You're right. It does *not* work. I don't know why I have had the impression
it was working...

But, nope, if you don't have W3M installed, you'll get Emacs stopped during
loading the conf file. Very very annoying.

Removing references to "w3m" from anything-config.el seems a rather
pervasive fix.  I'll check whether the maintainer is willing to do it.

However, please note that "anything-config" is not necessary for
"anything" to work.  It's just a shared configuration from an user.

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

[Elena]

Thierry Volpiatto, an anything-config maintainer, has quickly and
kindly answered my questions about the issues we are experiencing.  He
has asked me to forward his reply on this newsgroup, which I'm doing
right now.

Thierry's reply follows:

There is no dependency on w3m, it is not needed.
I just tried it on windowsXP in a virtualbox with no problem.
I think these user have old sources of anything in their config or old
versions of anything-config.el.
Please try again with emacs -Q and just require anything-config.el.
use last versions from git:
URL             git://repo.or.cz/anything-config.git
                http://repo.or.cz/r/anything-config.git

However trying that, i just notice that anything-find-files fail if
tramp is not loaded.
I will commit a fix for that in few minutes.

Could you forward this on emacs-help?
Thanks.

No, you should use anything-config.el.
If you don't use it you will have a poor experience with anything even
if anything (alone) work.

The correct way to install anything is:

(require 'anything-config)

You need only the files anything.el and anything-config.el.

You can also require anything-match-plugin.el that's all.

There is not such code in anything-config.el or anything.el,
this error message come from somewhere else.

Something other than anything-config.el or anything.el is loaded
somewhere in your config, or you use old libraries of anything.

As said to Elena, i can't reproduce this on a windowsXP without
w3m.

Please start with emacs -Q and (require 'anything-config)
No more.

Thank you, Thierry, for helping us.  Indeed, the issue is absent in
"emacs -Q".

I've found the offending line to be:

(eval-when-compile (require 'w3m-bookmark nil t))

Both the original poster and I have downloaded the "emacs-w3m"
interface, which contains "w3m-bookmark".  Emacs fails to load this
package on Windows, because the external app "w3m" is missing.

I solved the issue by restarting Emacs without the "emacs-w3m"
directory in its load-path.

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):

Yes, that's the same problem.  I think a fix would be to add "emacs-
w3m" directory only when "w3m-command" is defined and available, like
this (snippet not tested, I'm busy right now):

;; Add emacs-w3m path to load-path only when w3m-command is available.
(when w3m-command
	(if (executable-find w3m-command)

I've read something about this issue, but I don't remember what the
fix was.  If I'm not mistaken, creating "*anything*" buffer in advance
fixed the issue.  Sorry for not being able to provide definitive
answers right now.

In my case, it is a bit different as the load-path is automatically computed
(recursive scan of all folders under the root one)...

Maybe it'd be good that to be checked directly in the `anything' package?  The
assumption that such a buffer already exists is maybe too strong?  Or I do
something wrong so that the assumption gets broken?

You're welcome. That's how we all can make progress...

Just like mine is.  However, I've put "troublesome" packages into a
directory at the same level as my auto-scanned root directory (that
is: not a child of the latter).  I've done that with other folders
which are included on a case basis: OS specific packages, "backports"
from newer versions of Emacs, etc.  Moreover, I've tweaked the
procedure which adds directories to leave out those which end with
".BAK" or ".OLD".  That way it's easy to just rename a directory and
have it left out.  I'll post my tweak when I have time.

I don't remember/know whether it is an issue of anything.el.  Maybe
it's a contributed package?  Yes, contacting the maintainer is the
right solution.

Please use:

(require 'anything-config)

nothing else.

Then start adding your personal code progressively and see step by step
what is wrong.

I got a very minimal configuration now...

#+begin_src emacs-lisp
(message "Minimal Emacs...")

(add-to-list 'load-path (expand-file-name "~/src/anything-config"))

(setq debug-on-error t)

      ))

;; allow input of accented characters
(set-input-mode nil nil 1)

(message "Minimal Emacs... Done")
#+end_src

which exhibits the following error:

Remove this, incorrect and unneeded.
Just use f5-a l or see anything menu.

Don't know about your locale setting, but normally you don't need this.

BTW, you can use now the anything mailing list.
