Up and Running with iTerm, Tmux, Vim, and vim-rails

Make it a point to be able to use the keyboard as much as you can. In OS X the spotlight is great for this. By default the spotlight hotkey is Cmd+Space. Make it a point to try and always use iTerm in fullscreen. Remember that your tmux prefix is set to Ctrl+z

• Open iTerm with spotlight with Cmd+Space search iTerm and open with Enter
• Fullscreen iTerm with Cmd+Enter
• Pop out of iTerm with the hotkey you added Ctrl+Enter
• Pop back into iTerm with Ctrl+Enter again
• Nagivate to your intended project directory
• Check for running tmux sessions with tmux ls (Failed to connect to server just means no tmux sessions yet)
• Start a named tmux session with tmux new -s myprojectname
• Detach from that session with prefix d
• List tmux sessions again with tmux ls
• Connect to your detatched, running session with tmux att -t myprojectname
• Split your screen vertically with prefix % or use the alias prefix |
• Move the split border so that the pane on the right occupies about 80% screen real estate with prefix H or prefix L
• Move between the vertical splits with prefix h or prefix l
• Open vim in the large pane. In your project directory run vim .
• Keep the smaller pane of this window free for test output and running rake tasks or git commands
• Open a new window with prefix c
• Split this window vertically with prefix % or prefix |
• In the pane on the left run rails c and in the pane on the right run rails s or tail -f log/development.log when using POW
• Go forward and backward between your two windows with prefix n (next) and prefix p (previous), with only two windows it doesn't matter too much which.
• Learn the vim-rails commands for navigation https://github.com/tpope/vim-rails
• Learn how :Econtroller, :Emodel, :Eview work to find files. Note that you can type :Eco and tab for example.
• Create a new model with :Emodel my_new_model!
• Create a new controller with :Econtroller my_new_controller!
• Create a new view with :Eview path/to/my_new_view.html.erb!
• Jump from a controller action to its view template with :Eview from inside the controller action
• Jump from a view template to its controller with :Econtroller
• Jump from a model or controller to its test with :A
• Open an alternate file in a new vertical split with :AV
• Open an alternate file in a new horizontal split with :AS
• Open a model in a new tab with :Tmodel and the model name
• Nagivate splits in vim with the prefix Ctrl+w and then one of h,j,k,l
• Nagivate tabs in vim with gt and gT
• Open a controller in a horizonal split with :Scontroller and the controller name
• Remember you can always open or create new files with the standard vim command :e followed by a space and a filename with or without a relative path.
