I'm trying to figure out if there's a way to avoid GJS exiting when there
are operations going on, like a watch on a file, or folder, without
bothering the main Gtk loop or `imports.mainloop.run()`
What I'd really like to do, is to understand if any other part of the code
started already a loop but I cannot find a way to reach
`g_main_loop_is_running()` via GJS and using `null` to receive the context,
when I should also pass the value `isRunning` makes little sense to me ...
'cause I don't know upfront if I want the default context flagged as
running or not.
The `Gtk.main_level()` gives me 0 even if `imports.mainloop.run()` has
never been called, and it gives me 1 or more even if a `Gtk.main_quit()`
has been invoked after.
Registering a callback in the mainloop also doesn't prevent GJS from
exiting before it's triggered.
I've tried to use `Gio.Application` with a dummy listener and using
`app.hold()` but the moment I follow that command by `app.run([])` nothing
after happens, so I can't set this thing up as it unless I do it after
another event has been scheduled.
This makes sense because `hold` and `release` are explicit in their intent,
but I feel like there's no way to do what I'm trying to do.
Let's say this is my `gjs-info` program
```gjs
#!/usr/bin/env gjs
const Gio = imports.gi.Gio;
let fd = Gio.File.new_for_path(ARGV[0]);
fd.query_info_async('*', Gio.FileQueryInfoFlags.NOFOLLOW_SYMLINKS, null,
null, (source, result) => {
let info = source.query_info_finish(result);
print(info);
});
// if I write this, it will hang
// if I don't, it will exit
// imports.mainloop.run();
```
considering this is an example and what I'm trying to do has many nested
asynchronous operations and not just one, how could I prevent GJS from
exiting the program before I have results?
Thanks for any sort of hint/outcome.
