From: Tristan Shelton Date: 2009-09-06T20:47:47+09:00 Subject: Opinion: Scripting in a Ruby program Hello all, I'm working on a small program -- and learning to love Ruby all over again -- but I've come across a small dilemma: What if you want to make a Ruby program that can be extended without modifying the original code? That is, a Ruby script that can itself be scripted. What I'm thinking of is something that gives users the ability to do basic math, access explicitly allowed methods and properties and maybe even allow user defined variables available only to that script, while disallowing any other use of the parent Ruby script. Something that is to Ruby what Ruby, Perl and Python are to C/C++. I considered loading chunks of Ruby script and using eval() in a safe context, and also considered creating a very simple interpreted scripting language in Ruby, but before I proceed with either option I would like to pose this question to fellow Ruby enthusiasts: How would you handle making a scriptable/extensible Ruby program like this? -- Posted via http://www.ruby-forum.com/.
