Scheme Implementations

These are many of the freely distributable Scheme implementations. The README files from many of these are available for browsing.

  • Scheme implementations for the Apple IIGS. Good luck with these; I don't have access to a machine to try them out. If you have any more info about these, please let me know.
  • gscheme.shk
  • gscheme05b.shk, by Jawaid Bazyar.
  • The bigloo Scheme system, written by Manuel Serrano (bigloo1.7b.tar.gz). Also available is the camloo package, (camloo0.3.tar.gz) which allows bigloo to compile CAML programs.
  • A compact Scheme system, written by Danny Dube. (bit.tar.gz).
  • The DrScheme System, by Rice University (to obtain, visit the home page for DrScheme).
  • Elk, the Extension Language Kit, by Oliver Laumann (elk-3.0.tar.gz). (Visit the home page for Elk for the distribution, online documentation, and more information about Elk.)
  • Jonathan Lee's Fools lisp system (fools.1.3.2.tar.gz).
  • Galapagos, an interactive multithreaded Scheme interpreter with turtle graphics for Windows 95, based on SCM, by Elad Eyal and Miki Tebeka of Ben-Gurion University of the Negev. The executable and required Scheme libraries (SLIB) (gps10bin.zip); The same with all the source code (gps10src.zip); and the required Windows DLL (mfc40dll.zip).
  • Gambit-C version 2.7, a Scheme system for Unix, Windows-NT/95, MS-DOS, and Macintosh, by Marc Feeley. gambc27.tar.gz contains the sources for Unix, DOS/Windows, and Macintosh.

    Gambit-C also comes prebuilt for DOS/Windows and Macintosh. Since the Gambit-C compiler works in conjunction with the C compiler installed on your computer, you need to get the archive that was built with the C compiler available. Under Windows-NT/95 you can pick any version if you plan to only use the interpreter but the version built with the Watcom C/C++ compiler is suggested because it is the most efficient, roughly twice the speed of the one built with the Microsoft Visual C++ 4.0 compiler. The choices are:

  • gc27-msc.zip contains the pre-built system for Windows-NT/95 and Microsoft Visual C++ 4.0.
  • gc27-bor.zip contains the pre-built system for Windows-NT/95 and Borland C++ 5.0.
  • gc27-wat.zip contains the pre-built system for Windows-NT/95 and Watcom C/C++ 11.0.
  • gc27-dj.zip contains the pre-built system for MS-DOS and DJGPP system v2.0 (see Delorie Software).
  • gc27-cw.hqx contains the pre-built system for MacOS System 7 and the Macintosh CodeWarrior Pro 1 comiler (native 68K and PowerPC).

  • The latest snapshot of the Guile system (guile-ii.tar.gz) from Tom Lord and a host of volunteers.
  • Tanel Tammet's Hobbit Scheme->C compiler (hobbit4d.tar.gz). Requires scm4e1.tar.gz.
  • Kawa, A Scheme implementation written entirely in Java, targeting the Java Virtual Machine, written by Per Bothner. The source is in (kawa-1.2.tar.gz). The compiled version is a zip file, (kawa-1.2-compiled.zip).
  • Brent Benson's libscheme 0.5, a C library implementing Scheme (libscheme-0.5.tar.gz).

  • MIT Scheme version 7.3, by Chris Hanson, Guillermo J. Rozas et al., for a variety of architectures. For older versions, supporting software, etc., check out the Scheme home page at MIT.
  • MIT Scheme version 7.4.2 is available for OS/2, Linux and Microsoft Windows 3.1, Windows 95 and Windows NT. This is the preferred version for these operating systems as it fixes several serious bugs.
  • The MzScheme system, by Matthew Flatt (mzscheme.tar.gz). An editor (mred.tar.gz) is also available.
  • The Oaklisp system, by Kevin Lang and Barak Pearlmutter (oaklisp.tar.gz). The manual (manuals.tar.gz) is available as well.
  • The OScheme (Objective Scheme) system, by Anselm Baird-Smith (oscheme.tar.gz).
  • PCS/Geneva, a Scheme implementation based on TI's PC-Scheme with many enhancements, developed by Larry Bartholdi and Marc Vuilleumier at the University of Geneva. It is available in two formats: as a self-extracting executable (pcscheme.exe) or as a gzipped tar file (pcscheme.tar.gz). The source is available, in the same formats (sources.exe or sources.tar.gz), as well as a FAQ.
  • Texas Instruments' Pc-Scheme, a Scheme implementation which runs on IBM PCs and clones.
