> oops, OK, I somehow had trouble splitting lines, and thought that the
doctests framework doesn't quite allow this. What is the syntax? Will it
just ignore '\n', anywhere ?
I think that you can more or less split where there is a space.
You can just copy what used to be done for the previous examples.
> Are you saying that this "error code"=6 is a new addition in Maxima, and
is not properly handled by the Sage interface?
I'm not sure that this is new, but:
* Sage used to return a ValueError so I guess that it used to catch a
Maxima error and translate it
* So it seems that Maxima's behavior has changed even though the "6" case
used to be there, maybe a Maxima expert could tell us why this was
decided. Anyhow, your fix might be the right one then...
A last comment, in your modification to desolve() you modify the domain
var of Maxima.
So if I use domain=real with your code, then all of Maxima will use
domain=real afterwards.
Maybe we'd better set back domain to whatever it was worth before at the
end of the computation.
