tasks

In the previous section, we saw that tasks needs to have two parameters: tasks, and hooks:

Class-based tasks

# tasks/hello_world.py

import prism.task
import prism.target

class HelloWorld(prism.task.PrismTask):
    
    def run(self, tasks, hooks):
        test_str = "Hello, world!"
        return test_str

Function-based tasks

# tasks/hello_world.py

from prism.decorators import task

@task()
def hello_world(tasks, hooks):
    test_str = "Hello, world!"
    return test_str

Both are critical for Prism to run, and Prism will throw an error if it finds a task without both parameters.

tasks is an instance of the prism.infra.task_manager.TaskManager class. At the moment this class has the following functions (see the API reference for more information):

• tasks.ref(): for referencing the output of other tasks in your project

Next, we'll cover exactly what these functions do.
