My goal for the DSL (created in the web editor) is to generate java code that I can use in other contexts. (for example creating a jar file)

1. How do I invoke the code generation (from the web editor and in general)?
2. How do I specify what I generate?
3. How do I specify where the generated file will be located?

The documentation on this is not very specific or/and not detailed. Either it is too trivial or it is thought of to be clear from the beginning.

As far as I understand it the methods under "Invoking Services" are all regarding the webeditor and its loading, checking and updating.

Am I missing a link to the JS front end frameworks?

(If those frameworks matter I will be using Orion)

no there is no "not understanding" there is simply nothing regarding this. you may digg into https://github.com/eclipse/xtext-web/issues/9 and the forum thread linked there https://www.eclipse.org/forums/index.php?t=msg&th=1076582&goto=1729581&#msg_1729581

Wait what? Very Happy

So what is the purpose of the web editor at the moment without that feature? At some point you want to get working code, right?

And as always, thanks Christian.

Is there a complete example for the requested changes? Could you post a link to it?

I used the code posted by you but it seems I'm missing a part. It seems I don't use the correct resource id?

In my case:
"data-editor-resource-id="example1.create"


with
				jQuery('#generate-button').bind("click", function(e){
					
					jQuery('#generator-result').html('<iframe src="http://' + location.host + '/xtext-service/generate-all?resource=example1.create"></iframe>');
					e.preventDefault();
				});


Firebug responds with:
"NetworkError: 404 The requested resource was not found. - http://localhost:8080/create/xtext-service/load?resource=example1.create"


Steps I did so far:
Created the "CreateXtextServiceDispatcher"
Bound it within "CreateWebModule"
C&P the jQuery part and the html fragments.

And to be honest I'm not that fit with Xtext like Stirling Poon. Very Happy

if there would be i would have pointed you.
and no this is not xtext but javascript crap.

i dont know if you need the service dispatcher at all. this is if you want to deliver multiple artifacts.

you have to make sure the identifier for the model file for the generate is the same as you use for the editor.
and the editor actually needs to have contents !!! otherwise the client will never have talked to the server
since you dont post the complete html and how you actually tested i cannot tell.

i just gave it a try and it works fine.



here is another snippet for just one artifact

https://www.eclipse.org/forums/index.php/t/1073968/?

you can find a all in one here (just made for you)

and if you want to send the full text with the generate request have a look at https://www.eclipse.org/forums/index.php/m/1729826/?srch=xtext+fulltext#msg_1729826
but that example is incomplete as well, but as you can see you can do it.

thus the major problem is: too many possibilities, what to find as common starting usecase

Thanks for your support.
At the moment I can't find the time to browse through the code but at least I can show you the html. I didn't change much yet.

<!DOCTYPE html>
<html>
<head>
	<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
	<meta http-equiv="Content-Language" content="en-us">
	<title>Example Web Editor</title>
	<link rel="stylesheet" type="text/css" href="orion/code_edit/built-codeEdit.css"/>
	<link rel="stylesheet" type="text/css" href="xtext/2.10.0/xtext-orion.css"/>
	<link rel="stylesheet" type="text/css" href="style.css"/>
	<script src="webjars/requirejs/2.2.0/require.min.js"></script>
	<script type="text/javascript">
		var baseUrl = window.location.pathname;
		var fileIndex = baseUrl.indexOf("index.html");
		if (fileIndex > 0)
			baseUrl = baseUrl.slice(0, fileIndex);
		require.config({
			baseUrl: baseUrl,
			paths: {
				"text": "webjars/requirejs-text/2.0.15/text",
				"jquery": "webjars/jquery/2.2.3/jquery.min",
				"xtext/xtext-orion": "xtext/2.10.0/xtext-orion"
			}
		});
		require(["orion/code_edit/built-codeEdit-amd"], function() {
			require(["xtext/xtext-orion"], function(xtext) {
				xtext.createEditor({
					baseUrl: baseUrl,
					syntaxDefinition: "xtext-resources/generated/create-syntax"
				});
				jQuery('#generate-button').bind("click", function(e){
					
					jQuery('#generator-result').html('<iframe src="http://' + location.host + '/xtext-service/generate-all?resource=example1.create"></iframe>');
					e.preventDefault();
				});
			});
		});
	</script>
</head>
<body>

<div class="container">
	<div class="header">
		<h1>Example Create Web Editor</h1>
	</div>
	<div class="content">
		<div 	id="xtext-editor" 
				class="editor" 
				data-editor-xtext-lang="create"
 				data-editor-resource-id="example1.create"
				>
		</div>
 		<div class="button-wrapper">
			<button id="generate-button" value="Generate" title="Generate">Generate</button>
			<div id="generator-result">
				Result
			</div>
		</div>
	</div>
</div>
</body>
</html>


And almost the same css as the shipped example:
body {
	width: 100%;
	height: 100%;
	overflow: hidden;
	font: 16px Helvetica,sans-serif;
}

a {
	color: #22a;
	text-decoration: none;
}

a:hover {
	text-decoration: underline;
}

.container {
	display: block;
	position: absolute;
	top: 0;
	bottom: 0;
	left: 0;
	right: 0;
	margin: 20px;
}

.header {
	display: block;
	position: absolute;
	background-color: #e8e8e8;
	top: 0;
	left: 0;
	right: 0;
	height: 60px;
	padding: 10px;
}

.content {
	display: block;
	position: absolute;
	top: 90px;
	bottom: 0;
	left: 0;
	width: 100%;
	
}

#xtext-editor {
	display: block;
	position: absolute;
	top: 0;
	bottom: 0;
	left: 0;
	right: 0;
	padding: 4px;
	border: 1px solid #aaa;
	width: 640px;
}

.button-wrapper {
	border: 1px solid #aaa;
	display: block;
	left: 750px;
	position: absolute;
	width: 400px;
}


My problem while trying to fix the "not found" problems is that I can't place any text within the editor because it is not reachable. (most likely because of the existing errors). But therefore I can't give the editor code that could be generated.

To track down the issue I first commented the js parts and it still created the errors.
data-editor-resource-id="example1.create"

this is the central issue. As long as this snippet exists within the page, the errors occure. I haven't try to look into what orion tries to do with the tag. Maybe the orion related js already tries to "connect" or execute "something".
But that seems weird to do even before the editor could be manually written.

ps if you dont configure the editor to use a fixed content type and resource id you have to respect that in your stuff as well

require(["orion/code_edit/built-codeEdit-amd"], function() {
			require(["xtext/xtext-orion"], function(xtext) {
				var editor = xtext.createEditor({
					baseUrl: baseUrl,
					syntaxDefinition: "xtext-resources/generated/mydsl-syntax"
				}).done(function(editorViewer) {
					jQuery('#generate-button').bind("click", function(e){
				    var resource = editorViewer.xtextServices.options.resourceId;
					var contentType=editorViewer.xtextServices.contentType;
					jQuery('#generator-result').html('<iframe src="http://' + location.host + '/xtext-service/generate-all?resource='+resource+'&contentType='+contentType+'"></iframe>');
					e.preventDefault();
				});
				});
				
				
				
				
				
			});
		});

well if your orion does not work at all why are we discussing the generate all button?

i dont know here the problem is if it has to do which how you setup orion or if the context of the servlet is not right ..

my code is here https://github.com/cdietrich/xtext-forum-support-example/tree/xtext-orion

Why shouldn't Orion work? It worked so far. Why are you concluding that it isn't working?

The editor highlighting etc works if you remove the "data-editor-resource-id="example1.create"" part. I commited it so that you can see the errors. (that only occure with the generate part)

yes and

var editor = xtext.createEditor({
baseUrl: baseUrl,
syntaxDefinition: "xtext-resources/generated/create-syntax"
}).done(function(editorViewer) {
jQuery('#generate-button').bind("click", function(e){
var resource = editorViewer.xtextServices.options.resourceId;
var contentType=editorViewer.xtextServices.contentType;

var fullText = editorViewer.xtextServices.editorContext.getText();
console.log(fullText);
var data = {
resource : resource,
fullText : fullText,
contextType : contentType
};
jQuery.post('http://localhost:8080/create/xtext-service/generate-all', data, function(result){
jQuery("#generator-result").text(JSON.stringify(result));
});
});
});




works as well (if you had implemented a generator)

Ok. You only created a json output file to be displayed. How do I handle and pack java classes to (for example) a jar?

As far as I understand the Generator within Eclipse hierarchy it creates the java class files within the specified folder. I'm not sure how the ServiceDispatcher "connects" with the customized generator.

Edit:
And within the index.html I get a error:
ReferenceError: editorViewer is not defined

I also updated the repository.

sry as i said 100 posts before: there is nothing like that. you have to implement and care yourself.
are you sure you took the html 1:1 ?

function(editorViewer) {

editor viewer is defined right here

Yes I'm sure.

	<script type="text/javascript">
		var baseUrl = window.location.pathname;
		var fileIndex = baseUrl.indexOf("index.html");
		if (fileIndex > 0)
			baseUrl = baseUrl.slice(0, fileIndex);
		require.config({
			baseUrl: baseUrl,
			paths: {
				"text": "webjars/requirejs-text/2.0.15/text",
				"jquery": "webjars/jquery/2.2.3/jquery.min",
				"xtext/xtext-orion": "xtext/2.10.0/xtext-orion"
			}
		});
		require(["orion/code_edit/built-codeEdit-amd"], function() {
			require(["xtext/xtext-orion"], function(xtext) {
				var editor = xtext.createEditor({
						baseUrl: baseUrl,
						syntaxDefinition: "xtext-resources/generated/create-syntax"
					}).done(function(editViewer) {
						jQuery('#generate-button').bind("click", function(e) {
							var resource = editorViewer.xtextServices.options.resourceId;
							var contentType = editorViewer.xtextServices.contentType;
							var fullText = editorViewer.xtextServices.editorContext.getText();
							console.log(fullText);
							var data = {
										resource: resource,
										fullText: fullText,

										};
							});
						jQuery.post('http://localhost:8080/xtext-service/generate-all', data, function(result) {
							jQuery("#generator-result").text(JSON.stringify(result));
						}); 
					});
			});
		});
	</script>


Take a look at the respository. It is the same there.

(1) editorViewer != editViewer
(2) it is

var data = {
resource : resource,
fullText : fullText,
contextType : contentType
};
jQuery.post('http://localhost:8080/create/xtext-service/generate-all', data, function(result){
jQuery("#generator-result").text(JSON.stringify(result));
});
