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

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

<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

Including Evil in GNU ELPA
by Stefan Monnier 19 Jul '14

19 Jul '14

I remember asking this a few years ago, but somehow I can't seem to find the answer. So here it is again: I think it would be great to include Evil in the GNU ELPA archive. Would Evil's maintainers be interested in doing so? If yes, then please get in touch with me, so we can work out the details (which mostly have to do with copyright paperwork, since we have the same policy for GNU ELPA as for Emacs, to make it easy to move code between the two).

evil: work on support for ]p, [p (adjust indent on paste)
by Johann Klähn 02 Jul '14

02 Jul '14

Hi there, I would like to work on a patch to add support for ]p and [p to evil. I have some working code (see below) to adjust the indent after a call to evil-paste-after / evil-paste-before, but I would appreciate tips on how to integrate this with existing evil code (especially so that ]p will be a single undo step, that evil-paste-pop still works, …). All the best, Johann (defun get-common-indent-in-region (start end) (setq end (copy-marker end)) (unwind-protect (let (indentation) (save-excursion (goto-char start) (or (bolp) (forward-line 1)) (while (< (point) end) (skip-chars-forward " \t") (setq indentation (cons (current-column) indentation)) (forward-line 1))) (apply #'min indentation)) (move-marker end nil))) (defun my-evil-adjust-indent-afer-paste () (interactive) (unless (memq last-command '(evil-paste-after evil-paste-before)) (error "Previous command was not a line-wise evil-paste: %s" last-command)) (let* ((start (evil-get-marker ?\[)) (end (evil-get-marker ?\])) (common (get-common-indent-in-region start end)) (this (save-excursion (cond ((eq last-command 'evil-paste-before) (goto-char end) (forward-line 1)) (t (goto-char start) (forward-line -1))) (skip-chars-forward " \t") (current-column)))) (indent-rigidly start end (- this common))))

Vim Movement
by Gulshan Singh 02 Jul '14

02 Jul '14

Hi, I'm wondering how if it's possible emulate Vim word movement using the same M-f and M-b bindings in Emacs? I've currently done this: (global-set-key (kbd "M-f") 'evil-forward-word-begin) (global-set-key (kbd "M-b") 'evil-backward-word-end) That's decent, but I think that actual Vim movement uses the evil-forward-word-end and evil-backward-word-begin methods as well. How can I do this?

binding to "cp" without breaking "c"
by Justin M. Keyes 02 Jul '14

02 Jul '14

Hi, I'm trying to bind a command to the "unused namespace" that happens to start with "c". By "unused namespace" I mean things like "cp" or "co" for which there is no valid text object or motion. In Vim, you can bind "cow" and it does not affect the behavior of "cdw", "ciw", etc, because "o" is not defined as a text object. For example, in unimpaired.vim[1], "cow" toggles word-wrap. I would like to do this in emacs evil, so I tried: (define-key evil-normal-state-map (kbd "c o w") 'toggle-truncate-lines) It reports "eval-region: Key sequence c p w starts with non-prefix key c". But I don't want to unbind "c" because then I can't use the evil-change operator. I tried defining a custom operator, but after looking at the evil source code I couldn't figure out how to hook into evil-change to preserve its behavior while listening for "o" and then routing it somewhere else. It seems like I'm missing something, I would think this is a common task, but I haven't found any posts that address this. Thanks for evil, it's superb!
