Autocompletion for mid-keywords

[JoanGi]

Hi,

I've realized that autocompletion is not returning suggestion when you are at the mid-keyword, and this is not followed attribute like ID.

I will try to explain myself. Given this grammar:

grammar MyDSL

entry MyDSL:
   (elements+=Declaration);

Declaration:
'Title:' title=ID
'Version:' version=NUMBER;

// Terminals
hidden terminal WS: /\s+/;
terminal ID: /[_a-zA-Z][\w_]*/;
terminal STRING: /"(\\.|[^"\\])*"|'(\\.|[^'\\])*'/;
terminal NUMBER returns number: /[0-9]+(\.[0-9]*)?/;  

The completion in the mid-keyword of version do not work (see image above in the playground).

But if we change version for version=ID. It works:

To enable autocompletion during mid-keyword, a leaf of the AST is created with the temporal text written, but this does not happen with other types of terminals. I've thought it was a scope problem, but the autocompletion works just before to start typing the keyword.

In my use-case this will improve the UX. Any thought about why this is happening? Thank you very much!!!

I've created an issue for this at #930, it's the same root cause as #778.

Nevermind, I've seen that the fix for #778 has not been released yet. When linking Langium locally it works as expected. We will release 1.1.0 this week:
