Hi,

I am trying to replace ido with fido.

One heuristic that I miss from ido is the ability to easily get to 
root via find(ing)-file.

In particular, from emacs -q, I might do something like this

    (let ((default-directory "~/")) 
      (fido-mode) (call-interactively 'find-file) ;; click 
      <backspace><backspace> to get to root )

Being an ido-user, I would expect to be able to go to /home/ by 
clicking backspace and then to root.  But I doesn’t work with 
fido.

I don’t know if I have missed some obvious configuration-step 
here?  I looked through the customization groups of both icomplete 
and minibuffer.

The attached patch expand the file-name if it is “~/”.

I am not really familiar with this part of Emacs so I am not sure 
it’s the right way to go about it.  In particular, I am really not 
sure whether the internal functions (e.g. ‘icomplete--field-beg’) 
are used correctly.


Aside: Another annoyance with fido is that $HOME isn’t being 
abbreviated
to “~” when browsing from root.  E.g.
 
    (let ((default-directory "/home/")) 
      (fido-mode) (call-interactively 'find-file) ;; now select 
      your username ) 

I would like “/home/$USER” to be abbreviated to “~” (like ido) to 
conserve space.

Any ideas as to where such a change migh be injected to fido?  I 
didn’t see an obvious place.

Thanks in advance,
Rasmus
