ANTLR

Features

ANTLR is a parser generator.

• Generates Java, C#, or C++ code.

• Accepts the class of LL(k) grammars

• Produces recursive-descent parsers

• Includes mini grammar base, as well as several example applications of ANTLR

• Tree grammars which let you use grammar constructs to specify how to walk your AST. It also has a notation for building and transforming your AST.

Applications

A complete skeleton of an ANTLR based transformation system for ANSI C and C with GCC extesions can be seen at http://www.codetransform.com/gcc.html. Included are a parser, tree parser (to be "grammar subclassed" for your transformation passes), and a tree emitter to take your tree back to text.

History

Formerly part of PCCTS. See also SORCERER.
