Dotfiles

Github Setup

Create your ssh key to talk to github without username and password prompts.

  ssh-keygen -t rsa -b 4096 -C smith11235@gmail.com
  # > hit enter to use default: ~/.ssh/id_rsa
  # > hit enter to have no password

Configure your username and email settings 1 time

  git config --global user.name "Michael Smith"
  git config --global user.email smith11235@gmail.com

Go to github.com/settings/ssh to add your new ssh key to github.

From your server copy the contents of ~/.ssh/id_rsa.pub and add it to the github key.

Name it after your development environment.

Dotfiles Setup

Get this repo, and load it to your environment so all the helper scripts and commands are available.

Specifically ./profile.

  git clone git@github.com:smith11235/dotfiles.git
  cd dotfiles
  ruby dotfiles.rb

If ruby isnt installed, run sudo apt-get install ruby -y

Tmux

Use it. Love it.

Start A New Project Session

  tn project_name # new session: tmux new -s

Use Multiple Tabs

  ctrl-b c        # new tab
  ctrl-b n        # next tab
  ctrl-b l        # last tab

  # close a tab by 'exit'ing
  exit

Detach From Your Session

Either detach and exit, or just close your terminal window.

Detaching lets you return to your work later as if you never left.

  ctrl-b d        # detatch from session

Reattach To Your Session

  ssh user@my-server.com

  tls              # list project sessions by name: tmux ls
  > project_name
  > my-project
  > my-other-project

  tat project_name # attach to a session by name: tmux attach -t

Ruby

For any ruby/rails project, from your root directory make and use a project specific rvm/ruby install.

First Time Install

  cd my_project
  tn my_project    # new tmux session in this directory
  which rvm # ensure none is found
  which rails # ensure none is found
  build_rvm        # build rvm, install Gemfile

Returning to Work

  tat my_project   # attach to tmux session where you left off
  ctrl-b c         # new tab for work
  load_rvm         # load rvm environment
  rails server

Working with Git

Starting work for a new ticket/task, start a branch off master

  git checkout master
  gpull                               # pull current branch from github

  git checkout -b my-new-branch
    
  # edit files for your work
  ...

  gs                                  # git status
  gd                                  # git diff

  gc -am "got some feature to work"   # git commit

  gp                                  # push current branch to github

VIM - Mans Best Friend

To edit code on a server, without a mouse

  vim some/file.txt

Command Mode

By default you are in command mode and cannot edit the file.

In general most 'commands' will start by typeing :.

Editing

  i            # enter insert mode before the cursor

  ... edit text with your keyboard...

  esc          # exit insert mode, back to command mode

Other ways to enter insert mode:

  shift+i    # start editing at beginning of line

  a  # start editing after the cursor
  shift+a    # start editing at end of line

  o          # start editing a new line below the cursor
  shift+o    # start editing a new line above the cursor

Basic Movement

  j  # down
  k  # up
  h  # left 
  l  # right

  w  # word forward
  b  # word back

Working with Files in Tabs

All of these are from command mode

  # open a new file in a tab
  :tabe path/to/file.txt

  # save your edits 
  :w

  # close a file/tab
  :q

  # switch tabs
  ctrl+h     # tab left (h is the move left key!)
  ctrl+l     # tab right (l is the move right key!)

Find Replace

  :%s/some-text-to-find/text-to-replace-it-with/gc

This is based on regex's, they are worth learning.

Selecting Text - Copy/Cut/Paste

  v          # start a basic selection, use movement keys to select text
  
  shift+v    # start a full line selection, use up/down movement keys to select more lines

  ctrl+shift+v # start a column/section selection, movement keys to select text

  # when text is selected, you can 

  # copy it (yank it)
  y 

  # or cut it (delete it)
  d

  # and then paste it elsewhere
  p

Or if you just want to find something.

  # type in a forward slash and then the text to find
  /some-pattern-to-find  <enter>  # takes you to first match
  n                               # to go to next match

Other Useful Tidbits

  :set number         # show line numbers
  :set nonumber       # hide line numbers (if you want to copy paste)

  # copy paste form outside vim to inside vim
  :set paste          # to paste from your computer to vim
  i                   # enter insert mode
  command-v           # normal mac-osx paste command
  :set nopaste        # go back to normal editing mode
