This is a GitHub mirror of the development repository of the Sage library, which is the central Python/Cython foundation of the Sage distribution of mathematical software. It is normally found in $SAGE_ROOT/devel/sage-main in an installed copy of Sage.

Development

First, you must install Sage.

Where $SAGE_ROOT denotes the directory where you have unpacked and/or built Sage, replace the symlink $SAGE_ROOT/devel/sage with one pointing to your local clone of this repository. (Note: Unfortunately Sage currently expects the symlink to point to a directory whose path starts with $SAGE_ROOT/devel/sage-, so for now please make sure your local clone is in the appropriate directory and has an appropriate name.) Be aware that this repository is not the entirety of Sage; checking out old versions of the Sage library here is not sufficient to produce a vanilla old version of Sage, since you will still have newer components in other parts of the Sage system.

When working on this repository, base your topic branches on the master branch. Don't submit pull requests (unless you want to modify this README!), as this GitHub repository is only a mirror for now. Instead, post patches to trac, along with a link to your topic branch on GitHub, when you're ready for your code to be reviewed. You will need an account on trac in order to do this.

Your patches should be in Mercurial hg export format. There is a tool which can convert git format-patch output to this format, available on GitHub at kini/patch-converter.

For development advice not specific to GitHub or this repository, see the Sage Developer's Guide. Please also come to the sage-devel mailing list and talk to us about what you are doing or want to do! We may be able to save you a lot of time if you are new to hacking on Sage.

Branches

The branches I am maintaining on this repository are as follows.

release
This branch tracks the tip of the Mercurial repository distributed with the latest stable release version of Sage.
master
This branch tracks the tip of the Mercurial repository distributed with the latest development version or release version of Sage, whichever is newer. Please base topic branches on this branch if you intend to submit patches (Sage does not currently use GitHub or even git for that matter, so submitting pull requests will get you nowhere, unfortunately.)
prerelease-x.x.x.x
These branches track the tips of the Mercurial repositories distributed with various development versions of Sage. Only full release versions actually get merged into master, so these branches are kept around for your convenience (for example if you want to rebase a topic branch from one of these prerelease branches onto the current master branch).
github-master
The default branch for this GitHub repository. It should consist of master plus this README file.

Note that of the above, only release is really suitable for remote tracking, because due to the way that release management of Sage is currently done, master will jump around the DAG, prerelease-x.x.x.x will never be updated, and github-master will be rebased in order to avoid depending upon prerelease-x.x.x.x branches. Nevertheless, please base topic branches on master, not release, and rebase as necessary.
