Example
To setup Emacs for working with Clojure, install clojure-mode and cider package from melpa:
M-x package-install [RET] clojure-mode [RET]
M-x package-install [RET] cider [RET]
Now when you open a .clj file, run M-x cider-jack-in to connect to a REPL. Alternatively, you can use C-u M-x (cider-jack-in) to specify the name of a lein or boot project, without having to visit any file in it. You should now be able to evaluate expressions in your file using C-x C-e.
Editing code in lisp-like languages is much more comfortable with a paren-aware editing plugin. Emacs has several good options.
-
pareditA classic Lisp editing mode that has a steeper learning curve, but provides a lot of power once mastered.M-x package-install [RET] paredit [RET]
-
smartparensA newer project with similar goals and usage toparedit, but also provides reduced capabilities with non-Lisp languages.M-x package-install [RET] smartparens [RET]
-
parinferA much simpler Lisp editing mode that operates mainly via inferring proper paren nesting from indentation.Installation is more involved, see the Github page for
parinfer-modefor setup instructions.
To enable paredit in clojure-mode:
(add-hook 'clojure-mode-hook #'paredit-mode)
To enable smartparens in clojure-mode:
(add-hook 'clojure-mode-hook #'smartparens-strict-mode)
