PkgScript 0.6.1

Python module that allows a packaged module to run properly as a script

PkgScript (version 0.6)

Python module that allows a packaged module to run properly as a script.

It imports the enclosing package(s) into the script, allowing the script to import other modules from the same package family (using explicit relative or absolute import statements).

!!!
import_parent_packages() must be called before any package-sibling imports
!!!

Examples:

Milo.mod_script.py

import pkgscript
# Only call function if module is being run as a script
if (__name__ == "__main__") and (__package__ is None):
    pkgscript.import_parent_packages("Milo", globals())
from Milo.version import __version__
from .version import __version__    # same as previous line

top_pkg.sub_pkg.sub_sub_pkg.mod_script.py

import pkgscript
# Only call function if module is being run as a script
if (__name__ == "__main__") and (__package__ is None):
    pkgscript.import_parent_packages(
        "top_pkg.sub_pkg.sub_sub_pkg", globals())
# Import top_pkg.sub_pkg.other_module
from top_pkg.sub_pkg import other_module
from .. import other_module    # same as previous line
from ...sub_pkg import other_module    # same as previous line

ALS.Milo.mod_script.py

import pkgscript
# Only call function if module is being run as a script
if (__name__ == "__main__") and (__package__ is None):
    pkgscript.import_parent_packages("als.milo", globals())
from als.milo import __version__, __date__
from . import __version__, __date__    # same as previous line
