Construct a link to url_fragment, which should be given relative to the base of this Sinatra app. The mode should be either :path_only, which will generate an absolute path within the current domain (the default), or :full, which will include the site name and port number. (The latter is typically necessary for links in RSS feeds.) Example usage:
url_for "/" # Returns "/myapp/" url_for "/foo" # Returns "/myapp/foo" url_for "/foo", :full # Returns "http://example.com/myapp/foo"
# File lib/sinatra/url_for.rb, line 16 def url_for url_fragment, mode=:path_only case mode when :path_only base = request.script_name when :full scheme = request.scheme if (scheme == 'http' && request.port == 80 || scheme == 'https' && request.port == 443) port = "" else port = ":#{request.port}" end base = "#{scheme}://#{request.host}#{port}#{request.script_name}" else raise TypeError, "Unknown url_for mode #{mode}" end "#{base}#{url_fragment}" end
