Terminal.Gui.Text

Terminal-native text-editing stack for Terminal.Gui, built on a hard fork of AvaloniaEdit's pure-data layers (Document, Folding, Search, Indentation, Highlighting).

Two NuGet packages:

• Terminal.Gui.Text — UI-framework-independent document model: rope-backed TextDocument, TextAnchor, UndoStack, FoldingManager, search, indentation, highlighting. No Terminal.Gui dependency; reusable from other front-ends.
• Terminal.Gui.Editor — a View subclass (Editor) consuming Terminal.Gui.Text and rendering on a cell grid, with multi-caret, folding, search, and (post-MVP) TextMate highlighting.

Editor ships alongside TextView. It is not a drop-in replacement and has no source-compat obligation to it.

Status

Pre-alpha. Repo bootstrap only — see specs/00-plan.md for the full implementation plan, phased milestones, and open decisions.
