I apologize in advance for my somewhat rambling post. I don't have any really urgent questions; just a few small ones, along with some comments. I'm an algebraic geometer, so I use Macaulay 2 for certain things, but often I prefer Maple which has a lot more flexibility. Although I have free access to Maple through my University, I have never been entirely comfortable with this... but I suppose it's not necessary to preach to the choir. I'd heard some rumours about Sage, and I recently downloaded it to my Mac (G5, macosx 10.4). I have been playing with it for a couple of days, and I am pretty impressed. However...
In Maple I find it convenient to use "%" to refer to the output on the previous line. Is there a way to do this in Sage? If not, would this or a scheme using line numbers, be a useful feature to add? As a more serious exercise, I tried writing a script in Sage. Since I'm pretty new to Python, I have to admit that I was a bit taken aback that indentation was part of the language, but it's not a big deal. Anyway, I found that I could manage by typing things into emacs (actually aquamacs) and pasting the formatted code into the notebook, since I like to debug one function at a time. This seems a bit clumsy however. What to other people do? Surely, it must be possible to have emacs communicate directly with sage? Incidentally, the script in question computes Betti numbers for moduli spaces of vector bundles using standard formulas. I'm happy to say that it seems to be working correctly under Sage. I've checked it against values generated by my original Maple script and published values for small rank and genus. Anyway, my thanks to all for putting this package together. - Donu Arapura --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to [email protected] To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
