case sensitivity in 'find file'?

case sensitivity in 'find file'?

[Viktor Haag]

I'm using Emacs 21.3.50.1 built on Mac OSX through the Fink
project with the tarball 'emacs-21.3.50-20040617.tar.gz'.

I've seen new behaviour that I don't like; when I use 'find-file'
the completion now seems to be case-insensitive. I find this
annoying as it now sees ~/Library and ~/lib as similar requiring
more keystrokes when finding a file in the ~/lib subtree.

There must be a way to retrieve the old case-sensitive behaviour
so that ~/Lib and ~/lib are matched as different names.

Can some kind soul please let me know where the variables are
that control this behaviour?

completion-ignore-case?

There isn't presently an obvious way because the builtin
`read-file-name' was changed to bind `completion-ignore-case' to t
before calling `completing-read' on DOS, NT, VMS and MACOSX systems.

You could partially revert that change to Fread_file_name, eg:

--- fileio.c	22 May 2004 23:17:17 +0100	1.505
+++ fileio.c	23 Jun 2004 17:19:07 +0100

     }
 
   count = SPECPDL_INDEX ();
-#if defined VMS || defined DOS_NT || defined MAC_OSX
+#if defined VMS || defined DOS_NT
   specbind (intern ("completion-ignore-case"), Qt);
 #endif

Maybe there should be a `read-file-name-completion-ignore-case' user
variable ?

Unfortunately, no. I checked that, but it's currently set to
'nil' which should make it case-sensitive.

That sounds like a fine idea, because I can easily see that users
might prefer this behaviour be configurable.

Wanna send a patch to emacs-devel ?

I'd love to, but I'm not up to that level of work; I'm a
technical writer not a developer, and my competency with
emacs-lisp (or C) is not really that great.
