Research direction

Start by reviewing the existing invoke --list CLI output and the linked discussion #1018. Clarify the native task-selection interaction and its scope, then identify the CLI entry point that owns task listing. Done means users can select a task through Invoke itself rather than an ad-hoc wrapper, with the behavior agreed in the discussion.

Description

Discussed in https://github.com/pyinvoke/invoke/discussions/1018

Originally posted by charudatta10 January 16, 2025
A terminal user interface to select task similar to one implemented in just using just --choose command. I had implemented ad-hoc solution as follow:

@task
def default(c):
    # Run `invoke --list` to get a list of tasks
    result = subprocess.run(['invoke', '--list'], capture_output=True, text=True)
    tasks_output = result.stdout

    # Parse the tasks from the output
    tasks = []
    for line in tasks_output.split('\n'):
        if line.strip() and not line.strip().startswith('Available tasks'):
            task_name = line.strip().split(' ')[0]
            tasks.append(task_name)

    # Display tasks to the user
    print("Choose a task:")
    for i, task_name in enumerate(tasks, 1):
        print(f"{i}: {task_name}")

    # User selects a task
    choice = int(input("Enter the number of your choice: "))
    task_name = tasks[choice - 1]
    c.run(f"invoke {task_name}")
