Medumba ios/android keyboard # Clavier Medʉmba — Keyman keyboard for Medumba (byv) A cross-platform keyboard for typing **Medumba** (a Bamileke / Eastern Grassfields language of Cameroon, ISO 639-3 `byv`) on **iOS, Android, Windows, macOS, Linux, and the web** — built once with Keyman. - **Special letters** on a dedicated top row: `ɛ ɔ ə ʉ ɨ ŋ ɲ ɣ ʃ ʒ ʼ` - **Tones by long-press**: hold a vowel → pick high / low / mid / falling / rising - **Correct Unicode**: every toned vowel is emitted as *base + combining mark* (NFD), because `ʉ ɛ ɔ ə ɨ` have no precomposed accented forms - **Digraphs need no keys**: `mb, ts, ŋg, pf, kw…` are just typed in sequence --- ## ⚠️ The one thing to verify: which tones are written This is the only linguistically-sensitive decision in the project. The current build offers **5 tones** (high `◌́`, low `◌̀`, **mid `◌̄`**, falling `◌̂`, rising `◌̌`). Many AGLC-based orthographies **leave the mid tone unmarked** and write only high / low / contours. **Confirm the Medumba convention with the official syllabaire / the Comité de langue medumba.** If mid is not written, drop it: 1. Open `tools/generate-layout.mjs` 2. Delete the `moyen` line from the `TONES` array 3. Re-run `node tools/generate-layout.mjs` That's the whole change — the layout regenerates. --- ## Project layout ``` medumba-keyboard/ ├─ medumba.kpj Keyman Developer project (v2.0) ├─ source/ │ ├─ medumba.kmn keyboard source (desktop rules + metadata) │ ├─ medumba.keyman-touch-layout GENERATED — the iOS/Android on-screen layout │ ├─ medumba.kps package definition (→ .kmp installer) │ └─ welcome.htm shown to users on install ├─ tools/ │ └─ generate-layout.mjs builds the touch layout from data tables └─ build/ compiler output (git-ignored) ``` Do not hand-edit `source/medumba.keyman-touch-layout` — edit the generator and re-run it. --- ## Build it **Prerequisites:** Keyman …
