<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

Failing tests
by Sébastien Willmann 05 Nov '12

Hello, After running make test, it seems that some tests fail on my computer (tests results attached). Are the tests wrong or does it mean that there is some compatibility issues? I use emacs 24.1.1 on fedora 17. Thanks, Sébastien Willmann

ggVG doesn't copy the last line of a buffer
by Dan Rosén 31 Oct '12

31 Oct '12

Hi, This is an issue I have: When I have a file which ends with a non-blank line, then ggVG will copy (and select) the entire buffer, but that last line. ggVG$ works, but that is a bit annoying. Is there a way to make G go to the last character of the last line, and not only the last line? Thanks, Dan

DRY way of remapping a key in all relevant modes
by Patrick Brinich-Langlois 24 Sep '12

24 Sep '12

Hi, I've been using Vim with extensive remappings designed for the Colemak keyboard layout (http://colemak.com/pub/vim/colemak.vim) I'm trying to recreate the Vim mappings in Emacs with Evil. What's a good way of remapping a key in all relevant contexts? For example, I want "i" mapped to evil-forward-char in normal, visual, visual block, dired, etc. modes. I want to avoid this: (define-key evil-normal-state-map "i" 'evil-forward-char) (define-key evil-visual-state-map "i" 'evil-forward-char) (define-key whatever-corresponds-to-dired-map "i" 'evil-forward-char) I tried to write some Elisp to do this, but it doesn't work (Wrong type argument): (defun remap-all (char action states) (if states (progn (define-key (car states) char action) (remap-all char action (cdr states))))) (setq states '(evil-normal-state-map evil-visual-state-map)) (remap-all "i" 'evil-forward-char states) Thanks, Patrick

Question regarding evil mode in emacs and xcscope.el
by Maindoor 17 Sep '12

17 Sep '12

Hi, I'm not sure if this is the right mailing list as there is no mention of evil mode in the mail address. If this is the case please correct me. I'd like to start the xcscope results window in insert mode instead of the default normal mode. How do I do this ? None of the below works. Maybe I'm doing it wrong with the mode names. any suggestions ? (setq evil-insert-state-modes (append cscope-list-entry-mode evil-insert-state-modes)) (evil-set-initial-state cscope 'insert) Regards

Why does :q delete the window
by Guido Van Hoecke 03 Sep '12

03 Sep '12

Hi, I usualy have a 2x2 window configuration for my Emacs frame. My evil-version is 0.1 and my emacs is GNU Emacs 24.2.1 (x86_64-apple-darwin, NS apple-appkit-1038.36) of 2012-08-27 on bob.porkrind.org Anybody has an idea why :q or :wq not only gets rid of the buffer, but also of the window? Editing a file in window 2 with following configuration -1- -2- -3- -4- and doing :q in -2- I end up with configuration ---1--- -3- -4- This is rather annoying. Any pointers? TIA, Guido -- No one knows like a woman how to say things that are at once gentle and deep. -- Hugo http://vanhoecke.org ... and go2 places!

How to manage keymaps
by Barry OReilly 03 Sep '12

03 Sep '12

I've put together a guide for managing keymaps in a way that allows one to use much of Emacs in Vim-like ways (ie using short key sequences near home row instead of Control-Shift-Nonsense). It has some of the things I would have liked to know when I first converted to Emacs, but now do and can communicate to the next generation of migrants from Vim. There's also a section on defining an escape key sequence. Both are in the EmacsWiki Evil article. http://www.emacswiki.org/emacs/Evil

Keymap for evil-execute-in-emacs-state
by Barry OReilly 03 Sep '12

03 Sep '12

The key binding for evil-execute-in-emacs-state is currently defined in evil-normal-state-map. However, perhaps it makes more sense to put it in evil-motion-state-map, so as it is available in buffers that start in motion state. For example, the user might want to \b in Buffer Menu, to run the Buffer-menu-bury command.
