Ace编辑。 将当前编辑状态设置为基础

Question

I'm using ace editor wrapped by react-ace for my project.

How can I destroy all undo/redo history in certain moment when I need it?

I've tried this.aceRef.editor.destroy(); (just react ref bound with editor), but unfortunately it doesn't play well in some circumstances. So, I just need to clean undo/redo session/history or something like that.

Any solution?

Ace editor actually has this reset method with UndoManager .

Then you need to assign temporary stored undomanager as base.

It could be done smth like that:

const { editor } = this.aceRef;
const session = editor.getSession();
const undoManager = session.getUndoManager();
undoManager.reset();
session.setUndoManager(undoManager);
