[feature request] Getting Spacemacs to keep from shuffling buffer order

[stradicat]

Situation: editing buffers A - B - C - D - E, navigated in a left-to-right fashion with C-x ← and C-x →, then invoking some command like magit, closing the transient overlay and going back to buffers.

Now the buffers are ordered as A - C - E - [some lsp log] - D - [some other log]. It gets a tad annoying after a while, since one has to keep going to C-x b buffer-name instead of just going sideways (some ThinkPads have integrated page keys that trigger C-x ← and C-x →).

For comparison purposes, doom-emacs doesn't exhibit this apparently random reordering.

I haven't found a way to keep the buffer order yet, hence this call for help.

It looks even more counterintuitive when using centaur-tabs to keep an eye on open buffers for a project. Adjacent buffers show adjacent tabs on the upper border of the current window, yet they're not cycled sequentially.

So far, after experimenting for a couple of weeks, I haven't been able to find any setting that could prevent this behavior, not even centaur-tabs' tab/group order settings, so my gues is that it could be a Spacemacs thing.

The issue is still valid.

The order of the buffers in this list is based primarily on how recently each buffer has been displayed in a window.

A buffer moves to the front of this list whenever it is chosen for display in a window (see Switching Buffers) or a window displaying it is selected (see Selecting Windows).

https://www.gnu.org/software/emacs/manual/html_node/elisp/Buffer-List.html

Importantly,

There are no functions available to the Lisp programmer which directly manipulate the buffer list

So I don't how doom could possibly fix the order.

Also, you need to provide a concrete list of steps to reproduce the behaviour.

That's exactly why I find it puzzling. Under doom-emacs, the buffer order remains unaltered. Under Spacemacs, it is modified.

Also, you need to provide a concrete list of steps to reproduce the behaviour. I can only sum this up as:

• Situation: editing buffers A - B - C - D - E
• Navigate between buffers in a left-to-right fashion with C-x ← and C-x →
• Invoke some command like magit, closing its transient overlay (e.g. to save a commit)
• Go back to the last edited buffer
• Navigate again between buffers in a left-to-right fashion with C-x ← and C-x →
• See that the buffer order has changed.

This is in no way urgent or show-stopping, merely a low-priority annoyance. If there's a way to fix it, it would be nice; if not, no problem.
