Python helpers for the drake workflow language

Project description

Utilities for making life easier in Python with Drake workflows.

Installing

Run pip install drakeutil.

Using

For Python steps inside your workflow include the line:

from drakeutil import *

This will populate the special family of variables INPUT, OUTPUT from the environment. For example:

somefile.out <- somefile.in [python]
    from drakeutil import *
    with open(INPUT) as istream:
        with open(OUTPUT) as ostream:
            for l in istream:
                for word in l.split():
                    print >> ostream, word

In the future we might add more helpers. Can you think of any that would be useful?
