envdir 0.1

Why?

Because it’s small enough that it shouldn’t be tied to a bigger software distribution like daemontools. Also, this Python port can easily be used on Windows, not only UNIX systems.

Installation

pip install envdir

or:

easy_install envdir

Usage

Quoting the envdir documentation:

envdir runs another program with environment modified according to files in a specified directory. Interface:

envdir d child

d is a single argument. child consists of one or more arguments.

envdir sets various environment variables as specified by files in the directory named d. It then runs child.

If d contains a file named s whose first line is t, envdir removes an environment variable named s if one exists, and then adds an environment variable named s with value t. The name s must not contain =. Spaces and tabs at the end of t are removed. Nulls in t are changed to newlines in the environment variable.

If the file s is completely empty (0 bytes long), envdir removes an environment variable named s if one exists, without adding a new variable.

envdir exits 111 if it has trouble reading d, if it runs out of memory for environment variables, or if it cannot run child. Otherwise its exit code is the same as that of child.

Alternatively you can also use the python -m envdir form to call envdir.

To use envdir in a Python file (e.g. Django’s manage.py) you can use:

import envdir
envdir.read()

envdir will try to find an envdir directory next to the file you modified.

It’s also possible to explicitly pass the path to the envdir:

import os
import envdir

envdir.read('/etc/mysite/envdir')
