ContentFor

Small extension for the Sinatra web framework that allows you to use the following helpers in your views:

<% content_for :some_key do %>
  <chunk of="html">...</chunk>
<% end %>

<% yield_content :some_key %>

This allows you to capture blocks inside views to be rendered later in this request. For example, to populate different parts of your layout from your view.

Usage

If you're writing “classic” style apps, then requring sinatra/content_for should be enough. If you're writing “classy” apps, then you also need to call helpers Sinatra::ContentFor in your app definition.

And how is this useful?

For example, some of your views might need a few javascript tags and stylesheets, but you don't want to force this files in all your pages. Then you can put <% yield_content :scripts_and_styles %> on your layout, inside the <head> tag, and each view can call content_for setting the appropriate set of tags that should be added to the layout.

Warning

This only works with ERB as a rendering mechanism. I haven't figured how to make it work with Haml. If you find a way, contact me and I'll include it.
