Requesting some enhancements
This is my first mail to the list. Thanks for the cool tool set. Bless you for separating the actions/semantics from the grammar/syntax. Perhaps you could add a few diagnostic aids in a future release. There are two aids that I would appreciate.
1) When I have a syntax error, while running my parser, I see a message somewhat like:
[line number, column number] [list of allowable tokens] "expected."
Could you add the token received to this message? Sort of like:
[line number, column number] "Got" [token] ", expecting one of" [list of allowable tokens]
2) When generating my lexer, could you emit a warning when a token will never occur? For example, given:
word = ([a..z] + [A..Z])+;
keyword = 'KEY';
it would be great if SableCC could say something like:
"Warning: TKeyword is hidden behind TWord"
With my repeated thanks,
