~wen~ is an experimental terminal text editor, written during the Winter 2022 batch at the [[https://www.recurse.com/][Recurse Center]]. It was an exploration of terminal raw mode, ANSI escape sequences, and UTF-8 / wide-character glyph rendering. It works only as a very simple text editor.
|
||
|
|
|
||
|
|
A motivating idea behind ~wen~ was to keep the editor itself minimal. Text manipulation would be delegated to external programs and saved shell snippets. Selected regions would be piped through standard input and output; for example:
|
||
|
|
|
||
|
|
- Convert case: ~tr '[:lower:]' '[:upper:]'~
|
||
|
|
- Sort and deduplicate lines: ~sort -u~
|
||
|
|
- Reflow paragraphs or align columns: ~fmt -w 72~, ~column -t~
|
||
|
|
- Search and replace: ~sed 's/foo/bar/g'~
|
||
|
|
|
||
|
|
This piping mechanism was left unimplemented, along with undo/redo, line numbers, jumping to characters, Unicode combining marks, and bidirectional text support.

** Usage
|
||
|
|
|

wen [file]

If no file is specified, ~wen~ opens a scratch buffer in ~$XDG_CACHE_HOME/wen/scratch~.
|
||
|
|
|
||
|
|
Logs are written to ~$XDG_CACHE_HOME/wen/log~.
