ModelCC r2015

(October 2015)

Here you can find a proof-of-concept implementation of ModelCC for Java. The provided implementation employs an optimized Earley-like chart parser, a dynamic programming algorithm for parsing context-free grammars that runs in cubic time for arbitrary context-free grammars, in quadratic time for unambiguous context-free grammars, and in linear time for most LR(k) grammars.

ModelCC release notes

  • Comprehensive JUnit test suite, including all the examples in the ModelCC tutorial (see test.modelcc.language.*).
    • Improved lexer API for unlimited data streams (org.modelcc.lexer.Tokenizer), available both for FLEX and LAMB lexers.
    • Line number and offset information for debugging input streams (org.modelcc.lexer.Token)
  • Language grammar decoupled from Java object instantiation.
    • Generic Model & JavaModelReader, with LanguageModel & JavaLanguageReader subclasses for context-free languages.
    • Improved message logging facilities (org.modelcc.io.MessageLogger).
    • Support for separate compilation by means of predefined model elements, e.g.
    • Parser<Expression> parser = createParser();
    • parser.add(new Constant("pi", 3.1415927));
    • assertEquals(3.1415927, parser.parse("pi").eval(), EPSILON);
    • assertEquals(2*3.1415927, parser.parse("2*pi").eval(), EPSILON);
