Description:   Opened: 2008-06-06 14:20 0000 
When Singular is installed with the emacs useflag it still does not provide
full emacs integration. 

Reproducible: Always

Steps to Reproduce:
1. Install Singular with emacs use flag and load emacs with (require
'site-gentoo) in the init file
2. M-x Singular
3. Define a ring with "ring R = 0,(x,y),lp"
4. press M-p 

Actual Results:  
1) When starting Singular in Emacs 2 Errormessages are given, indicating that
certain files are not found. At least the given helpfile is nowhere to be found
on my system. 
2) M-p inserts the last command in front of the prompt making it unusable.
3) TAB-Completion does not work.

Expected Results:  
No error messages and functional M-p/TAB-Completion/...

------- Comment #1 From Ulrich Müller 2008-06-06 17:49:35 0000 ------- 
You are hit by several independent problems here:

> 1) When starting Singular in Emacs 2 Errormessages are given, indicating
>    that certain files are not found. At least the given helpfile is
>    nowhere to be found on my system.

Hm, singular-3.0.4.2-gentoo.diff already patches the path names in the source,
but looks like it doesn't do it right. At least SINGULAR_EMACS_DIR and
SINGULAR_INFO_FILE are wrong (I didn't check the others).

Also, the Info file is only installed with USE=doc.

> 2) M-p inserts the last command in front of the prompt making it unusable.

I believe that this should be reported upstream. They are using Emacs' comint
mode in a strange/nonstandard way.

As a workaround, you may set "comint-use-prompt-regexp" to t.

> 3) TAB-Completion does not work.

This should be fixed if the paths from 1) are set in the right way.

------- Comment #2 From Thomas Kahle 2008-06-07 09:58:03 0000 ------- 
Hi, 
some remarks.
In the described setup the "doc" useflag is also set. 
The help partially works. 
C-c C-h shows the list of available singular-emacs commands, as it should.

typing "?ring;" on the Singular commandline(outside emacs) correctly shows help
on "ring", ie. it launches firefox on:
file://localhost/usr/share/doc/singular-3.0.4.2/html/sing_149.htm#SEC189
which shows the corresponding topic. 

Doing the same thing in the emacs-singular prompt results in the Emacs Help
Browser starting, but showing something different, not related to Singular.
Probably this is just an indication of the info file not to be found... ?

------- Comment #3 From Markus Dittrich 2008-06-07 12:50:06 0000 ------- 
I fixed the paths and things seem to work well now inside
emacs. If there are any additional issues I'd appreciate if
somebody could provide a patch since I don't know emacs very
well at all.

Best,
Markus

------- Comment #4 From Thomas Kahle 2008-06-11 10:03:18 0000 ------- 
I reported the "M-p inserts before prompt issue" upstream, referring to this
bug.
They don't have a public bugtracking system, but maybe they answer here.

------- Comment #5 From Markus Dittrich 2008-06-12 13:22:39 0000 ------- 
Thanks, Thomas!

I'll close this bug as "upstream". Please, don't hesitate to
reopen in case there are any news.

best,
Markus

------- Comment #6 From Thomas Kahle 2008-06-30 09:32:55 0000 ------- 
They are working on it, saying that it has to do with changes in emacs. 
The problem does not occur in <=emacs-21.* and xemacs.

------- Comment #7 From Markus Dittrich 2008-06-30 09:47:33 0000 ------- 
Thanks for the note! Let's hope they get it 
figured out.

Best,
Markus
