Install

Spacemacs will prompt to install the Clojure layer automatically when opening a file ending in .clj .cljs, .cljc or .edn. Replying y will download all the packages for the Clojure layer. Restarting Spacemacs, SPC q r, is recommended to ensure all changes are loaded.

Add the Clojure Layer manually

Edit the ~/.spacemacs file and add the word clojure to the existing dotspacemacs-configuration-layers list.

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:

  (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)))

Optional LSP server

Traditionally the clojure developing environment is working exclusively with an external server called CIDER. This has some drawbacks especially that most features require a working REPL session in the background. Newer layers work with a standard LSP server providing standard bindings for most features. In addition lsp-UI provides a more modern UI for visualising linter results and providing code actions.

The server is automatically activated when you have the lsp-layer installed in your dotfile. Alternatively you can force a certain backend by setting the clojure-backend variable in your dotfile:

  (setq-default dotspacemacs-configuration-layers
  '((clojure :variables clojure-backend 'lsp)))

The server is started automatically when a supported file is opened. It will also provide a flycheck integration via lsp-flycheck which will run the configured linter from your project config. See here for details. The server is installed automatically in your emacs directory however if this does not work it can also be installed manually from here.

You can also explicitly disable lsp support by setting cider as backend explicitly:

  (setq-default dotspacemacs-configuration-layers
  '((clojure :variables clojure-backend 'cider)))

Enabling Automatic Linting

clj-kondo, joker and squiggly-clojure provide automated linting via flycheck. These packages are disabled by default as they require the relevant linter binaries to be installed locally.

The recommended linter is to use clj-kondo in combination with joker. Together they catch the most issues while both running extremely quickly.

squiggly reloads your code on every change which gives unexpected results if your code is not re-loadable. squiggly also requires org.clojure/core.typed be added to the development dependencies of your projects or build tool when using cider-connect.

Enable clj-kondo linter

This linter based on static syntax checking and requires the clj-kondo binary installed on the system PATH that spacemacs.env includes. Please read the clj-kondo binary installation instructions

Enable the clj-kondo automatic linter in Spacemacs by adding a :variables option to your Spacemacs configuration:

  ;; Witout any variables your configuration would just include clojure
  dotspacemacs-configuration-layers
  '(...
    clojure
    )

  ;; to use clj-kondo as a linter, add this variable to the clojure layer
  ;; wrapping the clojure layer in a list
  dotspacemacs-configuration-layers
  '(...
    (clojure :variables
             clojure-enable-linters 'clj-kondo)
    )

Enable joker linter

This linter is based on static syntax checking and requires the joker binary installed on the system PATH that spacemacs.env includes. Please read the joker binary installation instructions

Enable the joker automatic linter in Spacemacs by adding a :variables option to your Spacemacs configuration:

  ;; Witout any variables your configuration would just include clojure
  dotspacemacs-configuration-layers
  '(...
    clojure
    )

  ;; to use joker as a linter, add this variable to the clojure layer
  ;; wrapping the clojure layer in a list
  dotspacemacs-configuration-layers
  '(...
    (clojure :variables
             clojure-enable-linters 'joker)
    )

Enable Squiggly linter

squiggly-clojure uses Eastwood and Kibit for linting. Please install these projects before configuring Spacemacs with squiggly.

Make sure to read the squiggly-clojure warnings section.

Please read the section on squiggly dependencies if you are using cider-connect

Enable the squiggly (eastwood, kibit and core.typed) automatic linter in Spacemacs by adding a :variables option to your Spacemacs configuration:

  ;; Without any variables your configuration would just include Clojure
  dotspacemacs-configuration-layers
  '(...
    clojure
    )

  ;; to use squiggly as a linter, add this variable to the clojure layer
  ;; wrapping the clojure layer in a list
  dotspacemacs-configuration-layers
    '(...
      (clojure :variables
               clojure-enable-linters 'squiggly)
      )

Troubleshooting: please read debugging and bug reporting and try to reproduce using the sample project.

Enable multiple linters

You can choose to enable multiple linters and have them all run together. This gives you better linting coverage, as they don't catch all the same issues.

You will need to follow their individual install instructions first, to get all their necessary binaries and configs on the system PATH that spacemacs.env includes. Please refer to their individual Enable … linter section respectively.

Once all the linters you want to enable are installed, you simply need to specify a list of them in the :variables option to your Spacemacs configuration:

  ;; Witout any variables your configuration would just include clojure
  dotspacemacs-configuration-layers
  '(...
    clojure
    )

  ;; to enable multiple linters, say clj-kondo and joker, add a list variable to the clojure layer
  ;; listing each one in the order you want them running, wrapping the clojure layer in a list
  dotspacemacs-configuration-layers
  '(...
    (clojure :variables
             clojure-enable-linters '(clj-kondo joker))
    )

Enable Clojure fancify Symbols

Fancify symbols re-writes your code and displays symbols for:

function definitions with fn (λ [a] (+ a 5)) and its syntax shortcut ƒ(+ % 5)
set literals ∈{2 4 6}
partial functions Ƥ.

To enable this feature, add the following snippet to the dotspacemacs/user-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)))

Enabling sayid or clj-refactor

The packages sayid (Clojure debugger) and clj-refactor (automatic refactorings) are disabled by default. These packages are less active that the CIDER project and may cause issues when running CIDER.

To enable them, add a :variables option when enabling the clojure layer, specifying clojure-enable-sayid, or clojure-enable-clj-refactor, or both.

In your Spacemacs configuration:

  ;; before
  dotspacemacs-configuration-layers
  '(...
    clojure
    )

  ;; after
  dotspacemacs-configuration-layers
  '(...
    (clojure :variables
             clojure-enable-sayid t
             clojure-enable-clj-refactor t)
    )

Enabling either of these packages will cause extra nREPL middleware to be injected when jacking in CIDER.

If you are experiencing issues when running a REPL, try disabling these packages first and restart Spacemacs to see if the error persists.

Usage

Read the key bindings section to see all the functionality available, or simply use the , or SPC m to open the which-key menu for the Clojure layer.

Starting a REPL from Spacemacs

Open a Clojure file (.clj, .cljs, .cljc, .edn) and start a Clojure REPL, choosing the REPL session type (Clojure, ClojureScript or both Clojure & ClojureScript).

, ' and , s i calls the sesman-start command, a wrapper for all the jack-in and connect commands. A prompt appears allowing you to choose the type of REPL session required.

, s j opens the cider-jack-in menu, providing commands to start specific REPL sessions, it is the same as using the sesman-start command described previously.

Using the universal constant, SPC u before any of the previous commands enables editing of the command that starts the REPL. This is useful if you want to add a deps.edn alias or add your own dependencies to inject. The command is edited in the mini-buffer

Once the REPL starts, a confirmation message is displayed in the mini-buffer.

The REPL buffer does not open automatically (Clojure is typically evaluated in the source code buffer). , s a will switch between REPL and source code buffers, opening the REPL buffer if not already shown.

Troubleshooting

If the REPL does not start, SPC b m opens the message buffer and should show errors. Also check the REPL buffer, , s a for error messages.

Remove optional features from the Clojure layer, specifically sayid and clj-refactor. Restart Emacs and confirm the issue still occurs.

Visit #cider channel on Clojurians Slack community for help with CIDER, and #spacemacs channel for Spacemacs specific help

Connecting to a Clojure REPL outside of Emacs

Start a REPL outside of Emacs that includes an nREPL server. The IP address and port the nREPL runs on should be printed.

, '_ or SPC m s i displays the sesman prompt, select the connect command relevant to the type of REPL you wish to start.

, s c opens the cider-connect menu, providing key bindings for connecting too the different REPL session types.

CIDER communicates with your Clojure process through nREPL and for CIDER to function correctly extra nREPL middleware is needed (cider/cider-nrepl). The same is true for clj-refactor (refactor-nrepl), and for sayid (com.billpiel/sayid).

When starting the Clojure process through cider (cider-jack-in and friends) this will be handled automatically, and so most users should be able to just run SPC m s i to connect to the CIDER REPL and skip the rest of this section.

If you are running an older version of CIDER (0.10 or older), or if you are starting the Clojure process yourself outside of Emacs, then you need to make sure the necessary dependencies are present, and the necessary nREPL middlewares are enabled.

Quick Start with boot

Install boot 2.8.2 or newer (see https://github.com/boot-clj/boot#user-content-install)

Create a file ~/.boot/profile.boot with the following content:

  (require 'boot.repl)

  (swap! boot.repl/*default-dependencies* conj
         ;; When running an older version of CIDER (pre 0.18), use the
         ;; version that best matches M-x cider-version. For versions since
         ;; 0.18.0 use whatever version is the most recent.
         '[cider/cider-nrepl "0.21.1"]

         ;; Only necessary when using clj-refactor
         '[refactor-nrepl "2.4.0"]

         ;; Only necessary when using sayid
         '[com.billpiel/sayid "0.0.17"])

  (swap! boot.repl/*default-middleware* conj
         'cider.nrepl/cider-middleware
         'refactor-nrepl.middleware/wrap-refactor
         'com.billpiel.sayid.nrepl-middleware/wrap-sayid)

Quick Start with lein

Install lein version 2.9.0 or newer (see https://leiningen.org/#install)

Create a file ~/.lein/profiles.clj with the following content:

  {:repl
   {:plugins [;; When running an older version of CIDER (pre 0.18), use the
              ;; version that best matches M-x cider-version. For versions since
              ;; 0.18.0 use whatever version is the most recent.
              [cider/cider-nrepl "0.21.1"]

              ;; Only necessary when using clj-refactor
              [refactor-nrepl "2.4.0"]

              ;; Only necessary when using sayid
              [com.billpiel/sayid "0.0.17"]]

    :dependencies [[nrepl "0.4.5"]]

    :repl-options
    {:nrepl-middleware [refactor-nrepl.middleware/wrap-refactor ;; clj-refactor
                        com.billpiel.sayid.nrepl-middleware/wrap-sayid ;; sayid
                        ]}}}

Managing REPL connections

Sesman is used for managing REPL connections when working simultaneously on multiple projects or have multiple connections opened for the same project

SPC m m i provides information about the current REPL. SPC m m b shows information about all REPLs currently active. SPC m m l menu links files, directories and projects to an existing session.

See REPL connections in the key bindings section for all the commands.

Advanced help

This layer installs the helm-cider package which provides helm integration with cider apropos. It also embeds cider cheatsheet.

Type SPC m h a to display advanced apropos window. Type SPC m h c to display the cheatsheet then type in some terms (space separated) to narrow down the list. For example, try typing in "sort map" to see some functions that deal with sorting maps.

NOTE: If helm is not used, then cider-apropos and cider-cheatsheet are used.

Structuraly safe editing

The Clojure layer adds support for evil-cleverparens which allows to safely edit lisp code by keeping the s-expressions balanced.

SPC m T s will toggle safe structured editing, off by default.

Enable safe structural editing for all clojure buffers using the following in the dotspacemacs/user-config function of your .spacemacs file

  (spacemacs/toggle-evil-safe-lisp-structural-editing-on-register-hook-clojure-mode)

Or enable safe structural editing for all supported modes:

  (spacemacs/toggle-evil-safe-lisp-structural-editing-on-register-hooks)

When enabled the symbol 🆂 will display in the mode-line.

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 DOCUMENTATION.org. In general, use SPC k to interact with the lisp-state.
