Kyungho Jeon commented on PIG-2597: ----------------------------------- This is my initial draft: https://github.com/kyunghoj/GSoC2014 I am not sure how much details should be in design section. Also, I realized that other components based on JavaCC (e.g., Parameter substitution) might be bigger beasts. Should those component be included in this project? > Move grunt from javacc to ANTRL > ------------------------------- > > 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.
