Avalonia-first terminal UI

`RoyalApps.RoyalTerminal.Avalonia` provides a backend-neutral `TerminalControl` with theming, virtualization, regex text highlighting, framebuffer shaders, capture/replay, snapshot export, and rich input handling.

Multi-transport runtime

PTY, pipe, SSH, raw TCP, Telnet, and serial transports share a single session model and option surface.

Product workflow state

`RoyalApps.RoyalTerminal.Terminal` includes versioned workspace, pane, shell-integration, command-history, and suggestion contracts so hosts can restore sessions without mixing workflow state into terminal emulation.

Managed and native VT engines

Choose the managed `BasicVtProcessor`, the native Ghostty-backed processor, or the default factory with deterministic fallback behavior.

Modular rendering stack

Use the Skia cell renderer and shader post-process pipeline alone or add Ghostty renderer interop packages and native assets where they fit your host architecture.

Production validation surface

The repository includes an Avalonia demo, a control catalog, headless/UI tests, integration tests, native packaging checks, and benchmarks.

Repository-scale documentation

This guide covers the source tree outside the `external/ghostty` submodule with feature-led articles plus generated API reference pages for the public managed packages.

Embedding

Avalonia host workflows

Wire the control, configure sessions, preserve history, and export terminal state.

Reusable UI APIs

Build on the packaged shell

Use the ready-made shell, native menu helpers, settings panel, and pane composition APIs from your own app.

Runtime

Terminal behavior

Review transports, screen state, highlighting, Ghostty interop, and native compatibility notes.

Rendering

Text, graphics, and shaders

Understand the rendering stack and shader compatibility across Skia, Ghostty, and Windows Terminal models.

Operations

Ship and troubleshoot

Use sample tooling, validate release workflows, and diagnose common integration issues.
