[feature] support for history tree (undo redo tree)

[trusktr]

In plain vim, I use plugins like mbbill/undotree to see and navigate the history tree.

It would be neat to have something like this inside VS Code. So useful!

So perhaps this could be made to work by editing the plugin(s) to call vscode split/window commands instead of the vim commands? Is that likely to be straighforward?

The extension can work with a buffers originated from neovim, but will skip any initially empty ones. That's why :help works (contains text) but PlugStatus doesn't (a content does appear slightly later here).

So immediate workaround is to try to fill something when gundo/undotree buffer is being created, something like this can possibly work:

autocmd BufAdd [gundo-buffer-name/wildcard] <code to insert something (any text) into the buffer>

@asvetliakov 👍 ok that seems to sort of work:

autocmd BufAdd __Gundo__ call appendbufline("__Gundo__", "$", " ")

However, yeah it takes over the whole editor, and doesn't seem to actually function to edit history because it can't find the buffer to change:

Maybe the best solution would actually be a new vscode plugin that connects vim undo branches with the new VSCode Timeline view.

That's probably because that buffer is being disconnected and inserted into new window, so original binding to parent windows is lost and breaks the plugin

Maybe the best solution would actually be a new vscode plugin that connects vim undo branches with the new VSCode Timeline view.

VScode doesn't have api for that, also i don't think vscode timeline supports undo branches (actually it has some). You can try though to use vscode undo stack, just map u/<C-r> to vscode's undo/redo

I have some plans to improve such buffers support, but it would take some time.
