Replace direct uses of `print` in the transformer with explicit uses of
stderr.
Add a few @override annotations for clarification of other `print`
implementations.
Clarify error message on incorrect custom_annotations value.
Closes#7855
Pt 4 of migrating from package:guinness + package:unittest =>
package:test.
This PR migrates DeferredRewriter & DirectiveMetadataLinker unit tests.
Closes#7703
Update the Angular 2 transformer to recognize
`package:angular2/platform/browser.dart` as the library which exports
the `bootstrap` function.
Update playground, examples, benchmarks, & tests to import bootstrap from
platform/browser.
Closes#7647
TL;DR: Modify pubspec.yaml files to use the recommended "targeted"
transformers. The unified "simple" angular2 transformer still works as
always, but we want to encourage use of the targeted transformers
whereever possible.
See [the wiki](https://github.com/angular/angular/wiki/Advanced-Transformer-Configuration)
for details about targeted transformers.
See #1872
Pt 3 of migrating from package:guinness + package:unittest => package:test.
This PR migrates DirectiveProcessor & InlinerForTest unit tests.
Closes#7475
These were previously not being run.
Bring them up to modern usage, move them to package:test, and include
them in transform.server.spec.dart.
Closes#7463
Create transformers that allow specifying transformer actions on
specific libraries.
* angular2/transform/codegen: Generates all necessary code.
* angular2/transform/reflection_rewriter: Replaces `bootstrap` calls in
application entry points to remove transitive dart:mirrors import,
resulting in smaller code size & faster execution.
* angular2/transform/deferred_rewriter: Rewrites deferred imports and
`loadLibrary` calls to initialize Angular2 and preserve deferred
operation.
Proper configuration of these three transformers can replace the single
angular2 transformer, resulting in significant performance gains for
builds of large angular2 apps.
Update angular2 itself to declare the codegen transformer, since it has
neither deferred imports nor application entry points.
Remove the undocumented & unused quick_transformer.
BREAKING CHANGE:
`OnPushObserve` was an experimental
feature for Dart and had
conceptual performance problems,
as setting up observables is slow.
Use `OnPush` instead.
Our transformer unit tests currently use package:guinness, which uses
package:unittest under the covers. package:unittest has been updated and
renamed package:test, so for simplicity migrate test to use package:test
syntax.
The hello_world app used to measure Dart payload size was broken by a
change in
7ae23adaff.
This breakage does not materially affect the size of the generated code,
(before fix: 298819, after fix: 298825), and since it was a runtime
error it was not noticed & not a problem.
Update the app to work again.
Closes#7358
Issue raised in PR #6745.
Previously, the transformer name conversion functions could return the
input string on unexpected input, which is almost certainly an error.
`throw` in this case instead, so we know early that something has likely
gone wrong.
Closes#6753
Previously, every .dart file in a package was processed to ensure proper
initialization of deferred loaded libraries.
Update the transformer to avoid processing libraries which we know do
not import any deferred libraries.
Closes#6745
Handle some cases which would previously result in broken code.
- Importing bootstrap.dart deferred
- Using combinators when importing bootstrap.dart
- Importing bootstrap.dart with a prefix
Closes#6749
Previously, we generated the code to initialize the reflector into the
<file>.ng_deps.dart and the compiled template and change detector code
into <file>.template.dart.
Update the transformer to generate all code into <file>.template.dart to
avoid the additional HTTP requests necessary when debugging
applications in Dartium.
BEFORE:
The following would throw in the dev mode because `f` would return a new array when called by checkNoChanges.
@Component({
template: `
{{f()}}
`
})
class A {
f() { return [1]; }
}
AFTER:
The checkNoChanges function compares only primitives types for equality, and deeply compares iterables. Other objects cannot cause checkNoChanges to throw. This means that the dev mode would never fail given a legal program, but may allow some illegal programs.
Previously, template codegen was done asynchronously, which could result
in reflector state being overwritten and leading to compile errors.
Update the codegen to run synchronously to ensure this does not happen.
Closes#6603
Adds tests for public Dart and TS frameworks to make sure that
components with templateUrl can be created by the TestComponentBuilder.
Closes#6359Closes#6601
Resolve all invalid field override errors, workaround current
reflection limitations in Dart Dev Compiler. todo, hello_world and
key_events samples now work with Dart Dev Compiler.
BREAKING CHANGE: remove TemplateRef.elementRef setter
Closes#6441
Widen version dependencies for `package:angular`, `package:code_transformers`,
and `package:observe`.
`package:guinness` uses `package:unittest` while
the newest versions of `package:code_transformers` use `package:test`.
This causes our end-to-end Dart transformer tests (which use testing
code in `package:code_transformers`) to be skipped.
To fix this:
- Move e2e tests to run in a separate file
- Run `gulp test.server.dart` tests serially
Closes#5922Closes#5935
Replace uses of `package:code_transformers`, which is only used to
convert from uri to `AssetId`, with calls to the utility methods in
`src/transform/common/url_resolver.dart`.
Closes#5931
