|
<p>Here is one from many way to use <a href="http://git-scm.org" title="Git">Git</a>. This method is sufficient to work on a project. Not there is many other <em>workflows</em>.</p>
|
|
|
|
<h2 id="basic-usage">Basic usage</h2>
|
|
|
|
<p>Work with <a href="http://git-scm.org" title="Git">Git</a> immediately:</p>
|
|
|
|
<ul>
|
|
<li>Get modification done by others <span class="black"><code>git pull</code></span>,</li>
|
|
<li>See details of these modifications <span class="black"><code>git log</code></span>,</li>
|
|
<li>Many times:
|
|
<ul>
|
|
<li><em>Make an atomic modification</em></li>
|
|
<li>Verify details of this modification: <span class="black"><code>git status</code></span> and <span class="black"><code>git diff</code></span>,</li>
|
|
<li>Add some file to be versionned if necessary:<br /><span class="black"><code>git add [file]</code></span>,</li>
|
|
<li>Save you modifications <br /><span class="black"><code>git commit -a -m "message"</code></span>,</li>
|
|
<li>Send your modifications to others: <span class="black"><code>git push</code></span> (redo a <code>git pull</code> if push return an error).</li>
|
|
</ul>
|
|
</li>
|
|
</ul>
|
|
|
|
<p>With these few commands you can use <a href="http://git-scm.org" title="Git">Git</a>. Even if it is sufficient, you need to know one more thing before really begin ; How to manage <em>conflicts</em>.</p>
|
|
|
|
<h3 id="conflicts-management">Conflicts management</h3>
|
|
|
|
<p>Conflicts can arise when you change the same line of code on the same file from another branch you’re merging. It can seems a bit intimidating, but with <a href="http://git-scm.org" title="Git">Git</a> this kind of thing is really simple to handle.</p>
|
|
|
|
<h4 id="example">example</h4>
|
|
|
|
<p>You start from the following file</p>
|
|
|
|
<div style="width: 18em; margin-left: auto; margin-right: auto">
|
|
|
|
|
|
<pre><code class="zsh">Zoot
|
|
</code></pre>
|
|
|
|
|
|
</div>
|
|
|
|
<p>and you modify one line</p>
|
|
|
|
<div style="width: 18em; margin-left: auto; margin-right: auto">
|
|
<pre class="twilight">
|
|
Zoot <span class="Constant"><strong>the pure</strong></span>
|
|
</pre>
|
|
</div>
|
|
|
|
<p>except during this time, another user had also modified the same line and had done a <code>push</code>.</p>
|
|
|
|
<div style="width: 18em; margin-left: auto; margin-right: auto">
|
|
<pre class="twilight">
|
|
Zoot<span class="StringConstant"><strong>, just Zoot</strong></span>
|
|
</pre>
|
|
</div>
|
|
|
|
<p>Now when you do a:</p>
|
|
|
|
<div>
|
|
|
|
|
|
<pre><code class="zsh">$ git pull
|
|
remote: Counting objects: 5, done.

Auto-merging foo
|
|
CONFLICT (content): Merge conflict in foo
|
|
Automatic merge failed; fix conflicts and then commit the result.
|
|
</code></pre>
|
|
|
|
|
|
</div>
|
|
|
|
<p>Our file <code>foo</code> now contains: </p>
|
|
|
|
<div>
|
|
<pre class="twilight">
|
|
<<<<<<< HEAD:foo
|
|
Zoot <span class="Constant"><strong>the pure</strong></span>
|
|
=======
|
|
<span>Zoot<span class="StringConstant"><strong>, just Zoot</strong></span></span>
|
|
>>>>>>> 2dc7ffb0f186a407a1814d1a62684342cd54e7d6:foo
|
|
</pre>
|
|
</div>
|
|
|
|
<h4 id="conflict-resolution">Conflict resolution</h4>
|
|
|
|
<p>To resolve the conflict you only have to edit the file for example, writing:</p>
|
|
|
|
<div style="width: 18em; margin-left: auto; margin-right: auto">
|
|
<pre class="twilight">
|
|
Zoot <span class="Constant"><strong>the not so pure</strong></span>
|
|
</pre>
|
|
</div>
|
|
|
|
<p>and to commit</p>
|
|
|
|
<div>
|
|
|
|
|
|
<pre><code class="zsh">git commit -a -m "conflict resolved"
|
|
</code></pre>
|
|
|
|
|
|
</div>
|
|
|
|
<p>Now you’re ready to use <a href="http://git-scm.org" title="Git">Git</a>.
|
|
<a href="http://git-scm.org" title="Git">Git</a> provide many other functionnalities. Now we’ll see some <a href="http://git-scm.org" title="Git">Git</a> usages older CVS couldn’t handle.</p>
