getconstants

Returns constants from a Lua function or stack level as a table keyed by one-based constant index. target must be a function or stack level number. Invalid stack levels raise “Level out of range”. Non-function and non-number targets raise a type error expecting “function or number”. C closures raise “Lua function expected”. Nil, function, and table constants are absent from the returned table. debug.getconstants is an alias.

getconstants(target: function | number): table

Alias

debug.getconstants

Argumen

function | number

Table keyed by one-based constant indices. Indices for nil, function, and table constants are absent.

Contoh

Read the Proto constants table for a Lua closure.

local function target()

for index, value in pairs(constants) do
    print(index, value)
