For more detailed information refer to this document: https://docs.google.com/a/google.com/document/d/1pbtW2yvtmFBikfRrJd8VAsabiFkKezmYZ_PbgdjQOVU/edit **Example:** ```html {{recipients.length, plural, offset:1 =0 {You gave no gifts} =1 { {{ recipients[0].gender, select, male {You gave him a gift.} female {You gave her a gift.} other {You gave them a gift.} }} } one { {{ recipients[0].gender, select, male {You gave him and one other person a gift.} female {You gave her and one other person a gift.} other {You gave them and one other person a gift.} }} } other {You gave {{recipients[0].gender}} and # other people gifts. } }} ``` This is a SEPARATE module so you MUST include `angular-messageformat.js` or `angular-messageformat.min.js`. In addition, your application module should depend on the "ngMessageFormat" (e.g. angular.module('myApp', ['ngMessageFormat']);) When you use the `ngMessageFormat`, the $interpolate gets overridden with a new service that adds the new MessageFormat behavior. **Syntax differences from MessageFormat:** - MessageFormat directives are always inside `{{ }}` instead of single `{ }`. This ensures a consistent interpolation syntax (else you could interpolate in more than one way and have to pick one based on the features availability for that syntax.) - The first part of such a syntax can be an arbitrary Angular expression instead of a single identifier. - You can nest them as deep as you want. As mentioned earlier, you would use `{{ }}` to start the nested interpolation that may optionally include select/plural extensions. - Only `select` and `plural` keywords are currently recognized. - Quoting support is coming in a future commit. - Positional arguments/placeholders are not supported. They don't make sense in Angular templates anyway (they are only helpful when using API calls from a programming language.) - Redefining of the startSymbol (`{{`) and endSymbol (`}}`) used for interpolation is not yet supported.

You must specify the MessageFormat function that you're using right after the
|
|
comma following the Angular expression. Currently, the supported functions are
|
|
"plural" and "select" (for gender selections.)
