Can't capture blocks or use instance variables

[activestylus]

I'm rolling my own static site generator with Slim and am struggling to pass content to the layout from the page using instance variables or content_for.

Lifted some code from Sinatra but no luck so far

def render_slim
  data = {"title" => "Hello"}
  layout  = Slim::Template.new("layout.slim")
  page = Slim::Template.new("page.slim").render(Object.new, data)
  layout.render(Object.new, data) { content } 
end

# From Sinatra
def content_for(key, &block)
  content_blocks[key.to_sym] << block.call
  return ""
end

def content_for?(key)
  content_blocks[key.to_sym].any?
end

def yield_content(key, *args)
  content_blocks[key.to_sym].join
end

def content_blocks
  @content_blocks ||= Hash.new {|h,k| h[k] = [] }
end

/ page.slim
- @title = 'My Title'
h1=data['title']
= content_for :css do
  | body {color:red}

/ layout.slim
html
  head
    title= @title
    style
      == yield_content :css

Not throwing any errors, I simply end up with empty title and style tags in my layout.

What am I missing?

Hi, I suspect that the captured content doesn't land at the "right" place. Did you check that the current object (from where the instance variables are taken) is the same in both the layout and the page?
