Is it possible and how "Giving credit for a change" for Mercurial/Git as in Bazaar?

Question

Bazaar support adding meta data to commit to record who the actual author of a change is vs. the person who commits the change:

  $ bzr commit --author "Jane Rey <[email protected]>" \
               --author "John Doe <[email protected]>"

After adding this meta data it accessible via bzr log, like:

It is possible embed such metadata in commit for Mercurial/Git?

Answer 1

In git you have the similar command:

git commit --author="Name <[email protected]>"

But it usually comes from pre-set config values.

Hg has a similar flag for setting the user, but does not make a distinction between author and committer. But there is an extension to do that.

Both git and hg do not have the concept of setting multiple authors for a commit. Though that is usually done in the commit message in some pre-determined way / convention in the team

Answer 2

Mercurial has no such ability by default. There is no way to specify a "committer" vs an "author" directly. Similarly there is support for only one author.
