-- 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). | |
