New Project: cl-tar

posted on 23 Sep 2021 15:10:00 UTC

I have just published the first release of a new project: cl-tar. This was supposed to be my summer side-project, but it ran long as they often do :).

The goal of this project is to provide a Common Lisp interface to tar archives. It has its foundations in Nathan Froyd's archive library, but has been significantly extended and improved.

CLPM 0.4.0 released

posted on 2021-09-14 09:00:00

I have tagged CLPM 0.4.0 and posted the build artifacts at This release brings quite the laundry list of bug fixes and enhancements, including the much awaited Mac M1 support. The full changelog summary is below the break.

Additionally, the burgeoning CLPM community now has more spaces to interact. If you're interested in learning about or getting help on CLPM, I encourage you to join #clpm on We have a Matrix room as well (, but the Libera room is currently more active and preferred.

If you are already using CLPM, I encourage you to subscribe to the clpm-announce mail list. This is a low traffic list where new releases will be announced.

Toward a New CL Project Index

posted on 2021-09-05 22:00:00

Quicklisp has had a profound impact on the CL community. It's transformed the way CL devs share libraries, made it easier and encouraged devs to re-use existing code instead of implementing everything in house, and is widely used. While Quicklisp took the CL community a huge step forward, I nevertheless think we can and should do better.

To that end, I've been working on two interlinked projects, CLPM and the Common Lisp Project Index (CLPI). I've posted about CLPM in various places before and awareness of it is already growing in the CL community. Therefore, this post will focus on CLPI and why I think it is important. My ultimate goal is to find like-minded people to collaborate with on bringing CLPI (or something similar) to reality.

CLPM 0.4.0-rc.1 Available

I have just tagged CLPM 0.4.0-rc.1 and posted the build artifacts at Assuming there are no show stoppers discovered, I plan to release v0.4.0 next weekend.

ASDF 3.3.5 Release Candidate

ASDF has been tagged. This is a release candidate for 3.3.5. As the announcement says, please give it a spin on your setup and report any regressions. Bugs can be reported to the Gitlab issue tracker (preferred) or to the asdf-devel mailing list.

New Project: adopt-subcommands

posted on 2021-04-22 11:00:00

I have just released a new project: adopt-subcommands. This project extends the excellent Adopt library with support for arbitrarily nested subcommands. See the README for more information.

I have just asked that it be included in Quicklisp, so hopefully it will be present in the next QL release.

Static Executables with SBCL v2

posted on 2021-02-24 21:50:00

It's taken me much longer than I hoped, but I finally have a second version of my patches to build static executables tested and ready to go! This set of patches vastly improves upon the first by reducing the amount of compilation needed at the cost of sacrificing a little purity. Additionally I have created a system that automates the process of building a static executable, along with other release related tasks.

Common Lisp Docker Images

As alluded to in my previous post, I've been working on a set of Docker images for Common Lisp. The latest version of that effort is now finally live! Check it out at Many thanks are also due to the Common Lisp Foundation for hosting the images on their Docker Hub org!

Static Executables with SBCL

posted on 2021-01-05 13:00:00

UPDATE: Make sure to see my follow up post to this).

Common Lisp is an amazing language with many great implementations. The image based development paradigm vastly increases developer productivity and enjoyment. However, there frequently comes a time in a program's life cycle where development pauses and a version must be delivered for use by non-developers. There are many tools available to build an executable in Common Lisp, most of which follow the theme of "construct a Lisp image in memory, then dump it to disk for later reloading". That being said, none of the existing methods fit 100% of my use cases, so this post is dedicated to documenting how I filled the gap by convincing SBCL to generate completely static executables.

Hello, World!

I've been meaning to start a technical blog for, oh, the last N years or so, but never got around to it. I finally decided that this was going to be the year for it to happen.

This blog covers asdf, blog, cl-docker-images, clpm, common-lisp, sbcl
