  type
    Client = object
  
  proc connect*(client: var Client, server, username, password: cstring) {.exportc.} =
    discard
  
  Run

  when i call connect from js i have to do this:

  
  var c = newClient()
  connect(c, "server", "user", "pw");
  Run

  what must i do to call it like so:

  
  var c = newClient()
  c.connect("server", "user", "pw");
  Run

  Best I could come up with

  import jsffi
  
  type
    Client = object
      connect {.exportc.}: proc (server, username, password: cstring)
  
  proc connect*(client: var Client, server, username, password: cstring) =
    discard
  
  proc newClient*(): Client {.exportc.} =
    result = Client{}
    result.connect = proc (server, username, password: cstring) =
      connect(self, server, username, password)
  Run

  Are you sure it's worth it? I don't think JS output is supposed to be used in actual JS

  thank you Hlaaftana. I almost thought so. The reason i want to do this is i'm building a drop in replacement client for old js code. And others will use it where some have never written any nim, so the api should be as similar as possible (my goal of course is to remove all the js but step by step ;)).
