Configure SPACE as file auto-complete character

Configure SPACE as file auto-complete character

[Bruza]

I just installed emacs 22.1.1 GTK on Ubuntu. The first thing I noticed
is that the auto filename completion key in the min-buffer is not
SPACE anymore. I need to use TAB instead. Is there a way I can
configure SPACE as the filename auto-complete character?

C-h n
C-s space

This is so you could use file names with spaces.

See this entry in NEWS (and the one it refers to):

  ** When Emacs prompts for file names, SPC no longer completes the file name.
  This is so filenames with embedded spaces could be input without the
  need to quote the space with a C-q.  The underlying changes in the
  keymaps that are active in the minibuffer are described below under
  "New keymaps for typing file names".

C-h n C-s space:

Interesting... I've had the following line in my ~/.emacs for quite a
while for precisely this reason:

;;; disable 'SPC' completion in minibuffer
(substitute-key-definition 'minibuffer-complete-word 'self-insert-command minibuffer-local-completion-map)

However, I believe my substitution disables auto-completion across the
board, not just file name auto-completion.

And that's a good thing, IMO.  I doubt that you regret it.

Completion using `completing-read' is general; there is nothing that
suggests that it should be mainly for text that doesn't contain spaces. Why
does Emacs limit space self-insertion to file-name completion?

Thank goodness for at least that change. It was due at least in part to the
widespread use of MS Windows (and also to the fact that word-by-word
completion is not so useful).

FWIW - In Icicles, each of these characters self-inserts in the minibuffer:
`?', `C-j' (newline), and `SPC' - regardless of the input type. You can
still do word-by-word completion, using `M-SPC' (configurable), but I'm sure
that any use of word-by-word completion is rare.

But, back to my original question, if I like to keep the SPACE as the
file
auto-complete character, how can I configure it back to the pre-
version 22
behavior?

Thanks,

Ben

Yes that change is a real pain. I guess I need a space in a filename
about once or twice a year here in our Solaris/GNU Linux environment. I
wish there was an option to switch back to the original behavior or even
better this change would be the default for Microsoft users only.

Here's what I added to my .emacs file:

(if (>= emacs-major-version 22)
    (if partial-completion-mode
	(progn
	  (define-key minibuffer-local-must-match-filename-map
	    (kbd "SPC") 'PC-complete-word)
	  (define-key minibuffer-local-filename-completion-map
	    (kbd "SPC") 'PC-complete-word))
      (define-key minibuffer-local-must-match-filename-map
	(kbd "SPC") 'minibuffer-complete-word)
      (define-key minibuffer-local-filename-completion-map
	(kbd "SPC") 'minibuffer-complete-word)))

Ah!  Yes... good question.... Drew?

I thought someone had answered that already. The Emacs NEWS - or more
likely, the Emacs manual Anti-News, should explain that. At least the NEWS
mentions that this is controlled in the file-name completion maps (which are
new with Emacs 22, mainly to accommodate the fact that they didn't want this
space change also for non-file-name completion). It says this, which is
correct but perhaps not sufficiently clear:

 "The underlying changes in the keymaps that are active in the
  minibuffer are described below under `New keymaps for typing
  file names'."

Anyway, Klaus has now shown you how - you just need to change the binding of
the space character in the file-name completion maps.

[For Icicles: Space completion a word at a time is determined by option
`icicle-word-completion-keys' - just set it to the key(s) you want for that.
And if you don't want space to complete a word at a time, but you also don't
want space to self-insert, then do the same thing that Klaus showed, but for
all minibuffer completion keymaps.]

Thanks for all the help. I can now finally "claim" my SPACE back :-).
