The best things in Sage are 'mathematica_free'. No, no, I never would say this!


I*(log(I*e^(-e^x) + 1) - log(-I*e^(-e^x) + 1))*e^x + I*polylog(2, I*e^(-e^x)) - I*polylog(2, -I*e^(-e^x))



AttributeError: 'NoneType' object has no attribute 'groups'

I think Sage wanted to say: "Mathematica could not find a formula for your integral."
