Previously, the error messages coming out of the Dart transformer were
opaque when those errors came from the analyzer (for example, analyzer
parse errors). Log more useful errors when they are caught by the
transform code.
BREAKING CHANGES:
Dart applications and TypeScript applications meant to transpile to Dart must now
import `package:angular2/bootstrap.dart` instead of `package:angular2/angular2.dart`
in their bootstrap code. `package:angular2/angular2.dart` no longer export the
bootstrap function. The transformer rewrites imports of `bootstrap.dart` and calls
to `bootstrap` to `bootstrap_static.dart` and `bootstrapStatic` respectively.
When a `Directive` implements a lifecycle interface (e.g. `OnChange` or
`OnInit`), populate its `lifecycle` property if not already populated).
Closes#3181
Enable pregenerated (for Dart) and JIT (for Js) change detectors when
possible. Previously we would always use `DynamicChangeDetector`s, but
these cause megamorphic calls and are therefore much slower.
Closes#502
To support interface-based lifecycle methods (#2220), we need to be able
to query for the `interface`s a class supports. Record implemented
interfaces to allow mirror-less querying at runtime.
Closes#2204
Removes `.ng_deps.dart` files which
1. Do not register any `@Injectable` classes
2. Do not call `initReflector` on any other `.ng_deps.dart` files.
Closes#1929
Update the `TemplateCompile` step to use the full render `Compiler`.
Provide `DirectiveMetadata` for `ViewDefinition` objects and use it to
run the `DirectiveParser` step of the render compile pipeline.
Add a step that reads `DirectiveMetadata` object off annotated classes
into `.ng_meta.dart` files. These will be used by the `TemplateCompiler`
step as inputs to the Angular 2 render compiler.
Update one test to avoid unsupported functionality, format others.
Add two transform parameters to aid in debugging the transformer
- `mirror_mode`, with values {`debug`, `none`, and `verbose`}
- `init_reflector`, with values {`true`, `false`}
`mirror_mode`:
- `debug`: Allow reflective access, but log a message if it is used
- `none`: Remove reflective access, `throw` if it is used. Default value
- `verbose`: Allow reflective access, log a stack trace if it is used
`init_reflector`: Whether to generate calls to our generated
`initReflector` code.
These will be useful to reveal areas where the transformer is not generating
appropriate code and to quickly see where reflective accesses occur.
When the pub mode is `transform_dynamic`, we run in MirrorMode.debug
with `init_reflector = false`. This is used for testing purposes.
Create a method that recursively walks imports from an entry point and
determines where classes are registered.
Use this information to determine if a particular annotation implements or
extends Injectable or Template.
- Allow the user to specify multiple entry points to an app.
- Allow the Angular 2 transformer to run without explicit entry points to
generate necessary setters & getters on built-in directives like `For`
and `If`.
Closes#1246
Add a transformer for `di` which generates `.ng_deps.dart` files for all
`.dart` files it is run on. These `.ng_deps.dart` files register
metadata for any `@Injectable` classes.
Fix unit tests for changes introduced by the di transformer.
When using `pub (build|serve) --mode=ngstatic`, we will also generate
getters and setters, parse templates, and remove import of `dart:mirrors`
in the Angular transform. Because this is still relatively immature, we
use the mode to keep it opt-in for now.
Closes#700
