How do you evaluate a string as a clojure expression?

User> (eval (read-string "(+ 1 2)")) 3 You probably shouldn't ever need to do this. Macros and fns make this kind of thing unnecessary 99% of the time. This is quite brittle, and can be unsafe if these strings are coming from user input, and so on.

Well I want to do something radically unsafe: a REPL chatbot. – Nick Orton Dec 11 '09 at 15:43 There is a clojurebot in #clojure. – JH.

Clojure's eval works on lists, so: (eval (list + 1 2)) #=> 3.

I know about eval, but I don't think it works for me. I really want to evaluate a "String" – Nick Orton Dec 11 '09 at 2:35.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
