There are multiple conversations going on for weeks, and I think they are going nowhere. We could discuss for months what's the best plan for Groovy, without releasing anything. Here are the challenges that are waiting for us:
1. release a version of Groovy that integrates Groovy macros
2. upgrade the minimal runtime required for Groovy to 1.7, which is required to smoothly transition to higher requirements (and also, make our devs lives easier)
3. upgrade the minimal runtime required for Groovy to 1.8, allowing us to drop the old call site caching and use indy Groovy everywhere
4. integrate Parrot, which replaces the use of Antlr2 with Antlr4
5. compatibility with Jigsaw, aka "Groovy as a module"
I would like to propose the following plan:
- Groovy 2.5: integrates 1 and 2, to be released ASAP, we've been waiting for this for too long
- Groovy 2.6: integrate 4, implying backporting Parrot to Java 7
- Groovy 3.0: integrate 3 and 5. The only version with necessary breaking changes (we have no choice here)
This plan is, I think, a good compromise for all the requirements we have: backwards compatibility, and making progress and not having too many branches. An alternative would be to keep Parrot on Java 8, but as some of us have said, this is incompatible with a soonish release. The drawback is that Parrot has the risk of being a breaking change (it is, typically if people implicitly depend on the old parser, which would be bad), so there's a risk of not following semantic versioning.
- [ ] YES, I approve the roadmap above
- [ ] NO, I do not approve the roadmap abobe beause...
- [ ] I don't mind, or this goes beyond what I can think of
