Description (last modified by )
This ticket is a prerequisite to further development in the combinatorics of words and symbolic dynamical systems (adic language, SFT, ...). It concerns the implementation of a class "Language" (= graded set of words) as a Parent and a class "Word" as Element.
Three categories are created: Languages, FactorialLanguages and Shifts that gather several methods of finite and infinite words. For speed reason there are base Cython classes for
- finite word (in sage.combinat.words.finite_word)
- infinite word (in sage.combinat.words.infinite_word)
- language (in sage.combinat.languages.language)
Every implementation must inherit from the class above (it is check in the TestSuite? of the related categories).
The previous code of Word is dispatched between the ElementMethods of the category and the Cython class FiniteWord. The choice has been made for sake of optimization.
Old pre-git instructions to import the code. To import and apply all patches do

I started the review. Here is a first bunch of comments.
- Goal of the ticket: Categories in
sage/combinat/words
library. The goal of this patch reimplements the code structure ofsage/combinat/words
using categories. It also adds classes for languages which is a good thing that I would need for my own research. It touches other files outside of this folder. It also depends on some particular tickets fixing bugs in Cython (#13957) and other patches that apply on similar files which do not commute with this huge patch. Moreover since it is a huge patch touching many files, it prevents any user/developper to change any code insage/combinat/words
without creating conflicts. So I hope this will not take forever to get reviewed because meanwhile it prevents the evolution of the actual code.
- Content of the patch. It is a huge patch (1.3MG). It modifies 40 files, add 27 files and removes 6 files (see detailed list below). It is hard for any reviewer to make sure he doesn't miss a problem possibly added by the patch. Is there a way to cut the patch in different chunks (tickets) which could make it more easy to get it into Sage because easier for reviewers?

- Reject on tableau file. The actual path creates a reject on the tableau file (I am still using the svn directory for the patches. I will test the patch from the ticket instead soon. Maybe that's the reason for the reject.) :

- Few broken doctests. Here are some testing errors I get on the my machine as well as on sage.math. Note that I tested only
sage/combinat
folder on my machine. This shows that some doctest are machine dependant (32bit vs 64 bits, ordering of string and int which depends on the machine : 'a'<9 vs 'a'>9 for cmp). Also for one of the doctest,352
can be replaced by...
to avoid future problem with lines added before. More precisely,

- Testing the sage-main files. I am interested in knowing whether my own code will continue to work after this ticket get merged. Eventually, I will test my own code during this review. But for now I did only one test : I check whether the doctests defined in the
sage-main
branchsage-5.6.rc0
still pass or not. I get 618 failures only forfinite_word.py
file. Some of them are__repr__
modifications that I can accept. But there are a lots of methods that do not exist anymore (maybe it is easy to fix?).

5 (second bis). Still to understand if my code will still work after this ticket, I tested the doctests of the sage-main of sage-5.6-rc1 when applying the following 8 patches on sage-5.6.rc1.

It appears that a lot of doctests are failing. The complete log is here.
One observation is that the __repr__
and __str__
should not be changed in this ticket to help the reviewer. There is enough doctests failing already...

For what reason each of these tests are failing? If it is because of a string repr that changed, this should be reverted and postpone in another ticket. If it is some hidden method starting with an underscore that was change : ok. If some result of type(something)
changed because the class name has changed : ok. But if it is a normal method, it should still work after the ticket.
