Error messages.
Hi,
This may have already been brought up (I'm new to the mailing list), but
I think the following error message:
java.lang.RuntimeException: [21,13] identifier undefined.
should be changed to say either: token undefined or helper undefined. I
found it confusing to submit
Tokens
letter = uppercase | lowercase;
identifier = letter+
and then have the compiler complain that letter was undefined. I
finally figured out the distinction between helper/identifiers, (that
tokens can't be used in token definitions and that productions can't use
helpers), but I would have made it faster with a more explicit error
message.
Anyways, that's my complaint of the day. :)
