Hey Lennart, Peter, I'll just be lazy and reply to both of you in one email.
>> Great page.

Apart from page being a specific > type of view (just like any specific implmentation) aren't they the > same? (I am one of those newbies) Good point about the page vs. view thing. This nomenclature predates my involvement with Zope 3 even (and I got in around 2002). I think the term "page" was initially associated with something that's HTML, so something that comes out of a page template and is displayed by a browser. I really would like to reuse the simpler directives as much as possible which is why I'm trying to mention <view />. Perhaps we'll have to end up using <browser:view /> because of the layer problem I mention. In analogy, perhaps the browser:pages directive should be named browser:views so that we can ditch the "page" nomenclature once and for all. >> Second thing: >> >> name="index.html" >> vs >> @page(u'update.html') >> >> I think that unless we can move all naming into python (and I'm not >> sure we can) we shouldn't have any naming in Python. Consistency is >> the enemy of confusion! :-) >> > This kinda seems to make sense to me, I thought the same when reading > the proposal but I can see the simplicity of having the names in python > too. It's not only about simplicity, it's also about instrinsic information or not: "...what gets viewed and for what request as well as the names of the actual browser pages, are intrinsic to the implementation. Why are the page names intrinsic? Because the different method refer to each other in URLs, form handlers and redirect calls." > I guess it comes down to whether we believe the names are wiring or > application specific.

This is just an idea. I understand Lennart's concern about the consistency, so I leave it up to Lennart to convince me of something else. >> Third thing: >> "What if someone wants to customize this view by changing the template >> but not the helper method? You either have to subclass this view class >> and add a custom __call__ to your subclass, or you use *named >> templates* from zope.formlib:" >> >> Naaaah. I don't like this, but I can't tell you why. Maybe just >> because it's too complicated. It's not my invention. It's in zope.formlib and it's being used, whether you like it or not :). Seriously, as I point out in my proposal, you can either hardwire the template via ViewPageTemplate or use a loose coupling via NamedTemplate. Btw, I think the name "NamedTemplate" is confusing, "NamedTemplateImplementation" even more (and too long). >> Same goes with your usecase 1.

Good point. > Apart from newbies that are coders are probably most used to python > syntax than ZCML directives.

I'm not sure what you mean by these "tools"... Thanks for the feedback from the both of you.
