Unscrewed

Utility for making and updating a data fetcher component of your project.

Install

pip install unscrewed

Usage

First prepare a registry.yaml file, like the one in unscrewed/tests/testreg_registry.yaml. Put it in your package, say in the your_package directory (that contains the __init__.py file). Maybe call it registry.yaml.

In some module, say your_package/data.py

import pkg_resources

import unscrewed

_config_file = pkg_resources.resource_filename("your_package", "registry.yaml")
fetcher = unscrewed.Fetcher(_config_file)

Say you have a file my_data_file.nii configured in your registry.yaml file above.

Now you can fetch it like this:

from your_package.data import fetcher

fname = fetcher('my_data_file.nii')
