Closer to MOP is a compatibility layer that rectifies many of the absent or incorrect CLOS MOP features across a broad range of Common Lisp implementations.

CLAWK is an AWK implementation embedded into Common Lisp.

This package provides some condition classes, functions and macros which may be useful when building slightly complex systems.

This library implements the base58 encoding algorithm. It's basically base64 but with a smaller alphabet (58, as in the name) that doesn't include similar looking characters, among other things. See https://github.com/bitcoin/bitcoin/blob/master/src/base58.h for a full reference.

Pileup is a portable, performant, and thread-safe binary heap for Common Lisp.

Py4CL is a bridge between Common Lisp and Python, which enables Common Lisp to interact with Python code. It uses streams to communicate with a separate python process, the approach taken by cl4py. This is different to the CFFI approach used by burgled-batteries, but has the same goal.

This is an implementation of the Unicode Standards Annex #14 (http://www.unicode.org/reports/tr14/) line breaking algorithm. It provides a fast and convenient way to determine line breaking opportunities in text.

Note that this algorithm does not support break opportunities that require morphological analysis. In order to handle such cases, please consult a system that provides this kind of capability, such as a hyphenation algorithm.

Also note that this system is completely unaware of layouting decisions. Any kind of layouting decisions, such as which breaks to pick, how to space between words, how to handle bidirectionality, and what to do in emergency situations when there are no breaks on an overfull line are left up to the user.

hdf5-cffi is a CFFI wrapper for the HDF5 library.

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.

UBIQUITOUS is a very easy-to-use library for persistent configuration storage. It automatically takes care of finding a suitable place to save your data, and provides simple functions to access and modify the data within.

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 converts the elements from GObject Introspection into Common Lisp-style definitions, based on cl-gobject-introspection.

This is a pure Common Lisp library to create, transform and render anti-aliased vectorial paths.

cl-cron is a simple tool that provides cron like facilities directly inside of Common Lisp.

HTTP-Body parses HTTP POST data and returns POST parameters. It supports application/x-www-form-urlencoded, application/json, and multipart/form-data.

Alternative to the compiler-macro library:

• Here, we do not treat compiler notes as warnings, but instead these are a separate class of conditions. These are also not errors.

• Two main condition classes are provided: compiler-macro-notes:note and compiler-macro-notes:optimization-failure-note. While the latter is a subclass of the former, the latter notes are printed in a slightly different manner to the former.

• To be able to correctly print the expansion path that led to the condition, user code is expected to avoid performing a nonlocal exit to a place outside with-notes.

Portable document preparation system.

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.

cl-gserver is a 'message passing' library / framework with actors similar to Erlang or Akka. It supports creating reactive systems for parallel computing and event based message handling.

This package provides a Common Lisp implementation of the semantic versioning specification: http://semver.org.

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.

System-Load is a Common Lisp library for accessing the system's CPU and memory usage.
