Why envstack

envstack is a lightweight CLI and Python library for composing, tracing, exporting, and reproducing environment variables using a PATH-like model called ENVPATH.

Compose

Hierarchical environment layers
PATH-like precedence
Cross-platform

Explain

Trace variable origins
Debug overrides
Deterministic resolution

Export

Bake resolved environments
Export to bash / tcsh / cmd
Reproduce exactly

ENVPATH

ENVPATH defines where environment fragments are discovered and in what order they apply — just like PATH, but for full environments.

export ENVPATH=prod/base:prod/show/foo:prod/tools/nuke14
envstack -- nuke

envstack is not:

a dependency solver
a package manager
a virtualenv replacement
a build system
magic

It is intentionally boring: explicit inputs, deterministic outputs, and tooling that tells you what it did.

Install

pip install envstack
