callback: unixy

author: Allyson Bowles <@akatch>
short_description: condensed Ansible output
version_added: 2.5
description:
- Consolidated Ansible output in the style of LINUX/UNIX startup logs.
extends_documentation_fragment:
- default_callback
requirements:
- set as stdout in configuration
'''
from ansible.plugins.callback import CallbackBase
from ansible.utils.color import colorize, hostcolor
from ansible import constants as C
from os.path import basename
class CallbackModule(CallbackBase):
'''
Design goals:
- Print consolidated output that looks like a *NIX startup log
- Defaults should avoid displaying unnecessary information wherever possible
TODOs:
- Only display task names if the task runs on at least one host
- Add option to display all hostnames on a single line in the appropriate result color (failures may have a separate line)
- Consolidate stats display
- Display whether run is in --check mode
- Don't show play name if no hosts found
