What dose recfield stand for?
Or what is the meaning of 'rec'?
static void recfield (LexState *ls, struct ConsControl *cc) {
/* recfield -> (NAME | `['exp1`]') = exp1 */
FuncState *fs = ls->fs;
int reg = ls->fs->freereg;
expdesc key, val;
if (ls->t.token == TK_NAME) {
luaY_checklimit(fs, cc->nh, MAX_INT, "items in a constructor");
checkname(ls, &key);
}
else /* ls->t.token == '[' */
yindex(ls, &key);
cc->nh++;
checknext(ls, '=');
luaK_exp2RK(fs, &key);
expr(ls, &val);
luaK_codeABC(fs, OP_SETTABLE, cc->t->u.s.info, luaK_exp2RK(fs, &key),
luaK_exp2RK(fs, &val));
fs->freereg = reg; /* free registers */
}
