I recently looked into some alternatives to Rubymine, for doing some (Ruby) side projects. I mostly use Rubymine at work, so I thought it would be a good idea to familarize myself with another IDE. While I have used editors to work on Ruby, in particular Atom and Sublime and heard that Vim (plus plugins) is another popular choice, I wanted to see what is out there. To make it short how my search ended: I will use Atom, for the time being, once I get to do something with Ruby. (First I will rather work on this blog and a project for which I like to use Jekyll, or another static site generator though.) The Ruby ecosystem seems to no longer have supported a variety of IDEs anymore in recent years. You do find quite a few discontinued projects though and others which no longer have full support.
