Hello, In the drools team, we are developing a new Antlr4 based DRL parser. The current parser is Antlr3 based and contains lots of hard-coded logic in a generated java code (DRL6Parser.java), so it's hard to maintain.
Originally the new parser was developed under https://github.com/kiegroup/drools-lsp/ at the early stage. Now we are testing the new DRL parser with the existing drool unit tests using a feature branch `dev-new-parser`. We hit lots of test failures (as expected) and are fixing them one-by-one. This is the parent issue where Jiri Locker made a great effort to split child issues (test failures): https://github.com/apache/incubator-kie-drools/issues/5678 Those child issues are fine grained, so it would be nice to contribute! If you are willing to contribute, please put you as an assignee (if you have a committer permission) or post a comment to avoid duplicate work on the child issue. Also you can track the progress by watching the parent issue and share your thoughts any time you want. Cheers, Toshiya
