When you install clojure-mode via
package-install, you can then open any
.clj file and automatically enter the mode.
And this works for every subsequent Emacs launch ; Yet, no
(require 'clojure-mode) (or a custom definition, nothing) has been inserted in the init file.
I carefully reviewed the clojure-mode.el file, and found no clue as to how this works. Yes, the main interactive functions and the major modes definitions are autoloaded, and the common clojure file extensions are added to
;;;###autoload (progn (add-to-list 'auto-mode-alist '("\\.\\(clj\\|dtm\\|edn\\)\\'" . clojure-mode)) (add-to-list 'auto-mode-alist '("\\.cljc\\'" . clojurec-mode)) (add-to-list 'auto-mode-alist '("\\.cljx\\'" . clojurex-mode)) (add-to-list 'auto-mode-alist '("\\.cljs\\'" . clojurescript-mode)))
But this is not enough for the mode I'm working on. I found no way of loading it without explicitly requiring it in the init file..?
What is this magic?
