deno task descriptions

[jespertheend]

I think it could be nice to have a way to describe what tasks do. I realise it is possible to add comments above the tasks when, but I'm specifically looking for a way to show the descriptions when running deno task (without specifying a task).

The commands from tasks are often not very readable, so if a user is new to a repository it can be hard to find the task you're looking for. And having to open deno.json just to see the comments is not ideal.

I'm thinking maybe the comments themselves can be used for printing descriptions. But I reckon this might make things a lot more difficult to parse. So perhaps something like this is more appropriate:

{
    "tasks": {
        "test": "deno test --no-check -A",
        "check": {
            "description": "Performs several checks that are needed before committing.",
            "command": "deno test & deno fmt & deno lint"
        }
    }
}

By the way, I would personally be fine with completely hiding the command for tasks that have a description. It would remove a lot of visual clutter. It might not be the best security wise, but generally speaking if I'm running tasks from a project, I already trust the project enough to not worry about any malicious commands.
