What is "lispworks"

Wikipedia
LispWorks

LispWorks is a commercial implementation and Integrated Development Environment for the Common Lisp programming language. The software runs on Microsoft Windows, Mac OS X (Intel), Linux (ARM and Intel), FreeBSD, Solaris (x86/x64, SPARC) and AIX. A runtime version for Android and IOS is available.

LispWorks was developed by the UK software company Harlequin Ltd., and first published in 1989. Harlequin ultimately spun off its Lisp arm as Xanalys, which took over management and rights to LispWorks. In January 2005, the Xanalys Lisp team formed LispWorks Ltd. to market, develop, and support the LispWorks software.

Some of LispWorks's features are

  • a native-code compiler and an interpreter for an extended ANSI Common Lisp
  • an implementation of the Common Lisp Object System with support for the Metaobject protocol
  • support for 32bit and 64bit versions
  • native threads and symmetric multiprocessing
  • Unicode support: it can read and write Unicode files and supports strings encoded in Unicode
  • Foreign Language Interface (FFI) for interfacing with routines written in C
  • a Java interface
  • the Common Application Programmer's Interface (CAPI) GUI toolkit, which provides native look-and-feel on Windows, Cocoa, GTK+ and Motif
  • an Emacs-like editor (source code is included in the Professional edition)
  • a Lisp Listener, which provides a Common Lisp Read Eval Print Loop
  • a graphical debugger, inspector, stepper, profiler, class browser, etc.
  • a facility to generate standalone executables and shared libraries. To reduce memory size, a tree shaker can be used to remove unused code and data.
  • on Mac OS X it provides a bridge to Objective-C for using Apple's Cocoa libraries
  • many of the libraries are written using the Common Lisp Object System and can be extended by the user (by writing subclasses and new methods)

The Enterprise edition also includes KnowledgeWorks, which supports rule-based programming (including support for Prolog); the CommonSQL database interface; and a CORBA binding.

In September 2009, it had been announced that LispWorks 6 would support concurrent threads and the CAPI graphics toolkit has been extended to support GTK+. LispWorks 6.1, released in January 2012, includes many further enhancements to CAPI, such as support for anti-aliased drawing.

LispWorks ran on the spacecraft Deep Space 1. The application called RAX won the NASA Software of the Year award in 1999.
