Script creates a project with the MVC pattern
=============================================

.. versionadded:: 1.0.0

.. seealso::

    `MVC pattern <https://en.wikipedia.org/wiki/Model–view–controller>`_

.. rubric:: Use a clean architecture for your applications.

.. image:: https://github.com/HeaTTheatR/KivyMD-data/raw/master/gallery/kivymddoc/preview-mvc.png
    :align: center

Use a clean architecture for your applications. KivyMD allows you to quickly
create a project template with the MVC pattern. So far, this is the only
pattern that this utility offers. You can also include database support in
your project. At the moment, support for the Firebase database
(the basic implementation of the real time database) and RestDB
(the full implementation) is available.

Project creation
----------------

Template command::

    python -m kivymd.tools.patterns.create_project \\
        name_pattern \\
        path_to_project \\
        name_project \\
        python_version \\
        kivy_version

Example command::

    python -m kivymd.tools.patterns.create_project \\
        MVC \\
        /Users/macbookair/Projects \\
        MyMVCProject \\
        python3.10 \\
        2.1.0

This command will by default create a project with an MVC pattern.
Also, the project will create a virtual environment with Python 3.10,
Kivy version 2.1.0 and KivyMD master version.

.. note::
    Please note that the Python version you specified must be installed on your
    computer.

    :align: center

Creating a project using a database
-----------------------------------

.. note::
    Note that in the following command, you can use one of two database names:
    'firebase' or 'restdb'.

Template command::

    python -m kivymd.tools.patterns.create_project \\
        name_pattern \\
        path_to_project \\
        name_project \\
        python_version \\
        kivy_version \\
        --name_database

Example command::

    python -m kivymd.tools.patterns.create_project \\
        MVC \\
        /Users/macbookair/Projects \\
        MyMVCProject \\
        python3.10 \\
        2.1.0 \\
        --name_database restdb

This command will create a project with an MVC template by default.
The project will also create a virtual environment with Python 3.10,
Kivy version 2.1.0, KivyMD master version and a wrapper for working with
the database restdb.io.

.. image:: https://github.com/HeaTTheatR/KivyMD-data/raw/master/gallery/kivymddoc/mvc-database.png
    :align: center

.. code-block:: python

    class DataBase:
        def __init__(self):
            database_url = "https://restdbio-5498.restdb.io"
            api_key = "7ce258d66f919d3a891d1166558765f0b4dbd"

.. note::
    Please note that `database.py` the shell in the `DataBase` class uses the
    `database_url` and `api_key` parameters on the test database (works only in read mode),
    so you should use your data for the database.

Create project with hot reload
------------------------------

Template command::

    python -m kivymd.tools.patterns.create_project \\
        name_pattern \\
        path_to_project \\
        name_project \\
        python_version \\
        kivy_version \\
        --use_hotreload

Example command::

    python -m kivymd.tools.patterns.create_project \\
        MVC \\
        /Users/macbookair/Projects \\
        MyMVCProject \\
        python3.10 \\
        2.1.0 \\
        --use_hotreload yes

After creating the project, open the file `main.py`, there is a lot of useful
information. Also, the necessary information is in other modules of the project
in the form of comments. So do not forget to look at the source files of the
created project.

Others command line arguments
======================

Required Arguments
------------------

- pattern
    - the name of the pattern with which the project will be created

- directory
    - directory in which the project will be created

- name
    - project name

- python_version
    - the version of Python (specify as `python3.9` or `python3.8`) with
    - which the virtual environment will be created

- kivy_version
    - version of Kivy (specify as `2.1.0` or `master`) that will be used in the project

Optional arguments
------------------

- name_screen
    - the name of the class which be used when creating the project pattern

- name_database
    - provides a basic template for working with the 'firebase' library
    - or a complete implementation for working with a database 'restdb.io'

- use_hotreload
    - creates a hot reload entry point to the application

-use_localization
    - creates application localization files

.. warning:: On Windows, hot reloading of Python files may not work.
    But, for example, there is no such problem in macOS. If you fix this,
    please report it to the KivyMD community.
