Interactive Common Lisp: An Enhanced REPL▲101
I created this because sometimes I want more than rlwrap but less than emacs. icl aims to hit that middle sweet spot. It's a terminal application with context-aware auto-complete, an interactive object inspector, auto-indentation, syntax colouring, persistent history, and much more. It uses sly to communicate with the child lisp process and aims to be compatible with any sly-supporting implementation. I hope others find it useful!
