Sage-Combinat: enhancing Sage as a toolbox for computer exploration in algebraic combinatorics

Sage-Combinat is a software project whose mission is: to improve the open source mathematical system Sage as an extensible toolbox for computer exploration in (algebraic) combinatorics, and foster code sharing between researchers in this area.

In practice, Sage-combinat is a collection of branches on top of Sage, developed by a community of researchers. The intent is that most of those branches get eventually integrated into Sage as soon as they are mature enough, with a typical short life-cycle of a few weeks. In other words: just install Sage, and you will benefit from all the Sage-combinat development, except for the latest bleeding edge features.

2008-06-19: MuPAD-Combinat join forces with Sage
- Sage-combinat was born as a partial port of MuPAD-Combinat. After months of discussions and experiments, an enthusiastic consensus emerged in the MuPAD-Combinat community to join Sage. Sage-combinat henceforth became the natural successor of MuPAD-Combinat.
- The transition was a massive investment (and is not yet completely over): seven years of hard work to port over! However a lot of experience was gained since 2000, and most of the design was pretty clear, and we could *share* the work.

How to participate and contribute

Communication

Join our mailing lists:
- Announcement mailing list (to come)
- sage-combinat-devel: Developers' mailing list
- sage-combinat-commits: A low traffic mailing list which receives an automatic notice whenever a sage-combinat related ticket is modified (and eventually whenever a commit is done on the patch server).
- sage-combinat-days: Mailing list for the organisation of Sage-Combinat days
Check the road map and current status
Post bug reports, suggestions, patches on the Sage-Combinat trac server or on the mailing list.

Code

Since Sage 6.0, the development workflow has been reworked in depth, and we are in the progress of migrating the extensions as git branches. Here are some useful links:

The Sage-Combinat extensions used to be managed as a collection of patches on our patch server, using a so-called mercurial queue. Quite some stuff below is thus outdated, and will be progressively replaced by information on the new workflow.
