Don't compare to empty string

  • Use `when: var | length > 0` instead of `when: var != ""`.
  • Use `when: var | length == 0` instead of `when: var == ""`.

Don't compare to literal True/False

Instead of

when: (foo == 1 and bar == 0) == false

use

when: not (foo == 1 and bar == 0)

Sometimes fixed by adding

changed_when: false


Lines should be no longer than 160 chars

ignore for now?


Shells that use pipes should set the pipefail option

shell: |
  set -o pipefail
  your command
args:
  executable: /bin/bash
