Extension Language Kit

Extension Language Kit (ELK) is a <a href="/facts/Free_software/IaoVtJXn">free</a> <a href="/facts/Scheme_(programming_language)/0aGdf3SC">Scheme</a> implementation which is embeddable in <a href="/facts/C_(programming_language)/Ky2No763">C</a> and <a href="/facts/C%252B%252B/Et0F2qn9">C++</a> programs, but can also be used as a stand-alone Scheme interpreter. It is available under a custom permissive license for any use, commercial or noncommercial.
Elk was written by Oliver Laumann and Carsten Bormann to provide an Extension Language for the development of large C++-based systems such as the <a href="/facts/Open_Document_Architecture/aqlfLeLc">ODA</a> document editor ISOTEXT and the videoconferencing system TELES.VISION. It was inspired by the Lisp interpreter in <a href="/facts/Emacs/BvGxuAxQ">Emacs</a> and has in turn helped inspire developers of other dynamic language interpreters such as Matz' <a href="/facts/Ruby_(programming_language)/BeYSaPSR">Ruby</a> Interpreter.
In 2005 <a href="/facts/Sam_Hocevar/x08sv2KF">Sam Hocevar</a> became the current maintainer of the Elk scheme project, merging contributed patches and fixing known bugs.
However, as of October 2024, the Elk webpage has been blanked, and Hocevar has not responded to queries about the status of the project or whether the site will be brought back.
