Task executor - balance between Makefile and Gradle.

Task executor - balance between Makefile and Gradle.

THIS PROJECT IS A WORK IN PROGRESS.

Goals: - Define tasks as simple as in Makefile - Reuse code as simple as in Gradle (using extensions that provides tasks. Extensions are installable from PIP) - Simple configuration in Python

Rules

• No hooks eg. task.executeAfter(otherTask), no complex dependencies

• No dynamic tasks names eg. by turning on Publish component it should not create tasks eg. :publishIWAToDockerRegistry (where IWA is the project name)

Usage in shell

Tasks are prefixed always with “:”. Each task can handle it’s own arguments.

Tasks arguments usage

makefile.py

from rkd.syntax import TaskDeclaration, TaskAliasDeclaration
from rkd.standardlib.python import PublishTask

IMPORTS = [
    TaskDeclaration(PublishTask())
]

TASKS = [
    TaskAliasDeclaration(':my:test', [':py:publish', '--username=...', '--password=...'])
]

Example of calling same task twice, but with different input

Notes for this example: The “username” parameter is a default defined in makefile.py in this case.

$ rkd :my:test --password=first :my:test --password=second
 >> Executing :py:publish
Publishing
{'username': '...', 'password': 'first'}

 >> Executing :py:publish
Publishing
{'username': '...', 'password': 'second'}

Example of calling same task twice, with no extra arguments

In this example the argument values “…” are taken from makefile.py

$ rkd :my:test :my:test
 >> Executing :py:publish
Publishing
{'username': '...', 'password': '...'}

 >> Executing :py:publish
Publishing
{'username': '...', 'password': '...'}

Example of –help per command:

$ rkd :my:test :my:test --help
usage: :py:publish [-h] [--username USERNAME] [--password PASSWORD]

optional arguments:
  -h, --help           show this help message and exit
  --username USERNAME  Username
  --password PASSWORD  Password
