Cuttlefish Easing the Pain of Configuration
summary
Cuttlefish is a schema-driven config tool that turns a simple human file (react.conf) into Erlang app.config and vm.args, validates types (durations, sizes, enums), collects multiple errors and gives Levenshtein suggestions, and fails fast at node start if values are invalid. It ships a rebar plugin, an escript CLI, generates packaged defaults, supports commented/hidden advanced knobs, lets you unit-test schemas, and migrates existing app.config/vm.args; the project is on GitHub and is used successfully in production deployments.
