config

Uses a JSON superset with comments, includes, and substitutions, making configuration files more readable and maintainable than plain JSON or properties files, as detailed in the HOCON.md spec.

Based on immutable Config instances, ensuring safe concurrent access and predictable behavior in multi-threaded environments without synchronization overhead.

Supports loading from files, URLs, classpath resources, and system properties with automatic merging and priority-based overriding, simplifying multi-environment deployments.

Converts values between strings, booleans, durations, and sizes (e.g., '10 seconds' or '512k'), reducing parsing boilerplate and potential errors as highlighted in the features list.
