• R⁷RS large edition (in progress)
• SRFI (Scheme Requests for Implementation)

Implementations

Compiling to Native Code

• Chez Scheme: R6RS, official installer also for Windows, considered one of the fastest scheme implementations.
• Ikarus R6RS
• MIT/GNU Scheme: R7RS

Based on Another Scheme

• Gerbil: R7RS, compiles to C, based on Gambit, extends gambit with better macro and module systems.
• Racket: R6RS, beginner friendly, full Windows support, optional typing, essentially a superset of scheme, tons of libraries, moving/moved to a Chez Scheme backend.

Compiling to C

• CHICKEN: R5RS and R7RS, beginner friendly, exceptional community, unique implementation of GC.
• Cyclone: R7RS, experimental extension of Chicken-style GC with native thread support.
• Gambit: R5RS, official installers also for macOS, iOS, Windows, considered quite fast.
• Bigloo: R5RS, can also compile to Java-Virtual-Machine (JVM) classes, limited optional typing.

Bytecode VMs and JVM/CLR

• Chibi-Scheme: R7RS
• Gauche: R7RS, compiles to standalone executable, official installers also for Windows, Docker.
• GNU Guile: R6RS, getting JIT executable support soon, beginner friendly, officially supported by GNU, scripting language for many pieces of GNU software.
• IronScheme: R6RS, based on Common-Language-Runtime (CLR).
• Kawa: R7RS, based on JVM, compile to JVM classes, limited optional typing.
• Skint: R7RS-small, easily portable (Un*x, MacOS, Windows), fast threaded-code VM
• STklos: R7RS except that syntax-rules only has partial hygiene and lexical scope; ad-hoc portable VM, with CLOS-like object system.

Based on JavaScript

• BiwaScheme: R6RS, partial R7RS, compiler to intermediate represantion + VM
• LIPS: R7RS, most of the spec is written in core Scheme, good interop with JavaScript

Implemented in Python

• Calysto Scheme: Partial R6RS, written in Scheme, transpiled to Python.

Package Managers

• Akku: for portable R6RS and R7RS libraries
• Snow: for portable R7RS libraries
• GNU Guix: purely-functional package manager and GNU/Linux distro
• Racket Packages: for Racket libraries and applications

Books

• Structure and Interpretation of Computer Programs: classic computer science textbook from MIT
• How to Design Programs: an easier-to-approach, more down-to-earth counterpart to SICP
• The Little Schemer: teaches recursive thinking using Scheme (code)
• The Seasoned Schemer: continuation of The Little Schemer (code)
• The Reasoned Schemer: teaches logic programming using Scheme (code)
• The Scheme Programming Language: language reference by the author of Chez Scheme
• Essentials of Programming Languages: textbook on programming language implementation

Research Papers

• Bibliography of Scheme research

Editors and IDEs

• Geiser: most comprehensive Emacs support for many Scheme implementations (MELPA)
• Scheme-langserver: a new scheme language server focusing on digesting incomplete scheme source code and giving out useful language features. It's different from other REPL counterparts for it provides local identifier auto complete and many other functionalities.

Applications

• GNUCash: personal finance app scriptable in Guile
• SIAG: Scheme In A Grid: old Scheme-scriptable spreadsheet with built-in web server

Web Development

• SXML: very popular S-expression representation of XML/HTML
• CSS-expressions: S-expression representation of CSS (Racket)
• chibi html-parser: lenient HTML parser (R7RS; Docs; Akku, Snow)

Text Processing

• Scribble: popular, somewhat lightweight Scheme-based markup language (Racket, R7RS)
• Skribilo: TeX/LaTeX-like document processor with Scheme scripting
• Skribe and Scheme Scribe: older Scheme-based document processors from INRIA
• Pollen: a fancy typesetting system for writing entire books in Racket

Graphics, Music, Audio, Video

• LilyPond: music notation language with Scheme scripting
• libfive: script-driven solid modeling CAD based on Guile
• Fluxus: portable 3D game engine for live coding in Scheme
• Impromptu: live coding with Scheme on macOS
• Extempore: portable live coding in Scheme
• Scheme For Max: live coding with Scheme in Max/MSP

Languages and Computation

• Nanopass Framework: a DSL for factoring compilers into many small passes and IRs
• Harlan: a Scheme-based programming language for GPU computing
• packrat: a PEG parser generator with a Scheme DSL (Akku, Chicken, Racket)
• r6rs-pffi - portable foreign-function interface for several implementations (R6RS; Home & Docs; Akku)
