I write small libraries. If a project implements something that may potentially be useful somewhere else, I’ll factor it out.

I’ve written a lot of Common Lisp libraries. Other than libraries, I mostly write compilers or small utilities.

Austral

My current main project is the Austral programming language: a systems programming language with a linear type system. The language is designed to be simple to understand and implement.

The key features are: memory safety, data race freedom, and capability-based security.

Common Lisp Website

I built a website to promote Common Lisp, including a gallery of Lisp success stories, a wiki, and a tutorial.

Crane

Crane is an ORM for Common Lisp. It uses CLOS’s amazing MetaObject Protocol to map Common Lisp objects to SQL records and back, and provides a Django-inspired simple interface and automatic migrations.

Internally, Crane is very similar in structure to SQLAlchemy, only most of the components SQLAlchemy implements internally are external libraries that Crane depends on. Crane is built mostly on top of fukamachiware: cl-dbi is used to provide a backend-agnostic database abstraction, and SxQL is used as the DSL for generating SQL.

cmacro

cmacro is like sweet.js for C. It implements a simple, pattern-matching based macro language that can be used to extend C.

cmacro is written in Common Lisp, and is compiled to a native binary, so you can drop it right into your Makefile between a file and clang without changing anything.

The companion project, Magma, is a collection of cmacro extensions that shows the scope of the macro system.

Corona

Corona is basically a Vagrant clone. You define virtual machines (Their name, a base system to build from, amount of RAM, IP address, etc.) and Corona sets it up. It uses VirtualBox to run the machines and Vagrant Cloud as a source of base images to build machines from.

The advantage it has over Vagrant is simply that it’s pure Lisp, so it can be used as a dependency in a Common Lisp system, without the user having to set up the Ruby ecosystem to install Vagrant. It’s also pretty nice to use.

Rock

Rock is an asset manager for Common Lisp, basically a combination of Bower plus an asset pipeline. It automatically downloads web development libraries (JavaScript libraries like jQuery, JS/CSS libraries like Bootstrap, etc.), manages their versions, and allows you to merge their files together so you only serve a single CSS file and a single JS one.
