Haxe Forum > how to convert a expr to string

• joydance Jul 30 at 05:38

  Hello guys, I am recently insterested of haxe macro, and think it's very useful.
  And now I have a question: it's able to convert a expression to a string in a macro definition, because I want write something like this:

  MyMacro.println(obj.a, obj.b, obj.c) //and it will output this :
  Lib.println("obj.a:" + obj.a)
  Lib.println("obj.b:" + obj.b)

  I just not understand how to convert a expr like obj.a to a string as "obj.a", is there any way to do this?
  Thanks a lot.:)

  I don't know about converting

  obj.a

  
  into the string "obj.a", but you could use

  Reflect.fields(obj)

  
  to get all the fields and then use Lambda map

  Using Lambda;
  var debug = Reflect.fields(obj).map(function(field:String) : String
  {
    return "obj." + field + ": " + Reflect.field(obj,field);
  }).array().join("\n");

  
  to get a nice string for all the field of an object without having to specify them one by one.

  Hope this helps
