pipelib 0.0.0

A command line client and functions for collation.

Pipelib

Pipelib is a library for creating pipelines. You can parse, compare, and order iterables. With Pipelib you can:

1. Create a custom pipeline to parse and compare version strings
2. Use a collection of provided sorting functions for custom sorts.
3. Assemble different processing blocks to pre-process inputs first.

The initial ideas came from Singularity Registry HPC (shpc) that had a need to parse and compare version strings from docker container tags.

Design

import pipelib.main.steps as steps
import pipelib.main.pipeline as pipeline

# A pipeline to process a list of strings
steps = (

   # A step that converts everything to lowercase
   steps.AllLowercase(),

   # step that includes anything with "two"
   (steps.ExcludeFilter(), {"filters": ['two']})
)

# Strings to process
items = ['item-ONE', 'item-TWO', 'item-two-THREE']

p = pipeline.Pipeline(steps)

# The updated and transformed items
updated = p.run(items)
# ['item-one']

TODO

• automated discovery of steps
• automated testing for structure / output of each test
• docstrings should have examples to show usage
• custom version parsing / comparson class
• pipeline steps will need a way to sort / compare / filter
