This package provides a robust CSV parser and printer that tries to follow the fine print of de facto standards. It can be configured to choose which standard exactly.

This library provides GTK4 bindings for Common Lisp via Gobject Introspection, in the cl-gtk4 ASDF system.

This package provides an implementation of the hash-set data structure. It has constant time lookup, insertion and deletion.

This package contains the specification of all functions and variables from GLSL as data.

IOlib is to be a better and more modern I/O library than the standard Common Lisp library. It contains a socket library, a DNS resolver, an I/O multiplexer(which supports select(2), epoll(4) and kqueue(2)), a pathname library and file-system utilities.

The canonical way to determine the size of a file in bytes, using Common Lisp, is to open the file with an element type of (unsigned-byte 8) and then calculate the length of the stream. This is less than ideal. In most cases it is better to get the size of the file from its metadata, using a system call.

This library exports a single function, file-size-in-octets. It returns the size of a file in bytes, using system calls when possible.

This package provides an extensible implementation of defclass that can accurately control the expansion according to the metaclass and automatically detect the suitable metaclass by analyzing the defclass form.

Parse INI formatted files into a Common Lisp list structure.

Salza2 is a Common Lisp library for creating compressed data in the zlib, deflate, or gzip data formats, described in RFC 1950, RFC 1951, and RFC 1952, respectively.

The GRAPH Common Lisp library provides a data structures to represent graphs, as well as some graph manipulation and analysis algorithms (shortest path, maximum flow, minimum spanning tree, etc.).

An implementation of Relax NG schema validation written in Common Lisp, including support for compact syntax, DTD Compatibility, and the XSD type library.

This is a Common Lisp library which provides functionality to read/write Bit Map Font (BMF) into text, JSON and XML.

This library strives to provide a portable TCP/IP and UDP/IP socket interface for as many Common Lisp implementations as possible, while keeping the abstraction and portability layer as thin as possible.

This is a collection of common cryptography functions for Common Lisp.

cl-amb provides an implementation of John McCarthy's ambiguous operator in portable Common Lisp.

This package provides an ANSI CL adaptation of the SBCL mailbox utility.

This package provides Common Lisp bindings to create OpenGL window and context manipulation code as well as system input handling. Direct FFI bindings to system functions are used so no third party C lib is required except system libraries.

Parse-js is a Common Lisp package for parsing JavaScript (ECMAScript 3). It has basic support for ECMAScript 5.

This package is a simple date and time library.

This library contains utilities for parsing Common Lisp code.

Common Lisp comes with quite some functions to compare objects for equality, yet none is applicable in every situation and in general this is hard, as equality of objects depends on the semantics of operations on them. As consequence, users find themselves regularly in a situation where they have to roll their own specialized equality test.

This module provides one of many possible equivalence relations between standard Common Lisp objects. However, it can be extended for new objects through a simple CLOS protocol. The rules when two objects are considered equivalent distinguish between mutating and frozen objects. A frozen object is promised not to be mutated in the future in a way that operations on it can notice the difference.

We have chosen to compare mutating objects only for identity (pointer equality), to avoid various problems. Equivalence for frozen objects on the other hand is established by recursing on the objects' constituent parts and checking their equivalence. Hence, two objects are equivalent under the OBJECT= relation, if they are either identical, or if they are frozen and structurally equivalent, i.e. their constituents are point-wise equivalent.

Since many objects are potentially mutable, but are not necessarily mutated from a certain point in their life time on, it is possible to promise to the equivalence relation that they remain frozen for the rest of their life time, thus enabling coarser equivalence than the often too fine-grained pointer equality.

This package provides functions for base32 encoding and decoding as defined in RFC4648.

With lispy syntax, shortcuts, and improvements, LASS aims to help you out in writing CSS quick and easy. LASS was largely inspired by SASS. LASS supports two modes, one being directly in your lisp code, the other in pure LASS files.

This package provides a consolidation of Common Lisp statistics libraries.
