Hi, I really understand about how confusing and difficult it is to write a
gnome shell extension. I myself have trouble understanding how things work
in gnome js, and gnome have no simple and easy documentation. Therefore I
only rely on how others did their extension and tried to copy from that. I
can only share you some tips:

   - Try to learn more about javascript, I don't know on what level your
   understanding is, but you might surprised on what javascript could do,
   especially on object-oriented programming. You could read on it
here<http://bonsaiden.github.io/JavaScript-Garden/>
   . But then again, gnome uses its own object wrapper for OOP which is
   easier to use, so you could skim through it.
   - Gnome js is javascript binding for gnome framework, which originally
   written in C, so basic grasp on gnome is a must too (e.g. how to make
   button, drop down menu, text input).
This<https://developer.gnome.org/gnome-devel-demos/3.12/js.html.en>
    contains straightforward tutorials and documentation on how to make
   gnome application using javascript.
   - Looking Glass is the most powerful tool to get UI component you want
   to change. You could also manipulate the object directly from its console.
   - If you want to add some component (like drop down menu, etc) but don't
   know what class to implement, refer to mathematical coffee, and the
   original files that usually on /usr/share/gnome-shell/js/ui. You could
   learn what class emit what event on that too.
   - Most often you need to use other gnome library function (e.g. get
   webpage, write to file),
this<http://www.roojs.com/seed/gir-1.2-gtk-3.0/seed/>

    has documentation at least the objects and function names, to learn
   what does what you need to search the C documentation on
   developer.gnome.org
   - Learn from similar works. You could learn others' approach to make
   their extension.

I'd say there's no straightforward tutorial that teaches you on how to make
complex extension (and heck, even the simplest, like making drop down menu
extension). That Gnome 3 development book looks like a good start, but I
can't recommend it since I've never read it.

This is a big problem for everybody who wants to write their own extension,
to which I want to do some documentation on it, but I don't know where to
start. Anyone have a suggestion?
