Code Edit Widget With Language Tooling

To make it easier to consume the Orion editor with the complete language tooling, a new widget called "Code Edit" has been introduced. The widget consists of the core editor and all Web development language tools, including the Tern analysis engine and Esprima parser. The widget is delivered as a zip file containing all the structural folders and files, making the core and the plugins all work together. You can easily embed this widget directly into any client side Web application. The language tooling plugins are only loaded when needed, making it easier to embed a powerful code editor without hurting page load time. The widget core is available both unminified, for debugging purpose and minified, for better loading time. The plugins are only available in minified version.

Getting the build

  • Users can grab the most recent "Code Edit" widget from the nightly builds or they can use the latest release available on the Orion download page.
  • From the Orion build page, users can click on a nightly build or a release and they will be presented with a page that now includes the code edit widget: the built-codeEdit.zip file contains all the files for you to embed the widget.

Using the build and the quick start demo

You can simply download the zip file and unzip it into a folder on your web server. Below is a complete run-able html file that you can host in your web server as a demo on how to consume the widget. Assume that you have created a folder named editorBuild under where your html file lives. Follow the 3 steps below and you can run the demo in just a few minutes. The same demo is also running here, where you can see it right away.

  • Download the code edit build and unzip it under the editorBuild folder.
  • Create a demo.html and paste the example contents into the demo.html.
  • Run the demo.html.

Your demo page should look like this, if you use CTRL+space as content assist after the page is loaded.

Consuming the widget in different ways

Closer look at the build

If you unzip the build, the file structure looks like below:

WidgetCore.png

There are several folders in the build, you should copy them all to your web server but only reference the files under the code_edit folder. All other files from other folders will be loaded dynamically as plugins depending on the file MIME type. The built-codeEdit.css file provides all the default css classes used in the widget. The built-codeEdit.min.js file provides the widget core code in a compact size while the built-codeEdit.js file provides the readable code for debugging purpose. Both of the .js files can be consumed by either loading the widget directly or using the RequireJS module loader.

Loading the widget directly

Assuming that you've unzipped the build into a folder called editorBuild, the following code in an html file shows you how to load the widget.

<link rel="stylesheet" type="text/css" href="editorBuild/code_edit/built-codeEdit.css"/>
<script src="editorBuild/code_edit/built-codeEdit.min.js"></script>
<script>
    window.onload=function(){
        var codeEdit = new orion.codeEdit();
        //Use codeEdit from here
    };
</script>

Note that orion.codeEdit is the only global function that the built-codeEdit.min.js exports after it is loaded. You need to call the create API to create an editor with your text contents. Details is addressed in a later section.

using the RequireJS module loader

Warning2.png
The information on this section applies only to the code edit widget build after the 10.0 stream stable build S20150629-1217

Assuming that you've unzipped the build into a folder called editorBuild and you want to use the RequireJS module loader, the following code in an html file shows you how to load the widget. Note that the AMD build exposes a module called orion/codeEdit as the widget root. You can also load other Orion modules that are built into the widget, such as orion/Deferred, etc.

<link rel="stylesheet" type="text/css" href="editorBuild/code_edit/built-codeEdit.css"/>
<script>
require.config({
    bundles: {
        "editorBuild/code_edit/built-codeEdit-amd": ["orion/codeEdit", "orion/Deferred"]
    }	    
});
require(["orion/codeEdit", "orion/Deferred"], function(mCodeEdit, Deferred) {
	var codeEdit = new mCodeEdit();
	var contents = 'var foo = "bar";'; 
	codeEdit.create({parent: "embeddedEditor"/*editor parent node id*/}).then(function(editorViewer) {
		editorViewer.setContents(contents, "application/javascript");
	});
});
</script>

Other than using require.config as above, you can also use another flavor of loading as below:

<link rel="stylesheet" type="text/css" href="editorBuild/code_edit/built-codeEdit.css"/>
<script>
require(["editorBuild/code_edit/built-codeEdit-amd"], function() {
    require(["orion/codeEdit", "orion/Deferred"], function(mCodeEdit, Deferred) {
	var codeEdit = new mCodeEdit();
	var contents = 'var foo = "bar";'; 
	codeEdit.create({parent: "embeddedEditor"/*editor parent node id*/}).then(function(editorViewer) {
		editorViewer.setContents(contents, "application/javascript");
	});
    });
});
</script>

Note that the way how the widget is loaded is slightly different but either way you end up with a widget instance called codeEdit. Lets talk about how to use the codeEdit instance in the next section.

using the codeEdit.create function

As described in the previous section, now you are holding an instance of the code edit widget called codeEdit. Every time you call codeEdit.create function, it creates an Orion editor instance and shows your editor text right away. There are two ways to call the codeEdit.create function.

A simple way to call codeEdit.create

If you want to create your editor and leave it there by using all the default settings, refer to the following code.

codeEdit.create({parent: "myEditorDivId", contentType: "application/javascript", contents: "var foo;"});

An advanced way to call codeEdit.create

If you want to create your editor and reuse the editor instance for customization and even for different contents by the same editor instance, refer to the following code.

codeEdit.create({parent: "myEditorDivId"}).then(function(editorViewer) {
    editorViewer.setContents("var foo;", "application/javascript");
    //editorViewer.editor.textView.setText("var bar;");
});

Setting your editor to readonly after the creation

Although there are other ways to create a readonly editor but the simplest way is to set the editorViewer.readonly property to true.

codeEdit.create({parent: "myEditorDivId"}).then(function(editorViewer) {
    editorViewer.setContents("var foo;", "application/javascript");
    editorViewer.readonly = true;
});

Parameters used in the codeEdit.create call

The codeEdit.create function call returns a javascript promise object that you can reuse. Note that either you use the simple or advanced way to create your editor, there are 3 parameters required. When you use the simple way, you just pass an object with {parent, contentType, contents} and you do not care the promise. When you use the advanced way, you only pass {parent} but when you handle the promise object, which is the editorViewer object, you will pass the contents and content type to the editorViewer.setContents. Note that is you hold editorViewer.setContents instance somewhere in your code, you can just reuse the same instance for different contents. This is useful when you want to keep an editor open but keep changing the contents for the time being.

parent parameter

This can be either a DIV id or DIV node that holds your editor.

contents parameter

This is a string parameter that you use to initialize your editor contents. The contents can be modified after the editor is up.

contentType parameter

The code edit widget uses MIME types for syntax highlighting and language tooling. The parameter is a string that present a MIME type, such as "application/javascript". By default, the widget supports the syntax highlighting for the following MIME types.

  • "application/javascript"
  • "application/x-ejs"
  • "text/css"
  • "text/html"
  • "text/x-java-source"
  • "application/x-jsp"
  • "application/json"
  • "text/x-launch"
  • "text/x-jade"
  • "text/x-python"
  • "text/x-ruby"
  • "text/x-go"
  • "text/x-objective-c"
  • "text/x-php"
  • "text/x-swift"
  • "application/xml"
  • "application/xhtml+xml"
  • "text/x-yaml"
  • "text/x-arduino"
  • "text/x-csrc"
  • "text/x-c"
  • "text/x-csharp"
  • "text/x-cshtml"
  • "text/x-c++src"
  • "text/x-dockerfile"
  • "text/x-erlang"
  • "text/x-haml"
  • "text/x-lua"
  • "application/xquery"
  • "text/x-vb"
  • "text/x-vbhtml"

Theming your editor

As described in the previous sections, if you use the advanced way to create your editor you will get hold of an editorViewer instance. The fundamental class of an Orion editor is called TextView that is theme-able in different ways. If you call editorViewer.editor.getTextView() it returns you an instance of TextView. You can then call editorViewer.editor.getTextView().setOptions({themeClass: "editorTheme"}) to theme your editor. Note that "editorTheme" is the class selector that is defined in the following css, as the default theme that the widget is using. You can change any of the classes for your own theme.

}

You can copy the above contents and paste into your own css file and load the css file into your page. Then change your code to call editorViewer.editor.getTextView().setOptions({themeClass: "editorTheme"}) , after editorViewer.setContents is called. Refer to the snippet below, assuming that you've created the css file called editorTheme.css and loaded into your page.

codeEdit.create({parent: "myEditorDivId"}).then(function(editorViewer) {
    editorViewer.setContents("var foo;", "application/javascript");
    editorViewer.editor.getTextView().setOptions({themeClass: "editorTheme"});
});

Theming the syntax highlighting

Refer to TextMate Language Grammars at section 12.4 Naming Conventions on how to change the css class values in the editorTheme.css file. For instance if you change one of the classes as below, your syntax highlighting on the javascript control keyword will become green from dark orange(default).

.editorTheme .keyword.control {
	color: green;/*#CC4C07;*/
	font-weight: bold;
}

Other options to customize your editor

Passing user plugins

You can pass a list of your own plugins by passing the userPlugins option when you call codeEdit.create API. Refer to here on how to write your own plugins.

codeEdit.create({parent: "myEditorDivId", userPlugins: ["your plugin URL1", "your plugin URL2"]}).then(function(editorViewer) {
    editorViewer.setContents("var foo;", "application/javascript");
    editorViewer.editor.getTextView().setOptions({themeClass: "editorTheme"});
});

The editorViewer promise

As mentioned in the previous section, when you call codeEdit.create API a promise object editorViewer is returned. There are 3 major instances wrapped by the editorViewer, by which you can use to customize your editor further.

  • editorViewer.serviceRegistry
  • editorViewer.editor
  • editorViewer.inputManager

The editorViewer.serviceRegistry instance

The editorViewer.serviceRegistry is an instance of Orion serviceRegistry by which you can register your own services to extend your editor. Below is a sample snippet on how to register a simple(fake) content assist service on an xml file.

var contentAssistProvider = {
    computeProposals: function(buffer, offset, context) {
        var result = [];
        for(var i = 0; i < 10; i++){
            result.push("proposal " + i);
        }
        return result;
    }
};
editorViewer.serviceRegistry.registerService("orion.edit.contentassist",
    contentAssistProvider,
    { name: "xmlContentAssist",
      contentType: ["application/xml"]
    });

The editorViewer.editor instance

The editorViewer.editor is an instance of Orion editor by which you can use to customize your editor in details. Below is a sample snippet on how to call the editor's APIs to set your editor's theme and disable some editor rulers.

editorView.editor.getTextView().setOptions({themeClass: "editorTheme"});
editorView.editor.setLineNumberRulerVisible(false);
editorView.editor.setAnnotationRulerVisible(false);
editorView.editor.setOverviewRulerVisible(false);
editorView.editor.setFoldingRulerVisible(false);

The editorViewer.inputManager instance

The editorViewer.inputManager is an instance of editor input manager by which you can use to customize the input for an editor. The most important API you may want to use is the setAutoSaveTimeout. By default the editorViewer.inputManager sets the autoSaveTimeOut as 300ms to trigger code validation. If you do not want to trigger code validation automatically use the code as below to turn it off.

editorViewer.inputManager.setAutoSaveTimeout(-1);

Frequent asked questions

How to provide a markdown type of hover service

Assume that you want to provide a hover service as shown below.

FAQ hoverExample.png

There you want your hover service title as bold and the contents of the hover information as paragraphs with bold, italic, etc. By default the hover title is styled as normal font but you can change it by overriding the css as below:

.textviewTooltip .hoverTooltipTitle {
    font-weight: bold;
}

For the different fonts and paragraphs of the contents, you can use the markdown specification. The snippet below shows how to achieve this as an example.

var hoverProvider = {
    computeHoverInfo: function (editorContext, context) {
        var pContent = "_This text will be italic_  \n\n__This text will be bold__  \nThis text is normal";
        return { title: "This is the title",
		 content: pContent,
		 type: "markdown"};
};
editorViewer.serviceRegistry.registerService("orion.edit.hover",
    hoverProvider,
    { name: "xmlContentHover",
      contentType: ["application/xml"]
    });

How to turn on/off the readonly flag on the same editorViewer.editor instance

The readonly flag can be set after the editor creation but assume that you hold an editorViewer instance for the time being and want to turn on/off the readonly flag depending on what type of contents are reloaded into the same editorViewer.editor instance. You can use the two lines of API calls as show below:

editorViewer.readonly = true;
editorViewer.editor.getTextView().setOptions({"readonly": true});

How to highlight a line in the editor and set cursor on that line

Assume that you want to highlight a line in your editor with your own line and gutter style as below.

FAQ highlightLine.png

For example, when your editor is up you want to double click on the gutter of a certain line and highlight the gutter with red background color and dotted outline for the line of text. If you double click on an existing gutter, the gutter and the line highlight go away. Below is a completely run-able HTML file that shows you how to achieve this.
