Using switch() case in Lua!

[albino]

I wanted to use a switch() case: in one of my script and I couldn't find anywhere how to use it in lua.

After some research, I managed to get it working and I would like to share this in case someone looks for it.

function switch(n, ...)

	for _,v in ipairs {...} do

		if v[1] == n or v[1] == nil then

			return v[2]()

		end

	end

end



function case(n,f)

	return {n,f}

end



function default(f)

	return {nil,f}

end



switch(var,

	case(1,

		--do something

	end),



	case(2,

		--do something

	end),



	default(

		--do something

	end)

)

Can you show what shoud looks case that will:

when pressed ctr+1 (or 1) connect('z','z','z')
when pressed ctr+2 (or 2) connect('y','y','y')

etc?

For that case it's better if you use the built-in hotkey feature:
