#2031 Operator ' does not work with integrate?

[Emilio Suarez]

%i1 'integrate(x^3+3,x,1,5);
%o1 168;

I think it shouldn't evaluate the integral. Am I wrong?

[Emilio Suarez]

Well, I test it's a conflict with the "abs_integrate.mac" package present in my maxima-init-mac. Sorry.

[Barton Willis]

Workaround:

(%i4) load(abs_integrate)$

(%i5) '(integrate(x^3+3,x,1,5));
(%o5) integrate(x^3+3,x,1,5)

I'll see if I can make abs_integrate respect the quote...

[Emilio Suarez]

Then perhaps is due to the brackets at the begining and end of the integrate. Without loading abs_integrate, it works without this brackets, but loading this package it doesn't.
Tkanks you very much

Setting the resolution back to none. The bug is still present in Maxima 5.22post.

Assign category = Share Libraries, since this is a bug in abs_integrate, not integrate.

[Barton Willis]

Due to the way abs_integrate works (tellsimpafter), there is no simple fix to the bug. Once an integral is handed off to abs_integrate, the code has no way of knowning that the expression started as a nounform. A fix would, I think, require puting a hook into the main integration evaluation code that would try additional methods. Maybe that would be a good feature for Maxima...

(%i8) load(abs_integrate)$
(%i9)  'integrate(x^3+3,x,1,5);
(%o9) 168
