# this is a bit of an advanced topic.
|
|
#
|
|
# generally Ansible likes to pass simple key=value arguments to modules. It
|
|
# occasionally comes up though that you might want to write a module that takes
|
|
# COMPLEX arguments, like lists and dictionaries.
|
|
#
|
|
# In order for this to happen, at least right now, it should be a Python
|
|
# module, so it can leverage some common code in Ansible that makes this easy.
|
|
# If you write a non-Python module, you can still pass data across, but only
|
|
# hashes that do not contain lists or other hashes. If you write the Python
|
|
# module, you can do anything.
|
|
#
|
|
# note that if you were to use BOTH the key=value form and the 'args' form for
|
|
# passing data in, the behaviour is currently undefined. Ansible is working to
|
|
# standardize on returning a duplicate parameter failure in this case but
|
|
# modules which don't use the common module framework may do something
|
|
# different.
