Template global example:

package org.acme;

import io.quarkus.qute.TemplateGlobal;

enum Color { RED, GREEN, BLUE }

@TemplateGlobal
public class Globals {

    static int age = 40;

    static String name;

    static Color[] myColors() {
      return new Color[] { Color.RED, Color.BLUE };
    }

    @TemplateGlobal(name = "currentUser")
    static String user() {
       return "Mia";
    }
}

name attribute is also supported:

Works pretty well for me, but noticed a few things worth fixing.

There is compilation problem https://github.com/redhat-developer/quarkus-ls/runs/6632720210?check_suite_focus=true#step:8:142 you miss to define this method since you add globalVariable parameter (you define a new assertResolver by calling false for globalVariable).

Great job @AlexXuChen !
