This Common Lisp library provides reader macros for concise expression of function partial application and composition.

cl-strings is a small, portable, dependency-free set of utilities that make it even easier to manipulate text in Common Lisp. It has 100% test coverage and works at least on sbcl, ecl, ccl, abcl and clisp.

PP-TOML is a Common Lisp library for parsing strings in the TOML configuration file format. It implements only the 0.1.0 specification of TOML.

This is a Common Lisp logging framework that can log at various levels and mix text with expressions.

This Common Lisp package offers an implementation of the 32-bit variant of MurmurHash3 (https://github.com/aappleby/smhasher), a fast non-crytographic hashing algorithm.

Portability library for IEEE float features that are not covered by the Common Lisp standard.

This package provides CIEL as a precompiled binary and a full-featured REPL for the terminal.

Common Lisp library for channel-based concurrency. In a nutshell, you create various threads sequentially executing tasks you need done, and use channel objects to communicate and synchronize the state of these threads.

The Bordeaux-FFT library provides a reasonably efficient implementation of the Fast Fourier Transform and its inverse for complex-valued inputs, in portable Common Lisp.

Antik provides a foundation for scientific and engineering computation in Common Lisp. It is designed not only to facilitate numerical computations, but to permit the use of numerical computation libraries and the interchange of data and procedures, whether foreign (non-Lisp) or Lisp libraries. It is named after the Antikythera mechanism, one of the oldest examples of a scientific computer known.

bubble-operator-upwards is a function that bubbles an operator upwards in a form, demultiplexing all alternative branches by way of cartesian product.

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

Radiance is a web application environment, which is sort of like a web framework, but more general, more flexible. It should let you write personal websites and generally deployable applications easily and in such a way that they can be used on practically any setup without having to undergo special adaptations.

postmodern is a Common Lisp library for interacting with PostgreSQL databases. It provides the following features:

• Efficient communication with the database server without need for foreign libraries.

• Support for UTF-8 on Unicode-aware Lisp implementations.

• A syntax for mixing SQL and Lisp code.

• Convenient support for prepared statements and stored procedures.

• A metaclass for simple database-access objects.

This package produces 4 systems: postmodern, cl-postgres, s-sql, simple-date

SIMPLE-DATE is a very basic implementation of date and time objects, used to support storing and retrieving time-related SQL types. It is not loaded by default and you can use local-time (which has support for timezones) instead.

S-SQL is used to compile s-expressions to strings of SQL code, escaping any Lisp values inside, and doing as much as possible of the work at compile time.

CL-POSTGRES is the low-level library used for interfacing with a PostgreSQL server over a socket.

POSTMODERN itself is a wrapper around these packages and provides higher level functions, a very simple data access object that can be mapped directly to database tables and some convenient utilities. It then tries to put all these things together into a convenient programming interface

With lispy syntax, shortcuts, and improvements, LASS aims to help you out in writing CSS quick and easy. LASS was largely inspired by SASS. LASS supports two modes, one being directly in your lisp code, the other in pure LASS files.

Common Lisp comes with quite some functions to compare objects for equality, yet none is applicable in every situation and in general this is hard, as equality of objects depends on the semantics of operations on them. As consequence, users find themselves regularly in a situation where they have to roll their own specialized equality test.

This module provides one of many possible equivalence relations between standard Common Lisp objects. However, it can be extended for new objects through a simple CLOS protocol. The rules when two objects are considered equivalent distinguish between mutating and frozen objects. A frozen object is promised not to be mutated in the future in a way that operations on it can notice the difference.

We have chosen to compare mutating objects only for identity (pointer equality), to avoid various problems. Equivalence for frozen objects on the other hand is established by recursing on the objects' constituent parts and checking their equivalence. Hence, two objects are equivalent under the OBJECT= relation, if they are either identical, or if they are frozen and structurally equivalent, i.e. their constituents are point-wise equivalent.

Since many objects are potentially mutable, but are not necessarily mutated from a certain point in their life time on, it is possible to promise to the equivalence relation that they remain frozen for the rest of their life time, thus enabling coarser equivalence than the often too fine-grained pointer equality.

CL-DOT is a Common Lisp library for generating Graphviz dot output from arbitrary Lisp data.

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.

This library enable rapid file search, inspection and manipulation straight from the REPL. It aims at replacing Unix tools such as find or du. It also offers a replacement to the pathname Common Lisp API. Slot writers which commit changes to disk, e.g. permissions, modification time, etc.

This is a coroutine library for Common Lisp implemented using the continuations of the cl-cont library.
