@axelrindle As of now it is not possible. There has been some discussion on lifecycle hooks for v3. See #1273 . If you have suggestions of how you'd like to improve this behavior it would be great.
from cli.
The concept of lifecycle hooks sounds great to me. I'd like to propose the following:
beforeFlags
(runs before flags are parsed)afterFlags
(runs after flags are parsed, but before commands are run)beforeCommand
(runs before command actions are run; maybe merge with the previous?)afterCommand
(runs after a command action has been run)
from cli.
@axelrindle I'm going to move this conversation to #1273 and close this issue
from cli.
