Message Hi Bob,

Thanks for following up on this. I've been swamped at work (we have a
couple fo critical deadlines coming up) and haven't had much time to spend
on the dependency graphing for Antelope.

I've inserted some comments below.

Feel free to grab any of the Antelope code that might help you out. I'm
not real concerned about licensing issues, if you need a different license
(Antelope uses the Apache license), it's not a problem for me to change.

I agree, svg is a good way to go.

I actually had 2 ideas in mind. First the gef graph would work like the
sax tree, so clicking on a target in the gef diagram would move the cursor
in the editor to appropriate line in the build file, and edits to the
build file would be reflected in the gef graph. Second, I've wanted to do
a graphical "builder" where the user could drag build file items (tasks,
targets, etc) from a list and drop them on a gef graph to create or edit a
build file. Dependencies would be created by dragging a line from one
target to another.

On file save. It can't be done on each keypress and most of the time, you
have invalid xml when you're editing.
