Why does implicit multiplication not work in the Sage Cell Server?

Hello, Sage Community!

Is there any reason for implicit_multiplication(True) not having any effect in SageCell? Is there any way of solving this?

Thanks in advance for your answers!

I think this is not specific to SageCell. It is the same in jupyter. implicit_multiplication changes the behaviour of the preparser, but the whole cell is preparsed according to the previous state of the preparser.

If, in a single cell, you write:


You will get an error. But if you put the two lines in different cells, then it will work.

To take another example, you can do:


You will get <class 'sage.rings.integer.Integer'> because the whole cell was preparsed before the preparser is turned off. If you put the two lines in two different cells, you will get <class 'int'>, because the second line will not be preparsed anymore.

About the Sage preparser, see

The sagecell works like a single jupyter cell.

Hello, @tmonteil! I see. Is there any possible tweak for using implicit multiplication in Sage Cell? Or is this a definitive unavoidable behavior?

I doubt there is an easy way without modifying sagecell (or running your own).
