CMN provides a package of functions to hierarchically describe a musical score. When evaluated, the musical score is rendered to an image.

A Common Lisp library for computing differences between sequences based on the Python difflib module.

This package provides tools for manipulating data in files using data frames.

Library to fuzzily parse time and date strings into a universal-time timestamp.

CLSS is a DOM traversal engine based on CSS selectors. It makes use of the Plump-DOM and is used by lQuery.

OpenAPI client system generator.

This library is a redefinition of the standard Common Lisp package that includes a number of renames and shadows.

This is a common lisp library to easily pluralize and singularize English and Portuguese words. This is a port of the ruby ActiveSupport Inflector module.

ISSR core provides functions and variables for ISSR server modules so that different servers can behave similarly. The most important features are Document Object Model differencing to generate instructions to update a DOM, and DOM cleaning, to ensure that all remote DOMs are the same.

This Common Lisp package provides a regular expression engine.

This library provides a WebSockets extension for the Huchentoot web server.

It's very basic implementation of channels and queue for Common Lisp.

Flute is an easily composable HTML5 generation library in Common Lisp.

This piece of code sets up some reader macros that make it simpler to input string literals which contain backslashes and double quotes This is very useful for writing complicated docstrings and, as it turns out, writing code that contains string literals that contain code themselves.

This is a terminfo database front end in Common Lisp. The package provides a method for determining which capabilities a terminal (e.g. "xterm") has and methods to compile or put commands to a stream.

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.

IOlib is to be a better and more modern I/O library than the standard Common Lisp library. It contains a socket library, a DNS resolver, an I/O multiplexer(which supports select(2), epoll(4) and kqueue(2)), a pathname library and file-system utilities.

Eazy-Gnuplot is a Common Lisp interface to gnuplot which eschews CFFI, CLOS and structures. It communicates with gnuplot via *standard-output*, and users can plot data by printing to that stream.

This library provides purely functional dictionaries and sets in Common Lisp based on the hash array-mapped trie data structure.

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 Common Lisp library provides utilities for the Bodge library collection.

This library implements the let+ macro, which is a dectructuring extension of let*. It features:

• Clean, consistent syntax and small implementation (less than 300 LOC, not counting tests)

• Placeholder macros allow editor hints and syntax highlighting

• &ign for ignored values (in forms where that makes sense)

• Very easy to extend

Nsymbols extends the regular package API of ANSI CL with more operations, allowing one to list:

• package-symbols.

• package-variables.

• package-functions.

• package-generic-functions.

• package-macros.

• package-classes.

• package-structures.

• And other symbol types, given define-symbol-type for those.

Nsymbols can also find symbols by their name/matching symbol with resolve-symbol. All these operations are aware of symbol visibility in the given packages, due to a symbol-visibility function.

An additional nsymbols/star system has a set of functions mirroring the regular Nsymbols ones, but using closer-mop to provide better results and returning structured data instead of symbols.

cl-xkb is a Common Lisp wrapper for the libxkbcommon keyboard handling library.

The library currently supports these xkb modules:

• Keysyms

• Library Context

• Include Paths

• Logging Handling

• Keymap Creation

• Keymap Components

• Keyboard State

• Compose and dead-keys support
