Abstract subclass of ParserElement, for combining and post-processing parsed tokens.
Method Summary
  __init__(self, expr, savelist)
  __str__(self)
  checkRecursion(self, parseElementList)
  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.
  leaveWhitespace(self)
Disables the skipping of whitespace before matching the characters in the ParserElement's defined pattern.
  parseImpl(self, instring, loc, doActions)
  streamline(self)
  validate(self, validateTrace)
Check defined expressions for valid structure, check for infinite recursive definitions.

Instance Method Details

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.
Overrides:
pyparsing.ParserElement.ignore (inherited documentation)

leaveWhitespace(self)

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:
pyparsing.ParserElement.leaveWhitespace (inherited documentation)

validate(self, validateTrace=[])

Check defined expressions for valid structure, check for infinite recursive definitions.
Overrides:
pyparsing.ParserElement.validate (inherited documentation)
