Can’t read Anki source unless your work is GPL. Could you share the insights yourself?

My work is MIT, as is ts-fsrs. I said anki source code, but I was being hyperbolic. To understand the different exports of ts-fsrs I had to browse around in different repos at https://github.com/open-spaced-repetition https://github.com/open-spaced-repetition (particularly rs-fsrs; which I think is used in Anki proper) as well as read the algorithm https://github.com/open-spaced-repetition/fsrs4anki/wiki/The-Algorithm https://github.com/open-spaced-repetition/fsrs4anki/wiki/The... and infer by names being used. I complain here, but this is open source and if I was slightly more ambitious I would submit PR with the missing docs (or at least an issue). PS. my work is here https://github.com/runarberg/shodoku https://github.com/runarberg/shodoku in case you are interested, but the source code bears the mark of being a weekend hobby project, so read at own risk ;)

  Thanks for sharing details I'd like to port my own flashcards app, Manabi from SM2 to FSRS so this is helpful I made this companion reader app as well, btw, for learning Japanese: https://reader.manabi.io https://reader.manabi.io

    Nice. I jumped straight to FSRS so I can’t compare, but so far I have no regrets. One of my features is I progressively disappear the furigana in the included dictionary and example sentences, as the reading proficiency of the kanji increases (specifically at 99% retrievability) https://github.com/runarberg/shodoku/blob/main/src/helpers/fsrs.ts#L93-L95 https://github.com/runarberg/shodoku/blob/main/src/helpers/f... This feature was very easy to implement as retrievability is inherent in the algorithm (maybe it is in SM2 as well; I don’t know; but it was trivial in FSRS). This library also makes it easy to undo a review (one of my missing features) as long as you keep the review records (which this library also makes easy).

      Very nice to have these modern setups under freer open source licenses. I have all my data synced to the client to work offline, so it's very nice having FSRS available on iOS & elsewhere (+ ability to run the rust one)

        I thought I recognized your username from a political debate here a few months ago. I figured you would enjoy the donations page of my app: https://shodoku.app/about#donations https://shodoku.app/about#donations > If you insist on paying for this app, consider donating to UNWRA instead. Glad to see solidarity among the Japanese learning community.

Not all of Anki's source code is GPL. The FSRS implementation used within Anki is BSD, for example.

  I know, my message is about referencing FSRS usage rather than its implementation
