I am using intellij and exploring web editor.
I would like to show the auto-complete proposal list without having to press Ctrl+Space . Like configure it for spacebar or blank space .

Please suggest Smile

Hi,

your questions are kind a missleading. you are targeting web. it does not matter if you develop in eclipse or intellij.
since the content assist is called by the client i guess you have to hack this somehow yourself.
the how depends on the client side editor impl.

from the code i can see there is no default hook for xtext-ace.
feel free to file an enhancement request.

Ok.The reason for me mentioning about eclipse and intellij was because I thought it would be different based on the generated classes.

It is
There is a class for eclipse one for idea and one for the web
You can enableLiveAutocompletion in ace but that will not react on space but on alphanumeric only

var editor = xtext.createEditor(...).setOptions({enableLiveAutocompletion:true}); // adaption of js code in index html

digging into the ace api gives you following adaption to get live autocomplete all the time (including spaces through adapting the default regex)

var editor = xtext.createEditor({
					
					baseUrl: baseUrl,
					syntaxDefinition: "xtext-resources/generated/mode-mydsl2"
				});
				editor.completers.forEach(function(completer, i) {completer.identifierRegexps = [/[ a-zA-Z_0-9\$\-\u00A2-\uFFFF]/];});
				editor.setOptions({enableLiveAutocompletion: true})

For the Orion editor you can configure arbitrary characters to trigger content assist. For example, in order to do this for the space bar, include the option

contentAssistCharTriggers: " "

in your xtext.createEditor(..) call (in JavaScript).

See the charTriggers parameter in the Orion documentation:
https://wiki.eclipse.org/Orion/Documentation/Developer_Guide/Plugging_into_the_editor#orion.edit.contentAssist

Hi Christian ,

I have added the below to index.html file as

//snippet.
require(["webjars/ace/1.2.0/src/ace"], function() {
require(["xtext/xtext-ace"], function(xtext) {
xtext.createEditor({
baseUrl: baseUrl,
syntaxDefinition: "xtext-resources/generated/mode-eindsl",
}).completers.forEach(function(completer, i) {completer.identifierRegexps = [/[ a-zA-Z_0-9\$\-\u00A2-\uFFFF]/];}).setOptions({enableLiveAutocompletion: true});

I am not good with javascript. Please advise if this is the right way.
