``deps`` Guide
|
||
|
|
==============
|
||
|
|
|
||
|
|
|
||
|
|
Using ``deps``
|
||
|
|
^^^^^^^^^^^^^^
|
||
|
|
|
||
|
|
The ``ansible_collections.community.general.plugins.module_utils.deps`` module util simplifies
|
||
|
|
the importing of code as described in :ref:`Importing and using shared code <shared_code>`.
|
||
|
|
Please notice that ``deps`` is meant to be used specifically with Ansible modules, and not other types of plugins.
|
||
|
|
|
||
|
|
The same example from the Developer Guide would become:
|
||
|
|
|
||
|
|
.. code-block:: python
|
||
|
|
|
||
|
|
from ansible_collections.community.general.plugins.module_utils import deps
|
||
|
|
|
||
|
|
with deps.declare("foo"):
|
||
|
|
import foo
|
||
|
|
|
||
|
|
Then in ``main()``, just after the argspec (or anywhere in the code, for that matter), do
|
||
|
|
|
||
|
|
.. code-block:: python
|
||
|
|
|
||
|
|
deps.validate(module) # assuming module is a valid AnsibleModule instance
|
||
|
|
|
||
|
|
By default, ``deps`` will rely on ``ansible.module_utils.basic.missing_required_lib`` to generate
|
||
|
|
a message about a failing import. That function accepts parameters ``reason`` and ``url``, and
|
||
|
|
and so does ``deps```:
|
||
|
|
|
||
|
|
.. code-block:: python
|
||
|
|
|
||
|
|
with deps.declare("foo", reason="foo is needed to properly bar", url="https://foo.bar.io"):
|
||
|
|
import foo
|
||
|
|
|
||
|
|
If you would rather write a custom message instead of using ``missing_required_lib`` then do:
|
||
|
|
|
||
|
|
.. code-block:: python
|
||
|
|
|
||
|
|
with deps.declare("foo", msg="Custom msg explaining why foo is needed"):
|
||
|
|
import foo
|
||
|
|
|
||
|
|
``deps`` allows for multiple dependencies to be declared:
|
||
|
|
|
||
|
|
.. code-block:: python
|
||
|
|
|
||
|
|
with deps.declare("foo"):
|
||
|
|
import foo
|
||
|
|
|
||
|
|
with deps.declare("bar"):
|
||
|
|
import bar
|
||
|
|
|
||
|
|
with deps.declare("doe"):
|
||
|
|
import doe
|
||
|
|
|
||
|
|
By default, ``deps.validate()`` will check on all the declared dependencies, but if so desired,
|
||
|
|
they can be validated selectively by doing:
|
||
|
|
|
||
|
|
.. code-block:: python
|
||
|
|
|
||
|
|
deps.validate(module, "foo") # only validates the "foo" dependency
|
||
|
|
|
||
|
|
deps.validate(module, "doe:bar") # only validates the "doe" and "bar" dependencies
|
||
|
|
|
||
|
|
deps.validate(module, "-doe:bar") # validates all dependencies except "doe" and "bar"
|
||
|
|
|
||
|
