Hi all,
Interestingly, I & @fcard haven't really had time to make powscript compatible with bash v5.
My main usecase for powscript is regenerating some powscripts once in a while (but not often), so the project is sort of in maintenance-mode instead of feature-development.
If there's anyone who'd like to take a stab at a bash v5 conversion, or a different parser-frontend (AWK/LUA) feel welcome to do a PR.
