Daniel Dai commented on PIG-2597: --------------------------------- I glance through Boski Shah's patch, one thing we need to avoid is to introduce another Driver (GruntDriver), we shall merge all parsing logic into QueryParser. > Move grunt from javacc to ANTLR > ------------------------------- > > Key: PIG-2597 > URL: https://issues.apache.org/jira/browse/PIG-2597 > Project: Pig > Issue Type: Improvement > Reporter: Jonathan Coveney > Assignee: Daniel Dai > Labels: gsoc2014 > Attachments: pig02.diff > > > Currently, the parser for queries is in ANTLR, but Grunt is still javacc. The > parser is very difficult to work with, and next to impossible to understand > or modify. ANTLR provides a much cleaner, more standard way to generate > parsers/lexers/ASTs/etc, and moving from javacc to Grunt would be huge as we > continue to add features to Pig. > This is a candidate project for Google summer of code 2014.
