class Roda
module RodaPlugins
# The default_headers plugin accepts a hash of headers,
# and overrides the default_headers method in the
# response class to be a copy of the headers.
#
# Note that when using this module, you should not
# attempt to mutate of the values set in the default
# headers hash.
#
# Example:
#
# plugin :default_headers, 'Content-Type'=>'text/csv'
#
# You can also modify the default headers later:
#
# plugin :default_headers
# default_headers['Foo'] = 'bar'
# default_headers.merge!('Bar'=>'baz')
module DefaultHeaders
# Merge the given headers into the existing default headers, if any.
def self.configure(app, headers={})
app.instance_eval do
@default_headers ||= {}
@default_headers.merge!(headers)
end
end

# The default response headers to use for the current class.
attr_reader :default_headers
# Copy the default headers into the subclass when inheriting.

# Get the default headers from the related roda class.
