[Dojo-interest] Re: Designing for extensibility: naming widgets

[Shane O'Sullivan]

Yes, I understand how this makes the dojo.require("myNS.myWidget")
work, but does it enable me to include widgets as follows:

<dojo:Button ..../>
<myNS:myWidget .... />

I was under the impression that the dojo namespace was still the only
supported namespace when defining tags.

I think it would be very useful to extend the namespacing model to
cover both the dojo.require() statements and the tag-based
definitions.  What would be very useful would be to make it possible
to remove any dojo.require statements from being required, and instead
have the namespace be able to handle requests for the instantiation of
a widget.  For example, instead of simply having

<script>
    dojo.require("myNS.myWidget");
</script>
....
<myNS:myWidget .../>

We could simply have:
    <myNS:myWidget .../>
and the dojo.defineNamespace method could take a fourth parameter,
which is a package resolver.  For example:

function resolver(name){
    if(name == "myWidget") dojo.require("myNS.myWidget");
    else if(name == "myOtherWidget") dojo.require("myNS.myOtherWidget");
}

dojo.defineNamespace("myNS", "../myNS/", "myNS", resolver);

This change would make it possible to have a Javascript-less web page
using just a Dojo  script include and html tags.  What do people
think?
