The EdScheme Interpreter

EdScheme is an efficient yet powerful Scheme interpreter for the personal computer. Students and hobbyists alike will quickly find themselves in a friendly and convenient interactive programming environment. It comes as a complete, self-contained package with a built-in language-sensitive editor and exhaustive documentation. This simple yet robust interpreter is available on the Windows and Macintosh platforms. The EdScheme interpreter is the perfect companion for students studying "The Schemer's Guide" or any of the other publications distributed by Schemers Inc.

EdScheme combines power with ease of use:

• It features a fully-integrated editor – on the Windows platform, the WinScheme Editor – with automatic indentation and parenthesis-matching.
• It is 100% compliant with the Revised⁴ Report on the Algorithmic Language Scheme (R4RS).
• It supports advanced functional programming techniques and object-oriented programming.
• It includes a versatile turtle graphics interface that gives easy-to-use access to sophisticated, two-dimensional color vector graphics as well as providing some common ground with more elementary programming experiences using languages such as LOGO.
• It has comprehensive file-handling facilities as well – on the Macintosh platform – as access through the serial port to external devices such as the Hyperbot robotic controller.
• It includes a macro system that allows for syntax extensions.
• It provides extensive debugging facilities and detailed error messages that help you track down the source of any errors you might make.
• It features unlimited precision "bignum" integral arithmetic.
• It supports complex numbers, exact rational numbers, and the exact/inexact distinction.

EdScheme comes with a wide selection of Scheme code files. You can examine this sample code, using the built-in editor, to discover how to achieve a variety of results by means of the Scheme language.

Version 5.0 of EdScheme for Windows also provides:

• dynamic syntax help at the foot of each Scheme document window, displaying syntax templates that change "on the fly" in accordance to what you type and where you place the cursor
• powerful, Windows-based debugging tools
• a compendious multimedia on-line knowledge base that incorporates a full-text version of the R4RS report in hypertext form
• Scheme access to the Windows application procedural interface (API)
• automatically self-indexing Scheme document windows
• the ability to color-code each syntactic element in a distinctive way.

Download a fully-functional copy of this powerful product and try it out, free of charge, for fourteen days – long enough to develop a taste for EdScheme's genuinely user-friendly Scheme programming environment!

The Macintosh version of EdScheme is supplied with a comprehensive, fully-indexed User's Reference Manual that carefully explains the implementation. The Windows version comes with a Quick Reference Manual to the Scheme language and an extensive on-line help system that documents both the Scheme language and the operation of the WinScheme Editor in great detail.
