a no-nonsense guide to setting up an rbenv based ruby on rails development environment on OSX using homebrew, rbenv, bundler, pow, anvil note: all these commands are to be entered at the terminal

gistfile1.sh

# get homebrew http://mxcl.github.com/homebrew/
ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go)"

# remove RVM ruby manager if installed... (credit http://etehtsea.me/migration-from-rvm-to-rbenv)
rvm implode
sudo rm /etc/rvmrc
rm ~/.rvmrc

# use homebrew to install rbenv and ruby-build
brew update
brew install rbenv
brew install ruby-build

# view available rubies
rbenv install --list

# fetch a ruby
rbenv install 1.9.3-p385

# bind global
rbenv global 1.9.3-p385

# temp load rbenv context
eval "$(rbenv init -)";

# install bundler
gem install bundler

# reset shims
rbenv rehash

# verify version
ruby --version

# create ~/.bundle/config and put the following in it to create a default bundle binary compile path as [projectdir]/vendor/bundle/bin:
	---
	BUNDLE_PATH: vendor/bundle
	BUNDLE_BIN: vendor/bundle/bin

# Add the following to ~/.bash_profile (create the file if missing):
	if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi
	# add some easy terminal alias for bundler calls
	alias b="bundle exec"
	alias bi="bundle install --without production"
	# add bundler binstubs to the path so relative binarys are auto run from a project dir
	export PATH="./vendor/bundle/bin:$PATH"

# install pow (with apache proxy! so you can work alongside existing apache projects)
https://github.com/37signals/pow/wiki/Running-Pow-with-Apache

# install pow util, anvil
http://anvilformac.com/

# install rails
rbenv shell 1.9.3-p385
gem install rails
# rebuild global binary proxies
rbenv rehash

# now you can cd to your base project folder and create new rails project (optionally with mysql)
rails new projectname --database=mysql

# set default rails version for project, creates .rbenv-version
cd projectpath
rbenv local 1.9.3-p385

# run bundler install to fetch all the gems
bi

# symlink the project directory to ~/.pow
cd ~/.pow
ln -s projectpath

# view local app
http://projectpath.dev

# add bundler path to .gitignore to stop it uploading chunky binaries
/vendor/bundle

# mysql2 gem install may require editing /usr/local/Cellar/mysql/5.XX.XX/bin/mysql_config
