unpacking GVariant in javascript

Question

I have an array stored as a GVariant of type a(ss) in GSettings, that I want to use in a Cinnamon Applet. I can retrieve the value successfully using the following code:

let schema = schema_source.lookup(SCHEMA_NAME, false);
let settings = new Gio.Settings({ settings_schema: schema });
let my_value = settings.get_value('myvalue');

but I can't unpack it. As far as I can see, I will probably need to unpack it using a GVariantIter structure, but the documentation is limited, and I can't find the correct interface in the gjs API (if, indeed, it exists). Does anyone know how to do it?

Thanks!

edit: my schema looks like this:

<key type="a(ss)" name="myvalue">
    <default>[]</default>
    <summary>an array of (string, string) tuples</summary>
    <description></description>
</key>

For the time being I'm using an external JSON file to store settings, but it's not a 100% satisfactory solution. I suppose I could maintain two as-type variables, and keep them aligned, but there must be a way to do this properly, right?

Answer 1

A bit late, but my_value.unpack() works absolutely fine.

my_value.deep_unpack() will recursively unpack the arrays and their elements.
