Usage

envman init        Create .env.example from .env (strips values, keeps comments)
envman sync        Add missing keys from .env.example to .env
envman validate    Check .env has all keys from .env.example
envman docs        Generate markdown docs table from .env.example

init

Creates a .env.example from your current .env — strips secret values but keeps keys and any inline # comments as documentation.

envman init

sync

Adds any keys from .env.example that are missing in .env, with empty values.

envman sync

validate

Exits with code 1 if any keys in .env.example are missing from .env. Useful in CI pipelines.

envman validate

docs

Prints a markdown table of all environment variables with descriptions.

envman docs

Why

Every project needs .env.example. Nobody keeps it in sync. This automates it — 5 seconds instead of 20 minutes of manual diffing.
