ORIGINAL SOURCE: https://gitlab.com/konrad.mrozek/cljfmt-graalvm/

A Clojure code formatter using cljfmt built with graalvm.

./cljfmt source-file.clj

For linux, a binary may be downloaded directly from Gitlab. To build the binary yourself, here are some instructions.

• Install lein
• Download GraalVM for your machine. You will need the EE version if you're using MacOS.
• Set JAVA_HOME to the GraalVM home directory, e.g.

export JAVA_HOME=~/Downloads/graalvm-1.0.0-rc1/Contents/Home

• Set the PATH to use GraalVM's binaries, e.g.

export PATH=$PATH:~/Downloads/graalvm-1.0.0-rc1/Contents/Home/bin

• Create the uberjar:

lein uberjar

• Finally, create the binary:

native-image -jar target/cljfmt-graalvm-0.1.0-SNAPSHOT-standalone.jar -H:Name="cljfmt"

Place the cljfmt binary on your PATH. To execute it on a Clojure file in Emacs on save, add this to your init.el:

(defun cljfmt ()
  (when (or (eq major-mode 'clojure-mode)
            (eq major-mode 'clojurescript-mode))
    (shell-command-to-string (format "cljfmt %s" buffer-file-name))
    (revert-buffer :ignore-auto :noconfirm)))

(add-hook 'after-save-hook #'cljfmt)
