My set up for Clojure on Mac OS X Leopard.
I've detailed much of this set up in a blog post but here's the short, command-line by command-line version:
Clone a copy of this project to your ~/Library/ directory:
$ cd ~/Library
$ git clone git://github.com/mreid/clojure-framework.git Clojure
$ cd Clojure
Create a directory lib:
$ mkdir -p ~/Library/Clojure/lib
Grab the latest release of Clojure and put the jar in the lib directory:
$ curl http://clojure.googlecode.com/files/clojure_20090320.zip > /tmp/clojure.zip
$ unzip /tmp/clojure.zip -d /tmp/
$ cp /tmp/clojure/clojure.jar lib/
Next, get JLine to make Clojure's interactive mode nicer:
$ curl http://internode.dl.sourceforge.net/sourceforge/jline/jline-0.9.94.zip > /tmp/jline.zip
$ unzip /tmp/jline.zip -d /tmp/
$ cp /tmp/jline-0.9.94/jline-0.9.94.jar lib/jline.jar
Make the clj script executable and link to it from somewhere in your $PATH. (I use ~/bin and have added it to my $PATH in my ~/.bash_profile):
$ chmod u+x clj
$ ln -s ~/Library/Clojure/clj ~/bin/clj
This next steps are optional. Only do them if you want to use libraries from clojure-contrib:
$ git clone git://github.com/kevinoneill/clojure-contrib.git /tmp/contrib
$ cd /tmp/contrib
$ ant -Dclojure.jar=$HOME/Library/Clojure/lib/clojure.jar
$ cp clojure-contrib.jar ~/Library/Clojure/lib/
The clj command can be used to open an interactive session:
$ clj
Clojure
user=>
or it can be used to run a script:
$ clj test.clj
Hello, Clojure!
To add extra jar files to the Clojure's classpath on a project-by-prject basis, just create a .clojure file in the project's directory with the text to add to the classpath.
For example, in my ~/code/clojure/cafe project directory, I can add the Grinder and Frother jars from the ~/code/clojure/cafe/lib directory by putting their relative paths, separated by a colon, into a .clojure file:
$ cd ~/code/clojure/cafe
$ echo "lib/grinder.jar:lib/frother.jar" > .clojure
