How to override Error Messages [message #1738963]

Hi,

i want to change the automatically generated error messages but I don't really get how it works. I've just read that there's the way over the ISyntaxErrorMessageProvider but I am not sure how to implement it.
Can someone maybe please give me an example for the following rule?
How do I get the right context, when e.g. name starts with a Capital?

Dcl_var:
   'var' type=Type name=ID_VAR ;
terminal ID_VAR: 
   (('a'..'z') ('a'..'z' | 'A'..'Z' | '0'..'9' | '_')*) | '_' ;

Thanks in advance!

Or maybe someone can give me a hint where I can find an implementation where I can look at? I haven't found one on the example projects..

this this depends highly on the grammar. in your case i would loosen the grammar and do the checkin inside a valueconverter.
if you insist on implement ISyntaxErrorMessageProvider you shoudl have a look at the context and see if you can find out if you are in this situation
