ResourcePackage is a mechanism for automatically managing resources
(i.e. non-Python files: small images, documentation files, binary data)
embedded in Python modules (as Python source code), particularly for
those wishing to create re-usable Python packages which require their
own resource-sets.
ResourcePackage allows you to set up resource-specific sub-packages
within your package. It creates a Python module for each resource
placed in the resource package's directory during development. You can
set up these packages with a simple file-copy and then use the resources
saved/updated in the package directory like so:
from mypackage.resources import open_icon
result = myStringLoadingFunction( open_icon.data )
ResourcePackage scans the package-directory on import to refresh module
contents, so simply saving an updated version of the file will make it
available the next time your application is run.
When you are ready to distribute your package, you need only replace the
copied file with a dummy __init__.py to disable the scanning support and
eliminate all dependencies on resourcepackage (that is, your users do
not need to have resourcepackage installed once this is done). Users of
your packages do not need to do anything special when creating their
applications to give you access to your resources, as they are simply
Python packages/modules included in your package's hierarchy. Your
package's code (other than the mentioned __init__.py) doesn't change.
Note: there is code in resource package to allow you to manually refresh
your package directories w/out copying in __init__.py. I haven't yet
wrapped that as a script, but intend to for the 1.0 release.
ResourcePackage is currently in 1.0 alpha status, it appears to work
properly, but it has only had minimal testing. You can get the
distribution from the project page at:
http://sourceforge.net/projects/resourcepackage/
I'm interested in any bug reports, enhancement requests or comments.
Enjoy all,
Mike Fletcher
