Plugins are simple python scripts which use the API from Ubuntu Tweak. They are easy to write and well integrated with Ubuntu Tweak.
Currently the API is not stable yet, but I hope you can start to write something and give some feedback to me so I can improve Ubuntu Tweak.
Add the following PPA and upgrade to 0.6.0 (WARNING: this is not a completed version and will lack some features): https://launchpad.net/~tualatrix/+archive/next
PyGObject: the old PyGtk is not supported
- To test plugins more quickly, use this command to load from terminal:
ubuntu-tweak -m "ClassName"
As you can see from the screenshot, Ubuntu Tweak consists of four main parts: "Overview", "Tweaks", "Admins" and "Janitor".
Every part is plug-able, this enables Ubuntu Tweak as a powerful and flexible system/desktop utility.
The "Overview" page is the place to show some quick informations and tips, it is called "Clip". Each clip shows only one kind of information, such as "Hardware Info", "Desktop Info". Users can manage the clips which he/she want to see when start with Ubuntu Tweak, and developer can write a new Clip.
In the Preference Dialog, you can enable/disable the clips, adjust the order of Clips, or install a new clip.
The Tweaks/Admins page is the place where you can find the things to "tweak" your system.
If your plugin is making configuration changes (for example by exposing keys in GConf), you should add it to 'Tweaks'. If it is doing some other task (such as backups, updates and so on), it should be put under 'Admins'.
Just like the Preferences of Overview, there are preferences for Tweaks/Admins too. Currently you can only enable/disable the third-party plugins.
Ubuntu Tweak 0.6.0 comes with a powerful "Computer Janitor" to replace the formal old pre-installed computer-janitor, but with a more simple and easy-to-use user interface.
Let's start with an example.
Examples of Plugin
Example 1 (Tweaks/Admins)
In the first example, I will add some options that deal with bluetooth file sharing.
If you've run Ubuntu Tweak 0.6 before, two folders will be created under $HOME/.config/ubuntu-tweak, they are "tweaks", "admins". These are the user plugin folders.
Create a file named "bluetoothsettings.py"(or click to download it) and put it into $HOME/.config/ubuntu-tweak/tweaks/, then fill it with the following:
# Your name, email and other copyright information from gi.repository import Gtk #Don't support PyGtk from ubuntutweak.gui.containers import TablePack # TablePack is a container to pack any numbers of widgets from ubuntutweak.modules import TweakModule # Subclass this Module then it will become a plugin of Ubuntu Tweak from ubuntutweak.factory import WidgetFactory # Use to create the setting related widget easily class BluetoothSettings(TweakModule): __title__ = _('Bluetooth Settings') __desc__ = _('Tweak some hidden bluetooth settings') __icon__ = 'bluetooth' # The icon name, currently don't support path to image __category__ = 'system' # the category __author__ = 'Your Name <firstname.lastname@example.org>' __url__ = 'Your home page' __url_title__ = 'The title of Home page' def __init__(self): TweakModule.__init__(self) # WidgetFactory will return a tuple of widgets box = TablePack(_("Bluetooth Options"), ( WidgetFactory.create("CheckButton", label=_('Share Public directory over Bluetooth'), key="/desktop/gnome/file_sharing/bluetooth_enabled", backend='gconf', # GSettings will support in the future enable_reset=True), WidgetFactory.create("CheckButton", label=_("Whether to notify about newly received files"), key="/desktop/gnome/file_sharing/bluetooth_notify", backend='gconf', enable_reset=True), WidgetFactory.create("CheckButton", label=_("Whether to allow Bluetooth clients to write files."), key="/desktop/gnome/file_sharing/bluetooth_allow_write", backend='gconf', enable_reset=True), WidgetFactory.create('ComboBox', label=_('When to accept files sent over Bluetooth'), key='/desktop/gnome/file_sharing/bluetooth_accept_files', enable_reset=True, backend='gconf', texts=[_('Always'), _('Bonded'), _('Ask')], values=["always", "bonded", "ask"]), )) self.add_start(box, False, False, 0)
Now save the file, open Ubuntu Tweak, and you see what has been added? Yes, the Bluetooth Settings!
Click it! See what you have done with just a few lines of code? A complete Bluetooth tweaking feature is almost there.
Each option automatically has a "Reset" button on the right side, so that the user can reset that option to its default value.
I'm not good at the API design, so if you have some suggestions, please tell me, let's make it better. You can find my contact information here: http://blog.ubuntu-tweak.com/about
