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 library provides a macroexpand-all function that calls the implementation specific equivalent.

This package provides audio input and output functions to Common Lisp using bindings to the portaudio library.

BOOST-LEXER is a tokenizer for Common Lisp that makes heavy use of BOOST-RE.

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.

This package provides Python style generators for Common Lisp. It also includes a port of itertools.

mito-auth provides a mito mixin class for user authorization.

Ningle is a lightweight web application framework for Common Lisp.

This Common Lisp library provides a series data structure much like a sequence, with similar kinds of operations. The difference is that in many situations, operations on series may be composed functionally and yet execute iteratively, without the need to construct intermediate series values explicitly. In this manner, series provide both the clarity of a functional programming style and the efficiency of an iterative programming style.

This package provides a Common Lisp implementation of the semantic versioning specification: http://semver.org.

Schemeish implements several useful Scheme constructs for Common Lisp. These include named-let, define, scheme argument lists, and a shortcut to FUNCALL with [] instead of ().

This package creates GraphViz DOT files from an equivalent s-expression representation.

This is a dead-simple, non validating, inline CSS generator for Common Lisp. Its goals are axiomatic syntax, simple implementation to support portability, and boilerplate reduction in CSS.

Vom is a logging library for Common Lisp. It's goal is to be useful and small. It does not provide a lot of features as other loggers do, but has a small codebase that's easy to understand and use.

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.

The Distributions package provides a collection of probabilistic distributions and related functions

This package provides an extensible implementation of defclass that can accurately control the expansion according to the metaclass and automatically detect the suitable metaclass by analyzing the defclass form.

This library implements efficient algorithms that calculate various string metrics in Common Lisp:

• Damerau-Levenshtein distance

• Hamming distance

• Jaccard similarity coefficient

• Jaro distance

• Jaro-Winkler distance

• Levenshtein distance

• Normalized Damerau-Levenshtein distance

• Normalized Levenshtein distance

• Overlap coefficient

40ants-doc provides a rudimentary explorable programming environment. The narrative primarily lives in so-called sections that mix Markdown docstrings with references to functions, variables, etc., all of which should probably have their own docstrings.

The primary focus is on making code easily explorable by using SLIME's M-. (slime-edit-definition). Generating documentation in Markdown or HTML format from sections and all the referenced items is also implemented.

With the simplistic tools provided, one may obtain results similar to literate programming, but documentation is generated from code, not the other way around, and there is no support for chunking. Code comes first, code must look pretty, documentation is code.

40ants-doc is a fork of MGL-PAX with fewer dependencies (only named-readtables and pythonic-string-reader) for the core system, and additional features in the full system.

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.

This package provides a standard way to canonicalize slot values.

This is a small library providing the ISO-639 language code to language name mapping.

The cl-sqlite package is an interface to the SQLite embedded relational database engine.

This package provides a simple yet powerful value inheritance scheme.
