The Scheme Programming Language, 3rd Edition

The Scheme Programming Language, 3rd Edition

Squeak by Example Structure and Interpretation of Computer Programs A powerful programming language is more than just a means for instructing a computer to perform tasks. The language also serves as a framework within which we organize our ideas about processes. Thus, when we describe a language, we should pay particular attention to the means that the language provides for combining simple ideas to form more complex ideas. Every powerful language has three mechanisms for accomplishing this: primitive expressions, which represent the simplest entities the language is concerned with,means of combination, by which compound elements are built from simpler ones, andmeans of abstraction, by which compound elements can be named and manipulated as units. In programming, we deal with two kinds of elements: procedures and data. In this chapter we will deal only with simple numerical data so that we can focus on the rules for building procedures.4 In later chapters we will see that these same rules allow us to build procedures to manipulate compound data as well.

Programming in Lua : contents This book is a detailed and authoritative introduction to all aspects of Lua programming written by Lua's chief architect. Programming in Lua provides a solid base to any programmer who wants to use Lua. It covers all aspects of Lua—from the basics to its API with C. The book is the main source of programming patterns for Lua, with numerous code examples that help the reader to make the most of Lua's flexibility and powerful mechanisms. When you buy a copy of this book, you help to support the Lua project. For the official definition of the Lua language, see the reference manual. Fourth edition The fourth edition updates the book to Lua 5.3 and marks a complete reorganization of the text. The book is available at the main online stores and also as an e-book. Third edition The third edition is aimed at Lua 5.2 and can be used with other versions. The book is available at the main online stores and also as an e-book. Second edition The book is still available at the main online stores.

Simple Scheme, for Android I was on the train, wanted to write some code, and I though, "I wonder if there are any good Scheme implementations for my phone?". I didn't find any that were simple, easy to use, and efficient (the first one I installed crashed my phone). I also wanted to be able to write graphical and interactive programs easily (see image examples and/or big-bang/interaction examples). So... I started an implementation of all the major features I could think of (see traditional Scheme forms and examples). The execution needed to be tail-recursive, and even non-tail-recursive functions shouldn't run out of stack space, so I implemented a continuation-passing style interpreter with efficient binding and lookup. While I tried to remain faithful to the term "Scheme-like", I made a few changes to the language (and the implementation) to make the it a little easier. Like traditional Scheme, Simple Scheme supports define, define-struct, begin, let, and many other forms/expressions. Simple stuff... Symbols...

Frink What's New * FAQ * Download * Frink Applet * Web Interface * Sample Programs * Frink Server Pages * Frink on Android * Donate About Frink Frink is a practical calculating tool and programming language designed to make physical calculations simple, to help ensure that answers come out right, and to make a tool that's really useful in the real world. It tracks units of measure (feet, meters, kilograms, watts, etc.) through all calculations, allowing you to mix units of measure transparently, and helps you easily verify that your answers make sense. It also contains a large data file of physical quantities, freeing you from having to look them up, and freeing you to make effortless calculations without getting bogged down in the mechanics. Perhaps you'll get the best idea of what Frink can do if you skip down to the Sample Calculations further on this document. Frink was named after one of my personal heroes, and great scientists of our time, the brilliant Professor John Frink. Features

Programming Pearls by Jon Bentley. Addison-Wesley, Inc., 2000. ISBN 0-201-65788-0. 239 + xi pp. $24.95 This book is a collection of essays about a glamorous aspect of software: programming pearls whose origins lie beyond solid engineering, in the realm of insight and creativity. The book is full of small case studies, real examples, and interesting exercises for learning about how to program. Steve McConnell describes the book as ``a celebration of design in the small''.
