project based ibuffer

Question

I have emacs 27 on MacOS running in -nw mode. I have prelude installed. It comes with projectile.

I regularly work on two git repos in my disk.

~/client1/
~/client2/

In any given day, I would open files in both those folders. When I press C-x C-b, my list is littered with files from both my clients, and it would be cool to see a "project based" view of it.

The projectile GitHub readme says I can "switch between projects you have worked on". How?

That same readme also links to a plugin "https://github.com/bbatsov/persp-projectile", that also seems to do what I need. If that's a better option, how do I use it?

FYI "C-x C-b runs the command ibuffer (found in global-map), which is an interactive autoloaded compiled Lisp function in ‘ibuffer.el’."

Try ibuffer-filter-by-projectile-files. There are other ibuffer-filter-by-* you can use.

Try projectile-switch-project

https://github.com/bbatsov/persp-projectile/blob/master/README.md The README is pretty clear I think. You may walk through it.

Answer 2

If you are using projectile, then probably ibuffer-projectile is what you're after.

From the README:

ibuffer-projectile lets you group your buffers by their projectile root directory.
