angular_compiler

• Update README.md.

• Allow a slightly wider version range in pkg:angular.

• Support null safety
• Require Dart ^2.14.0

• Removed invalid link from the OnPush compatibility warning.
• Update package:analyzer dependency to ^0.40.0.

• Stable release.

• Added a command-line flag, catchMissingDirectives, that when set warns about missing directives or mispelled bindings.

• The old pipe syntax (expression | pipeName:arg) is removed. Please use the new syntax for pipes ($pipe.pipeName(expression, arg)) instead.

• sourceSpanWithLineInfo now includes the surrounding source on the highlighted line(s), with the correct line number(s).

• FactoryProvider admits static methods as its factory function. This is now supported by @GenerateInjector and ReflectiveInjector.

• Hooks NgContentRef Api to Dart. An <ng-content> element can be treated as a psudeo-DOM element and queried if it contains a reference.

• Template expressions are now parsed using package:analyzer and though the subset of expressions supported largely has not changed some expressions that were silently accepted before are now compile-time errors.

• The InjectorReader now fails with an explicit error if types are used inside a ValueProvider object. Previously, using types in ValueProviders would crash the AngularDart compiler.

  Instead of a ValueProvider, use a FactoryProvider for complicated objects, such as those that contain types.

• Removed the i18n compiler flag that was previously used to opt-in to internationalization in templates before the feature had stabilized.

• Added support for a command-line flag, allowed_typedefs_as_di_token. This is intended to be used as a transitional flag to ban using a typedef as a DI token (which has non-predictable properties in Dart 2).

• Added $ChangeDetectionLink, a type checker for matching the experimental @changeDetectionLink annotation.

• Maintenance release to support the newest version of analyzer.

• FormatExceptions thrown while parsing modules in InjectorReader are now rethrown as BuildErrors with source information.

• The InjectorReader will fail earlier in the compile process on parse errors.

• Unhandled errors from InjectorReader are now caught and reported with source information.

• BuildError now has factory constructors to create errors for annotations and elements.

• Updates the messages.unresolvedSource API to support different error messages for each SourceSpan affected.

• Update failure message to include an asset id when collecting type parameters.

• TypedReader now throws a build error when reading a private type argument.

• Catches an (invalid) null token of a provider and throws a better error.

• Catches an (invalid) null value of the function for FactoryProvider.

• Emits all strings for @GeneratedInjector as raw (r'$5.00').

• Supports named arguments for ValueProvider and @GeneratedInjector.

• Prevents InjectorReader.accept() from crashing when given a dependency with no type or token.

New Features

• Added TypedElement to represent a statically parsed Typed.

• TypedReader.parse() now returns a TypedElement.

• Added $Typed, a TypeChecker for Typed.

• Added TypedReader for parsing generic directive types.

• Added support for void and Null types to appear in tokens.

• Added DirectiveVisitor, and removed $HostBinding and $HostListener.

• Added ModuleReader.extractProviderObjects to use in the view compiler.

• Added logFine as a new top-level API.

• Added an internal cli.dart library. See lib/cli.dart for details.

• Added SplitDartEmitter for internal use.

• Added $QueryList as a TypeChecker.

• Expose the $Provider TypeChecker.

• Added typeArgumentOf helper method.

• Added support for recognizing the MultiToken type.

• CompilerFlags now supports as a fast_boot argument; default is true.

• ReflectorEmitter now takes an optional deferredModules{Source}.

• Started adding experimental support for a new Module syntax.

Breaking Changes

• CompilerFlags no longer parses and supports the 'debug' option and genDebugInfo is always false, and is deprecated pending removal in a future version.

• Removes unused APIs of ComponentReader.

• TokenReader no longer supports arbitrary const objects or literals.

• Removed use_new_template_parser flag. The old parser was removed.

• Removed $QueryList.

• Added canRead to NgAssetReader.

• Moved CompilerFlags and Profile to cli.dart.

• linkToReference now requires a second parameter, a LibraryReader, and treats private types (i.e. prefixed with _) as dynamic as the compiler cannot point to them.

• ReflectableEmitter has been completely replaced with a new implementation.

• Removed all references and use of determining a "prefix" of a type. This was no longer used once ReflectableEmitter was re-written.

• Removed a number of internal flags that were no longer strictly required.

• ModuleReader.deduplicateProviders now returns a List not a Set, and providers that are multi are not removed, as it is a feature of the DI system to have multiple of them with the same token.

• Add the TypeLink class, and replace uses of Uri.

• @Component and @Directive annotated classes are no longer @Injectable. In practice this means they can no loger be provided as an implicit const Provider(FooComponent) without either manually adding @Injectable or refactoring your code. We found this didn't really affect users, and most uses of components and directives in these lists were accidental.

Bug Fixes

• Fixed a bug where the compiler crashed after resolving a bound type failed.

• Misspelled or otherwise erroneous annotations on classes now produce a more understandable error message, including the element that was annotated and the annotation that was not resolved.

• Fix a bug where throwFailure hit an NPE without a stack trace.

• linkTypeOf correctly resolves bound types (i.e. <T>) in most cases, and can fallback to dynamic otherwise.

• Removed all remaining (invalid) references to package:barback.

• Prevented a RangeError that occurred when an invalid import lacked an extension.

• ReflectorEmitter now supports MultiToken and generic-typed tokens, with some known limitations. See https://github.com/angulardart/angular/issues/782.

• Fix a bug in the outliner that did not the correct output extension.

• Always link to export "...template.dart" files in initReflector().
• Catch missing field-formal (this.) fields and warn in the compiler.
• Does not emit a registerDependencies function call for empty constructors.
• initReflector() no longer treats @Pipe as an @Injectable service.

• Various changes internal to the compiler.

• Added various classes and helpers to form the new compile infrastructure:
  • ComponentReader
  • DependencyReader, DependencyInvocation, DependencyElement
  • ProviderReader, ProviderElement
  • TokenReader, TypeTokenElement, OpaqueTokenElement
  • getInheritanceHierarchy, urlOf
  • ReflectableReader, ReflectableOutput, ReflectableClass

• Fixed a bug where flag entry_points was only allowed to be a list.

• Initial commit of angular_compiler.
