Setup instructions

The following instructions will help you to get ready for Le Wagon fullstack bootcamp:

  • Grab a text editor, where you'll spend your day and nights
  • Install a package manager
  • Pimp your Terminal
  • Setup git and GitHub
  • Install Ruby

Command Line Tools

Open the Terminal (click the magnifying glass icon in the top right corner of your screen and type Terminal):

Copy-paste the following command in the terminal and hit Enter.

xcode-select --install

If you have get following message, you can just skip this step and go to next step.

# command line tools are already installed, use "Software Update" to install updates

Otherwise, it will open a window asking you if you want to install some software. Accept and wait. If it fails, try again the command line above, sometimes the Apple servers are overloaded.

While it's downloading, you can go on with configuring your GitHub account, but stop before Homebrew. You'll need the command line tools installed for that step.

GitHub account

Have you signed up to GitHub? If not, do it right away.

Upload a picture and put your name correctly on your GitHub account. This is important as we'll use an internal dashboard with your avatars.

Homebrew

On Mac, you need to install Homebrew which is a Package Manager. It will be used as soon as we need to install some software. To do so, open your Terminal and run:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

This will ask for your confirmation (hit Enter) and your laptop session password.

If you already have Homebrew, it will tell you so, that's fine, go on.

Then install some useful software:

brew update

If you get a /usr/local must be writable error, just run this:

sudo chown -R $USER:admin /usr/local
brew update

Error message or not, proceed running the following in the terminal (you can copy / paste all the lines at once).

function install_or_upgrade { brew ls | grep $1 > /dev/null; if (($? == 0)); then brew upgrade $1; else brew install $1; fi }
install_or_upgrade "git"
install_or_upgrade "wget"
install_or_upgrade "imagemagick"
install_or_upgrade "jq"
install_or_upgrade "openssl"

Sublime Text 3 - Your text editor

A text editor is one of the most important tools of a developer. Go to this page and download Sublime Text 3 for OS X. Install it (double click the downloaded file and drag & drop the app into the Applications folder, don't skip this). If you had Sublime Text 2 installed before, please uninstall it (by dragging/dropping it to the Trash).

Sublime Text is free without any time limitation but a popup will appear every ten saves to remind you there is a license to buy. You can hit Esc when this happens, but feel free to buy Sublime Text if you really like this one (there are alternatives).

Again, make sure that Sublime Text is there, not in the disk image you downloaded. To make sure it's correct, once Sublime Text is installed, unmount the "Sublime Text 3" disk in the left panel of Finder. Finder will complain if something went wrong. Ask a teacher.

Oh-my-zsh - Fancy your Terminal

We will use the shell named zsh instead of bash, the default one.

curl -L http://install.ohmyz.sh | sh

Be careful, at the end of this script, it will prompt for your laptop password again. You have to write it correctly (you will not see it when you type) and hit Enter. You should get something like:

         __                                     __
  ____  / /_     ____ ___  __  __   ____  _____/ /_
 / __ \/ __ \   / __ `__ \/ / / /  /_  / / ___/ __ \
/ /_/ / / / /  / / / / / / /_/ /    / /_(__  ) / / /
\____/_/ /_/  /_/ /_/ /_/\__, /    /___/____/_/ /_/
                        /____/                       ....is now installed!

Now quit the Terminal (⌘ + Q), and restart it.

You should see something like this:

If not, stop right away and call a teacher.

On Mac, open Terminal > Preferences and set the "Pro" theme as default in Profiles (Réglages in French).

Quit and relaunch the Terminal. It should now have a nice black background, more easy on the eyes.

GitHub

We need to generate SSH keys which are going to be used by GitHub and Heroku to authenticate you. Think of it as a way to log in, but different from the well known username/password couple. If you already generated keys that you already use with other services, you can skip this step.

Open a terminal and type this, replacing the email with yours (the same one you used to create your GitHub account). It will prompt for information. Just press enter until it asks for a passphrase.

NB: when asked for a passphrase, put something you want (and that you'll remember), it's a password to protect your private key stored on your hard drive. You'll type, nothing will show up on the screen, that's normal. Just type the passphrase, and when you're done, press Enter.

mkdir -p ~/.ssh && ssh-keygen -t rsa -C "[email protected]"

Then you need to give your public key to GitHub. Run:

cat ~/.ssh/id_rsa.pub

It will prompt on the screen the content of the id_rsa.pub file. Copy that text, then go to github.com/settings/ssh. Click on Add SSH key, fill in the Title with your computer name, and paste the Key. Finish by clicking on the Add key green button.

To check that this step is completed, in the terminal run this. You will be prompted a warning, type yes then Enter.

ssh -T [email protected]

If you see something like this, you're done!

# Hi --------! You've successfully authenticated, but GitHub does not provide shell access

If it does not work, try running this before trying again the ssh -T command:

ssh-add ~/.ssh/id_rsa

Don't be in a rush, take time to read this article to get a better understanding of what those keys are used for.

Dotfiles (Standard configuration)

Hackers love to refine and polish their shell and tools. We'll start with a great default configuration provided by Le Wagon, stored on GitHub. As your configuration is personal, you need your own repository storing it, so you first need to fork it to your GitHub account.

➡️ Click here to fork the lewagon/dotfiles repository to your account. Forking means that it will create a new repo in your GitHub account, identical to the original one. You'll have a new repository on your GitHub account, your_github_username/dotfiles. We need to fork because each of you will need to put specific information (e.g. your name) in those files.

Open your terminal. Don't blindly copy paste this line, replace replace_this_with_your_github_username with your own github usernickname.

export GITHUB_USERNAME=replace_this_with_your_github_username

# Example:
#   export GITHUB_USERNAME=ssaunier

Now copy/paste this very long line in your terminal. Do not change this one.

mkdir -p ~/code/$GITHUB_USERNAME && cd $_ && git clone [email protected]:$GITHUB_USERNAME/dotfiles.git

Run the dotfiles installer.

cd ~/code/$GITHUB_USERNAME/dotfiles
zsh install.sh

Then run the git installer. It will prompt you for your name and your email.

Be careful, you need to put the same email as the one you sign up with on GitHub.

cd ~/code/$GITHUB_USERNAME/dotfiles
zsh git_setup.sh

Please now quit all your opened terminal windows.

Sublime Text auto-configuration

Open a new terminal and type this:

stt

It will open Sublime Text in the context of your current folder. That's how we'll use it.

Wait 1 minute for additional packages to be automatically installed (New tabs with text will automatically open, containing documentation for each new package installed).

To check if plugins are installed, open the Command Palette (⌘ + ⇧ + P on OSX, Ctrl + ⇧ + P on Linux), type in Packlist and then Enter, you should see a couple of packages installed (like Emmet).

If you don't, please install all of them manually. The list is referenced here.

Installing Ruby (with rbenv)

First we need to clean up any previous Ruby installation you might have:

Open a Terminal, and run the following. It will ask for your password again.

if [ -x "$(command -v rvm)" ]; then rvm implode && sudo rm -rf ~/.rvm; fi
sudo rm -rf $HOME/.rbenv /usr/local/rbenv /opt/rbenv /usr/local/opt/rbenv

Now let's get rbenv and ruby-build packages from Homebrew, they'll be useful.

brew uninstall --force rbenv ruby-build
unset RBENV_ROOT && source ~/.zshrc
brew install rbenv ruby-build && source ~/.zshrc

Now, you are ready to install the latest ruby version, and set it as the default version.

Run this command, it will take a while (5-10 minutes)

rbenv install 2.3.1

Once the ruby installtion is done, run this command tell the system to use the 2.3.1 version by default.

rbenv global 2.3.1

Then restart your Terminal (close it and reopen it).

ruby -v

You should see something starting with ruby 2.3.1p. If not, ask a teacher.

Installing some gems

gem install bundler rspec rubocop pry pry-byebug hub colored

Never install a gem with sudo gem install! Even if you stumble upon a Stackoverflow answer (or the Terminal) telling you to do so.

Postgresql

In a few weeks, we'll talk about SQL and Databases and you'll need something called Postgresql, an open-source robust and production-ready database. Let's install it now.

brew install postgresql
brew services start postgresql

Once you've done that, let's check if it worked:

psql -d postgres

If you enter a new prompt like this one, you're good!

psql (9.5.3)
Type "help" for help.

postgres=#

To quit it, type \q then Enter.

Keyboard

As you become a programer, you'll understand that leaving the keyboard takes a lot of time, so you'll want to minimize using the trackpad or the mouse. Here are a few tricks on OSX to help you do that:

Keyboard speed

Go to  > System Preferences > Keyboard. Set Key Repeat to the fastest position (to the right) and Delay Until Repeat to the shortest position (to the right).

Full Keyboard Access

Go to  > System Preferences > Keyboard. Click on the third tab (Shortcuts). At the bottom of the pane, click the radio button All controls. This way when you get a dialog with several options, you'll be able to type Enter to confirm, or Space to choose the cancel option. If you have more than two options, you can use tab to circle between them.

OSX For hackers

Read this script and cherry-pick some stuff you think will suit you. For instance, you can type in the terminal this one:

# Expanding the save panel by default
defaults write NSGlobalDomain NSNavPanelExpandedStateForSaveMode -bool true
defaults write NSGlobalDomain PMPrintingExpandedStateForPrint -bool true
defaults write NSGlobalDomain PMPrintingExpandedStateForPrint2 -bool true

# Disable system-wide resume
defaults write com.apple.systempreferences NSQuitAlwaysKeepsWindows -bool false

# etc..

Security

It is mandataory that you protect your session behind a password.If it is not already the case, go to  > System Preferences > Users & Groups, and change your account password. You should also go to  > System Preferences > Security > General. You should require a password 5 seconds after sleep or screen saver begins.

You can also go to  > System Preferences > Mission Control, and click on the Hot Corners button at the bottom left. Choose for the bottom right corner to start the screen saver. That way, when you leave your desk, you can quickly lock you screen by putting your mouse in the bottom right corner. 5 seconds after, your Macbook will be locked and will ask for a password to get back on the session.

Check-up

Let's check if you successfully installed everything.

Quit all opened Terminal, open a new one and run the following commands:

curl -Ls https://raw.githubusercontent.com/lewagon/setup/master/check.rb | ruby

It should tell you if your workstation is ready :) If not, ask a teacher.

Alumni

Register as a Wagon alumni by going to alumni.lewagon.org/onboarding. Select your batch, sign in with GitHub and enter all your information.

Your teacher will then validate that you are indeed part of the batch. You can ask him to do it as soon as you completed the registration form.

Once the teacher has approved your profile, go to your email inbox. You should have 2 emails:

  • One from Slack, inviting you to the Le Wagon Alumni slack community (where you'll chat with your buddies and all the previous alumni). Click on Join and fill the information.
  • One from GitHub, inviting you to lewagon team. Accept it otherwise you won't be able to access the lecture slides.

Slack

Download the Slack native app from the mac App Store, and sign in to lewagon-alumni organization.

Make sure you upload a picture there.

You can also sign in to Slack on your iPhone or Android device!

The idea is that you'll have Slack open all day, so that you can share useful links / ask for help / decide where to go to lunch / etc.

Enjoy your ride with Le Wagon :)
