🤝 Contributing

You need to have Poetry installed on your machine.

To install poetry in Raspbian you need to follow these instructions to install rust compiler, this is temporary until this issue is resolved:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
sudo apt-get install pkg-config libssl-dev
curl -sSL https://install.python-poetry.org | python3 -

After having poetry, to install the required dependencies, run the following command:

poetry install --with dev

Also be aware of this issue and until it is resolved you can manually disable keyring by prefixing your poetry commands like this:

PYTHON_KEYRING_BACKEND=keyring.backends.null.Keyring poetry install

You can run linter over whole codebase by running this command:

poetry run poe lint

Subscriptions

The subscriptions are divided into three groups:

• Screen subscriptions are those assigned to a particular stack item, but their handlers doesn't change anything in the StackItem itself. The handler just changes something on the rendered screen and if that stack item is not visible, the handler doesn't need to be called. Therefore these subscriptions are cleared when the current screen is changed. Samples:
  • items of the currently visible menu
  • title of the currently visible screen
• Menu subscriptions are those assigned to a particular menu. Like screen subscriptions, they are cleared when the current screen is changed. They also get cleared when the menu is scrolled. Samples:
  • heading of a headed menu
  • sub_heading of a headed menu
  • placeholder of a menu
• Stack item subscriptions are those assigned to a particular stack item. They are cleared when the stack item is popped. They stay alive as long as the stack item is in the stack, even if it is in the background. In other words, unlike the other two, they are not cleared when, for example, a sub-menu or an application is opened on top of the current stack item. Samples:
  • menu of an item
