Cannot turn off buffer preview in switch-buffer

[franburstall]

Describe the bug

I would like to turn off the buffer preview in switch-buffer because it makes the buffer order for C-PageUp/Dn unpredictable.

I thought I would achieve this by configuring the follow-p slot of buffer-source to nil. This writes

(DEFINE-CONFIGURATION BUFFER-SOURCE
  ((PROMPTER:FOLLOW-P NIL)))

to auto-config.lisp but, even after restarting nyxt, this does not have the desired effect: I still have buffer preview in switch-buffer.

How do I switch off buffer preview?

I'll investigate. Note that you can disable 'follow-mode' interactively with C-c C-f.

Thanks, that is helpful. But C-c C-f doesn't persist to the next invocation of switch-buffer. Moreover, there is a single "follow" before you can do C-c C-f which inserts that buffer between source and target in the last-access ordered buffer-list.

[Ambrevar]

That C-c C-f is not persisted is normal, there is no option for it at the moment.
I've added an entry to remember to implement it here: atlas-engineer/prompter#32

Do you know the resume-prompt command? If you resume a prompt its whole state is remembered, including follow-mode. Depending on the prompt, the list of suggestions might not be up-to-date though. This is by design.

[Ambrevar]

To be really useful, resume-prompt would need a binding. Any suggestion?

C-c C-r?

Let's keep thinking about it in atlas-engineer/prompter#32.

This issue is fixed with a276091.
Thanks again for your support!

I've also updated switch-buffer to not set current-buffer is last. This was annoying me as well. It would constantly shift my buffers when I was doing switch buffer. Therefore, Fran, you should be able to just use normal switch buffer now with the preview.

@jmercouris: I will give this a go. That said, I rather enjoy the no-fuss of having the preview switched off!
