Setting up Clojure 1.1.0 on Mac OSX

As part of the Lambda Lounge, established by Alex Miller (Thanks!!), we have started a group to study the SICP. We just started and are going virtual... if you would like to participate, email or tweet me (@kensipe). In the process of studying SICP and LISP, I plan on focusing on Clojure. Clojure was previously on my machine as I was reading Stu's book Programming Clojure, however increased usage would require some maturing of my tools. This led to the discovery of Mark Reid's blog on Setting up Clojure for Mac OS X, however I assume based on updates and changes over the last year, it requires some updates.

Read Mark's blog first... getting clojure, the clojure-contrib and jline. Here are the differences:

• Create an environment variable CLOJURE_HOME assigned to the directory for clojure
• Create the /bin directory for the clj script included below
• Add $CLOJURE_HOME/bin in the $PATH
• Clojure is distributed with clojure.jar in the CLOJURE_HOME... so I maintain that. It is expected that contrib and jline are in the same directory.
• Mark's clj script has been updated below... The previous script invokes classes which are depreciated.
  

Here is the updated script:

#!/bin/bash
# Runs Clojure using the classpath specified in the `.clojure` file of the
# current directory.

#
# This scripts expects $JAVA_HOME and $CLOJURE_HOME to be defined for the system it is running on
# The clojure.jar is standardly in the clojure_home dir (and not in the lib directory), so
# the expectation is that clojure-contrib.jar and the jline.jar are placed in the same dir

CLJ_DIR=$CLOJURE_HOME
CLOJURE=$CLJ_DIR/clojure.jar
CONTRIB=$CLJ_DIR/clojure-contrib.jar
JLINE=$CLJ_DIR/jline-0_9_5.jar
CP=$PWD:$CLOJURE:$JLINE:$CONTRIB

# Add extra jars as specified by `.clojure` file
if [ -f .clojure ]
then
   CP=$CP:`cat .clojure`
fi

if [ -z "$1" ]; then
   java -server -cp $CP \
        jline.ConsoleRunner clojure.lang.Repl
else
   java -server -cp $CP clojure.main -i $*
fi

Love the TextMate support and the history support in JLine!
