Vim Config

This is a basic Vim setup that can be used to get you started using the tool.

Instructions

1. Download your color scheme. tomorrow-theme (moved here) is a great collection of color schemes. The Tomorrow Night Eighties is my personal favorite.

2. Setup your .vimrc. Here is an example .vimrc that sets up basic ruby plugins, line indents, etc.

3. Restart any open Vim instances for the changes to take affect.

Plugins

Plugins allow you to add extra functionality to Vim. You typically will use a plugin manager to add these add / remove these plugins. Most of these allow you to clone the plugin into your .vim directory. Here are a few popular plugin managers and plugins:

• Pathogen - very popular plugin manager
• nerdcommenter - plugin for commenting out code. I love this plugin... so smooth. <leader> cc <leader> cu
• nerdtree - visual file tree for your project <ctrl> n
• supertab - tab autocompletion while in insert mode
• vim-endwise - automatically adds end in Ruby
• vim-rails - shortcuts for rails projects :Emodel user
• vim-sensible - the perfect default config for vim
• vim-test - keyboard shortcuts for running tests
• vim-textobj-rubyblock - ability to select an entire ruby block
• fzf.vim - fulltext search

TMUX Integration

If you like, you can run your tests in a separate TMUX pane. When you initially run your tests, you will be prompted to choose what pane you would like to see the test results in.

By pressing prefix q (with prefix being your TMUX leader key), you can see the numbers on each pane.
