• Rake style parameter passing to tasks.

• Running tasks by typing the first few characters.

• Breaking up script into modules.

Installation

You can install microbuild from the Python Package Index (PyPI) or from source.

Using pip:

$ pip install microbuild

Using easy_install:

$ easy_install microbuild

Example

The build script is written in pure Python and microbuild takes care of managing any dependancies between tasks and generating a command line interface.

Tasks are just regular Python functions marked with the @task() decorator. Dependancies are specified with @task() too. Tasks can be ignored with the @ignore decorator.

After defining all tasks build(sys.modules[__name__],sys.argv[1:]) is called to run the build.

# example.py
import sys
from microbuild.microbuild import task,ignore,build

@task()
def clean():
    """Clean build directory."""
    print "Cleaning build directory..."

@task(clean)
def html():
    """Generate HTML."""
    print "Generating HTML..."

@ignore
@task(clean)
def images():
    """Prepare images."""
    print "Preparing images..."

@task(html,images)
def android():
    """Package Android app."""
    print "Packaging android app..."

if __name__ == "__main__":
    build(sys.modules[__name__],sys.argv[1:])

The command line interface and help is automatically generated. Task descriptions are extracted from function docstrings.

$ ./example.py -h
usage: example.py [-h] task

positional arguments:
  task        perform specified task and all it's dependancies

optional arguments:
  -h, --help  show this help message and exit

tasks:
  android     Package Android app.
  clean       Clean build directory.
  html        Generate HTML.
  images      Prepare images.

Dependancies between tasks are taken care of too.

$ ./example.py android
[ example.py - Starting task "clean" ]
Cleaning build directory...
[ example.py - Completed task "clean" ]
[ example.py - Starting task "html" ]
Generating HTML...
[ example.py - Completed task "html" ]
[ example.py - Ignoring task "images" ]
[ example.py - Starting task "android" ]
Packaging android app...
[ example.py - Completed task "android" ]
