Excited to see an implementation of a Lisp-like language in Rust! Makes me want to spend more time working on Ruse, my own embedded Scheme for Rust (think like Lua for C). Fair warning: I have barely started Ruse. Most of my time right now is reading about different Scheme implementations. Contributions are, of course, welcome.

  What about it doesn’t look like Lisp? Just taking the example from examples/calling.rs:
  
  (define (factorial n) (cond ((< n 0) (panic "factorial got negative integer")) ((<= n 1) 1) (else (* n (factorial (- n 1))))))
  
  Superficially, this looks like Lisp to me. Maybe there are other things in the language that are decidedly un-Lisp-like, but this isn’t.

        Yui, you are getting downvoted (my guess) for:
        
        Not taking the time to read the documentation in the link posted
        
        Not adding comments of substantive value
        
        What is the usecase for this? The page is really light on any information.
        
        As written in the primary documentation for the project:
        
        Ketos is “mainly intended for extending and scripting for Rust programs.”

        If you think something is irrelevant to the site, the best response is to mark it as off-topic.

      Do you mean src/ketos/module.rs? Because that’s a Rust file that’s part of the language’s interpreter.

        I think he means examples/module.rs

        That makes more sense. In that case, the actual Ketos code in that file is:
        
        (use custom (hello)) (hello "world")
        
        The rest is just Rust code to setup and run the interpreter.

        I am not sure what module means in this case, but anyway it looks like the confusion has been sorted out as far as what the Ketos code is.
