[kde-edu]: Moving libscience back to Kalzium

Moin

I am thinking about moving all of libscience back to 
kdeedu/kalzium/libscience/ so that I am able to break the API as often as I 
want. Would somebody oppose to this?

[kde-edu]: Plasma engine or applets depending on stuff in kdeedu

Moin

Plasma-engines depend on Plasma (and thus on kdebase):

     class ChemicalDataEngine : public Plasma::DataEngine

My engine also depends on libscience (in libkdeedu). As we don't have a module 
like "libkdeedu" (as in "kdepimlibs") I can't just check for it in CMake. 
Therefor I would (when the plasmoid is outside of kdeedu) depend on the whole 
kdeedu-module or somehow create a "findlibkdeedu.cmake" file in case the 
distribution installs libkdeedu seperatly. 

The other way around (the Plasma stuff being inside kdeedu) kdeedu would 
depend on kdebase which is equally stupid.

Actually, I don't see how they (applet and engine) belong to kdeedu (beside 
the technical dependency on libscience). 
Ok, given I will place the code somewhere in kdeextragear or something, it 
might be easiest for me to simply have a local copy of libscience.

Comments/Ideas?

Carsten

Perhaps I should be a bit more clear about my motives:

I plan to break the API in libscience in the future (but _after_ KDE 4.0.0 is 
out). This is not allowed in libs, of course. So when I do not move 
libscience now I will not change the API until KDE 5.0 is out.
I cannot break the API right now because of time-constrains. So for me there 
are two possible ways:

a) do nothing
b) move libscience now and change/improve it in a few month

Only Kalzium is using libscience so in effect, nothing changes when I am 
moving libscience now.

I think this only applies to kdelibs and kdepimlibs, i.e. official public 
libraries.
AFAIK it does not apply to module libraries.

Cheers,

Oh, if that is true my moving plans just became obsolete, of course.

I am pretty sure, but you should probably check with kde-core-devel for 
certainty.

Cheers.

I think i can help here. I think i could design a data structure to contain 
the expressions we are dealing with, and the ways to operate it. I can't code 
in C++, but i think i could do it in python.

Another idea would be to use the core of a free computer algebra system, such 
as Maxima or Axiom. Maybe it is ot a good idea to add such a dependency, but 
in the other hand we would get rid of this part of the problem ;).

[kde-edu]: Presentation

Hi,

I have som slides for a presentation of some kde-edu programs. It's in 
catalan. If some one is interested in, it is at 
www.eltercer.cat/kde/edu-jpl.kpr

Thanks a lot! I added a page on the KDE-Edu website where I put your slideshow 
and mine in French which I did in June.
See
http://edu.kde.org/presentations/
Best regards and thanks for sharing your presentation,

Anne-Marie
