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)

### streamline(self) | source code
Overrides: ParserElement.streamline

### checkRecursion(self, parseElementList) | source code
Overrides: ParserElement.checkRecursion

### validate(self, validateTrace=`[``]`) | source code
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)
