Activity Team/Activity Development Fedora 17
Develop an Activity under Fedora 17
Developing an activity under Fedora has never been so easy. Here are the most basic steps to get you started.
Install Fedora 17
Follow the instructions at the Fedora page and install Fedora or run it in a virtualized environment.
Now install Sugar, on Fedora this is Sugar 0.96:
yum groupinstall sugar-desktop
For running Sugar under GNOME you can use the 'sugar-emulator' install the package:
yum install sugar-emulator
Start the sugar emulator
You can start the Sugar emulator from the terminal, like:
To approximate the screen size proportions of an XO:
sugar-emulator -i 832x624
Or you can run it from your launcher like any other application:
sed -i 's/sugar-emulator/& -i 832x624/' /usr/share/applications/sugar-emulator.desktop
or in the Nautilus graphical file browser,
- right click the Sugar entry in
- click the 'Properties' menu item,
- and add
-i 832x624to the 'Command:' entry box.
(Note: The images below were taken with the default 800x600 resolution of Sugar in a window.)
Modify an Activity
The Activities you installed earlier with the 'groupinstall' command are installed under '/usr/share/sugar/activities/'. For developing it is easier to have them available in a user accessible part of the system. Sugar does look in the $HOME/Activities folder for Activities. The folder has to be named to end with '.activity'.
Start a terminal and create the folder in your $HOME directory and change into it:
cd mkdir Activities cd Activities/
Clone the HelloWorld activity (in the folder helloworld.activity):
git clone git://git.sugarlabs.org/hello-world/mainline.git helloworld.activity
If you know restart the sugar-emulator the activity will be available. You can favorite it in the activity-list view in the Home view.
So the first fun thing to do is to change the HelloWorld Activity to welcome yourself. Just change the activity.py file in the Activity folder with your favorite editor and restart the Activity. You do not need to restart the emulator for that.
If you made it that far yo have been made a big step to become an Activity developer using the tools available in Fedora 17. I hope you enjoyed it.
