A little script for boostrapping a basic ruby rbenv environment. The script installs rbenv and ruby-build from Homebrew, activates a new rbenv and then installs the rbenv-rhash and compass gems.

rbenv_bootstrap.sh

#!/usr/bin/env bash

# This script bootstraps a basic ruby rbenv environment using Homebrew
#
# Should be executed in the current shell by calling from source (or dot):
# $ source ./.rbenv
# $ . ./.rbenv


RUBY_VERSION='1.9.3-p362'

echo "Installing rbenv, and ruby-build"
brew update
brew install rbenv
brew install ruby-build

echo "Backing up .bashrc"
cp ~/.bashrc ~/$(date +.bashrc.backup_%Y_%m_%d_%H:%M:%S)

echo '

# Enable Ruby rbenv (via Homebrew)
if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi
' >> ~/.bashrc

echo "Installing Ruby $RUBY_VERSION to rbenv"
rbenv install $RUBY_VERSION
rbenv global $RUBY_VERSION

echo "Initializing rbenv"
eval "$(rbenv init -)"
