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
JLine 1.0 is also availalbe to use with the REPL and can be downloaded from the same location as JLine 0.9.94
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
