Usage:

Copy lusty-explorer.el somewhere in your load-path, or if if you use MELPA, then:

M-x package-install
=> Install package: lusty-explorer

Add this line to your ~/.emacs.d/init.el:

(require 'lusty-explorer)

To launch lusty:

M-x lusty-buffer-explorer
M-x lusty-file-explorer

And then use as you would switch-to-buffer or find-file or ido-find-file. Files/buffers are filtered using the LiquidMetal fuzzy/flex matching algorithm. Dotfiles are hidden by default but you can show them by entering ..

Keybindings to navigate matches:

• TAB - choose the highlighted item; open a file or buffer, descend into a directory
• RET - ditto, but create the file/buffer if there are no matches
• C-n / C-p - highlight next item, previous item in the current column
• C-f / C-b - highlight next column, previous column
• C-s / C-r - ditto
• C-x d - Launch dired within the current directory
• C-x e - Create a new buffer with the entered name
• Evil bindings: j, k, C-f, C-b

If you add (lusty-explorer-mode) to your ~/.emacs.d/init.el, these global bindings take effect:

• C-x b - lusty-buffer-explorer (in place of switch-to-buffer)
• C-x f - lusty-file-explorer (in place of find-file)

Customization:

To modify the keybindings, use something like:

(add-hook 'lusty-setup-hook 'my-lusty-hook)
(defun my-lusty-hook ()
  (define-key lusty-mode-map "\C-j" 'lusty-highlight-next))

Recent changes:

Spring 2020:

Bringing this old package closer to the conventions and quality-of-life standards of Emacs packages of 2020

• Presentation:
  • The buffer/window for displaying matches properly stretches the full frame and resizes itself more exactly.
  • Look-and-feel changes in the spirit of e.g. which-key and Hydra.
• Robustness:
  • If the package crashes or exits in an unexpected way, it cleans itself up;
  • Can now dismiss lusty when the matches window is selected using q or C-g or ESC ESC ESC;
• Correctness:
  • Buffer recency is according to the ordering of the current frame rather than the global ordering;
• Performance improvements for working in directories having many thousands of files;
