Using ido for Emacs completion
I’m a heavy user of ido – it handles all of my completion,
find-file, or whatever else.
However, ido’s default configuration leaves much to be desired:
- The way it displays results by default is quite difficult to read, as you can’t quickly skip your eyes to the next item when they’re all listed in a single wrapped line.
- The default completion is prefix-only
- It’s not obvious how to make ido actually complete everything
Fortunately this is all quite fixable with a few packages and a little configuration:
ido-everywhere, when set to
t, puts ido in more places than the default.
ido-virtual-buffersdoesn’t fix anything per se, but it does add recentf files to
find-filecompletion, which is really handy.
- ido-vertical-mode makes ido display each result on its own line, with a configurable amount of lines to display at a time (though I just use the default).
- flx-ido fixes the completion by using the flx completion engine.
- ido-hacks and ido-ubiquitous together make ido complete everything I’ve wanted so far.
My full ido configuration is as follows:
(use-package ido :quelpa :config (setq ido-auto-merge-delay-time 99999999) (setq ido-everywhere t) (setq ido-virtual-buffers t) (ido-mode)) (use-package flx-ido :quelpa :requires ido :config (flx-ido-mode)) (use-package ido-vertical-mode :quelpa :requires ido :config (ido-vertical-mode)) (use-package ido-hacks :quelpa (:stable nil) :requires ido :config (ido-hacks-mode)) (use-package ido-ubiquitous :quelpa :requires ido :config (ido-ubiquitous-mode))
