CL-INTERPOL is a library for Common Lisp which modifies the reader so that you can have interpolation within strings similar to Perl or Unix Shell scripts. It also provides various ways to insert arbitrary characters into literal strings even if your editor/IDE doesn't support them.

POLICY-COND provides tools to insert and execute code based on a compiler's OPTIMIZE policy. It also contains a contract-like notion of expectations, which allow dynamic checking or inclusion of various things that should happen depending on compiler policy.

Coalton is a dialect of ML embedded in Common Lisp. It emphasizes practicality and interoperability with Lisp, and is intended to be a DSL that allows one to gradually make their programs safer.

The Plump-SEXP library is a backend for Plump which can convert between S-expressions and the Plump DOM.

F2cl is a Common Lisp library that can convert Fortran 77 code into Common Lisp code.

This package provides support routines for the claw Common Lisp package.

This package provides an ANSI CL adaptation of the SBCL mailbox utility.

CL-DISKSPACE is a Common Lisp library to list disks with the command line tool df and get disk space information using statvfs.

Cl-reexport makes a package reexport symbols which are external symbols in other Common Lisp packages. This functionality is intended to be used with (virtual) hierarchical packages.

This is an extension to MODULARIZE that allows your application to define interfaces in-code that serve both as a primary documentation and as compliance control.

cl-css-lite is a library for generating CSS from an s-exp based syntax. When compiled with Parenscript loaded in the Lisp image, it also provides the same CSS generation facilities in Parenscript-generated JavaScript code.

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

This library provides all of

• ad hoc polymorphism and

• subtype polymorphism

• parametric polymorphism (in a very limited sense)

to dispatch on the basis of types rather than classes.

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

This is a reverse proxy server written in and configurable in Common Lisp. It supports WebSocket, HTTP, HTTPS, HTTP to HTTPS redirecting, port and host forwarding configuration using a real programming language, HTTP header and body manipulation (also using a real programming language).

cl-transmission is a library to interface with the Transmission torrent client using its RPC (remote procedure call).

This is a string/octets parser library for Common Lisp with speed and readability in mind. Unlike other libraries, the code is not a pattern-matching-like, but a char-by-char procedural parser.

Parse-Declarations is a Common Lisp library to help writing macros which establish bindings. To be semantically correct, such macros must take user declarations into account, as these may affect the bindings they establish. Yet the ANSI standard of Common Lisp does not provide any operators to work with declarations in a convenient, high-level way. This library provides such operators.

Hunchentoot is a web server written in Common Lisp and at the same time a toolkit for building dynamic websites. As a stand-alone web server, Hunchentoot is capable of HTTP/1.1 chunking (both directions), persistent connections (keep-alive), and SSL.

This is a Common Lisp library that converts floating point values to IEEE 754 binary representation.

Screamer is an extension of Common Lisp that adds support for nondeterministic programming. Screamer consists of two levels. The basic nondeterministic level adds support for backtracking and undoable side effects. On top of this nondeterministic substrate, Screamer provides a comprehensive constraint programming language in which one can formulate and solve mixed systems of numeric and symbolic constraints. Together, these two levels augment Common Lisp with practically all of the functionality of both Prolog and constraint logic programming languages such as CHiP and CLP(R). Furthermore, Screamer is fully integrated with Common Lisp. Screamer programs can coexist and interoperate with other extensions to as CLIM and Iterate.

This library is an implementation of Deflate (RFC 1951) decompression, with optional support for ZLIB-style (RFC 1950) and gzip-style (RFC 1952) wrappers of deflate streams. It currently does not handle compression.

This package provides a compute-effective-slot-definition-initargs generic function that allows for more ergonomic initialization of effective slot definition objects.

CL-HEAP provides various implementations of heap data structures (a binary heap and a Fibonacci heap) as well as an efficient priority queue.
