<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

evil, agenda, list of all todo items (basic question)
by Andrew Forrester 08 Jan '14

08 Jan '14

Hi everyone, Question: (background below) I'm using Evil in Emacs Org Mode, and I'm having trouble in trying to do something simple in the agenda. I type ";a" to enter the agenda, then I type "t" to filter my file into just the non-finished todo items, but it doesn't filter and instead gives me some kind of status buffer or something that I can't figure out (see below). I've tried typing various things that it seems to be suggesting, including ("N", "r", "N r"), but it still doesn't do the trick. I've also done some googling and manual searching, without success yet. What am I doing wrong? What I see when I try to filter my file to see a list of non-finished todo items: ================================================== * DONE text * PROJ A title for a multi-step item. :@computer:... * TODO Say hello. * NEXT Buy socks. * Not a todo item. -UU-:----F1 test.org All L1 <N> (Org Ind EvilOrg) -------------------------------------------------------------------- Global list of TODO items of type: ALL Available with `N r': (0)[ALL] ================================================== Background: I'm new to Emacs, Vim, and Org Mode, but I decided I wanted Vim keystrokes and Org Mode for organization. So it looks like my best options are Evil or VimOrganizer. I'm trying Evil right now, but I'm having trouble figuring out how to do basic things. Thanks for any help you can give! -Andrew

Fundamental mode and undo-tree-mode
by Linus Arver 05 Jan '14

05 Jan '14

Hello list, When I open a file with an unrecognized extension, my Emacs opens it in Fundamental mode (which is what I want). I have Evil enabled with (require 'evil) (evil-mode 1) but the file's buffer does not have undo-tree-mode enabled. I have to manually enable it with M-x undo-tree-mode . I tried adding (global-undo-tree-mode) in my ~/.emacs, but I get nothing. I also tried adding (add-hook 'evil-after-load-hook (lambda () (undo-tree-mode) ) ) but it doesn't help. If I set my emacs' default major mode to text-mode, then undo-tree gets enabled and everything works, but I don't want to use this workaround. I also tried deleting all of my ~/.emacs except for these lines (require 'evil) (evil-mode 1) , but I still get the same behavior. Interestingly, the *Messages* buffer has undo-tree-mode enabled with this same configuration. Does anyone have the same issues with Fundamental Mode + Undo Tree Mode when opening a file? -L

Problems with Clipboard History and selections
by Justin Gordon 02 Jan '14

02 Jan '14

The current implementation of x-select-enable-clipboard calls x-select-text for all cursor movement with a selection. This is not the behavior when using non-evil mode. Basically, emacs takes over my clipboard history unless the below patch is done. I'm on a Mac and use Alfred clipboard history. My change below in bold seems to fix this issue. 1. Is this the right thing to do? 2. Is there a contributions info page that explains how to contribute to this project. I'm familiar with github forks and pull requests. Thanks, Justin *(setq x-select-enable-clipboard nil)* (defun evil-visual-update-x-selection (&optional buffer) "Update the X selection with the current visual region." (let ((buf (or buffer (current-buffer)))) (when (buffer-live-p buf) (with-current-buffer buf (when (and (evil-visual-state-p) (fboundp 'x-select-text) (or (not (boundp 'ns-initialized)) (with-no-warnings ns-initialized)) (not (eq evil-visual-selection 'block))) * ;; CHANGE* * ;; ONLY call x-select-text if x-select-enable-clipboard is true* * (if x-select-enable-clipboard* (x-select-text (buffer-substring-no-properties evil-visual-beginning evil-visual-end)))))))) -- Justin Gordon | 808-877-6461 | m: 808-281-7272 www.railsonmaui.com | twitter: @railsonmaui<https://twitter.com/railsonmaui> | sugarranchmaui.com <http://www.sugarranchmaui.com/> | Sugar Ranch Blog<https://www.facebook.com/SugarRanch>
