How to do this Vim Trick in Emacs?

Saw this neat vim trick and was curious how I could pull this off in emacs. [https://youtu.be/futay9NjOac?t=431](https://youtu.be/futay9NjOac?t=431)

That's neat! I tend to make a keyboard macro or maybe `M-s o` with some post processing. Definitely not as quickly as he did it though.

I would use `mark-defun` and `occur` to obtain the initial text matching the regexp, copy the text from the occur buffer, yank it, and then maybe `exchange-point-and-mark` to reactivate the mark/region, and search/replace (in region). It's not as streamlined as that video, but it's still pretty simple.

You can do something similar with [multiple cursors](https://github.com/magnars/multiple-cursors.el).

I think giving a prefix arg to occur and using a more exact regexp should alleviate some of the pain later on.

Using evil in emacs you'd just do exactly what he did in vim, using the same exact commands.

Looking for non vi mode. I prefer mod keys to modal editing personally. Thanks for the tip though!
