<delurking> Hello everyone, I've followed this mailing list for several month. I am a math/computer science intructor (high school level). I have just written the first version of a zope product called Eduml which is an extension of an existing product called ZWiki. (everything is GPL) This package allows anyone to quickly include python, including PIL (python imaging library) , SQL queries, gnuplot commands, and LaTeX instructions in what appears to be a plain old web page (and oh yes, we can include HTML too but not directly inside the eduml elements) for example, <h1>a simple example</h1> <python> A = randint(0,9) B = randint(0,9) </python> <math> simplify $$ \A \over \B $$ </math> <sql> select * from lessons </sql> <draw> line ((0,0,100,100)) ellipse ((0,0,50,50)) </draw> <plot> sin(x) </plot> I've posted a showcase/sandbox area on http://ess.vancouver.bc.ca/zope/bruno/eduml Thanks, Bruno p.s. the new elements are part of an XML for education project I've been involved with for 2 years called EDUml (Educational Markup Language) but that is another story. </delurking> --
