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.

Available as a native CLI, as a Webapp, and as a normal library published for JVM, JS, and Native.

• Download the native sn-demangler binary for your platform from Github Releases
• Use the Web version
• Launch the JVM version directly from Coursier:

  cs launch com.indoorvivants::sn-demangler:latest.release -- <args>
  

Demangler will attempt to find all SN identifiers, demangle them, and display the symbols inline with the rest of the text.

Let's say you have text like this:

hello _SM36scala.scalanative.runtime.BoxedUnit$G8instance world

The demangled symbols will be highlighted in the console (disable that with --plain or set NO_COLOR=true env variable).

1. Demangle a single string:

   $ sn-demangler 'hello _SM36scala.scalanative.runtime.BoxedUnit$G8instance world'
   hello scala.scalanative.runtime.BoxedUnit$.<generated> instance world
   

2. Demangle a file:

   $ cat myfile
   hello scala.scalanative.runtime.BoxedUnit$.<generated> instance world
   
   $ sn-demangler -f myfile
   hello scala.scalanative.runtime.BoxedUnit$.<generated> instance world
   

3. Demangle from STDIN:

   $ cat myfile
   hello scala.scalanative.runtime.BoxedUnit$.<generated> instance world
   
   $ cat myfile | sn-demangler -f -
   hello scala.scalanative.runtime.BoxedUnit$.<generated> instance world
