Description

This layer adds support for Clojure language using Cider.

Features

• REPL via Cider
• Refactoring via clj-refactor
• Auto completion via ac-cider
• Automatic formatting via align-cljlet

Install

Layer

To use this contribution add it to your ~/.spacemacs

  (setq-default dotspacemacs-configuration-layers '(clojure))

Pretty Symbols

Pretty symbols for anonymous functions, set literals and partial, like (λ [a] (+ a 5)), ƒ(+ % 5), ∈{2 4 6} and Ƥ.

To enable this feature, add the following snippet to the dotspacemacs/config section of your ~/.spacemacs file:

  (setq clojure-enable-fancify-symbols t)

Or set this variable when loading the configuration layer:

  (setq-default dotspacemacs-configuration-layers
  '((clojure :variables clojure-enable-fancify-symbols t)))

Cider and clj-refactor

Quick Start with lein

• Install lein via your OS package manager.
• Create a file ~/.lein/profiles.clj with the following content:

  {:user {:plugins [[cider/cider-nrepl "0.9.0-SNAPSHOT"]
                    [refactor-nrepl "0.3.0-SNAPSHOT"]]
          :dependencies [[alembic "0.3.2"]
                         [org.clojure/tools.nrepl "0.2.7"]]}}
