Tim Kim commented on CB-4036:
-----------------------------
Ok, I've made another pass at this with the commit in the comment above. It's
not fully tested and I'm not even sure if it works right now (have to change
the tests), but I figured I'd push it up just so I could show you all.
Anywho, I went with the idea that we do all of our version checks within the
engine tag. I've also added support such that there are defaults for the
engines we know about (placed in util/default-engines) as well the ability to
add custom engines that need to be checked.
> <platform> tag should have a "version" attribute

> This might be hole that we didn't consider.
> I know implicitly if the plugin supported an "engine" version we support what
> the engine supports, but here could be one scenario.
> For example, with iOS 7, a plugin CDVFooBar use this awesome NSWhizBang
> framework. Fine, with iOS 7, you have to of course build with the iOS 7 SDK,
> and you can support iOS 6 with a Deploy Target build setting.
> It runs on iOS 7 - yay.
> It.. blows up on iOS 6 at runtime, because of course NSWhizBang framework
> does not exist on iOS 6.
> Now you say, why don't you do Obj-C runtime checks and weak link the
> framework? Yes, the plugin author can do that but a plugin user, by parsing
> the plugin xml (using a tool, or optically, whatever) cannot know that the
> plugin does NOT work on iOS 6 - and even though it "runs" on iOS 6, it does
> nothing, which is useless and wastes a lot of time.
> So - my proposal is, to add a *"version"* attribute on the *<platform>* tag.
> It should follow the syntax for the <engine> version attribute.
> What would be the default if the version attribute is not there? Not sure
> what a reasonable default is yet.
