$ jpl -v -p examples/jiggy-playbook.yml
   __        ______      __
  /\ \      /\  == \    /\ \
 _\_\ \     \ \  _-/    \ \ \____

[F01] FunctionSourceExists - get-weekday:         FAILED      Declared path to function: `examples.utils.dates.GetWeekdayTask` does not exist.

Via python client with .validate()

import jpl

>>> client = jpl.JiggyPlaybookLint(path="path/to/playbook")
>>> result = client.validate()

The validate() method will return a tuple

The tuple denotes the validity of the playbook and the failing rules as JiggyRule objects

(False, [<JiggyRule: F01>, <JiggyRule: F01>, <JiggyRule: F01>, <JiggyRule: F01>, <JiggyRule: F01>, <JiggyRule: F01>])

Overview

A JiggyPlaybook is broken down into chunks

• Playbook

  • The entire .yml constitutes the "playbook"

• Pipeline

  • The key pipeline including all tasks constitutes the "pipeline"

• Task

  • Tasks are chunks of a pipeline having the below attributes:
    • name
    • description
    • function which contains source, params, output
    • requires

name: Hello, world!
author: [e-mail]

version: 0.0.1

pipeline:
  runner: sequential
  secrets:
    location: examples/secrets/.env-example
    source: jiggy.EnvSecrets
  tasks:

  - name: print-something
    description: Print something
    function:
      source: examples.utils.string_manipulation.PrintThis
      params:
      - type: str
        value: 'THIS PIPELINE IS GREAT'
      output: null
    requires: null

Rules

Etymology:

JiggyRule - JiggyRule.rule consists of 3 characters (i.e.) X01

• X: (char) - letter describes corresponding ruleset

• 0: (digit) - incrementing based on third digit

• 0: (digit) - incrementing

Examples:

Rule: PlaybookHasName

• rule.rule = I (info) 0 (base 10) 1 (rule number 1)

Rule: PipelineHasDescription

• rule.rule = P (pipeline) 0 (base 10) 1 (rule number 1)
