Abstract
|
|
========
|
|
|
|
At present, setting the ``PYTHONPATH`` environment variable is the
|
|
only method for defining additional Python module search
|
|
directories.
|
|
|
|
This PEP introduces the '-P' valued option to the python command
|
|
as an alternative to ``PYTHONPATH``.
|
|
|
|
|
|
Rationale
|
|
=========
|
|
|
|
On Unix::
|
|
|
|
python -P $SOMEVALUE
|
|
|
|
will be equivalent to::
|
|
|
|
env PYTHONPATH=$SOMEVALUE python
|
|
|
|
On Windows 2K::
|
|
|
|
python -P %SOMEVALUE%
|
|
|
|
will (almost) be equivalent to::
|
|
|
|
set __PYTHONPATH=%PYTHONPATH% && set PYTHONPATH=%SOMEVALUE%\
|
|
&& python && set PYTHONPATH=%__PYTHONPATH%
|
|
|
|
|
|
Other Information
|
|
=================
|
|
|
|
This option is equivalent to the 'java -classpath' option.
|
|
|
|
|
|
When to use this option
|
|
=======================
|
|
|
|
This option is intended to ease and make more robust the use of
|
|
Python in test or build scripts, for instance.
|
|
|
|
|
