rbxts-transformer-switchcase

!npm version !npm license 

Converts switch cases into simple if else blocks, to make it faster and to make it more legible.

Example

Input typescript

``ts
let a = 2

switch (a) {
case 1:
print("one");
break;

case 2:
print("two");
break;

default:
print("uhh what??");
break;
}
`






Output luau without the transformer

`lua
local a = 2
repeat
if a == 1 then
print("one")
break
end
if a == 2 then
print("two")
break
end
print("uhh what??")
break
until true
`






Output luau with the transformer

`lua
local a = 2
-- switch
if a == 1 then
print("one")
-- break
elseif a == 2 then
print("two")
-- break
else
print("uhh what??")
-- break
end
`
