Hej !

I want to call a function in macro initialization context (called from the .hxml file).  
This function is in a file that has some macro function and some not, separated by `#if macro` directives.

```haxe
public static function addDirectives(){
	if( haxe.macro.Compiler.getDefine( "a_define" ) != null ){
		haxe.macro.Compiler.define( "my_define" );
	}
}

```

If I put this function in `macro` section, compiler throws me `macro-in-macro` but if I put it in `!macro` compilers can’t find this function…

I think I could work if it was in another file but I don’t want to add a file just for one little macro initialization function.

is there any compiler directives that maybe kind of “separate” the macro contexts ?  
Something like `#if macro_init` ?

What are my possibilities please ?

Thanks for your answers !

If I define something using `haxe.macro.Compiler.define( "my_define" )` , it won’t be useable with `#my_define` right ?  
It will only be available by `haxe.macro.Context.defined()` or `haxe.macro.Compiler.getDefine()` right ?
