Contrib Widget Types
|
||
|
|
====================
|
||
|
|
|
||
|
|
Contrib libraries, or widget types, are extra snippets of code you can use.
|
||
|
|
Some are for less common hardware, and other were contributed by Vicious users.
|
||
|
|
The contrib directory also holds widget types that were obsoleted or rewritten.
|
||
|
|
Contrib widgets will not be imported by init unless you explicitly enable it,
|
||
|
|
or load them in your ``rc.lua``.
|
||
|
|
|
||
|
|
Usage within Awesome
|
||
|
|
--------------------
|
||
|
|
|
||
|
|
To use contrib widgets uncomment the line that loads them in ``init.lua``.
|
||
|
|
Or you can load them in your rc.lua after you require Vicious:
|
||
|
|
|
||
|
|
.. code-block:: lua
|
||
|
|
|
||
|
|
local vicious = require"vicious"
|
||
|
|
vicious.contrib = require"vicious.contrib"
|
||
|
|
|
||
|
|
Widget Types
|
||
|
|
------------
|
||
|
|
|
||
|
|
Most widget types consist of worker functions that take the ``format`` argument
|
||
|
|
given to :lua:func:`vicious.register` as the first argument,
|
||
|
|
``warg`` as the second, and return a table of values to insert in
|
||
|
|
the format string. But we have not insisted on this coding style in contrib.
|
||
|
|
So widgets like PulseAudio have emerged that are different. These widgets
|
||
|
|
could also depend on Lua libraries that are not distributed with the
|
||
|
|
core Lua distribution. Ease of installation and use does not necessarily
|
||
|
|
have to apply to contributed widgets.

|
vicious.contrib.ac

||
|
|
under ``/sys/class/power_supply/`` and should have a file called ``online``.

||
|
|
* Returns ``{"On"}`` if AC is connected, else ``{"Off"}``.
