The code below runs just fine on both of these online Lua websites.
local tab = {}
tab[938388893] = "hi"
tab[987383332] = "Hello"
for k,v in pairs(tab) do
print(k)
print (v)
end
But when I try it using the Sol2 library (embedded in C++) it eats all my memory.
It seems to create a giant table with the array part full of mostly empty values and just those two strings in their corresponding array slots.
Is it a Sol2 issue or a C Lua binding issue? Anybody know?
I’d say probably Sol. It’s a matter of modelling the data. I’ve seen the same issue with JSON encoders that check a table for integer-only keys, and then assume the thing is to be encoded as an array. This obviously ends up as one massive JSON
blob.
I don’t know Sol, but maybe add a dummy-key (non-integer) to the table, to force it to not encode as an array?
