+1 There is a logging facility now in Sage, which I mostly implemented and use. Try doing "set_verbose(2)" and doing some linear algebra (say), and you'll see a lot of messages. I wrote that logging system to basically be like Magma's. Given that Sage is thoroughly a Python project now, I would be happy with the get_verbose/set_verbose/verbose commands in Sage being rewritten to use the standard Python logging facility. I really love verbose logging options in code and software I use. This is not my highest priority right now, but I hope you'll consider making it yours. :-) William --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
