- Changes the `alreadyChecked` flag of AbstractChangeDetector to a new `state` flag.
- Changes all checks of alreadyChecked to check that the state is NeverChecked.
- Set state to Errored if an error is thrown during detection.
- Skip change detection for a detector and its children when the state is Errored.
- Add a test to validate this fixes issue #4323.
Closes#4953
Match [ViewResolver][]'s semantics for reading template and style values
from `@Component` and `@View` annotations.
We now warn if template and/or style values appear on an `@Component`
annotation and a `@View` annotation is present.

Previously, importing a library twice using different prefixes could
cause the template compiler step to incorrect omit `Directive`
dependencies provided by that library.
Previously, we parsed dependencies out of a the stringified value of
`directives`, which is brittle and error-prone.
Move this parsing into `DirectiveProcessor` where we have the full Dart
ast to help.
Previously, `DeferredRewriter` checked for the existence of
`.ng_deps.dart` files to determine which deferred libraries it needed to
rewrite, requiring that those assets exist at the time it was run.
Update to check for `.ng_meta.json` files instead, which exist after the
`DirectiveProcessor` phase. This allows the `DeferredRewriter` (which
only processes *.dart files) to run in
parallel with `TemplateComplier` (which only processes *.ng_meta.json
files) and `StylesheetCompiler` (which only processes *.css files).
Have DeferredRewriter to check existence of .ng_meta.json assets rather than .ng_deps.dart assets
Update `DirectiveProcessor` and `TemplateCompiler` to generate the
getters, setters, and methods currently generated in `BindGenerator`.
Update `DirectiveMetadataLinker` to output `.ng_meta.json` files instead
of `.ng_deps.dart` files, avoiding full codegen until the last phase.
This allows us to dedupe codegen logic and remove an additional phase
from the transformer.
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.
Closes#3966
This change moves many APIs to the angular2/core export.
This change also automatically adds FORM_BINDINGS in
the application root injector.
BREAKING CHANGE:
Many dependencies that were previously exported from specific
APIs are now exported from angular2/core. Affected exports, which
should now be included from angular2/core include:
angular2/forms
angular2/di
angular2/directives
angular2/change_detection
angular2/bootstrap (except for dart users)
angular2/render
angular2/metadata
angular2/debug
angular2/pipes
Closes#3977
When running in Dartium without using transformers (i.e. with a normal
static web server), handle relative template URLs. This works by using
mirrors to get the URL of the library where the component class is
defined.
Closes#2771Closes#3743
BREAKING CHANGE (maybe)
Well as long as our customers use public API this should not be a
breaking change, but we have changed import structure as well as
internal names, so it could be breaking.
import:
angular2/annotations => angular2/metadata
Classes:
*Annotations => *Metadata
renderer.DirectiveMetadata => renderer.RendererDirectiveMetadata
renderer.ElementBinder => renderer.RendererElementBinder
impl.Directive => impl.DirectiveMetadata
impl.Component => impl.ComponentMetadata
impl.View => impl.ViewMetadata
Closes#3660
We have Dart code in `angular2` module that ought to be in its own
package. Examples include Dart analysis plugins, and potentially the
transformers (although transformers cannot be moved out just yet).
However, this code is Dart-only and it doesn’t make sense to use JS
directory layout for it. This commit introduces a sub-directory called
`modules_dart`. All modules in this directory are pure Dart packages
using standard pub directory layout. The code in these packages never
gets transpiled. It is directly copied to `dist` unmodified, except an
adjustment in relative paths in `pubspec.yaml` files.
