List all developers on a project in Git

Question

Is it possible to list all users that contributed to a project (users that have done commits) in Git?

Any additional statistics?

Answer 1

To show all users & emails, and the number of commits in the CURRENT branch:

git shortlog --summary --numbered --email

Or simply:

git shortlog -sne

To show users from all branches (not only the ones in the current branch) you have to add --all flag:

git shortlog -sne --all

Answer 2

If you want to be more specific in the list (find a list of unique committer and author), you could use git log:

git log --pretty="%an %ae%n%cn %ce" | sort -u

• %an author name
• %ae author email
• %n new line
• %cn committer name
• %ce committer email

Other placeholders are described in the pretty print documentation of git log.

Answer 3

You can try this:

git log | grep Author: | sort -u

Answer 4

(users that have done commits)

Note: by default git shortlog groups commits by authors.

If you need to group them by committers, you will need Git 2.12 (Q1 2017)

git shortlog -snc

See commit 03f4082 (16 Dec 2016) by Jeff King (peff).
See commit fbfda15 (11 Oct 2016) by Linus Torvalds (torvalds).
^{(Merged by Junio C Hamano -- gitster -- in commit ad1b4e2, 27 Dec 2016)}

Linus Torvalds himself introduces this feature:

shortlog: group by committer information

In some situations you may want to group the commits not by author, but by committer instead.

For example, when I just wanted to look up what I'm still missing from linux-next in the current merge window, I don't care so much about who wrote a patch, as what git tree it came from, which generally boils down to "who committed it".

So make git shortlog take a "-c" or "--committer" option to switch grouping to that.

Answer 5

Great answers by @pedro-nascimento, by @mic_e and others already solve the problem.

In addition, you can add the following line to your .gitconfig

contributors = shortlog -e --summary --numbered

or in shell type

git config --global alias.contributors 'shortlog -e --summary --numbered'

And after that you can simply invoke: git contributors

Answer 6

Another option can be:

git log --format='%aN' | sort -u

Answer 7

Another option is using the mergestat CLI, which is a tool that allows you to run SQL queries on git history. So a query like:

SELECT
  author_name,
  author_email count(*),
  count(*)
FROM commits
GROUP BY author_name, author_email
ORDER BY count(*) DESC

Will output a list of all commit authors in a repo, ordered by number of commits. Since it's just SQL, you can add filtering for commit timestamps, or sort by LOC added/removed, etc.

Full disclosure, I'm the maintainer/creator of the project, but wanted to share because I believe it could be useful for this type of use case.

There's also the summary command which prints out git stats by author in a repo.

I am using GHI to open issues and where I can assign issues to specific users as long as I know their usernames

I don't if this is going to be helpful for someone but I am just going to leave the solution that worked for me here:

To get only the authors username from the GitHub I ran

git shortlog -sne | grep +  | sed -e "s/.*+//; s/@.*//"

which will only list the username of the authors on the current project.

Then i can pick an username and assign an issue to him/her.

I haven't got around to testing it myself yet, but this looks really nice for project statistics for a Git repository: https://github.com/visionmedia/git-extras

Check out the bin catalog to see the the different scripts.

For example, the git-count script (commit count per committer):

git shortlog -n $@ | grep "):" | sed 's|:||'
