1.3 KiB

Chibi-Scheme is a very small library with no external dependencies intended for use as an extension and scripting language in C programs. In addition to support for lightweight VM-based threads, each VM itself runs in an isolated heap allowing multiple VMs to run simultaneously in different OS threads. The default language is R7RS Scheme, including first-class continuations and low-and-high-level hygienic macros.

The current release is 0.7.2, "Nitrogen":

This includes the following changes:

  • R7RS now the default language
  • Initial Snow2 package manager
  • Faster bignum arithmetic
  • Scheme Regular Expression support (SRFI 115)
  • Flexible and memoizable parse combinator library
  • Interning and smarter handling of file descriptors
  • Many bugfixes and new tests

and many others. Most features are optional at compile time. A full-featured build produces a library around 200kb, whereas a minimal build can be under 80kb.

Chibi-Scheme is known to work on 32 and 64-bit Linux, FreeBSD and OS X, Plan9, Windows (using Cygwin) and iOS.

Future releases should come at a faster pace now. Near-term goals include native x86 support, batch compilation, and alternate language support.
