kumade 0.2.0

A make-like build utility for Python.

kumade

A make-like build utility for Python.

Features:

• You can define tasks, such as executing commands, creating files, or invoking functions, in Kumadefile.py, with standard Python code.
• You can run tasks from shell with kumade command.
• Any task can have its dependencies and kumade considers the dependency graph to determin the task execution order.
• Kumade decides whether or not to perform a file creation task with considering the file existence and whether its timestamp is older than its dependencies.

Kumade means rake in Japanese, and it is regarded as a lucky charm because it collects happiness.

Getting started

Install

To install kumade, use pip:

pip install kumade

Write Kumadefile.py

To define tasks, write Kumadefile.py.

For example,

import kumade as ku

from pathlib import Path
import subprocess

ku.set_default("greet")

help_file = Path("help.txt")

@ku.task("greet")
@ku.depend(help_file)
def greeting() -> None:
    print("Hi, this is Kumade.")
    print(f"See {help_file}.")

@ku.file(help_file)
def create_help_file() -> None:
    with help_file.open("w") as outfile:
        subprocess.run(["kumade", "-h"], stdout=outfile)

This example defines two tasks and sets default task.

The task "greet" is defined by the decorator @ku.task("greet") and it will output a greeting when executed. This task depends on the file "help.txt" and kumade will execute the file creation task if it does not exist.

The file creation task for "help.txt" is defined by the decorator @ku.file(help_file) and it will create the file by capturing the standard output of command execution.

You can see more examples of task definition in the file Kumadefile.py in the kumade repository.

Run

To run tasks from shell, use kumade command:

kumade

kumade command loads task definitions from Kumadefile.py and runs the specified tasks (or the default task if no task is specified).

Run kumade --help to see available options.
