One mapping per line, first -the author name followed by the email address enclosed by -'<' and '>'. Use hash '#' for comments. Example: +If a file `.mailmap` exists at the toplevel of the repository, +it is used to map an author email address to a canonical real name. This +can be used to coalesce together commits by the same person where their +name was spelled differently (whether with the same email address or +not). + +Each line in the file consists, in this order, of the canonical real name +of an author, whitespace, and an email address (enclosed by '<' and '>') +to map to the name. Use hash '#' for comments, either on their own line, +or after the email address. + +A canonical name may appear in more than one line, associated with +different email addresses, but it doesn't make sense for a given address +to appear more than once (if that happens, a later line overrides the +earlier ones). + +So, for example, if your history contains commits by two authors, Jane +and Joe, whose names appear in the repository under several forms: + +------------ +Joe Developer <joe@example.com> +Joe R. Developer <joe@example.com> +Jane Doe <jane@example.com> +Jane Doe <jane@laptop.(none)> +Jane D. <jane@desktop.(none)> +------------ + +Then, supposing Joe wants his middle name initial used, and Jane prefers +her family name fully spelled out, a proper `.mailmap` file would look like: ------------ -# Keep alphabetized -Adam Morrow <adam@localhost.localdomain> -Eve Jones <eve@laptop.(none)> +# Note how we don't need an entry for <jane@laptop.(none)>, because the +# real name of that author is correct already, and coalesced directly. +Jane Doe <jane@desktop.(none)> +Joe R. Developer <joe@random.com> ------------ Author |
