Kivy Hotreload

Kaki - Advanced application library for Kivy

This library enhance Kivy frameworks with opiniated features such as:

• Auto reloading kv or py (watchdog required, limited to some uses cases)
• Idle detection support
• Foreground lock (windows only)

Installation

pip install kaki-cli

Example

This is a bootstrap that will:

• automatically declare the module live.ui (live/ui.py) as a provider for the widget UI
• build the application widget, and show it to a window

If the bootstrap is started with the environment variable DEBUG=1, it will start a watchdog, and listen for changes, according to AUTORELOADER_PATHS. When something changes, the current application widget will be cleared out, and a new one will be instanciated, after reloading.

kaki run # deploy app and run hotreload
kaki run --build # build, deploy and run hotreload

Idle Management

The idle detection feature is designed to trigger an action if the user has not touched the screen for a certain period of time. This can be used to display an attractor screen, screensaver, or other content.

To enable idle detection, set the IDLE_DETECTION configuration to True. Kaki will then listen for touch down/move events. If no such events occur within the IDLE_TIMEOUT interval, or if the rearm_idle function has not been called, the on_idle event will be triggered on the application class. If a touch event occurs or rearm_idle is called while the system is in idle mode, the on_wakeup event will be triggered on the application class.

If you are playing a video and do not want idle detection to be triggered, you can use the rearm_idle function on the application class to reset the idle timer to 0 seconds.
