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 
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

        Removes and returns item at specified index (default=C{last}).
        Supports both C{list} and C{dict} semantics for C{pop()}. If passed no

        and pop tokens from the list of parsed tokens. If passed a 
        non-integer argument (most likely a string), it will use C{dict}
        semantics and pop the corresponding value from any defined

        Define action to perform when successfully matching parse element definition.
        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.

        Optional keyword arguments:
         - callDuringTry = (default=C{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 L{I{parseString}<parseString>} for more information
        on parsing strings containing C{<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

i�cCsUtjsQtt_|dkr0tj�t_ntj|�t_tjt_ndS(s�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=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()

        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']

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

        Implementation of + operator - returns C{L{And}}. Adding strings to a ParserElement
        converts them to L{Literal}s by default.

            hello = "Hello, World!"

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

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

        The output shown is that produced by the default debug actions - custom debug actions can be
        specified using L{setDebugActions}. Prior to attempting
        to match the C{wd} expression, the debugging message C{"Match <exprname> at loc <n>(<line>,<col>)"}
        is shown. Then if the parse succeeds, a C{"Matched"} message is shown, or an C{"Exception raised"}
        message is shown. Also note the use of L{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 C{Word} expression without calling C{setName} is C{"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=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('''

        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'.)

    Token to exactly match a specified string as a keyword, that is, it must be
    immediately followed by a non-keyword character.  Compare with C{L{Literal}}:
     - C{Literal("if")} will match the leading C{'if'} in C{'ifAndOnlyIf'}.
     - C{Keyword("if")} will not; it will only match the leading C{'if'} in C{'if x=1'}, or C{'if(y==2)'}
    Accepts two optional constructor arguments in addition to the keyword string:
     - C{identChars} is a string of characters that would be valid identifier characters,
          defaulting to all alphanumerics + "_" and "$"
     - C{caseless} allows case-insensitive matching, default is C{False}.
       
    Example::
        Keyword("start").parseString("start")  # -> ['start']

    A variation on L{Literal} which matches "close" matches, that is, 
    strings with at most 'n' mismatching characters. C{CloseMatch} takes parameters:
     - C{match_string} - string to be matched
     - C{maxMismatches} - (C{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:
     - C{mismatches} - a list of the positions within the match_string where mismatches were found
     - C{original} - the original match_string used to compare against the input string
    
    If C{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)

    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 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=",")

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

    Example::
        qs = QuotedString('"')

    Token for skipping over all undefined text until the matched expression is found.

    Parameters:
     - expr - target expression marking the end of the data to be skipped
     - include - (default=C{False}) if True, the target expression is also parsed 
          (the skipped text and target expression are returned as a 2-element list).
     - ignore - (default=C{None}) used to define grammars (typically quoted strings and 
          comments) that might contain false matches to the target expression
     - failOn - (default=C{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

    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 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.

    See L{ParseResults.pprint} for an example of a recursive parser created using
    C{Forward}.

    Helper to define a delimited list of expressions - the delimiter defaults to ','.
    By default, the list elements and delimiters can have intervening whitespace, and
    comments, but this can be overridden by passing C{combine=True} in the constructor.
    If C{combine} is set to C{True}, the matching tokens are returned as a single token
    string, with the delimiters included; otherwise, the matching tokens are returned
    as a list of tokens, with the delimiters suppressed.

    Helper to quickly define a set of alternative Literals, and makes sure to do
    longest-first testing when there is a conflict, regardless of the input order,
    but returns a C{L{MatchFirst}} for best performance.

    Parameters:
     - strs - a string of space-delimited literals, or a collection of string literals
     - caseless - (default=C{False}) - treat all literals as caseless
     - useRegex - (default=C{True}) - as an optimization, will generate a Regex
          object; otherwise, will generate a C{MatchFirst} object (if C{caseless=True}, or

    Helper to easily and clearly define a dictionary by specifying the respective patterns
    for the key and value.  Takes care of defining the C{L{Dict}}, C{L{ZeroOrMore}}, and C{L{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 C{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))

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

        # similar to Dict, but simpler call format

    Helper to return the original, untokenized text for a given 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 C{asString} argument is passed as C{False}, then the return value is a 
    C{L{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 C{L{originalTextFor}} contains expressions with defined
    results names, you must set C{asString} to C{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)

    Helper to create a validating parse action to be used with start tags created
    with C{L{makeXMLTags}} or C{L{makeHTMLTags}}. Use C{withAttribute} to qualify a starting tag
    with a required attribute value, to avoid false matches on common tags such as
    C{<TD>} or C{<DIV>}.

    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.

    Example::
        html = '''

    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 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)
     - 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+3*6
            (5+3)*6
            -2--11
            ''', fullDump=False)
    prints::
        5+3*6

    Helper method for defining nested lists enclosed in opening and closing
    delimiters ("(" and ")" are the default).

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

    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

    Helper 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
            the current level; set to False for block of left-most statements
            (default=C{True})

    A valid block must contain at least one C{blockStatement}.

    Here are some common low-level expressions that may be useful in jump-starting parser development:
     - numeric forms (L{integers<integer>}, L{reals<real>}, L{scientific notation<sci_real>})
     - common L{programming identifiers<identifier>}
     - network addresses (L{MAC<mac_address>}, L{IPv4<ipv4_address>}, L{IPv6<ipv6_address>})
     - ISO8601 L{dates<iso8601_date>} and L{datetime<iso8601_datetime>}
     - L{UUID<uuid>}
     - L{comma-separated list<comma_separated_list>}
    Parse actions:
     - C{L{convertToInteger}}
     - C{L{convertToFloat}}
     - C{L{convertToDate}}
     - C{L{convertToDatetime}}
     - C{L{stripHTMLTags}}
     - C{L{upcaseTokens}}
     - C{L{downcaseTokens}}
