forum > How can I know the Haxe version?

• xr.zeng Aug 19 at 03:35

  code like below:

  #if haxe_208
  trace("haxe 2.08");
  #else
  trace("not haxe 2.08");
  #end

  How can I check if the version is greater than 2.08?
  like this:
  #if version >= haxe_208
  trace("greater than or equal haxe 2.08");
  #else
  trace("less than haxe 2.08");
  #end;

  Thanks!

  Let me start by saying, I could be wrong

  According to the manual - http://haxe.org/ref/conditionals
  

  #if haxe_210
      trace(" haxe version == 2.10");
  #else
      trace(" haxe version != 2.10");
  #end

  so

  #if haxe_208
      trace(" haxe version == 2.08");
  #else
      trace(" haxe version != 2.08");
  #end

  BUT - from something I read somewhere, and actually trying it, it's really

  #if haxe_208
      trace(" haxe version >= 2.08");
  #else
      trace(" haxe version < 2.08");
  #end

  Actually, it is in away3dlite.core.utils
  Cast.hx
  #if haxe_206
  import flash.errors.Error;
  #else
  import flash.Error;
  #end

  and my haxe version is 2.08. Then it can't be compiled.

  ../away3d/trunk/haxe/Away3DLite/src/away3dlite/core/utils/Cast.hx:14: characters 0-19 : Class not found : flash.Error

  The behaviour I described with

  #if haxe_208

  seems to have changed since 2.09

  From a quick look at haxe source code, in 2.08 and earlier

  #if haxe_xyy

  would only be true when the version is exactly x.yy

  Just upgrade to current haxe - then you'll have no such compatibility issues
