Python Function Filename Wrapper

Python Function Filename Wrapper (pyfnfn for short; and formerly python-filewraps) is a small Python decorator snippet which extends the input entry point of any Python functions to accept file names as input arguments given that the function already accepts file-like objects.

This is a work in progress and should support python3.4 and newer. We dropped support for earlier versions of Python due to their support reaching end-of-life.

The earlier version (v0.6) of pyfnfn also supports python2.7.

Testing and Examples of Usage

This project uses the built-in unittest module to test the implementation. To run the test, execute the following command:

./runtest.sh

Also, in particular, the test file test/test_wrapper.py contains a few examples of how @fnfnwrap can be utilized.
