Ah, gotcha. Thanks for the explanation Tomas. I'll make that change. ~Jimmy Sent from my phone

It is only set by ScriptSource.ExecuteProgram(). The reason is that each call to the former methods creates a new top-level binding and therefore we don’t know which one should be the one that is stored in TOPLEVEL_BINDING. The latter is meant to be used to execute the main top-level code (i.e. the “program”) and it sets the TOPLEVEL_BINDING up. It also handles SystemExit exception so that “exit” works according to Ruby’s semantics. IronRack should probably use ExecuteProgram to execute the main request processing script.

I found that one thing expected by Camping was the global constant TOPLEVEL_BINDING. Apparently the constant was not defined in IR. A Google search found it in: ironruby/Merlin/Main/Languages/Ruby/Libs/hacks.rb And when I explicitly required it, the constant appeared and Camping worked immediately on IronRack. Could someone explain what the constant is for and why it is located in hacks.rb? Is it ok to I be using hacks.rb? Philippe PS - I am pretty excited to run Camping now! I just had to make a couple changes on top of IronRack to make it work. Philippe Monnet wrote: I have been leveraging IronRack to try to get a sample Camping application up and running. I seem to be able to require the camping library fine but then as try to hit the famous "Camping.goes :Demo" line, IronRuby return an error stating that the constant #<Class:Camping> is not initialized. So I tried to do the same test using the IR command line executable, but ran into the same issue (note that the same test works fine in IRB). What is strange is that the camping framework is loaded and if I query the constants in the Camping module I get back what I would expect. Is this a module loading issue? How can I troubleshoot this further? Here is the IR's transcript: --------------- >ir IronRuby 0.9.0.0 on .NET 2.0.50727.3082 Copyright (c) Microsoft Corporation.
