This Linux module creates virtual video devices. V4L2 applications will treat these as ordinary video devices but read video data generated by another application, instead of a hardware device such as a capture card.

This lets you apply nifty effects to your Jitsi video, for example, but also allows some more serious things like adding streaming capabilities to an application by hooking GStreamer into the loopback device.

This package provides library of glib utilities.

Package uinput is a pure go package that provides access to the userland input device driver uinput on linux systems. Virtual keyboard devices as well as virtual mouse input devices may be created using this package. The keycodes and other event definitions, that are available and can be used to trigger input events, are part of this package ("Key1" for number 1, for example).

This package provides Command-line option parsing for Go.

Dotool reads actions from stdin and simulates keyboard/mouse input using Linux's uinput module. It works systemwide and supports keyboard layouts.

This package provides a universal zig executable that lets you run any version of zig. Since you can only have one zig executable in your PATH, anyzig removes the limitation that this can only be one version. The version of zig to invoke is pulled from the minimum_zig_version field of build.zig.zon. build.zig.zon is found by searching the current or any parent directory.
