Description (last modified by )
branch for this ticket: u/egunawan/16310snake82 (currently at Sage 8.2 master)
Enhancement to the cluster_algebra_quiver package: User can define a cluster algebra seed by entering a cluster triangulation class T of a surface. User can then compute the Texpansion of an arc or loop gamma by entering the arcs of T that gamma crosses.
The algorithm used is the perfect matching formula from the following papers: "Positivity for cluster algebras from surfaces" http://arxiv.org/abs/0906.0748 (section 4). "Bases for cluster algebras from surfaces" http://arxiv.org/abs/1110.4364 (section 3).

Hello,
I just had a quick look. Some remarks:
 every line with
EXAMPLES::
(or ending with::
) must be followed by an empty line
 try no to use comments (with #) in the doc. You can just make sentences.
 do not put space after the name of a function:
def mything(myarg):
and not
def mything (myarg):

you should not use if something == True
and if something != True
but rather just if something
and if not something
comment:9 Changed 4 years ago by
Same thing for None
. One should use if something is None
or if not(something is None)
rather than == None
and != None
Also please avoid using ;
: rather separate the commands on several lines
And last but not least, every single function must be doctested:

When I run "./sage docbuild reference/combinat html" I get errors and I have not been able to figure out how to fix them.
When pushing to trac, I did "git push setupstream trac HEAD:u/egunawan/ticket/16310". Was this the correct command?
comment:14 Changed 4 years ago by
Ok, I am currently cleaning the doc so that it will build.
The main point is that you did something like that (many times)
EXAMPLES:: Here is my favorite example:: sage: 1 + 1 == 3
where it should be instead
EXAMPLES: Here is my favorite example:: sage: 1 + 1 == 3
One other important point is that reference should be only given *once* in all the sage library. You should not duplicate the same reference in distinct files. Sage is able to find them in any place, so you can use citations from references in any other file.

Hello,
I have made a branch public/ticket/16310
based on u/egunawan/ticket/16310
on top of sage 6.5.rc3
If you were working with sage 6.4.1, you should before go to 6.5.rc3 or later. You can then pull this branch using git pull public/ticket/16310
Doc now builds. I have tried not to touch the code, but could not completely stop myself to do that. I should not have broken anything, but please check that it still works.

comment:17 followup: ↓ 18 Changed 4 years ago by
Thank you for fixing my code!
Question 1: The two failing doctests above happen in Version 6.5.rc2 but all tests (in cluster_algebra_quiver folder) pass in Version 6.5.rc3.
list.sort() method behaves differently in Version 6.5.rc2 and Version 6.5.rc3. Should I change my doctests so that my doctests do not depend on the behavior of list.sort()?
Sage Version 6.5.rc3 and Version 6.4: sage: li = [1,2,3,'r','ell'] sage: li.sort() sage: li ['ell', 'r', 1, 2, 3]
=============
Sage Version 6.5.rc2: sage: li = [1,2,3,'r','ell'] sage: li.sort() sage: li [1, 2, 3, 'ell', 'r']
Question 2: In the future, when I need to push new commits to the public branch "public/ticket/16310", do I type "git push setupstream trac HEAD:public/ticket/16310" or do I need to do something different?
In several months, we would like to enhance this code so that user can work with a surface cluster algebra *with principal coefficients*. Do we create a new ticket and branch or continue with this ticket?

Replying to egunawan:
Thank you for fixing my code!
My pleasure.

Well, all tests must pass in the most recent version.
It seems very strange to use lists that mix integers and letters. Is this really what you use in the code ? Could you try to avoid that ?
Question 2: In the future, when I need to push new commits to the public branch "public/ticket/16310", do I type "git push setupstream trac HEAD:public/ticket/16310" or do I need to do something different?
The setupstream is a convenience, not a necessity. You can just use
"git push trac HEAD:public/ticket/16310"
But in fact, it is not necessary that you work with the public/ticket/16310
branch
Instead I think that you can do that:
1) git checkout "your local name for the branch u/egunawan/ticket/16310" So you are "sitting on your branch" 2) git pull trac public/ticket/16310 So you have included "public/ticket/16310" in your branch 3) then you can just use "git push trac HEAD:u/egunawan/ticket/16310" as before to push into trac under that name 4) you can put back "u/egunawan/ticket/16310" in the branch field of trac
But I am not a git wizard, so be careful..
I suggest you click on the "commits" links at right of the Branch field (above here) to see what happens to the various branches : they coexist. Currently yours is behind public, but it can very well go back to leading position, if you do what I suggest.
In several months, we would like to enhance this code so that user can work with a surface cluster algebra *with principal coefficients*. Do we create a new ticket and branch or continue with this ticket?
Well, it depends on your priorities. In my opinion, there is still some work to be done here before this can enter SageMath. Adding another layer of complexity can only make things take longer. So I would suggest to make another ticket, depending on this one.

comment:27 Changed 4 years ago by
Thanks for the comment. I changed the status to needs_work because we will do a mathematical review first before it's ready for review.
Whenever there is a new beta in the develop branch (for example, currently 6.6 beta 5) should I merge this ticket branch into the latest beta, and how? If someone pulls this ticket branch on top of the latest sage (6.6 beta 5), will it work OK?
comment:28 Changed 4 years ago by
You should probably rebase before you ask for a review ; it's explained in the sage developer's guide.
That will show you if your code conflicts with what is now in sage, and allow you to fix the discrepancies.

Also allow ClusterTriangulation.mutate method to mutate a selffolded triangle's radius r. This mutation method is not quite an involution because it you mutate r twice you will end up with the same (unlabeled) triangulation but the label of r and the loop are switched.
