Hi Antonio,
I saw your message about the Maxima plug-in for your wiki.
That is a very interesting idea.
Given that one cannot foresee all the conditions in which
Maxima will want to ask a question, I don't see that it's
practical to use "assume" to try to preclude all questions.
How about this. Instead of directly entering Maxima commands
in the wiki text, open a little window in which users can
interactively develop their answer, then cut and paste the
result into the wiki page. It always takes some working
with different expressions to get stuff just the way you
want it, anyway.
Incidentally
assume_pos: true$
integrate (x*log(x), x, a, a+da);
yields the expected result without asking a question.
In this case the difference, (a+da) - a = da, is a symbol.
"? assume_pos" seems to imply (it's not very clear) that only
symbols and subscripted variables are covered, not all expressions.
Hope this helps,
Robert Dodier
