Re: [cedet-semantic] Constructing the semantic parse tree

[Eric M. L. <er...@si...>]

Hi Thomas,

So you know, there is an erlang parser already in the 
semantic/bovine/erlang.by parser.  As far as I know, it parses, but we 
don't have much in the way of tests, etc.

To do what you are looking to work on, check:
http://cedet.sourceforge.net/addlang.shtml

and I think you would need Step 2, 4, and perhaps 5.  Step 5 helps get 
the context analyzer up which is useful for refactoring.

Since there are pretty good defaults already for 2,4, and 5, the work 
there might be easy.  (ie - a small # of things to overload.)

After then, look at semantic/symref.el and semantic/symref/* which is a 
simple framework from which some kinds of refactoring can take place. 
At the moment, just renames is done.

If you make some big changes and would like to contribute to CEDET, you 
will need to sign papers with the FSF for contributions to Emacs and 
CEDET.  If you are interested, I can send you the form.

Good Luck
Eric
