Known Subclasses:

Abstract subclass of ParserElement, for combining and post-processing parsed tokens.

Instance Methods

__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 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.

source code

streamline(self)

source code

checkRecursion(self, parseElementList)

source code

validate(self, validateTrace=[])
Check defined expressions for valid structure, check for infinite recursive definitions. source code

Method Details

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 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)
