You can also run gollum with any rack-compatible server by placing this config.ru file inside your wiki repository. This allows you to utilize any Rack middleware like Rack::Auth, OmniAuth, etc.

#!/usr/bin/env ruby
require 'rubygems'
require 'gollum/app'

gollum_path = File.expand_path(File.dirname(__FILE__)) # CHANGE THIS TO POINT TO YOUR OWN WIKI REPO
wiki_options = {:universal_toc => false}
Precious::App.set(:gollum_path, gollum_path)
Precious::App.set(:default_markup, :markdown) # set your favorite markup language
Precious::App.set(:wiki_options, wiki_options)
run Precious::App

The options hash

The options available for the :wiki_options hash mostly correspond to the arguments used when running gollum from the command line, but there are some small exceptions. See here for a list of available options.

The --base-path option

The --base-path option has no equivalent in the options hash. This is because base path is implemented as a piece of middleware. If you want to use base_path with your config.ru setup, use the Precious::MapGollum class instead of Precious::App as your app:

# config.ru
require 'rubygems'
require 'gollum/app'

sub_dir = 'my-www-sub-folder'

Precious::App.set :wiki_options, { base_path: sub_dir } # this does nothing but helps remembering this setting

run Precious::MapGollum.new(sub_dir)

Setting author info and commit notes using middleware

You can customize the author info (name and email) used to save commits, as well as adding git notes to commits, inside a Rack middleware. To do this, your middleware needs to modify the session Hash inside the Rack request as illustrated below:

session['gollum.author'] = {
  :name => "Bilbo",
  :email => "[email protected]",
}
session['gollum.note'] = "My commit note"

Note that authentication solutions like OmniGollum and gollum-auth (see here) offer support for setting author info out of the box.

You could also use the Sinatra before method inside a config.ru or config.rb to set author info and commit notes:

class Precious::App
    before do
        session['gollum.author'] = {
            :name => "Bilbo",
            :email => "[email protected]",
        }
        session['gollum.note'] = "My commit note"
    end
end
