Read environment variables defined in a shell script into Python.

cmdvars

Read environment variables defined in a shell script into Python.

This library uses the shell to get variable values, and handles multiline variables.

Usage

Given a shell file: myvars.env:

#!/bin/bash
export VAR1=1
export VAR2="This
is
a
multiline value"
export VAR3=3
NOT_EXPORTED=4

get_vars

>>> import shellvars
>>> shellvars.get_vars('myvars.env')
{'VAR1': '1', 'VAR2': 'This\nis\na\nmultiline value', 'VAR3': '3' }

list_vars

Lists the variable names in the script.

>>> import shellvars
>>> shellvars.list_vars('myvars.env')
['VAR1', 'VAR2', 'VAR3']

This is equivalent to, but faster than

>>> shellvars.get_vars('myvars.env').keys()
