Re: "Anything" package requires w3m command...

[Sébastien Vauban]

Hi Elena and Thierry,

Thanks Elena for having gone ahead with this thread... and contacted Thierry.

Regarding `w3m-bookmark', I indeed saw such messages in the past. It must be
related to the problem.

Now, following Thierry's advice, I've git pull'ed `anything' just 10 min ago,
and tried to relaunch my Emacs.

I now have a different error (maybe hiding the above one, from a previous
run):

--8<---------------cut here---------------start------------->8---
Warning (initialization): An error occurred while loading `c:/home/sva/.emacs':

error: No buffer named *anything*

To ensure normal operation, you should investigate and remove the
cause of the error in your initialization file.  Start Emacs with
the `--debug-init' option to view a complete error backtrace.

and the following backtrace:

with the following lines in my `.emacs':

Do you have an idea why this is occurring?

PS- By far, what I really want `anything' for is the `locate' stuff...

PS2- My `require' is wrapped to output debug messages:

--8<---------------cut here---------------start------------->8---

         ;; redefine require to leave a trace of packages being loaded

             (fset 'orig-require (symbol-function 'require))
           (message "The code to redefine `require' should not be loaded 
twice"))

         (defvar my/require-depth 0)

         (defun require (feature &optional filename noerror)
           "Leave a trace of packages being loaded."
           (cond ((member feature features)
                  (message "%sRequiring `%s' (already loaded)"
                           (concat (make-string (* 2 my/require-depth) ? )
                                   "+-> ")
