Full Text Bug Listing

The ebuild implements a wrong sed command to change the folder name for emacs
support. See attached diff for a possible correction.

Changing that, I still have problems with the maxima mode in emacs. M-x maxima
hangs. Here the messages:

For information about the GNU Project and its goals, type C-h C-p.
Loading maxima (source)...
Loading regexp-opt...done
Loading edmacro...done
Loading derived...done
Loading easy-mmode...done
Loading maxima (source)...done

I have to C-g. After that I can try again and now it works...

Created an attachment (id=84827) [details]
changed ebuild

Hi 

The 50emacs-gentoo.el file was updated in the overlay but wasn't updated in the
portage tree. Could a gentoo dev move
http://gentooscience.org/browser/overlay/sci-mathematics/maxima/files/50maxima-gentoo.el?rev=169
to the main tree? 
The patch sent in Comment #1 should not be needed then.
Then we see about the second issue.

Sebastien

Sorry - I don't use emacs and didn't realise there had been a change. I have
updated this in CVS - if you emerge it again then emacs should hopefully be
fixed. I am on a slow hotel DSL connection though and about to fly out so I may
be unable to do any more... Please reopen if problems persist.

Please change typo in 50maxima-gentoo.el:

(setq load-path (cons "/usr/shar/maxima/PV/emacs" load-path))

into

(setq load-path (cons "/usr/share/maxima/PV/emacs" load-path))
                           ^^^^^^^

The typo really need to be changed to have the emacs support working...

Thx

Yes I fixed the path problem manually,
but I still have to press C-g, otherwise emacs halts there

what's wrong?

I am using maxima-5.9.3 with sbcl-0.9.12

RE: comment #6 Confirmed - the maxima program hangs in the function
inferior-maxima-wait-for-output which is defunned in maxima.el at line 2706.
Changing the 'while' to a 'when' seems to fix it:

(defun inferior-maxima-wait-for-output ()
  "Wait for output from the Maxima process."
  (when (and 
          inferior-maxima-waiting-for-output
          (inferior-maxima-running))
    (accept-process-output inferior-maxima-process))
  (if maxima-running-xemacs
      (sleep-for 0.1)
    (sit-for 0 inferior-maxima-after-output-wait)))

Maybe this should be made into a separate bug?

I haven't tried this because I don't see a patch in there for the
inferior-maxima-wait-for-output bug. Am I missing something?

merged. See:

Works. Thx

(In reply to comment #10)

Didn't see that - even though I did actually look inside the file %-)
Thanks! :) 

sci-mathematics,
the file 50maxima-gentoo.el is still broken in the portage tree.  To fix this,
either grab
http://www.gentooscience.org/browser/overlay/sci-mathematics/maxima/files/50maxima-gentoo.el
 or apply the following patch:

bump, this is an easy fix.
(see comment #13)

Thanks for adding me to the CC Christian - really busy right now and so I don't
always get the time to read all my bugzilla email... I have added the updated
emacs file from the overlay and bumped to 5.11.0. Hopefully this will correct
the problems with the emacs mode.

I would like to thank Andrey Grozin <A.G.Grozin@inp.nsk.su> and  Sebastien
Fabbro <seb@ist.utl.pt> for all their hard work on this ebuild in the overlay.
