[cantor] [Bug 312738] Should import Sage LaTeX macros

@Filipe from comment 10:

I understand completely, and thank you for your reply. I wholeheartedly
appreciate you cannot of course do all this alone. The fact that Cantor has got
this far is tribute to the efforts yourself and all the others who do
contribute are putting in.

Yes I would like to help. Starting with decent bug reports is totally ok with
me.

I'll add a couple of points as I see them:

1) 10 languages is far too many, let's support a few of them but support them
well?
2) The interface basics in Cantor need to be stabilised
3) support for LTS versions - a new install of Kbuntu for every minor bugfix
drives users away

As for me, I could contribute to the sage plugin, I have been checking through
the code - I am not up to your level with understanding and packaging the
everything right now, but if I could get in touch with you, perhaps I can
experiment/develop the code and send it to you for approval? I am interested in
making sure the LTS backports are as up to date as we can make them and
available on the repos. 

I am also interested in adding more sage specific features to the plugin. Sage
uses a browser for its notebook, but that approach eats up a lot of memory per
notebook - the Cantor solution if developed can be a real alternative where
memory is a premium.

I can get in touch with the sage guys as well if results are positive, given
that Cantor could become cross platform in the future. Their sagenb project has
slowed a bit as they are concentrated on the cloud project. Cantor's plugin
could therefore be a way forward for desktop users en masse and cross platform.

All the best for now!

[cantor] [Bug 312738] Should import Sage LaTeX macros

[jackdyson31 via KDE Bugzilla]

https://bugs.kde.org/show_bug.cgi?id=312738

--- Comment #8 from jackdyson31  ---
@Antonio Rojas : right thanks, thats quite an old issue - it is actually
happening on Kubuntu 16.04 with the latest version of Cantor that I have access
to. 327259 affected just Sagemath. What I am saying here is the is NO LaTeX
output for Maxima or Sage and I have downloaded and built the latest one on
your repository to check before I posted this.

We might also check to remove an old bug: open more than a single session and
the menus reorganize themselves on the menubar. Kill the status bar and you
cannot type text anymore.

If there is anything I should or could do to help please say, given that I know
you guys are busy. I just need to know how to properly install as a debian
package (apt-get source doesn't work for this version).

However, in my experience, every release of Sagemath or Cantor has broken
something, which wastes time. It is a great concept but if we are serious then
we might have a discussion about ensuring basic stability of common features
(and that can also include the Sagemath people so that they don't keep changing
basic stuff).

Using version 0.6 pn Kubuntu 16.04 I can't get LaTeX rendering at all: you just
get a plain text answer:

(cot(x)^2 + 1)*x/cot(x)^2 + 1/cot(x)

I thought this is sagemath version thing again - however the plugin for maxima 
produces the same issue. All latex deps installed - cantor renders its tex
cells successfully

[cantor] [Bug 363560] Sage backend is not working with Sage 7.2 version

[jackdyson31 via KDE Bugzilla]

https://bugs.kde.org/show_bug.cgi?id=363560

--- Comment #6 from jackdyson31  ---
just for info : downloaded and built the 16.04 updated Cantor Version 16.07.70
on Kubuntu 16.04 - doesn't seem to work, opens a sage window : typing commands
hangs it or displays nothing as output.

Only solution I got running was mathcals' suggestion here:
https://bugs.kde.org/show_bug.cgi?id=348128
The LaTeX doesn't work however (it does on the old Cantor in Kubuntu 14.04)

thanks for all the hard work!

@mathc...@outlook.com

absolutely brilliant solution, should work out on other versions too - if you
have kubuntu backports installed then doing a rebuild is a nightmare. Many
thanks !

Hi Filipe,

I don't suppose something similar can be done for the 14.04 versions can there
?

my "fixes" broke the automated tex output for it ...

best,

Jack

[cantor] [Bug 312821] When using Sage Math, Cantor can't render equations entered via show() command and pops a LaTeX error instead.

--- Comment #9 from jackdyson31  ---
I have checked lines 183 of sageexpression.cpp in both the 0.5 (my current) and
0.6 versions of Cantor. The code is identical so I suspect the LaTeX might also
be broken in newer versions of Cantor. I extracted a show(x^2) output from a
sage 6.5 and a sage 7.0 notebook "worksheet.html" file:

sage 7.0:
***

{{{id=1|
show(x^2)
///
\newcommand{\Bold}[1]{\mathbf{#1}}x^{2}
}}}

{{{id=2|

///
}}}

as well as the output from sage 6.5 for the same file:

sage 6.5
***

{{{id=1|
show(x^2)
///
\newcommand{\Bold}[1]{\mathbf{#1}}x^{2}
}}}

{{{id=2|

///
}}}

and they are identical. However sage 6.5 displays ok in Cantor 0.5 but when
Cantor 0.5 runs sage 7.0, the output is as in my last post. Can anyone with
more knowledge who sees this guide me a bit ?

Thanks!

Evening Mat,

Cheers for the really great and easy to follow instructions which work like a
treat for Cantor 0.5 4.13 - I just hacked them and did the same update on
Cantor 0.5, 4.14.3 from Kubuntu Backports (anyone interested in how that
happens, get in touch with me and I'll fill you in)

No problems for the typo - just said it to help less experienced guys. One
other small thing I did:

//QRegExp versionExp("Sage\\s+Version\\s+(\\d+)\\.(\\d+)");
QRegExp versionExp("Sage(?:Math)?\\s+Version\\s+(\\d+)\\.(\\d+)");

which is different to the one proposed for the latest version of Cantor (0.6).

This fix is a bit of a life saver!

Jack

PS Having run sage 7.0, 6.10, 6.9 etc in the rebuilt version, sadly the latex
output is disabled (if you try show(x^2) for example it just dumps a string),
sage 7.0 on Cantor 0.5 is a HUGE improvement and very powerful.

Dear Matteo and Filipe,

worked like a charm :-D, sage 7 fires up like it never went out out of fashion
on Cantor 4.13

many thanks again

Jack

PS can I post the .deb somewhere for other fellows in my predicament?

PS @Matteo :
sudo apt-get install build-dep cantor --> sudo apt-get build-dep cantor
(just in case some other chap tries his hand at it)

Hi Matteo!

Thankyou so much for taking the time to sort that out so nicely. I will start
working on it as soon as get a moment. I'll post back what happens here for any
observations and results. One small thing - will the new compiled version
support both prior and post 6.5 sage additions ?

Jack
