Xtext Web Editor [message #1734627]

Fri, 10 June 2016 02:34

Good morning all,

I'm currently working on a dsl for educational institutions. This DSL should provide features like describing course syllabi, program descriptions etc. Since the dsl should also be used by people who are not from the PC domain, i wanted to use the web editor.

However I did not manage to install one of the three Orion, Ace or CodeMirror after several hours of research and checks. Does there exist a tutorial for running one of these 3? Or could I get any help please?

Additionally I wanted to ask if the web editors provide the feature to create some sort of project explorer to create multiple files of my DSL? I've seen that dsl forge provides some sort of project explorer but I think it covers less functionalities than the Xtext web editors?

Thank you for any information and help
Benjamin

Thank you for your fast reply, well actually I've added in the MWE2Workflow in the language section the webSupport section : Here the code

language = StandardLanguage {
			name = "lu.uni.lassy.messep.tesma.Tesma"
			fileExtensions = "tes"

			serializer = {
				generateStub = false
			}
			
			[i]webSupport = {
				generateHtmlExample = true
				framework = "CODEMIRROR"
			}[/i]

			validator = {
				// composedCheck = "org.eclipse.xtext.validation.NamesAreUniqueValidator"
			}

and I've changed the script section in the index.html file to

require.config({
		    paths: {
		        "jquery": "webjars/jquery/<version>/jquery.min",
		        "xtext/xtext-codemirror": "xtext/<version>/xtext-codemirror"
		    },
		    packages: [{
		        name: "codemirror",
		        location: "webjars/codemirror/<version>",
		        main: "lib/codemirror"
		    }]
		});
		require(["xtext/xtext-codemirror"], function(xtext) {
		    xtext.createEditor();
		});
		}

and then I've executed the jettyrun command, the server starts properly but the textbox is actually not editable in the web application, neither in chrome or safari.

In attachement, I've put a screenshot of the web browser.

Thank you in advance

first question: did you give it a try with ace first (default setup)?
was it working?

did you adapt build.gradle for the codemirror web jar to be downloaded.

when you open the browser and have a look at the javascript console - which errors do you get ?

do you get any errors in the console of the jettyrun?

and you may need to add a

def void configureIPreferenceValuesProvider(Binder binder) {
binder.bind(IPreferenceValuesProvider).annotatedWith(FormatterPreferences).to(FormatterPreferenceValuesProvider)
}

to the webmodule if you use xtext 2.10

i filed https://bugs.eclipse.org/bugs/show_bug.cgi?id=495851

for that

Great Thank you for your help.. I made it actually run with the ACE standard version run after reinstalling a new Eclipse Java and updating with the Xtext update site. It was actually due to the low internet connection I had. It could not download a file (i do not remember the name) for making jettyrun run.

This is a very important piece of information. I have wasted 1 day figuring out my mistake. I recently downloaded Xtext 2.10 for using Xtext on Web. And i ran into this error which I could not find any help for. Now it's working fine.

Thanks for writing the solution.

Hi Christian

I want to understand how the Xtext on the web works, the various artifacts that gets generated in the .web project, use of the three javascript editor libraries, how could I save files from the browser (like we did in the eclipse version). Do you have an architecture for the "web support" feature so that it is easier to understand the new concepts.

Thanks in advance,
Puneet

The Xtext Web integration is not an IDE. If you want to save any files, you need to take care of that yourself by extending the server implementation. See the documentation.

Hi

Do I need to bind the IServerResourceHandler in WebModule code? Can you help me with a link that shows how I can implement the persistence mechanism? I am lost. I am also unable to run Orion editor. I can use the default ACE editor easily. I have seen the documentation on the official website but I do not think its sufficient to get a complete idea as to what is happening behind the curtains. I am very curious to know how the things are working within Xtext.

Thanks

Yes you can use the web module.
I don't know any public example besides this one
https://github.com/eclipse/xtext-web/blob/master/org.eclipse.xtext.web/src/main/xtend-gen/org/eclipse/xtext/web/server/persistence/FileResourceHandler.java
For Orion: did you download and extract the Orion javascript files?
