Async Execution

[agucova]

Is there any way to run two tasks simultaneously?

I'm not sure if this is an intended use case (continuous tasks).

I have a Bakefile like this:

launch/dev: launch/huey launch/flask

launch/huey:
    huey_consumer app.main

launch/flask:
    flask run

And my intention would be to run both launch/huey and launch/flask at the same time when launch/dev is called in, order to test an app.

Use bash to do it!

But given that they are declared as separated tasks, how can I use bash to call both?

I can do this:

launch/dev:
    huey_consumer & flask run

But can bash call a task defined in the Bakefile?

[kennethreitz]

launch/dev:
    bake launch/huey & bake launch/flask

launch/huey:
    huey_consumer app.main

launch/flask:
    flask run

Make sure to use a latest release for this.

This works because bake automatically sets the BAKE_SILENT environment variable for the tasks that run underneath it, which is like passing the bake --silent flag.
