From Audacity Development Manual There is also a standalone version of Nyquist available from the Carnegie Mellon University Computer Music Project. Nyquist was written by Roger B. Dannenberg and was intended to be used as a complete programming language for audio synthesis and analysis, with support for MIDI, audio recording and playback, file I/O, object-oriented programming, profiling, debugging and more. Audacity uses a subset of Nyquist's functionality, allowing you to use Nyquist functi

Quirks of Common Lisp Types

news.ycombinator.com Unknown 2025-10-19 09:06:42

By Colin on 2025-08-30 "But I need types," he told me. Humans have a tendency toward binary thinking (pardon the pun). If it's not A, it's B. Perhaps because Lisps have REPLs, they are often thought of from the outside as being dynamic, interpreted languages. Our years of Python have taught us that such languages don't really have strong typing - it's all a wild guess until the interpreter calls foo on a and b and we find out who everyone really is. Yet Common Lisp is fully typed, and AOT com

Seed: Interactive software environment based on Common Lisp

news.ycombinator.com Unknown 2025-11-05 00:57:19

Seed Seed is an interactive software environment. With it you can create and use computer programs in many ways. It is based on the Common Lisp language and runs inside the Web browser, allowing you to build software on a local or remote computer system, and it can present programs and their output using a wide variety of display modes. Seed depicts programs in the form of a tree grid, featuring glyphs that denote different functions and types of data. All of Seed's display modes share basic in

Customizing Lisp REPLs

news.ycombinator.com Artyom Bologov 2025-11-11 02:57:19

Customizing Lisp REPLs Oh, I see you disabled JavaScript. Keep up the good work, my fellow cleanweb person! I am a portability freak. If something can be done with an existing tool, I’ll go for it. If the program can be portable across systems, then it should be. If I can get rid of a tool or a whole class of tools, then off with its head! Sometimes that costs me, but that’s what I am. You can already see why I might dislike custom/wrapper/proxy REPLs. They are a new layer of tools reinventin

A Lisp in 99LOC

news.ycombinator.com Unknown 2025-11-18 06:37:17

Lisp in 99 lines of C and how to write one yourself In honor of the contributions made by Church and McCarthy, I wrote this project and the accompanying article to show how anyone can write a tiny Lisp interpreter in a few lines of C or in any "C-like" programming language for that matter. I attempted to preserve the original meaning and flavor of Lisp as much as possible. As a result, the C code in this project is strongly Lisp-like in compact form. Despite being small, these tiny Lisp interpr

Coalton Playground: Type-Safe Lisp in the Browser

Coalton Playground: Type-Safe Lisp in Your Browser I wanted to share a side project I’ve been tinkering with for a while and finally got around to shipping: Coalton Playground – basically a web-based REPL for Coalton, which is this interesting statically-typed Lisp dialect. So What’s Coalton? If you haven’t heard of it, Coalton is kind of a weird (in a good way) mashup – it takes Haskell’s type system and plants it right in the middle of Common Lisp. You get all the type safety stuff like alg

The "high-level CPU" challenge (2008)

Do you love ("very") high-level languages? Like Lisp, Smalltalk, Python, Ruby? Or maybe Haskell, ML? I love high-level languages. Do you think high-level languages would run fast if the stock hardware weren't "brain-damaged"/"built to run C"/"a von Neumann machine (instead of some other wonderful thing)"? You do think so? I have a challenge for you. I bet you'll be interested. Background: I work on the definition of custom instruction set processors (just finished one). It's fairly high-end

Lurk – A Turing-complete programming language for ZK-SNARKs

news.ycombinator.com Unknown 2025-12-03 03:03:50

Lurk Overview Lurk is a statically scoped dialect of Lisp, influenced by Scheme and Common Lisp. A reference implementation focused on describing and developing the core language can be found in the lurk-lisp repo. Lurk's distinguishing feature relative to most programming languages is that the correct execution of Lurk programs can be directly proved using SNARKs. The resulting proofs are succinct: they are relatively small, can be verified quickly, and they reveal only the information expli

My first take with Eshell many years back did not leave a good impression. My early expectations was that it should act like any other shell, only to be unpleasantly surprised by it. It took a long time for me to warm up to Eshell. Upon reflection, it was because I wasn’t ready for it. Now Eshell is an inseparable part of my Emacs experience. Paradoxically th

Fundamental Problems of Lisp, the Cons Cell (2024)

Fundamental Problems of LISP, the Cons Cell (this essay is originally written around 2008) The Cons Business The other fundamental problem in the language is its cons cells as its list construction primitive. Lisp at core is based on functional programing on lists. This is a powerful paradigm. However, for historical reasons, lisp's list is based on the hardware concept of “cons” cell. From a mathematical, functional, API point of view, what this means is that lisp's “list” is limited to a max
