Parenscript is a translator from an extended subset of Common Lisp to JavaScript. Parenscript code can run almost identically on both the browser (as JavaScript) and server (as Common Lisp).

Parenscript code is treated the same way as Common Lisp code, making the full power of Lisp macros available for JavaScript. This provides a web development environment that is unmatched in its ability to reduce code duplication and provide advanced meta-programming facilities to web developers.

At the same time, Parenscript is different from almost all other "language X" to JavaScript translators in that it imposes almost no overhead:

• No run-time dependencies: Any piece of Parenscript code is runnable as-is. There are no JavaScript files to include.

• Native types: Parenscript works entirely with native JavaScript data types. There are no new types introduced, and object prototypes are not touched.

• Native calling convention: Any JavaScript code can be called without the need for bindings. Likewise, Parenscript can be used to make efficient, self-contained JavaScript libraries.

• Readable code: Parenscript generates concise, formatted, idiomatic JavaScript code. Identifier names are preserved. This enables seamless debugging in tools like Firebug.

• Efficiency: Parenscript introduces minimal overhead for advanced Common Lisp features. The generated code is almost as fast as hand-written JavaScript.

3D-VECTORS is a library for vector math in 3D space. It contains most of the vector operations one would usually expect out of such a library and offers them both in non-modifying and modifying versions where applicable.

This package provides an implementation of a base 16 builder for Common Lisp.

This package provides Common Lisp bindings to create OpenGL window and context manipulation code as well as system input handling. Direct FFI bindings to system functions are used so no third party C lib is required except system libraries.

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.

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.

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

one-more-re-nightmare is a regular expression engine that uses the technique presented in Regular-expression derivatives re-examined (Owens, Reppy and Turon, 2009; doi:10.1017/S0956796808007090) to interpret and compile regular expressions.

The purpose of this library is to provide a collection of implementations of trees.

In contrast to existing libraries such as cl-containers, it does not impose a particular use for the trees. Instead, it aims for a stratified design, allowing client code to choose between different levels of abstraction.

As a consequence of this policy, low-level interfaces are provided where the concrete representation is exposed, but also high level interfaces where the trees can be used as search trees or as trees that represent sequences of objects.

This is a baseline JPEG codec written in Common Lisp. It can be used for reading and writing JPEG image files.

When dealing with network protocols and file formats, it's common to have to read or write 16-, 32-, or 64-bit datatypes in signed or unsigned flavors. Common Lisp sort of supports this by specifying :element-type for streams, but that facility is underspecified and there's nothing similar for read/write from octet vectors. What most people wind up doing is rolling their own small facility for their particular needs and calling it a day.

This library attempts to be comprehensive and centralize such facilities. Functions to read 16-, 32-, and 64-bit quantities from octet vectors in signed or unsigned flavors are provided; these functions are also SETFable. Since it's sometimes desirable to read/write directly from streams, functions for doing so are also provided. On some implementations, reading/writing IEEE singles/doubles (i.e. single-float and double-float) will also be supported.

cl-jpl-util is a collection of Common Lisp utility functions and macros, primarily for software projects written in CL by the author.

This a Common Lisp library to convert geographic coordinates between latitude/longitude and UTM (Universal Transverse Mercator) or UPS (Universal Polar Stereographic).

The LOCAL-TIME library is a Common Lisp library for the manipulation of dates and times. It is based almost entirely upon Erik Naggum's paper "The Long Painful History of Time".

This package defines a Common Lisp package, :elements, with an ELEMENT structure and a number of functions to search the periodic table.

A miniature toolkit that contains some useful shifting/popping/pushing functions for arrays and vectors. Originally from Plump.

Support library for numcl. Registers a function as an additional form that is considered as a candidate for a constant.

This is a Common Lisp library for processing data found in dBase III database files (dbf and db3 files).

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.

This package provides first-class global environments for Common Lisp.

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.

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 package provides CFFI bindings for Common Lisp to the Cairo C library.

This is a library for quaternions. It contains most of the quaternion operations one would usually expect out of such a library and offers them both in non-modifying and modifying versions where applicable. It also tries to be efficient where plausible. Each quaternion is made up of floats, which by default are single-floats, as they do not require value boxing on most modern systems and compilers.
