Clojure Cheatsheet for Emacs
The incredibly handy Clojure Cheatsheet, updated for Clojure 1.7.0 and packaged into an easy, fast, searchable, offline form:
Ready to use. Based on Clojure 1.7.0.
If you’re hooked up to MELPA:
M-x package-refresh-contents M-x package-install RET clojure-cheatsheet
Alternatively just grab the single
clojure-cheatsheet.el file and
install that in your preferred way.
The cheatsheet doesn’t ship with keybindings - people tend to have

(eval-after-load 'clojure-mode '(progn (define-key clojure-mode-map (kbd "C-c C-h") #'clojure-cheatsheet)))
(evil-define-key 'normal clojure-mode-map "H" 'clojure-cheatsheet)
M-x clojure-cheatsheet and the cheatsheet will appear. Type

This package stands on top of Helm. The variable
helm-source-clojure-cheatsheet is available if you want to mix it in
as a Helm source.
If you like this, and you like org-mode, then you’ll probably like helm-orgcard too…
clojure-cheatsheet-hierarchy defines the contents of
the cheatsheet. See the docstring of that constant for a full
description of the format.
There is a test suite in
that checks that every symbol defined in the cheatsheet is valid, and
that every symbol defined by Clojure is in the sheet (with a few
To run the test suite:
- Clone the project.
M-x cider-jack-into start a Clojure REPL.
M-x ert <RET>to run the test suite.
- Optional: Marvel at Emacs’ support for test suites.
