Bookshelf micro-module that shows random vocabulary words
Been using KOReader's Vocabulary Builder for a while to save words I look up while reading, but I kept forgetting to actually review them. So I made a little micro-module for Bookshelf that puts a random word with its dictionary definition right on the home screen.
It reads from your Vocabulary Builder SQLite db, looks up each word via sdcv (StarDict), and shows:
- The word (big, bold)
- Word type (noun, verb, etc.)
- 1-3 definitions
Tap to get a different word. Long-press to tweak how many definitions to show, toggle the word type, or adjust font size.
Performance-wise, it only calls sdcv once per session — all uncached words are batched into a single command at module start. Definitions are cached to a JSON file, so taps are instant and there's no risk of OOM from forking sdcv multiple times.
It's in early development — tested on the emulator and my Kobo Elipsa 2E with a Spanish dictionary. YMMV with other languages/dictionaries, but it should work with any StarDict dictionary you have installed.
Everything (code, docs, architecture) was generated by AI agents under my direction.Kind of a fun experiment in human-AI collaboration for a practical e-reader tool.

Curious if anyone else finds this useful and happy to take suggestions.
