zprint-mode.el

June 17, 2024 · View on GitHub

Integrates zprint, the pretty-printer for Clojure(Script) files, into Emacs

zprint-mode reformats files quickly (<100ms) because it uses precompiled native binaries of zprint. It works on macOS or Linux.

Changelog

Upgrade to zprint 1.2.9

Upgrade to zprint 1.0.0

Detect python executable

Upgrade to zprint 0.5.3

Fix Python 3 compatibility

Initial release

The recommended way is to use MELPA. If MELPA is in your package-archives, do

M-x package-install RET zprint-mode RET

If you use Spacemacs, you can add zprint-mode to dotspacemacs-additional-packages and use SPC f e R to reload the packages.

See below for manual installation instructions.

Filter the current buffer through zprint my invoking M-x zprint.

If a region is selected, only that region will be pretty-printed.

You can set up a keyboard shortcut if that's your thing:

(global-set-key (kbd "C-c p") 'zprint)

Or if you're running Spacemacs or otherwise using Evil mode:

(evil-leader/set-key "op" 'zprint)

Alternatively, you can enable zprint-mode in the current buffer. With zprint-mode enabled, the current buffer is auto-formatted whenever you save.

M-x zprint-mode

If you're feeling adventurous, you can enable zprint-mode for all Clojure(Script) files:

(add-hook 'clojure-mode-hook 'zprint-mode)
(add-hook 'clojurescript-mode-hook 'zprint-mode)

Download zprint-mode.el and save it somewhere where emacs can find it, e.g. ~/.emacs.d/lisp/.

You only need zprint-mode.el - the zprint graalvm binary is downloaded automagically on first run.

You will probably need to add that directory to Emacs's load path:

# e.g.
(add-to-list 'load-path "~/.emacs.d/lisp/")

Then you will need to require the package:

(require 'zprint-mode)
