__init__(self, expr, savelist=False)
x.__init__(...) initializes x; see help(type(x)) for signature

source code

parseImpl(self, instring, loc, doActions=True)

source code

leaveWhitespace(self)
Disables the skipping of whitespace before matching the characters in the :class:`ParserElement`'s defined pattern.

source code

ignore(self, other)
Define expression to be ignored (e.g., comments) while doing pattern matching; may be called repeatedly, to define multiple comment or other ignorable patterns.

checkRecursion(self, parseElementList)

source code

validate(self, validateTrace=None)

Method Details

[hide private]

init(self, expr, savelist=False)
(Constructor)

source code

x.__init__(...) initializes x; see help(type(x)) for signature

Overrides: object.__init__: (inherited documentation)

parseImpl(self, instring, loc, doActions=True)

source code

Overrides: ParserElement.parseImpl

leaveWhitespace(self)

source code

Disables the skipping of whitespace before matching the characters in the :class:`ParserElement`'s defined pattern. This is normally only used internally by the pyparsing module, but may be needed in some whitespace-sensitive grammars.

Overrides: ParserElement.leaveWhitespace: (inherited documentation)

ignore(self, other)

source code

Define expression to be ignored (e.g., comments) while doing pattern matching; may be called repeatedly, to define multiple comment or other ignorable patterns.

Example:

   patt = OneOrMore(Word(alphas))
   patt.parseString('ablaj /* comment */ lskjd') # -> ['ablaj']

   patt.ignore(cStyleComment)
   patt.parseString('ablaj /* comment */ lskjd') # -> ['ablaj', 'lskjd']

Overrides: ParserElement.ignore: (inherited documentation)

Check defined expressions for valid structure, check for infinite recursive definitions.

Overrides: ParserElement.validate: (inherited documentation)

str(self)
(Informal representation operator)

source code

str(x)

Overrides: object.__str__: (inherited documentation)
