<backspace> not bound properly in haskell-mode
by Keshav Kini 25 Jul '14

25 Jul '14

When I have a .hs file open in a buffer (i.e. with haskell-mode activated), it seems that typing <backspace> in <N> state actually deletes characters. Investigating a bit, I see that in other modes - such as message-mode, in which I'm typing this email - doing describe-key on <backspace> yields the following: DEL (translated from <backspace>) runs the command evil-backward-char, which is an interactive compiled Lisp function in `evil-commands.el'. In haskell-mode, however, I get: <backspace> runs the command haskell-indentation-delete-backward-char, which is an interactive compiled Lisp function in `haskell-indentation.el'. The difference I notice is that in the first, we have "DEL (translated from <backspace>)", but in the second, just "<backspace>". From this I gather that evil-mode probably traps the key DEL, but not the key <backspace>. Should evil-mode perhaps trap <backspace> directly as well as DEL? Or is this a bug in haskell-mode, i.e. should haskell-mode be trapping DEL instead of <backspace>? -Keshav

A couple of questions
by Keshav Kini 13 Sep '13

13 Sep '13

Hello, First of all, thank you very much for your great work on evil! I'm really pleasantly surprised at how active your development is :) I'm a vim user who is trying to learn emacs without losing the handy modal editing of vim (as I imagine many others on this list are), and evil seems to be exactly what I need. I have a couple of questions. First, I am wondering if evil-want-C-u-scroll is broken. I have set it to t using M-x customize-group evil-mode, which causes (custom-set-variables '(evil-want-C-u-scroll t)) to appear in my ~/.emacs , but I don't see any difference in the behavior of evil. Is there something else I need to do in order to make C-u call evil-scroll-up (as C-h k C-d tells me that C-d is bound to evil-scroll-down)? Second, I am wondering about the behavior of :q . It seems to me that it behaves more like :qa does in vim. According to vim documentation, :q[uit] should "Quit the current window. Quit Vim if this is the last window.". So I guess it should be similar to kill-buffer in emacs, no? Thanks again! -Keshav

Strange effect when delete, then inserting a region
by Manfred Lotz 31 Mar '13

31 Mar '13

Hi there, Using evil mode I do the following: 1. I mark a couple of lines using V, then delete it using d (which is evil-delete). 2. Now when inserting this anywhere else using p or P I get this: p\310^V^A When I do not delete the original lines, i.e. I do y (evil-yank) then this does not happen. Anybody having an idea what's going wrong? -- Thanks, Manfred

How to replicate the great visual selection search and replace
by Alan Schmitt 30 Mar '13

30 Mar '13

Hello, There is a feature of evil I really like: it's how it's displaying the current matches and what the substitution will be when doing a search and replace on a selected region. Unfortunately I sometimes have to use a machine on which I cannot install evil. I was wondering if such a similar feature existed in emacs, or if it was implemented from scratch in evil. Thanks a lot, Alan

evil-show-marks
by Manfred Lotz 28 Mar '13

Hi there, I tried to list the marks but :marks didn't work. marks is mapped to evil-show-marks which doesn't seem to be implemented anywhere. -- Manfred

[evil-mode] C-[ not being captured
by Marcelo de Moraes Serpa 25 Mar '13

25 Mar '13

Hi list, I'm using Emacs on OSX (GNU Emacs 24.3.1 (x86_64-apple-darwin, NS apple-appkit-1038.36)), with evil-mode. I'm having an issue with the "C-[" combo for ESC. On Emacs 23, it used to work fine, and exit from insert mode correctly when I was using evil. On 24, it just doesn't do anything. Any hints on why it's not working ? Cheers! - Marcelo.

Setting up "jj" to force normal state
by Marcelo de Moraes Serpa 25 Mar '13

25 Mar '13

Hello everyone, I've tried setting up the "jj" key combo to exit from insert mode in evil using key-chord, but it doesn't seem to work. I'm using the following snippet: (key-chord-define evil-normal-state-map "jj" 'evil-force-normal-state) > (key-chord-define evil-visual-state-map "jj" > 'evil-change-to-previous-state) > (key-chord-define evil-insert-state-map "jj" 'evil-normal-state) > (key-chord-define evil-replace-state-map "jj" 'evil-normal-state) Key-chord.el is loaded, and I get no errors when evaluating the piece of code above. However, when I test by entering Evil's INSERT mode and trying to exit it by quickly pressing "j" followed by another "j", it stays at --INSERT--. Any hints appreciated! - Marcelo.

can't use "S" in normal mode with haskell-mode
by Linus Arver 21 Mar '13

21 Mar '13

Hello all, I use emacs-evil with haskell-mode. Whenever I enter the "S" hotkey a new buffer (haskell-mode's "Help" file) is opened on a split window and it gets stuck in <M> state. I can use the "S" hotkey fine when haskell-mode is not active, though. Any pointers? Thanks, -L

bug in evil-default-cursor with function value?
by Óscar Fuentes 20 Mar '13

20 Mar '13

For setting the color and shape of the cursor I wrote this code: (setq evil-default-cursor #'ofv/evil-cursor) (defun ofv/evil-cursor () "Change cursor color according to evil-state." (setq cursor-type (if (eq evil-state 'visual) 'hollow 'box)) (set-cursor-color (case evil-state ('insert "dark orange") ('emacs "sienna") ('visual "white") (otherwise "green")))) The color is correctly updated, but not the shape: apparently it still uses the default shapes (box for normal, bar for insert, etc). Looking at evil-refresh-cursor I see that it ends with (evil-set-cursor default) (evil-set-cursor cursor) The second call to evil-set-cursor seems to override the first one, where the value obtained from evil-default-cursor is used. I see no easy fix for that, because `default' might contain shape and color, or only one of those, or nil (because evil-default-cursor contains a function that does all the job.)

How to unbind TAB in normal mode?
by Óscar Fuentes 20 Mar '13

20 Mar '13

I'll like to use Tab as per the Emacs bindings in normal mode, so tried this: (setq evil-want-C-i-jump nil) (define-key evil-normal-state-map (kbd "TAB") nil) (define-key evil-normal-state-map [tab] nil) No way. C-h k TAB in normal mode still shows: TAB (translated from <tab>) runs the command evil-jump-forward, which is an interactive Lisp function in `evil-commands.el'. It is bound to TAB. (evil-jump-forward &optional COUNT) Any suggestions?
