This is a very simple color library for Common Lisp, providing:

• Types for representing colors in HSV, HSL, and RGB spaces.

• Simple conversion functions between the above types.

• Function printing colors to HEX, RGB, RGBA, and HSL.

• Predefined colors from X11, SVG, and GDK.

This package provides a trivial line-input library for VT-like terminals.

This library features a rectangle packer for sprite and texture atlases.

generic-cl provides a generic function wrapper over various functions in the Common Lisp standard, such as equality predicates and sequence operations. The goal of this wrapper is to provide a standard interface to common operations, such as testing for the equality of two objects, which is extensible to user-defined types.

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.

This is a Common Lisp library providing a set of macros for generating lexical analyzers automatically. The lexers generated using cl-lex can be used with cl-yacc.

This is a Common Lisp library for reading PNG images.

HELambdap is a Common Lisp documentation system which strives to be simple to use, yet easily customizable.

This package provides GNU gettext completely implemented in Common Lisp without any C library bindings.

This package provides an implementation of the Matrix API for Common Lisp.

Prometheus.io Common Lisp client.

This is a Common Lisp library for creating PNG images.

This Common Lisp library provides utilities for the Bodge library collection.

The server part of AllegroServe can be used either as a standalone web server or a module loaded into an application to provide a user interface to the application. AllegroServe's proxy ability allows it to run on the gateway machine between some internal network and the Internet. AllegroServe's client functions allow Lisp programs to explore the web.

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

This library simplifies functional programming in Common Lisp by making it easier to make new data structures with specified changes in place.

This package provides a DSL for array slices in Common Lisp.

Random-Sample is a library for reliably taking a random sample from a sequence.

Common Lisp ships with a set of powerful built in data structures including the venerable list, full featured arrays, and hash-tables. CL-containers enhances and builds on these structures by adding containers that are not available in native Lisp (for example: binary search trees, red-black trees, sparse arrays and so on), and by providing a standard interface so that they are simpler to use and so that changing design decisions becomes significantly easier.

This is a library to provide cross-platform access to gamepads, joysticks, and other such HID devices.

In the crowded space of Common Lisp HTML generators, Spinneret occupies the following coordinates:

• Modern. Targets HTML5. Does not treat XML and HTML as the same problem. Assumes you will be serving your documents as UTF-8.

• Composable. Makes it easy to refactor HTML generation into separate functions and macros.

• Pretty. Treats HTML as a document format, not a serialization. Output is idiomatic and readable, following the coding style of the HTML5 specification.

• Aggressive. If something can be interpreted as HTML, then it will be, meaning that some Lisp forms can't be mixed with HTML syntax. In the trade-off between 90% convenience and 10% correctness Spinneret is on the side of convenience.

• Bilingual. Spinneret (after loading spinneret/ps) has the same semantics in Lisp and Parenscript.

This is a YAML parser and emitter for Common Lisp built on top of libyaml.

This project is intended as a catchall for small, general-purpose extensions to Common Lisp. It contains:

• new-let, a macro that combines and generalizes let, let* and multiple-value-bind,

• gmap, an iteration macro that generalizes map.

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