Class White

source code


Special matching class for matching whitespace. Normally, whitespace is ignored by pyparsing grammars. This class is included when some whitespace structures are significant. Define with a string containing the whitespace characters to be matched; default is " \t\n". Also takes optional min, max, and exact arguments, as defined for the Word class.
