OpenLisp is a programming language in the Lisp family developed by Christian Jullien. It conforms to the international standard for ISLISP published jointly by the International Organization for Standardization (ISO) and International Electrotechnical Commission (IEC), ISO/IEC 13816:1997(E), revised to ISO/IEC 13816:2007(E).Written in the programming languages C and Lisp, it runs on most common operating systems. OpenLisp is designated an ISLISP implementation, but also contains many Common Lisp-compatible extensions (hashtable, readtable, package, defstruct, sequences, rational numbers) and other libraries (network socket, regular expression, XML, Portable Operating System Interface (POSIX), SQL, Lightweight Directory Access Protocol (LDAP)).OpenLisp includes an interpreter associated to a read鈥揺val鈥損rint loop (REPL), a Lisp Assembly Program (LAP) and a backend compiler for the language C..
