No, it is a nasty mess of shell scripts and Haskell, though mostly Haskell now. (There used to be XML for recipes, what a mess.) It is useless to others without documentation, which would take a long time to write. Maybe one day. It makes grocery lists with items in categories, which saves me so much time that I have been using it every week for years. But if someone made something decent I would happily pay for it.

Would you mind uploading it somewhere nonetheless? Just your design and flow should be a good read (from source).

Heh, that sounds like a very neat system. The category for shopping especially so.
