How can I keep undo history after saving on Visual

Question

I'm using latest version of VS code (1.9.0).

After I undo (ctrl+z) something, and save the file (ctrl+s), then I cannot redo anymore (ctrl+y).

I would like to go back and forth during the editor is running same as Sublime or other editor. Can anyone solve this problem? Thank you.

Answer 1

The problem is confirmed in microsoft/vscode issue 10932 "Undo stack lost" (and linked to the aforementioned issue 7169, as part of the undo/redo issues)

We loose the undo stack very easily when leaving a dirty file in a tab (not visible) and then saving the dirty file:

• open some tabs and make them dirty
• wait for a few seconds
• press "Save All"
• go to those tabs that where not visible and try to undo
  => you cannot undo

For an opened file, it was solved in VSCode 1.5.0 (Sept. 2016) with commit b872e3d

But for a reopened file, VSCode 1.44 (March 2020) does address the issue, which is listed in the Iteration Plan for March 2020, and assigned to Alexandru Dima: see release notes

Keep Undo stack when reopening files

VS Code will now keep the Undo/Redo stack of a file when the file is closed. When the file is reopened, if its contents hasn't changed since it was closed, the Undo/Redo stack will be restored.

This is very useful if you limit the number of open editors with the workbench.editor.limit.value setting or you accidentally close a file you are working on.

Answer 2

Undo/redo on

• a kept open file

  That normally should work. If not, it could be an issue with one of your installed extensions. Try to start Visual Studio Code on a terminal/command line with

  code --disable-extensions

• a reopened file

  It's an unsolved bug (issue #7169). Vote & give feedback in this Github issue to help solving it. The VSCode developers track Github reactions to prioritize the work.

• a saved as file

  Also an unsolved bug (issue #17977).

Answer 3

Hope this will work.

shift + command + z 

It will redo what you expected in Sublime Text (command + y )

Answer 4

For people getting to this question that want to disable the persistence of the undo stack after a file is closed, this too appears to be coming to v1.45.

See https://github.com/microsoft/vscode/issues/94778 and https://github.com/microsoft/vscode/pull/96317 and v1.45 Release Notes:

"files.restoreUndoStack": false

Set to false to disable undo stack items after a file is closed. the default is true.

Answer 5

It's now a feature in the latest version :)
