<pre><code>Proper Name &lt;proper@email.xx&gt; Commit Name &lt;commit@email.xx&gt;</code></pre>

</div></div>
<div class="paragraph"><p>which allows mailmap to replace both the name and the email of a
commit matching both the specified commit name and email address.</p></div>
<div class="paragraph"><p>Example 1: Your history contains commits by two authors, Jane
and Joe, whose names appear in the repository under several forms:</p></div>
<div class="listingblock">
<div class="content">
<pre><code>Joe Developer &lt;joe@example.com&gt;
Joe R. Developer &lt;joe@example.com&gt;
Jane Doe &lt;jane@example.com&gt;
Jane Doe &lt;jane@laptop.(none)&gt;
Jane D. &lt;jane@desktop.(none)&gt;</code></pre>
</div></div>
<div class="paragraph"><p>Now suppose that Joe wants his middle name initial used, and Jane
prefers her family name fully spelled out. A proper <code>.mailmap</code> file
would look like:</p></div>
<div class="listingblock">
<div class="content">
<pre><code>Jane Doe         &lt;jane@desktop.(none)&gt;
Joe R. Developer &lt;joe@example.com&gt;</code></pre>
</div></div>
<div class="paragraph"><p>Note how there is no need for an entry for <code>&lt;jane@laptop.(none)&gt;</code>, because the
real name of that author is already correct.</p></div>
<div class="paragraph"><p>Example 2: Your repository contains commits from the following
authors:</p></div>
<div class="listingblock">
<div class="content">
<pre><code>nick1 &lt;bugs@company.xx&gt;
nick2 &lt;bugs@company.xx&gt;
nick2 &lt;nick2@company.xx&gt;
santa &lt;me@company.xx&gt;
claus &lt;me@company.xx&gt;
CTO &lt;cto@coompany.xx&gt;</code></pre>
</div></div>
<div class="paragraph"><p>Then you might want a <code>.mailmap</code> file that looks like:</p></div>
<div class="listingblock">
<div class="content">
<pre><code>&lt;cto@company.xx&gt;                       &lt;cto@coompany.xx&gt;
Some Dude &lt;some@dude.xx&gt;         nick1 &lt;bugs@company.xx&gt;
Other Author &lt;other@author.xx&gt;   nick2 &lt;bugs@company.xx&gt;
Other Author &lt;other@author.xx&gt;         &lt;nick2@company.xx&gt;
Santa Claus &lt;santa.claus@northpole.xx&gt; &lt;me@company.xx&gt;</code></pre>
</div></div>
<div class="paragraph"><p>Use hash <em>#</em> for comments that are either on their own line, or after
the email address.</p></div>
