Most programming languages use CamelCase ("anIdentifier") naming conventions for identifiers. With Evil, you could navigate inside those identifiers using Evil built-in motions is the [count]f{char} motion, i.e. f{uppercase-char} or f_, respectively. But I would like to have this easier. I noticed there are many plugins available for Vim, which enables you to move camelCase-wise.

These packages defines motions ,w ,b and ,e (similar to w b e), which do not move word-wise (forward/backward), but Camel-wise; i.e. to word boundaries and uppercase letters. Outside of "words" (e.g. in non-keyword characters like // or ;), the new motions move just like the regular motions.

For example, with the CamelCase plugin the cursor ([]) is on the following sentence:

[]AnotherExampleOfFoobar

When I type dw, it will change to the following:

[]ExampleOfFoobar.

When I googled around for an alternative package for Evil, I found no alternative package for CamelCase motion. It deletes the whole AnotherExampleOfFoobar, instead deleting Another.

So I guess there is a missing feature, that I need to implement it in some way. So have anyone any suggestion to start with it?

    You're probably looking for subword-mode. – Dan Aug 03 '15 at 21:37

  • @wasamasa Thanks wasama, after trying out evil-little-word package, it seems it adds new commands next to the existing Evil commands. It adds a layer of complexitiy to Evil, which I don't want. The CamelCase plugin in Vim works with the default Vim commands. It stops on subwords, I would prefer that, instead adding new commands from evil-little-word next to the default Evil commands. Any suggestion? – ReneFroger Aug 10 '15 at 13:26
  • Perhaps this can work, but we just remap things like w to evil-forward-little-word-end and iw to evil-inner-little-word? I'm not sure about how to rebind evil keybindings, but it seems like a promising approach... – modulitos Feb 07 '16 at 11:24

Using the evil-little-word library as suggested by @wasamasa above, you can rebind your standard vim bindings to the evil-little-word versions.

For example, once you load that library in your path, put this in your init file:

(require 'evil-little-word)
(define-key evil-normal-state-map (kbd "w") 'evil-forward-little-word-begin)
(define-key evil-normal-state-map (kbd "b") 'evil-backward-little-word-begin)
(define-key evil-operator-state-map (kbd "w") 'evil-forward-little-word-begin)
(define-key evil-operator-state-map (kbd "b") 'evil-backward-little-word-begin)
(define-key evil-visual-state-map (kbd "w") 'evil-forward-little-word-begin)
(define-key evil-visual-state-map (kbd "b") 'evil-backward-little-word-begin)
(define-key evil-visual-state-map (kbd "i w") 'evil-inner-little-word)

I think that covers the bindings, but let me know if I am missing something!

To figure this out, I asked another question here about the details of re-binding evil-mode keys.

  • Whoa, that worked surprisingly well. Sorry for the belated response. But I couldn't get it working earlier. Later I thought I could give a try again, and it works now! Thanks for that, it's appreciated! – ReneFroger Feb 13 '16 at 23:19

    Haha, your welcome! As with most things in life (and emacs), it was a concerted effort. Thanks wasamasa for finding the library, and @Dan for helping with the configuration. Enjoy :D – modulitos Feb 14 '16 at 08:19
  • This was very helpful, thanks. It's nice to know that this still lets you replace the whole word with cio! – sk29910 May 13 '18 at 20:26
