Vicious widget types are a framework for creating your own widgets.
Before using a widget type *you* need to ensure that a valid source of
information exists.
Usage
-----
To use vicious copy it to the ~/.config/awesome directory, edit
init.lua and comment out all the widgets you don't need from the
"Configure widgets" list. Then add:
To use vicious move it to your awesome configuration directory in
$XDG_CONFIG_HOME (usually ~/.config):
$ mv vicious $XDG_CONFIG_HOME/awesome/
Your first step should be editing init.lua to comment out all the
widget types you don't need from the "Configure widgets" list. It is
not required but I suggest you do so to avoid having useless modules
sitting in your memory.
Then add the following to the top of your rc.lua:
require("vicious")

Custom widget types
-------------------
Use any of the existing widgets as a starting point for your
Use any of the existing widget types as a starting point for your
own. Write a quick worker function that does the work and plug it
in. How data will be formatted, will it be red or blue, should be
defined in rc.lua (or somewhere else, outside the actual widget).
Format functions
----------------
You can use a function instead of a string as the format parameter, so
you are able to check the value returned by the widget type and change
it. You can change the color of the battery widget when it goes below
a certain point, or maybe hide widgets when they return a certain
value or... you get the point.
- Do not confuse this with just coloring the widget, in those cases
standard markup can be inserted into the format string.
The format function will get the widget as its first argument, and a
table with the values otherwise inserted into the format string as its
second argument, and should return the text to be used for the widget.
Example widget
mpdwidget = widget({ type = 'textbox', name = 'mpdwidget' })
vicious.register(mpdwidget,vicious.widgets.mpd,
function (widget, args)
if args[1] == "Stopped" then return ''
else return '<span color="white">MPD:</span> '..args[1]
end
end)
- hides the mpd widget when there is no song playing, executed every
2 seconds (the default interval)
defined in rc.lua (or somewhere else, outside the actual module).
Usage examples
--------------
Remember, beside creating and registering widgets you have to add them
to a wibox in order to display them.
Start with a simple widget, like date. Then build your setup from
there, one widget at a time. Also remember that besides creating and
registering widgets you have to add them to a wibox (statusbar) in
order to actually display them.

mpdwidget = widget({ type = 'textbox', name = 'mpdwidget' })
