#+TITLE: clj-java-decompiler In Emacs

Decompile your Clojure expressions from withing GNU Emacs.

• Rationale

  =clj-java-decompiler= is an awesome and useful utility.

  What would be even more awesome is if we could invoke it interactively from within Emacs and examine the results just like we do macroexpansion.

  A couple of hours of hacking later, having eaten a bit more of the world, we can.

• Install

** package.el

~M-x package-install [RET] clj-decompiler [RET]~

If the package was not found, refresh the package list via:

~M-x package-refresh-contents [RET]~

** Manual

Either:

• Put ~clj-decompiler.el~ on your load-path and require it.
• Open ~clj-decompiler.el~ and ~M-x package-install-file~.

** Spacemacs

Add ~clj-decompiler~ to ~dotspacemacs-additional-packages~.

• Usage

  • load ~clj-decompiler~ as a hook for ~cider-mode~.
  • ~(require 'clj-decompiler)~
  • ~M-x clj-decompiler-decompile~ like you would ~cider-macroexpand~.

  #+begin_src elisp (add-hook 'cider-mode-hook (lambda () (eval-after-load 'cider '(progn (require 'clj-decompiler) (clj-decompiler-setup))))) #+end_src

** Spacemacs

#+begin_src elisp (spacemacs|forall-clojure-modes m (spacemacs/set-leader-keys-for-major-mode m "ed" 'clj-decompiler-decompile) (spacemacs/set-leader-keys-for-major-mode m "eD" 'clj-decompiler-disassemble)) #+end_src
