Environment Generator¶

EnvGenerator produces a validated .env file from your workflow and agent configuration.

meshflow env-gen workflow.yaml --out .env.production

Python API¶

from meshflow import EnvGenerator, ValidationIssue

gen = EnvGenerator()
env_str, issues = gen.generate_from_yaml("workflow.yaml")

for issue in issues:
    v: ValidationIssue = issue
    print(f"[{v.severity}] {v.key}: {v.message}")

# Write to file
with open(".env.production", "w") as f:
    f.write(env_str)
