This is a utility library providing access to the mmap family of functions in a portable way. It allows you to directly map a file into the address space of your process without having to manually read it into memory sequentially. Typically this is much more efficient for files that are larger than a few Kb.

HTML parser/emitter for CommonDoc.

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.

Trivial Monitored Thread offers a very simple (aka trivial) way of spawning threads and being informed when one any of them crash and die.

cl-random is a library for generating random draws from various commonly used distributions, and for calculating statistical functions, such as density, distribution and quantiles for these distributions.

Flexi-streams is an implementation of "virtual" bivalent streams that can be layered atop real binary or bivalent streams and that can be used to read and write character data in various single- or multi-octet encodings which can be changed on the fly. It also supplies in-memory binary streams which are similar to string streams.

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

CL-DATA-STRUCTURES is a Common Lisp library providing a portable collection of mutable and immutable data structures (dictionaries, sets, queues, sequences) and algorithms.

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

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

The Bordeaux-FFT library provides a reasonably efficient implementation of the Fast Fourier Transform and its inverse for complex-valued inputs, in portable Common Lisp.

This library provides a wrapper type for secret values, to reduce the risk of accidentally revealing them.

This library is a portable compatibility layer around package local nicknames (PLN). This was done so there is a portability library for the PLN API not included in DEFPACKAGE.

Dynamic-mixins is for simple, dynamic class combination; it allows objects to be mixed and updated without manually defining many permutations.

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.

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

Named readtables is a library that creates a namespace for named readtables, which is akin to package namespacing in Common Lisp.

This library is an extension of the Common Lisp Object System (CLOS) that allows a compiler to inline a generic function under certain conditions.

cl-syslog is a Common Lisp library that provides access to the syslog logging facility.

This package provides a canonical way of converting generalized booleans to booleans.

This is a simple extension to MODULARIZE that allows modules to define and trigger hooks, which other modules can hook on to.

This package provides a Common Lisp implementation of ActivityPub and ActivityStreams standards for social networking.

Features:

• Parsing and un-parsing ActivityStreams JSON-LD objects to/from CLOS objects with convenient accessors on those.

• Sending and fetching ActivityStreams objects to/from the ActivityStreams-enabled HTTP(S) URLs.

• Semantic info extraction with methods like name*, url*, author*, and published*.

• No reliance on JSON parser. njson is used for parser-independent JSON handling. Load the parser backend you prefer!

The py-configparser package implements the ConfigParser Python module functionality in Common Lisp. In short, it implements reading and writing of .INI-file style configuration files with sections containing key/value pairs of configuration options. In line with the functionalities in the python module, does this package implement basic interpolation of option values in other options.
