LGTM! I am able to validate the parser during cli-runtime by using the following setup:
A: B | C;
B: 'a' 'b' 'c' 'd' 'e' 'f' id=STRING;
C: 'a' 'b' 'c' 'd' 'e' 'g' id=STRING;
Which will result in the following error being shown in the console:
Error: Parser Definition Errors detected:
Ambiguous Alternatives Detected: <1 ,2> in <OR1> inside <A> Rule,
<a, b, c> may appears as a prefix path in all these alternatives.
See: https://chevrotain.io/docs/guide/resolving_grammar_errors.html#AMBIGUOUS_ALTERNATIVES
