Unable to perform Undo function in monaco editor

Currently in my Angular 7 project, I have integrated the Monaco editor for coding purposes. One issue I am facing is that when I make a change to the code and then press ctrl+z to undo it, the previous code is successfully restored. However, if I change the coding language and then try to undo a recent change by pressing ctrl+z, the previous code does not get restored. This means that after changing the coding language, the ability to restore the previous code using ctrl+z is lost.

I would appreciate any help or suggestions to resolve this issue. Thank you.

Answer №1

Utilize the function executeEdits to implement changes while preserving the undo stack:

const newText = 'the updated text';

// Selecting all the existing text
const entireTextRange = editor.getModel().getFullModelRange();

// Applying the new text over the selected range
editor.executeEdits(null, [{
  text: newText,
  range: entireTextRange
}]);

// Indicates that the previous edit is a complete undo/redo operation.
editor.pushUndoStop();
