* Description
This layer adds support for [[http://clojure.org][Clojure]] language using [[https://github.com/clojure-emacs/cider][CIDER]].
* Features
- REPL via [[https://github.com/clojure-emacs/cider][CIDER]]
- Code formatting via [[https://github.com/clojure-emacs/cider][CIDER]] using [[https://github.com/weavejester/cljfmt][Cljfmt]]
- Refactoring via [[https://github.com/clojure-emacs/clj-refactor.el][clj-refactor]]
- Aligning of code forms via [[https://github.com/gstamp/align-cljlet][align-cljlet]]
* Install
** Layer
To use this contribution add it to your =~/.spacemacs=
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-configuration-layers '(clojure))
#+END_SRC
** 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/user-config= section of your =~/.spacemacs= file:
#+BEGIN_SRC emacs-lisp
(setq clojure-enable-fancify-symbols t)
#+END_SRC
Or set this variable when loading the configuration layer:
#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-configuration-layers
'((clojure :variables clojure-enable-fancify-symbols t)))
#+END_SRC
** CIDER and clj-refactor
*** Quick Start with boot
- Install =boot= (see https://github.com/boot-clj/boot#install)
- Create a file =~/.boot/profile.boot= with the following content:
#+BEGIN_SRC clojure
(require 'boot.repl)
(swap! boot.repl/*default-dependencies* conj
'[refactor-nrepl "1.2.0-SNAPSHOT"]
'[cider/cider-nrepl "0.10.0-SNAPSHOT"])
(swap! boot.repl/*default-middleware* conj
'refactor-nrepl.middleware/wrap-refactor)
#+END_SRC
- Run ~SPC m s i~ in any of the clojure source files to connect to the CIDER REPL.
*** Quick Start with lein
- Install =lein= via your OS package manager.
- Create a file =~/.lein/profiles.clj= with the following content:
#+BEGIN_SRC clojure
{:repl {:plugins [[cider/cider-nrepl "0.10.0-SNAPSHOT"]
[refactor-nrepl "1.2.0-SNAPSHOT"]]
:dependencies [[alembic "0.3.2"]
[org.clojure/tools.nrepl "0.2.10"]]}}
#+END_SRC
- After creating your project with ~lein new app <projectname>~ or
importing an existing project, run ~SPC m s i~ in any of the clojure
source files to connect to the CIDER REPL.
*** More details
More info regarding installation of nREPL middleware can be found here:
- CIDER: [[https://github.com/clojure-emacs/cider#installation][cider_install]]

* Key Bindings
** Working with clojure files (barfage, slurpage & more)
Spacemacs comes with a special ~lisp-state~ for working with lisp code that
supports slurpage, barfage and more tools you'll likely want when working with
lisp.
As this state works the same for all files, the documentation is in global
[[https://github.com/syl20bnr/spacemacs/blob/master/doc/DOCUMENTATION.org#lisp-key-bindings][DOCUMENTATION.org]]. In general, use ~SPC k~ to interact with the lisp-state.
