Suggestion: Unless

[geoah]

I've just discovered angular busy and have fallen in love with it. I'm adding it on buttons, forms, tabs... everywhere hehe. The combination of ng-show="something.$resolved" and cg-busy="something.$promise" has made my day.

The only issue I am currently facing is when I am on a view with ng-busy that is displaying content that resulted from the same promise that is bound on ng-busy. When I try to refresh the data ng-busy sees the promise and shows up the loading sign (as it should). But since I have data showing, I'd like to allow the user to keep seeing them and show the loading somewhere else.

To do so it would require something like cg-busy-unless="something.length>0" so cg-busy doesn't get triggered if length>0. This way I could have 2 cg-busy divs, one for when there is no content (length=0) and one for when there is (length>0).

I am pretty sure there are more things that this could be used for.

ps. Thank you for your amazing work. This is my new favorite ng module! :)

Thanks! I'm glad you like angular-busy.

You can pass any expression to the directive (the result of the expression should just be a promise, or a config object, or falsy value). So you could do something like:

<div cg-busy="something.length === 0 ? something.$promise : null"></div>

I think that should do the trick.
