In order for the test scripts to identify the set of grammars changed, it's going to need to work in several ways. * Work with locally modified files that are...

Tested the "git diff" that [I mentioned before](https://github.com/antlr/grammars-v4/issues/2883#issuecomment-1373622751). ``` $ git diff 17776ce4de459b9118db60d0907e2ea6401c9363 799781e6d196512ea403c52fe41f38f357026f2c --name-only java/java/JavaParser.g4 java/java/examples/AllInOne17.java java/java/examples/RecordsTesting.java java/java/examples/RecordsTesting.java.tree ``` This "git diff" caused tester.ps1 to test not just the...

* Make sure you select the "Lexer" tab and clear out the contents. You did not, which is why you get the error message "". * Make sure you have...

Which grammar? Expr.g4 or JavaLexer.g4/JavaParser.g4? Those are the only two discussed. https://github.com/antlr/antlr4-tools#parsing-using-interpreter

The default example at lab.antlr.org is supposed to contain the error. It's a demo of how it reports an error. If you change the input line `a=3+foo;` to `a =...

Github now has "fine-grain personal access tokens" for read-only access to artifacts. It's in "beta", but it works. I'm now moving forward with changes in grammars-v4 to do the indexing...

> @kaby76 I merged #3880 so maybe try the latest dev branch? This works great. The Go target is roughly 2x the CSharp parse time for asm8080 and asmZ80 examples.

Sorry, it's actually still there in the current "dev" branch--tested the wrong thing. The problem is that the grammar references COMMENT on the RHS of a parser rule, and COMMENT...
