Sinatra::Capture

Extension that enables blocks inside other extensions. It currently works for erb, slim and haml. Enables mixing of different template languages.

Example:

   # in hello_world.erb

   Say
   <% a = capture do %>World<% end %>
   Hello <%= a %>!

   # in hello_world.slim

   | Say
   - a = capture do
     | World
   |  Hello #{a}!

   # in hello_world.haml

   Say
   - a = capture do
     World
     Hello #{a.strip}!

You can also use nested blocks.

Example

    # in hello_world.erb

    Say
    <% a = capture do %>
      <% b = capture do %>World<% end %>
        <%= b %>!
    <% end %>
    Hello <%= a.strip %>

The main advantage of capture is mixing of different template engines.

Example

   # in mix_me_up.slim

   - two = capture do
     - erb "<%= 1 + 1 %>"
   | 1 + 1 = #{two}

Usage

Classic Application

In a classic application simply require the helpers, and start using them:

    require "sinatra"
    require "sinatra/capture"

    # The rest of your classic application code goes here...

Modular Application

In a modular application you need to require the helpers, and then tell the application you will use them:

    require "sinatra/base"
    require "sinatra/capture"

    class MyApp < Sinatra::Base
      helpers Sinatra::Capture

      # The rest of your modular application code goes here...
    end
