----------------------------------
Summary: Use nested commands in cli
Key: AIRFLOW-3998
URL: https://issues.apache.org/jira/browse/AIRFLOW-3998
Project: Apache Airflow
Issue Type: Improvement
Reporter: Josh Carp
Assignee: Josh Carp
From
https://lists.apache.org/thread.html/94c97ed621706a2e9130a3550b879a5838c23209f2d6d40f8bb49cd8@%3Cdev.airflow.apache.org%3E:
The CLI treats `airflow connection` as a single command, with `--list`,
`--add`, etc. as flags. This means it's possible to pass options that can't be
used together: passing `--list` with `--conn_id` should be invalid. The current
implementation has to handle validation of mutually exclusive options
separately for each command. I think the code would be simpler and easier to
use if we used nested commands instead of flags: `airflow connections list` and
`airflow connections add` would be separate subcommands that would take
different arguments, and we wouldn't have to check for invalid combinations of
commands and arguments.
I'll file a proof of concept patch refactoring the `airflow connections`
command for discussion.
