I haven't worked on in a long time, the parser I designed is pretty much unknown to me at this moment to dive right away. So been procrastinating on it on whether or not restart the work again. Feel free to make any changes and work on it by yourself. I hope to find the strength and motivation to work on it soon. Thanks.
