[sage-support] expression evaluation with dynamically generated variables

Hello, I need to be able to evaluate an expression, where the expression is composed of dynamically generated variables. For example, I might have a list var_list, a list data_list, and an expression exprssn. Here 1) var_list is a list of variables, where every element in var_list was created

[sage-support] Re: Minor sage 3.4/jsMath3.6b rendering issue in IE7

2009-04-25 Thread dpvc
Thanks for posting the new example. I have found that the problem is due to the fact that Sage puts the output inside a PRE block, and IE7 gets confused about some of its measurements in that case. It can be fixed by including span.typeset { white-space: normal; } in the css/main.css

I have made a patch that attempts to limit the number of snapshots that get saved (per worksheet) to an absolute maximum of 30. There's a bit of a dilemma about just how to do this, given that at present some users will have more than 30 snapshots for some worksheets, and in the future this
