26.0.50; Show Ibuffer and jump to line listing current buffer |
|

Severity: wishlist
Suppose current buffer is *foo*, then `list-buffers'
list the buffers with point set at the line listing *foo*.
In the case of `ibuffer', if *Ibuffer* already exists,
the effect of this command is pretty much like
(switch-to-buffer "*Ibuffer*")
i.e., the point is preserved. This is useful, but quite often
i wish the other behaviour:
To show *Ibuffer* and set point at the line listing *foo*.
This is handy when you have customized `ibuffer-saved-filter-groups',
and you have many lived buffers.
We might get this behaviour in several ways:
1) Via prefix argument: we already use a raw prefix to decide if we
display *Ibuffer* in a new window or in the current one.
It might be possible to define prefix "C-u C-u" to mean
show *Ibuffer* with point at the line showing *foo*.
This would work but not the easiest to type solution, though.
2) Add a new function:
(defun ibuffer-jump (&optional other-window-p)
"Call Ibuffer and set point at the line listing the current buffer."
(interactive "P")
(let ((name (buffer-name)))
(ibuffer other-window-p)
(ignore-errors (ibuffer-jump-to-buffer name))))
3) Add a new option, something like
`ibuffer-point-at-current-buffer'.
When this option is not nil, then `ibuffer' set
point at *foo*.
I prefer 2) over 3) because i can get both behaviours with easy
in the interactive session.
