Create a table with table keys in Lua with the C API -

-

in lua, can create table keys tables:

t = {} t[{1,2}] = 2

i know how analogous thing using c api. is, writing c function callable lua, return table table keys. tried push table key , use lua_settable, seems nothing.

edit: relevant code:

lua_createtable(l, 0, n); for(i = 0; < n; ++i){     // push key table     lua_createtable(l, 2, 0);     for(j = 0; j < 2; ++j){         lua_pushinteger(l, j+1);         lua_pushinteger(l, j);         lua_settable(l, -3);     }     // push value table     lua_createtable(l, 4, 0);     for(j = 0; j < 4; ++j){         lua_pushinteger(l, j+1);         lua_pushnumber(l, j);         lua_settable(l, -3);     }     lua_settable(l, -3); }

edit: being dumb; used lua_objlen(l, -1) @ end check on size of table, returns 0 since there no integer keyed entries. also, in lua code processed table, used ipairs instead of pairs. silly mistake.

pushing table key , using lua_settable right thing do. likely, forgot push on value , did t = { {} = nil }, of course nothing.
