best way to handle file extension (.txt) when constructing path?

[scarf005]

val path = "toolkit"
scala> os.pwd / (path + ".scala")
val res1: os.Path = /run/media/home/scarf/repo/etc/kata/toolkit.scala

is this the intended way to add file extension to path?

Yes.

[lihaoyi]

os.pwd / s"$path.scala" works too
