Directory mode
When you open a directory (C-x C-f and don’t choose a file,
but a directory), Lem shows a list of files and directories.
With Lem’s GUI frontend (SDL2), you can click on files and directories.
Here is a list of keybindings. Emacs’ Dired users will feel right at home.
| Key-combination | Function |
|---|---|
| “n” | next line |
| “p” | previous line |
| “q” | qui |
| “^” | go up one directory |
| “Enter” | visit the file or the directory at point |
| “Space” | read the file |
| “g” | update the directory buffer |
| “m” | mark file |
| “u” | unmark file |
| “U” | unmark all |
| “t” | toggle marks (the unmarked ones become marked) |
| “* !” | unmark all |
| “* %” | mark files and directories by regex |
| “Q” | query-replace in marked files and directories |
| “D” | delete marked files and directories (recursively, with confirmation) |
| “C” | copy marked files and directories |
| “R” | rename |
| “+” | make a directory |
Key bindings added after the Lem 2.0 release:
| Key-combination | Function |
|---|---|
| “s” | sort files and directories by mtime |
You can write your own commands to act on the selected files and directories.
Here’s how the built-in delete command is implemented:
(define-command directory-mode-delete-files () ()
(let ((files (selected-files (current-point))))
(when (prompt-for-y-or-n-p (format nil "Really delete files~%~{- ~A~%~}" files))
(dolist (file files)
(delete-file* file))
(update-all))))
We get the list of marked items with (selected-files (current-point)), do something, and update the buffer.
