vim-ruby-doc is a little plugin that helps you to look up documentation using the following resources:

• Ruby

  rubydoc.info

• RSpec

  relishapp.com

• Rails

  http://api.rubyonrails.org

If you want something similar for jQuery API documentation see vim-jquery-doc.

I strongly recommend installing pathogen.vim.

cd ~/.vim/bundle
git clone git://github.com/lucapette/vim-ruby-doc.git

Or you can unzip it in your ~/.vim directory.

In Normal mode, when your cursor is on something you would look up type:

• RB for Ruby
• RS for RSpec
• RR for Rails

and the plugin will open a new tab in your browser (or a new instance of the browser) to the related docs. See the following section for changing mappings.

Furthermore, the plugin defines the following commands for searching on the command-line arbitrary stuff:

• :RubyDoc
• :RspecDoc
• :RailsDoc

By default, the plugin uses the xdg-open command to look up the docs but you can easily change the command. For example, if you are on OSX you would like to change it:

let g:ruby_doc_command='open'

Furthermore you can choose your own mapping in the following way:

let g:ruby_doc_ruby_mapping='KK'

There are g:ruby_doc_rspec_mapping and g:ruby_doc_rails_mapping variables too.

You can change where the plugin should search very easily:

let g:ruby_doc_ruby_host='http://apidock.com/ruby/'

• imajes

  Include /doc/tags in .gitignore.

• coffeejunk

  Move away from apidock.

• sumskyi

  Add configurable search host.
