I Made a Lisp

Hi all, powerful open-source Lisp implementations are a dime a dozen, why not try JMurmel instead? The language is inspired by Common Lisp, except it's a Lisp-1, and it is mostly a subset of CLtL-1. Jmurmel can be used standalone with or without the Repl, for "#!"-style hashbang scripts or embedded in a Java program. It features [documentation for the core language](https://jmurmel.github.io/murmel-langref.html) as well as [documentation for the default library](https://jmurmel.github.io/mlib.html), a REPL, an interpreter, a compiler, macros, backquotes,…

What it does

A standalone or embeddable JVM based interpreter/ compiler for Murmel, a single-namespace Lisp dialect inspired by Common Lisp - mayerrobert/jmurmel

    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!

    I wrote a technical history book on LispFeb 2026 · berksoft.ca · ▲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 :-)). My favorite languages are Smalltalk and Lisp, but as an Emacs user, I've been using the latter for much longer and for my…

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
