I see that github records the commit, add, and delete history for each contributor. You can check it on the graph tab.
However, it's not as granular as I would like.
Is it possible to get this information on the command line?
I'd like to save a more granular dataset in the form of a table.
What I'm thinking of is four arrays: Day/Date, Commits, Additions, Deletions
You can start with using the GitHub Statistics API like:
Get contributors list with additions, deletions, and commit counts
It does return:
total
The Total number of commits authored by the contributor.
And: Weekly Hash (weeks array):
w - Start of the week, given as a Unix timestamp.
a - Number of additions
d - Number of deletions
c - Number of commits
For the command-line aspect, use curl.
See "A curl tutorial using GitHub's API "
The above was based on the tag "github", but yes, git itself can generate stats (even fancy ones like the git-stats project)
See this gist for instance, or use git log --stat, git diff --stat.
As seen here, some form of processing is needed, to use the result of a
git log --author=$USER --shortstat $BRANCH
