RPC::EPC::Service enables to connect the other process with the S-expression protocol, like the Swank protocol of the SLIME.

libuv is a multi-platform support library with a focus on asynchronous I/O. Among other things, it supports event loops via epoll, kqueue, and similar IOCP, and event ports, asynchronous TCP/UDP sockets, asynchronous DNS resolution, asynchronous file system operations, and threading primitives.

This module allows using a variety of events without forcing module authors to pick a specific event loop, and without noticeable overhead. Currently supported event loops are EV, Event, Glib/Gtk2, Tk, Qt, Event::Lib, Irssi, IO::Async and POE (and thus also WxWidgets and Prima). It also comes with a very fast Pure Perl event loop that does not rely on XS.

GNU Libffcall is a collection of libraries that can be used to build foreign function call interfaces in embedded interpreters.

The libffi library provides a portable, high level programming interface to various calling conventions. This allows a programmer to call any function specified by a call interface description at run-time.

FFI stands for Foreign Function Interface. A foreign function interface is the popular name for the interface that allows code written in one language to call code written in another language. The libffi library really only provides the lowest, machine dependent layer of a fully featured foreign function interface. A layer must exist above libffi that handles type conversions for values passed between the two languages.

Ruby-FFI is a Ruby extension for programmatically loading dynamic libraries, binding functions within them, and calling those functions from Ruby code. Moreover, a Ruby-FFI extension works without changes on Ruby and JRuby.

libFTDI is a library to talk to FTDI chips: FT232BM, FT245BM, FT2232C, FT2232D, FT245R and FT232H including the popular bitbangmode. To use libftdi without root privileges it is necessary to install the necessary udev rules. This can be done by extending udev-service-type in the operating-system configuration file with this package, as in:

(udev-rules-service 'libftdi libftdi #:groups '("plugdev")

Additionally, the plugdev group should be registered in the supplementary-groups field of your user-account declaration. Refer to info "(guix) Base Services" for examples.

Libidn2 is an internationalized domain library implementing the IDNA2008 specifications. Libidn2 is believed to be a complete IDNA2008 implementation, but has yet to be as extensively used as the original Libidn library.

libidn is a library implementing of the Stringprep, Punycode and IDNA specifications. These are used to encode and decode internationalized domain names according to the IDNA2003 specifications. It includes native C, C# and Java libraries.

Hyphen is a hyphenation library using TeX hyphenation patterns, which are pre-processed by a perl script.

Unoconv is a command-line utility to convert documents from any format that LibreOffice can import, to any format it can export. It can be used for batch processing and can apply custom style templates and filters.

Unoconv converts between over a hundred formats, including Open Document Format (.odt, .ods, .odp)), Portable Document Format (.pdf), HTML and XHTML, RTF, DocBook (.xml), .doc and .docx), .xls and .xlsx).

All required fonts must be installed on the converting system.

Orcus is a library that provides a collection of standalone file processing filters. It is currently focused on providing filters for spreadsheet documents. The library includes import filters for Microsoft Excel 2007 XML, Microsoft Excel 2003 XML, Open Document Spreadsheet, Plain Text, Gnumeric XML, Generic XML. It also includes low-level parsers for CSV, CSS and XML.
