trivial-garbage provides a portable API to finalizers, weak hash-tables and weak pointers on all major implementations of the Common Lisp programming language.

CF is a Common Lisp library for doing computations using continued fractions.

Ironclad is a cryptography library written entirely in Common Lisp. It includes support for several popular ciphers, digests, MACs and public key cryptography algorithms. For several implementations that support Gray streams, support is included for convenient stream wrappers.

Varjo is a Lisp to GLSL compiler. Vari is the dialect of lisp Varjo compiles. It aims to be as close to Common Lisp as possible, but naturally it is statically typed so there are differences.

Parseq (pronounced parsec) is a parsing library for common lisp. It can be used for parsing lisp's sequences types: strings, vectors (e.g. binary data) and lists. Furthermore, parseq is able to parse nested structures such as trees (e.g. lists of lists, lists of vectors, vectors of strings).

Parseq uses parsing expression grammars (PEG) that can be defined through a simple interface. Extensions to the standard parsing expressions are available. Parsing expressions can be parameterised and made context aware. Additionally, the definition of each parsing expression allows the arbitrary transformation of the parsing tree.

The library is inspired by Esrap and uses a very similar interface. No code is shared between the two projects, however. The features of Esrap are are mostly included in parseq and complemented with additional, orthogonal features. Any resemblance to esrap-liquid is merely coincidental.

This Common Lisp library interprets escape characters the same way that most other programming language do. It provides four readtables. The default one lets you write strings like this: #"This string has a newline in it!".

Clip is an attempt at a templating library that allows you to write templates in a way that is both accessible to direct webdesign and flexible. The main idea is to incorporate transformation commands into an HTML file through tags and attributes. Clip is heavily dependent on Plump and lQuery.

This package provides a Common Lisp library for manipulating graphs and running graph algorithms.

Eclector is a portable Common Lisp reader that is highly customizable, can recover from errors and can return concrete syntax trees.

In contrast to many other reader implementations, eclector can recover from most errors in the input supplied to it and continue reading. This capability is realized as a restart.

It can also produce instances of the concrete syntax tree classes provided by the concrete syntax tree library.

This package provides a hierarchy of major functions and auxiliary functions related to the structured analysis and processing of open text.

doplus is an iteration macro 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.

This a Common Lisp library for reading and writing binary data. It is based on code from chapter 24 of the book Practical Common Lisp.

Pileup is a portable, performant, and thread-safe binary heap for Common Lisp.

atomichron is a Common Lisp library which implements a time meter which tracks how many times a form is evaluated, and how long evaluation takes. It uses atomic instructions so that meters will present correct results in the presence of multiple threads, while trying to minimize synchronization latency.

MAP-BIND is a macro that allows visual grouping of variables with their corresponding values in calls to mapping operators when using an inline LAMBDA.

This is a library for reading semi-raw user input from terminals. Semi-raw as in, we can't detect if the user pressed the Control key alone, and the function keys are a mystery. What is supported, however, is:

• Regular characters

• Control+[key]

• Alt+[key]

• Control+Alt+[key]

This library implements various functions to access status information about the machine, process, etc.

This package provides a stream based JSON parser/writer, well suited as building block for higher level libraries.

Cl-tga was written to facilitate loading .tga files into OpenGL programs. It's a very simple library, and, at the moment, only supports non-RLE encoded forms of the files.

This package provides an example implementation of the Common Lisp condition system and library, based on the original condition system implementation by Kent M. Pitman.

This package provides Common Lisp support for reading the Terragen .TER format. The format specification can be found at https://planetside.co.uk/wiki/index.php?title=Terragen_.TER_Format

Domain specific language for producing TeX documents with Common Lisp.

3D-VECTORS is a library for vector math in 3D space. It contains most of the vector operations one would usually expect out of such a library and offers them both in non-modifying and modifying versions where applicable.
