Cider jack-in with tools.deps

cider+deps.md

Instructions

Note: you must have Cider version 0.18.*

For pure tools.deps (non-lein)

In deps.edn

{:paths ["src" "resources"]
 :deps {org.clojure/clojure {:mvn/version "1.9.0"}}
 :aliases
 {:cider-clj {:extra-deps {org.clojure/clojure {:mvn/version "1.9.0"}
                           cider/cider-nrepl {:mvn/version "0.18.0"}}
              :main-opts ["-m" "nrepl.cmdline" "--middleware" "[cider.nrepl/cider-middleware]"]}}}

In Emacs:

(setq cider-clojure-cli-global-options "-R:cider-clj")

Now cider-jack-in will launch nrepl and connect.

For a leiningen project

(defproject day-of-datomic "0.1.0-SNAPSHOT"
  :plugins [[lein-tools-deps "0.4.1"]]
  :middleware [lein-tools-deps.plugin/resolve-dependencies-with-deps-edn]
  :lein-tools-deps/config {:config-files [:install :user :project]})

Note: now you remove the :dependencies key, as they are all in your deps.edn file

Follow the above snippets for this simple stuff.

If you want to launch nrepl server yourself, you can do this but I wanted less steps.

There is also an inf-clojure package which understands tools.deps if you want something closer to inferior-lisp.
