$ git log --format=json
[{
    "commit": "64eabf050e315a4c7a11e0c05ca163be7cf9075e",
    "tree": "b1e977800f40bbf6de906b1fe4f2de4b4b14f0fd",
    "author": "Tux <t...@example.com> 1490981516 +0200",
    "committer": "Tux <t...@example.com> 1490981516 +0200",
    "message": "This is a test commit",
    "long_message": "This explains in more details the commit"
}]
