chibi-scheme - Project Hosting on Google Code
Minimal Scheme Implementation for use as an Extension Language http://synthcode.com/wiki/chibi-scheme Chibi-Scheme is a very small library intended for use as an extension and scripting language in C programs. In addition to support for lightweight VM-based threads, each VM itself runs in an isolated heap allowing multiple VMs to run simultaneously in different OS threads. There are no external de
Hoot: Scheme to WebAssembly -- Spritely Institute
Hoot is a Spritely project which provides a full-featured WebAssembly (Wasm) toolkit in Scheme. Hoot includes a Scheme to Wasm compiler, allowing Scheme code to run in recent browsers as a first-class citizen. Hoot requires no external tools and provides its own Wasm assembler and linker, and additionally contains a fully featured development environment including a disassembler, interpreter, and
Directly compiling Scheme to WebAssembly: lambdas, recursion, iteration! -- Spritely Institute
It's been just over three months since we announced the Guile on WebAssembly project (codenamed Hoot). Since then we've brought on two fantastic hackers to develop the project and progress has been quick. We now are at the point where we have things to show: we can now compile various Scheme procedures directly to WebAssembly. Let's clarify that: by compiling directly to WebAssembly, we mean they
Racket v8.4
posted by John Clements Racket version 8.4 is now available from https://download.racket-lang.org. Command-line Racket provides a new expression editor by default for its read-eval-print loop (REPL). The new REPL is based on the Chez Scheme expression editor, but extended to use the same language-sensitive syntax coloring and indentation tools as DrRacket. Typed Racket adds a kind system, preventi

Hal Abelson's, Jerry Sussman's and Julie Sussman's Structure and Interpretation of Computer Programs (MIT Press, 1984; ISBN 0-262-01077-1), an excellent computer science text used in introductory courses at MIT.

Scheme/継続の種類と利用例 - Wikibooks
Introduction[編集] このセクションでは、継続を用いたプログラムを実際に動かしてみる。教科書の例題を解くためだけでなく、制御処理の仕組みを継続を活用して作ったり、既存のライブラリの動作をカスタマイズすることで実用的なプログラミングに応用できるようになることを目指す。また、処理系における実装の方法についても触れ、継続呼び出しのパフォーマンスについても考察する予定。 call/cc[編集] 導入[編集] call/ccは、(call/cc proc) 式を評価した後すべき計算を、継続オブジェクトとして proc に渡す手続きである。 この継続オブジェクトは、C言語で考えると (call/cc proc) を評価した後の処理へgotoするマクロ、もしくは (call/cc proc) を評価したときに setjmp() によってマークした地点に longjmp() によって移動する関
Clojure from a Schemer's perspective | More magic
Recently I joined bevuta IT, where I am now working on a big project written in Clojure. I'm very fortunate to be working in a Lisp for my day job! As I've mostly worked with Scheme and have used other Lisps here and there, I would like to share my perspective on the language. Overall design From a first view, it is pretty clear that Clojure has been designed from scratch by (mostly) one person wh

call/cc 入門 (Coroutine with call/cc) - MAYAH
call/cc を使って簡単な Coroutine を作ります。call/cc 入門だと思ってもらえれば幸いです。 coroutine とは ここでは coroutine を「実行の途中でリターンでき、さらにそこ(実行の途中)から再開することが出来る何か」の意味で使用します。適当な疑似言語で書くと次の通り。関数の途中でのリターンを suspend(), 途中からの再開を resume() で表すことにします。 ここでは、これを scheme の call/cc を用いて表すことを目指します。 call/cc とは call/cc とは、call-with-current-continuation という scheme の関数で、「現在の継続(current continuation)を生成し、それを関数に渡してその関数を実行する」ものです。読者の殆どは「継続」についてよく知っているかもしれ
The Scheme Programming Language
Welcome to Scheme.org, a new home page for Scheme. We host a snapshot of the old Schemers.org. Thanks to Prof. Shriram Krishnamurthi and all the other people who gave Scheme a home on Schemers.org for nearly twenty-five years. Scheme is a classic programming language in the Lisp family. It emphasizes functional programming and domain-specific languages but adapts to other styles. Known for its cle
