Add support for xref #4

Open lokedhs opened 7 years ago

lokedhs commented 7 years ago

I don't know much about how xref providers are implemented, but the starting point is the variable xref-backend-functions which should return an xref backend that is able to find symbols in the current runtime.

Source code is documentation:

A basic Xref backend could be written that manually parses buffer for definitions, but are there any more generic tools (aside from Etags) that could provide the necessary information?

One idea I had when I started this project is that the Lisp code should be able to communicate with the inferior Forth for information. E.g. I seem to recall some Forths have built-in tools for cross referencing.
