List Undo Branches

One thing you might not know about Vim is that behind the scenes, to do its undo and redo processes, it actually maintains a tree structure. The best way to think of a tree is to think of a Git repo and how it has a bunch of different branches. Basically, it is the same sort of idea.

Therefore, when you make a modification in Vim, it is going to branch in some other direction. Now, when you use undo and redo in Vim, it is not entirely clear that you are working with a tree. Because Vim is going to decide the best branch to jump onto, however, you can move around this tree normally.

The problem is though, if you are working with a tree and you do not have a visual representation of it, it is going to be very hard to work out where you are going to be jumping to. So, you can use plugins such as UndoTree to add a visual representation of the tree and list undo branches to make navigating it much easier.

Example about using undo branches in Vim

Here are some examples to make you more familiar with using undo branches in Vim:

Go to your terminal application.
Make a demo file using the following syntax:

$ vim demo.txt

Press “i” to add the below text:

Linux macOS Unix monovm

Remove the word MacOS by pressing “x” as many letters as the word contains (five times):

Linux Unix monovm

To undo the latest changes, you need to press “u” five times:

Linux macOS Unix monovm

How to undo and redo in Vim 3?

List tree of changes

While you may use the Vim undo and redo commands, the changes you make in this editor have never remove completely. Therefore, you can access and list tree of changes using the following command:

:undolis

Note:

The output would be something like the above picture. Each column has its specific description:

The first column shows the number of changes, which will be increased whenever you create any removable changes.
The second column identifies the number of changes created from the root.
The third column shows the exact date and time for creating changes.
The fourth column identifies the files related to changes you recently made. To observe these files, you can use the “:later” or “:earlier” commands using the following syntaxes:

:earlier {count} (Go to the earlier text state {count} times) :earlier {N}s (Go to earlier text state {N} seconds before) :earlier {N}m (Go to the earlier text state {N} minutes before) :earlier {N}h (Go to the earlier text state {N} hours before) :earlier {N}d (Go to older text state {N} days before) :later {count} (Go to the newer text state {count} times) :later {N}s (Go to the newer text state {N} seconds later) :later {N}m (Go to the newer text state {N} minutes later) :later {N}h (Go to the newer text state {N} hours later) :later {N}d (Go to the newer text state {N} days later)

For example, you can use the following syntax to go back four days:

:earlier 4d
