What is the best way to rebind common keys?
by Alan Schmitt 23 Sep '14

23 Sep '14

Hello, I used evil a while back, but I stopped since the physical key positions were not practical (I was using a dvorak layout then). I would like to give evil a second try, but this time choosing my own keybindings adapted to my current layout (bépo). I thus have two questions. 1. Is there a summary of the default evil bindings, and the functions to which they are bound? 2. What is the recommended way to change bindings? I looked at http://www.emacswiki.org/emacs/Evil and it seems I could simply do a "(define-key evil-normal-state-map … …)". Is there a better way? Thanks, Alan -- OpenPGP Key ID : 040D0A3B4ED2E5C7

define-key versus evil-define-key
by Nikolai Weibull 18 Sep '14

18 Sep '14

Hi! What’s the preferred way of adding keys to a given mode’s map? Is (define-key evil-motion-state-local-map "\C-b" 'calendar-scroll-right-three-months) or (evil-define-key 'motion calendar-mode-map "\C-b" 'calendar-scroll-right-three-months) preferable? (From an ease-of-use perspective, the second is better, as it allows you to easily map more keys, but I’m wondering from a “the right way to do it” perspective.)

Motion in grep-mode
by Nikolai Weibull 17 Sep '14

17 Sep '14

Hi! Why isn’t grep-mode’s bindings overriding those defined in motion-state? Since grep-mode is derived from compilation-mode, I’d have thought that it’d work. I’ve also tried (evil-set-initial-state 'grep-mode 'motion) without success (even though (evil-motion-state-p) returns t).

Problem with parent keymap
by Albert Krewinkel 14 Sep '14

14 Sep '14

Hi, I just encountered some unexpected behavior when defining key bindings for maps which have parent maps: When I define a key for some state for the parent map as well as the child map, the child map overrides the bindings for the parent map. Here is what I mean: (defun alok-foo () (interactive) (message "foo")) (defun alok-bar () (interactive) (message "bar")) (defvar alok-mode-map (make-sparse-keymap)) (defvar alok-child-mode-map (let ((map (make-sparse-keymap))) (set-keymap-parent map alok-mode-map) (define-key map (kbd "M-<return>") 'alok-bar) map)) (define-derived-mode alok-mode prog-mode "ALOK" "Major ALOK mode") (define-derived-mode alok-child-mode alok-mode "calok" "ALOK derived mode") (evil-set-initial-state 'alok-mode 'motion) (evil-set-initial-state 'alok-child-mode 'motion) (evil-define-key 'motion alok-mode-map (kbd "f") 'alok-foo) (evil-define-key 'motion alok-child-mode-map (kbd "f") 'alok-bar) When I enter into alok-mode and press `f`, I would ecpect to see "foo" in the message area, but instead I get "bar". I tried to find the reason for this myself, but I got stuck quickly. Is there a way to work around this? Thanks in advance!

Evil-mode defining ex commands & redefining whole line commands (eg. dd)
by Russell Dunphy 14 Sep '14

14 Sep '14

Hi, new to Emacs (Evil-mode persuading me that it’s worth attempting the switch). Have a few questions. I’m trying to get adhoc key mappings working as they would in vim. So for example if I open a new Clojure file I might want to quickly set up a mapping to run it. In vim this would be something like: :map ,t :!lein exec %<CR> Is there a way to implement the `map` ex command in evil-mode to make creating arbitrary, temporary mappings like this possible and easy? Second question relates to trying to get evil-mode to play nicely with paredit. I’m using `evil-paredit-mode` which makes most things work, but whole line commands such as `dd` don’t seem to work, and I can’t work out how to rebind them. I’ve tried the following: (evil-define-key 'normal evil-paredit-mode-map (kbd “dd”) (lambda () (move-beginning-of-line) (evil-paredit-delete-line)) But I get the error “key sequence dd starts with non-prefix key d”. Thanks in advance for your help! Russell

evil-noautochdir : keeping the working directory the same as you work
by Gabriel Barta 11 Sep '14

11 Sep '14

Hi, I disliked the emacs behaviour where the current directory would always be the one containing the current file. So I wrote a bit of elisp to change it, named according to the equivalent setting in Vim. It actually leaves the emacs behaviour unchanged for compatibility with vanilla Emacs packages, and instead redirects evil to work with a different variable for the current directory. I originally had something that controlled the emacs default-directory variable instead, but the current approach gives a smoother experience. I'd love to hear your feedback. The repo can be found at https://github.com/gbarta/evil-noautochdir I think it would be great to have this as part of Evil, but I am not sure if anyone else is interested in this aspect of compatibility with Vim. If you are, let me know!

Issues Integrating Other Modes With Evil-Mode
by Tad Ashlock 24 Aug '14

24 Aug '14

I'm attempting to integrate org-mode with evil-mode. I'm aware of the existing evil-org-mode, but what I'm attempting is much deeper. Rather than just adding some evil keybindings to some org functions, I want the basic evil operations to work on org files. That is, evil-mode operators, commands, and motions are org-aware. I see that when evil-mode is in the normal state: * the user presses 'x', which is bound to evil-delete-char * evil-delete-char calls evil-delete * evil-delete calls Emacs's delete-region to perform the deletion When my new evil-org-mode (a minor mode) is active, I need evil-delete-char to call org-delete-char to perform the deletion. Not directly, of course. The following seems to work. (defun evil-org-delete-region (beg end) (let ((N (- end beg))) (save-excursion (goto-char beg) (org-delete-char N)))) (evil-define-operator evil-org-delete-char (beg end type register) "Delete next character." :motion evil-forward-char (interactive "<R><x>") (cl-letf (((symbol-function 'delete-region) #'(lambda (beg end) (evil-org-delete-region beg end)))) (evil-delete beg end type register))) (define-key evil-org-mode-map [remap evil-delete-char] #'evil-org-delete-char) Essentially, I remap evil-delete-char to evil-org-delete-char. This new function temporarily redefines delete-region to be evil-org-delete-region, which, in turn, calls org-delete-char. Then the subsequent cal l to evil-delete will call org-delete-char with no changes to the evil-mode source code. Great! But... (1) This approach gets more complicated for other evil-mode functions. * For example, evil-org-delete-backward-char-and-join requires more indirection in order to restore the function-cell value of delete-backward-char, because that's what the org-mode function needs to call. * Remapping a remapped binding doesn't chain. And it appears that remapping a binding in my minor mode doesn't override the remapped binding that evil-mode does. For example, if I remap delete-backward-cha r in evil-org-mode, the evil-mode (insert state) binding (evil-delete-backward-char-and-join) still gets called. * I can't figure out how to intercept operators like "dd" (delete whole line), in order to override their low-level Emacs calls. (2) This approach isn't composable. That is, another minor mode could not integrate with evil-mode while evil-org-mode is active. Questions: (1) Is there a good, clean, composable, way of doing what I'm trying to do? (2) If not, is there an acceptable change that could be made to evil-mode to support what I'm trying to do? A change that improves the ability to integrate with evil-mode in general, not just for my purpose? If the answer to question (1) is 'no', I'm thinking the answer to question (2) might be something along the lines of replacing evil-mode's calls to fundamental Emacs text manipulation commands (like delete-regio n) with (abnormal) hooks. Each hook would default to being the command currently being called directly, but could be made buffer local and modified by another mode to support awareness of the buffer's contents. This would also allow, in theory, multiple modes to hook into the actions. Although I can't quite picture how this would work cleanly in practice. Thank you, --Tad

cursor: make underlying letter bold
by Linus Arver 09 Aug '14

09 Aug '14

Hello, In GVim, when I move my cursor around in normal mode, the letter underneath the cursor position becomes bolded. Is there a simple way to do the same thing in Evil? Or, is this is more of a syntax highlighting issue? While I'm not a Lisp expert, I can see that my request involves `evil-set-cursor` in evil-common.el... -L

Include underscore in word
by Bob Nnamtrop 30 Jul '14

30 Jul '14

This seems like a trivial question but a lot of searching has not produced an answer. I'm trying to make the change from viper to evil. One thing that surprises me is the underscores are not considered part of a work for various word commands (e.g, w, cw, etc). I tried vim and they are considered part of the word and in viper they are as well. I find the choice in evil strange. Is there a way to make underscores part of words in evil? Thanks, Bob
