gollum（githubのwikiエンジン）をサーバ （apache + passenger）で動かしたよメモ。

# A sample Gemfile
source "https://rubygems.org"

gem 'gollum'

# formats
gem 'redcarpet'
gem 'github-markdown'
gem 'wikicloth'

# capistranoとか
group :development do
  gem 'capistrano'
  gem 'capistrano-ext'
end

Gollum::Page.send :remove_const, :FORMAT_NAMES if defined? Gollum::Page::FORMAT_NAMES
Gollum::Page::FORMAT_NAMES = {
  :markdown  => "Markdown",
  :mediawiki => "MediaWiki"
}

Precious::App.set(:gollum_path, repos_path)
Precious::App.set(:default_markup, :markdown) 
Precious::App.set(:wiki_options,  {universal_toc: true})

run Precious::App
