The directory contains code authored in a style that makes it transpilable to dart. As such, these are not idiomatic examples of Angular 2 usage.
The main purpose of this directory is to enable experimentation with Angular within the angular/angular repository.

Now that we can specify `directives` in either `@View` or `@Component`,
we will try to parse from both.
Previously, we would trash any `directives` parsed in the first
annotation upon encountering the second annotation. This ensures that we
maintain that list of `directives` regardless of annotation ordering.
Handle the situation where a `.dart` file generates a `.ng_meta.json`
file but does not register any reflective information.
An example of this would be a file that defines a const list that looks
like a directive alias. The transformer keeps track of this, and creates
a `.ng_meta.json` file but never creates a `.ng_deps.dart` file, which
can result in other files being linked to it and it not defining an
`initReflector` method.
`DeferredRewriter` depends on the presence of `.ng_deps.dart` files,
which do not yet exist in the phase where it was previously run.
Update the transformer phases to fix this and add an integration test to
prevent regression.
Link `NgDeps` & `NgMeta` data in the same phase to avoid unnecessary asset
creation & reading.
Remove `NgMeta#exports` and instead use `NgDeps#exports` to link `NgMeta` files
in `ng_meta_linker.dart`.
Previously, annotations which were const objects (as opposed to const
instance creation expressions) were incorrectly output as instance
creation expressions.
Before:
```
const override() // A const instance creation expression
```
After
```
override // A const instance
```
Closes#4481
BREAKING CHANGE:
- Removes `ChangeDetection`, use a binding for `ChangeDetectorGenConfig` instead
to configure change detection.
- `RenderElementRef.renderBoundElementIndex` was renamed to `RenderElementRef.boundElementIndex`.
- Removes `ViewLoader`, use `XHRImpl` instead.
Closes#3605
BREAKING CHANGE:
- we don't mark an element as bound any more if it only contains text bindings
E.g. <div>{{hello}}</div>
This changes the indices when using `DebugElement.componentViewChildren` / `DebugElement.children`.
- `@Directive.compileChildren` was removed,
`ng-non-bindable` is now builtin and not a directive any more
- angular no more adds the `ng-binding` class to elements with bindings
- directives are now ordered as they are listed in the View.directives regarding change detection.
Previously they had an undefined order.
- the `Renderer` interface has new methods `createProtoView` and `registerComponentTemplate`. See `DomRenderer` for default implementations.
- reprojection with `ng-content` is now all or nothing per `ng-content` element
- angular2 transformer can't be used in tests that modify directive metadata.
Use `angular2/src/transform/inliner_for_test` transformer instead.
Ensure that the transformers are properly declaring all consumed
outputs. In particular, when a transformer overwrites an output, make
sure the transformer calls `consumePrimary` followed by `addOutput` for
that file.
Prevent `DirectiveLinker` from consuming `.ng_deps.json` files. When we
do this, barback incorrectly calculates the available assets for that
phase, resulting in broken builds.
To simplify processing and testing in the future, use protobufs to
represent of `.ng_deps.dart` files rather than always dealing
directly in Dart code.
This update does not actually use the protobuf representation, but this
is a step towards moving all phases to parse and use protobufs rather than
Dart code.
By default, pipes are pure. This means that an instance of a pipe will be reused and the pipe will be called only when its arguments change.
BREAKING CHANGE
Before:
@Pipe({name: 'date'}) class DatePipe {} defines an impure pipe.
After:
@Pipe({name: 'date'}) class DatePipe {} defines a pure pipe.
@Pipe({name: 'date', pure: false}) class DatePipe {} defines an impure pipe.
