Textadept is a fast and ridiculously extensible cross-platform text editor for programmers.
Features:
Textadept’s user interface is sleek and simple. Relentlessly optimized for speed and minimalism over the years, the editor consists of less than 2000 lines of C code and less than 4000 lines of Lua code.
Textadept is an ideal editor for programmers who want endless extensibility without sacrificing speed or succumbing to code bloat and featuritis. The editor gives you complete control over the entire application using the Lua programming language. Everything from moving the caret to changing menus and key commands on-the-fly to handling core events is possible. Its potential is vast.
