Hi,
I am using the Xtext (Web version) for creating a Web Editor for my language.
When i run my language as an Eclipse plugin, the content assist is ok, however, when i run my Web Editor (not with the use of Eclipse - in the localhost) the custom content assist is not working.
My costumizations concern the class
class EdlProposalProvider extends AbstractEdlProposalProvider (Edl is the name of my language)
that are not presented in the Web version of the editor by pressing Ctrl-Space.
Am i processing the correct file for the content assist of the Web editor?

BR

for web you have to customize org.eclipse.xtext.ide.editor.contentassist.IdeContentProposalProvider

make sure you dont stumble over https://github.com/eclipse/xtext-web/issues/5

There is one for xbase: https://github.com/eclipse/xtext-extras/blob/master/org.eclipse.xtext.xbase.ide/src/org/eclipse/xtext/xbase/ide/contentassist/XbaseIdeContentProposalProvider.xtend
The concept is the same as in the generated Eclipse-based proposal provider but you have to do the case-switching based on your grammar.

I am facing a similar issue. I customized the list of proposals for some grammar elements by overriding corresponding methods in MyDSLProposalProvoder.xtend. This works fine within eclipse plugin.

But I can't get the same functionality to work in the browser. The web server runs without errors. The browser based editor shows proposals that can be derived from the grammar but unlike the plugin editor the browser version doesn't show the customized proposals.

I am a bit new to xtext and I can't quite follow the proposed solution. Is there a bit more step by step guide / code snippets for get this to work?

You need to subclass and bind the idecontentproposalprovider in the ide module
Which of this two parts you don't understand

With the two statemachine links you have provided, it is much easier for me to understand what I need to do than with the xbase link you provided earlier in the discussion.

Now, I am able to produce my custom proposals in the web based version as well.

Thanks much.
