drakeutil

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?
