Typesafe Config (little scala wrapper)

Little scala extension to Typesafe Config

Usage

build.sbt

libraryDependencies += "com.github.andyglow" %% "typesafe-config-scala" % ${LATEST_VERSION} % Compile

Code

Import it

import com.github.andyglow.config._

And then you will be able to

Get value by specifying needed type

val v1 = config.get[String]("path")
val v2 = config.get[Int]("path")
val v3 = config.get[FiniteDuration]("path")

Get rid of if hasPath this else that by leveraging notion of options

// optional value
val val1: Option[String] = config.get[Option[String]]("path")
val val2: String         = config.getOrElse[String]("path", "default")

Have more flexible api for working with multi-values

val list1     = config.get[List[String]]("path")
val set2      = config.get[Set[Int]]("path")
val iterator3 = config.get[Iterator[ConfigMemorySize]]("path")

Supported types

• String
• Int
• Boolean
• Double
• Long
• Bytes (file size, etc...)
• Duration (java.time)
• Duration (scala)
• FiniteDuration
• ConfigList
• Config
• ConfigObject
• ConfigMemorySize
• Date (java.util)
• Date (java.sql)
• Time (java.sql)
• Timestamp (java.sql)
• LocalDate (java.time)
• LocalTime (java.time)
• LocalDateTime (java.time)
• OffsetDateTime (java.time)
• ZonedDateTime (java.time)
• DayOfWeek (java.time)
• Month (java.time)
• Year (java.time)
• Option[T] where T is one of the supported types
• scala collections. Seq[T], etc. Any sort of collection types which has corresponding CanBuildFrom

Extending

Also this can be extended by providing implementations for FromConf and/or ConfType (used for collections and might be implicitly reused for FromConf) For example take a look at com.github.andyglow.config.ConfType#juDateT implementation and spec at com.github.andyglow.config.JavaUtilDateExtSpec
