class Roda
module RodaPlugins
# The not_found plugin adds a +not_found+ class method which sets
# a block that is called whenever a 404 response with an empty body
# would be returned. The usual use case for this is the desire for
# nice error pages if the page is not found.
#
# You can provide the block with the plugin call:
#
# plugin :not_found do
# "Where did it go?"
# end
#
# Or later via a separate call to +not_found+:
#
# plugin :not_found
#
# not_found do
# "Where did it go?"
# end
#
# Before not_found is called, any existing headers on the response
# will be cleared. So if you want to be sure the headers are set
# even in a not_found block, you need to reset them in the
# not_found block.
#
# This plugin is now a wrapper around the +status_handler+ plugin and
# still exists mainly for backward compatibility.

# Require the status_handler plugin
def self.load_dependencies(app)
app.plugin :status_handler
end
# If a block is given, install the block as the not_found handler.

app.not_found(&block)
end
end
