trane

Why we included this project

Trane is a Rust library that schedules practice for complex, hierarchical skills. Instead of a fixed curriculum, it models a skill as a dependency graph and uses spaced repetition plus mastery-based logic to decide what to drill next, based on how you rate your own performance on each exercise. Course content is plain text, so you can write your own materials or combine courses other people have published. That flexibility is why it appeals to developers building domain-specific tutors; the author's own literacy app runs on top of it. If you need the scheduling and mastery-tracking logic handled for you rather than building a flashcard tool from scratch, this is a solid foundation.
