G-Wrap is a tool and Guile library for generating function wrappers for inter-language calls. It currently only supports generating Guile wrappers for C functions. Given a definition of the types and prototypes for a given C interface, G-Wrap will automatically generate the C code that provides access to that interface and its types from the Scheme level.

Guile Config is a library providing a declarative approach to application configuration specification. The library provides clean configuration declaration forms, and processors that take care of: configuration file creation; configuration file parsing; command-line parameter parsing using getopt-long; basic GNU command-line parameter generation (--help, --usage, --version); automatic output generation for the above command-line parameters.

Guile-Daemon is a small Guile program that loads your initial configuration file, and then reads and evaluates Guile expressions that you send to a FIFO file.

This package provides purely functional data structures written in R6RS Scheme and compiled for Guile. It has been tested with Racket, Guile 2, Vicare Scheme and IronScheme. Right now it contains:

• queues

• deques

• bbtrees

• sets

• dlists

• priority search queues (PSQs)

• finger trees

• sequences

• heaps

• hash array mapped tries (HAMTs).

This package provides a simple yaml module for Guile using the ffi-helper from nyacc.

This package provides Guile bindings for the taglib C library. It can be used to access and modify metadata for audio files.

Guile-Bash provides a shared library and set of Guile modules, allowing you to extend Bash in Scheme. Scheme interfaces allow you to access the following aspects of Bash:

• aliases;

• setting and getting Bash variables;

• creating dynamic variables;

• creating Bash functions with a Scheme implementation;

• reader macro for output capturing;

• reader macro for evaluating raw Bash commands.

To enable it, run:

enable -f ~/.guix-profile/lib/bash/libguile-bash.so scm

and then run scm example.scm.

This is a minimal set of Guile FFI bindings for the FFTW library's ‘guru interface’. It provides two functions: fftw-dft! rank sign in out and fftw-dft rank sign in. These bindings being minimal, there is no support for computing & reusing plans, or split r/i transforms, or anything other than straight complex DFTs.

This package provides A Guile reader extension for `raw strings', it lets you write verbatim strings without having to escape double quotes.

Guile-ICS is an iCalendar (RFC5545) and vCard (RFC6350) format parser library written in pure Scheme. The library can be used to read and write iCalendar/vCadr data and convert the data from/to various formats.

The library is shipped with documentation in Info format and usage examples.

This package provides a Guile Scheme wrapper for libgsl.so. Implements

• GSL vectors.

• Matrices.

• BLAS operations.

• Eigensystem solutions.

• One-dimensional root solvers.

Hall is a command-line application and a set of Guile libraries that allow you to quickly create and publish Guile projects. It allows you to transparently support the GNU build system, manage a project hierarchy & provides tight coupling to Guix.

guile-newra (newra) wants to replace the current (3.0) Guile array system, which is almost entirely implemented in C. The new implementation should be at least as fast.

Guile-Udev provides GNU Guile bindings to libudev.

Guile-DSV is a GNU Guile module for working with the delimiter-separated values (DSV) data format. Guile-DSV supports the Unix-style DSV format and RFC 4180 style format. Also Guile-DSV includes a console program named dsv that allows to view and process DSV data, including such operations as delimiter change, conversion from one DSV standard to another and printing the data as pseudographics tables.

This Guile library provides tools for reading, comparing, and writing Semantic Versions. It also includes ranges in the style of the Node Package Manager (NPM).

guile-xapian provides Guile bindings for Xapian, a search engine library. Xapian is a highly adaptable toolkit which allows developers to easily add advanced indexing and search facilities to their own applications. It has built-in support for several families of weighting models and also supports a rich set of boolean query operators.

Guile-Lens is a library implementing lenses in Guile. The library is currently a re-implementation of the lentes library for Clojure. Lenses provide composable procedures, which can be used to focus, apply functions over, or update a value in arbitrary data structures.

Guildhall is a package manager written for Guile Scheme. A guild is an association of independent craftspeople. A guildhall is where they meet. This Guildhall aims to make a virtual space for Guile wizards and journeyfolk to share code.

On a practical level, Guildhall lets you share Scheme modules and programs over the internet, and install code that has been shared by others. Guildhall can handle dependencies, so when a program requires several libraries, and each of those has further dependencies, all of the prerequisites for the program can be installed in one go.

The (jtd) module for Guile provides a procedure jump-to-debugger for escaping to the Guile REPL for the purpose of debugging code.

Fortran is great in expressing operations on multi-dimensional arrays of numbers. Scheme is great at expressing your coding thoughts. This project is an attempt to combine both into something useful.

GNU 8sync (pronounced "eight-sync") is an asynchronous programming library for GNU Guile based on the actor model.

Guile-Reader is a simple framework for building readers for GNU Guile.

The idea is to make it easy to build procedures that extend Guile’s read procedure. Readers supporting various syntax variants can easily be written, possibly by re-using existing “token readers” of a standard Scheme readers. For example, it is used to implement Skribilo’s R5RS-derived document syntax.

Guile-Reader’s approach is similar to Common Lisp’s “read table”, but hopefully more powerful and flexible (for instance, one may instantiate as many readers as needed).

guile-aspell is a Guile Scheme library for comparing a string against a dictionary and suggesting spelling corrections.
