Configurable is the only config library supporting javadocs for adding comments. for example:
Java:
/// Some Comment™
@Configurable
public static int someInt = 42;
Toml:
# Some Comment™
someInt = 42
Json:
{
// Some Comment™
someInt: 42
}
Despite Configurable being the only one supporting this awesome feature, numerous other config libraries have the technology to do this, off the top of my head owolib and malilib api, since they both use annotation processors, but I know there are more. Bonus fact: Configurable is the only config library not needing your config values to be bound to one or more specific classes. You can just put them anywhere in your codebase, and it'll work!
