- Create stores for vowels, consonants, and matras using Unicode codepoints.
- Define base layer mapping for English characters to themselves.
- Define AltGr layer rules mapping Latin phonetics to Devanagari characters (e.g., “k” -> क, “kh” -> ख, “aa” -> आ).
- Add touch layout with long-press popups for vowel signs and special conjuncts.
- Test in desktop and mobile simulators; adjust mappings and long-press popups.
Resources and next steps
- Use Keyman Developer’s built-in keyboard templates to bootstrap.
- Read Keyman documentation for exact syntax, code examples, and platform-specific packaging steps.
- Gather community feedback early: share alpha builds with native speakers for correction and usability testing.
Building multilingual keyboards is a mix of linguistics, UX design, and careful engineering. Start small, iterate with native users, and expand features (predictive text, localized help) after core input behavior is solid.
