git-lg

git-lg is like git log but with structured output.

If the binary is in your path you can run simply run git lg as git will automatically pick it up as a subcommand. Use the GIT_DIR=/path/to/.git env to control which repo to use.

While one could use git log pretty formatting like git log --pretty=format='%an,aI,%s', parsing the output can be cumbersome, possibly having to deal with illegal sequences. This tool aims to be a thin layer to allow easy parsing with other tools like jq: https://stedolan.github.io/jq/.

Currently the only output format is an array of commit objects, with only the following fields:

[
  {
    "author_name": "kennytm",
    "author_date": "2019-02-05T15:29:17",
    "committer_name": "GitHub",
    "committer_date": "2019-02-05T15:29:17",
    "subject": "Rollup merge of #58169 - boringcactus:patch-1, r=alexcrichton",
    "body": "\nUpdate contributor name in .mailmap\n\nfollowing up on email correspondence with @steveklabnik\n"
  }
]

Example:

$ git clone https://github.com/rust-lang/rust /tmp/rust
$ export GIT_DIR=/tmp/rust/.git
$ git lg | jq -r '.[].author_name' | sort | uniq -c | sort -nrk1 | head

   4791 Alex Crichton
