        <h1 id="sample-prompts">Sample Prompts</h1>
<p><code>hg-prompt</code> supports many keywords, but you probably don't want to use them
all at once. Which keywords you'll find useful depends on the workflow(s) you
commonly use.</p>
<p>Here are some example prompts to get you started.</p>
<h2 id="a-basic-prompt">A Basic Prompt</h2>
<p>A very simple prompt could tell you:</p>
<ul>
<li>Which named branch you're currently working on.</li>
<li>If there are any uncommitted changes in the working directory.</li>
<li>If you're at a revision that's not a branch tip (i.e. if running <code>hg update</code>
  would do something).</li>
</ul>
<p>To get a prompt like this you could add this to your <code>~/.bashrc</code> file:</p>
<div class="codehilite"><pre><span class="nb">export </span><span class="nv">PS1</span><span class="o">=</span><span class="s1">&#39;\u in \w`hg prompt &quot;{on {branch}}{status}{update}&quot; 2&gt;/dev/null` $&#39;</span>
</pre></div>


<p>The result would look something like this:</p>
<div class="codehilite"><pre>username in ~/src $ cd project
username in ~/src/project on feature-branch $ touch sample
username in ~/src/project on feature-branch? $ hg add sample
username in ~/src/project on feature-branch! $ hg commit -m &#39;Add a file.&#39;
username in ~/src/project on feature-branch $ hg update default
username in ~/src/project on default $ hg update 0
username in ~/src/project on default^ $
</pre></div>


<p>The <code>2&gt;/dev/null</code> part of the prompt command prevents errors from showing when
you're not currently in a Mercurial repository.</p>
<p>The keywords (<code>{branch}</code>, <code>{status}</code> and <code>{update}</code>) display the relevant
information.</p>
<p>The extra text in the <code>{branch}</code> keyword will only display if a branch exists,
so you won't see the word "on" if you're not in a repository.</p>
<h2 id="a-more-compact-basic-prompt">A More Compact Basic Prompt</h2>
<p>Some people prefer a smaller, less obtrusive prompt. To get that kind of
prompt you can omit some of the less important text:</p>
<div class="codehilite"><pre><span class="nb">export </span><span class="nv">PS1</span><span class="o">=</span><span class="s1">&#39;\w`hg prompt &quot;[{branch}{status}{update}]&quot; 2&gt;/dev/null` $&#39;</span>
</pre></div>


<p>That will give you something like this:</p>
<div class="codehilite"><pre>~/src $ cd project
~/src/project[feature-branch] $ touch sample
~/src/project[feature-branch?] $ hg add sample
~/src/project[feature-branch!] $ hg commit -m &#39;Add a file.&#39;
~/src/project[feature-branch] $ hg update default
~/src/project[default] $ hg update 0
~/src/project[default^] $
</pre></div>
