I use Eclipse a lot with Java, but more recently even for Perl.

There have long been c++/perl plugins for Eclipse, but with Callisto, it has been so easy to get most of them installed out of the box, that I had more time to look at other plugins out there.

One interesting plugin/IDE for Eclipse is
EPIC - Eclipse Perl Integration

Normally, I use textpad or vi(m), depending on whether I am on windows or unix. But I really like not having to configure perl-tidy or whatnot into the editor. In fact, I am so lazy and end up on so many different machines, I just use the default settings with vi anyway.

In all this, I am addicted to source code formatters, like what Eclipse has built-in for Java. I don't have to worry about whether there are tabs or spaces or whether I missed indentation in a couple of spots. EPIC has PerlTidy built-in - you just have to make sure the Perl interpreter is configured.

What have your experiences been? Have you tried EPIC? How does it compare to commercial IDE's like Komodo?
