The "old wisdom" on comp/lang.perl.misc, when new people asked what was the best IDE to Perl programming, was "Unix".

You get both editors to choose from, vi _and_ emacs! All the man pages you could possibly want _and_ perldocs! Of _course_ as a Perl newbie you'll be able to fall back on gdb for complicated debugging where print statements no longer cut it.

I have a whole other screen for my terminal(s). The IDE already has enough going on in it.

Then you are not impeded from editing your code because it was written through a terminal process, which seems to be OP's contention.

why wouldn't you want the diffs in the IDE? Its richer and you can do more with them
