This module connects to the bootloader to send messages to the splash screen.
|
|
It is intended to act as a RPC interface for the functions provided by the bootloader, such as displaying text or
|
closing. This makes the users python program independent of how the communication with the bootloader is implemented,
|
since a consistent API is provided.
|
|
To connect to the bootloader, it connects to a local tcp socket whose port is passed through the environment variable
|
'_PYI_SPLASH_IPC'. The bootloader creates a server socket and accepts every connection request. Since the os-module,
|
which is needed to request the environment variable, is not available at boot time, the module does not establish the
|
connection until initialization.
|
|
The protocol by which the Python interpreter communicates with the bootloader is implemented in this module.
|
|
This module does not support reloads while the splash screen is displayed, i.e. it cannot be reloaded (such as by
|
importlib.reload), because the splash screen closes automatically when the connection to this instance of the module
|
is lost.

this function should handle it and avoid using the logger.

This will close the splash screen and renders this module unusable. After this function is called, no connection

can be opened to the splash screen again and all functions in this module become unusable.
