How do I get additional help beyond this almanac?
- Looking to get started with the basics of sugar development? Check out Christoph Derndorfer's Activity Handbook.
Now, on to the actual almanac ...
Package: sugar.activity
Package: sugar.graphics
Package: sugar.datastore
MISCELLANEOUS
The tasks below are random useful techniques that have come up as I write code and documentation for this reference. They have yet to be categorized, but will be as a sufficient set of related entries are written.
How do I get the file path for my activity bundle?
In the sugar model, all files needed to run an activity (the python code, icons, etc.) should be located under one directory:
"Every activity in the Sugar environment is packaged into a self-contained 'bundle'. The bundle contains all the resources and executable code (other than system-provided base libraries) which the activity needs to execute. Any resources or executable code that is not provided by the base system just be packaged within the bundle." <ref>OLPC Austria - Activity Handbook for Sugar</ref>
At present, the most direct way to get a handle on the directory where your activity code is saved is to use the activity.get_bundle_path() method. The following code retrieves the bundle path and prints it to screen - you can reuse it and do whatever you like to save files or manipulate data in your activity bundle directory.
from sugar.activity import activity ... print activity.get_bundle_path() ...
How do I get the file path where I can write files programmatically?
The activity package also has a activity.get_activity_root() helper function that gets the root directory where your activity may write files. There are three specific writable subdirectories within your activity root: instance, data and tmp.
from sugar.activity import activity import os ... #print out the root directory where this activity will be writing print activity.get_activity_root() #print out the names of the different root subdirectories to which #I can write. print os.path.join(activity.get_activity_root(), "instance") print os.path.join(activity.get_activity_root(), "data") print os.path.join(activity.get_activity_root(), "tmp")
