Re: [sage-support] Re: SAGE and .NET interoperability.
Very interesting discussion--I'm glad to see stuff is still happening on this front, and great to hear from you again Blair.

There is little chance that these parts would be ported to Windows natively (on the other hand, e.g., GAP has a Cygwin port, that is well-supported etc). I toyed with making a native port of GAP to Windows some ten years ago. It was a highly non-trivial task that would have taken me months back then (and then I was relatively well-versed in Windows programming). So a "native" port of Sage would still settle for Cygwin ports of some of its modules. That was why thought such a port would take 10-30 man years. William and I disagree over what is a 'native' application, but as he said, the lawyers can argue that one out. It helps that Sage's primary front end is a web interface, in a "native Windows" browser--as long as the back end runs smoothly and out of sight the user won't notice how it works. As for those that preferrer the command line, they'd probably be just as happy in a Cygwin shell or VM (if they choose Windows at all). I'm more hopeful about the Sage Python classes--Python and Cython are both supported on Windows, and distutils is supposed to handle all the linking stuff. I'm not saying there won't be issues though--from what I've seen of it the path to a Windows port is littered with so many tools and solutions that, in theory, should Just Work (cygwin, colinux, virtualization, ...) but in practice just don't. - Robert -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org

Looking However, there is an Octave interface, including through the Notebook, which works fine assuming one has Octave in one's path. There have been a number of posts over years about Octave, and I guess there are several reasons it is not included - perhaps duplication with Scipy, and the excellent self-contained nature of Octave itself. Hope this helps. - kcrisman -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org

This is a > limitation for me. Indeed, Octave [1] is not yet a standard package of Sage. Looking through the list of optional [2] and experimental packages [3], I don't see Octave either. However, what you can do is request that Octave be added as either an experimental package or as an optional package. The barrier for being a standard package is much higher than those for being an optional or experimental package.
