ModelCC r2014 (July 2014)

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 beta4 release notes (July 2014)

  • Fully-refactored OO implementation of ModelCC and its associated JUnit test suite.

  • 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);
