-In this step, we have determined that the built-in angular display filters ({@link
-angular.filter.number number}, {@link angular.filter.currency currency}, {@link
-angular.filter.date date}, etc.) don't handle what we want to do, so we get to create our own
-custom {@link angular.filter filter}.
-
-In the previous step, the details page displayed either "true" or "false" to indicate whether
-certain phone features were present or not. Our custom "checkmark" filter replaces those text
-strings with glyphs: ✓ for "true", and ✘ for "false".
-
-Our filter code lives in `app/js/filters.js`:
-
-__`app/index.html`:__
-<pre>
-...
- <script src="lib/angular/angular.js" ng:autobind></script>
- <script src="js/controllers.js"></script>
- <script src="app/js/filters.js"></script>
-...
-</pre>
-
-In the phone details template, we employ our filter for angular expressions whose values are
-"true" or "false"; `{{ [phone_feature] | checkmark }}`:
-
-__`app/partials/phone-detail.html`:__
-<pre>
-<img ng:src="{{phone.images[0].large}}" class="phone"/>
-<h1>{{phone.name}}</h1>
-<p>{{phone.description}}</p>
-...
-<ul class="specs">
- ...

- <span>Connectivity</span>

- <dd>{{phone.connectivity.cell}}</dd>

- <dd>{{phone.connectivity.wifi}}</dd>

- <dt>Infrared</dt>
- <dd>{{phone.connectivity.infrared | checkmark}}</dd>
- <dt>GPS</dt>
- <dd>{{phone.connectivity.gps | checkmark}}</dd>
- </dl>
- </li>
-...
-</ul>
-</pre>
-
-__`app/js/filters.js`:__ (New)
-<pre>
-angular.filter('checkmark', function(input) {
- return input ? '\u2713' : '\u2718';
-});
-</pre>
-
-__`test/unit/filtersSpec.js`:__ (New)

- it('should convert boolean values to unicode checkmark or cross', function() {

- expect(angular.filter.checkmark(false)).toBe('\u2718');
- });
-})
-</pre>
-
-## Discussion:
-
-* This example shows how easy it is to roll your own filters for displaying data. As explained in
-the "Writing your own Filters" section of the {@link angular.filter angular.filter} page, you
-simply register your custom filter function on to the `angular.filter` function.
-
-* In this example, our filter name is "checkmark"; our input is either "true" or "false", and we
-return one of two unicode characters we have chosen to represent true or false (`\u2713` and
-`\u2718`).
-
-* We created a new unit test to verify that our custom filter converts boolean values to unicode
-characters.

+In this step you will learn how to create your own custom display filter.
+
+1. Reset your workspace to Step 9 using:
+
+ git checkout --force step-9
+
+or
+
+ ./goto_step.sh 9
+
+2. Refresh your browser or check the app out on {@link
+http://angular.github.com/angular-phonecat/step-9/app our server}. Navigate to one of the detail
+pages.
+
+In the previous step, the details page displayed either "true" or "false" to indicate whether
+certain phone features were present or not. We have used a custom filter to convert those text
+strings into glyphs: ✓ for "true", and ✘ for "false". Let's see, what the filter code looks like.
+
+The most important changes are listed below. You can see the full diff on {@link
+https://github.com/angular/angular-phonecat/compare/step-8...step-9
+GitHub}:
+
+
+## Custom Filter
+
+In order to create a new filter, simply register your custom filter function with the `{@link
+angular.filter angular.filter}` API.
+
+__`app/js/filters.js`:__
+<pre>
+angular.filter('checkmark', function(input) {
+ return input ? '\u2713' : '\u2718';
+});
+</pre>
+
+The name of our filter is "checkmark". The `input` evaluates to either "true" or "false", and we
+return one of two unicode characters we have chosen to represent true or false (`\u2713` and
+`\u2718`).
+
+
+## Template
+
+Since the filter code lives in the `app/js/filters.js` file, we need to include this file in our
+layout template.
+
+__`app/index.html`:__
+<pre>
+...
+ <script src="js/controllers.js"></script>
+ <script src="js/filters.js"></script>
+...
+</pre>
+
+The syntax for using filters in angular templates is as follows:
+
+ {{ expression | filter }}
+
+Let's employ the filter in the phone details template:
+
+
+
+__`app/partials/phone-detail.html`:__
+<pre>
+...
+ <dl>
+ <dt>Infrared</dt>
+ <dd>{{phone.connectivity.infrared | checkmark}}</dd>
+ <dt>GPS</dt>
+ <dd>{{phone.connectivity.gps | checkmark}}</dd>
+ </dl>
+...
+</pre>
+
+
+## Test
+
+Filters, like any other component, should be tested and these tests are very easy to write.
+
+__`test/unit/filtersSpec.js`:__
+<pre>
+describe('checkmark filter', function() {
+
+ it('should convert boolean values to unicode checkmark or cross', function() {
+ expect(angular.filter.checkmark(true)).toBe('\u2713');
+ expect(angular.filter.checkmark(false)).toBe('\u2718');
+ });
+})
+</pre>
+
+To run the unit tests, execute the `./scripts/test.sh` script and you should see the following
+output.
+
+ Chrome: Runner reset.
+ ....
+ Total 4 tests (Passed: 4; Fails: 0; Errors: 0) (3.00 ms)
+ Chrome 11.0.696.57 Mac OS: Run 4 tests (Passed: 4; Fails: 0; Errors 0) (3.00 ms)
+
+
+Now that you have learned how to write and test a custom filter, go to Step 10 to learn how we can
+use angular to enhance the phone details page further.
