My first Syro app: a wiki!

app.rb

App = Syro.new do
  on 'wiki' do
    if root?
      run PageRouter, page: 'wiki'
    else
      run UtilityRouter
    end
  end

  on :page do
    run PageRouter, inbox
  end

  res.redirect '/wiki', 301
end

page.rb

PageRouter = Syro.new(WikiPage) do

  on (req.path.end_with? '/') do
    res.redirect req.path.chop, 301
  end

  on page_exists? do
    get do
      if req.params.key? 'edit'
        render :edit, content: fetch_page_markdown
      else
        render_page
      end
    end

    delete do
      delete_page
      res.redirect '/wiki'
    end

    head {} # 200 status for client-side file detection

    patch do
      update_page
      store_uploads
      reload_page
    end
  end

  get do
    res.status = 404
    render :new
  end

  post do
    create_page
    store_uploads
    reload_page
  end
end

utility.rb

UtilityRouter = Syro.new(WikiPage) do
  on :utility do
    if root? and req.get? and utility_exists?
      res.status = 200

      if 'search' == inbox[:utility]
        render('wiki/search', query: req.params['query'])
      else
        render('wiki/%s' % inbox[:utility])
      end
    else
      res.text 'This utility page does not exist.'
    end
  end
end
