[antlr-interest] Query: customizing error messages

[Loring Craymer]

Override getTokenErrorDisplay(Token t)  (see BaseRecognizer) to index into an array of strings (or template names, if you are interested in localization); in this case, array[ID] would be the string "an identifier".

BTW, Ter--BaseRecognizer.getErrorMessage() should use templates instead of only generating English language messages ...

Subject: [antlr-interest] Query: customizing error messages


Hello,

We are developing a translator for Business-aware
language.

My query is related to Paraphrase
for customizing error messages.

We can use  paraphrases in Rules
to make error messages user-friendly, however, I could not  find a
way to replace token names with user-friendly names.
e.g.:
 mismatchedinput ';' expecting ID. In this message, I want to replace ID with "an
identifier".

ID :('a'..'z'|'A'..'Z'|'_')+('0'..'9')*
;

( options{ paraphrases = "an identifier"; } does not work. )

Any help will be highly appreciated.
Thanks.
