    I wrote a technical history book on Lisp▲252

    The book page links to a blog post that explains how I got about it (and has a link to sample content), but the TL&DR is that I could not find a lot of books that were on "our" history _and_ were larded with technical details. So I set about writing one, and some five years later I'm happy to share the result. I think it's one of the few "computer history" books that has tons of code, but correct me if I'm wrong (I wrote this both to tell a story and to learn :-)).

    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 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!
