The SCM Implementation of Scheme

Current Version Released Terms
5f1 2013-05-10 LGPL

SCM is a Scheme implementation conforming to Revised5 Report on the Algorithmic Language Scheme and the IEEE P1178 specification*.   Scm is written in C and runs under Amiga, Atari-ST, GNU/Linux, MacOS, MS-DOS, MS-Vista, MS-Windows, OS/2, NOS/VE, Unicos, VMS, Unix and similar systems.

SCM includes Hobbit, the Scheme-to-C compiler originally written by Tanel Tammet. Hobbit generates C files whose binaries can be dynamically or statically linked with a SCM executable. SCM includes linkable modules for sequence-comparison, arrays, records, and byte-number conversions; and modules for POSIX system calls and network-sockets, readline, ncurses, and Xlib.

On some platforms SCM supports unexec (developed for Emacs and bash), which dumps a executable image from a running SCM. This results in very low latency (12.ms) startup for SCM.

SCM requires the SLIB Scheme Library. Both SCM and SLIB are GNU packages.
