Awesome
static-config
It is a tiny library allowing to scrap some boilerplate when working with typsafehub/config. It contains less then 10 relevant lines of code, but is still quite usefull.
Install
"com.github.krever" %% "static-config" % "1.1.0"
Usage
application.conf
static-config {
intEntry = 1
stringEntry = "String"
group {
listEntry = ["val1", "val2"]
durationEntry = 6h
}
}
other-config = 2
SConfigExample.scala
import com.typesafe.config.{Config, ConfigFactory}
import staticconfig._
object SConfigExample extends SConfig {
override def config: Config = ConfigFactory.load()
object `static-config` extends LocalSConfigNode {
val intEntry = configEntry(_.getInt)
val stringEntry = configEntry(_.getString)
object group extends LocalSConfigNode {
val listEntry = configEntry(_.getStringList)
val durationEntry = configEntry(_.getDuration)
}
}
val `other-config` = configEntry(_.getInt)
}
Motivation
It can be found here.
Why not to go further?
We could take one more step and make an sbt-plugin that will generate such code directly from application.conf
.
Although it might be possible, I'm not a big fan of code generation. Some arguments against it can be found here.
Other libraries
If you're fine with compiler plugin and annotations, there is great wacai/config-annotation.
Other wrappers around Typesafe Config can be found here
