Sources

A source is just a really simple interface which will be the one that will get the file from wherever needs to be fetched. The interface will just have a method that returns an InputStream which will hold the stream of bytes of the configuration.

interface ConfigSource {
    fun read(): InputStream
}

There are plenty of configuration sources already built in. Here's a list (in core):

1. URLConfigSource
2. StringConfigSource
3. StringRotationConfigSource
4. FunctionConfigSource
5. StringFunctionConfigSource
6. FileConfigSource
7. ClasspathConfigSource
