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

CL-UNICODE is a portable Unicode library Common Lisp, which is compatible with perl. It is pretty fast, thread-safe, and compatible with ANSI-compliant Common Lisp implementations.

Mito is yet another object relational mapper, and it aims to be a successor of Integral.

• Support MySQL, PostgreSQL and SQLite3.

• Add id (serial/uuid primary key), created_at and updated_at by default like Ruby's ActiveRecord.

• Migrations.

• Database schema versioning.

FSet is a functional set-theoretic collections library for Common Lisp. Functional means that all update operations return a new collection rather than modifying an existing one in place. Set-theoretic means that collections may be nested arbitrarily with no additional programmer effort; for instance, sets may contain sets, maps may be keyed by sets, etc.

This is a very simple implementation of SHA1 and HMAC-SHA1 for Common Lisp. The code is intended to be easy to follow and is therefore a little slower than it could be.

This is a websocket server for Common Lisp using usockets to be portable between implementations and operating systems. It has a programming interface that allows for multiple websocket apps per server using Common Lisp keywords for different websocket events. It has useful restarts and customizable errors.

cl-cookie is a Common Lisp library featuring parsing of cookie headers, cookie creation, cookie jar creation and more.

This is a Common Lisp library for reading PNG images.

CL-Ledger is a Common Lisp port of the Ledger double-entry accounting system.

This library implements the -> and ->> macros from Clojure, as well as several expansions on the idea.

Plump is a parser for HTML/XML-like documents, focusing on being lenient towards invalid markup. It can handle things like invalid attributes, bad closing tag order, unencoded entities, inexistent tag types, self-closing tags and so on. It parses documents to a class representation and offers a small set of DOM functions to manipulate it. It can be extended to parse to your own classes.

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.

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

Chunga implements streams capable of chunked encoding on demand as defined in RFC 2616.

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

CL-DOT is a Common Lisp library for generating Graphviz dot output from arbitrary Lisp data.

This package provides Common Lisp bindings to the pango text layout library.

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

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.

CL-PDF is a cross-platform Common Lisp library for generating PDF files.

CL-STRFTIME is a Common Lisp compiler for the strftime “language.”

Cluffer is a library for representing the buffer of a text editor. As such, it defines a set of CLOS protocols for client code to interact with the buffer contents in various ways, and it supplies different implementations of those protocols for different purposes.

In the crowded space of Common Lisp HTML generators, Spinneret occupies the following coordinates:

• Modern. Targets HTML5. Does not treat XML and HTML as the same problem. Assumes you will be serving your documents as UTF-8.

• Composable. Makes it easy to refactor HTML generation into separate functions and macros.

• Pretty. Treats HTML as a document format, not a serialization. Output is idiomatic and readable, following the coding style of the HTML5 specification.

• Aggressive. If something can be interpreted as HTML, then it will be, meaning that some Lisp forms can't be mixed with HTML syntax. In the trade-off between 90% convenience and 10% correctness Spinneret is on the side of convenience.

• Bilingual. Spinneret (after loading spinneret/ps) has the same semantics in Lisp and Parenscript.

Trivia is a pattern matching compiler that is compatible with Optima, another pattern matching library for Common Lisp. It is meant to be faster and more extensible than Optima.
