\|�d�\|�k�s�\|�\|�k��r�\|�\|�\|�k�r�t �} �q�n��\| �r�t�\|�\|�\|��j�\|��n��\|�\|�\|�\|�!f�S(��Ni��i��(��R}��R'��R��Rz��t��endt��groupR@��R��RB��RE��RK��R��RD��R��RC��RF��( ��R��RG��R��R��R#��R7��R��t ��bodycharsR8��t��throwException(��(��sP��/opt/alt/python27/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyR�� s6�� % <c��C��s��y�t��t�\|��j��SWn�t�k �r�n�X\|��j�d��k�r��d��}�\|��j�\|��j�k�r}�d�\|�\|��j��\|�\|��j��f�\|��_�q��d�\|�\|��j��\|��_�n��\|��j�S(��Nc��S��s&��t��\|��d�k�r�\|��d� d�S\|��Sd��S(��Ni��s��...(��R��(��R��(��(��sP��/opt/alt/python27/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyt ��charsAsStr� ��s��s ��W:(%s,%s)s��W:(%s)(��R ��R/��R��Rb��Rn��R��R?��RA��(��R��RR��(��(��sP��/opt/alt/python27/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyR�� s�� (N( ��R��R��R��R��R��R��R��R��R��(��(��(��sP��/opt/alt/python27/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyR/��. ��s��.6#c��B��sD��e��Z�d��Z�e�e�j�d��Z�d�d��Z�e�d��Z �d��Z �RS(��s�� Token for matching strings that match a given regular expression.

When the expression is known, it is assigned to the C{Forward} variable using the '<<' operator. Note: take care when assigning to C{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 C{Forward}:: fwdExpr << (a \| b \| c) Converting to use the '<<=' operator instead will avoid this problem.

Call C{withAttribute} with a series of attribute names and values. Specify the list of filter attributes names and values as: - keyword arguments, as in C{(align="right")}, or - as an explicit dict with C{} operator, when an attribute name is also a Python reserved word, as in C{{"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 C{class} (with or without a namespace), use C{L{withClass}}. To verify that the attribute exists, but without specifying a value, pass C{withAttribute.ANY_VALUE} as the value.

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 L{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 C{opAssoc.RIGHT} and C{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 C{setParseAction(fn)} (L{ParserElement.setParseAction}) - lpar - expression for matching left-parentheses (default=C{Suppress('(')}) - rpar - expression for matching right-parentheses (default=C{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+36 (5+3)6 -2--11 ''', fullDump=False) prints:: 5+36 [[5, '+', [3, '', 6]]] (5+3)6 [[[5, '+', 3], '', 6]] -2--11 [[['-', 2], '-', ['-', 11]]] i��i��s��%s terms ��%s%s termi��s@��if numterms=3, opExpr must be a tuple or list of two expressionsi��s6��operator must be unary (1), binary (2), or ternary (3)s2��operator must indicate right or left associativityN(��N(��R��R��R��R��R��R��RT��t��LEFTR��R��R��t��RIGHTRu��R��RH��R��R��R\|��(��t��baseExprt��opListt��lpart��rparR��t��lastExprR��t��operDeft��opExprt��arityt��rightLeftAssocR��t��termNamet��opExpr1t��opExpr2t��thisExprR��(��(��sP��/opt/alt/python27/lib/python2.7/site-packages/pkg_resources/_vendor/pyparsing.pyRi��sV��= '/' $/' s4��"(?:[^"\n\r\\]\|(?:"")\|(?:\\(?:[^x]\|x[0-9a-fA-F]+)))t��"s ��string enclosed in double quotess4��'(?:[^'\n\r\\]\|(?:'')\|(?:\\(?:[^x]\|x[0-9a-fA-F]+)))t��'s ��string enclosed in single quotess��quotedString using single or double quotest��us��unicode string literalc��C��s!��\|��\|�k�r�t��d��n��\|�d �k�r�t�\|��t��rt�\|�t��rt�\|��d�k�r��t�\|��d�k�r��\|�d �k �r��t�t�\|�t�\|��\|�t�j �d�d��j �d��}�q\|t�j��t�\|��\|�t�j ��j �d��}�q�\|�d �k �r9t�t�\|�t �\|��t �\|��t�t�j �d�d��j �d��}�q�t�t�t �\|��t �\|��t�t�j �d�d��j �d��}�q�t��d��n��t��}�\|�d �k �r�\|�t�t�\|��t�\|�\|�B\|�B��t�\|��K}�n.�\|�t�t�\|��t�\|�\|�B��t�\|��K}�\|�j�d �\|��\|�f��\|�S(��s~ �� Helper method for defining nested lists enclosed in opening and closing delimiters ("(" and ")" are the default).

Use the C{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 C{L{Or}} or C{L{MatchFirst}}. The default is L{quotedString}, but if no expressions are to be ignored, then pass C{None} for this argument.
