Did you put your code inside a main() function?

I want to make constant with path to directory containing executable. This line is above main():

-----------------------------
const ROOT_DIR = dirName(thisExePath());
-----------------------------

This is not allowed? :O

That would give you dmd's path, if it worked.

This is allowed:

  #! /usr/bin/env rdmd
  import std.stdio, std.path, std.file;

  @property
  string root_dir() {
      static string cache;
      static bool isInit = false;
      if (!isInit) {
          isInit = true;
          cache = dirName(thisExePath());
      }
      return cache;
  }

  void main() {
      writeln(root_dir);
  }
