Getting Started with Clojure and Aquamacs

2008-07-02T18:34:17-04:00

I just posted a short screencast on how to get started with Clojure and Aquamacs:

One of the fun features of Clojure, or any Lisp I suppose, is the interactive development workflow. As you can see in the video, you write code by creating expressions that define functions and then you evaluate those functions in the REPL (Read-Eval-Print-Loop). You can redefine a function at any time. You can imagine that if you had a production system running, you could connect to it via a REPL or something like that, evaluate some expressions that redefine functions that contain bugs, and the system would be fixed with no downtime.

Here's the contents of the ~/bin/clj script:

#!/bin/bash 

SRC_DIR=/Users/pbarry/src

CLOJURE_JAR=$SRC_DIR/clojure/clojure.jar
JLINE_JAR=$SRC_DIR/jline/jline-0.9.94.jar

if [ -z "$1" ]; then 
    java -cp $JLINE_JAR:$CLOJURE_JAR jline.ConsoleRunner clojure.lang.Repl    
else
    java -cp $CLOJURE_JAR clojure.lang.Script $1
fi

Very helpful. Thank you. Here is that customization.el snippet for your copy / paste pleasure:

---
(add-to-list 'load-path "~/clojure/clojure-mode")
(setq inferior-lisp-program "clj")
(require 'clojure-mode)
(setq auto-mode-alist
(cons '("\\.clj$" . clojure-mode)
auto-mode-alist))

(add-hook 'clojure-mode-hook
'(lambda ()
(define-key clojure-mode-map "\C-c\C-e" 'lisp-eval-last-sexp)))
---

Also, this may be an obvious point, but make sure the clj executable is in your path and properly CHMODed.
