README

Amader Bangla Keyboard

A Windows input method to type Bangla phonetically (e.g. amar → আমার). After installation you switch your input to "Amader Bangla Keyboard" (Win+Space) and type romanized Bangla in any application.

Built as a TSF Text Input Processor (a native Windows input method) with a portable, unit-tested phonetic engine at its core.

Status

✅ Phase 1 — phonetic engine (engine/): longest-match tokenizer + stateful assembler (anusvara, ঋ, chandrabindu, visarga, digits); 16 tests pass.
✅ Phase 0 — TSF TIP skeleton (app/): registrable COM input method that links the engine into the keystroke path.
✅ Phase 3 — composition & commit (app/): live underlined preview, commit on space/enter, backspace editing. (Builds clean; live registration + in-app testing is the next step.)
✅ Phase 2 — standalone harness (harness/): console app to convert romanized Bangla without registering anything.
✅ Phase 4 — UX (started) (app/): language-bar button (বাং/Eng), Ctrl+Shift+B Bangla/English toggle (session-only; starts in Bangla).
✅ Phase 5 — installer (installer/, scripts\package.bat): builds x64+x86 and stages dist\ with self-elevating install/uninstall scripts.
✅ Typing guide: installed as a Start Menu shortcut ("Amader Bangla Keyboard Typing Guide") and in the language-bar menu — a full key-map cheat sheet.
✅ Word suggestions: a curated roman→Bangla dictionary (autocorrect-style) plus ~65k-word completion from the Google bn lexicon, frequency-ranked, with a candidate window that learns which words you pick (%LOCALAPPDATA%\BanglaPhonetic\learned.tsv). ↓/↑/Tab pick, Enter/Space commit, Esc dismiss.
✅ Coverage tested on a Prothom Alo article: 100% of characters typeable; 84% of distinct words have a suggestion.
✅ x64 + x86 + ARM64 binaries; architecture-aware installer.
⏳ Next: code signing.
