Dynamic Search Tool

Do you have a question? Post it now! No Registration Necessary.  Now with pictures!

Hi folks,

I've been dabbling with Perl for some weeks now to build some tools for
use at work. I'm now looking to produce a simple search tool that will
extract a list of variable names from a given file (or set of files)
then dynamically sort this list of names as a user enters a search
string. It will be incorporated into a small Tk application that i'm
working on and at the moment I envisage using an entry field with each
keystroke bound to a reqexp match routine which repopulates the
displayed list from the master list on each key stroke.

Now, simply put, has anyone ever attempted this before? I'm concerned
that the binding to a key stroke event on the entry field will not
produce very fast results.

Thanks in advance for any advice
