Synopsis: R6RS Scheme compiler and run-time
Description:

Chez Scheme is both a programming language and a high-performance implementation of that language. The language is a superset of R6RS Scheme with numerous extensions, including native threads, non-blocking I/O, local modules, and much more. Chez Scheme compiles source expressions incrementally to machine code, providing the speed of compiled code in an interactive system. The system is intended to be as reliable and efficient as possible, with reliability taking precedence over efficiency if necessary.

Licenses: Expat
Synopsis: LaTeX with embedded Scheme code and HTML generation
Description:

The stex package extends LaTeX with a handful of commands for including Scheme code (or pretty much any other kind of code, as long as you don't plan to use the Scheme-specific transcript support) in a document. It provides the programs scheme-prep and html-prep to convert stex documents to LaTeX and HTML, respectively, plus makefile templates, style files, and other resources. The stex system is used to typeset The Scheme Programming Language and the Chez Scheme User's Guix, among other documents.

chez-nanopass 1.9.2
Channel: guix
Location: gnu/packages/chez.scm (gnu packages chez)
Home page: https://nanopass.org
Licenses: Expat
Synopsis: DSL for compiler development
Description:

The Nanopass framework is an embedded domain-specific language for writing compilers composed of several simple passes that operate over well-defined intermediate languages. The goal of this organization is both to simplify the understanding of each pass, because it is responsible for a single task, and to simplify the addition of new passes anywhere in the compiler. Nanopass reduces the boilerplate required to create compilers, making them easier to understand and maintain.

chez-scheme-bootstrap-bootfiles 10.2.0
Channel: guix
Location: gnu/packages/chez.scm (gnu packages chez)
Home page: https://cisco.github.io/ChezScheme/
Licenses: ASL 2.0
Synopsis: Bootstrapped Chez Scheme boot files
Description:

Chez Scheme is a self-hosting compiler: building it requires ``boot files'' containing the Scheme-implemented portions compiled for the current platform. (Chez can then cross-compile bootfiles for all other supported platforms.)

This package provides boot files for the released version of Chez Scheme bootstrapped by chez-scheme-for-racket. Chez Scheme 9.5.4 or any later version can be used for bootstrapping. Guix ultimately uses the Racket package cs-bootstrap to bootstrap its initial version of Chez Scheme.

chez-nanopass 1.9.3
Channel: guix
Location: gnu/packages/chez.scm (gnu packages chez)
Home page: https://nanopass.org

The goal of this organization is both to simplify the understanding of each pass, because it is responsible for a single task, and to simplify the addition of new passes anywhere in the compiler.

chez-scheme-for-racket-bootstrap-bootfiles 10.3.0-pre-release.2
Channel: guix
Location: gnu/packages/chez.scm (gnu packages chez)
Home page: https://pkgs.racket-lang.org/package/cs-bootstrap
Licenses: ASL 2.0
Synopsis: Chez Scheme boot files bootstrapped by Racket
Description:

Chez Scheme is a self-hosting compiler: building it requires ``boot files'' containing the Scheme-implemented portions compiled for the current platform. (Chez can then cross-compile boot files for all other supported platforms.)

The Racket package cs-bootstrap (part of the main Racket Git repository) implements enough of a Chez Scheme simulation to load the Chez Scheme compiler purely from source into Racket and apply the compiler to itself, thus bootstrapping Chez Scheme. Bootstrapping takes about 10 times as long as using an existing Chez Scheme, but cs-bootstrap supports Racket 7.1 and later, including the Racket BC variant.

chez-srfi 1.0
Channel: guix
Location: gnu/packages/chez.scm (gnu packages chez)
Home page: https://github.com/fedeinthemix/chez-srfi
Licenses: Expat
Synopsis: SRFI libraries for Chez Scheme
Description:

This package provides a collection of SRFI libraries for Chez Scheme.

chicken-srfi-13 0.3.2
Propagated dependencies: chicken-srfi-14@0.2.1
Channel: guix
Location: gnu/packages/chicken.scm (gnu packages chicken)
Home page: https://wiki.call-cc.org/egg/srfi-13

Location: gnu/packages/chicken.scm (gnu packages chicken)
Home page: https://wiki.call-cc.org/egg/srfi-18
Licenses: Modified BSD
Synopsis: Multithreading package, largely following SRFI-18
Description:

The threads implemented in CHICKEN are so called "green" threads, based on first-class continuations. Native threads that map directly to the threads provided by the operating system are not supported. The advantage of this is that threads are very lightweight and somewhat larger degree of determinism. The disadvantage is that execution of Scheme code on multiple processor cores is not available.
