batch 0.4.0

A lightweight and powerful Job Scheduling Framework written in Dart. With this framework, you can easily develop job scheduling and batch program in Dart.

Release Note

0.4.0

New Features

• Added onStarted, onSucceeded, onError and onCompleted callbacks for Job, Step and Task.
• Added feature to specify the color of the message when logging out with LogColor and ConsoleColor.
• Improved log message from framework.
• Added convenient method shutdown() to shutdown the application from Task.

Destructive Changes

• Changed to define Precondition as an anonymous function.

0.3.0

New Features

• Added Precondition to check the preconditions for executing Job, Step and Task.
• Conditional branching is now possible for the all layers (Job/Step/Task) based on BranchStatus by using the branchOnSucceeded, branchOnFailed and branchOnCompleted.
• Due to the feature to create branches in Job, the schedule argument of the Job object is no longer required. However, be sure to set up a schedule for the root Jobs.

Destructive Changes

• Changed the type of the argument when specifying Job scheduling. Now you can use CronParser to specify the schedule in Cron format.

0.2.1

New Features

• Added DefaultLogFilter.
• Added Precondition to check the starting condition of Job and Step. It can be specified as an argument when creating Job and Step instances.

Destructive Changes

• Deleted DevelopmentLogFilter and ProductionLogFilter.

0.2.0

New Features

• Added logging feature. Some logs are automatically output to the console during batch processing, but you can output logs at any log level by using the various methods for log output.
• Enabled parameter exchange between tasks in the same step.
• Added the concept of SharedParameters, which are shared by the entire batch application.

Destructive Changes

• Refactored the structure, made JobLauncher private and released BatchApplication as new entry point.
• Added ExecutionContext as an argument to the execute method of the Task class.

0.1.0

• Improved documents.
• Wrapped the return value of execute with Future to allow asynchronous processing in Task. Asynchronous processing defined in Task is safely controlled by the batch library, so you don't need to be aware of it when running JobLauncher.

0.0.1

• First Release!
