Slurp - A Java task runner

Introducing Slurp 1.0. Slurp is a task runner for Java. It allows tasks, aka Runnable instances to be executed.

Slurp was created to be a super simple task runner. It has a lean feature set. Allowing you to register, execute, and run a sequence of tasks.

You can view the Slurp javadocs at ie.briandouglas/slurp/

Usage

Create a SlurpTask

SlurpTasks are Java records. They have a name and a runnable property. Neither the name nor runnable property may be null. You can create a SlurpTask like so.

SlurpTask printHelloWorld = new SlurpTask("HelloWorld", () -> System.out.println("Hello World!"));

Register and Execute a SlurpTask

Inorder to register a SlurpTask for excution a Slurp instance is needed. The Slurp instance allows for tasks to be registered and executed.

Slurp slurp = new Slurp();
SlurpTask printHelloWorld = new SlurpTask("HelloWorld", () -> System.out.println("Hello World!"));

slurp.registerTask(printHelloWorld);
slurp.executeTask(printHelloWorld);

Task names must be unique, if a duplicate task name is registered a DuplicateTaskException will be thrown. If an attempt is made to execute an unknown task a TaskNotFoundException will be thrown.

Executing a sequence of tasks

Slurp can be used to execute a sequence of tasks. Internally it uses a single threaded executor, and waits for each task to finish before executing the next.

String[] sendMarketingEmail = new String[] {
  "prepareClientList",
  "generateEmailHTML",
  "sendSpamMarketingEmail"
};

slurp.executeTaskSequence(sendMarketingEmail); // may also take a SlurpTask[]
