Understanding Spectre.Console's Rendering Model

An in-depth explanation of how Spectre.Console renders text and widgets to the terminal. This article discusses the console Capabilities detection (how it checks for ANSI support, Unicode capability, terminal type, etc.) and how that influences rendering. It explains concepts like measuring content width and auto-adjusting to console window size, and how Spectre.Console avoids flicker by rendering off-screen (if applicable) then updating. It also covers how IRenderable objects work – describing that most widgets implement IRenderable and the console simply calls their render logic. This section might also touch on performance considerations and how updating works (e.g. the render loop for live widgets). It gives readers a mental model of what happens when they call AnsiConsole.Write or update a live widget, enhancing their understanding of the library's internals.
