LUMUI Browser

Reference browsers for LUMUI.

This repository contains standalone browser and renderer implementations for the LUMUI specification. Each implementation demonstrates one possible presentation of the same semantic application model. No implementation is canonical or more important than another.

C# with Avalonia	C# with Terminal.Gui
Native desktop controls, window management and graphical developer tools.	Keyboard-first terminal controls, dialogs, menus and terminal media presentation.
Open the Avalonia implementation	Open the Terminal.Gui implementation

Both current implementations support navigation, tabs, history, bookmarks, downloads, credential storage, accessibility preferences, developer inspection and semantic component rendering. They request validated LUMUI documents directly and do not embed an HTML browser engine.

Future implementations can be added beside CSharp in their own language or platform directory. Examples may use Python, WPF, mobile frameworks, kiosk toolkits or other suitable technologies.

Build and run

The current C# implementations require Windows and the .NET 10 SDK. Each solution can be restored, built and run independently.

Avalonia

cd Source
dotnet restore CSharp/Avalonia/Lumui.Avalonia.sln
dotnet run --project CSharp/Avalonia/Lumui.Browser -- https://lumuiopensource.com/

Terminal.Gui

cd Source
dotnet restore CSharp/TerminalGui/Lumui.TerminalGui.sln
dotnet run --project CSharp/TerminalGui/Lumui.Cli -- https://lumuiopensource.com/

Native AOT publishing

cd Source
dotnet publish CSharp/Avalonia/Lumui.Browser/Lumui.Browser.csproj -p:PublishProfile=win-x64-aot
dotnet publish CSharp/TerminalGui/Lumui.Cli/Lumui.Cli.csproj -p:PublishProfile=win-x64-aot

The Avalonia and Terminal.Gui executable projects enable Native AOT, trimming analysis and generated JSON metadata.

Specification resources

A versioned snapshot of the normative LUMUI resources, including the component specification, is included for deterministic builds. The canonical resources are maintained in the LUMUI repository.
