# = Action View Context
#
# Action View contexts are supplied to Action Controller to render a template.
# The default Action View context is ActionView::Base.
#
# In order to work with ActionController, a Context must just include this module.
# The initialization of the variables used by the context (@output_buffer, @view_flow,
# and @virtual_path) is responsibility of the object that includes this module
# (although you can call _prepare_context defined below).
module Context
include CompiledTemplates
attr_accessor :output_buffer, :view_flow
# Prepares the context by setting the appropriate instance variables.
# :api: plugin
def _prepare_context
@view_flow = OutputFlow.new
@output_buffer = nil
@virtual_path = nil
end
# Encapsulates the interaction with the view flow so it
# returns the correct buffer on +yield+. This is usually
# overwriten by helpers to add more behavior.
# :api: plugin

name ||= :layout
view_flow.get(name).html_safe
