LE is a text editor which appears something like the Norton Editor, but has many additional features:

  • rectangle select/copy/paste (block type is switchable)
  • search/replace with regular expressions
  • filtering block contents through an external program
  • linear multilevel undo/redo
  • customizable menus
  • color syntax highlighting (using regular expressions in an external file)
  • handles UTF-8 characters, based on locale settings
  • customizable keymaps for different terminal types (associating either literal strings or terminfo capability names)
  • hexadecimal editing mode
  • editing of mmap'd files or devices in replace mode
  • frame drawing mode (first seen in Lexicon)
  • file selection box (inspired by Turbo C)
  • built-in postfix calculator.

It uses ncurses for display, mouse and part of the keyboard handling. The application has a built-in table of key assignments for xterm, rxvt and some less familiar terminal types.

History[edit]

According to the HISTORY file in its sources, Alexander V. Lukyanov started writing it in 1993 while using a BESTA machine. Over the next four years, he rewrote it into C++, and published it in 1997 with the GPL license.
