<p>This example demonstrates the use of the libgit2 status APIs,
particularly the <code>git_status_list</code> object, to roughly simulate the
output of running <code>git status</code>. It serves as a simple example of
using those APIs to get basic status information.</p>
<p>This does not have:</p>
<ul>
<li>Robust error handling</li>
<li>Colorized or paginated output formatting</li>
</ul>
<p>This does have:</p>
<ul>
<li>Examples of translating command line arguments to the status
options settings to mimic <code>git status</code> results.</li>
<li>A sample status formatter that matches the default &quot;long&quot; format
from <code>git status</code></li>
<li>A sample status formatter that matches the &quot;short&quot; format</li>
</ul>

<p>Run status on the repository</p>
<p>We use <code><a name="git_status_list_new-12" class="fnlink" href="../../#v0.25.1/group/status/git_status_list_new">git_status_list_new</a>()</code> to generate a list of status
information which lets us iterate over it at our
convenience and extract the data we want to show out of
each entry.</p>
<p>You can use <code><a name="git_status_foreach-10" class="fnlink" href="../../#v0.25.1/group/status/git_status_foreach">git_status_foreach</a>()</code> or
<code><a name="git_status_foreach_ext-11" class="fnlink" href="../../#v0.25.1/group/status/git_status_foreach_ext">git_status_foreach_ext</a>()</code> if you&#39;d prefer to execute a

about what results are presented.</p>
