Expand description
Cocoon → Mountain window.setTextEditorDecorations notification.
Fired whenever an extension calls editor.setDecorations(decorationType, rangesOrOptions). Mountain forwards the payload as
sky://decoration/set-ranges so Sky’s ICodeEditorService can apply the
ranges to the Monaco editor for the matching URI.
Payload shape (from Cocoon Window/Namespace.ts):
{
"decorationTypeKey": "GitLens.blame",
"uri": "file:///path/to/file.ts",
"rangesOrOptions": [
{ "range": { "startLineNumber": 1, "startColumn": 1, "endLineNumber": 1, "endColumn": 80 } }
]
}Channel-drain batching: ~5-200 calls per extension per second during scroll; one Tauri event per frame (16 ms window, drain stragglers).
