""" A very sharp-eyed reader will also have noticed that the previous cell had %auto at the very top, and that it was not necessary to evaluate the cell to use it. - The command %auto allows us to have a cell, especially an interactive one, all loaded up as soon as we start - particularly convenient for a classroom situation. - Such instructions are called *percent directives* . Most are documented in the notebook help one can access at the top of any worksheet """ Unfortunately, as you can see from the `lsmagics`, this "percent directive" does not exist any more. I suspect it was part of the *old* sage notebook and was not ported to the new jupyter notebooks that sagemath uses now. The fact that it's referred to as a "percent directive" instead of a cell magic (as you can see from the description, it should be a cell magic and hence be spelled with "%%" if it were something for a jupyter notebook) is also an indication. It should probably be removed from the documentation As to why it wasn't ported: it may not fit easily in the architecture of jupyter notebooks and/or there may be notebook extensions that can already do this through some other mechanism. If it were provided, it should be done on the level of the python3 Ipython kernel, of which the sagemath kernel is a derivative. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
