Hi
Is it possible to declare a list of Json objects in the config file and read it with the config.property?

we have something like this:

key : [
{
  aKey: aValue
},
{
  bKey: bValue
}
]
....

IJ suggesting me one of those but I am not sure which one to use

[Aleksei Tirman [JB]]

val objects = environment.config.configList("key")
println(objects[0].property("aKey").getString())
println(objects[1].property("bKey").getString())

@Aleksei Tirman [JB] thanks worked

Another related question: is there a way to get the key value (in my example the aKey and the bKey ) ?

[Aleksei Tirman [JB]]

Do you mean to get keys of all objects in an array?

[Jgafner]

I mean to be able to old the objects as a map [“aKey”:“aValue”,….]

[Aleksei Tirman [JB]]

You can iterate over a list of objects and then get their keys using keys() method but this functionality will be available only in Ktor 2.0.0.

[Aleksei Tirman [JB]]

As a workaround, you use the solution described here.

thanks but I was trying to avoid the use of ConfigurationFactory since I am passing the ktor config as a parameter for tests purpose , I will hack it with hardcoded value for now and will wait for Ktor 2.0.0

Thanks a lot

@Jgafner
You can use Config4k to convert application.conf to the kotlin data class and pass it as parameter

Here is the example in my side project
