ANTLR Community Support

ANTLR is supported by Terence Parr, Sam Harwell, and target language folks (see top of the code generation targets documentation) as well as the multitude of helpful users of ANTLR. 

ANTLR Questions is our question and answer mechanism:

ANTLR Discussions

Please do not start discussions at stackoverflow. They have asked us to steer discussions (i.e., non-questions/answers) away from Stackoverflow; we have a discussion forum at Google specifically for that:!forum/antlr-discussion

We can discuss ANTLR project features, direction, and generally argue about whatever we want at the google discussion forum.


The archives from the previous mailing list dealing with v3 may still be of use to you:

Channel is called #antlr and lives at (Terence does not listen to this channel)

Commercial ANTLR (and StringTemplate) Technical Support

Terence Parr, the primary author of ANTLR/StringTemplate and all around nice guy, is available to ensure your project is successful. You can purchase technical support for $3,000 per year. For the duration, you can ask Terence direct questions about ANTLR and StringTemplate. Contact is email-only and replies are sent within one business day, often within hours. This support consists of answering questions and providing advice, not building grammars or other software. Note: Terence is only able to answer questions related to the Java target. If you are a commercial enterprise or otherwise have money to throw around, you should consider purchasing tech support. The following button takes you to paypal:
Check this customer report (JBoss Rules folks) to learn more about the kind of consulting and/or tech support you can expect.
