Fwrap has moved to github

From mercurial to git

After speaking with some folks at SciPy-Austin this year (in particular, Fernando Perez), I wanted to try out git & github as an alternative to mercurial & bitbucket.  As with anything with so much overlap, there are pros and there are cons, and it comes down to small differences.  The deciding factor, ultimately, was the hg-git mercurial plugin, which allows someone to use a mercurial client with a git repository, with improved branch functionality.  So all of the nice, smooth, user-friendly mercurial commands you’re used to are available, and you can push/pull bookmarks a-la git branches.  (I’ve not used this extensively, so caveat emptor.)

Some of my reasons for the move:

  • As mentioned above, the hg-git plugin allows both mercurial and git users to collaborate using the same repository, so there is no need for current mercurial users to have to change to git.
  • The numpy/scipy ecosystem is converging on git & github for SCM.  Arguably Cython (which uses mercurial) would be more influential here, but pretty much every fwrap user would be coming from a numerical & Fortran background, which would be more numpy/scipy-centric, hence git & github.
  • The way Git handles branches fits my style much better.  And I really like the index.  Mercurial seems to encourage enabling the ‘queue’ extension for advanced stuff, but it just plain doesn’t fit my brain, and I always screw it up.  Granted, it’s plenty easy to blow off your hand using git, although I’ve become quite proficient at messing up whatever SCM I’m using at the time.
  • It seems that mercurial goes to great lengths to keep their design pure, which I can respect.  Unfortunately by not allowing bookmarks to be pushed/pulled as part of the wire protocol, they force you to use mercurial branches, which are much heavier than I need them to be.  If mercurial would just allow bookmarks (which are the closest analogue to git branches) to be pushed-pulled, I’d have a much harder time justifying the switch to git.
