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

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

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

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.

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

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

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>
