With the recent port to Antlr 4.11.1, we discovered a couple of the grammars required some tweaking. But, as noted [here](https://github.com/antlr/antlr4/issues/3875#issuecomment-1242668939), we can simplify the asm8080 grammar further. **We should...
While using the grammars-v4/bnf grammar for creating an ebnf, I noticed several errors: * [LPAREN](https://github.com/antlr/grammars-v4/blob/07314e4615982ba77864d7b8cd804c7b5d803bb0/bnf/bnf.g4#L91), [RPARENT](https://github.com/antlr/grammars-v4/blob/07314e4615982ba77864d7b8cd804c7b5d803bb0/bnf/bnf.g4#L95) and the other symmetrical character symbols are reversed on [how it is usually defined](https://wumbo.net/symbols/right-parenthesis/)....

## Statement of Problem This is a fix for https://github.com/antlr/grammars-v4/issues/2883 Testing in the V4 repo should be incremental, meaning that if one grammar changes, the build will only test the...
Antlr 4.12.0 will be released soon. The builds in grammars-v4 should be updated once the release is available. * Add the TypeScript target. * Make Antlr4 version setting from one...
Perhaps this is better in the Discussions section, but I just don't understand why we aren't performing tree diffs on every parse, across all targets. It's not going to slow...
The [php]() grammar crashes when trying to print out trees (`trgen -t Java; cd Generated-Java; make; make test`). ``` Exception in thread "main" java.lang.NullPointerException at org.antlr.v4.runtime.misc.Utils.escapeWhitespace(Utils.java:63) at org.antlr.v4.runtime.tree.Trees.toStringTree(Trees.java:49) at org.antlr.v4.runtime.tree.Trees.toStringTree(Trees.java:58)...

While updating every template for testing (https://github.com/antlr/grammars-v4/pull/2989), I noticed that the Python3 target does not work on the logo/logo grammar, crashing on a file open: ``` ../examples/logo_feature_butfail_2.txt Traceback (most recent...
