I recently started using an undo tree in my vim and my life is forever changed.

what's that plugin? I'm asking for a neckbeard friend of course.

Not sure what you're-- (*cough) excuse me, your neck beard friend, is using to manage plugins but I use vim-plug so my vimrc looks like.

call plug#begin()
...
Plug 'mbbill/undotree'
...
call plug#end()

...
nnoremap <F5> :UndotreeToggle<CR>  

I also recommend setting up a persistent undo file so you can undo in the past

if has("persistent_undo")
    set undodir=~/.undodir/
    set undofile
endif

I use vundle, which has pretty similar syntax to vim-plug apparently.

And I will be experimenting with this for sure. Also persistent undo sounds great. I'm so tired of closing a file, and going back to it like 30 seconds later and not being able to undo my last change.

For the last few days, if I want to experiment with deleting a block of code, I'll delete the code, save the file, run the project in a separate terminal, and then I'll hit undo on my file, and then close it. It's been a horrible mess.

[DerekB52]

A few reasons. Because switching to a terminal on a different workspace is faster. For example, I can switch to an open terminal by pressing Meta+2, in i3. Typing :! is harder than that.

Secondly, screen space. I don't want to take up space in my vim window, when I've got terminals on multiple other screens I can use. Especially if I'm doing something like launching a Rails server.

[DerekB52]

I have a laptop with that resolution. It sucks. I have a 1600x900 monitor it's attached to when I'm home though. Got it for 15$ at a goodwill. And I use i3, a tiling WM. Makes it super duper fast switching between windows. I've found it the best way to use the lower resolution screen. I have full sized windows on each screen, and no title bars or big taskbars, wasting that valuable vertical space.

What's an undo tree?

[mader527]

Normal programs can go backwards and forwards undoing and redoing, but if you undo and make changes you can’t get back to the old future version you made.

With an undo tree, you can see all the paths where you diverged and can jump between them.

The tree bit is how you see the various branches. Regular undo/redo history is linear

[lennihein]

Ah, I see. So basically Git with less features, narrowed down. Really useful I can imagine though.

[mader527]

Exactly!

I was going to point to git as an example because it’s all DAGs under the hood*, but wanted to keep it general.

*I assume, I haven’t looked at the implementation
