(Resending again as plain-text (hopefully) to ensure it makes it through the google groups gateway.) My company is working on a piece of software right now that is using .NET. One of the features is a scripting console similar to IRB: the user may type in one-off commands and see the effect in the application. I want the scripting language to be Ruby. Right now, it’s IronPython. I’ve been told that the reason is that with using Ruby under this scenario, a new Assembly is created for each command that the user enters. This is a Bad Thing, as it’s been described to me, for performance and memory. IronPython doesn’t suffer this problem. (I was also told that there is some nasty way to get around the problem that involves tying objects together and marshalling data back and forth. Or something. Hopefully I got the description right; I’m a Ruby scripter, not a .NET programmer.) 1. Does this sound correct to people who know Ruby/.NET or RubyCLR? 2. If it’s not correct, could you elaborate on how one might achieve the functionality I describe above? 3. If it is correct, how can it be fixed? If Python managed a solution, I assume Ruby could as well. I’d really like our software to use Ruby, and I could probably convince the engineers to use it if we could overcome this hurdle. More Ruby everywhere is better for the world. 😉 ---

Don’t get me wrong, it does some things well, but last I looked it still had object-identity issues and that’s a major problem for writing anything reliable. It’s fun for short-lived scripts with low object counts though. ---

Can you provide some examples of object-identity issues? Or perhaps an URL ? I am interested in using RubyCLR in production code. thanks, devdev ---
