definitions-systems provides a simple unified extensible way of processing named definitions.

This is a library to allow easy handling of external processes, and primarily to get their output. It handles proper copying of the standard and error outputs of the process simultaneously, both in a sequential and parallel fashion. It also features a lazy directory switching mechanism, to avoid running into parallelism problems when having to change directory.

This lisp library handles physical quantities which consist of

• value / magnitude

• uncertainty / error

• unit

where the type of the value can be any subtype of real. For the uncertainty, both absolute and relative values are possible. Combinations of lisp symbols or strings are used to describe units. User defined units including abbreviations and prefixes are supported. Error propagation and unit checking is performed for all defined operations.

This package provides KONS-9 which can be considered as a traditional user interface driven 3D application for general artists, or as a REPL-based development environment for technical artists and software developers. These two approaches can be seamlessly combined into a flexible and powerful workflow, where non-technical users can immediately benefit from software tools and extensions developed by technical users.

CLOBBER is an alternative to so-called object prevalence, and in particular to cl-prevalence. Clobber is both simpler, more flexible, and more robust than systems based on object prevalence.

cl-random is a library for generating random draws from various commonly used distributions, and for calculating statistical functions, such as density, distribution and quantiles for these distributions.

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

This package provides Common Lisp FFI bindings for xkbcommon (libxkbcommon) using cffi-grovel.

STMX is a high-performance implementation of composable Transactional Memory, which is a concurrency control mechanism aimed at making concurrent programming easier to write and understand. Instead of traditional lock-based programming, one programs with atomic memory transactions, which can be composed together to make larger atomic memory transactions.

A memory transaction gets committed if it returns normally, while it gets rolled back if it signals an error (and the error is propagated to the caller).

Finally, memory transactions can safely run in parallel in different threads, are re-executed from the beginning in case of conflicts or if consistent reads cannot be guaranteed, and their effects are not visible from other threads until they commit.

Memory transactions give freedom from deadlocks, are immune to thread-safety bugs and race conditions, provide automatic roll-back on failure, and aim at resolving the tension between granularity and concurrency.

This is a Common Lisp macro for defining temporary caches that invalidate based on expressions evaluating to different values.

(X)HTMLambda is yet another (X)HTML library which emphasizes programmability and user-friendliness. Each (X)HTML element is a structured object and pretty-printing of (X)HTML trees is well defined to provide properly indented human-readable output even for complex recursive arrangements.

This is a library to find system font files. It works on systems with FontConfig on Linux, BSD. It does not have any foreign dependencies that aren't already directly available on the system.

This package provides a PEM (Privacy-Enhanced Mail) parser for Common Lisp.

Wu-Decimal enables convenient, arbitrary-precision decimal arithmetic through a reader macro, #$, and an update to the pprint dispatch table. Wu-Decimal uses the CL rational type to store decimals, which enables numeric functions such as +, -, etc., to operate on decimal numbers in a natural way.

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.

BOOST-PARSE is a simple token parsing library for Common Lisp.

Trivial Monitored Thread offers a very simple (aka trivial) way of spawning threads and being informed when one any of them crash and die.

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.

This library can be used to print the licenses used by a Common Lisp project and its dependencies.

HTML parser/emitter for CommonDoc.

3D-MATRICES is a library implementing common matrix operations, mainly intended as the counterpiece to 3d-vectors and thus being aimed at operations in 3D space.
