 Re: [Reduce-algebra-developers] TeleREDUCE From: Kurt Pagani - 2015-08-20 17:26:45 I've once compiled csl/reduce with emscripten (https://github.com/kripken/emscripten/wiki) to Javascript. It's really simple and using npm, node-webkit (now NW.js) you can create your personal gui for the modern browsers (including mathjax) or standalone. Unfortunately I lost the hg repo/makefile, however, as said, it's not difficult to do the changes necesssary.

 [Reduce-algebra-developers] A different problem with PSL version From: Alan Barnes - 2015-08-20 16:23:41 Further to my previous message: actually the current PSL version frequently fails on floating point computations with error messages of the form: ***** Undefined function safe!-fp!-quot' called from compiled code This is, I think, unrelated to the previously reported problem with redlog and has been present in the PSL version (only) for a few recent subversions.

 [Reduce-algebra-developers] Problem compiling latest CSL subversion 3184 From: Alan Barnes - 2015-08-20 16:03:53 The compilation of the CSL version fails with the error message: make[3]: *** No rule to make target /home/alan/reduce-algebra-code/csl/cslbase/../../packages/redlog/ofsf/ofsfvs.red', needed by /home/alan/reduce-algebra-code/csl/cslbase/../../cslbuild/generated-c/make.stamp'.

 Re: [Reduce-algebra-developers] TeleREDUCE From: Arthur Norman - 2015-08-20 14:54:05 ./configure --with-csl --without-gui will need adapting for --host= cross compilation but if there is a standard C library available it should work. There are bound to be a few things that will need fixing, but with luck nothing serious. The "embedded" stuff is basically the code of CSL hacked a bit to comment out those places where it might hve tried to use library facilities that could be problems, and with use of autoconf replaced by an assumption that all you need is there already. It can thus be used as part of a feasibility demonstration.... but if the "real" version could be made to work that would feel much safer as regards support. For dubious places that might be system-specific see mostly sysfwin.c Again I can not really look until I m home (and then until I have caught up a bit!). I have never build android native code before, do not know how to link the C and Java bits and hardly ever done any Android stuff in Java so any framework you could provide me with to help get me going would enhance the chances of me getting involved!

Hence use of Jlisp which can exist for just such cases! Arthur Native C code can work on Android (and probably is more efficient); bionic is a sufficiently standard libc. Android interface can live in a separate process and be written in Java. This is exactly what's done in maxima on android: there's ecl (embeddable common lisp, written in C) running maxima, and there's a 1000-lines Java gui code. This might be more efficient on a slow processor. This is why I'm asking. Does csl (with gui configured out) need any libraries beyond libc? Andrey

Arthur Norman You can try maxima on android https://play.google.com/store/apps/details?id=jp.yhonda Its user interface is not too bad, even on my 5.5" phone.

 Re: [Reduce-algebra-developers] TeleREDUCE From: Arthur Norman - 2015-08-20 12:00:04 Great and many thanks. Am at present in Sumatra not looking at tigers but in a park that is one of the few remainining places they exist here. back in a week or so (but may have a big backlog to work on). The Akra android port (I am REALLY glad somebody picked it up!) uses "jlisp" and I am part way through significant rework of that which I HOPE will at least double the speed of Reduce atop it. Maybe by Christmas... Would be nice to build a small group keen on support for algebra on tablet-class devices to work out how the user interface might really best happen and how to adapt to varying screen sizes! Will investigate some time. Meanwhile have flat faced cats and slow loris to look for!

 Re: [Reduce-algebra-developers] TeleREDUCE From: René Grognard - 2015-08-20 09:42:04 Attachments: Message as HTML Well I've been using occasionally Reduce on a Bauhn Android 10.1" Tablet. It came in two versions: one with a standard virtual keyboard and the other a special virtual keyboard for reduce but without documentation the latter is a "try & fail or win" kind of game although it seems like a very elegant solution! I found the output also very elegant on that tablet but it is huge compared to a smart phone! So far I used Reduce on that tablet mainly to while away time in waiting rooms but if the Android versions were further supported and fully documented somewhere I guess that I would use them more and for more useful purposes.

 [Reduce-algebra-developers] TeleREDUCE From: Dr. Wolfgang Lindner - 2015-08-19 19:58:49 Attachments: RED-intro.pdf Dear Enric, there is a revised new version 2014/15 of the free/open CAS REDUCE 3.8 available, please visit http://www.reduce-algebra.com/ or directly http://reduce-algebra.sourceforge.net/ It is the pioniering and very engaged work of Prof. Anthony C. Hearn, Prof. Arthur C Norman, Dr. Rainer Schöpf et al., who all have created a wonderful piece of software. Attached is a small intro for your first impression, the handbook has ca. 800 pages ;) REDUCE is a very compact and flexible CAS with an interesting rule system . It comes with many packages e.g. for mathematicans and (e.g. high energy) physics. It runs on many OS. I run it on Windows XP without any problems. There is an app named "iCAS" running REDUCE on my iPad. (approx. 10 EUR?). But there is no app for REDUCE for android AFAIK. So it might be a very good enhancement for your TeleMath suite to give access to REDUCE on smartphones/tablets as 'teleREDUCE' on your page http://telemath.altervista.org/ Please think about it, if it is some news for you. best Wolfgang -- Dr. Wolfgang Lindner Leichlingen, Germany

 Re: [Reduce-algebra-developers] Question about embedded Reduce. From: acn1 - 2015-08-19 01:33:45 Attachments: Message as HTML I am away in the wilds for another week. Email me direct in 1 week. The "embedded" stuff is a not very supported kit for people who want to use reduce as a component in their own code to do algebra for them. It is then the job of the person doing that to do basically EVERYTHING they need. They are probably going to cut down reduce to support just what they need so "limitations" are what they choose to apply. In many respects I would welcome it if we could discuss whether mathjax would interface to the widgets stuff I was working on - but only after I have spent proper time reading and rereading licensing terms... about which I tend to be neurotic.  Arthur -------- Original message -------- From: abpetrov Date: 19/08/2015 02:03 (GMT+07:00) To: reduce-algebra-developers@...

Everything looks okay here. I restarted and used: in "/home/rrogers/tmp/red-test.red"; and that also work for subsequent phi_dist_50_50 TeXmacs: 1.99.2 reduce compiled fresh on 7/3/2015 Ubuntu trusty 14.04 Fox hung on file input red-test.txt but seemed to work on the same file name as red-test.red; with little tiny output font. I had print problems trying to get print output; fox crashed. But I can do screen shots. I have heard of this before so I don't think it's your program.

 [Reduce-algebra-developers] a problem with Redlog and the GUIs From: Kostas Oikonomou - 2015-07-30 22:27:50 Attachments: Message as HTML I have been playing around with Redlog for a little while. Very impressive system. I ran one example, GDistribLaw, taken from the Redlog website. Here is the code: ------------------------------------------------------------------------ % Generalized Boolean Law of Distributivity (benchmark). load redlog; rlset ibalp; % Some code for creating the instances of the benchmark. You might % wish to switch on the compiler. procedure dist1(n); rlall(a=1 and (for i := 1 : n mkor mkid(b,i)=1) equiv for i := 1 : n mkor (a=1 and mkid(b,i)=1)); procedure dist(m,n); (for j := 1 : m mkand mkid(a,j)=1 or for i := 1 : n mkand mkid(b,i)=1) equiv for j := 1 : m mkand for i := 1 : n mkand (mkid(a,j)=1 or mkid(b,i)=1); procedure benchdist(m,n); rlall dist(m,n); % For instance, phi_dist_50_50 % K.O. changed this from (50,50) to (3,3) to make the output manageable phi_dist_50_50 := benchdist(3,3); % and commented out the next line % rlqe phi_dist_50_50; end; % of file ------------------------------------------------------------------------ Now when you run this in the FOX gui or in TeXmacs, the output looks fine. But if you type phi_dist_50_50 on the next command line, the display has a problem: at the end of the line above the <-> you see "===" instead of "b1 = 1 and b2 = 1 and b3 = 1". Since this happens with both the FOX gui and with TeXmacs, I'm hoping there is a single fix. Kostas 
 Re: [Reduce-algebra-developers] Concerning psl From: Rainer Schöpf - 2015-07-23 06:35:57 Hello Mohammad, Thomas Sturm redirected your request. First of all, please send all mails concerning Reduce to the developer mailing list at reduce-algebra-developers@... Second, it is very strange that the build process should try to access the old downloads at http://www.zib.de. I suspect you are building from an out-of-date version of the sources. Are you sure that you are correctly following the build instructions at http://reduce-algebra.sourceforge.net/downloading.html In particular, is your svn repository URL correct: http://svn.code.sf.net/p/reduce-algebra/code/trunk After running "svn co" or "svn up" the current revision nummber must be 3160. If the number is smaller, your copy is out of date. Rainer 
 Re: [Reduce-algebra-developers] reduce-algebra svn repository From: René Grognard - 2015-07-22 08:40:38 Attachments: Message as HTML Thanks! I already figured that out by trying to contact another sourceforge repository. I fact my mail bounced back but I could not stop it to be sent again automatically. So since you got it and replied the site might be on line again. Thanks for taking the trouble to reply! René.
