Module: Lexdrill::Stats

Defined in:
lib/lexdrill/stats.rb

Overview

Tracks how many times each word/phrase has been shown by next, persisted as a word => count JSON object at .drill.stats (same base path as .drill.txt/.drill.counter). Every BUCKET_SIZE shows moves a word into the next display-color bucket (see Lexdrill::Colorizer); once a word reaches GRADUATION_THRESHOLD shows it's considered mastered and next stops selecting it.
