The main purpose of this n+2nd reimplementation of quasiquote is enable matching of quasiquoted patterns, using Optima or Trivia.

Prometheus.io Common Lisp client.

Splits sequence into a list of subsequences delimited by objects satisfying the test.

Cl-reexport makes a package reexport symbols which are external symbols in other Common Lisp packages. This functionality is intended to be used with (virtual) hierarchical packages.

This is a packrat parser for Common Lisp. In addition to regular Packrat / Parsing Grammar / TDPL features ESRAP supports:

• dynamic redefinition of nonterminals

• inline grammars

• semantic predicates

• introspective facilities (describing grammars, tracing, setting breaks)

• left-recursive grammars

• functions as terminals

• accurate, customizable parse error reports

The Babel library solves a similar problem while understanding more encodings. Trivial UTF-8 was written before Babel existed, but for new projects you might be better off going with Babel. The one plus that Trivial UTF-8 has is that it doesn't depend on any other libraries.

This library contains generic hacks meant to be used in any project. It was originally developed for the Cells library.

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

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

Coleslaw is a static site generator written in Common Lisp.

This package provides an enhanced version of typep that is exactly like the one in the Lisp spec, except it can also accept a single type argument, in which case it returns the appropriate closure.

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

Generic documentation builder for Common Lisp projects.

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.

cl-mysql is a Common Lisp implementation of a MySQL wrapper.

This package provides a client for SMTP.

This is a library for reading semi-raw user input from terminals. Semi-raw as in, we can't detect if the user pressed the Control key alone, and the function keys are a mystery. What is supported, however, is:

• Regular characters

• Control+[key]

• Alt+[key]

• Control+Alt+[key]

This is a system for two dimensional computational geometry for Common Lisp.

Note: the system assumes exact rational arithmetic, so no floating point coordinates are allowed. This is not checked when creating geometric objects.

NJSON aims to make it convenient for one to decode, encode, and process JSON data, in the minimum keystrokes/minutes possible.

NJSON is parser-independent, with existing Common Lisp JSON parsers being loadable as additional system. jzon is included by default, though. Conveniences that NJSON provides are:

• encode and decode as single entry points for JSON reading and writing, be it from streams/string/files, or from those.

• jget, jcopy, jkeys, and their aliases to manipulate the decoded objects' properties without the need to worry about the low-level details of how these values are decoded.

• jif, jwhen, jor, jand, and other macros mimicking Lisp ones, while using truth values of JSON-decoded data.

• jbind and jmatch macros to destructure and validate parsed JSON.

• njson/aliases package to nickname to j for all the forms conveniently accessible as j:get, j:copy, j:if etc.

This a Common Lisp library to convert geographic coordinates between latitude/longitude and Open Location Code.

CL-TYPESETTING is a cross-platform Common Lisp typesetting library for all kind of typesetting applications.

This package provides a shim between Python3 (specifically, the CPython implementation of Python) and Common Lisp.

Enables fast and convenient interoperation with foreign objects.

Max’s Parser Combinators is a simple and pragmatic library for writing parsers and lexers based on combinatory parsing. MaxPC is capable of parsing deterministic, context-free languages, provides powerful tools for parse tree transformation and error handling, and can operate on sequences and streams. It supports unlimited backtracking, but does not implement Packrat Parsing. Instead, MaxPC achieves good performance through its optimized primitives, and explicit separation of matching and capturing input. In practice, MaxPC parsers perform better on typical computer languages—when compared to Packrat parsers—at the expense of not producing linear-time parsers.
