<p>This example demonstrates the libgit2 rev walker APIs to roughly
simulate the output of <code>git log</code> and a few of command line arguments.
<code>git log</code> has many many options and this only shows a few of them.</p>
<p>This does not have:</p>
<ul>
<li>Robust error handling</li>
<li>Colorized or paginated output formatting</li>
<li>Most of the <code>git log</code> options</li>
</ul>
<p>This does have:</p>
<ul>
<li>Examples of translating command line arguments to equivalent libgit2
revwalker configuration calls</li>
<li>Simplified options to apply pathspec limits and to show basic diffs</li>
</ul>
