5 Usage

8 You can ``register`` Yawn to get a set of widgets, or ``attach`` it to
9 an existent widget.
10
11 ### register
12
13     yawn = lain.widgets.yawn(id, args)
14
15 - ``id``
16
17     An integer that defines the WOEID code of your city.
18     To obtain it you can google 'yahoo weather %CITYNAME%' and follow the first link.
19     It will look like:
20
21         http://weather.yahoo.com/united-states/california/san-diego-2487889/
22
23     and the last number in that link will be the ID you need.
24
25 - ``args``
26
27     A required table which can contain:
28
29     Variables | Meaning | Type | Possible values | Default value
30     --- | --- | --- | --- | ---

33     `settings` | User settings | function | function | empty function
34
35     `settings` can use strings `forecast`, `units`, and can modify `notification_preset` table, which
36      will be the preset for the naughty notifications. Check [here](http://awesome.naquadah.org/doc/api/modules/naughty.html#notify) for the list of variables it can contain.
37
38 The function `register` creates an imagebox icon and a textbox widget. Add them to you wibox like this:
39
40     right_layout:add(yawn.icon)
41     right_layout:add(yawn.widget)
42
43 Hovering over ``yawn.icon`` will display the notification.
44
45 ### attach
46
47     lain.widgets.yawn.attach(widget, id, args)
48
49 Arguments:
50
51 - ``widget``
52  
53     The widget which you want to attach Yawn to.
54
55 - ``id``
56
57     Same as in ``register``.
58
59 - ``args``
60  
61    Same as in ``register``.
62
63 Hovering over ``widget`` will display the notification.
64
65 Popup shortcut
66 --------------
67
68 You can also create a keybinding for the weather popup like this:
69
70     awful.key( { "Mod1" }, "w", function () yawn.show(5) end )
71
72 where ``show`` argument is an integer defining timeout seconds.
73
74 Localization
75 ------------
76
77 Default language is English, but Yawn can be localized.
78
79 Move to `localizations` subdirectory and fill `localization_template`.
80
81 Once you're done, rename it like your locale id. In my case:
82
83     $ lua
84     Lua 5.2.2  Copyright (C) 1994-2013 Lua.org, PUC-Rio
85     > print(os.getenv("LANG"):match("(%S*$*)[.]"))
86     it_IT
87     >
88
89 hence I named my file "it_IT" (Italian localization).
90
91 **NOTE:** If you create a localization, feel free to send me! I will add it.
