Two questions about icicles

Two questions about icicles

[Seweryn Kokot]

Hello,

I'm trying to start using icicles and these are two things which bother
me

1. when I type C-h f char S-TAB M-* delete
I can find functions which contain "char" and "delete" in them, however
if I start to type C-h f delete S-TAB then I get that there are no
completions. Any idea what's wrong?

2. how to swap keys TAB and S-TAB in icicles-mode? I mean if I use S-TAB
more frequently than TAB then why not make life easier.  It's not simple
since S-TAB means 'icicle-complete-keys' and 'icicle-apropos-complete'
depending on context. It would be nice to have a snippet of code to yank
it into .emacs file.

regards,

No idea. It works for me.

Please use `M-x icicle-send-bug-report', providing a step-by-step recipe to
reproduce the problem, starting with "emacs -Q" (to inhibit loading init
files). Let me know what Emacs version you use, and please use the latest
Icicles files.

I'm afraid that the key used for key completion is hard-coded to `S-TAB', so
far. I'll think about making that easier to change. For now, you can change
it in the code (file icicle-mode.el):

(defun icicle-bind-S-TAB-in-keymaps-from (map)
  "Bind `S-TAB' to `icicle-complete-keys' in keymaps accessible from MAP."
  (dolist (key+map (accessible-keymaps map))
    (let ((map (cdr key+map)))
      (when (and (keymapp map)  ; Try to exclude menu maps.
            (not (stringp (car-safe (last map)))))
        (unless (lookup-key map [S-tab])
          (condition-case nil
              (define-key map [S-tab] 'icicle-complete-keys)
            (error nil)))
        (unless (lookup-key map [S-iso-lefttab])
          (condition-case nil
              (define-key map [S-iso-lefttab] 'icicle-complete-keys)
            (error nil)))))))

Change [S-tab] to [(control ?i)] - that's TAB. You can either leave the rest
as is or remove the last `unless' sexp - it is needed only because some
keyboards use a different Shift TAB key.

I installed icicles with get_icicles.sh script. 

1. 
emacs -Q -l .emacs_test

where .emacs_test file is: 
(setq load-path (append (list "~/elisp/icicles") load-path)) 
(require 'icicles)
(icy-mode 1)

2. "C-h f char S-TAB" gives no completion, 
while typing "C-h f delete S-TAB" gives completion
list where there are functions containing "char" substring. 


I use emacs22 in Debian          
GNU Emacs 22.1.1 (i486-pc-linux-gnu, X toolkit, Xaw3d scroll bars) of
2007-08-22 on raven, modified by Debian

and latest icicles files.

thanks for this elisp code, I'll try it.

That's the opposite of what you said at first, BTW: no matches for `delete',
but matches for `char'. But both should work, in any case.

Let's take the debugging off list - I'll send you a separate mail.
