expandvars 0.1.1

Expand system variables Unix style

expandvars

Expand system variables Unix style

Inspiration

This module is inspired by GNU bash's variable expansion features. It can be used as an alternative to Python's os.path.expandvars function.

NOTE: Although it copies most of the common behaviours, it doesn't follow it strictly. For example, it doesn't work with arrays.

Usage

from expandvars import expandvars

print(expandvars("$PATH:$HOME/bin:${SOME_UNDEFINED_PATH:-/custom/path}"))
# /bin:/sbin:/usr/bin:/usr/sbin:/home/you/bin:/custom/path

Examples

For now, refer to the test cases to see how it behaves.
