Pass arguments to code files by writing them to a file before launching.


Dependencies
=============
This driver depends on:

* `Adafruit CircuitPython <https://github.com/adafruit/circuitpython>`_

Please ensure all dependencies are available on the CircuitPython filesystem.
This is easily achieved by downloading
`the Adafruit library and driver bundle <https://circuitpython.org/libraries>`_
or individual libraries can be installed using
`circup <https://github.com/adafruit/circup>`_.


Installing from PyPI
=====================

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally `from
PyPI <https://pypi.org/project/adafruit-circuitpython-argv-file/>`_.
To install for current user:

.. code-block:: shell

    pip3 install adafruit-circuitpython-argv-file

To install system-wide (this may be required in some cases):

.. code-block:: shell

    sudo pip3 install adafruit-circuitpython-argv-file

To install in a virtual environment in your current project:

.. code-block:: shell

    mkdir project-name && cd project-name
    python3 -m venv .venv
    source .env/bin/activate
    pip3 install adafruit-circuitpython-argv-file

Installing to a Connected CircuitPython Device with Circup
==========================================================

Make sure that you have ``circup`` installed in your Python environment.
Install it with the following command if necessary:

.. code-block:: shell

    pip3 install circup

With ``circup`` installed and your CircuitPython device connected use the
following command to install:

.. code-block:: shell

    circup install adafruit_argv_file

Or the following command to update an existing version:

.. code-block:: shell

    circup update

Usage Example
=============

.. code-block:: python

    import supervisor

    from adafruit_argv_file import write_argv

    write_argv("argv_file_otherfile.py", [42, "CircuitPython is Cool", None, [1, 2, 3]])

    print("Launching: argv_file_otherfile.py")
    supervisor.set_next_code_file("argv_file_otherfile.py")
    supervisor.reload()

argv_file_otherfile.py
----------------------
.. code-block:: python

    from adafruit_argv_file import read_argv

    args = read_argv(__file__)
    print(args)
