I've got an app that needs to read and parse a data file (a RADIUS
dictionary, not a Python dictionary but a flat file). I want to
include this file in my egg so I don't have to depend on the OS having
RADIUS installed.
In the application's top-level setup.py, I add my data/ subdir to the
package_data list:
package_data={'bianca': ['i18n/*/LC_MESSAGES/*.mo', 'data/*']},
and see that the files in data/ get added to my egg. Good so far.
What path do I use to reference that file for reading? Again, I am
trying to avoid hard-coded absolute filesystem paths. But trying paths
like:
freeradius_dictionary
/data/freeradius_dictionary
/bianca/data/freeradius_dictionary
/bianca/freeradius_dictionary
didn't work for me: file not found.
What's the pattern for paths to files that live inside eggs, rather than
on the larger filesystem? Is there some PATH I need to specify to the
app or Pylons? Something else?
from pkg_resources import resource_filename
path = resource_filename('bianca', 'data/freeradius_dictionary')
If data would have been a python package, which I suppose it's not, then:
path = resource_filename('bianca.data', 'freeradius_dictionary')
HTH,
