This is a reverse proxy server written in and configurable in Common Lisp. It supports WebSocket, HTTP, HTTPS, HTTP to HTTPS redirecting, port and host forwarding configuration using a real programming language, HTTP header and body manipulation (also using a real programming language).

Utility library for handling bit vectors, bit vector arithmetic, and universal integer type conversions between bit-vectors, byte-vectors, octals, decimals, and hexadecimal notation.

This library provides a WebSockets extension for the Huchentoot web server.

This library contains generic hacks meant to be used in any project. It was originally developed for the Cells library.

Filtered functions provide an extension of CLOS generic function invocation that add a simple preprocessing step before the actual method dispatch is performed and thus enable the use of arbitrary predicates for selecting and applying methods. See http://www.p-cos.net/documents/filtered-dispatch.pdf for a paper that introduces and explains filtered functions in detail.

This library is an SDL wrapper as part of an umbrella project that provides cross-platform packages for building large, interactive applications in Common Lisp.

This package provides a JSON Pointer (RFC6901) implementation for Common Lisp. This library aims to be independent from any JSON libraries (as much as possible).

This package provides a Common Lisp implementation of Base64 encoding and decoding. Base64 encoding is a technique to encode binary data in a portable, safe printable, 7-bit ASCII format.

Html-entities is a Common Lisp library that lets you encode and decode entities in HTML.

This package is a list manipulation library for Common Lisp inspired by Haskell package Data.List.

doplus is an iteration macro for Common Lisp.

clingon is a command-line option parsing library for Common Lisp. Its features include:

• Support for subcommands

• Support for command aliases

• Support for short and long options

• Related options may be grouped into categories

• Short options may be collapsed into a single argument, as in -xyz

• Long options support the notations --long-opt arg and --long-opt=arg

• Automatic generation of help/usage information for commands and subcommands

• Out-of-the-box support for --version and --help

• Support for various kinds of options including string, integer, boolean, switch, enum, list, counter, filepath, etc.

• Subcommands can look up global options defined in parent commands

• Support for required options

• Options can be initialized via environment variables

• Single interface for creating options using CLINGON:MAKE-OPTION

• Generate documentation for your command-line application

• Support for pre-hook and post-hook actions for commands, which allow invoking functions before and after the respective handler of the command is executed

• Support for Bash and Zsh completions

• Extensibility, so if you don't find something you need you can extend it by developing a new option kind, or even a new mechanism for initializing options, e.g., by looking up an external key/value store

ASDF-FLV provides support for file-local variables through ASDF. A file-local variable behaves like *PACKAGE* and *READTABLE* with respect to LOAD and COMPILE-FILE: a new dynamic binding is created before processing the file, so that any modification to the variable becomes essentially file-local.

In order to make one or several variables file-local, use the macros SET-FILE-LOCAL-VARIABLE(S).

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.

This package ensures that special subclasses of standard-object cluster right in front of standard-object in the class precedence list.

DEFPACKAGE-PLUS is an extensible DEFPACKAGE variant with predictable cross-platform behavior and some utilities useful for versioning.

defclass-star provides defclass* and defcondition* to simplify class and condition declarations. Features include:

• Automatically export all or select slots at compile time.

• Define the :initarg and :accessor automatically.

• Specify a name transformer for both the :initarg and :accessor, etc.

• Specify the :initform as second slot value.

See https://common-lisp.net/project/defclass-star/configuration.lisp.html for an example.

UFFI provides a universal foreign function interface (FFI) for Common Lisp.

One of the many things that didn't quite get into the Common Lisp standard was how to get a Lisp to output its call stack when something has gone wrong. As such, each Lisp has developed its own notion of what to display, how to display it, and what sort of arguments can be used to customize it. trivial-backtrace is a simple solution to generating a backtrace portably.

Command-Line-Args provides a main macro (command) that wraps a defun form and creates a new function that parses the command line arguments. It has support for command-line options, positional, and variadic arguments. It also generates a basic help message. The interface is meant to be easy and non-intrusive.

cl-dotenv is a utility library for loading .env files in Common Lisp.

This is a Common Lisp library providing a unified way to work with package locks across supported Common Lisp implementations.

This library can be used to display a progress bar on one line.

Radiance is a web application environment, which is sort of like a web framework, but more general, more flexible. It should let you write personal websites and generally deployable applications easily and in such a way that they can be used on practically any setup without having to undergo special adaptations.
