It’s amazing how many packages for our beloved editor exist out there. ELPA and MELPA keep growing and growing, and curiosity is always pushing me out to look for a new package to try.

Last year I wrote about Eyebrowse, a cool workspace manager that has proven to be a reliable friend until recently. Eyebrowse is a helpful extension, but as it turns out the built-in Ibuffer is enough to make sense of all of the buffers available. I open it with C-x C-b, which is one of the most used key bindings in my everyday Emacs interactions.

Ibuffer presents a customizable list of buffers on which, much like Dired, we can apply different kinds of operations: filter, sort, group, mark, delete, bury, visit. Just press h in Ibuffer to get an idea.

Since I mainly work on projects versioned on Git, ibuffer-vc helps with grouping the buffers in a project-based fashion and operate on them. For instance, to quickly close a project and its related buffers, mark the project header for deletion with d and then press x.

One thing I was missing in Ibuffer was an integration with Magit. I wanted to open magit-status in the project the current buffer (i.e., the buffer where point is on) belongs to.

(defun mu-ibuffer-magit ()
"Open magit-status' for the current buffer."
(interactive)
(let ((buf (ibuffer-current-buffer t)))
(magit-status (cdr (ibuffer-vc-root buf)))))


I’ve bound this function to v in ibuffer-mode-map. Note that v was previously calling ibuffer-do-view`, so you may want to pick the key that suits you best.
