dartle 0.14.0

A simple build system written in Dart. Tasks are declared in a regular Dart file.

Future release

• forbid tasks from accessing IO resources not declared in inputs/outputs.

done, waiting for next release

0.14.0

Dartle Core

• breaking change: refactored FileCollection (incl. file, dir functions). Simplified how collections may be defined.
• added 'PROFILE' log level and logged times of each significant build step.
• cleanup cache entries that are no long relevant after build.
• run post-run actions at end of each TaskPhase instead of only at the end of the build.
• better reporting of which tasks failed at end of build.
• cancel all pending tasks immediately on first build failure.
• deleteOutputs function now works with all instances of FileCondition, not only RunOnChanges.
• new RunCondition implementation: RunToDelete (used to implement cleaning tasks).
• fixed deleteAll so it removes directories after emptying them.
• improved DartleCache so it will not trust timestamps when diff is less than 1 second. Some file systems have low resolution timestamps.
• DartleCache now hashes files by loading small buffer into memory at a time instead of whole file.
• DartleCache hash now distinguishes between empty file and empty directory.

Note: the file collection change was necessary for Dartle to be able to reliably detect build misconfiguration. It was previously next to impossible to determine when tasks had clashing outputs or were missing dependencies given the order in which files are read and written to. The new API is less powerful but should suffice in most cases, and it allows computing the intersection between tasks inputs and outputs reliably... that lets Dartle provide much more powerful diagnostics, getting it closer to providing reproduce-able builds.

Dartle Dart

• breaking change: replaced DartConfig.runBuildRunner with DartConfig.buildRunnerRunCondition.
• improved Dart tasks dependencies to avoid errors in edge cases.

Note: the new DartConfig.buildRunnerRunCondition property allows better control over when the runBuildRunner task runs, which is important as it's an expensive task.

0.12.1

• include custom task phases in information about tasks.

0.12.0

• added build phases to ensure ordering between tasks without dependencies: setup, build, teardown.
• enabled parallelization of tasks by default.

0.11.0

• better error message when no default tasks exist and no tasks are selected.
• new intersection method added to FileCollection.
• made most FileCollection methods more platform-independent (handle path differences better).
• auto-detect dependencies between tasks due to inputs/outputs - error if no explicitly dependency exists.

0.10.0

• ask user whether to create a new Dartle project if executed in directory not containing dartle.dart.
• Dart test task does not bomb when faced with unexpected output.
• fixed #6 - file inputs/outputs are cached separately per task.

0.9.1

• updated Dart test model library.

0.9.0

• new Dart Test reporter - shows better status of running tests and failed tests at the end.
• improved logging of how many tasks will run or are up-to-date.
• improved show-tasks output: includes which tasks would run and why.
• added RunConditionCombiner along with OR and AND implementations.
• #3 Dart lib: runPubGet on pubspec.yaml and lock file changes.

0.8.0

• non-null-by-default release.
• created dartle_dart library.
• compile dartle.dart into executable automatically when running 'dartle' executable.
• improved log messages.

0.6.1

• better 'debug' log level message color.

0.6.0

• improved logging output.
• added option to turn off colorful-log.

0.5.1

• Fixed Dartle version in published package.

0.5.0

• Added CLI --version option.
• Improved help messages.
• Run tasks in parallel when no dependencies force an ordering.
• Use different Isolates to run parallel tasks when their actions is a top-level function and the -p flag is used.
• Let tasks take arguments (e.g. dartle task :arg).
• Verify task's arguments using its ArgsValidator.
• Changed Task action's parameter list to take a non-optional List<String>.
• Fixed bug where not all executable tasks were shown with the -s flag.

0.4.0

• Implemented task dependencies.
• New option to show all build tasks.
• New option to show task graph.
• Use dart2native to compile dartle build file where available.
• Better error handling to avoid crashes.
• Improved process execution functions.
• Fixed RunOnChanges: must run task if its outputs do not exist.
• Changed failBuild function to throw DartleException (not call exit).

0.3.0

• Improved dartle caching.
• Attempt to use fastest snapshot method available to make script runs faster.
• Support choosing tasks by fuzzy name selection.

0.2.0

• Implemented dartle executable. Snapshots dartle.dart in order to run faster.

0.1.0

• Added basic functionality: run tasks, logging.

0.0.0

• Initial version, created by Stagehand
