Googleスプレッドシートの名前付き関数でLISPインタプリタを作った
Googleスプレッドシートの名前付き関数でLISPインタプリタを作った はじめに こんなの を作った。 エラーチェックをサボっていたり、 少し複雑な計算をすると途中で打ち切られたりするが、 それなりに遊べるはず。 Googleスプレッドシートとは Googleスプレッドシートはいわゆる表計算ソフト。 表に色々入力したり、色々計算させたりする。 =SUM(A2:A10) とか書くと2行A列から10行A列までの合計を計算してくれたりする。 スクリーンショットを貼り付けるためのソフトではないはず。 名前付き関数とは Googleスプレッドシートには前述のSUMの他にも色々関数があるが、 ユーザが自分で新しい関数を定義することもでる。 例えばNの階乗を求める関数を定義してみよう。 メニューの [データ] - [名前付き関数] を選択し、 [新しい関数を追加] をクリック。 [関数名] に FA
[PDF] Evolution of Emacs Lisp
74 Evolution of Emacs Lisp STEFAN MONNIER, Université de Montréal, Canada MICHAEL SPERBER, Active Group GmbH, Germany Shepherd: Brent Hailpern, IBM Research, USA While Emacs proponents largely agree that it is the world’s greatest text editor, it is almost as much a Lisp machine disguised as an editor. Indeed, one of its chief appeals is that it is programmable via its own programming language. Em
Bel
Oct 2019 Bel is a spec for a new dialect of Lisp, written in itself. This should sound familiar to people who know about Lisp's origins, because it's the way Lisp began. It consists of two text files meant to be read in parallel: a guide to the Bel language, and the Bel source. For those who just want to see some code examples, there's a file of those. But of course the Bel source is also a code e
And now for something completely different: running Lisp on GPUs
The internal parallelism of compute resources increases permanently, and graphics processing units (GPUs) and other accelerators have been gaining importance in many domains. Researchers from life science, bioinformatics or artificial intelligence, for example, use GPUs to accelerate their computations. However, languages typically used in some of these disciplines often do not benefit from the te
Emacs Lisp Lambda Expressions Are Not Self-Evaluating
This week I made a mistake that ultimately enlightened me about the nature of function objects in Emacs Lisp. There are three kinds of function objects, but they each behave very differently when evaluated as objects. But before we get to that, let’s talk about one of Emacs’ embarrassing, old missteps: eval-after-load. Taming an old dragon One of the long-standing issues with Emacs is that loading
GitHub - vygr/ChrysaLisp: Parallel OS, with GUI, Terminal, OO Assembler, Class libraries, C-Script compiler, Lisp interpreter and more...
ChrysaLisp ChrysaLisp is a 64-bit, MIMD, multi-CPU, multi-threaded, multi-core, multi-user parallel operating system with features such as a GUI, terminal, OO Assembler, class libraries, C-Script compiler, Lisp interpreter, debugger, profiler, vector font engine, and more. It supports MacOS, Windows, and Linux for x64, Riscv64 and Arm64 and eventually will move to bare metal. It also allows the mo
A few things I know about LISP Machines
A few things I know about LISP Machines I wanted to know what LISP Machines (LispM) were like, so I bought one. Since I learnt many things about them in the process that were not documented anywhere on the web, I thought I'd write a page about them. Most of the material I publish is just trivia or curiosity; for more useful or spectacular stuff, follow the provided pointers. If you like my prose,
Practical advice for real-world web development with Racket
Racket’s a great language, and its HTTP server is a delight to work with. Racket’s approach can, at times, appear somewhat unusual (and not just for newcomers). I made this site, and my ebook Server: Racket, to help you get into web development with Racket, whether you’re fresh to the scene or coming in with previous experience in other programming languages & web deve
LispmFPGA
The goal of this project is to create a small Lisp-Machine in an FPGA. The hardware will be defined in the Verilog language on a Spartan 3 Xilinx FPGA The concrete system I am working with is the Spartan 3 Starter Kit from Digilent The core of the project is designing a CPU with Lisp optimized instruction set together with a complete set of system software written in Lisp The CPU is mostly ready a
Building a LISP from scratch with Swift
Some say that building a small language interpreter, especially if a LISP, is one of those things you have to do at least one time in your life as a programmer, an eye opening experience that will give you new insights into how the tools you use everyday work and demystify a few concepts that seem daunting when seen from afar. In this article, we’ll implement a minimal LISP based on the 1978 paper
The origin of CAR and CDR in LISP
The origin of CAR and CDR in LISP A discussion in alt.folklore.computers, that started with a question from someone: The use of the keywords CAR and CDR to denote the head and tail of a list in LISP has always struck me as odd, (To which Iain A F Fleming replied: I have always, and still do, use car and cdr as content and forward pointer, even in C. ) According to the LISP 1.5 Programmer's Manual
Parinfer - simpler Lisp editing
Introduction Lisp is often dismissed as an undesirable programming syntax due to excessive parentheses. Those who have adopted Lisp have long recognized its amazing strengths, but there is still a widely held uncertainty among newcomers about how or even why we must manage so many parens. As a result, Lisp's unique power remains invisible to most under this guise of difficulty. Newcomers aren't sa
2016年の抱負: Emacs Lisp を書く会社を立ち上げる - だるい
私には、Emacs Lisp によるウェブアプリケーション開発シーンを盛り上げていきたいという熱い想いがあります。 最近、「次に来る大物Web言語」と称され Elixir などが注目されている様子が伺えますが、ウェブアプリケーションのサーバーサイド実装において次に来る言語というのであれば、個人的には Emacs Lisp こそを推していきたいと思います。なぜなら Emacs Lisp には、インタプリタでありそして同時にプログラミング環境でもある Emacs というソフトウェアが存在するからです。Emacs と最も親和性が高く、最もプラグインが豊富な言語こそが Emacs Lisp です。これを単なる Emacs の設定やプラグインを記述するための言語に留めておくには惜しいと言えるでしょう。 残念ながら現状 Emacs Lisp でのウェブアプリケーション開発は全くといって注目されていない

Common Lisp Koans is a language learning exercise in the same vein as the ruby koans, python koans and others. It is a port of the prior koans with some modifications to highlight lisp-specific features. Structured as ordered groups of broken unit tests, the project guides the learner progressively through many Common Lisp language features. License
