If you want to load your tokens from a text file, I'm not sure that will work since the tokens get compiled into the grammar. Really, I haven't worked in this area for years so I would recommend checking out Terrence Parr's antlr book for the best info. @Julie: Honestly I’m not sure exactly what you’re asking.

can we put it all in a string, like this ” ‘student’ | ‘pupil’ | ‘teacher’ ” (not include quote), into NOUN to make it understand in stead of define each word to the grammar file?

Could you please tell me the procedure about how to use antlr with eclipse. I tried a lot but failed. Thanks Swathy Hi Alex

I understand that you’re using antlr with eclipse. Could you please tell me the procedure about how to use antlr with eclipse. I tried a lot but failed.

Thanks

Thanks for the catch. All the backslashes fell out in some escaping or encoding along the way. Should be fixed now. Absolutely right! Thanks for the catch.
