# Ansible module to read a value from an Ini file.
|
|
# Usage:
|
|
# - ini: path=/path/to/file.ini section=default key=something
|
|
# register: my_ini
|
|
#
|
|
# This will read the `path/to/file.ini` file and read the `Hello!` value under:
|
|
# [default]
|
|
# something = Hello!
|
|
#
|
|
# You can register the result and use it later with `{{ my_ini.value }}`
