Idem plugin with built-in functions

About
=====

An Idem plugin containing common functions that you can run with the ``exec.run`` state. You can use argument binding to pass the output of these common functions to other Idem plugin resource states, such as in ``idem-aws``, ``idem-k8s``, or other Idem plugins.

What is POP?
------------

This project is built with `pop <https://pop.readthedocs.io/>`__, a Python-based implementation of *Plugin Oriented Programming (POP)*. POP seeks to bring together concepts and wisdom from the history of computing in new ways to solve modern computing problems.

For more information:

* `Intro to Plugin Oriented Programming (POP) <https://pop-book.readthedocs.io/en/latest/>`__
* `pop-awesome <https://gitlab.com/saltstack/pop/pop-awesome>`__
* `pop-create <https://gitlab.com/saltstack/pop/pop-create/>`__

Getting Started
===============

Prerequisites
-------------

* Python 3.7+
* git *(if installing from source or contributing to the project)*

  To contribute to the project and set up your local development environment, see ``CONTRIBUTING.rst`` in the source repository for this project.

Installation
------------

You can install ``idem-core-functions`` with the Python package installer (PyPI) or from source.

Install from PyPI
+++++++++++++++++

.. code-block:: bash

      pip install idem-core-functions

Install from Source
+++++++++++++++++++

.. code-block:: bash

   # clone repo
   git clone git@<your-project-path>/idem-core-functions.git
   cd idem-core-functions

   # Setup venv
   python3 -m venv .venv
   source .venv/bin/activate
   pip install -e .

Usage
=====

Setup
-----

After installation, ``idem-core-functions`` execution modules are accessible to the pop *hub*.

For more information:

* `Intro to Plugin Oriented Programming (POP) <https://pop-book.readthedocs.io/en/latest/>`__
* `pop hub <https://pop-book.readthedocs.io/en/latest/main/hub.html#>`__

You are now ready to use idem-core-functions.

Exec Module
-----------

An SLS file specifies the desired state of a resource. You can run an exec module within an SLS file using the ``exec.run`` state, where the exec module returns a new state that can be referenced with argument binding.

* ``core.encoding.base64encode``

  Apply Base64 encoding to a string.

* ``core.encoding.base64decode``

  Restore a Base64 encoded character string to the original string.

* ``core.conversion.to_json``

  Serialize an object to a string of JSON.

* ``core.collection.distinct``

  For a given list, return a new list with any duplicate elements removed.

* ``core.collection.flatten``

  For a given list, replace any elements that are lists with a flattened sequence of that list.

* ``core.collection.element``

  Retrieve a single element from a list.

* ``core.collection.length``

  Determine the length of a given list, map, or string.
