Re: Listing all available functions/members

Andreas: I remember how we wrote it together at the polymake workshop in 2016. Does it still sit in some private extension?
No, all working and in master at apps/common/perllib/Jupyter.pm
The jupyter interface itself is at https://github.com/polymake/jupyter-polymake and still needs some work.

Re: Listing all available functions/members

There is a jupyter kernel for polymake using pexpect that has tab completion already implemented. This is essentially done by using the tab completion method of polymake, so that we only need very litte code and directly have the full power of polymake's tab completion. Maybe you can just reuse this...

Re: does not find singular 4.1.0

singular renamed one of their libraries (from resurces to singular_resources), and the name is spelled out in the polymake configuration. As you apparently compile polymake yourself there are two easy fixes: You can either switch to the Snapshot release of polymake on github, or you edit the file bu...

Re: Building polymake from source on Mac OS X

The compiler error should be fixed with the new version of polymake available on github.

Re: Building polymake from source on Mac OS X

Indeed, the latest command line tools (clang version 7.3) don't compile polymake, neither the released version nor the latest development version. clang 7.0 (the previous version of the clt) are fine. I currently cannot offer a solution, but I am working on it. I'll post again once this is fixed. I'...

Re: v 3.0 can't open in Mac OS X 10.11

MacOS by default quarantines all software (it detects, i.e. mostly stuff installed into /Applications) not downloaded through the app store. Normally, at first start you would get a popup stating something like that you have downloaded software from an untrusted source and your security settings don...

Re: Error message about lack of Postscript viewer

polymake asking for a postscript viewer in particular means that configuration/compilation of the java parts of polymake or the jreality viewer failed. Fixing this would certainly be the more favourable solution as jreality is an interactive viewer that allows you to scale and turn the visualized ob...

Re: polymake won't start from command line on Mac

The bundle is not intended to be started from the command line. Instead, you can drag the app from the dmg to /Applications and then start it by double clicking it in the finder (or in your preferred way to start any other Mac app). As any other Mac app, though, you can also start it from the comman...

Re: Volumes: inequalities and equations

You can start with the second code block in that reply, so define a point outside your hyperplane and add this to a new polytope together with the vertices of your original one. You can use the same point as in the example, with the correct dimension of course: polytope > $point_outside_hyperplane=n...

Re: Volumes: inequalities and equations

The volume computation in polymake is always done with respect to the ambient space. Your polytope lives inside the hyperplane H defined by the equation x1+...+x6=1, so it has at most dimension 5, and as such its six-dimensional volume is always 0. What you probably want is its "relative volume...
