Installing Clojure

Create and move to the directory where you want to install Java and Clojure. For example, in your $HOME directory, type the following at the command line :
```
mkdir Programs

cd Programs
```
Download the appropriate version of the JDK 1.6 into the Programs directory:
- jdk-6u26-linux-i586.bin for 32-bit Linux.
- jdk-6u26-linux-x64.bin for 64-bit Linux.
Add execution permissions to the file and run it. At the command line type:
```
chmod u+x jdk-6u26-linux-x64.bin

./jdk-6u26-linux-x64.bin
```
Download the following tarball file into the Programs directory: clojure-1.2.1.tgz. Uncompress the file, typing at the command line:
```
tar xzf clojure-1.2.1.tgz
```

Edit the .bashrc file. At the command line type:

gedit $HOME/.bashrc

Go to very end of the file and add the following lines:

export JAVA_HOME=$HOME/Programs/jdk1.6.0_26
export CLOJURE_HOME=$HOME/Programs/clojure
export PATH=$JAVA_HOME/bin:$PATH
alias clj='java -cp .:$CLOJURE_HOME/clojure.jar:$CLOJURE_HOME/clojure-contrib.jar:$CLOJURE_HOME/jline.jar jline.ConsoleRunner clojure.main'

Save the file.

Make sure your terminal window runs as a login shell. In the terminal's main menu select Edit/Profile Preferences. Select the Title and Command tab, and tick the "Run command as login shell" check-box.
Close all open terminal windows and open a new one. Verify that Clojure was installed correctly. Type at the command line:
```
clj
```
You should see the Clojure REPL (Read Eval Print Loop):
```
Clojure 1.2.1
user=>
```
Type Ctrl-D to exit the REPL.
If you use jEdit as your Clojure editor, you can use Daniel Spiewak's Clojure mode file. Just copy the clojure.xml file into jEdit's modes directory.
