This prevents the most obvious issues, as it means any string read in from the Rouge code itself is immutable. The wider question of strings in Rouge code in general is going to be a concern, and something I'll probably have to mull over more shortly. :) There are some options (which I don't quite like), such as freezing strings on entry to Rouge code and duping them on exit. - Arlen -- You received this message because you are subscribed to the Google Groups Clojure group.

This prevents the most obvious issues, as it means any string read in from the Rouge code itself is immutable. A problem with `freeze` in Ruby is that it both prevents changing the contents of an object and also the methods attached to it. I find it useful sometimes to take an immutable object and create a new object with a different interpretation: hash.become(TimesliceShaped) What that does is produce an object with some new singleton methods. That lets me do something like Clojure's `-` or the common Ruby boxcar notation: timeslice.transform.update It makes the code more readable. This is also vaguely analogous to multimethods. The point is that we want the functions applicable to an object to be mutable but the contents of the object to be immutable. - Brian Marick, Artisanal Labrador Contract programming in Ruby and Clojure Occasional consulting on Agile Writing /Functional Programming for the Object-Oriented Programmer/: https://leanpub.com/fp-oo -- You received this message because you are subscribed to the Google Groups Clojure group.

As for mutability in Rouge, I had another thought—freezing (or possibly duping then freezing) Ruby String objects when returned by the core evaluator would probably do the trick comprehensively; it would incur a performance penalty, but it would be at least starting on the right foot. -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: Rouge: Ruby + Clojure
Hi Armando, Thanks for giving it a go! On second thought, I've decided against 1.8 support. 1.8 was released initially in 2003, and is now considered deprecated. I gave it a solid go to see if the code I wrote was mostly-compatible with 1.8, but it started to turn into something of a dog's breakfast.

Re: Rouge: Ruby + Clojure
I didn't realize 1.8 was such and old version; will get a recent build and give it another try. I'm interested in scripting, so the basic pieces are already there. With a short startup time this will be looking really useful. On Friday, October 12, 2012 6:05:39 PM UTC-7, Arlen Christian Mart Cuss wrote: Hi Armando, Thanks for giving it a go!
