Rubyist OS X Dev setup

Posted: May 30, 2010 | Author: carlosgabaldon | Filed under: Uncategorized | Tags: os_x, ruby, software development | 1 Comment »

I just bought a shiny new MacBook Pro with a 2.4 GHz Core i5, 8 GB Memory, on OS X 10.63 and thought I would share my setup.

TextMate

Head over to http://macromates.com/ and download TextMate. Once we have installed TextMate we are going to configure it. From the TextMate menu go to:

TextMate >> Preferences >> Fonts & Colors. Then select the “Twilight” theme.

For smaller projects where we do the markup ourselves we are going to use Haml, which we will install shortly, TextMate does not include this bundle by default, so we need to add it. Open up terminal and enter the following:

cd /Applications/TextMate.app/Contents/SharedSupport/Bundles
svn co "http://svn.textmate.org/trunk/Bundles/Ruby%20Haml.tmbundle/"

Back in TextMate go to Bundles >> Bundle Editor >> Reload Bundles.

Terminal

Next on our list is to configure Terminal.

The first thing we want to do is setup the bash prompt for Git. This cool trick will show our checked out topic branch right at the prompt:

Open a Terminal session and type the follow:

sudo mate ~/.bash_login 

To configure we will copy the following into our .bash_login file:

   RED="\[33[0;31m\]"
     YELLOW="\[33[0;33m\]"
 	  GREEN="\[33[0;32m\]"
       BLUE="\[33[0;34m\]"
  LIGHT_RED="\[33[1;31m\]"
LIGHT_GREEN="\[33[1;32m\]"
      WHITE="\[33[1;37m\]"
 LIGHT_GRAY="\[33[0;37m\]"
 COLOR_NONE="\[\e[0m\]"

function parse_git_branch {

  git rev-parse --git-dir &> /dev/null
  git_status="$(git status 2> /dev/null)"
  branch_pattern="^# On branch ([^${IFS}]*)"
  remote_pattern="# Your branch is (.*) of"
  diverge_pattern="# Your branch and (.*) have diverged"
  if [[ ! ${git_status}} =~ "working directory clean" ]]; then
    state="${RED}⚡"
  fi
  # add an else if or two here if you want to get more specific
  if [[ ${git_status} =~ ${remote_pattern} ]]; then
    if [[ ${BASH_REMATCH[1]} == "ahead" ]]; then
      remote="${YELLOW}↑"
    else
      remote="${YELLOW}↓"
    fi
  fi
  if [[ ${git_status} =~ ${diverge_pattern} ]]; then
    remote="${YELLOW}↕"
  fi
  if [[ ${git_status} =~ ${branch_pattern} ]]; then
    branch=${BASH_REMATCH[1]}
    echo " (${branch})${remote}${state}"
  fi
}

function prompt_func() {
    previous_return_value=$?;
    # prompt="${TITLEBAR}$BLUE[$RED\w$GREEN$(__git_ps1)$YELLOW$(git_dirty_flag)$BLUE]$COLOR_NONE "
    prompt="${TITLEBAR}${BLUE}[${RED}\w${GREEN}$(parse_git_branch)${BLUE}]${COLOR_NONE} "
    if test $previous_return_value -eq 0
    then
        PS1="${prompt}➔ "
    else
        PS1="${prompt}${RED}➔${COLOR_NONE} "
    fi
}

PROMPT_COMMAND=prompt_func

Next let’s make terminal a little prettier. From the Terminal menu:

Terminal >> Preferences >> Startup; New window settings: "Homebrew".
Terminal >> Preferences >> Settings; Font select "Andale Mono 18pt".

Now that we have TextMate and Terminal configured we are going to setup our development tools.

Development Tools

XCode Tools

Go to http://developer.apple.com/mac/ and download the latest version of XCode. Once it is downloaded simply run the installer.

Git

Next we will download the git-osx-installer, then run it.

RubyGems

From terminal we need to update our RubyGems:

sudo gem install rubygems-update
sudo update_rubygems

SSH

Still at terminal we will run:

ssh-keygen -t rsa -C "cgabaldon@gmail.com"
cat ~/.ssh/id_rsa.pub | pbcopy

GitHub

Then we will navigate over to GitHub.com >> Account Settings to add our RSA key that we copied to the clipboard.

MySQL

We are next heading over to download mysql-5.1.47-osx10.6-x86_64.dmg, and then once downloaded run the installer.

After MySQL is installed we will install the MySQL preference pane which gets added to the OS X System Preferences. To install we simply double clicking on the MySQL.prefPane contained within the MySQL install package. This gives us a convenient way to start and stop our MySQL server from the System Preferences.

Back to terminal to add our newly installed MySQL server to our path:

cd
sudo mate .bash_login # add: export PATH=/usr/local/mysql/bin:$PATH

Then last, but not least we need to install our ruby mysql gem:

sudo gem install mysql -- --with-mysql-config=/usr/local/mysql/bin/mysql_config

Sinatra

sudo gem install sinatra

Rails

sudo gem install rails

Other Gems

sudo gem install sequel
sudo gem install haml
sudo gem install do_sqlite3
sudo gem install cheat 
sudo gem install cucumber 
sudo gem install dancroak-twitter-search 
sudo gem install faker 
sudo gem install geokit 
sudo gem install giraffesoft-timeline_fu 
sudo gem install github 
sudo gem install heroku 
sudo gem install json 
sudo gem install mislav-hanna 
sudo gem install nokogiri 
sudo gem install passenger 
sudo gem install rack 
sudo gem install railsmachine 
sudo gem install RedCloth 
sudo gem install redgreen 
sudo gem install reek 
sudo gem install rest-client
sudo gem install right_aws
sudo gem install right_http_connection 
sudo gem install rr 
sudo gem install rspec 
sudo gem install technicalpickles-le-git 
sudo gem install thoughtbot-factory_girl
sudo gem install thoughtbot-paperclip 
sudo gem install thoughtbot-shoulda 
sudo gem install webmat-git_remote_branch 
sudo gem install webrat 
sudo gem install wirble 

Capistrano

To simplify deployment we need to install Capistrano:

sudo gem install capistrano
sudo gem install capistrano-ext

FireFox

We of course need to install FireFox, by downloading and installing.

FireBug

Then Firebug and YSlow to help us on our front end engineering work.

Quicksilver

To help us keep our hands off the mouse we will install Quicksliver so we can exercise our keyboard foo. To install simply extract the tarball and drag to Applications.

Update the mappings to be Apple+Space for Quicksilver and Option+Space for Spotlight.

Fluid

Finally, we will install Fluid to help us turn our commonly visited sites into apps. Once downloaded drag to Applications.

Virtual Box

All production applications get deployed to a LAMP server, so we need a place to test out various configurations locally. Say hello to virtualization! We are going to use VirtualBox; download and install.

Evernote

Never forget anything; install Evernote and sign up.

Concentrate

Multitasking does not work when trying program, distractions will kill you. We are going to install Concentrate to apply the Pomodoro technique to keep focused and productive.

Things

We have a lot of Things to get done, so we need a great task management tool.

Growl

Most of the cooler OSX applications support notifications, Growl is the system for doing that.

Pencil

Pencil is one of the coolest UI prototyping tools I have used since a Sharpie.

Hack

We are now ready to do some serious hacking..
