This package provides a framework to unify arbitrary Common Lisp objects while constructing bindings for placeholders (unification variables) in a template sublanguage.

SQL generator for Common Lisp.

This is a portability library that allows one to fully override the standard debugger provided by their Common Lisp system for situations where binding *debugger-hook* is not enough -- most notably, for break.

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

Implementation of a set-like data structure with constant time addition, removal, and random selection.

qbase64 provides a fast and flexible base64 encoder and decoder for Common Lisp.

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

This is a Common Lisp library for simplifying packaging and loading of compiled foreign library collection.

April compiles a subset of the APL programming language into Common Lisp. Leveraging Lisp's powerful macros and numeric processing faculties, it brings APL's expressive potential to bear for Lisp developers. Replace hundreds of lines of number-crunching code with a single line of APL.

With static-vectors, you can create vectors allocated in static memory.

This package provides an extensible implementation of defclass that can accurately control the expansion according to the metaclass and automatically detect the suitable metaclass by analyzing the defclass form.

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.

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

Very basic library for dealing with CL's hash tables. The idea was spawned through working with enough JSON APIs and config files, causing a lot of headaches in the process.

With static-vectors, you can create vectors allocated in static memory.

3D-MATRICES is a library implementing common matrix operations, mainly intended as the counterpiece to 3d-vectors and thus being aimed at operations in 3D space.

This package provides a Common Lisp wrapper system for the SDL 2.0 C Library.

This package provides a canonical way of converting class designators to classes.

This library implements efficient algorithms that calculate various string metrics in Common Lisp:

• Damerau-Levenshtein distance

• Hamming distance

• Jaccard similarity coefficient

• Jaro distance

• Jaro-Winkler distance

• Levenshtein distance

• Normalized Damerau-Levenshtein distance

• Normalized Levenshtein distance

• Overlap coefficient

This package holds an enhanced implementation of hooks (extension points). It works similarly to Emacs hooks with crucial improvements:

• If the compiler allows it (such as SBCL), type-checking is performed at compile-time and at run-time when adding handlers to a hook.

• On failure, multiple restarts are offered, such as disabling the offending handler or simply continuing to the next function.

• The hook handler execution order and combination can be customized.

• Anonymous functions (lambdas) can be added to hooks as handler objects. When inspecting hooks, readable names are thus exposed instead of lambda blackboxes. Handlers are compared through their names (through the mandatory name slot). A hook can not contain multiple handlers with the same name.

• A special provision is taken for “setters”, handlers that are meant to set a given place to a given values. Such handler objects can be compared and identified uniquely.

This package provides a Common Lisp system implementing event bus.

This a Common Lisp library to convert geographic coordinates between latitude/longitude and MGRS.

This package provides the LOCAL-TIME extensions for the cl-postgres ASDF system of postmodern.

This is a teensy library that provides some functions to determine the mime-type of a file.
