Hi
Our DSL has some special characters need to be mapped to JVMFeature. How to custom it? Thank you.

Not sure whether I understand. Are you trying to have cross references
to Java elements whose names contain special characters? If so, the
answer is yes. You have to specify a datatype/terminal rule to match the
names of your Java elements (default is ID that does not match special
chars), e.g.

terminal MyID:
('a'..'z' | 'A'..'Z' | 'ä' | 'Ä')*;

MyFQN:
MyID ('.' MyID)*;

MyClassReferingToJvm:
ref=[JvmMember|MyID];

Thank you, Jan. I would like to develop a DSL based the Xbase. In the Xbase, '+' mapped operator_plus(String a, Object b). How to custom another mapping? For example, 'SET' mapping Foo.set() method.

There are various possibilities to extend Xbase.
It depends in What context you want to use 'SET'?
Is it a keyword or just a feature call (i.e. an identifier)
Do you want it to be a binary operator?

Please outline the syntax and the context (i.e. arguments/operands and
where/how they appear) by example.

For example:
SET PERSON1 ONLINE
SET PERSON2 OFFLINE
mapping JVMOperator Foo.set(Person person, Status status).
