Durden can generate a not too bad WSDL from specially cooked erlang modules. It also can handle SOAP/1.2-bound requests.

Soap transports:

• HTTP-POST
• SOAP/1.1
• HTTP-GET

Support of indirect reference loops in the types declarations (currently parse transformation hangs when analysing a types like "A references B references A again")

Human readable documentation page (alike to that one generated when you visit .Net's ASMX page with no parameters)

Durden analyses the source of the module supposed to become a Web-service via parse-transform.

The specs of the functions enlisted in 'soap_actions' attribute are analysed.

All the mentioned types are gathered recursively.

The type info is then used as the return value of a generated function Module:'#durden.get_wsd#'/0.

Besides the latter, 'cowboy_http_handler' behaviour is implemented: init/3 callback just asks Cowboy to upgrade the protocol into 'durden_cowboy_http_soap'.

(https://github.com/RGafiyatullin/durden_examples)

The following module:

-module(soap_test_service).
-compile({parse_transform, durden_pt}).

-include_lib("durden/include/predefined_types.hrl").

-soap_target_ns("http://rgafiyatullin.github.com/test-service").
-soap_service_name("TestService").

-soap_actions(['GetUserByID'/1]).

-type phone_numbers() :: [ string() ].

-record('User', {
	'ID' :: uuid(),
	'Name' :: string(),
	'YearOfBirth' :: integer(),
	'Phones' :: phone_numbers()
	}).

-spec 'GetUserByID'( ID :: uuid() ) -> #'User'{}.
'GetUserByID'( ID ) ->
	#'User'{
		'ID' = ID,
		'Name' = "Test User",
		'YearOfBirth' = 1988,
		'Phones' = ["+375005550000", "+375115550000"]
	}.
