State of the WIDL

[Eric Kohl]

Hi all,

there is some good news to tell about WIDL. It is able to build the
header file, client stub file and server stub file for _very_ simple rpc
applications. I got a slightly modified version of the hello example
from MSDN working.

There are still a lot of features missing from WIDL but it is able to
create stubs for simple functions that don't take any arguments and
return no or basic type values. Returning pointers is not supported yet.
So, supported functions look like that:

	void My1stRpcFunc(void);
	int My2ndRpcFunc(void);
	unsingned long My3rdRpcFunc(void);

Another restriction is the handling of implicit binding handles. These
binding handles are usually declared in an ACF file. But since ACF files
are not supported yet the declaration must take place in the IDL file.
MIDL supports this as well if you use the '/app_config' option.

Explicit binding handles are not supported yet.

Finally, WIDL does not support MIDLs '/oldnames' option. This option is
used to enable the old naming conventions for interface handles. This is
a minor issue because the MSDN examples use the old naming conventions.


Next, I want to implement support for basic type function arguments.


The whole source code to WIDL is published under the LGPL so feel free
to contribute it to WINE.


Regards,
Eric

ros-diffs truncates messages so is there a SVN command I can use to generate a diff from
one rev
to another? I will merge and forward your WIDL changes to Winehq.

Thanks
Steven

Maybe you can find some usefull code here (though I doubt it): 
http://www.volny.cz/xnavara/idl/ (stubs.c particulary).

If you guys are going to be hacking on WIDL quite a bit then its going to be a pain for me
to keep
the changes in sync with Winehq. Can you maintain a changelog in the directory for the
changes for
each rev so I can know what to extract to try to merge to Winehq.

Thanks
Steven

Actually I'm not going to work on WIDL since I don't want to step on 
Eric's toes. If you're going to merge the changes back to Wine please 
don't do that for revision 13706.

Thanks,
Filip

I tried to remove all the ReactOS dependant changes. Anyone care to review the diff before
I send
it off?

Thanks
Steven

The patch to hash.c is part of Filips effort to eliminate warnings. The 
   patch looks good to me if you remove the hash.c part.

svn log svn://svn.reactos.com/trunk/reactos/tools/widl

will give you that information. You just need to remember the revision
of your last sync. You can do that using a regular file or a property.
