PARSE is a simple token parsing library for Common Lisp.

Transducers are an ergonomic and extremely memory-efficient way to process a data source. Data source refers to simple collections like lists or vectors, but also potentially large files or generators of infinite data.

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.

This package provides a Common Lisp translation library similar to CL-I18N and CL-L10N.

Max’s Parser Combinators is a simple and pragmatic library for writing parsers and lexers based on combinatory parsing. MaxPC is capable of parsing deterministic, context-free languages, provides powerful tools for parse tree transformation and error handling, and can operate on sequences and streams. It supports unlimited backtracking, but does not implement Packrat Parsing. Instead, MaxPC achieves good performance through its optimized primitives, and explicit separation of matching and capturing input. In practice, MaxPC parsers perform better on typical computer languages—when compared to Packrat parsers—at the expense of not producing linear-time parsers.

CL-LOG is a general purpose logging utility, loosely modelled in some respects after Gary King's Log5. Its features include: logging to several destinations at once, via "messengers", each messenger is tailored to accept some log messages and reject others, and this tailoring can be changed on-the-fly, very rapid processing of messages which are rejected by all messengers, fully independent use of the utility by several different sub-systems in an application, support for messengers which cl:format text to a stream, support for messengers which do not invoke cl:format, timestamps in theory accurate to internal-time-units-per-second.

cl-mssql provides an interface to connect to Microsoft SQL server. It uses the libsybdb foreign library provided by the FreeTDS project.

ST-JSON (ST because it originated at Streamtech) is a Common Lisp library for encoding and decoding JSON values (as specified on json.org).

This library does mostly the same thing as CL-JSON, but is simpler and more precise about types (distinguishing boolean false, the empty array, and the empty object).

This library provides low-level libuv bindings for Common Lisp.

Gray streams is an interface proposed for inclusion with ANSI CL by David N. Gray. The proposal did not make it into ANSI CL, but most popular CL implementations implement it. This package provides an extremely thin compatibility layer for gray streams.

CL-DATA-STRUCTURES is a Common Lisp library providing a portable collection of mutable and immutable data structures (dictionaries, sets, queues, sequences) and algorithms.

dbi is a Common Lisp library providing a database independent interface for MySQL, PostgreSQL and SQLite.

Nodgui (No Drama GUI) is a Common Lisp binding for the Tk GUI toolkit. It also provides a few additional widgets more than the standard Tk ones.

This library allows creation of hash tables with arbitrary test/hash functions, in addition to the test functions allowed by the standard (EQ, EQL, EQUAL and EQUALP), even in implementations that don't support this functionality directly.

The GTWIWTG library (Generators The Way I Want Them Generated -- technically not generators, but iterators) is meant to be small, explorable, and understandable.

generic-cl provides a generic function wrapper over various functions in the Common Lisp standard, such as equality predicates and sequence operations. The goal of this wrapper is to provide a standard interface to common operations, such as testing for the equality of two objects, which is extensible to user-defined types.

Aims to be fast, modular, cachable and concise. It does so by defining each tag as a macro which expands to code printing the respective HTML source. Also employs a DSL for element attributes.

Supertrace provides a superior Common Lisp trace functionality for debugging and profiling real world applications.

This library exports three symbols: with-raw-io, read-char, and read-line, to provide raw POSIX I/O in Common Lisp.

Opticl is a Common Lisp library for representing, processing, loading, and saving 2-dimensional pixel-based images.

This package provides a Common Lisp library to work with the JSON file format.

This package provides prototype Common Lisp implementations of TLS, RFC5246, ASN.1, x501,509, and PKCS1,3,5,8.

This package provides a Common Lisp parser for glTF file format.
