PureConfig v0.9.0 Release Notes

Release Date: 2018-01-08 // over 6 years ago

    • 🆕 New features

      • A new ConfigCursor now provides idiomatic, safe methods to navigate through a config. It also holds context for building failures with a more accurate location and path in the config;
      • ConfigReaderFailure was revamped to facilitate the propagation of context on failures. There is now a separation between higher-level ConfigReaderFailures and concrete, location-agnostic FailureReasons.

    • 💥 Breaking changes

      • ConfigReader, as well as many related methods and classes, now reads configs from ConfigCursor instances instead of from direct ConfigValues. Code can be migrated simply by accessing the value field of ConfigCursor whenever a ConfigValue is needed. However, rewriting the code to use the new ConfigCursor methods is heavily recommended as it provides safer config handling and much better error handling;
      • Code for handling and raising failures may not work due to the revamp of the failure model. Inside ConfigReader instances users should now use the failed method of the new ConfigCursor instead of manually creating instances of ConfigReaderFailures;
      • The CannotConvertNull failure was removed, being superseeded by KeyNotFound;
      • Methods deprecated in previous versions were removed.

    • 🐛 Bug fixes

      • Fixed a bug where some or all Derivation cases outside the pureconfig package were not showing the full error description.
