Hot to parse .ini file in extension

[Stefano Ciancio <s ciancio gmail com>]

Hi all,

I am developing a little extension for Gnome Shell and I need to read 
and parse an .ini file from my system.

I find a GLib object (GKeyFile) that would be suitable for this, but I 
cannot find doc, code, example on how to use it in shell.

With the code below:

const GLib = imports.gi.GLib;
let kf = new GLib.KeyFile();

I obtain the following error:

    JS ERROR: !!!   Exception was: Error: Unable to construct boxed 
type KeyFile since it has no zero-args <constructor>, can only wrap an 
existing one
    JS ERROR: !!!     lineNumber = '0'
    JS ERROR: !!!     fileName = '"gjs_throw"'
    JS ERROR: !!!     stack = '"("Unable to construct boxed type 
KeyFile since it has no zero-args <constructor>, can only wrap an 
existing one")@gjs_throw:0 test js:12"'
    JS ERROR: !!!     message = '"Unable to construct boxed type 
KeyFile since it has no zero-args <constructor>, can only wrap an 
existing one"'
Error: Unable to construct boxed type KeyFile since it has no zero-args 
<constructor>, can only wrap an existing one

Can you help me?

Thanks,
