[sage-devel] Fwd: Circle packing package

The package CirclePack (link below) has been recommended to me for possible inclusion in Sage. It is GPL. I have not tried it myself but if any reader is interested perhaps they would like to try it out and report back. John -- Forwarded message -- From: Edward Crane <[EMAIL PR

Fluid is indeed a great idea! I hadn't thought of it, in part because I'm still running Mac OS 10.4 until my employer authorizes 10.5. Fluid only works with 10.5. Platypus is a program that builds an app bundle for little scripts. I used it to wrap a simple bash shell wrapper for Sage, and have u

[sage-devel] Add new structures to Sage: Parent and Element

2008-02-12 Thread Franco Saliola
Hello. I'm wondering if there is some documentation or a howto somewhere that describes the process of adding new structures to Sage. For example, we want to add poset functionality to Sage---Peter Jipsen and I began working on this at Sage Days 7. So we created a Poset class that inherits from P

Oh, the "instance" that I was referring to is just the language I picked up from reading sage/libs/pari/gen.pyx: it appeared as though pari('') was shorthand for a globally defined PariInstance. The "old instance" is the one you can obtain externally from pure Python code. Is this not what is ha

So, these kinds of issues were the subject of the coercion project at SD7. Robert Bradshaw, Mike Hansen, Bobby Moretti and I are currently in the process of changing a lot of the infrastructure behind parents, elements, etc. If you want to help (or want to see our current progress) see the sprint

Hi Mike, Thanks for the explanation. Indeed a Permutation could be represented by an element of a symmetric group, but we would want to make sure that until a group-theoretic question is asked, no call to GAP should interfere with the calculations. Your: sage: G = Permutations(3) would be ana
