        <h1 id="usage">Usage</h1>
<p>The <code>hg prompt</code> command takes a single string as an argument and outputs it.
Here's a simple (and useless) example:</p>
<div class="codehilite"><pre><span class="gp">$</span> hg prompt <span class="s2">&quot;test&quot;</span>
<span class="go">test</span>
</pre></div>


<p>Keywords in curly braces can be used to output repository information:</p>
<div class="codehilite"><pre><span class="gp">$</span> hg prompt <span class="s2">&quot;currently on {branch}&quot;</span>
<span class="go">currently on default</span>
</pre></div>


<p>Keywords also have an extended form:</p>
<div class="codehilite"><pre>{optional text{branch}more optional text}
</pre></div>


<p>This form will output the text and the expanded keyword <strong>only</strong> if the
keyword successfully expands. This can be useful for displaying extra text
only if it's applicable:</p>
<div class="codehilite"><pre><span class="gp">$</span> hg prompt <span class="s2">&quot;currently on {branch} and at {bookmark}&quot;</span>
<span class="go">currently on branch default and at</span>

<span class="gp">$</span> hg prompt <span class="s2">&quot;currently on {branch} {and at {bookmark}}&quot;</span>
<span class="go">currently on branch default</span>

<span class="gp">$</span> hg bookmark my-book

<span class="gp">$</span> hg prompt <span class="s2">&quot;currently on {branch} {and at {bookmark}}&quot;</span>
<span class="go">currently on branch default and at my-book</span>
</pre></div>


<p>You can give the <code>--angle-brackets</code> option to use angle brackets for keywords
instead of curly brackets. This can come in handy when combining a simple
prompt string with more complicated shell functionality (like color
variables):</p>
<div class="codehilite"><pre><span class="gp">$</span> hg prompt <span class="s2">&quot;{currently on {branch}}&quot;</span>
<span class="go">currently on default</span>

<span class="gp">$</span> hg prompt --angle-brackets <span class="s2">&quot;&lt;currently on &lt;branch&gt;&gt;&quot;</span>
<span class="go">currently on default</span>
</pre></div>


<p>Take a look at the <a href="../keywords/">keywords</a> documentation to see all the keywords
<code>hg-prompt</code> supports.</p>
