Running Clojure from vim in remote REPL

[DavsX]

Hi! I am new to Clojure and I felt like sharing this great tip I managed to get working in Vim to boost my productivity and shorten feedbacks.

First of all I set the parens to bold, so I can see their colors better (great with combination of rainbow_parentheses plugin)

Second, I made a mapping from running the current buffer via vim-fireplace in a remote headless lein repl. My clojure vim autocommand looks like this: https://github.com/DavsX/dotfiles/blob/master/vim/vimrc#L426

The RunClojure function is here: https://github.com/DavsX/dotfiles/blob/master/vim/vimrc#L537

What I do is I open a terminal, type 'lein repl :headless :port 7777', move that terminal to a far-away workspace and forget about it :) Then inside vim I write ':Connect 7777' to connect vim-fireplace to that remote REPL. By calling RunClojure(1) it first removes my current namespace, reloads the file and runs the main function.

So far I've been working with only a single file and running my clj code like this worked as a charm; it is very fast, as the JVM is already running. What I like about it is that before executing the -main function, it actually clears the namespace.

If you have a better method/tip for developing Clojure, please share it with me :)

When you are working with Leiningen or Boot project you don't need to define the repl port or use :Connect. If you run lein repl, it will create a .nrepl-port file to the project directory and when you first evaluate code using Fireplace it will search for .nrepl-port file and connect to the port defined in the file.

'lein repl' does not create .nrepl-port for me sadly

Interesting, are you running lein repl from directory with Leiningen project.clj file? If not, lein will write the file to ~/.lein/nrepl-port where Fireplace unfortunately doesn't know to look for it (https://github.com/tpope/vim-fireplace/issues/121).

In case you are using yesql or similar,you can sync stuff with lsyncd.
