|Hemlock: an extensible Emacs-like editor|
Hemlock is 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.
The Scribe sources for these documents are distributed with the CMUCL source code, in the src/docs/hem directory.
To start experimenting with Hemlock, load the CLX and Hemlock subsystems, then type (ed). This should open an X11 window for the editor (actually two windows; the smaller window contains the minibuffer).
* (require :clx) * (require :hemlock) * (ed)
The keybindings in the editor are similar to those in GNU Emacs: for instance M-x enters the minibuffer, and C-x C-f opens a file for editing (enter the filename in the minibuffer). Completion in the minibuffer works with #\Space, not with #\Tab. Command names are of the form Find File rather than find-file. Dired mode is available with M-x Dired. To quit Hemlock and return to the listener, type C-x C-z.
Note that the tty code in Hemlock requires termcap (on Debian systems, you can install the termcap-compat package). For further notes on using Hemlock, see CLiki:CloserLookAtHemlock.
