Jack Conradson created LUCENE-6417: -------------------------------------- Summary: Upgrade ANTLR to version 4.5 Key: LUCENE-6417 URL: https://issues.apache.org/jira/browse/LUCENE-6417 Project: Lucene - Core Issue Type: Improvement Reporter: Jack Conradson
I would like to upgrade ANTLR from 3.5 to 4.5. This version adds several features that will improve the existing grammars. The main improvement would be the allowance of left-hand recursion in grammar rules which will reduce the number of rules significantly for expressions. This change will require some code refactoring to the existing expressions work. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
