I'm having some trouble trying to use the debugger in Xcas (1.9.0) on macOS (15.2), the buttons do not seem to work. I try the example in the HTML help: sumprod(a,b):={ local s,p; s:=a+b; p:=a*b; return [s,p]; }; debug(sumprod(2,3)) I press the 'sst' and 'in' buttons, but the program does not advanc...

I've tried with the xcas_mac.dmg version and the same behavior occurs for me.

In both versions a right (two finger) click seems to work fine, the template is filled in with the example values. It is just the left click that seems not to work for some reason..

I'm using xcas 1.9.0 (up to date source) compiled on macOS (15.2).

I just tried again to confirm: I highlight the 'sin(0)' example from sin, I do a left (single finger) click, and only 's' appears in the command line.

Hello, when you hover over an example of a command in the Help Index (ex: sin), the tooltip says a left click will copy the example to the command line. However doing a left click actually only copies the first letter of the example to the command line instead of the entire example. Would it be poss...

Thanks for resolving the clipping messages. I just checked, and the vector freeze still occurs.

That seems to resolve the crash on my side.

Attempting to assign a second value to a table causes a crash In the terminal is this message:

libc++abi: terminating due to uncaught exception of type std::__1::bad_function_call: std::exception

That did resolve the crash, and the correct result is returned.

This integral crashes my Xcas int((ln(x^4+1))/x^4,x,-(inf),inf)

The expected result is 2*π*sqrt(2)/3

The result can be obtained by partitioning the integral at the discontinuity x=0, evaluating the partitions using integration by parts, and taking the limit at the end points.

Thanks, it is working now. There were some additional aliases to remove and add. cd /Applications/usr/bin rm -rf doc rm -rf en_cas_help rm -rf es_cas_help rm -rf fr_cas_help rm -rf giac ln -sf ../share/giac/doc ln -sf ../share/giac/aide_cas ln -sf ../share/giac/examples Perhaps a change can be made ...

I'm still having an issue. I've done brew install hevea. I've tried to: 1. Rerun the original compile script 2. Insert ./configure --prefix=/Applications/usr make before sh mkosx in the script. 3. Do make install instead of make. The end result is that there are no entries in the Help Index, and the...

I don't have access to a windows computer at the moment, however if I can get a windows report I'll share it here.

I figured the messages weren't the issue (because they do not occur only in this case), but it would be nice if that could also be addressed if you get a chance.

In Xcas (1.9.0 on macOS): With enough items in the history to scroll, scrolling can cause the history to become distorted. A clear image can be shown again if you resize the Xcas window. If requested, I can try to upload an image of the issue or video recreating the issue. This is currently one of t...

A few more details for when you can get to it: Maybe crash was the wrong word, hang might be more accurate. The application needs to be quit and relaunched to regain control. Some messages appear in the terminal, but they always seem to appear for 3d plots so it may not be an issue: fl_push_clip: cl...

I found an easily reproducible crash (Xcas 1.9.0 compiled on macOS)

Execute vector(1,0,0)

Then press down on the keyboard until the vector exits the box.

Observe: crash

Hopefully an easy fix
