> Given a function that returns multiple values, is there a way to construct a table, but where each value is assigned a name rather than an index
You'll need a helper function:
function namedtable(name,...)
local t=table.pack(...)
local n=t.n
t.n=nil
for i=1,n do
local v=t[i]
t[i]=nil
t[name[i] or 0]=v
end
return t
end
function f()
return 100,200,400
end
local t=namedtable({"day", "month", "year"},f())
for k,v in pairs(t) do print(k,v) end
