< p > Back up a dirty custom document.< / p >
< / div >
< p > Backups are used for hot exit and to prevent data loss. Your < code > backup< / code > method should persist the resource in
its current state, i.e. with the edits applied. Most commonly this means saving the resource to disk in
the < code > ExtensionContext.storagePath< / code > . When the editor reloads and your custom editor is opened for a resource,
your extension should first check to see if any backups exist for the resource. If there is a backup, your
extension should load the file contents from there instead of from the resource in the workspace.< / p >
< p > < code > backup< / code > is triggered approximately one second after the user stops editing the document. If the user
rapidly edits the document, < code > backup< / code > will not be invoked until the editing stops.< / p >
< p > < code > backup< / code > is not invoked when < code > auto save< / code > is enabled (since auto save already persists the resource).< / p >

< p > Token that signals the current backup since a new backup is coming in. It is up to your
extension to decided how to respond to cancellation. If for example your extension is backing up a large file
in an operation that takes time to complete, your extension may decide to finish the ongoing backup rather
than cancelling it to ensure that the editor has some valid backup.< / p >

< p > Signal that an edit has occurred inside a custom editor.< / p >
< / div >
< p > This event must be fired by your extension whenever an edit happens in a custom editor. An edit can be
anything from changing some text, to cropping an image, to reordering a list. Your extension is free to
define what an edit is and what data is stored on each edit.< / p >
< p > Firing < code > onDidChange< / code > causes the editors to be marked as being dirty. This is cleared when the user either
saves or reverts the file.< / p >
< p > Editors that support undo/redo must fire a < code > CustomDocumentEditEvent< / code > whenever an edit happens. This allows
users to undo and redo the edit using the editor' s standard keyboard shortcuts. The editor will also mark
the editor as no longer being dirty if the user undoes all edits to the last saved state.< / p >
< p > Editors that support editing but cannot use the editor' s standard undo/redo mechanism must fire a < code > CustomDocumentContentChangeEvent< / code > .
The only way for a user to clear the dirty state of an editor that does not support undo/redo is to either
< code > save< / code > or < code > revert< / code > the file.< / p >
< p > An editor should only ever fire < code > CustomDocumentEditEvent< / code > events, or only ever fire < code > CustomDocumentContentChangeEvent< / code > events.< / p >
