ANTLR

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

Stackoverflow.com is our question and answer mechanism:

http://stackoverflow.com/questions/tagged/antlr

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:

https://groups.google.com/forum/#!forum/antlr-discussion

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

Channel is called #antlr and lives at irc.oftc.net. (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.

Upon receipt of the paypal payment, you will be taken to a page with the special email address. For more information or to get a price quote on something else, contact Terence directly: parrt at antlr dot org.
