Hi Fabio, I'm following along with the mailing list advice stated here:
http://www.nabble.com/PyDev-Extension-Points-Quick-Fix-%28copied-from-pydev-forum%29-tf503666.html#a1365501
where you advise extending from pydev_builder to walk the AST.
However, I'm new to Eclipse plugin programming so I wonder if you
could be a bit more specific.
Currently my plugin does something like:
public class PyGoal extends PyDevBuilderVisitor {
SourceModule sm = (SourceModule) getSourceModule(resource, document, nature);
SimpleNode sn = sm.getAst();
EasyASTIteratorVisitor vis = new EasyASTIteratorVisitor();
try{
sn.accept(vis);
} catch(Exception e) {}
}
What I'd like to do is create a simplified syntax tree structure that
just stores functions, variables, control structures, and calls. I'd
then do various specific things to that tree for my own plugin.
Can you illustrate how I would visit a particular document's AST,
putting the elements of interest in my own data structure? How do I
tell the PyDevBuilderVisitor what document/resource I'm working with?
thanks
