Textadept
Textadept is a free software minimalist text editor designed for computer programming. Distributed under the MIT license, it is written in C and Lua and is extensible using Lua. Textadept can use either a graphical user interface or a text-based user interface when running in a terminal window. Textadept uses the Scintilla editing component. Textadept's developer makes the curses wrapper library for Scintilla used by Textadept available separately. In common with Emacs, Textadept is deeply extensible; the Lua API has access to any subsystem of the program. Despite this, the developer states that one of his goals  is for the C portion to not exceed 2000 lines of code and for the Lua portion to never exceed 4000 LOC. When running in a graphical interface Textadept purposely does not save window size or position, leaving this up to the window manager.
