Records the inputs and outputs of scripts

Project description

Build Status Documentation Status

Pirec is a Python package for wrapping scripts so that their inputs and outputs are preserved in a consistent way and results are recorded.

Example

from pirec import call, record, pipeline
from pirec.artefacts import TextFile


@record()
def pipeline_stage_1(f):
    call(['/bin/cat', f.filename])


@record()
def pipeline_stage_2(f):
    call(['/bin/cat', f.filename])


def my_pipeline(file1, file2):
    pipeline_stage_1(file1)
    pipeline_stage_2(file2)


def example_pipeline():
    pipeline.run(
        'example',
        my_pipeline,
        '/my/data/directory',
        TextFile('month00/data.txt'), TextFile('month12/data.txt')
    )


if __name__ == '__main__':
    example_pipeline()

Installation

Requirements
