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.

This package provides facilities for working with .torrent or metainfo files. Implements a bencode reader and writer according to Bitorrent BEP003.

guile-sjson is a json reader/writer for Guile. It has a nice, simple s-expression based syntax.

Guile-colorized provides you with a colorized REPL for GNU Guile.

This package provides Guile bindings to the libsodium cryptographic library which provides core cryptographic primitives needed to build higher-level tools.

guile-sundown is a library that renders Markdown as HTML. It supports many Markdown extensions including tables.

This package provides an implementation of SRFI 158 for Guile. SRFI 158 defines utility procedures that create, transform, and consume generators. It also defines procedures that return accumulators. It is implemented by wrapping the sample implementation in a thin Guile compatibility layer.

guile-jwt is a JSON Web Token module for Guile. JSON Web Tokens are an open, industry standard (RFC 7519) method for representing claims securely between two parties. guile-jwt allows you to decode, verify and generate JWT. Supported algorithms: HS256, HS384, HS512.

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.

This package provides Guile FFI bindings for CBLAS, the library of linear algebra subprograms.

To use the bindings, import (ffi cblas). CBLAS will be loaded from the default dynamic library path. There are up to three bindings for each function: raw, typed, and functional.

Guile Shapefile is a Guile library for reading shapefiles.

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

guile-custom-port overrides Guile's port modules to bring the custom ports from Guile 3.10 to previous versions.

Guile-PG is a collection of modules for Guile allowing access to the PostgreSQL RDBMS from Scheme programs.

This has been tested against PostgreSQL 10 through 13, but currently only works with Guile 1.4.x to 2.0.x.

A module for GNU Guile to read and write YAML files. It works using bindings to the yaml-cpp C++ library.

Guile-Udev provides GNU Guile bindings to libudev.

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.

This is an R6RS Scheme adaptation of the packrat parsing. Packrat parsing is a memoizing, backtracking, recursive-descent parsing technique that runs in time and space linear in the size of the input text.

Jaro is a just another resource opener. It runs the appropriate application to open a given file or URL based on given configurations.

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.

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.

Wisp is a syntax for Guile which provides a Python-like whitespace-significant language. It may be easier on the eyes for some users and in some situations.

This package provides a DSL for a number of Amazon Web Services (AWS) APIs, including EFS, EC2, Route53, and more. Guile AWS uses the Guile compiler tower to generate the DSL from AWS JSON specifications.

GNU Guile QR code generator that can create QR codes from text and binary data. The resulting QR codes can be rendered to ASCII art strings or to PNG images (using Guile-PNG API.)
