Convert IPython Jupyter Notebooks to CWL tool

IPython2CWL

IPython2CWL is a tool for converting IPython Jupyter Notebooks to CWL (Common Workflow Language) Command Line Tools by simply providing typing annotation.

from ipython2cwl.iotypes import CWLFilePathInput, CWLFilePathOutput
import csv
input_filename: 'CWLFilePathInput' = 'data.csv'
with open(input_filename) as f:
    csv_reader = csv.reader(f)
    data = [line for line in csv_reader]
number_of_lines = len(data)
result_file: 'CWLFilePathOutput' = 'number_of_lines.txt'
with open(result_file, 'w') as f:
    f.write(str(number_of_lines))

IPython2CWL is based on repo2docker, the same tool used by mybinder. Now, by writing Jupyter Notebook and publishing them, including repo2docker configuration, the community can not only execute the notebooks remotely but also to use them as steps in scientific workflows.
