Hi. I’m experimenting with an online grammar development / testing / learning tool. I have a proof of concept up (just one vCPU and 4G RAM so…. haha)

http://lab.antlr.org/

It hasn’t been well tested but there is a sample split parser / lexer populated. Update parser/lexer/input/startrule and hit run. can interactively open tree and show profile info. Leave lexer tab blank and use Parser tab if you have a combined grammar.

Here is our discussion session: https://github.com/antlr/antlr4/discussions/3717
