Current recommended libraries

Cliki contributors (that's you!) believe that the libraries on this page are considered "good enough for government use", and serve as a starting point when looking for a library covering a given field.

Library management / installation / Handling Packages

• Quicklisp - A popular way of obtaining lisp libraries
• asdf - System definition, aka Makefiles(in some implementation like sbcl, this is already installed by default)

General purpose utility libraries and commonly used libraries

• alexandria - Collection of portable general purpose utilities. Used by a large number of other projects.
• iterate - iterate is a lispy and extensible replacement for the LOOP macro.
• closer-mop - A popular compatibility library allowing portable access to the MOP across implementations.
• Regular expressions: cl-ppcre - highly useful and fast regular expressions engine.
• Pattern Matching: optima - ML-style optimized pattern matcher.
• Collections:
  • lisp-interface-library is a collection of pure and stateful data structures in interface-passing style
  • FSet is a functional set-theoretic collections package
• Mathematics:
  • GSLL is an interface to the GNU Scientific Library
  • Maxima is a computer algebra system

System and low level management

• Threads: Bordeaux-Threads
• Files and directories: CL-FAD
• Sockets:
  • usocket is under active development; includes trivial-sockets compatibility
  • IOLib includes support for non-blocking IO (select, epoll, kqueue)
• OS Interface:
  • OSICAT or IOlib
  • inferior-shell
• Foreign language interface:
  • CFFI. Supports almost all lisp implementations on all platforms.
  • SWIG can generate CFFI bindings from C/C++ header files
• Memory management: trivial-garbage includes support for finalization and weak hash tables

Project managements

Logging:

• Log4CL is high performance extensible logging library for Common Lisp

Unit Testing:

• FiveAM is a simple regression testing framework
• Stefil is a test framework, and its philosophy is to stay as transparent as possible
• CLUnit is unit testing framework designed to be easy to use

Here's a report of various testing frameworks. see Also: Test framework comparison

Graphics libraries

Graphical User Interface:

• cl-gtk2
• gtk-cffi GTK3 interface, in active development
• CommonQt
• ltk

Graphical drawing library:

• vecto < cl-vectors < zpng : writing vector graphics on PNG format.
• cl-cairo2 : cairo binding for Common Lisp.

Web development

HTTP server and frameworks:

• Hunchentoot web server
• RESTAS web framework
• Clack web application environment for Common Lisp inspired by Python's WSGI and Ruby's Rack
• ningle lightweight web application framework
• Sytes is a small Common Lisp library for building simple website

Utilities:

• CL-WHO HTML generator
• Parenscript JavaScript compiler

HTTP client:

• Drakma - an HTTP/HTTPS client library with session managements and more.

SQL database connectivity:

• CLSQL
• CL-DBI Database independent interface for Common Lisp
• postmodern: designed for PostgreSQL
• hu.dwim.rdbms: nicer API than CLSQL; but not as many backends yet
• hu.dwim.perec: the ORM of choice (if you're into ORMs at all...); based on hu.dwim.rdbms

Internationalization (i18) and localization (l10n):

• Character encoding/decoding: flexi-streams - focus on features
• Character encoding/decoding: babel - focus on speed
• Character categories, etc: cl-unicode
• Localization (number formats, etc): cl-l10n

XML:

• CXML namespace, validating, SAX, StAX, W3C DOM, XPath 1.0, XSLT 1.0
• S-XML simple XML parser
• XMLS simple XML parser
