Accessing the queue status when using the Anki algorithm

[SiriusStarr]

Good catch! So there's not actually anything wrong with presenting Hard for a learning-stage card, it's just that it doesn't do anything different at that stage than answering Again. The behavior of bother "learning" and "lapsed" cards is identical, inasmuch as both Again and Hard reset the card to the first stage, whereas Good advances it and Easy instantly graduates it to review. Anki itself I believe only presents 3 buttons for those stages to avoid the false illusion of choice.

So in the short term, nothing wrong with leaving Hard as an option. However, I think it would be good moving forwards to reveal what stage a card is in, as one could imagine wanting to display this information to a user, and it would also allow changing the presentation of the answer buttons. One option would be to make getDueCardIndices return queue status as well, making its signature something like

type Queue
    = New
    | Learning
    | Reviewing
    | Lapsed

getDueCardIndices : Posix -> Deck a b -> List ( Int, Queue, Bool )

The downside to this is its a breaking change, necessitating a major version bump. Other downside is that it's simply more information that someone might not want to have.

Other option would be to keep getDueCardIndices the same and add a new function, like

type Queue
    = New
    | Learning
    | Reviewing
    | Lapsed

getDueCardIndices : Posix -> Deck a b -> List ( Int, Bool )

getDueCardIndicesAndQueue : Posix -> Deck a b -> List ( Int, Queue, Bool )

Which would allow one to choose which they wanted and would be a minor version.

I think having the possibility to adapt displayed information and controls to the state of the card would be nice indeed.A new getDueCardIndicesAndQueue function would be welcome!
Great work anyway!

Added in 7f71df9. See getDueCardIndicesWithDetails to get the detailed queue status and the like for all cards or getCardDetails for details on a single card.

Sorry turnaround was slow on that! Had a lot of demands on my time this past month.
