GIT101 practice for fun :P

Let’s play with git practice step by step, shall we?

Here we go:

change into self_practice directory for class T1-2015

cd ~/workspace/davinci_coders_t1_2015/self_practice

make a new directory call practice

mkdir practice

get into the practice directory

cd practice/

In the practice directory, make a git_warmup directory

mkdir git_warmup

get into the git_warmup directory

cd git_warmup/

In the git_warmup directory:

Setup RVM

echo ‘2.1.5’ > .ruby-version

echo ‘git_warmup’ > .ruby-gemset

Get RVM to reload these setting:

cd .

rvm current

Setup Robocop

mine .

When RubyMine is open,

we use shortcut command + N to create a new file.

Type in <Gemfile> and click [OK] button. 

In Gemfile, we type in source ‘http://rubygems.org&#8217; in line 1, and gem ‘guard-rubocop’ in line 3.

Now we bundle the gems into our RubyMine files. 

Time to initialize guard with guard init, 

and you should see in your RubyMine have a Guardfile jump up in there. 

Now when your fire up guard, you will see that there are already 2 offenses for guard file alone. 

To fix this, we highlight the git_warmup directory, and going to create a new file command + N with a name <.rubocop.yml> in RubyMine. 

And put into these code into <.rubocop.yml> to exclude guardfile in rubocop: 

AllCops:
  Exclude:
    - 'Guardfile'

then the rubocop will tell you .

Setup Git

Command + T in iTerm to open a new tape, git init to create an empty repo locally, adding initial files, check status, commit initial setup files.  

If you hit (enter) after git commit, you are now into vim, just hit i turn into Insert mode and type in your commit message ‘Added initial setup files‘, hit [esc] button,  type :wq to save the change and quit vim

use git log -p to show any commit in this repo. 

hit q to exit vim.

In the git _warmup directory:

create a ruby program call greeting

You can either go to iTerm type in touch greeting.rb, or go into RubyMine highlight git_warmup directory, command + N, and type in greeting.rb, then click [OK] button. Has the program ask for your name, then print out “Nice to meet you, (your name here).”

	#!/usr/bin/env ruby
	print 'What is your name?'
	name = gets.chomp.capitalize
	puts "Nice to meet you, #{name}."

Now I want to check my git status. 

I’m feeling a little lazy today, let’s use gitx [enter]. Now we have a gitx box jump up, and I am using shortcut command + A to selected all files from the left box that I need to commit and draft them to the right box. 

put into commit message into the middle and click [commit] button, than close it on the left top [x] red button. 

When we type in git log, and we now have 2 commit repository. 

Now, let’s push a new repo on github.

Let’s go to github.com/new 

and we put into the Repository name as git_self_practice_for_fun_1, type in Description as just practice git101 for fun, then click [Create repository] button.  Make sure the [ssh] button is check on this new page, since we already have existing repository, we click the clipboard button on the …or push an existing repository from the command line, then go paste it onto iTerm using shortcut command + V [enter]. 

I’m not so sure if I get this down yet, how do I get more practice?

Let’s start the next one in the same directory practice
