Namespace Terminal.Gui.Editor.Document.Folding
Code-folding infrastructure for collapsing and expanding regions of a document.
Contains FoldingManager (manages fold state), FoldingSection (a single collapsible region), IFoldingStrategy (pluggable strategy interface), and built-in strategies (BraceFoldingStrategy, XmlFoldingStrategy).
Foldings auto-expand when the caret moves inside them. Consumers can implement custom IFoldingStrategy instances for language-specific folding rules.
