A way to write switch-case statements in lua.
print "Hello, switch"
-- If the default case does not have to be handled, we can use the following auxiliary function:
local function switch(value)
-- Handing `cases` to the returned function allows the `switch()` function to be used with a syntax closer to c code (see the example below).
-- This is because lua allows the parentheses around a table type argument to be omitted if it is the only argument.
return function(cases)
-- The default case is achieved through the metatable mechanism of lua tables (the `__index` operation).
setmetatable(cases, cases)

Think twice about Wayland. It breaks everything!

Think twice before abandoning Xorg. Wayland breaks everything!

Hence, if you are interested in existing applications to "just work" without the need for adjustments, then you may be better off avoiding Wayland.

Wayland solves no issues I have but breaks almost everything I need. Even the most basic, most simple things (like xkill) - in this case with no obvious replacement. And usually it stays broken, because the Wayland folks mostly seem to care about Automotive, Gnome, maybe KDE - and alienating everyone else (e.g., people using just an X11 window manager or something like GNUstep) in the process.

The Wayland project seems to operate like they were starting a greenfield project, whereas at the same time they try to position Wayland as "the X11 successor", which would clearly require a lot of thought about not breaking, or at least providing a smooth upgrade path for, existing software.

In fact, it is merely an incompatible alternative, and not e
