How to use multiples routes for same resources

I have many URI for same resource in Ktor. To avoid to repeat too many lines, I found this solution:

routing {

    get("/", home())
    get("/index", home())
    get("/home", home())

    ...
    
}

private fun home(): suspend PipelineContext<Unit, ApplicationCall>.(Unit) -> Unit =
    {
        val parameters = ...
        call.respond(ThymeleafContent("/index.html", parameters))
    }

Is there more elegant solution like this:

routing {

    get("/", "/index", "/home") {
        val parameters = ...
        call.respond(ThymeleafContent("/index.html", parameters))
    }
    
    ...
    
}

The only way I know of compressing that would be to create a global variable containing the home-paths and then forEach it.

val homePaths = arrayOf("/path1", "/path2", ...)

...

routing {
    homePaths.forEach { path -> get(path, home()) }
}

A cool feature would be to be able to specify a regular expression as the input of the routing method.

And something that you can cook for yourself is a KTX that does such thing.

fun Routing.get(varargs routes: String, call: suspend PipelineContext<Unit, ApplicationCall>.(Unit)) {
    for (route in routes) {
        get(route, call)
    }
}

And finally call it like:

routing {
    get("/path1", "/path2") { /* your handling method */}
}
