recentf: abbreviate paths? tilde for home folder?

[David Reitter]

How can I get recentf to show abbreviated paths in the "Open Recent"  
menu?
That is, show paths just like in buffer names, where path names are  
shown only where necessary in order to distinguish between existing  
buffers.
At least, I'd like to be able to replace my home folder with a tilde  
where possible.

thanks.

[ In Emacs 22 (CVS)...]

(setq recentf-menu-filter 'recentf-show-basenames) or
`M-x customize-variable RET recentf-menu-filter RET'

(defun rs-recentf-filename-handler (name)
  (replace-regexp-in-string (concat "\\`" (expand-file-name "~")) "~" name))
(setq recentf-filename-handler 'rs-recentf-filename-handler)

Bye, Reiner.

Could recentf-menu-filter be change into list of filter functions, so
that one could write the following, for example?
,----
| (setq recentf-menu-filter '(recentf-show-basenames recentf-arrange-by-mode))
`----

Why not just (setq recentf-filename-handler 'abbreviate-file-name)

Probably, just a small matter of programming I'd guess. :-)
Maybe the sorting an displaying should be decoupled.

IMHO `recentf-arrange-rules' should have more entries e.g. like
`msb-mode' (see `msb--few-menus' or `msb--very-many-menus').  Maybe
these lists or `auto-mode-alist' could be used in `recentf.el'.  (The
problem is that msb checks the mode of buffers whereas recentf has to
rely on the filename.)

Bye, Reiner.

Thanks for pointing this out.  I think `abbreviate-file-name' should
be added as a choice in the defcustom of `recentf-filename-handler'.

[ BTW: Emacs 21 doesn't offer `recentf-filename-handler' so it might
  not be useful for David. ]

Bye, Reiner.

Reiner, Kevin:

(setq recentf-menu-filter 'recentf-show-basenames  )

is exactly what I wanted, thanks very much.

Now, I've changed that function to produce the same syntax as used  
for buffer names (or in the buffers menu - don't know which one it  
is) with the "--" instead of showing the path in parenthesis. I  
wanted to use uniquify to produce exactly the same behavior (i.e.  
abbreviated paths where necessary), but it looks like uniquify only  
works with buffer names and not simply with an arbitrary list of path  
names :-(

Thanks again
David

How about:

(setq recentf-menu-filter
       (lambda (menu-elements)
         (recentf-show-basenames (recentf-arrange-by-mode menu-elements))))
