Scala Native name demangler

Status: sort of works.

Why?

Scala Native mangles names in the binaries according to a particular scheme:

https://scala-native.readthedocs.io/en/latest/contrib/mangling.html

This project parses the mangled name back into a more readable format. It is distributed as both a runnable application, and an embeddable library.

Application

Launch the JVM version using coursier:

$ cs launch com.indoorvivants::sn-demangler:latest.release -- -s '_SM36scala.scalanative.runtime.BoxedUnit$G8instance' '_SM34scala.scalanative.runtime.package$D16throwNullPointernEO'

// scala.scalanative.runtime.BoxedUnit$.<generated> instance
// scala.scalanative.runtime.package$.throwNullPointer(): Nothing

• -s id1 id2 id3 ... accepts any number of identifiers
• -f <filename> - processes a file, assuming a single identifier per line
• -i - accepts input from stdin
