Resource storage

Similar to setuptools.pkg_resources, but with extended functionality

class pyaltt2.res.ResourceStorage(resource_dir='.', mod=None)

Resource storage loader

Usage example:

from pyaltt.res import ResourceStorage from functools import partial

rs = ResourceStorage(mod=mymod)

rq = partial(rs.get, resource_subdir=’sql’, ext=’sql’)

rq(‘object.select.data’) - will load resource from (will try all variations until file is found):

  • sql/object.select.data.sql
  • sql/object/select.data.sql
  • sql/object/select/data.sql

Resource is loaded once and cached forever.
