listening-text-view-events

Listen to text view events by implementing ITextViewOpenClosedListener or ITextViewChangedListener using MEF-based listeners, enabling extensions to react to editor open, close, and content changes across Visual Studio extensibility models.

Track live text changes by implementing ITextViewChangedListener to react to content modifications within an editor, allowing extensions to trigger live analysis or apply decorations during active editing sessions.

Text view listeners support the out-of-process VisualStudio.Extensibility model, alongside the in-process VSIX Community Toolkit and MEF-based VSSDK, enabling consistent per-editor lifecycle event handling across different extension architectures.

Initialize per-editor state by registering a text view listener to handle editor open events, allowing extensions to set up per-document resources and UI integration immediately when a text view is created.

Extensions leak memory when editor lifecycle listeners lack proper filtering and cleanup. Implementing correct disposal for per-editor state when handling close events prevents resource leaks in Visual Studio extensions.

Handle editor lifecycle events by implementing MEF-based text view listeners with proper filtering and cleanup, providing a unified approach for per-editor initialization and live-change tracking across out-of-process, in-process, and legacy VSSDK models.
