"Zile has all of Emacs's basic editing features: it is 8-bit clean (though it currently lacks Unicode support), and the number of editing buffers and windows is only limited by available memory and screen space respectively. Registers, minibuffer completion and auto fill are available. Function and variable names are identical with Emacs's (except those containing the word "emacs", which instead contain the word "zile"!).
However, all of this is packed into a program which typically compiles to about 130Kb."
That's fascinating. A similar effort is Mitchell Foicica's TextAdept. TextAdept uses the Scintilla editor control, but most of the editor is actually written in Lua. --DMcCunney 06/22/16
