How to have variable and function highlighting in UDL2.1 in Notepad++?

Question

In my language, I have variables which are either defined by dim or by prefixing it by @ (implicit variable definition).

I want to add this syntax highlighting to Notepad++, but I think for the dim, I'm out of luck. But I tried with @, and it's working, but it's highlighting the whole line (for example @Var.$id highlights everything, except what I want is everything up to the first .). How could I do this?

Example

@JobListObject = @Node.call("Instantiate", @jblistClass.$id, $self.$id);

I want Notepad++ to highlight all of the following:

• @JobListObject
• @Node (without the .call)
• @jblistClass (without the .$id)
• $self
• $id
• call()

Is there a way to do this?

Thanks!
