This repository contains Jython translations of some of the ANTLR4 examples found in the book "The Definitive ANTLR4 Reference" by Terrance Parr. The original, java examples can be downloaded from: http://pragprog.com/titles/tpantlr2/source_code

The following steps assume:

• jython is in your system's execution path - Jython 2.7b1 was used.
• The ANTLR v4 library (jar file) is in the CLASSPATH.
• a4 command invokes the ANTLR v4 Tool.
