Git .mailmap file: Associating contributor and email aliases Merge contributers by aliases to show commit count in shortlog.
Example
When contributors add to a project from different machines or operating systems, it may happen that they use different email addresses or names for this, which will fragment contributor lists and statistics.
Running git shortlog -sn to get a list of contributors and the number of commits by them could result in the following output:
Patrick Rothfuss 871
Elizabeth Moon 762
E. Moon 184
Rothfuss, Patrick 90
This fragmentation/disassociation may be adjusted by providing a plain text file .mailmap, containing email mappings.
All names and email addresses listed in one line will be associated to the first named entity respectively.
For the example above, a mapping could look like this:
Patrick Rothfuss <[email protected]> Rothfuss, Patrick <[email protected]>
Elizabeth Moon <[email protected]> E. Moon <[email protected]>
Once this file exists in the project's root, running git shortlog -sn again will result in a condensed list:
Patrick Rothfuss 961
Elizabeth Moon 946
