Le forum de XCAS

Thanks: I upgraded to 1.5.0 and the problem is gone.

I'm using xcas 1.2.3 (of Ubuntu 18.04). xcas has an autosave feature: every minute, or so, it saves the session (if changes exist in it), to "~/xcas_auto_XXXXXXXX.xws". Unfortunately, this seemingly nice feature makes life unbearable for Linux users: After autosaving, xcas moves the focus to its win...

Thanks for replying. I checked your solution. It works for 'giac' only (the console app), not for 'xcas' (the GUI app). For example, I added ";myfunc(x):=x*666;" to ~/.xcasrc. 'giac' then recognizes "myfunc", but 'xcas' doesn't. Is there a solution that works for 'xcas' as well? For reference, here'...

Is it possible to define my own functions in some file, and have it loaded automatically each time 'giac' or 'xcas' start?

I've found the cause of the problem: I googled "fltk 'right control'" and found a bug report for FLTK: Fl_Text_Editor: right control key deletes text It turns out that it's a "feature". Quite a horrific one. I wonder why I'm the only one who encounters this issue. Xcas is statically linked, so we'r...

I think it's irrelevant: it's the control key itself, not the following "C/V/X", that causes the deletion.

Thank you!

There's a problem creating tangents to ellipses and parabolas (but there's no problem with circles) when we use non-integer numbers. For example, the following code works: el := ellipse(-1,1,point(1+i)); A := point(-3+3*i); tn := tangent(el, A); But the following code doesn't work: el := ellipse(-1,...

Really strange. I just checked on my ubuntu (11, i386) and Ctrl-C/V/X work. Just to clear a possible misunderstanding: It's pressing the right control key that already deletes the selected text (its "keypress event", in technical speak). So I don't even get a chance to hit C/V/X. (When no text is s...

I'VE FOUND A SOLUTION: It turns out that only the right control key deletes the selection. The left control key doesn't delete it. So my problem is solved now. I'll just have to train myself to use the left key. (Just for the record: have you two ever tried the right control key? There's a slim chan...

I'm using xcas (insalled via the Debian/Ubuntu repository at http://www-fourier.ujf-grenoble.fr/~parisse/debian/ ), on Ubuntu. Often I want to copy text to the clipboard. So I mark some text with the mouse or keyboard and press Control-C. The problem is that when the Control key is pressed down, the...
