That shouldn't be the case. There can be at most one engine per language per ScriptRuntime.
The program seems to work on my machine.

One by the call to ScriptRuntime.GetEngine(typeof(RubyContext)); inside Robert's code and another one inside Kernel#require.

Can you grab 109 and see if this repros on your machine? I hope this isn't some strange locale thing again ... Thanks, -John -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Robert Brotherus Sent: Thursday, May 15, 2008 6:26 AM To: ironruby-core@rubyforge.org Subject: [Ironruby-core] IR SVN 107 changes behavior of 'require' (compared to SVN 103) IR 103 -> IR 107 update broke my program that relies on execution of "require '...'" strings. I don't know wether this is bug in IR 107 (or incorrect behaviour on IR 103 and earlier), so I did not file a bug report yet. I made a simplified version of my program that exposes this difference with minimal amount of code (this is a fully contained functional program): ------------------------------------------------------------------------ --- using System; using Microsoft.Scripting; using Microsoft.Scripting.Hosting; using Ruby.Runtime; class Program { static void Main(string[] args) { try { new Program().Run(); } catch (Exception ex) { Console.WriteLine(ex.ToString()); } } private void Run() { System.IO.File.WriteAllText("f.rb", @" module F def F.hello puts 'F:Hello' end end "); ExecuteStr("require 'f.rb'"); ExecuteStr("F.hello"); // IR SVN 107 fails here: "uninitialized constant Object::F" } private ScriptRuntime _scriptRuntime; private ScriptScope _sharedScope; public ScriptRuntime ScriptRuntime { get { if (_scriptRuntime == null) { _scriptRuntime = ScriptRuntime.Create(); _scriptRuntime.GlobalOptions.DebugMode = true; } return _scriptRuntime; } } public ScriptEngine Engine { get { return ScriptRuntime.GetEngine(typeof(RubyContext)); } } public ScriptScope SharedScope { get { if (_sharedScope == null) _sharedScope = Engine.CreateScope(); return _sharedScope; } } public object ExecuteStr(string code) { return Engine.CreateScriptSourceFromString(code).Execute(SharedScope); } } // class ------------------------------------------------------------------------ --- Program behaves in following way in IR SVN 103 / 107: SVN 103 F:Hello Press any key to continue . . .
