Subject: Re: local variables, eval, and parsing

Maybe something like this is what you're after?

config = "foo = 42"
source = "def config_vars; #{config}; binding; end; config_vars"
kv = eval("local_variables.inject({}) {|h,v| h[v] = eval(v); h}", eval(source))
p kv
# >> {"foo"=>42}

You might want to use a random string for the method name to avoid
name collisions or use an anonymous module but the basics are here.

Sean
