Vim RuboCop

The Vim RuboCop plugin runs RuboCop and displays the results in Vim.

Requirements

Please note that the current version of the Vim RuboCop plugin requires RuboCop 0.12.0 or later.

Installation

Obtain a copy of this plugin and place rubocop.vim in your Vim plugin directory.

Usage

You can use the :RuboCop command to run RuboCop and display the results.

You can also use the :RuboCop command together with options. For example, :RuboCop -l, :RuboCop -a and so on.

Configuration File

To run with the specified configuration file, add the following line to your .vimrc file:

let g:vimrubocop_config = '/path/to/rubocop.yml'

Keyboard Shortcuts

Credit for Shortcuts: Ack.vim

In the quickfix window, you can use:

o    to open (same as enter)
go   to preview file (open but maintain focus on ack.vim results)
t    to open in new tab
T    to open in new tab silently
h    to open in horizontal split
H    to open in horizontal split silently
v    to open in vertical split
gv   to open in vertical split silently
q    to close the quickfix window

Additionally, the plugin registers <Leader>ru in normal mode for triggering it easily. You can disable these default mappings by setting g:vimrubocop_keymap in your .vimrc file, and then remap them differently.

For instance, to trigger RuboCop by pressing <Leader>r you can put the following in your .vimrc:

let g:vimrubocop_keymap = 0
nmap <Leader>r :RuboCop<CR>
