Description
Currently, to add gcd functionality for a new polynomial ring, one needs to add a specialized subclass of PolynomialElement
.
The attached patch allows rings to provide a _gcd_univariate_polynomial
method which will be called by PolynomialElement
to compute gcds.
This is similar to #10635.

I want to remove
self
from the docstrings.
Is this part of some style recommendation? I would say referring to self
in the docstring is perfectly acceptable, since there is an object called self
and it is usually clear what kind of object it is. Personally, I strongly prefer self
over constructions like "this element".

I agree with pbruin on self
versus this polynomial
. I find the documentation clearer with self
, and this seems to be more consistent with the rest of Sage.
Tell me what do you think of this, I'll positive review the ticket then.

Both approaches have their drawbacks. self
makes it harder to read if you do not know about python, i.e., if a 'user' consults the help. 'this polynomial' makes things slightly more difficult to understand if you know about self
.
I have been asked on different tickets to replace self
with something more appropriate. Sage is not really consistent with this.
Tell me what do you think of this, I'll positive review the ticket then. All tests passed with the current commits.
I do not really care how we do this in sage. Either way is fine with me.

I actually haven't a strong case for or against any of both solutions. I could have set it to positive review earlier, so let me do it now!
