Really nice to see stories about Clojure on HN. Initially, it wasn't clear for me what editor is used but it appears to be Vim/Neovim with Fireplace: https://github.com/tpope/vim-fireplace Actually looks pretty simple and straightforward. There is a healthy choice of different editors and IDEs for Clojure right now, thanks to building on common foundations of https://github.com/clojure/tools.nrepl

In very broad strokes: The start-server command in tools.nrepl https://github.com/clojure/tools.nrepl Will open an nREPL (networked REPL) server on some port of your choosing, by default on localhost. Configure your application to allow this to happen on startup. SSH from your dev box to the server, and forward the port the REPL is listening on https://help.ubuntu.com/community/SSH/OpenSSH/PortForwarding (having the nREPL port only listen on localhost and then using SSH to access it is somewhat important for security. Someone else who connects to the nREPL port can run arbitrary code with your app's permissions, see any data being processed by your app, etc.) From a shell: lein repl :connect <port> From vim (with tim pope's fireplace plugin): :Connect nrepl://localhost:<port>

In Why Clojure?

MBlume·Nov 11, 2013

> Most of the time I need REPL-like functionalities, I need it in the heart of my application, with all its structures and state initialized and in the middle of a breakpoint. I hardly ever need to type snippets of code with zero context around them, which is what REPL's offer. This is why we Lisp developers have networked REPLs -- I can start up a remote JVM, in communication with other services, connected to my local vim session. I can dynamically load code into it, start and stop my application, etc, all from my editor. https://github.com/clojure/tools.nrepl
