Subject: HEAD: Bug in simple.el/minibuffer.el causing display-completion-list to delete not only word to be completed but everything in file before it
Date: Mon, 28 Apr 2008 14:22:25 +0200
Message-ID: <b8c6f2610804280522o68256194yb99e57eef4c33aee@mail.gmail.com>

Problem:
In current HEAD display-completion-list deletes not only word to be
completed but everything in file before it.

example:
(defun my-complete-test ()
  (interactive)
  (with-output-to-temp-buffer "*Completions*"
    (display-completion-list
       '("test1" "test2" "test345")
       "test")))

and call that function in a buffer on the word "test" (M-x
my-complete-test) with some text preceeding "test". deletes everything
before word "test" instead of just replacing it.

This also happens when using the complete-tag function :(.

My interpretation of the problem :).

minibuffer.el: display-completion-list
 (set (make-local-variable 'completion-base-size) (or (cdr last) 0))
sets completion-base-size to 0
which causes everything to be deleted before the word to be completed.

the problem
seems to be related to completion-setup-function in simple.el checking
for completion-base-size where i believe it should check for
completion-all-completions-with-base-size
is it possible that it should read:

Index: lisp/simple.el
===================================================================
RCS file: /sources/emacs/emacs/lisp/simple.el,v
retrieving revision 1.924
diff -r1.924 simple.el
5527c5527
<       (unless completion-base-size
---
>       (unless completion-all-completions-with-base-size

after applying that patch completion works for me.

I've checked in a fix for the lisp-complete-symbol erasing buffer text
problem.
