PEG Library
This page describes the Parsing Expression Library implementation for Eiffel. Information about PEGs can be found here [1].
Basic classes
All the parsers inherit from PEG_ABSTRACT_PEG which defines the common functionalities. The parsers are the same as in the definition of Wikipedia with the additional classes like whitespace support.
The parsers are combined to a object hierarchy which defines the grammar. A string can then be parsed via the the feature parser.parse_string ("Some source") on the root object.
