uniquify-buffer-name-style

uniquify-buffer-name-style

[Luc Teirlinck]

Setting `uniquify-buffer-name-style' outside Custom currently only
takes effect after uniquify.el is loaded.  This misfeature is caused
by the use of defadvice in uniquify.el.  As getting rid of this advice
in uniquify.el requires non-trivial changes to the C code, I do not
believe that it would be advisable to do this at the present time.

In the patch below, I just document the misfeature and add a comment
about the desirability to get rid of it instead.  I can install if
desired.

It seems to me that adding a simple hook (abnormal) for
Fcreate_file_buffer and Frename_buffer to call could make it possible
to eliminate that defadvice, and then it would be easy to fix this
bug.

It could be tricky figuring out the right calling conventions for the
hook functions so that a single hook could do for both
Fcreate_file_buffer and Frename_buffer, and still be simple.

If we don't do this, we can document the problem, but the text you
wrote is terribly ambiguous.  In fact, I am not sure what it means.

Do you mean that:

    If you set the variable directly before uniquify is loaded,
    it won't have any effect.

Or do you mean that:

    If you set this variable when uniquify is already loaded,
    it won't have any effect unless you reload uniquify.

If uniquify is already loaded, setting the variable takes effect immediately.
Otherwise, it only takes effect once uniquify is loaded.

Sincerely,

Luc.

Please say that in the text.

Um, I'm working my way through the section `File Handling' in the manual
and came across the variable, uniquify-buffer-name-style, by way of the
node `Uniquify' and cannot find any trace of it, let alone how I might
set it to the value, forward.

  M-x customize-variable RET uniquify-buffer-name-style RET

I'm running Emacs 23.0.60.1 and I can confirm that this variable,
mentioned in (info "(emacs)Uniquify"), doesn't appear to exist according
to C-h v or customize-variable.

Cheers,

Tyler

Try putting (require 'uniquify) in .emacs.

Section 23.7.1 Making Buffer Names Unique in the manual doesn't mention
the elisp (require 'uniquify) before discussing customizing the
variable, uniquify-buffer-name-style.  Should it?

I think it's auto-loaded. C-h f uniq TAB gives a lot of functions.

Not on GNU Emacs 23.0.92.2 (i686-pc-linux-gnu, GTK+ Version 2.14.4) of
2009-04-09 on g41r2f1.

If I evaluate (require 'uniquify), the variables and the functions
become available through C-h v and C-h f.

I'm totally digging having found this variable.  I have never wanted the
path in the title bar nor---god forbid---in the mode line.  However I
often have many files named `WORKSHEET' open and initializing this
variable with `forward' so solves ... scratches an itch I have had for a
long time.  Uh-huh, this completes a little system of every project
having a file of that name and `-*- outline -*-' at the top of each.

I don't have an older version of Emacs to check this on, do older
versions auto-load uniquify.el?

It's not.  Which is stupid.

I'm running 23.0.60.1, built from cvs on Debian, as well as the
prepackaged version 22.2.1 from the Debian Lenny repository, and neither
of them have uniquify autoloaded.
