Getting rails 4 up and running with rbenv on Ubuntu 13.10

Brain dump warning!

This is a follow up to http://timwise.blogspot.co.uk/2013/05/installing-ruby-2-rails-4-on-ubuntu.html and is just a list of steps needed to get a clean install of Ubuntu up to speed with an existing site.

• Install rbenv to manage ruby versions
• https://github.com/sj26/rbenv-install
• git clone https://github.com/sstephenson/rbenv.git ~/.rbenv
• Install ruby-build to manage installation of ruby versions into rbenv
• https://github.com/sstephenson/ruby-build
• git clone https://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build
• For convenience install dotmatrix - this will set up the rbenv environment correctly, amongst other things
• clone https://github.com/timabell/dotmatrix
• run bin/install
• restart any running terminal(s) to get rbenv

• get a project (includes a .ruby-version file for rbenv, and a Gemfile for bundle)
• git clone git@github.com:timabell/symbol-library.git
• sudo apt-get install libssl-dev libreadline-dev
• readline is needed for rails console, and has to be installed before ruby. If you've already installed ruby then just re-run rbenv install and it will overwrite the existing build with a version with readline support. ref: http://vvv.tobiassjosten.net/ruby/readline-in-ruby-with-rbenv/
• rbenv install x.x.x-xxxx
• autocompletes, yay!
• .. or better still reads from .ruby-version I think so you can just run `rbenv install` if you are in the project folder
• gem install bundler
  
  • from the right directory so done for right ruby version
  • rbenv rehash
• bundle
  
  • will install all the gems for the project
• don't sudo apt-get install rbenv ~ doesn't provide sufficiently up to date ruby
• gem install rails --version 4.0.2 --no-ri --no-rdoc ~ don't need this when you have a gem file with rails in it, bundle will do it for you
• sudo apt-get install nodejs
  
  • for javascript runtime (rails server throwing an error without this)
• bundle exec rails server
• bundle exec rails console
• needs readline (see above)

Other stuff I like in my install

• dotmatrix bin/vimbundles
  
  • includes vim-rails and friends
  • full list https://github.com/timabell/dotmatrix/blob/master/bin/vimbundles.sh#L45
• console colours from bin/solarize.sh in dotmatrix/bin
• tmux

This is mostly for my own reference but maybe it'll help someone else out.
