module Controller
##
# Controller that can be used to render a block of markup based on the POST
# data. This controller is useful for generating previews when using the
# text editor for example.
#
# In order to render a preview you'll have to send a POST request with the
# following data in it:
#
# * engine: The markup engine to use (Markdown, Textile, etc).
# * markup: The markup to convert to HTML.
#
# An example of such a request would look like the following:
#
# POST /admin/preview
# engine: "markdown"
# markup: "Hello **world**!"
#
# The return data is an HTTP status code and the HTML as the body. The HTTP
# status code will be 200 whenever the data was converted and or 400 in case
# of an error (e.g. an incorrect markup engine was specified).
#
# @since 0.2.6
#
class Preview < Zen::Controller::AdminController
map '/admin/preview'
##
# Converts the markup set in the POST data and returns the HTML.
#
# @since 0.2.6
#
def index
if !request.params['engine'] or !request.params['markup']
respond(lang('zen_general.errors.invalid_request'), 400)
end
begin
respond(
Zen::Markup.convert(
request.params['engine'],
request.params['markup']
),
200
)
rescue
respond(lang('zen_general.errors.invalid_request'), 400)
end
