build 0.7.1

A build system for Dart.

0.7.1

• Add a top-level log getter which is scoped to running builds and can be used anywhere within a build rather than passing around a logger. This replaces the BuildStep.logger field.
• Deprecate BuildStep.logger - it is replaced by log
• Deprecate ManagedBuildStep, all build runs should go through runBuilders.

0.7.0

A number of changes to the apis, primarily to support reading/writing as bytes, as this is going to inevitably be a required feature. This will hopefully be the last breaking change before the 1.0 release, but it is a fairly large one.

New Features

• The AssetWriter class now has a Future writeAsBytes(AssetId id, List<int> bytes) method.
• The AssetReader class now has a Future<List<int>> readAsBytes(AssetId id) method.
• You no longer need to call Resolver#release on any resolvers you get from a BuildStep (in fact, the Resolver interface no longer has this method).
• There is now a BuildStep#resolver getter, which resolves the primary input, and returns a Future<Resolver>. This replaces the BuildStep#resolve method.
• Resolver has a new isLibrary method to check whether an asset is a Dart library source file before trying to resolve it's LibraryElement

Breaking Changes

• The Asset class has been removed entirely.
• The AssetWriter#writeAsString signature has changed to Future writeAsString(AssetId id, String contents, {Encoding encoding}).
• The type of the AssetWriterSpy#assetsWritten getter has changed from an Iterable<Asset> to an Iterable<AssetId>.
• BuildStep#input has been changed to BuildStep#inputId, and its type has changed from Asset to AssetId. This means you must now use BuildStep#readAsString or BuildStep#readAsBytes to read the primary input, instead of it already being read in for you.
• Resolver no longer has a release method (they are released for you).
• BuildStep#resolve no longer exists, and has been replaced with the BuildStep#resolver getter.
• Resolver.getLibrary will now throw a NonLibraryAssetException instead of return null if it is asked to resolve an impossible library.

Note: The changes to AssetReader and AssetWriter also affect BuildStep and other classes that implement those interfaces.

0.6.3

• Add hook for build_barback to write assets from a Future

0.6.2

• Remove unused dependencies

0.6.1

• BuildStep now implements AssetReader and AssetWriter so it's easier to share with other code paths using a more limited interface.

0.6.0

• BREAKING Move some classes and methods out of this package. If you are using build, watch, or serve, along with PhaseGroup and related classes add a dependency on build_runner. If you are using BuilderTransformer or TansformerBuilder add a dependency on build_barback.
• BREAKING Resolvers is now an abstract class. If you were using the constructor const Resolvers() as a default instance import build_barback and used const BarbackResolvers() instead.

0.5.0

• BREAKING BuilderTransformer must be constructed with a single Builder. Use the MultiplexingBuilder to cover cases with a list of builders
• When using a MultiplexingBuilder if multiple Builders have overlapping outputs the entire step will not run rather than running builders up to the point where there is an overlap

0.4.1+3

• With the default logger, print exceptions with a terse stack trace.
• Provide a better error when an inputSet package cannot be found.
• Fix dev_dependencies so tests run.

0.4.1+2

• Stop using removed argument useSharedSources when constructing Resolvers
• Support code_transformers 0.5.x

0.4.1+1

• Support analyzer 0.29.x

0.4.1

• Support analyzer 0.28.x

0.4.0

• BREAKING BuilderTransformer must be constructed with a List
• Simplifies Resolver interface so it is possible to add implementations which are less complex than the one from code_transformers.
• Adds a Resolvers class and support for overriding the concrete Resolver that is used by build steps.
• Updates some test expectations to match the new behavior of analyzer.

0.3.0+6

• Convert packages paths in the file watcher to their absolute paths. This fixes #109.

0.3.0+5

• Fix duplicate logs issue when running as a BuilderTransformer.

• Support crypto 2.0.0.

0.3.0+4

• Add error and stack trace to log messages from the BuilderTransformer.

0.3.0+3

• Fixed BuilderTransformer so that logs are passed on to the TransformLogger.

0.3.0+2

• Enable serving files outside the server root by default (enables serving files from other packages).

0.3.0+1

• Fix an AssetGraph bug where generated nodes might be created as non-generated nodes if they are attempted to be read from previous build steps.

0.3.0

• BREAKING Renamed values of three enums to be lower-case: BuildType, BuildStatus, and PackageDependencyType.
• Updated to crypto ^1.0.0.
• Added option to resolve additional entry points in buildStep.resolve.
• Added option to pass in a custom Resolvers instance.

0.2.1

• Added the deleteFilesByDefault option to all top level methods. This will skip the prompt to delete files, and instead act as if you responded y.
  • Also by default in a non-console environment the prompt no longer exists and it will instead just exit with an error.
• Added support for multiple build scripts. Each script now has its own asset graph based on a hash of the script uri.
  • You need to be careful here, as you can get in an infinite loop if two separate build scripts keep triggering updates for each other.
  • There is no explicit link between multiple scripts, so they operate as if all changes from other scripts were user edits. This will usually just do the "right thing", but may result in undesired behavior in some circumstances.
• Improved logging for non-posix consoles.

0.2.0

• Updated the top level classes to take a PhaseGroup instead of a List<List<Phase>>.
• Added logic to handle nested package directories.
• Basic windows support added, although it may still be unstable.
• Significantly increased the resolving speed by using the same sources cache.
• Added a basic README.
• Moved the .build folder to .dart_tool/build. Other packages in the future may also use this folder.

0.1.4

• Added top level serve function.
  • Just like watch, but it provides a server which blocks on any ongoing builds before responding to requests.
• Minor bug fixes.

0.1.3

• Builds are now fully incremental, even on startup.
  • Builds will be invalidated if the build script or any of its dependencies are updated since there is no way of knowing how that would affect things.
• Added lastModified to AssetReader (only matters if you implement it).

0.1.2

• Exposed the top level watch function. This can be used to watch the file system and run incremental rebuilds on changes.
  • Initial build is still non-incremental.

0.1.1

• Exposed the top level build function. This can be used to run builds.
  • For this release all builds are non-incremental, and delete all previous build outputs when they start up.
  • Creates a .build directory which should be added to your .gitignore.
• Added resolve method to BuildStep which can give you a Resolver for an AssetId.
  • This is experimental and may get moved out to a separate package.
  • Resolves the full dart sdk so this is slow, first call will take multiple seconds. Subsequent calls are much faster though.
  • Will end up marking all transitive deps as dependencies, so your files may end up being recompiled often when not entirely necessary (once we have incremental builds).
• Added listAssetIds to AssetReader (only matters if you implement it).
• Added delete to AssetWriter (also only matters if you implement it).

0.1.0

• Initial version
