[SOLVED] How do you unregister snippets in Ace Editor?

How do you unregister snippets in Ace Editor?

I can register the snippets...

var editor = ace.edit("editor");
var snippetManager = ace.require("ace/snippets").snippetManager;
var snippetText = "snippet vfx\n\t<visalforce>\n\t\t$1\n\t</visalforce>";
var snippets = snippetManager.parseSnippetFile(snippetText);
snippetManager.register(snippets);

editor.setOptions({
    enableBasicAutocompletion: true,
    enableSnippets: false
});

But, the unregister just does not work and there is almost zero documentation or samples on the inter-webs...but I keep trying variations of this...

snippetText = "snippet vfx\n\t<visalforce>\n\t\t$1\n\t</visalforce>";
snippets = snippetManager.parseSnippetFile(snippetText);
snippetManager.unregister(snippets);

And it does not work. The snippets are still available in the editor.

Solution

It works if you pass the same object for insert and remove, see this example:

<script src="https://cdn.jsdelivr.net/npm/ace-builds/src-noconflict/ace.js"></script>
<script src="https://cdn.jsdelivr.net/npm/ace-builds/src-noconflict/ext-language_tools.js"></script>
<script>
  var editor = ace.edit();
  editor.container.style.height = "100px";
  document.body.append(editor.container);
  var snippetManager = ace.require("ace/snippets").snippetManager;
  var snippetText = "snippet vfx\n\t<visalforce>\n\t\t$1\n\t</visalforce>";
  var snippets = snippetManager.parseSnippetFile(snippetText);
  snippetManager.register(snippets);

  editor.setOptions({
    enableBasicAutocompletion: true,
    enableLiveAutocompletion: true,
    enableSnippets: true
  });
  
  function removeSnippets() {
    snippetManager.unregister(snippets);
  }
  function addSnippets() {
    snippetManager.register(snippets);
  }
</script>

<button onclick=removeSnippets()>remove snippets</button>
<button onclick=addSnippets()>add snippets</button>
