source_gen 0.6.1 changelog

0.6.1 #

Added spanForElement; returns a SourceSpan for an analyzer Element.
Logs a warning to the console when a GeneratorBuilder outputs a part file for a given input, but that input does not define part 'name.g.dart';.

0.6.0 #

Breaking change: TypeChecker#annotationsOf|firstAnnotationOf now returns annotations that are assignable to the TypeChecker's type. As a result we've added #annotationsOfExact|firstAnnotationOfExact which has the old behavior for precise checks.
TypeChecker#annotations...-methods now throw a StateError if one or more annotations on an element are not resolvable. This is usually a sign of a mispelling, missing import, or missing dependency.
Added TypeChecker.any, which delegates to multiple other TypeChecker implementations when making a type check.

0.5.10+1 #

Update minimum analyzer package to 0.29.10.

0.5.10 #

Bug fixes:
- Do not fail when "library" is omitted but nothing would be output.
- Do not fail on extensions that don't end in ".dart" (valid use case).

0.5.9 #

Update the minimum Dart SDK to 1.22.1.
Deprecated builder.dart: import source_gen.dart instead.

Added TypeChecker, a high-level API for performing static type checks:

import 'package:analyzer/dart/element/type.dart';
import 'package:source_gen/source_gen.dart';
  
void checkType(DartType dartType) {
  // Checks compared to runtime type `SomeClass`.
  print(const TypeChecker.forRuntime(SomeClass).isExactlyType(dartType));
    
  // Checks compared to a known Url/Symbol:
  const TypeChecker.forUrl('package:foo/foo.dart#SomeClass');
    
  // Checks compared to another resolved `DartType`:
  const TypeChecker.forStatic(anotherDartType);
}

Failing to add a library directive to a library that is being used as a generator target that generates partial files (part of) is now an explicit error that gives a hint on how to name and fix your library:
```
> Could not find library identifier so a "part of" cannot be built.
>
> Consider adding the following to your source file:
>
> "library foo.bar;"
```
In Dart SDK >=1.25.0 this can be relaxed as part of can refer to a path. To opt-in, GeneratorBuilder now has a new flag, requireLibraryDirective. Set it to false, and also set your sdk constraint appropriately:
```
  sdk: '>=1.25.0 <2.0.0'
```
Added LibraryReader, a utility class for LibraryElement that exposes high-level APIs, including findType, which traverses export directives for publicly exported types. For example, to find Generator from package:source_gen/source_gen.dart:
```
void example(LibraryElement pkgSourceGen) {
  var library = new LibraryReader(pkgSourceGen);
  
  // Instead of pkgSourceGen.getType('Generator'), which is null.
  library.findType('Generator');
}
```

Added ConstantReader, a high-level API for reading from constant (static) values from Dart source code (usually represented by DartObject from the analyzer package):

abstract class ConstantReader {
  factory ConstantReader(DartObject object) => ...
  
  // Other methods and properties also exist.
  
  /// Reads[ field] from the constant as another constant value.
  ConstantReader read(String field);
  
  /// Reads [field] from the constant as a boolean.
  ///
  /// If the resulting value is `null`, uses [defaultTo] if defined.
  bool readBool(String field, {bool defaultTo()});
  
  /// Reads [field] from the constant as an int.
  ///
  /// If the resulting value is `null`, uses [defaultTo] if defined.
  int readInt(String field, {int defaultTo()});
  
  /// Reads [field] from the constant as a string.
  ///
  /// If the resulting value is `null`, uses [defaultTo] if defined.
  String readString(String field, {String defaultTo()});
}

0.5.8 #

Add formatOutput optional parameter to the GeneratorBuilder constructor. This is a lambda of the form String formatOutput(String originalCode) which allows you do do custom formatting.

0.5.7 #

Support for package:analyzer 0.30.0

0.5.6 #

Support for package:build 0.9.0

0.5.5 #

Support package:build 0.8.x
Less verbose errors when analyzer fails to resolve the input.

0.5.4+3 #

Support the latest release of pkg/dart_style.

0.5.4+2 #

Use the new log field instead of the deprecated buildStep.logger

0.5.4+1 #

Give more information when dartfmt fails.

0.5.4 #

Update to latest build, build_runner, and build_test releases.

0.5.3+2 #

BugFix: Always release the Resolver instance, even when generation does not run

0.5.3+1 #

Don't throw when running against a non-library asset and getting no LibraryElement

0.5.3 #

Add matchTypes method. As with anything imported from /src/ this is use-at-your-own-risk since it is not guaranteed to be stable
Internal cleanup
- Drop some unused utility methods
- Move cli_util to dev_dependencies
- Avoid some deprecated analyzer apis
- Syntax tweaks
- Drop results.dart which had no usages

0.5.2 #

Use library URIs (not names) to look up annotations in the mirror system.

Generate valid strong-mode code for typed lists.

Remove an outdated work-around.
Make strong-mode clean.

0.5.0+1 #

Support the latest version of pkg/build.

0.5.0 #

Breaking: Switch to the build package for running Generators. This means that the top level build and generate functions are no longer available, and have been replaced by the top level build, watch, and serve functions from the build package, and the GeneratorBuilder class. See tool/build.dart, tool/watch.dart, and tool/phases.dart for usage.
- Note that the build package is experimental, and likely to change.
Breaking: The build package provides an abstraction for reading/writing files via the BuildStep class, and that is now also provided to Generator#generate and GeneratorForAnnotation#generateForAnnotatedElement as a second argument.
Timestamps are no longer included in generated code.
There is no longer a need to specify the files related to an individual generator via AssociatedFileSet. Simply use the BuildStep instance to read and write files and the build package will track any files you read in and run incremental rebuilds as necessary.
