• build: fix JitPack signing failure

Major Features and Improvements

• feature: support listener for watched file/URL
• feature: support listener for watched Git file
• feature: support beforeSet/afterSet for config
• feature: support beforeSet/afterSet for item
• feature: support beforeLoad/afterLoad for config

Breaking Changes

• remove action parameter for Git source

Deprecated

• build: remove bintray support

• update dependencies

Major Features and Improvements

• feature: support to load keys as little camel case by default
• feature: support empty YAML/JSON files
• feature: support to interpolate Byte/Short/Int/Long/BigInteger/Char
• feature: support to merge sources with different features
• feature: support to aggregate sources from different layers
• fix: support for non-map based StdSerializer
• fix: discover all official providers automatically

Breaking Changes

• All keys in sources are loaded as little camel case by default, e.g., tcpPort and tcp_port in the source are treated as the same key. You can use config.disable(Feature.LOAD_KEYS_AS_LITTLE_CAMEL_CASE) to disable this change.

Deprecated

• fromXXX APIs on providers are removed use the new shorter APIs instead. E.g., you can use file instead of fromFile.

• feature: support flatten env source (#41)

  If you have the following environment variables:

  DATABASE=foo.example.com
  DATABASE_USER=john
  DATABASE_PASS=doe
  

  You can load them without any name conversion by using config.from.env(nested=false):

  object Root : ConfigSpec("") {
      val DATABASE by required<String>()
      val DATABASE_USER by required<String>()
      val DATABASE_PASS by required<String>()
  }
  
  Config {
      addSpec(Root)
  }.from.env(nested=false)
  

• fix: support numeric keys in source

  Now you can use numeric keys in source (use YAML as example):

  tree:
    1:
      myVal: true
  

A serious configuration error in Gradle has been fixed in this version. This bug will cause compilation error when using konf without simultaneously declaring dependency to konf-core since v0.15. Please upgrade to this version if you are using v0.15~v0.20.0.

• feature: support to cast config to value with config.toValue<T>()
• fix: watchFile throws exception when using relative path
• fix: parsing of environment variables is stricter now

Major Features and Improvements

• feature: support default providers API
• feature: support substituted source
• feature: all sources are substituted before loaded into config by default

Breaking Changes

• Since all sources are substituted before loaded into config by default, all path variables will be substituted now. You can use config.disable(Feature.SUBSTITUTE_SOURCE_BEFORE_LOADED) to disable this change.

Deprecated

• fromXXX APIs on providers are deprecated now, use the new shorter APIs instead. E.g., you can use file instead of fromFile.

• feature: migrate to tree-based config
