How to detect keystrokes in Swift on Linux?

Question

I am writing a command line application in Swift that will run on Linux. I want to know what keys the user is touching in real time so I can show a value associated with each key.

Is there aa non blocking way of capturing user keystroke events in real time one key at a time?

I know of the readLine() function but that captures whole words and is blocking.

Anybody knows of a working solution?

Answer 1

If you know which input device (for example a USB keyboard) you want to read the real time keystrokes from, then you could use something like: https://github.com/Dev1an/InputEvents

It does not use standard command line input streams but reads the events directly from /dev/input/... devices instead.
