Re: Clarification on setting up Clojure, Lein and Emacs on fedora

[Moritz Ulrich]

If you have a recent (24) Emacs, use M-x package-install and install
clojure-mode and nrepl. nrepl is the successor-in-spirit of slime, as
many people consider slime as deprecated. When you have access to
leiningen 2 (strongly recommended), the whole setup simplifies to:

1) Install leiningen 2 & Emacs 24
2) In Emacs: Add Marmelade repository
3) In Emacs: M-x package-install RET nrepl RET
4) nrepl-jack-in

Sayth,

Not sure I follow everything in your post, but here are some tips:

 1. You don't need to "install" Clojure itself. Leiningen takes care of that for you. See

 2. Make sure you install Emacs 24. I don't know what the Fedora incantations are for this.

 3. Once you've got Emacs 24 installed, add this to your ~/.emacs file:

    ~~~elisp
    (require 'package)
    (add-to-list 'package-archives
                 '("marmalade" . "http://marmalade-repo.org/packages/"))
    (package-initialize)
    ~~~

    and then you can have Emacs install clojure-mode (and any other Emacs packages you desire) via "M-x package-install RET <the-package-name>" (for example, clojure-mode).

 4. To get a Clojure repl in Emacs, my understanding is that slime is no longer the state of the art, and that you instead want to use nrepl.el. Some info regarding that at https://github.com/technomancy/clojure-mode (see the doc directory and wiki there too).

As far as a code beautifier, within Emacs you can select a region and then do "M-x indent-region" to autoindent everything you've selected.

Whoops, sorry, forgot to finish typing that :) : I meant to add, "See https://github.com/clojuredocs/cds/blob/master/articles/tutorials/getting_started.md ".

I believe Fedora ships with Leiningen 1.7.1, which is not what you
want. It's better to install manually, see http://leiningen.org; that
way you will get 2.x. Don't install Clojure or Contrib through your OS
package manager.

The Emacs support for Clojure is documented here:
https://github.com/technomancy/clojure-mode/blob/master/doc/index.md

Please let us know if there's anything unclear that could be improved
about that documentation; it's always helpful to get a fresh
perspective when it comes to docs.

Thank you Phil. I have just reported that leinigen 1.7 is un-installable on F18 due to a mass of broken dependencies.

Oops ok, yum remove them then as I had already installed them.

https://github.com/technomancy/clojure-mode/blob/master/doc/index.md will read and let you know if I find anything that could be improved.

Actually I just updated the Emacs tutorial on clojure-doc.org last
night, so this might be a better resource if you're looking for
something more in-depth:
