It also becomes an alias in the grammar file itself. For instance with %token PLUS "+" in addition to exp: exp PLUS exp you can also write exp: exp "+" exp which I find much clearer. It's probably not helpful in your case though. I would also recommend that you have a look at the documentation of api.token.prefix. > Will the token still have an integer assigned that can be used in the actions or do I get there the string as well instead of an integer? No, it’s an alias, they have a single number. > By the way, I’ll still get the error message as a string I guess, right? Yes. Some day we will work on improving error message generation, there is much demand. _______________________________________________ [email protected] https://lists.gnu.org/mailman/listinfo/help-bison
