"""
This plugin lets you execute a command, to notify you from new important
messages.
Installation and configuration
------------------------------
You need to create a plugin configuration file. Create a file named :file:`simple_notify.cfg`
into your plugins configuration directory (:file:`~/.config/poezio/plugins` by
default), and fill it like this:
First example:
.. code-block:: ini
[simple_notify]
command = notify-send -i /path/to/poezio/data/poezio_80.png "New message from %(from)s" "%(body)s"
Second example:
.. code-block:: ini
[simple_notify]
command = echo \\<%(from)s\\> %(body)s >> some.fifo
delay = 3
after_command = echo >> some.fifo
You can put any command, instead of these ones. You can also use the
special keywords ``%(from)s`` and ``%(body)s`` that will be replaced
directly in the command line by the author of the message, and the body.
The first example shown above will display something like this:
.. figure:: ../images/simple_notify_example.png
:alt: Simple notify example
The second example will first write the author and the message in a
fifo, that fifo can locally be read by some other program (was tested
with the xmobar PipeReader command, which displays what is read from a
fifo into a status bar. Be careful, you have two different fifos in
that case, don’t get confused). The :term:`delay` and :term:`after_command` options
are used to erase/delete/kill the notification after a certain
delay. In our example it is used to display an empty message in our
xmobar, erasing the notification after 3 seconds.
Third example:
.. code-block:: ini
[simple_notify]
command = notify-send -i /path/to/poezio/data/poezio_80.png "New message from %(from)s" "%(body)s"
muc_too = true
If present and set to ``True``, the ``muc_too`` option will also trigger a
notification when a new message arrives on a Multi User Chat you've joined.
.. note:: If you set the :term:`exec_remote` option to ``true`` into the
main configuration file, the command will be executed remotely
(as explained in the :ref:`link-plugin` plugin help).
Options defined
---------------
.. glossary::
:sorted:
command
The command to execute (with special keywords ``%{from}s`` and ``${body}s``)
delay
Delay after which :term:`after_command` must be executed.
after_command
Command to run after :term:`delay`. You probably want to clean up things.
muc_too
Boolean indicating whether new messages in Multi User Chat rooms should
trigger a notification or not.
