Singular emacs interfaces appears to not be fully functional

[paulo.cesar.pereira.de.andrade@…]

I maintain a Singular package in Fedora, and it was reported an error message when starting emacs. My first guess is that it would be better to disable the emacs interface package, as the last Changelog entry is from 2000, but Singular maintainers may have some extra comment.

The Singular rpm bug report is at ​https://bugzilla.redhat.com/show_bug.cgi?id=1011287 and you can look the the rpm sources at ​https://pkgs.fedoraproject.org/cgit/Singular.git

Use ESingular instead.

The problem seems to be in your Singular.spec file:

mv $RPM_BUILD_ROOT%{_emacs_sitelispdir}/singular/.emacs-singular \

$RPM_BUILD_ROOT%{_emacs_sitestartdir}/singular-init.el

The file .emacs-singular is not supposed to be copied into the emacs start directory (see information in the header of this file). It should only be loaded when emacs is started by ESingular which will first set the variable singular-emacs-home-directory.

I used to use emacs long ago, but not for over a decade, so I think I cannot correct the other issues that happen when doing the correction suggested above. After that, running ESingular I see in the emacs *Messages* buffer:

Loading /usr/share/emacs/site-lisp/site-start.d/asy-init.el (source)...done

progn: Symbol's value as variable is void: current-menubar

If I click the Singular menu, I see the options:

+---------------+
| Start default |
| Start...      |
+---------------+

If I click "Start default", in *Messages* I see:

Symbol's function definition is void: singular

If I click "Start..." I see in *Messages*:

Symbol's function definition is void: singular-other

I would prefer to correct any remaining issue instead of no longer generating a Singular-emacs package... Any idea as to what I may be missing?
