(Mostly notable for my purposes because it includes golang as a code generation target.)

Nice to see C++ and Go in 4.6 mainline. I've been stuck on ANTLR 3 in order to use C++ and it's great to see the new target finally mainlined. Go is good and I'd like to see a Rust target sometime soon.

Nice to see Swift added to the list of targets. Any idea about the performance of generated parsers in Swift vs other targets?

I'd be interested see pointers to ANTLR-based languages people are developing. I found it to be a powerful tool, but also limiting.

As far as I know, ANTLR v4 is even more of a "framework" than v3, in that it dictates your program structure and always outputs a full parse tree. It appears to have lost the ability to verify the value of k for LL(k) grammars, due to a more powerful underlying algorithm.

I think that simplifies it for most use cases but makes others hard or impossible.

Just curious if anyone has used ANTLR on Android lately; I recall it was easy to run out of stack because the runtime relies on very deep recursion.

Also I think there were some dependencies on AWT or Swing for debug console.

Same here. Antlr is great, finally the wait for reintroduction of C++ support is over. Never nice to see features removed in newer releases of software you want to use.

Agreed! I hope full (not half-hearted and late) C++ support becomes the 'new normal' for ANTLR.

Compiler design was one subject that I struggled with when I was an undergrad. I feel this has held me back from creating DSLs. I am looking for a gentle introduction to ANTLR that can take me from newbie to mastery. Any books anyone can recommend would be helpful.
