Hemlock – an extensible Emacs-like text editor embedded in CMUCL. It follows the tradition of the Lisp Machine editor ZWEI and the ITS/TOPS-20 implementation of Emacs. Hemlock is able to display to a terminal, or use CLX for X11.
It was originally developed in Spice Lisp by Bill Chiles and Rob MacLachlan in 1984 at Carnegie-Mellon University in the United States on a PERQ machine, then taken back to Common Lisp by Scott Fahlman, from the University, after Spice Lisp’s Common Lisp implementation. Hemlock thus continued the long tradition of Lisp Emac implementations for Lisp machines or ITSITS/TOPS-20 systems.
Hemlock was later retained by a hacker community. An attempt to take Hemlock to other Common Lisp implementations began in 2002.
Hemlock is integrated into the Common Lisp compiler, interpreter and CMUCL development suite, but can also be used independently or not used at all for using CMUCL in GNU Emacs. It can be used in terminal or graphical mode with CLX, a low-level graphics library for X Window.
