show exec command line arguments of ansible-playbook, ansible

[Jakub x]

Hi

I've been thinking what is the best ways of presenting actual command line "row" of the ansible/ansible-playbook execution.

It could be captured 'before execution' with a simple echo, but sometimes the escaping breaks the result (see the example below).

The easiest what I've found is just adding print into ansible-playbook script.

Before I do pull request, etc. - what do You think about it. Any better, easier, or ready-to-use solution?

Note, that presenting args after being parsed with argparse may destroy the view, I do not also wan't to see variables form vault that may be parsed along way. Just CLI exec+arguments.

ansible-playbook

def main(args):

    ''' run ansible-playbook operations '''

    print args

    (...)

Result:

$ ansible-playbook -i ~/ansible/etc/inv/inventory etc/playbooks/playbook.yml -e "system_version=../system_version/prd_default"  -D  -e '{"some_key": {"some_other_key": "x12"}}'            

['-i', '/home/useri/ansible/etc/inv/inventory', 'etc/playbooks/playbook.yml', '-e', 'system_version=../system_version/prd_default', '-D', '-e', '{"some_key": {"some_other_key": "x12"}}' ]  

^^ this result is enough :) If we could have the exact CLI (for further copy-paste execution) would be even better

Broken escaping example:

$ echo ansible-playbook -i ~/ansible/etc/inv/inventory etc/playbooks/playbook.yml -e "system_version=../system_version/prd_default"  -D  -e '{"some_key": {"some_other_key": "x12"}}'   

ansible-playbook -i /home/user/ansible/etc/inv/inventory etc/playbooks/playbook.yml -e system_version=../system_version/prd_default -D -e {"some_key": {"some_other_key": "x12"}}

The above PR adds callback support based on verbosity to print out invocation information.
