Scripting sclang via external process

You might want to check out how supercollider.js does it:

If I remember correctly, you need to get your parenthesized, multi-line code, append the escape char that means “execute”, and send it to sclang:

write(chunk: string, noEcho: boolean): void {
  if (!noEcho) {
    this.log.stdin(chunk);
  }
  this.log.dbug(chunk);
  if (this.process && this.process.stdin) {
    this.process.stdin.write(chunk, "UTF-8");
    // Send the escape character which is interpreted by sclang as:
    // "evaluate the currently accumulated command line as SC code"
    this.process.stdin.write("\x0c", "UTF-8", error => error && this.log.err(error));
  }
}

/**

I have never used Elixir, so I can’t write any code example, sorry
