Plugin is from https://github.com/walm/jshint.vim
- 2 or 4 spaces instead of tabs (2 is default; Ctrl-f sets it to four and Ctrl-t back to 2)
- Auto-indentation can be toggled on and off with Ctrl-i
- Line numbers that can be toggled on and off with Ctrl-n
- jshint on save
I find the toggling useful when copying and pasting using the mouse (numbers off to copy, smartindent off to paste).
Copy the entire contents of the repo into /etc/vim.
