[curl-email-news] Re: curl-email: illegal forward reference in AsyncClientConnection.curl

[David G. <da...@cu...>]

Actually this is more of a circular reference problem than a forward
reference problem (regardless of what the error message says).

Try this code:


{let public constant MyClassCallback:Type =
    {proc-type {class:MyClass}:void}}


{define-class public MyClass
  field public cb:MyClassCallback

  {constructor public {default}
    set self.cb = {proc {c:MyClass}:void}
  }
}

It gives you the same error. Notice, if you remove the cb field from
MyClass the forward reference works fine. Also, you can keep the cb field
if you declare MyClassCallback -after- you declare MyClass.

I don't know why this works in some code and not in other code. I also
don't know why moving the callback after MyClass fixed the problem.

For the email client, I would suggest moving the callback declarations to
the end of the file an continue from there.

If I find any info about what's going on I'll post it.

Hi,

I tried to write a test for the SMTP package. I get the following error:

curl-email/curl-email/AsyncClientConnection.curl:26
Illegal forward reference in definition of AsyncClientConnectCallback

curl-email/curl-email/AsyncClientConnection.curl:34
Illegal forward reference in definition of AsyncClientConnectCallback

I don't understand that because it works in the email-client. I tried the
following and the same errors occured.

{curl 1.6 applet}

{import * from CURL.IO.SOCKET}
{include "AsyncClientConnection.curl"}
Some Text!



Do you have a clou what's wrong?
