Does Vertico have its plugin switch-to-buffer implementation?

I have set `C-x b` to `switch-to-buffer` and it defaults to `ido-
switch-to-buffer`.

I thought after switching to vertico-mode Vertico would substitute its
own interface for the `ido-switch-to-buffer` but its not.

What configuration option am I missing?

It does not, `switch-to-buffer` is `switch-to-buffer` and to prompt
for the buffer it uses `completing-read` which Vertico augments.

And the interface is augmented by `consult` by the same author:

vertico "just" hooks into completing-read, which is used by several
built-in Emacs functions.

There is a function called `consult-buffer`, but it's in consult.el, a
package that most users of vertico also load. It supports buffers,
recently used files, bookmarks and ... acording to it's doc-text ...
views.

No idea that Emacs has views, and what they do :-)

And no, `switch-to-buffer` doesn't default to `ido-switch-to-buffer`,
at least not in pure Emacs (e.g. called `emacs -Q`).


Personally I bound C-x b to `ibuffer` and C-x C-b to `consult-buffer`.
I almost always use C-x C-b, it's easier to type for me because I keep
the Ctrl key depressed the whole time.

This what it says in Help
>switch-to-buffer is an interactive compiled Lisp function in
‘window.el’.

>Its keys are remapped to ‘ido-switch-buffer’.  Without this
remapping,
it would be bound to C-x b, <menu-bar> <buffer> <select-named-buffer>.

>(switch-to-buffer BUFFER-OR-NAME &optional NORECORD FORCE-SAME-
WINDOW)

>  Probably introduced at or before Emacs version 17.

>This function has :around advice: ‘ad-Advice-switch-to-buffer’.

>Display buffer BUFFER-OR-NAME in the selected window.

>WARNING: This is NOT the way to work on another buffer temporarily
within a Lisp program!  Use ‘set-buffer’ instead.  That avoids
messing with the window-buffer correspondences.

How are you reading that? Because it says exactly what I tried to
explain: Ido has replaced switch-to-buffer with its own variant,
whereas the default would have used Vertico.

Your right I checked and it looks like in some undocumented indirect
way Ido had changed switch-to-buffer to its own variant.

It is not in the init.el, but it seems configured in its default
settings.
