Get only the content of each commit in a json ? ( git diff json)

json git github git-commit

There is a couple of Gists adding support of log2json command to git:

https://gist.github.com/textarcana/1306223#file-git-log2json-sh - the original log2json command implementation
https://gist.github.com/dmegorov/b64dcea2eed31e02c916fc6ed9111f4f#file-git-log2json-sh - my version of the above with support of --name-only parameter
