$ git clone https://github.com/arr2036/omnigollum.git

$ cp config.rb.example config.rb

Customize config.rb to use your preferred omniauth strategy.

Execute via Gollum

$ gollum --config config.rb

$ gem install omnigollum

Omnigollum executes an OmniAuth::Builder proc/block to figure out which providers you've configured, then passes it on to omniauth to create the actual omniauth configuration.

To configure both omniauth and omnigollum you should add the following to your config.ru file.

require 'omnigollum'

require 'omniauth/strategies/twitter'
require 'omniauth/strategies/open_id'

options = {
  # OmniAuth::Builder block is passed as a proc
  :providers => Proc.new do
    provider :twitter, 'CONSUMER_KEY', 'CONSUMER_SECRET'
    provider :open_id, OpenID::Store::Filesystem.new('/tmp')
  end,
  :dummy_auth => false
}

# :omnigollum options *must* be set before the Omnigollum extension is registered
Precious::App.set(:omnigollum, options)

By default, any authenticated user will be able to access the protected routes. Restrict this by setting the authorized_users option.

authorized_users accepts an array of emails. Users must authenticate with one of these authorized emails in order to be allowed access.

options[:authorized_users] = ["[email protected]", "[email protected]", "[email protected]"]

Instead of setting these directly, you can use an env var, maybe like this:

# in .env, or other
# [email protected],[email protected],[email protected]

options[:authorized_users] = ENV["OMNIGOLLUM_AUTHORIZED_USERS"].split(",")

Precious::App.register Omnigollum::Sinatra

You can (optionally) apply the patches here, to get a neat little auth status widget in the top right corner of the page https://github.com/arr2036/gollum/commit/dd1fdad59d9f12bfe637704c0101af96aaa1a7e4
