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.

Lack is a Common Lisp library which allows web applications to be constructed of modular components. It was originally a part of Clack, however it's going to be rewritten as an individual project since Clack v2 with performance and simplicity in mind.

Provides a simple way of directing output to a stream according to the concise and intuitive semantics of FORMAT's stream argument.

cl-irc is a Common Lisp IRC client library that features (partial) DCC, CTCP and all relevant commands from the IRC RFCs (RFC2810, RFC2811 and RFC2812).

Features:

• implements all commands in the RFCs

• extra convenience commands such as op/deop, ban, ignore, etc.

• partial DCC SEND/CHAT support

• event driven model with hooks makes interfacing easy

• the user can keep multiple connections

• all CTCP commands

This package provide a Common Lisp library for .zip-file reading and writing.

This package provides functions for generating lorem ipsum text.

cl-num-utils implements simple numerical functions for Common Lisp, including:

• num=, a comparison operator for floats

• simple arithmeric functions, like sum and l2norm

• elementwise operations for arrays

• intervals

• special matrices and shorthand for their input

• sample statistics

• Chebyshev polynomials

• univariate rootfinding

This package provides a flexible shallow/deep copy mechanism for Common Lisp.

This package provides a standard way to canonicalize slot values.

This library extracts the TLD (Top Level Domain) from domains. The information is taken from https://publicsuffix.org.

trivial-download allows you to download files from the Internet from Common Lisp. It provides a progress bar.

This is a small library to display a native GUI message box. This can be useful to show error messages and other informational pieces should the application fail and be unable to do so using its standard UI.

The Plump-SEXP library is a backend for Plump which can convert between S-expressions and the Plump DOM.

fast-http is a HTTP request/response protocol parser for Common Lisp.

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.

NClasses provides helper macros to help write classes, conditions, generic functions, and CLOS code in general with less boilerplate.

It's a fork of hu.dwim.defclass-star. It includes some bug fixes and extra features like type inference.

This is a string/octets parser library for Common Lisp with speed and readability in mind. Unlike other libraries, the code is not a pattern-matching-like, but a char-by-char procedural parser.

The cl-data-lens library provides a language for expressing data manipulations as the composition of more primitive operations.

This is a Common Lisp implementation for the Mustache template system. More details on the standard are available at https://mustache.github.io.

This package provides Common Lisp extension to the MOP to allow abstract, final and singleton classes.

This package parses and prints dates in RFC-1123 format.

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.

Dissect is a small Common Lisp library for introspecting the call stack and active restarts.

A utility for running external programs, built on UIOP. Cmd is designed to be natural to use, protect against shell interpolation and be usable from multi-threaded programs.
