Hi and thanks as always for Cdb.
I am trying to implement a function that does its work only on the "zoomed" part of an expression.
For example, please consider the algorithm posted for
expand_nabla(); a ref to that algorithm is below. I am using that algorithm and it works
But, when I zoom in on a specific term in an expression and call
expand_nabla(), the call will still expand all instances of nabla rather than just the zoomed instance.
I think that the key point is as follows. There is a loop in
expand_nabla that says
for nabla in ex[r'\nabla']:
ex[r'\nabla'] returns all instances of
\nabla but I want only the instances that appear in the zoom.
Any advice on how to change
expand_nabla() so it would be zoom-sensitive?
