After you download and unzip the latest version, you can run the Emacs executable under bin\runemacs.exe.Īfter you’ve installed Emacs, open it. Other options, like Aquamacs, are supposed to make Emacs more “Mac-like,” but they’re problematic in the long run because they’re set up so differently from standard Emacs that it’s difficult to use the Emacs manual or follow along with tutorials. OS X Install vanilla Emacs as a Mac app from.You should use the latest major version of Emacs, Emacs 24, for the platform you’re working on: Finally, you’ll learn how to actually edit Clojure code and interact with the REPL. Then you’ll learn the basics: how to open, edit, and save files, and how to interact with Emacs using essential key bindings. To get there, you’ll start by installing Emacs and setting up a new-person-friendly Emacs configuration. Emacs is also great for working with any Lisp dialect in fact, Emacs is written in a Lisp dialect called Emacs Lisp (elisp).īy the end of this chapter, your Emacs setup will look something like Figure 2-1.įigure 2-1: A typical Emacs setup for working with Clojure-code on one side, REPL on the other That kind of tight feedback loop will be useful while learning Clojure and, later, when writing real Clojure programs. The reason I recommend Emacs is that it offers tight integration with a Clojure REPL, which allows you to instantly try out your code as you write. Two alternatives that I recommend and that are well regarded in the community are Cursive and Nightcode. If you don’t follow the thorough Emacs instructions in this chapter, or if you choose to use a different editor, it’s worthwhile to at least invest some time in setting up your editor to work with a REPL. I highly recommend working with Emacs, but you can, of course, use any editor you want. On your journey to Clojure mastery, your editor will be your closest ally.
