Embracing Common Lisp in the Modern World

This page summarizes the projects mentioned and recommended in the original post on news.ycombinator.com

Our great sponsors
  • WorkOS - The modern identity platform for B2B SaaS
  • InfluxDB - Power Real-Time Data Analytics at Scale
  • SaaSHub - Software Alternatives and Reviews
  • coalton

    Coalton is an efficient, statically typed functional programming language that supercharges Common Lisp.

  • Common Lisp has bad marketing (even OCaml has Twitch streamers and "influencers" now), and bad support for general editors, both of which make it a non-starter for most curious people who have an afternoon to try something. But behind all that is magnificent activity for those who got over the initial potential energy barrier. Just to give some examples:

    1. SBCL, the most popular open source implementation of Lisp, is seeing potentially two new garbage collectors. One of them is a parallel collector written by a university student (!!) which blows my mind.

    2. SBCL has better and better support for deploying Liwp as a C-compatible shared library, using SBCL-LIBRARIAN. It makes it play nicer with other applications in C and Python.

    3. Coalton is another exciting development that allows a Haskell type system and "Lisp-1" functional programming in Common Lisp. That means type classes (or traits), something Lisp hasn't really had a proper notion of, and full type inference. Persistent sequences based off of RRB-trees were recently merged, and interestingly, they're implemented purely in Coalton [1]. That means Clojure-like seqs.

    It's interesting to see users of Lisp generating the above ideas and libraries, not a special in-group of committees, "official" developers, etc.

  • clog

    CLOG - The Common Lisp Omnificent GUI

  • WorkOS

    The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  • slime-breakpoints

    SLIME extension for setting up breakpoints

  • Do you say so for Emacs and Slime's debugger too? It's certainly weird at first, but powerful and integrated. Although it isn't graphical like LispWorks' (and probably Allegro's), so I agree it could be even better. (for readers: Slime's debugger is not a separate CLI tool running in a window)

    (ps: see slime-breakpoints for a nice graphical addition: https://github.com/mmontone/slime-breakpoints)

  • dots

    personal dotfiles / maybe folders later (by Jach)

  • I mostly agree, though I find Allegro and LispWorks severely lacking in areas too. The companies themselves don't seem to care much about their IDEs. Certainly not in the way JetBrains cares about IntelliJ.

    Tucked away in the McCLIM project is Clouseau, which you can quickload and use as a normal user: https://codeberg.org/McCLIM/McCLIM/src/branch/master/Apps/Cl... One small cool thing it does is if you inspect a complex number it will also draw a little x-y vector. (Though trying it out again just now it's overlapping with the text... maybe I should file a bug, but I've only now just learned they moved off github, and I'm not going to make a codeberg account. Friction wins this round.) It does take a while to first compile and load all the dependencies, especially 3bz, another weakness of at least our free Lisps; AFAIK there's still no equivalent of make -j for compiling systems.

    I'm a happy vim user (though there is some jank with slimv, admittedly, but it's mostly prevalent around multiple thread situations) and setup the command ,ci to call my own clouseau-inspect function; it just inspects a symbol with clouseau instead of slimv's inspector. Also have a janky watch/unwatch pair of functions that just refreshes the inspector every second. (https://github.com/Jach/dots/blob/master/.sbclrc#L113 if curious, some other junk in .swank.lisp and .vimrc too, and there's https://github.com/dense-analysis/ale/issues/4061 to call sblint on your project...)

    But better forms of these sorts of graphical tools are what I hope to one day see more of and are how the free Lisps can close the gap in this area with the commercial Lisps. I believe there's not much Allegro can do that poking around SBCL can't do, but for many things it's just nicer to have a GUI. Want to explore all the symbols and values in a package? Easy enough to script that, but not as nice as just having a table of symbols, and even nicer if you can set watches on some of them. None of the tools need to be tightly integrated with a single IDE either, because all the stuff necessary to debug Lisp is in the running Lisp itself. It's just that the GUI situation continues to suck.

    LSP has gotten more popular with other languages and editors, sometimes I wonder if the acronym was made as an inside joke because it's basically how Lisp + Slime/Swank have worked...

  • ale

    Check syntax in Vim/Neovim asynchronously and fix files, with Language Server Protocol (LSP) support

  • vim-grepper

    :space_invader: Helps you win at grep.

  • I'm curious, what specifically works better about their IDE for you in the case of many files? Do they now have good global refactoring tools, like you can change a class name in library A and have it automatically be updated in library B and application C that depend on and use it? And without the actual files for such being open? (I'm reduced to what's essentially mass search-replace with https://github.com/mhinz/vim-grepper/ but it does the job and importantly helps update files I might not have open buffers for. Still a step down from what's available in JavaLand. I remember someone was working on a library to build some modern refactoring tools for Lisp but I don't know how far that's gotten.)
