First, we go through every environment variable key and record all cases where there are reference to other variables / dependencies. We track two sets of variables - resolved and yet-to-be-resolved. We pass over a list of variables over and over again and when all variable's dependencies were resolved during previous passes we perform a replacement for that variable, too. Over time the size of `toResolve` set should go down to zero, however circular dependencies may prevent that. We track the size of `toResolve` between iterations to avoid infinite looping. At the end we produce an object of the same size and shape as the original, but with the values replace with resolved versions. |
