<div class="description"><p>Compiles a string with markup into an interpolation function. This service is used by the
HTML <a href="api/ng.$compile"><code>$compile</code></a> service for data binding. See
<a href="api/ng.$interpolateProvider"><code>$interpolateProvider</code></a> for configuring the
interpolation markup.</p>

<pre><code>   <pre class="prettyprint linenums">
         var $interpolate = ...; // injected
         var exp = $interpolate('Hello {{name}}!');
         expect(exp({name:'Angular'}).toEqual('Hello Angular!');

<h3 id="Parameters">Parameters</h3>
<ul class="parameters"><li><code ng:non-bindable="">text – {string} – </code>
<p>The text with markup to interpolate.</p></li>
<li><code ng:non-bindable="">mustHaveExpression<i>(optional)</i> – {boolean=} – </code>
<p>if set to true then the interpolation string must have
embedded expression in order to return an interpolation function. Strings with no
embedded expression will return null for the interpolation function.</p></li>
</ul>
<h3 id="Returns">Returns</h3>
<div class="returns"><code ng:non-bindable="">{function(context)}</code>
– <p>an interpolation function which is used to compute the interpolated
string. The function has these parameters:</p>

<ul>
<li><code>context</code>: an object against which any expressions embedded in the strings are evaluated
against.</li>
</ul></div>
