Missing function 'gnus-get-text-property-excluding-characters-with-faces' using gnus from git

Missing function 'gnus-get-text-property-excluding-characters-with-faces' using gnus from git

Hello,

In order to apply this patch
http://permalink.gmane.org/gmane.emacs.gnus.general/84718 I am trying to
use gnus from git. I cloned the repository and compiled it, but when
I try to start gnus I get this backtrace:

Debugger entered--Lisp error: (void-function gnus-get-text-property-excluding-characters-with-faces)
  gnus-get-text-property-excluding-characters-with-faces(1 face)
  gnus-group-highlight-line("dummy.group" 1 23)
  gnus-group-insert-group-line("dummy.group" 0 nil 0 nil)
  gnus-update-group-mark-positions()
  gnus-group-mode()
  gnus-group-setup-buffer()
  gnus-group-list-groups(nil)

Note that I have not applied the patch yet, this is happening with
a fresh clone of the repository.

I'm using emacs 24.3.1.

Is this a (known) bug?

Thanks a lot,

Alan

That's odd, if I ask for documentation of that function, I get:

,----[ C-h f gnus-get-text-property-excluding-characters-with-faces RET ]
| gnus-get-text-property-excluding-characters-with-faces is a compiled
| Lisp function in `gnus-util.el'.
| 
| (gnus-get-text-property-excluding-characters-with-faces POS PROP)
| 
| The same as `get-text-property', except where `gnus-face' is set.
| If so, and PROP is `face', return the second element of its value.
| Otherwise, return the value.
`----

Admittedly with git Gnus updated in May, and GNU Emacs 24.3.50.1.


  Best regards,

    Adam

Just updated from git; I can't reproduce the problem - the function is
found in gnus-util.el by my Emacs.

Did you do ./configure && make in your checkout, and configure Emacs to
get Gnus from there?

Something similar to:

  ; My own Gnus:
  (add-to-list 'load-path "~/elisp/gnus/lisp")

in ~/.emacs.d/init.el?

Apologies for replying outside of gnus.

Is the OP perhaps running on Fedora 20?  If so,  the default emacs installation sets up your load path such that you end up with a old version of,  I think, gnus-utils, that does not have that function.   I reported this several months ago here and as a bug report to Fedora which has not been acknowledged.   My workaround is to remove the site-start.el they provide and remember to do so any time emacs gets updated by yum.

I confirm that I also see it in gnus-util.

Yes.

This is what I have in my init file:

#+begin_src emacs-lisp
(add-to-list 'load-path "~/src/gnus/lisp")
(require 'gnus-load)

(add-to-list 'Info-default-directory-list "~/src/gnus/texi/")
#+end_src

The strange thing is that if I manually evaluate the function I can then
start gnus.

The problem may be a missing autoload somewhere. If I had the following
to my init file, then I can start gnus.

#+begin_src emacs-lisp
(autoload 'gnus-get-text-property-excluding-characters-with-faces "gnus-util")
#+end_src

Should this be considered a bug? If so, where do I report it?

Thanks,

Alan

Perhaps my earlier inquiry didn't get through.  Any chance you are running on Fedora 19 or later?  I encountered what I think is the same issue about this time last year.  Fedora delivers a site-start.el file that results in an older version of gnus-util to be loaded at startup, prior to .emacs, thereby overruling any load-path fixes you might make there.  I reported it to RedHat but never did get a response.  My solution is to remove that site-start.el.  For historical context see http://comments.gmane.org/gmane.emacs.gnus.general/83524 and the follow up thread http://comments.gmane.org/gmane.emacs.gnus.general/83565

It did, but as I found a way around the bug, I did not reply, sorr.

No, I'm on OS X.

I've looked at the site-start.el files (both from the provided emacs
and from my homebrew installation) and they do not mention
gnus-util. I've started emacs with the '-q' option and I don't see it in
the features variable.

This may be a bug local only to my setup, but I'm not sure how to
investigate it.

Best,

Alan

IIUC, there must be a form in your init file which somehow loads an old
version of gnus-util.

You could try the following:

$ emacs -q

C-x C-f <your init file>

M-: (while (not (or (eobp) (featurep 'gnus-util)))
  (eval (read (current-buffer))))


(I assume that your init file does not set the lexical-binding file
local variable)

This should leave point after the offending form.

In my case, I was surprised to learn that gnus-util was pulled in by
(ffap-bindings).

Thank you for this very nice trick! I was able to figure out the issue
happens when loading my custom.el. I find two lines mentioning gnus
there:

#+begin_src emacs-lisp
 '(gnus-auto-select-subject (quote unread))
 '(gnus-buttonized-mime-types (quote ("multipart/signed")))
#+end_src

I guess I should try to delay the loadig of custom.el until after I have
loaded gnus. I'll try this next.

(Later ...)

Yes, I confirm that loading gnus before custom.el works.

Thanks again,

Alan

For the record, the (eobp) test is bogus because trailing whitespace or
comments will cause an end-of-file error if the featurep test never
returns t. So, for our diagnostic purposes, it's best to just omit the
(eobp).

Oh, and it is not a trick ;-)
