<title>Script Writing</title>
|
|
|
|
<para>Scripting allows you to extend &amarok; easily without changing the main codebase. Scripts are similar to plugins, but instead of a dedicated plugin API they use &amarok;'s DCOP interface for communication. This makes it possible to write scripts in almost any programming language, like Ruby, Python or PHP. Not only can you create scripts in classic scripting languages, but also in compiled languages like C++ or plain C. Additionally, &amarok; can notify the scripts on special events and make them react accordingly. This notification system will be explained later in this section.</para>
|
|
|
|
<sect2 id="script-bindings">
|
|
<title>Bindings</title>
|
|
|
|
<para>It is possible to write simple scripts that do not need user interaction, and it's also possible to make scripts with comfortable GUIs that act like little applications of their own. For GUI programming one of the many bindings which KDE provides can be used, for instance RubyQt, a Qt library binding for Ruby. However, it is worth noting that not every user has all available bindings installed. If you decide to use a binding, try to use one of the relatively wide spread ones (e.g. RubyQt or PyQt).</para>
|
|
|
|
<para>In order to provide some feedback when a script fails to run due to a missing dependency, please check in your script if the module you want to include really exists. If the dependency is missing, you should catch the error and show an information dialog using the "kdialog" command line tool, so that the user learns why the script fails to run.</para>
|
|
|
|
<para>This example shows how to catch a missing dependency in Ruby:</para>
|
|
|
|
<programlisting>
|
|
begin
|
|
require 'Korundum'
|
|
rescue LoadError
|
|
error = 'Korundum (KDE bindings for ruby) from tdebindings v3.4 is required for this script.'
|
|
`kdialog --sorry '#{error}'`

<title>Getting Started: The Templates</title>

|
<para>&amarok; provides template scripts for several languages in the <filename class="directory">scripts/templates/</filename> directory. You can use these scripts as a basis for your own scripts, and extend them with the functionality you need. You'll notice that scripting is actually quite straightforward; For instance if you know to program a bit in Python, making your own script won't take you long.</para>

<title>Controlling &amarok; With DCOP</title>
|
|
|
|
<para>Scripts can control Amarok by calling some of its DCOP functions. The easiest way to invoke a DCOP function is by using the "dcop" command line utility, which is part of every KDE distribution.</para>
|
|
|
|
<para>Here is an example for increasing the master volume:</para>
|
|
|
|
<programlisting>dcop amarok player volumeUp</programlisting>
|
|
|
|
<para>Most scripting languages allow to execute external programs, with a function like exec(). This way the "dcop" utility can be invoked easily. Here is a simple Python example:</para>
|
|
|
|
<programlisting>
|
|
import os
|
|
os.system("dcop amarok player volumeDown")

|
|
<title>Notifications</title>
|
|
|
|
<para>&amarok; sends notifications to all running scripts by writing strings to their stdin channel. The script should therefore constantly monitor stdin, and react accordingly to each of the possible events. Scripts may also choose to ignore any event they don't have a use for.</para>
|
|
|
|
<para>The following notifications are sent by &amarok;:</para>
|
|
|
|
<programlisting>
|
|
<cmdsynopsis><command>configure</command></cmdsynopsis>
|
|
Tells the script to show its configuration dialog. The script must handle the
|
|
storing and loading of configuration options by itself. When a script is
|
|
started, Amarok sets its working directory to the folder where all data
|
|
should be stored.

<programlisting>

<cmdsynopsis><command>engineStateChange:</command><arg>empty|idle|paused|playing</arg></cmdsynopsis>

</programlisting>
|
|
|
|
<programlisting>
|
|
<cmdsynopsis><command>trackChange</command></cmdsynopsis>

query further information about the track, e.g. metadata and the length.

</programlisting>
|
|
|
|
<programlisting>
|
|
<cmdsynopsis><command>volumeChange</command><arg>newVolume</arg></cmdsynopsis>

Signals a change of the master volume level. The volume is an integer with a

range of 0-100.

</programlisting>
|
|
|
|
<programlisting>
|
|
<cmdsynopsis><command>customMenuClicked:</command><arg>submenu itemTitle paths</arg></cmdsynopsis>
|
|
Returns the paths to selected files in the playlist when the custom playlist
|
|
context menu item is clicked. The submenu and itemTitle are also returned for
|
|
identification purposes in case a script is listening for multiple notifications.
|
|
To insert an item into the context menu use the DCOP call
|
|
'dcop amarok script addCustomMenuItem( submenu itemTitle )'. To remove an
|
|
item from the context menu use the DCOP call
|
|
'dcop amarok script removeCustomMenuItem( submenu itemTitle )'.
