Lukyanov's terminal text editor, notable for block operations, binary-safe editing, hex mode, mmap-based large-file/device editing, syntax highlighting, and configurable keymaps and colors. ### 项目历史 The upstream HISTORY file says Lukyanov started LE in 1993 as first-year laboratory work at Yaroslavl State University while using a BESTA Unix machine with 8 MB of memory and fourteen terminals. The first version could load, browse, insert, delete, and save files. After that first version, the editor was almost completely rewritten in C++. Lukyanov published it under the GPL in early 1997 after deciding it had become powerful enough to share. The NEWS file marks version 1.2.0 as the first public release. LE's development history is a long record of terminal-editor pragmatism: regular-expression search, tunable syntax highlighting, rectangular blocks, mmap editing for large files and devices, mouse support, multibyte/UTF-8 support, full undo/redo, many syntax definitions, ncurses portability fixes, and build fixes for Unix-like systems. ### 采用历史 LE never became a mainstream editor on the scale of vi, Emacs, nano, or joe, but it persisted in Unix package collections because it occupies a useful niche: a small terminal editor with Norton Editor-like ergonomics plus block, binary, and hex-oriented features. Package availability in Homebrew, Debian, Ubuntu, and MacPorts shows the usual long-tail survival path for mature terminal tools: stable enough to keep packaging, specialized enough that users seek it by name. ### 使用方式 LE is used as an interactive terminal editor for text files, DOS/Unix line-ending files, binary-clean editing, hexadecimal viewing/editing, syntax-highlighted source/config editing, rectangular and stream block operations, and cautious mmap replace-mode edits of large files or devices. Its configuration model is file-based and terminal-oriented: syntax rules can live in package data, ~/.le/syntax, or ./.le.syntax; keymaps and colors can be dumped and customized in ~/.le or package data locations. ### 为什么软件包爱好者会关心 LE is significant as a survivor from the 1990s Unix editor ecology. It is small, C++/ncurses-based, GPL-licensed, and full of features that matter to terminal users who edit awkward files: rectangular blocks, binary mode, hex mode, mmap editing, and configurable keymaps. For package maintainers, LE is a good example of a stable but actively patched classic utility whose changelog is dominated by portability, terminal behavior, syntax updates, and correctness fixes rather than product churn. ### 时间线 - 1993: Alexander V.
