Variable onDidOpenTextDocumentConst

An event that is emitted when a text document is opened or when the language id of a text document has been changed.

To add an event listener when a visible text document is opened, use the TextEditor events in the window namespace. Note that:

• The event is emitted before the document is updated in the active text editor
• When a text document is already open (e.g.: open in another visible text editor) this event is not emitted
