UI.Ace directive

This directive allows you to add ACE editor elements.

Requirements

AngularJS
Ace 1.x

Usage

You can get it from Bower

bower install angular-ui-ace\#bower

This will copy the UI.Ace files into a bower_components folder, along with its dependencies. Load the script files in your application:

<script type="text/javascript" src="bower_components/ace-builds/src-min-noconflict/ace.js"></script>
<script type="text/javascript" src="bower_components/angular/angular.js"></script>
<script type="text/javascript" src="bower_components/angular-ui-ace/ui-ace.js"></script>

Add the UI.Ace module as a dependency to your application module:

var myAppModule = angular.module('MyApp', ['ui.ace']);

Finally, add the directive to your html:

<div ui-ace></div>

To see something it's better to add some CSS, like

.ace_editor { height: 200px; }

Options

Ace doesn't provide a one gate access to all the options the jquery way. Each option is configured with the function of a specific instance. See the api doc for more.

Although, ui-ace automatically handles some handy options :

showGutter : to show the gutter or not.
useWrapMode : to set whether or not line wrapping is enabled.
theme : to set the theme to use.
mode : to set the mode to use.
onLoad : callback when the editor has finished loading (see below).
onChange : callback when the editor content is changed ().

<div ui-ace="{
  useWrapMode : true,
  showGutter: false,
  theme:'twilight',
  mode: 'xml',
  onLoad: aceLoaded,
  onChange: aceChanged
}"></div>

You'll want to define the onLoad and the onChange callback on your scope:

myAppModule.controller('MyController', [ '$scope', function($scope) {

  $scope.aceLoaded = function(_editor) {
    // Options
    _editor.setReadOnly(true);
  };

  $scope.aceChanged = function(e) {
    //
  };

}]);

To handle other options you'll have to use a direct access to the Ace created instance (see below).

Working with ng-model

The ui-ace directive plays nicely with ng-model.

The ng-model will be watched for to set the Ace EditSession value (by setValue).

The ui-ace directive stores and expects the model value to be a standard javascript String.

Can be read only

Simple demo

<div ui-ace readonly="true"></div>
or
Check me to make Ace readonly: <input type="checkbox" ng-model="checked" ><br/>
<div ui-ace readonly="{{checked}}"></div>

Ace instance direct access

For more interaction with the Ace instance in the directive, we provide a direct access to it. Using

<div ui-ace="{ onLoad : aceLoaded }" ></div>

the $scope.aceLoaded function will be called with the Ace Editor instance as first argument

myAppModule.controller('MyController', [ '$scope', function($scope) {

  $scope.aceLoaded = function(_editor){
    // Editor part
    var _session = _editor.getSession();
    var _renderer = _editor.renderer;

    // Options
    _editor.setReadOnly(true);
    _session.setUndoManager(new ace.UndoManager());
    _renderer.setShowGutter(false);

    // Events
    _editor.on("changeSession", function(){ ... });
    _session.on("change", function(){ ... });
  };

}]);

Testing

We use Karma and jshint to ensure the quality of the code. The easiest way to run these checks is to use grunt:

npm install -g grunt-cli
npm install && bower install
grunt

The karma task will try to open Firefox and Chrome as browser in which to run the tests. Make sure this is available or change the configuration in test\karma.conf.js

Grunt Serve

We have one task to serve them all !

grunt serve

It's equal to run separately:

grunt connect:server : giving you a development server at http://127.0.0.1:8000/.
grunt karma:server : giving you a Karma server to run tests (at http://localhost:9876/ by default). You can force a test on this server with grunt karma:unit:run.
grunt watch : will automatically test your code and build your demo. You can demo generation with grunt build:gh-pages.
