For some reason I had it in my mind that swiper<\/a> depended on Lispy<\/a>, or Spacemacs<\/a>, or some other Vim-derived Emacs mode so I never really looked at it. Then I read Mike Zamansky’s post on swiper<\/a> and had my eyes were opened. At a minimum, swiper<\/code> is a much improved replacement for Emacs’s incremental search. You can take a look at Zamansky’s post to see how it improves on the default incremental search behavior1<\/a><\/sup>, but the TL;DR is that you get a sort of simplified regex search with all the candidates shown in the minibuffer. You can navigate this list with the usual \u3010Ctrl<\/kbd>+n<\/kbd>\u3011 and \u3010Ctrl<\/kbd>+p<\/kbd>\u3011 and then select the match you want. <\/p>\n

It turns out, though, that once you have the underlying ivy<\/a> mode installed everything gets better. You can get rid of ido-mode<\/a> and smex<\/a> and let ivy take care of the things they do. All the things you loved about ido-mode are done better with ivy. There’s a very nice manual<\/a> to explains everything ivy<\/code>2<\/a><\/sup> can do <\/p>\n

Watch Zamansky’s video on swiper\u2014and the rest of his videos if you haven’t already\u2014to see why this is a worthwhile upgrade. I’m still cautiously feeling my way with swiper and have started small. Here’s my current configuration: <\/p>\n

\n
(use-package<\/span> swiper<\/span>\n  :ensure<\/span> t\n  :config<\/span>\n  (ivy-mode 1)\n  (setq<\/span> ivy-use-virtual-buffers t)\n  (global-set-key \"\\C-s\"<\/span> 'swiper)\n  (global-set-key (kbd \"C-c C-r\"<\/span>) 'ivy-resume)\n  (global-set-key (kbd \"M-x\"<\/span>) 'counsel-M-x)\n  (global-set-key (kbd \"C-x C-f\"<\/span>) 'counsel-find-file))\n<\/pre>\n<\/div>\n
 As you can see, I’m using it for find-file<\/code> and execute-extended-command<\/code> as well as isearch<\/code>. Again, I’m starting cautiously but so far I think it’s a definite win. <\/p>\n

 One small annoyance is that there’s a slight delay (a small fraction of a second) before the point moves to place selected. That may because the screen isn’t scrolled until you choose a match. <\/p>\n<\/div>\n<\/div>\n

 Ivy<\/code> is the library that does much of the heavy lifting for swiper<\/code>. <\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
