Please let me know if you need anything else from me. > 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 > Assignee: Uwe Schindler > Attachments: LUCENE-6471.patch, LUCENE-6471.patch > > > 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
