Haxe Forum > File writing with haxe

  Hello world!

  I was wondering how I could get haxe to write something in a file, I plan on targeting cpp, so I checked the libraries and found "cpp.io.File", but it's not very descriptive. Basically, I want to be able to get my program to write a file on the hard drive. Anyone have any suggestions?

  Thanks!

  Some backend aspects like this work the same in many backend targets, php, neke, c++ and eventually Java and csharp, so the tutorials for neko often cover the details, for example:
  http://haxe.org/doc/neko/fileio
  Haxe 3 is moving towards standardizing this into a new cross platform package sys so for instance look at:
  http://haxe.org/api/sys/io/file
  Let us know how you get on but I found that PHP and Neko file writing was the same just a remap so I expect c++ will also be the same, although to future proof your work try to use the sys package.

  Main.hx
  

  class Main
  {
      public static function main()
      {
          sys.io.File.saveContent("./test.txt", "hello world");
      }
  }

  
  build.hxml
  

  -main
  -cpp bin

  
  Executing Main(.exe) in the bin folder will save the text "hello world" to file test.txt inside the same folder where Main.exe is located/executed.

  OK, so that tells me how to create a file with something in it, what if I'm adding to what's already in the file?

  Please re-read my advice and then read the neko tutorials.

  Main.hx
  

  class Main
  {
      public static function main()
      {
          var f = sys.io.File.append("./test.txt");
          f.writeString("additional text");
          f.close();
      }
  }

  
  build.hxml
  

  -main Main
  -cpp bin

  This link maybe useful http://haxe.org/doc/sys/ it was written while 'sys' package was being added to haxe, so details may have changed.

  Oh, so that's what FileIO meant. OK, I think I have this now. Thanks!
