Subject Re: (CB-2600) Mobile Spec cordova.js only works for Android and IOS
Date Wed, 20 Mar 2013 19:20:24 GMT
I consider this change a stop-gap until we have a CLI-based mobile-spec app
to work with.

Before the change, the project is broken by default and requires you to
copy in a script for it to work.

After the change, it's still broken by default, but now allows you to have
a script-per-platform, so that can run the mobile-spec on multiple
platforms without mistakenly including the wrong platform's cordova.js in
it.

E.g. workflow:
jake && cp pkg/* ../cordova-mobile-spec

instead of
jake && cp pkg/cordova.ios.js ../cordova-mobile-spec/cordova-SOME_VERSION.js
and having to re-run each time you switch platforms.


I think I do recall now that synchronous xhrs throw exceptions when they
fail. try/catch addresses this.
