Implementing first class functions in a bytecode interpreter is trivial....
After getting angry at Lua for bugs reappearing after fixing them, and otherwise having issues with making it interoperable with my own language of choice (D), I decided to roll out my own VM out, with some enhanced optional features compared to regular Lua (type safety, static arrays on the stack, enhanced metatables, etc.),...
For the last year and a half, I and my recently-added collaborator Jane Losare-Lusby have been working in secret on a safe systems language that could be learned about as quickly as one can learn Go. I think we might have something worth exploring....

This was a conference at MIT that was held 2 days ago. The presentations are all recorded here, and there are summaries and links to the presented papers on the main site....
Algebraic Subtyping is a type system devised by Stephen Dolan in 2016, in his dissertation. It extends Hindley-Milner with subtyping, in a way that preserves decidability and principality. Over the past few years, I have implemented Algebraic Subtyping in my language Pinafore (omitting record types). Pinafore is, as far as I...
These toolchain are created for experts to create industrial-level compilers. Even if you think you got a syntactic design concept that is such hot shit that you can’t wait to get it bootstrapped, even if hell, it proves Rice’s theorem wrong, please, write a simple interpreter for it to prove your syntax works. In fact, I...

Befreak is a purely reversible two-dimensional programming language. It was inspired by the Chris Pressey’s Befunge programming language. Like Befunge, all Befreak instructions are written as a single character, and execution can flow north, south, east, and west....

Today I am pleased to announce Beatrice, which is a finally tagless, dependently typed, self-aware functional programming language that I have been working on for quite a while. In this short blog post, I will demonstrate its most prominent features and contrast them to those of mainstream programming languages....
One of my research group’s major goals is to create technologies that enable self-improving compilers. Taking humans out of the compiler-improvement loop will make this process orders of magnitude faster, and also the resulting compilers will tend to be correct by construction. One such technology is superoptimization, where...
For the past few months I’ve been mulling over some things that Russell Johnston made me realize about the relationship between effect systems and coroutines. You can read more of his thoughts on this subject here, but he made me realize that effect systems (like that found in Koka) and coroutines (like Rust’s async...
A longer article on the different types of parsers and how they work, with a lot of state machine diagrams and some Rust code samples.
Project has been dead for several years but the idea seems interesting....
Hey. I have made some DSLs before, and for all of them, most of which were in C, I have used Flex and Bison. But this time I wanna use Scheme, Cyclone Scheme to be exact. I can potentially use Flex/Bison this time too, because Cyclone has a strong FFI to C....
This article sketches out the syntax for a small language and explains the design decisions....

This essay says that inheritance is harmful and if possible you should “ban inheritance completely”. You see these arguments a lot, as well as things like “prefer composition to inheritance”. A lot of these arguments argue that in practice inheritance has problems. But they don’t preclude inheritance working in another...
