For this you should prefer the Gio.Subprocess API. Unfortunately it's too
new to appear in the roojs documentation, but here's the Python
documentation so you can get a sense of how it works:
http://lazka.github.io/pgi-docs/index.html#Gio-2.0/classes/Subprocess.html#Gio.Subprocess
Here are how the examples from your linked StackOverflow question would be
implemented. (I didn't post them there because your question was really
about the main loop, so it wouldn't have been a good answer for SO.)
Sync:
const Gio = imports.gi.Gio;
let subprocess = new Gio.Subprocess({
argv: ['/bin/ls'],
flags: Gio.SubprocessFlags.STDOUT_PIPE,
});
subprocess.init(null);
let [, out] = subprocess.communicate_utf8(null, null);
print(out);
Async:
const Gio = imports.gi.Gio;
const Mainloop = imports.mainloop;
let subprocess = new Gio.Subprocess({
argv: ['/bin/ls'],
flags: Gio.SubprocessFlags.STDOUT_PIPE,
});
subprocess.init(null);
subprocess.communicate_utf8_async(null, null, (obj, res) => {
let [, out] = obj.communicate_utf8_finish(res);
print(out);
Mainloop.quit('main');
});
Mainloop.run('main');

Philip
