SVML interpreter link → Sinter link → Slink → Sling.
A sling is also something used to launch small objects... so, we use a sling to launch small programs to devices.
This repository contains an MQTT-based protocol that allows compiled SVML programs to be sent to devices to run, plus daemons that implement the protocol for various platforms.
The initial use case is for Source Academy users to be able to write Source programs in the Source Academy frontend and seamlessly run those programs on embedded devices, but ultimately the daemons just receive a compiled binary and pass it to a runtime, so this can be used for anything, really.
Note that because the protocol merely specifies the MQTT topics that devices will receive programs from and publish output to, there is little code shared between the daemons (aside from Sinter itself), which use their respective platforms' MQTT and TLS libraries where possible.
See Sling.md for the protocol.
