On Friday the 17th of October, Apple released OSX Yosemite. Being a bit of an Apple fanboy I immediately set about upgrading my main system (which happens to be a Hackintosh). This is a post mostly to remind myself about how I went about it and some of the potentially interesting things I do with my setup.

not yosemite Not Yosemite - It's Kicking Horse!

  1. ZSH

With Yosemite I dumped oh-my-zsh. I did this because I found it a little too slow with some preferences that I didn't appreciate. I replaced it with the standard zsh and Antigen which is a vundle-inspired plugin manager for zsh. You can see my setup for it in my dotfiles.

  1. Dotfiles

I decided to actually clean up my dotfiles and put them all into a single repository. Eventually I hope to have a simple setup script, but right now you can simply clone the repo then do a few symlinks for gitignore, direnvrc, tmux.conf, vimrc, and zshrc.

still not yosemite Nope, that's Yellowstone

  1. Global Gitignore

I added a global .gitignore file to my dotfiles which can be setup with the following .gitconfig section

[core]
	excludesfile = ~/.gitignore

This means that I'll never accidentally commit .DS_Store!

  1. chruby and ruby-install and direnv

I've written previously about chruby but I no longer use any type of gemset or auto-switching functionality in chruby. Instead I use direnv which is a tool to setup .envrc files for specific folders. These can be used to set environment variables for each folder or, as in my case, switch to the proper ruby.

One trick I use for this is the following snippet of code:

# use ruby [version]
use_ruby() {
  local ver=$1
  if [[ -z $ver ]] && [[ -f .ruby-version ]]; then
    ver=$(cat .ruby-version)
  fi
  if [[ -z $ver ]]; then
    echo Unknown ruby version
    exit 1
  fi
  chruby $ver
}

I put this into my .direnvrc file (inside home) and then if I want a particular .ruby-version I create a project specific .envrc file like this:

use ruby $(cat .ruby-version)
export PATH=$PWD/bin:$PATH

This file causes direnv to read the .ruby-version file and run chruby $ruby-version setting up ruby correctly. It also adds the .bin folder to the front of the PATH which means that I don't need to run bundle exec for Rails applications since I'm just using the binstubs.

To assist me in creating this .envrc file everywhere I need it I created a really simple Antigen plugin: chruby-direnv

yosemite Okay, this is Yosemite

  1. Homebrew Cask

Cask is a cool extention to homebrew which means you can install lots of regular apps right from the command line. Stuff like Skype, Dropbox, Chrome, Rdio and thousands of others are available simply by typing:

brew cask install <program>

yosemite And so is this
