Set up your computer

Here are the account, text editor and shell you will use for the class.

Set up an environment for your tools

  • Using spotlight (command + space), open iTerm2.
  • Install homebrew:

    • Paste the following into your iTerm window. Hit enter:

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

      (A prompt will ask you to install Xcode. Say yes.)

    • After that, make sure brew is configured correctly entering:

      brew doctor

      You might get some scary-looking messages, don't fret, we'll pause and take a look!

Install git

brew install git

Configure git

git config --global color.ui true
git config --global user.name "YOUR NAME"
git config --global user.email "YOUR@EMAIL.com"

Then:

  1. Follow the instructions here to cache GitHub password. (The password it asks for will be your system password.)
  2. Configure your SSH keys based on the tutorials (follow in order).

Set up habits

  • Preferences > Keyboard.

    • fastest key repeat
    • shortest delay

  • Create an alias so you can open files in Sublime Text from the Command Line.

ln -s '/Applications/Sublime Text 2.app/Contents/SharedSupport/bin/subl' /usr/local/bin/subl

Command Line Interface

Q: How did we install and configure all the stuff above?

A: Command Line.

In fact, before there was click/double click/drag, there was the Command Line. Recommended reading.

  • cd -- navigate to directory
  • ls -- list all the content in the current directory
  • mkdir -- make a directory within the current directory
  • touch -- create a file within the current directory
  • mv -- rename/move
  • rm -- remove a file or directory within the current directory

Your new fam (in CLI):

  • . -- you
  • .. -- mom
  • ../.. -- granny

The many faces of cd:

  • cd Docouments -- go to Documents
  • cd . -- stay put
  • cd .. -- go one level back (to mom's!)
  • cd ../.. -- go two levels back
  • cd -- go back to the root directory

Exercise

Consult the frequently used commands listed above.

  1. Navigate to Desktop.
  2. Create a new directory called miceless.
  3. Navigate to miceless.
  4. Create a new file called name.txt.
  5. Open name.txt with subl.
    • What happens when you do subl .?
  6. Add your name in the text file, save it.
  7. Rename name.txt as myname.txt
  8. Remove the text file.
  9. Navigate back to Desktop.
  10. Remove the directory miceless.
    • Use rmdir or rm -r.

A little git primer

What is it?

man git

Why are we using it?

In short, you are using git to:

  1. to track your changes

You are using GitHub as a service to:

  1. see these changes in a UI, and
  2. collaborate with other people.

Git of the week

Put a git on it.

In your website directory:

  • git init
  • ls -a -- What do you see?

Look around:

  • git status
