GITMAILMAP(5)                  Git Manual                  GITMAILMAP(5)

NAME         top

       gitmailmap - Map author/committer names and/or E-Mail addresses

SYNOPSIS         top


DESCRIPTION         top

       If the file .mailmap exists at the toplevel of the repository, or
       at the location pointed to by the mailmap.file or mailmap.blob
       configuration options (see git-config(1)), it is used to map
       author and committer names and email addresses to canonical real
       names and email addresses.

SYNTAX         top

       The # character begins a comment to the end of line, blank lines
       are ignored.

       In the simple form, each line in the file consists of the
       canonical real name of an author, whitespace, and an email
       address used in the commit (enclosed by < and >) to map to the
       name. For example:

           Proper Name <commit@email.xx>

       The more complex forms are:

           <proper@email.xx> <commit@email.xx>

       which allows mailmap to replace only the email part of a commit,

           Proper Name <proper@email.xx> <commit@email.xx>

       which allows mailmap to replace both the name and the email of a
       commit matching the specified commit email address, and:

           Proper Name <proper@email.xx> Commit Name <commit@email.xx>

       which allows mailmap to replace both the name and the email of a
       commit matching both the specified commit name and email address.

       Both E-Mails and names are matched case-insensitively. For
       example this would also match the Commit Name <commit@email.xx>

           Proper Name <proper@email.xx> CoMmIt NaMe <CoMmIt@EmAiL.xX>

EXAMPLES         top

       Your history contains commits by two authors, Jane and Joe, whose
       names appear in the repository under several forms:

           Joe Developer <>
           Joe R. Developer <>
           Jane Doe <>
           Jane Doe <jane@laptop.(none)>
           Jane D. <jane@desktop.(none)>

       Now suppose that Joe wants his middle name initial used, and Jane
       prefers her family name fully spelled out. A .mailmap file to
       correct the names would look like:

           Joe R. Developer <>
           Jane Doe <>
           Jane Doe <jane@desktop.(none)>

       Note that there’s no need to map the name for
       <jane@laptop.(none)> to only correct the names. However, leaving
       the obviously broken <jane@laptop.(none)> and
       <jane@desktop.(none)> E-Mails as-is is usually not what you want.
       A .mailmap file which also corrects those is:

           Joe R. Developer <>
           Jane Doe <> <jane@laptop.(none)>
           Jane Doe <> <jane@desktop.(none)>

       Finally, let’s say that Joe and Jane shared an E-Mail address,
       but not a name, e.g. by having these two commits in the history
       generated by a bug reporting system. I.e. names appearing in
       history as:

           Joe <>
           Jane <>

       A full .mailmap file which also handles those cases (an addition
       of two lines to the above example) would be:

           Joe R. Developer <>
           Jane Doe <> <jane@laptop.(none)>
           Jane Doe <> <jane@desktop.(none)>
           Joe R. Developer <> Joe <>
           Jane Doe <> Jane <>
