Padre is now on Github
Perhaps you remember Padre, The Perl IDE. It was started around 5 years ago, had a lot of development, and ended up being a quite decent programmer's editor.
Alas it's been suffering from lack of care for a couple of years now. Not because of lack of need or interest, but because nobody seems to have the time. And perhaps somebody needs to step up and grab the torch. Perhaps it's you?
