:lang clojure

Description

This module adds support for the Clojure(Script) language.

• Interactive development environment (cider): REPL, compilation, debugging, running tests, definitions & documentation lookup, code completion, and much more
• Refactoring (clj-refactor)
• Linting (clj-kondo), requires doom-module::checkers syntax
• LSP support (clojure-lsp), required doom-module:+lsp

Maintainers

• @elken

Module flags

+lsp

Enable LSP support for clojure-mode (alongside Cider). Requires doom-module::tools lsp and a langserver (supports clojure-lsp).

+tree-sitter

Leverages tree-sitter for better syntax highlighting and structural text editing. Requires doom-module::tools tree-sitter.

Packages

• doom-package:cider
• doom-package:clj-refactor
• doom-package:flycheck-clj-kondo if doom-module::checkers syntax

Hacks

• Error messages emitted from CIDER are piped into the REPL buffer when it is first opened, to make them easier to notice.
• Disabled the help banner when opening the cider REPL.

Changelog

This module does not have a changelog yet.

Installation

Enable this module in your doom! block.

This module requires:

• clojure
• clj-kondo, for linting code (if doom-module::checkers syntax)
• clojure-lsp, for LSP support (if doom-module:+lsp)
• neil for the ability to add packages to your Clojure project from Emacs
• jet for jet integration

Usage

Below is a listing of the various keybinds provided by the module.

REPL management

For the most part, general usage should fall into:

• Open a Clojure project
• Open/connect to a REPL

As such, these bindings are most likely to be used.

Keybind	Command
<localleader> ’	cider-jack-in-clj
<localleader> c	cider-connect-clj
<localleader> C	cider-connect-cljs
<localleader> m ”	cider-jack-in-cljs
<localleader> r R	cider-restart
<localleader> r q	cider-quit
<localleader> r B	+clojure/cider-switch-to-repl-buffer-and-switch-ns
<localleader> r L	cider-load-buffer-and-switch-to-repl-buffer
<localleader> r b	cider-switch-to-repl-buffer
<localleader> r c	cider-find-and-clear-repl-output
<localleader> r l	cider-load-buffer
<localleader> r n	cider-repl-set-ns
<localleader> r r	cider-ns-refresh

Tests

The module also provides support for running tests through cider, including a nicely formatted output.

Keybind	Command
<localleader> t a	cider-test-rerun-test
<localleader> t l	cider-test-run-loaded-tests
<localleader> t n	cider-test-run-ns-tests
<localleader> t p	cider-test-run-project-tests
<localleader> t r	cider-test-rerun-failed-tests
<localleader> t s	cider-test-run-ns-tests-with-filters
<localleader> t t	cider-test-run-test

Search/navigation

Some useful bindings for navigating around namespaces and symbols. When using doom-module:+lsp, the bindings in doom-module::tools lsp are supported.

Keybind	Command
<localleader> g b	cider-pop-back
<localleader> g g	cider-find-var
<localleader> g n	cider-find-ns
<localleader> h n	cider-find-ns
<localleader> n N	cider-browse-ns-all
<localleader> n n	cider-browse-ns
<localleader> h a	cider-apropos

Evaluation

Outside of the SPC m e bindings for evaluating forms, the following are also available; including some to pretty-print the results.

Keybind	Command
<localleader> e D	cider-insert-defun-in-repl
<localleader> e E	cider-insert-last-sexp-in-repl
<localleader> e R	cider-insert-region-in-repl
<localleader> e b	cider-eval-buffer
<localleader> e d	cider-eval-defun-at-point
<localleader> e e	cider-eval-last-sexp
<localleader> e r	cider-eval-region
<localleader> p d	cider-pprint-eval-defun-at-point
<localleader> p D	cider-pprint-eval-defun-to-comment
<localleader> p p	cider-pprint-eval-last-sexp
<localleader> p P	cider-pprint-eval-last-sexp-to-comment
<localleader> p r	cider-pprint-eval-last-sexp-to-repl

Debugging

A number of bindings to provide useful overlays that help during debugging. cider-enlighten-mode is a mode that will highlight the results of a function evaluation, including the locals. See a demo here.

Keybind	Command
<localleader> M	cider-macroexpand-all
<localleader> R	hydra-cljr-help-menu/body
<localleader> e u	cider-undef
<localleader> i e	cider-enlighten-mode
<localleader> i i	cider-inspect
<localleader> i r	cider-inspect-last-result
<localleader> m	cider-macroexpand-1

Help

Several bindings used for viewing documentation for various functions, both inside and outside of both a REPL and Emacs (K for example uses the sources and a cached version of clojuredocs)

Keybind	Command
<localleader> h c	cider-clojuredocs
<localleader> h d	cider-doc
<localleader> h j	cider-javadoc
<localleader> h w	cider-clojuredocs-web
K	+lookup/documentation
