Hi people,
I'm new to the dltk framework. I'm using Dltk 1.0.0 release on eclipse 3.3.

We have language for which is have developed grammar in ANTLR 3.0. Now in
our language we have specific types such as label/subroutine; in which
case, these types doesnot fit into the types already provided by
SourceModule. So how do i add new types, say, Label/SubRoutine to the
SourceModule (using requestor)?

I followed the following approach:
1) I extended from SourceField to create LabelField.
2) I extended MySourceModuleRequestor from SourceModuleStructureRequestor;
but i was not able to instantiate it.
3) I inherited ISourceElementRequestor to have IMySourceElementRequestor
and added enterLabel() method. But the infostack object used is private to
ISourceElementRequestor and i cannot use it.

Is there any other approach to add your own types in SourceModule?

Please help. Thank you in advance.

~abhijit.

Hi Abhijit,

DLTK doesn't support adding of custom types to DLTK structure model.
Classes are not final because it is required by internal implementation.
They should not be subclassed.

You should map your language elements to standard elements (like type, field, method).
To provide some customization you could use modifiers.

In future versions we will provide custom renderer's for script explorer and outline, to display custom content.

Best regards,
Andrei Sobolev.

expecting the next release of dltk?
