MCP server de Bhasini Indic Languages

Bhasini (भाषिणी)

A multilingual Indic typing editor for all 22 scheduled languages of India, built with Blazor WebAssembly. Everything runs in the browser; no server round-trips while you type.

It grew out of the Kannada Nudi web editor (KannadaNudiEditor/KannadaNudiWeb) and keeps its shape: a Quill rich-text editor whose keystrokes are transliterated by a C# engine.

Features

• Phonetic typing: type how it sounds (namaste → नमस्ते, vaNakkam → வணக்கம், aadaab → آداب). ITRANS/Baraha-style keys: capitals for retroflex/long sounds (T D N L Sh A I U E O), M anusvara, H visarga, .h explicit virama, _ to stop letters joining, | / || danda.
• InScript: the government-standard layout for every Brahmic script.
• F9 switches between the selected language and English.
• Key map panel for the current language and method. Tap a letter to insert it, which also helps on phones.
• Native digits toggle (१२३, ௧௨௩, ۱۲۳, …).
• Convert: rewrite text from one Indian script to another, or turn romanised text into script.
• Dictation through the browser's speech recognition (Chrome and Edge, where the locale is supported).
• Open .txt / .docx, save as .docx, .txt or .html. Settings are remembered per browser.

How it works

src/Bhasini.Core has no web dependencies:

• Input/BrahmicPhoneticEngine turns Latin keys into Devanagari, with a per-language PhoneticProfile (Dravidian short e/o, word-final virama, Tamil nasals, local key conventions).
• Scripts/OffsetScriptMapper maps Devanagari into each ISCII-derived Unicode block by offset. Letters a script lacks fall back to the nearest letter. Script-specific spelling rules (Malayalam chillus, Gurmukhi tippi/addak, Bengali য়) run as post-processing.
• Scripts/MeeteiMayekMapper handles Meetei Mayek. Input/SequenceEngine handles the alphabetic scripts (Perso-Arabic with word-initial/final forms, and Ol Chiki).
• Input/TypingSession keeps the Latin keys of the current word and re-renders the whole word on every key, returning a minimal { delete, insert } edit for the editor.

src/Bhasini.Web is the Blazor WebAssembly app. wwwroot/js/editor.js intercepts keys in Quill and calls the session synchronously.

Run

Requires the .NET 8 SDK.

dotnet run --project src/Bhasini.Web

dotnet test

Docker (nginx serving the published static files on port 5000):

docker build -t bhasini .

Script fonts come from Google Fonts (Noto). When offline, the editor falls back to system fonts such as Nirmala UI on Windows.
