LispWorks is computer software, a proprietary implementation and integrated development environment (IDE) for the programming language Common Lisp. LispWorks was developed by the UK software company Harlequin Ltd., and first published in 1989. Harlequin ultimately spun off its Lisp division as Xanalys Ltd., which took over management and rights to LispWorks. In January 2005, the Xanalys Lisp team formed LispWorks Ltd. to market, develop, and support the software. LispWorks's features include: The Enterprise edition also includes KnowledgeWorks, which supports rule-based or logic programming (including support for Prolog); the CommonSQL database interface; and a Common Object Request Broker Architecture (CORBA) binding. In September 2009, it was announced that LispWorks 6 would support concurrent threads and the CAPI graphics toolkit had been extended to support GTK+. LispWorks 6.1, released in January 2012, included 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.
