Descrizione

I am thinking something along the lines of https://omrelli.ug/nearley-playground/ that provides an interactive feedback to the user creating a grammar, via examples or other way. The nicest tool I know is about regular expressions only : https://regex101.com/

Is there something like that for parser grammars ? where we could just add lark syntax?

I am not used to write parser grammars, and I am currently doing this in a python interpreter. The raw python error messages can be quite cryptic for a newcomer. Any idea ? Am I missing an obvious tool here ?
