OpenLisp is a KISS (Keep It Simple, Stupid) full conforming implementation of ISO/IEC 13816:2007 ISLISP Language, the International Standard version of Lisp. Entirely written in C, OpenLisp has been ported on more than 90 different architectures (compiler/OS/processor) from small 16 bits MS-DOS systems to 64 bits systems such as DEC Alpha processor. All major processors (Intel 16/32 bits, Intel IA64, AMD/Intel EM64T, Sparc 32 bits and UltraSparc 64 bits, Motorola 68k and 88k, RS6000, PowerPC, MIPS R3000/R4x00/R8000/R10000, HP PA 32 and 64 bits mode, Alpha 32 and 64 bits mode, IBM s390, StrongARM, VAX) are supported. It even runs on Pocket PC.

OpenLisp is essentially a very fast interpreter (see benchmarks) that competes in speed with some CLtL compilers. It also has a compiler that produce LAP to be interpreted by a native virtual machine. You can even make standalone applications using the C code backend that also will make your code run from 10 to 20 times faster. OpenLisp is written in ISO C for the kernel and using POSIX like interface for the operating System when available. In the usual case, a new UNIX port is as simple as:

$ ./configure; make; make install

The goal of OpenLisp is to provide an efficient, modern and complete Lisp System for those whom want embedded Lisp processing in more conventional applications written in C, C++, Java or Visual Basic. Even if OpenLisp can be used with a toplevel loop and with all goodies that an old-timer lisp user enjoy, it is more tailored to be transparently integrated in native C or C++ applications. For this purpose, OpenLisp is distributed mainly as a Lisp library (or DLL on Microsoft world) that you can integrate into your main application. It can also be compiled as a COM or CORBA server. The memory footprint is very small with less than 200 Kbytes for the complete kernel and less than 400 Kbytes for a usable Lisp System data. There is no limit on the maximum memory that the System can use. With little efforts, you can exchange data between C and Lisp. OpenLisp extends the ISLISP standard to ease port from other Lisp Language, mainly Common Lisp. The kernel can be compiled to support the UNICODE IS0/IEC 10646-1:1993 (16 bits) character sets with UTF-16 encoding instead of the IS0 8859-1 (8 bits) character sets. It also provides a consistent interface to communicate using Lisp streams with BSD, POSIX sockets and/or WinSocks sockets.


Main features:

  • Conforming implementation of ISO/IEC 13816:2007(E) ISLISP Language.
  • Library extensions: defstructs, hash-tables, profiler, editors, sequence, regular expressions ...
  • High level of portability (> 90 systems from 16 to 64 bits processors - list here).
  • Entirely written using ISO/IEC 9899:1990 C Programming Language. (no external package or library required).
  • Extension of ISLISP I/O streams to support BSD, Winsock or POSIX sockets when available.
  • Extension of ISLISP to support UNICODE character sets (on Windows NT and some unixes like Linux and Solaris).
  • Easily extensible in C or C++ with automatic external interface. (see sample)
  • Portable LAP compiler (code is form 2 to 4 times faster). (see sample)
  • C backend compiler (code is form 10 to 20 times faster). (see sample)
  • Execore that combine a core image and OpenLisp into a standalone executable.
  • Daemon mode where OpenLisp can be used as a daemon process (Unix).
  • Virtual allocator and memory manager.
  • Fully integrated with GNU Emacs editor. (screenshot)
  • OpenLisp Server Page module (call Lisp from an HTML page). (see sample)
  • Process functions to act as a server (fork, wait, waitpid, kill).
  • Code can be compiled as DLL or shared library.
  • Can be used with a database (using ODBC link).
  • Can be used with MySQL and PostgreSQL server (both using ODBC and native client interface).
  • Can read from an write to pipes (UNIX and WIN32).
  • Can be compiled as COM, DCOM or CORBA server.
  • Can be used as a shell language (#!/usr/bin/openlisp). (see sample)
  • Can be used as CGI script language.
  • Can be used as a JNI JAVA module. (see sample)
  • Can run as a standalone HTTP server. (see sample)
  • Can get URL using HTTP/1.1 protocol. (see sample)
  • Can send mails using SMTP protocol. (see sample)
  • Can read news using NNTP protocol. (see sample)
  • Can be used to read XML file as easy as 'read'. You can read the complete file or only sub-trees, one at a time.
  • Can be used with mod_lisp, an Apache module to write Internet applications in Lisp.

Hints to test the UNICODE version.

The Windows UNICODE version works only on Windows NT/2000/XP (not on Windows 95/98). After launching OpenLisp, select Option and choose a font that supports UNICODE (MingLiU works well for Japanese on my computer - even on US NT). You can play with a rudimentary Emacs like editor and edit a sample file UNICODE that reside on ./contrib/fibwide.lsp.

(edit "./contrib/fibwide.lsp") (see screenshot)
