MagicCFG v1.3: Smarter Configuration, Less Boilerplate
Before:
April 18, 2026
# schema.yaml database: host: string port: number(min=1024, max=65535) If a value is missing or invalid, you’ll get a clear error before your app starts — no more runtime surprises. We rewrote the internal merge engine in Rust (behind a Python binding) while keeping the API identical. Large configs with deep inheritance now load in half the time. For microservices and serverless environments, this means faster cold starts. 4. Environment Variable Interpolation You can now reference environment variables directly inside any config file:
db_host = config["database"]["production"]["host"] After (v1.3):
db_host = config.dot("database.production.host") Better yet, dot() supports default fallbacks and will never throw an attribute error on missing paths. MagicCFG v1.3 introduces optional JSON Schema support. Define your expected config shape once, and let MagicCFG validate types, required fields, and patterns on load.
api: key: ${API_KEY} url: "https://${ENV}.example.com" MagicCFG resolves these at load time, with clear warnings for missing variables. Python (PyPI):
go get github.com/magiccfg/magiccfg@v1.3
