Usage within Awesome
|
|
====================
|
|
|
|
To use Vicious with awesome_, install the package from your operating system
|
|
provider, or download the source code and move it to your awesome
|
|
configuration directory in ``$XDG_CONFIG_HOME`` (usually ``~/.config``)::
|
|
|
|
git clone https://github.com/vicious-widgets/vicious.git
|
|
mv vicious $XDG_CONFIG_HOME/awesome/
|
|
|
|
Vicious will only load modules for widget types you intend to use in
|
|
your awesome configuration, to avoid having useless modules sitting in
|
|
your memory.
|
|
|
|
Then add the following to the top of your ``rc.lua``:
|
|
|
|
.. code-block:: lua
|
|
|
|
local vicious = require("vicious")
|
|
|
|
vicious.register
|
|
----------------
|
|
|
|
Once you create a widget (a textbox, graph or a progressbar),
|
|
call ``vicious.register`` to register it with Vicious:
|
|
|
|
.. lua:function:: vicious.register(widget, wtype, format, interval, warg)
|
|
|
|
Register a widget.
|
|
|
|
:param widget: awesome widget created from
|
|
``awful.widget`` or ``wibox.widget``
|
|
|
|
:param wtype:
|
|
either of
|
|
|
|
* Vicious widget type: any widget type
|
|
:ref:`provided by Vicious <widgets>` or customly defined.
|
|
* ``function``: custom function from your own
|
|
awesome configuration can be registered as widget types
|
|
(see :ref:`custom-wtype`).
|
|
|
|
:param format:
|
|
either of
|
|
|
|
* string: ``$key`` will be replaced by respective value in the table
|
|
``t`` returned by the widget type, i.e. use ``$1``, ``$2``, etc.
|
|
to retrieve data from an integer-indexed table (a.k.a. array);
|
|
``${foo bar}`` will be substituted by ``t["{foo bar}"]``.
|
|
* ``function (widget, args)`` can be used to manipulate data returned
|
|
by the widget type (see :ref:`format-func`).
|
|
|
|
:param interval: number of seconds between updates of the widget
|
|
(default: 2). See :ref:`caching` for more information.
|
|
|
|
:param warg: arguments to be passed to widget types, e.g. the battery ID.
|
|
|
|
``vicious.register`` alone is not much different from awful.widget.watch_,
|
|
which has been added to Awesome since version 4.0. However, Vicious offers
|
|
more advanced control of widgets' behavior by providing the following functions.
|
|
|
|

|
|
|
|
.. lua:function:: vicious.unregister(widget, keep)

|
|
``awful.widget`` or ``wibox.widget``
|
|
:param keep: if true suspend ``widget`` and wait for activation
|
|
:type keep: bool
|
|
|
|
vicious.suspend
|
|
---------------
|
|
|
|
.. lua:function:: vicious.suspend()

|
|
|
|
.. lua:function:: vicious.activate([widget])
