This library provides a modern project skeleton generator. In contract with other generators, CL-Project generates one package per file and encourages unit testing by generating a system for unit testing, so you can begin writing unit tests as soon as the project is generated.

fast-http is a HTTP request/response protocol parser for Common Lisp.

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 package provides a small utility library to open a thing (usually a file or URL) in an appropriate handler (usually an external file manager or browser).

core-gp is a Common Lisp library for genetic programming (GP) algorithms. It allows standard GP, strongly-typed GP, grammatical evolution as well as standard genetic algorithms.

TRIVIAL-TYPES provides missing but important type definitions such as PROPER-LIST, ASSOCIATION-LIST, PROPERTY-LIST and TUPLE.

This library contains code that implements Common Lisp hash tables.

NFiles is a Common Lisp library to help manage file persistence and loading, in particular user-centric files like configuration files. It boasts the following features:

• Dynamic and customizable path expansion.

• Extensible serialization and deserialization.

• Cached reads and writes. When a file object expands to the same path as another one, a read or write on it won’t do anything in case there was no change since last write.

• (Experimental!) On-the-fly PGP encryption.

• Profile support.

• On read error, existing files are backed up.

• On write error, no file is written to disk, the existing file is preserved.

This package provides a PNG Common Lisp system to operate with Portable Network Graphics file format.

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

This library strives to provide a portable TCP/IP and UDP/IP socket interface for as many Common Lisp implementations as possible, while keeping the abstraction and portability layer as thin as possible.

This software provides an interface by which Common Lisp programs can access lexicographic data from WordNet.

CAMBL is a Common Lisp library providing a convenient facility for working with commoditized values. It does not allow compound units (and so is not suited for scientific operations) but does work rather nicely for the purpose of financial calculations.

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

An implementation of the exponential backoff algorithm in Common Lisp. Inspired by the implementation found in Chromium. Read the header file to learn about each of the parameters.

This package provides a way of extracting and replicating the compile-time side-effects of forms.

CHRONICITY is Common Lisp natural language date and time parser inspired by Ruby's Chronic.

EXTERNAL-PROGRAM enables running programs outside the Lisp process. It is an attempt to make the RUN-PROGRAM functionality in implementations like SBCL and CCL as portable as possible without sacrificing much in the way of power.

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 package provides an embedded template engine for Common Lisp.

This is a collection of useful helper modules and standard implementations for Radiance interfaces.

Alternative to the compiler-macro library:

• Here, we do not treat compiler notes as warnings, but instead these are a separate class of conditions. These are also not errors.

• Two main condition classes are provided: compiler-macro-notes:note and compiler-macro-notes:optimization-failure-note. While the latter is a subclass of the former, the latter notes are printed in a slightly different manner to the former.

• To be able to correctly print the expansion path that led to the condition, user code is expected to avoid performing a nonlocal exit to a place outside with-notes.

with-user-abort is a Common Lisp portability library providing a like-named macro that catches the SIGINT signal.

Inquisitor is a cross-implementation library providing encoding/end-of-line detection and external-format abstraction for Common Lisp.
