UPGRADE-0.2.md

UPGRADE FROM 0.1 to 0.2

• If you use run the method will always return a Promise (the callback parameter was removed)
• A task can return a Promise. If you do that it will wait until the Promise is resolved before finishing this task otherwise it will finish the task as soon as the task method finishes.
• runTask will always return a promise that will be resolved when the executed task gets called

Common migration examples

Example 1

task("lint:test:unit", function () {
    run("eslint ./test/unit");
});

becomes

task("lint:test:unit", function () {
    return run("eslint ./test/unit");
});

Example 2

task("lint:test:unit", function () {
    run("eslint ./test/unit");
    run("eslint ./test/unit2");
});

becomes (if tasks can run in parallel)

task("lint:test:unit", function () {
    return Pomise.All(
        run("eslint ./test/unit"),
        run("eslint ./test/unit2")
    );
});

or (if tasks need to run in sequence)

task("lint:test:unit", function () {
    return run("eslint ./test/unit")
        .then(function () {
            return run("eslint ./test/unit2");  
        });
});

Example 3

task("lint:test:unit", function () {
    runTask("test");
    run("eslint ./test/unit2");
});

becomes (if tasks can run in parallel)

task("lint:test:unit", function () {
    return Pomise.All(
        runTask("test"),
        run("eslint ./test/unit2")
    );
});

or (if tasks need to run in sequence)

task("lint:test:unit", function () {
    return runTask("test")
        .then(function () {
            return run("eslint ./test/unit2");  
        });
});
