Lab 8 - Prep - Creating Remote Repo and Cloning it, Warm Up Program(s)

Create Your Remote Repository

This will create a remote git repository on github.

Go to your account home (github.com/username).
Click on the Repositories tab.
Click the green New button on the right side.
Give your repository the name lab-08-if-while
The repository should be public (the default).
Click "Initialize this repository with a README".
Click Create Repository.
Refresh your main GitHub page and you should see the new repository.

Cloning your repository

This will clone the repository you just created on GitHub on your local machine.

open terminal
(if doesn’t already exist) create a folder that consists of your first initial and last name in your home directory

cd ~
mkdir myname

use pwd to verify that you’re in the correct folder
- you should be in ~/myname/
- if you’re not, cd into it
to prove that this is not yet a repository, list all files in your current directory

ls -al

it should contain only your previous labs
it should not contain any .git folders

Make sure again that you're in the correct directory! (/Users/student/myname or ~/myname)
Clone the GitHub repository you just created: lab-08-if-while

git clone https://github.com/your_username/lab-08-if-while.git

The output should be:

Cloning into 'lab-08-if-while'...
remote: Counting ojects: 3, done.
remote: Total 3 (delta 0), reused 0 (delta 0), pack-reused 0
Receiving objects: 100% (3/3), done.
Checking connectivity... done.

Check to make sure you've linked to your remote repository:
Change into your repository directory (lab-08-if-while).
Use the git remote command.

cd lab-08-if-while
git remote -v

You should see:

origin https://github.com/your_username/lab-08-if-while.git (fetch)
origin https://github.com/your_username/lab-08-if-while.git (push)

configure your name and email for your commits

# in the directory of your repository
git config user.name  "my first and last name"
git config user.email "my@email.address"

finally, use git config again to see if this worked:

git config -l

(use should see your name and email appear in the configuration)

Creating and Saving Changes Locally, Sending to Remote Repository

In this part of the lab, you will edit a text file in your local repository, and then you’ll send it to your remote repository.

open terminal
make sure you’re in your local repository folder for lab-08-if-while
- use pwd to do this
- you should be in ~/yourname/lab-08-if-while
- if you’re not in your lab folder, change your directory to it
- if this doesn’t exist yet… make sure you completed the beginning part of this lab
use git status to show that there aren’t any changes yet

git status

it should give the following output

On branch master
Your branch is up-to-date with 'origin/master'.

nothing to commit, working directory clean

You will have a file called README.md in your lab-08 directory. Open it using SublimeText (see below…)
Go to Applications → SublimeText (or use Command+Spacebar to activate spotlight search, then start typing Sublime)
Once SublimeText is open, open the README.md file by going to File → Open
Add the following to your file: "This is lab 08...more JavaScript conditionals."
Save your file by going to File → Save (or command+s).
Switch back to terminal
Use git status to show that you’ve made changes

git status

it should give the following output; notice that it contains README.md

On branch master
Your branch is up-to-date with 'origin/master'.

Changes not staged for commit:
  (use "git add ..." to update what will be committed)
  (use "git checkout -- ..." to discard changes in the working directory)

      modified:    README.md
no changes added to commit (use "git add" and/or "git commit -a")

if we want to save this file in the repository, we have stage it (that is, mark it as something that we’re ready to save / commit)

git add --all

to check that you’ve staged your commit, use git status again

git status

it should output the following text (note that README.markdown moved from untracked to Changes to be committed)

On branch master
Your branch is up-to-date with 'origin/master'.

Changes to be committed:
  (use "git reset HEAD ..." to unstage)

      modified:    README.md

now we’re ready to commit (that is, save the file to the local repository); everything after the -m is the message that will be associated with the changes that you’ve made

git commit -m "edited the README file"

the output of the command should be:

[master 5b24d27] edited the readme file
 ...etc

check the status again

git status

notice that there is nothing staged and no more changes!

# On branch master
nothing to commit, working directory clean

to show the changes that you’ve saved so far, use git log

git log --color

it should show you the following…

commit 5b24d2777a602908978916ca8fe9c8dd2ed6036b
Author: bree <bzuckerman@citytech.cuny.edu>
Date:   Wed Mar 5 11:45:21 2015 -0500

    edited the README file

you can share your changes / send them to a remote repository by using git push

git push origin master

it should result in:

Counting objects: 3, done.
Writing objects: 100% (3/3), 242 bytes | 0 bytes/s, done.
Total 3 (delta 0), reused 0 (delta 0)
To https://github.com/bzuckerman/lab-08-if-while.git
 * [new branch]      master -> master

go back to GitHub and look in your repository. You should see the changes in the Readme file.

Instructions for Warm-Up Programs

Note that ALL OF THESE FILES MUST BE SAVED IN THE LOCAL REPOSITORY THAT YOU CREATED FOR THIS LAB.

add dice

Write a program that asks for the result of two dice rolls. Add the results of both rolls and print out the sum.

using SublimeText, create a new file called adddice.html in your repository directory: ~/Desktop/llorenzo/lab-08-if-while/
setup an html file, and add script tags… start writing your JavaScript between the script tags
the program should ask for the result of the first die roll: “Give me a number for the first roll (1-6)”
the program should ask for the result of the second die roll: “Give me a number for the second roll (1-6)”
use the parseInt function to convert both inputs from a string to a number (for example: num1 = parseInt(roll1, 10))
then… add both numbers together and print out the output to the JavaScript console
example interaction is below (everything after the greater than sign (> is user input using the prompt function):

(prompt) Give me a number for the first roll (1-6)
> 1
(prompt) Give me a number for the second roll (1-6)
> 5
The sum of both rolls is 6.

save your file in SublimeText
use git status, add, commit, and push to save your file in version control and submit it

fortune

Write a program that asks for number. The program will translate that number into a fortune.

using SublimeText, create a new file called fortune.html in your repository directory: ~/Desktop/llorenzo/lab-08-if-while/
setup an html file, and add script tags… start writing your JavaScript between the script tags
the program should ask for a number: “Give me a number between 1 and 3, and I’ll predict your future…”
use the parseInt function to convert the input from a string to a number (for example: num = parseInt(answer, 10))
compare the resulting number to a number corresponding to a fortune of your own creation, e.g.:
- 1 - you will type in the word “git” many times
- 2 - you will be hungry by the end of class
- 3 - etc…
print out the corresponding fortune to the JavaScript console…
if the number doesn’t correspond to a fortune, print out: “you don't follow directions very well“
example interaction is below (everything after the greater than sign (> is user input using the prompt function):

# Run 1
(prompt) Give me a number between 1 and 3, and I'll predict your future...
> 2
you will be hungry by the end of class

# Run 2
(prompt) Give me a number between 1 and 3, and I'll predict your future...
> 24
you don't follow directions very well

save your file in SublimeText
use git status, add, commit, and push to save your file in version control and submit it
