visual selection and X primary behavior
by Linus Arver 27 Jan '15

27 Jan '15

Hello all, In regular Emacs (with Evil mode turned on, of course), I can (1) do visual selection of a region, and it will automatically copy that selection into the X primary selection buffer. This way, I can simply do SHIFT+INSERT in another X program (e.g., Firefox) and I will paste the selection that way. Conversely, I can (2) SHIFT+INSERT into Emacs/Evil (in Insert mode), and it will paste whatever is in the X primary buffer. However, behavior (1) does not work in terminal-mode Emacs (`emacs -nw`), although behavior (2) works as expected. I have tried to work around this by using my `"+y` macro which is enabled with (define-key evil-normal-state-map ",y" "\"+y") in my .emacs, but it fails with the message After 0 kbd macro iterations: X selection unavailable for this frame . Is this a bug in Evil or is it something in Emacs itself? -L

Mapping ( and ) in paredit mode
by Nikolai Weibull 01 Oct '14

01 Oct '14

Hi! I would like to map ( and ) as prefix keys to various other mappings to paredit mode functions: (evil-define-key 'normal paredit-mode-map "((" 'evil-paredit-backward-slurp-sexp "))" 'evil-paredit-forward-slurp-sexp ...) This only works after a while for inexplicable reasons when you’ve clicked around a bit and tried to execute a couple of mappings in a buffer with Paredit enabled. The problem is that ( is mapped to backward-sentence in evil-motion-state-map, which seems to take precedence. How do I go about removing the mapping of ( to backward-sentence in evil-motion-state-map for buffers that have Paredit enabled? (I’m sure that this worked without any issues before, but I’ve changed my configuration somewhat and now I get this weird behavior.) Oh, using (define-key evil-normal-state-local-map "((" 'evil-paredit-backward-slurp-sexp) seems to work. So is that the preferred way of solving this situation?

Remap C-SPC binding
by RC 23 Sep '14

23 Sep '14

evil-mode seems to take over the C-w and C-SPC key bindings. I was able to unbind C-w using the following commands, but C-SPC still seems bound in insert mode. (eval-after-load "evil-maps" (dolist (map '(evil-motion-state-map evil-insert-state-map evil-emacs-state-map)) (define-key (eval map) "\C-w" nil))) (eval-after-load "evil-maps" (dolist (map '(evil-motion-state-map evil-insert-state-map evil-emacs-state-map evil-insert-state-local-map )) (define-key (eval map) (kbd "C-SPC") nil))) I am using emacs 24.3 and updated evil from MELPA. Any suggestions to fix this will be appreciated.

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!
