Emacs: Ido Mode Setup 👎

This page describe ido in Emacs 27 (Released 2020-08)

Make Ido Display Vertically

You can setup Ido Mode to display choices vertically, and turn on flex match.

Put this in your Emacs Init File:

(progn
  ;; make buffer switch command do suggestions, also for find-file command
  (require 'ido)
  (ido-mode 1)

  ;; show choices vertically
  (if (version< emacs-version "25")
      (setq ido-separator "\n")
    (setf (nth 2 ido-decorations) "\n"))

  ;; show any name that has the chars you typed
  (setq ido-enable-flex-matching t)

  ;; use current pane for newly opened file
  (setq ido-default-file-method 'selected-window)

  ;; use current pane for newly switched buffer
  (setq ido-default-buffer-method 'selected-window)
)

;; big minibuffer height, for ido to show choices vertically
(setq max-mini-window-height 0.5)
