CLISP is an implementation of theprogramming languageCommon Lisp originally developed by Bruno Haible and Michael Stoll for theAtari ST. Today it supports theUnix andMicrosoft Windowsoperating systems.
CLISP includes aninterpreter, abytecodecompiler,debugger,socket interface, high-level foreign language interface, stronginternationalization support, and twoobject systems:Common Lisp Object System (CLOS) andmetaobject protocol (MOP).
It is written inC andCommon Lisp. It is now part of theGNU Project and isfree software, available under the terms of theGNU General Public License (GPL).
Haible did not originally intend to distribute CLISP under the GPL, but in a well-publicised email exchange withRichard Stallman, he eventually agreed to do so. The issue at stake was whether CLISP was aderivative work of theGNU readlinelibrary.[1]
CLISP is extremely portable, running on almost allUnix-basedoperating systems as well as onMicrosoft Windows. Although interpreting bytecode is usually slower than running compiled native binaries, this is not always a major issue (especially in applications like Web development where I/O is the bottleneck). CLISP is also easier to set up than other popularFOSS Common Lisps such asSBCL.
Paul Graham used CLISP to run the software for hisViaweb startup. Viaweb was an earlyweb application; portions of it still exist asYahoo! Stores, the base for Yahoo Shopping[citation needed].
Conrad Barski'sLand of Lisp uses some CLISP-specific functions in the textbook exercises.
