partial completion and switch-to-buffer

partial completion and switch-to-buffer

[Tobias Gerdin]

Greetings,

With the advent of partial-completion-mode in Emacs 23, I was wondering
if there isn't any way to use this mechanism with switch-to-buffer ("C-x b")?

Switch-to-buffer still seems to do only prefix-matching.

I am aware of iswitch-mode and ido-mode, which does substring matching
(which is basically what I want), but find them too obtrusive. I do not
want any completion to be done unless I say so (by pressing <tab>).

I'm using Emacs CVS from 2009-07-30 (i.e. pretty much 23.1).

so far as my studie goes, the partial completition does not always
works, perhaps by intention. However, wildcard works. So, just put a
wildcard “*” in front first.

might be of interest (contains some example):

Icicles does no completion until you say so (by pressing TAB), by default.

http://www.emacswiki.org/cgi-bin/wiki/Icicles


----

Details -

* To get substring completion instead of prefix completion, use S-TAB.

* Or, if you want to use TAB for both prefix and substring completion, then set
option `icicle-cycling-respects-completion-mode' to t. (Use TAB / S-TAB to
change the completion mode: prefix / substring.)

* S-TAB actually does regexp completion, by default. To get only substring
completion, set option `icicle-regexp-quote-flag' to non-nil. Or use `C-`' in
the minibuffer to toggle it.

* When buffer *Completions* is showing, the completion candidates are updated as
you type (incremental completion), by default. To turn this off, set option
`icicle-incremental-completion-flag' to nil. Or use `C-#' in the minibuffer to
toggle it.

Thank you.  I thought I tried that and found that it didn't work but it
did. However, I would really like not need to put the star there, since
it's a shifted char on my layout and really slows things down. Would
have been nice if a partial match was attempted directly. Since the list
of buffers is available in memory even a partial search should be very
quick.

I think I will just cook up something simple by myself, but I
find it odd that a stock Emacs doesn't do it this way.

I am aware of Icicles, but I would prefer not to have to rely on
an external package for this simple matter.  But thanks for the thorough
explanation.
