ngRepeat pass collection to transcluded scope

[SimeonC]

In the case of filtered ng-repeats (ng-repeat="type in types | filter: search") it would be really useful to add something like $collection to the transcluded scope at line L276.

Then we could easily access the filtered collection in our ng-clicks and ng-class functions like we access $index.

I imagine it would be changed like the following which wouldn't incur much overhead as it is just passing an object reference:

var updateScope = function(scope, index, collection) {
  scope.$collection = collection;
  ...
};

// then at line 364 and 377
updateScope(block.scope, index, collection);

I could probably run up a PR at some point if this is acceptable?

Something like this has been discussed quite a bit during the meeting today, I can't remember which syntax we decided on, but I believe we'll be adding an alias to the processed (or not) collection with an arbitrary name.

The meeting notes should have details soon.

I believe we landed on:
item in items | filter:'foo' as results track by $index

was there ever an issue # opened about that? it would be good to attach this issue to it

[SimeonC]

Cool, look forward to using it. Thanks for the quick reply.

Not sure if it's documented, but I think @matsko is the one working on it

Here's the PR: #8046

Merged. The feature is now in master as:

<!-- `results` can be called anything -->
<div ng-repeat="item in items | filter:x as results">...<div>
