source_gen 0.7.4 source_gen: ^0.7.4 copied to clipboard
Automated source code generation for Dart.
0.7.4 #
-
Added
typeNameOf
, which is a safe way to get the name of aDartType
, even when the type is aFunctionType
, which has anull
name in newer versions of the Dart analyzer. -
Added
LibraryReader.pathToUrl(Uri|String)
, which computes theimport
orexport
path necessary to reach the provided URL from the current library. Also addedpathToAsset
andpathToElement
as convenience functions. -
Expanded
package:build
support to allow version0.12.0
.
0.7.3 #
- Allow null and empty outputs form
GeneratorForAnnotation
.
0.7.2+1 #
- Allow
package:build
version 0.11.0
0.7.2 #
- Support an optional
header
argument toPartBuilder
andLibraryBuilder
.
0.7.1 #
Generator{ForAnnotation}
#
- Return type of
generate{ForAnnotatedElement}
is nowFutureOr<String>
.
LibraryReader
#
- Added
annotatedElements
to return all elements annotated with something. - Added
classElements
getter for returning allclass
-es in a library.
TypeChecker
#
- Added
hasAnnotationOf
andhasAnnotationOfExact
.
ConstantReader
#
- Added
isAny
(for consistency, but deprecated) andisLiteral
. - Added
literalValue
as an alias for the now deprecatedanyValue
. - Allow
literalValue
to returnnull
if the value is actuallynull
. - Fixed a bug where a
Symbol
would return as aString
foranyValue
. - Fixed a bug where a
List
andMap
were not considered literals.
0.7.0 #
-
Breaking changes: See the wiki for help upgrading.
Generator.generate
now operates on aLibraryReader
rather than being called for everyElement
within a library. Generators can iterate over elements usingLibraryReader.allElements
.GeneratorForAnnotation
will continue to callgenerateForAnnotatedElement
repeatedly for each element.GeneratorForAnnotation
passes in aConstantReader
for the annotation instance rather than re-creating it using mirrors.GeneratorBuilder
is replaced withPartBuilder
andLibraryBuilder
depending on whether the output is meant to be included in apart
file.- Removed
JsonSerializable
and related classes. These are moved topackage:json_serializable
. - Removed
lib/builder.dart
. Import throughsource_gen.dart
instead. - Removed
OutputFormatter
typedef.
-
Add
LibraryReader.allElements
- a utility to iterate across allElement
instances contained in Dart library. -
Add
LibraryReader.element
to get back to theLibraryElement
instance. -
Add
ConstantReader.objectValue
to get back to theDartObject
instance. -
Add
ConstantReader.peek
to read a value that returnsnull
if not found:
// Tries to read the field "token" first, then "_token".
findTokenField(DartObject o) {
final reader = new ConstantReader(o);
final token = o.peek('token') ?? o.read('_token');
}
- Add
throwOnUnresolved
optional parameter toTypeChecker.annotationsOf
,TypeChecker.annotationsOfExact
,TypeChecker.firstAnnotationOf
, andTypeChecker.firstAnnotationOfExact
. Setting this tofalse
will enable you to check for matching annotations with incomplete type information (at your own risk). - Builder logs now log the primary inputs
AssetId
instead of thelibrary
, which is more useful for tracking down the actual files.
0.6.1+1 #
- Tighten constraint on
source_span
.
0.6.1 #
- Added
spanForElement
; returns aSourceSpan
for an analyzerElement
. - Logs a warning to the console when a
GeneratorBuilder
outputs a part file for a given input, but that input does not definepart 'name.g.dart';
.
0.6.0 #
- Breaking change:
TypeChecker#annotationsOf|firstAnnotationOf
now returns annotations that are assignable to theTypeChecker
's type. As a result we've added#annotationsOfExact|firstAnnotationOfExact
which has the old behavior for precise checks. TypeChecker#annotations...
-methods now throw aStateError
if one or more annotations on an element are not resolvable. This is usually a sign of a misspelling, missing import, or missing dependency.- Added
TypeChecker.any
, which delegates to multiple otherTypeChecker
implementations when making a type check.
0.5.10+1 #
- Update minimum
analyzer
package to0.29.10
.
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
: importsource_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 aspart of
can refer to a path. To opt-in,GeneratorBuilder
now has a new flag,requireLibraryDirective
. Set it tofalse
, and also set yoursdk
constraint appropriately:sdk: '>=1.25.0 <2.0.0'
-
Added
LibraryReader
, a utility class forLibraryElement
that exposes high-level APIs, includingfindType
, which traversesexport
directives for publicly exported types. For example, to findGenerator
frompackage: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 byDartObject
from theanalyzer
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()}); }

Breaking: Switch to the
build
package for runningGenerator
s. This means that the top levelbuild
andgenerate
functions are no longer available, and have been replaced by the top levelbuild
,watch
, andserve
functions from thebuild
package, and theGeneratorBuilder
class. Seetool/build.dart
,tool/watch.dart
, andtool/phases.dart
for usage.- Note that the
build
package is experimental, and likely to change.
- Note that the
-
Breaking: The build package provides an abstraction for reading/writing files via the
BuildStep
class, and that is now also provided toGenerator#generate
andGeneratorForAnnotation#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 theBuildStep
instance to read and write files and thebuild
package will track any files you read in and run incremental rebuilds as necessary.
