How to install coffee-script, and how to enable textmate bundler to compile coffeescript

gistfile1.bash

# don't forget to update your port tree first
sudo port selfupdate

# install coffee script using macport
sudo port install nodejs
node -v

# install npm - the Node Package Manager
git clone http://github.com/isaacs/npm.git
cd npm
sudo make install
npm -v

# now install coffee-script!
sudo npm install -g coffee-script
coffee -v

# because TextMate doesn't inherit your regular PATH
# you need to set a symbol link to /usr/bin
# so that you can run coffee in your textmate

which node
/opt/local/bin/node

which coffee
/opt/local/bin/coffee

cd /usr/bin
sudo ln -s /opt/local/bin/node
sudo ln -s /opt/local/bin/coffee

# install textmate coffee-script bundle
mkdir -p ~/Library/Application\ Support/TextMate/Bundles
cd ~/Library/Application\ Support/TextMate/Bundles
git clone git://github.com/jashkenas/coffee-script-tmbundle CoffeeScript.tmbundle

# now you can use command + B to compile and display javascript in your textmate!
