I'm using the ConfigFactory class to load the config of my application, but i want to know how can I load a line from other file and add it to the Config object.
The file only contains 1 line with the value I want, and i want to add that value with to the config with a new key or better to a existing one, so i can have a default value.
Is it possible to add a custom key/value after the config is loaded?, like:
You can do this by using
// Assuming this is your first config file val default = ConfigFactory.load("application.conf") // Now we add the second one val updated = default.withFallback(ConfigFactory.load("foo.conf"))
Or, assuming you have read your
line elsewhere as a value, use the same method but parse the config from the string directly using
val default = ConfigFactory.load("application.conf") val updated = default.withFallback(ConfigFactory.parseString(s"key = $value"))
