========================
 OpenSlides Development
========================

Check requirements
''''''''''''''''''

- ``docker``
- ``docker-compose``
- ``git``
- ``make``

**Note about migrating from development setups before version 3.4**: You must set the
``OPENSLIDES_USER_DATA_DIR`` variable in your ``server/personal_data/var/settings.py``
to  ``'/app/personal_data/var'``. Another way is to just delete this file. It is
recreated with the right paths afterwards.


Get OpenSlides source code
''''''''''''''''''''''''''

Clone current master version from `OpenSlides GitHub repository
<https://github.com/OpenSlides/OpenSlides/>`_::

    git clone https://github.com/OpenSlides/OpenSlides.git --recurse-submodules
    cd OpenSlides

When updating the repository, submodules must be updated explicitly, too::

    git submodule update

Start the development setup
'''''''''''''''''''''''''''

Use `make` to start the setup::

    make run-dev

All your data (database, config, mediafiles) is stored in ``server/personal_data/var``.
To stop the setup press Ctrl+C. To clean up the docker containers run::

    make stop-dev

Running the test cases
''''''''''''''''''''''

For all services in submodules check out the documentation there.


Server tests and scripts
------------------------

You need to have python (>=3.8) and python-venv installed. Change your workdirectory to the server::

    cd server

Setup an python virtual environment. If you have already done it, you can skip this step::

    python3 -m venv .venv
    source .venv/bin/activate
    pip install -U -r requirements.txt

Make sure you are using the correct python version (e.g. try with explicit minor version: ``python3.8``). Activate it::

    source .venv/bin/activate

To deactivate it type ``deactivate``. Running all tests and linters::

    black openslides/ tests/
    flake8 openslides/ tests/
    mypy openslides/ tests/
    isort -rc openslides/ tests/
    pytest tests/

Client tests
------------

You need `node` and `npm` installed. Change to the client's directory. For the first time, install all dependencies::

    cd client/
    npm install

Run client tests::

    npm test

Fix the code format and lint it with::

    npm run cleanup

To extract translations run::

    npm run extract
