Curious what IDE you have set up to do the REPL driven development you mentioned? I'm just starting out in learning Clojure and am finding various options out there with vigorous proponents of each. I am wondering what someone's real-world experience is after 5 years.
It's hard sometimes to find the editors/IDEs that might suite one particularly well since the vast community is attached to a given platform.
The most mature Clojure development environments right now are Spacemacs/Emacs with CIDER (free) and IntelliJ IDEA with the Cursive plugin (commercial, but inexpensive). Both are excellent.
So far I've used vim, neovim, cursive and spacemacs and all have solid repl integration. I am generally a vim/neovim user and have been using that for years. It's good. Recently, I've been using spacemacs and like it better. Cursive is pretty solid too though if you're an IntelliJ user.
I use IntelliJ with Cursive, I have had to do zero configuration, it just works with lein projects.
I will eventually switch to Spacemacs and CIDER once I've really honed my Clojure skills, but for starting out Cursive was what allowed me to learn Clojure in the first place.
Try Atom, following this admittedly opinionated guide. I think you might find it more accessible unless you're already familiar with one of the other alternatives.
