In Suski's blog I saw a question on whether developing GNOME apps would be possible in CoffeeScript. The answer is yes. I wrote a quick example back in Desktop Summit:
# GObject Introspection APIs are available from imports.gi.Modulename
Gtk = imports.gi.Gtk
# For GNOME 3.2+ this should be Gtk.init null, 0
Gtk.init 0, null
win = new Gtk.Window
type: Gtk.WindowType.TOPLEVEL
win.set_border_width 10
win.connect "destroy", (widget) ->
Gtk.main_quit()
button = new Gtk.Button
label: "Hello, world"
button.connect "clicked", ->
button.set_label "Bar"
win.add button
button.show()
win.show()
Gtk.main()
Gjs doesn't run CoffeeScript directly, so you need to convert this before running:
$ coffee -c window.coffee
$ gjs window.js
You should see something similar to:
