TDE (Thomson–Davis Editor), also called the TDE programmer's editor, is a public-domain, cross-platform, console-mode text editor written in C. It targets programmers and technical writers, and runs under DOS, Windows (Win32/Cygwin), and Unix-like systems.[1][2]
History and development
TDE was created by Eric Pement and released into the public domain, later maintained by Jason Hood.[3]
Features
TDE provides a range of console-oriented editing capabilities:[3]
- Console-mode operation – no GUI required
- Keyboard remapping, with custom keymaps including WordStar-style bindings
- Macros for automating editing tasks
- Drawing mode using IBM OEM line-drawing characters
- Resizable block to measure string width
- Window splitting and two-file comparison with synchronized scrolling
- Syntax highlighting with user-definable lexers
- Custom help menus editable by users
- Change tracking – flags unsaved edits
Reception
Users value TDE for its lightweight nature, portability, and rich console-based features. One user described it as "powerful and light and infinitely customisable".[3] Eric Pement places TDE second in his personal use, just behind GNU Emacs.[4]
Comparison
TDE differentiates itself from GUI editors like Notepad++ or UltraEdit by operating entirely in console environments. It shares use-case similarities with vi and Emacs, but is distinct in its keyboard customizability and multi-file compare tool.[3]
