Version 3 of ANTLR (ANother Tool for Language Recognition) created and written by Dr. Terrence Parr

Version 3 of ANTLR.

What is ANTLR?

"ANTLR, ANother Tool for Language Recognition, is a language tool that provides a framework for constructing recognizers, interpreters, compilers, and translators from grammatical descriptions containing actions in a variety of target languages. ANTLR provides excellent support for tree construction, tree walking, translation, error recovery, and error reporting. ..." -- http://www.antlr.org

Updated links

On January 24th 2013, the www.antlr.org address was changed from pointing at site for ANTLR version 3 (www.antlr3.org) to ANTLR version 4 (www.antlr4.org). So questions and answers that used www.antlr.org were correct for ANTLR 3.x before this date. The links should be updated to www.antlr3.org for ANTLR 3.x or www.antlr4.org for ATNLR 4.x.
