This personal Lua-based script automates various actions based on mouse button presses and simple swipe gestures. It was originally written for use with Logitech Gaming Software (short: LGS), and later adopted for its successor replacement, Logitech G HUB.
Unfortunately Logitech broke Lua scripting support for its G HUB app during a Q4 2020 update, no longer including various standard Lua libraries this script depends upon. Although most of those missing standard libraries were re-added in a later patch, as of March 2021 some core features and standard library functions are still missing, including Lua's variable arguments and related unpack function. Despite some polyfilling attempts, as an unfortunate consequence this script is broken in those versions of G HUB. However, it remains functional in LGS and in G HUB prior to version 2020.12.
In an attempt to preserve these custom button and gesture actions, a standalone and more configurable Go-based alternative, Mouser, was created.
