Hi,I'm very interested in this project, but it seems a long time no update, I wanna know if it continues？

Yes, the project is still alive, but as the primary contributor, since I've been busy (and probably will be for another month), I haven't had time to push out the release that I had planned to. I will; In the meantime, I'm hoping @kblief will be raising a PR for this particular issue soon ;)
