VSCODE snippets : Force intellisense after only one character pressed

Question

I'm new to VSCode and I want to test it to compare with my sublime text configuration. I want to create a very simple snippet that allow me to write ruby code <%= %> when I only press < key.

Here is my snippet's code :

    "My snippet": {
        "prefix": "<",
        "body": [
            "<%= $1 %>"
        ],
        "description": "My snippet"
    }

So this code works but I have to press Ctrl+Space in my file to show the IntelliSense list (with my snippet). I just want to press < and Tab to complete this, not to press Ctrl+Space always.

Do you know if there's a configuration to do it ?

Thanx

Answer 1

It is a long time since your question, but I think it may help others.

In settings you need to enable editor.tabCompletion, then you can press tab even if there is no IntelliSense.

Answer 2

To have the snippet auto-injected into the VS Code Editor when you press Tab after the prefix (even this is only one character), you need to set the editor.tabCompletion setting to onlySnippets, neither off nor on.

    "editor.tabCompletion": "onlySnippets",

personally, I think this is a very strange behavior, and that, in theory, with the value on the tabCompletion option should also work. but somehow this option works like that, at least for me.
