Build Status

build_barback

Allows wrapping up a Builder as a Transformer so that it can be run in pub or vice-versa.

Using a Builder from Pub

Wrap the Builder instance with new BuilderTransformer(builder) and use it like any other Transformer. The Builder used this way must follow the rules of other Transformers, it cannot use inputs from outside the package where the Transformer is specified in pubspec.yaml

Using an exisiting Transformer with package:build

Wrap the Transformer instance with new TransformerBuilder(transformer) and run as any other Builder. The Transformer instance used this way must follow the rules of other Builders:

  • It cannot overwrite files it uses as inputs.
  • It must know before building what the outputs will be (it must be a DeclaringTransformer).

Changelog

0.5.0+4

  • Support package:analyzer 0.32.0.

0.5.0+3

  • Support the latest analyzer package.

0.5.0+2

  • Update to package:build version ^0.12.0.

0.5.0+1

  • Stop casting BuildStep to BuildStepImpl and remove src import from package:build.

0.5.0

  • Internally uses AnalysisOptions with the following changes:
    • Does not preserveFunctionBodies.
    • Does preserveComments (the default).
    • Uses strongMode.

This makes the resolver implementation identical to the experience using the bazel_codegen, but it is technically a breaking change if you relied on the current behavior.

0.4.0+2

  • TransformerAssetReader#findAssets now returns a Stream<AssetId> to match the latest build package, but this isn't considered a breaking change since the api is unsupported and throws in this implementation.

0.4.0+1

  • Use a single ResourceManager for all calls to runBuilder in BuilderTransformer. This makes Resources be shared across all build steps for a given package and Builder.

0.4.0

  • Breaking: Resolver interface updated for breaking change in package:build v0.10.0

0.3.0

  • Breaking BuilderTransformer is now an AggregateTransformer. This should be transparent for most use cases but could have errors if an instance was assigned to a variable of type Transformer.
  • Breaking BuilderTransformer no longer accepts a Resolvers instance, instead it will create and manage Resolvers on its own.

0.2.0

  • Update to build 0.9.0
  • Breaking TransformerBuilder must be constructed with a buildExtension configuration. Transformers wrapped as a builder must have outputs which vary only by input extension.

0.1.2

  • Only use the global log from build
  • Upgrade to build 0.8.0

0.1.1

  • Support the global log from build

0.1.0

Updated to reflect the new support for reading/writing as bytes in the build package, and the removal of the Asset class.

New Features

  • BuilderTransformer now supports wrapping transformers that read or write their inputs as bytes.
  • The Resolver implementation now has isLibrary to check whether an Asset is a Library and throws an exception rather than returns null on getLibrary when it isn't

Breaking Changes

  • Stopped exporting lib/src/util/barback.dart which contains internal only utilities. Specifically, the following items are no longer public (some are deleted entirely or had breaking changes as well):
    • toBarbackAsset
    • toBarbackAssetId
    • toBarbackTransform
    • toBuildAsset
    • toBuildAssetId
    • toTransformLogger
    • BuildStepTransform

0.0.3

  • Prevent asset writing from escaping beyond the complete() call in BuildStepImpl

0.0.2

  • Fix a bug forwarding logs from a BuilderTransformer

0.0.1

  • Initial separate release - split off from build package.
