In paredit mode, when I have something like the following:

(function
    (some-call arg arg arg)
    (some-other-call arg))

and insert a ; on the last line it automatically does this

(function
    (some-call arg arg arg)
   ; (some-other-call arg)
    )

to keep the parentheses balanced.

But when I mark the line with nerd-commenter and call evilnc-comment-or-uncomment-lines:

(function
    (some-call arg arg arg)
   ; (some-other-call arg))

When no text is marked, I would like M-; to toggle commenting the current line. Can you help me modify ~/.emacs to achieve this behavior?

I have enabled evil-mode and evil-leader is set to ,. And I have put (evilnc-default-hotkeys) in my configuration and ,ci works well. But the evil usage does not work, for example, ,,, does nothing.

Do I make something wrong?

With the default setup from

(evilnc-default-hotkeys)

pressing M-; does nothing in the following situation (where | is the cursor):

|
(setq some-var nil)

It would be convenient if it started a new comment.

It handles the inverse operation correctly:

;; |
(setq some-var nil)

followed by M-; yields

|
(setq some-var nil)

i am using the emacs 24.3, after i updated evil-nerd-commenter today, this error happened:
"Invalid function: with-eval-after-load"

evilnc-comment-or-uncomment-lines: Symbol's value as variable is void: b

evil 和 evil-nerd-commenter 都是最新版

(evilnc-default-hotkeys) doesn't work anymore, and it prevents a clean initialization on startup when placed in .emacs.

It gives me this error message:

eval-after-load: Symbol's value as variable is void: evilnc-comment-operator

When I try to mark, highlight to end of line, and evil nerd comment out this typedef line, Emacs spews a debugger, the buffer contents are replaced with just the typedef line, and undo does nothing.

Oddly, when I close the buffer and repeat the same mark, highlight to end of line, and evil nerd comment steps, it works the second time.

I found your answer to a question about joining comment lines and removing the comment delimiter. This is functionality I'm pretty sure I had in vim (via regular J, not a separate bind), though I can't remember for sure; perhaps it was some plugin I was using.

In any case, it's very useful functionality that I was surprised to not find in emacs or in any packages that I could find. You seemed to imply that you did it in this package, but I could find no mention of joining functionality.

Or were you simply referring to the method of detecting whether one was in a comment? If so, would you consider adding comment joining functionality to this package? It'd be nice if we could still use J and the comment-joining functionality would only kick-in if we were in a comment, otherwise it would delegate to the regular J evil functionality, instead of having to have yet another separate bind (although perhaps some people would like that as an option).

Hi (my apologies if this is not the right place to ask questions - I can close and reopen in stack overflow if desired),

I'm a vimmer coming over to spacemacs. I used to use nerdcommenter, so i was happy to see this port in emacs, and auto-included in spacemacs.

In vim (let's use javascript as an example), let's pretend I used visual mode to highlight a couple lines. I could use <Leader>cc to comment them with //, or <Leader>cs to do "sexy" comments (wishing for a better name...) where it would surround the highlighted lines with /** */.

Is this possible with evil-nerd-commenter? I can't seem to find anything in the emacs commands to support it.

Thanks very much for any advice/replies.

Hello,

When I select a region using shift-v and comment it using evilnc-comment-or-uncomment-lines, it also comments the line underneath the region.

Doesn't happen with a region selected with v.

error message:
Symbol's function definition is void: org-edit-src-find-region-and-lang

I am using the latest version of emacs and the packages below:

Hello @redguardtoo
Thanks for this great plugin :)

You mention in the README that you have tested it, but I don't see the test suite.
Was wondering where is it? (or do you do it by hand?)

Tested on Emacs 23.4, 24.3, 24.4, 24.5

useful for comment parameters in function definition.

I love using evil-nerd-commenter to toggle the commented/uncommented state of blocks of code! However, when I try to do this in matlab-mode or octave-mode, it just inserts a new blank comment.

How can we tweak these modes to toggle commenting better?

It does work when I comment some line, and it always adds dnl to the begin of the line. However It fails to uncomment, neither # nor dnl of the commented line.

FYI, the minor modes that are activated is as belows:

use emacs api to select region, then call web-mode-comment
after comment I may need uncomment and vice vesa because web-mode "smart" comment api.

Hi,
I received below error message after updating evil-nerd-commenter on melpa recently.

Warning (initialization): An error occurred while loading `/Users/dawu/.emacs.d/init.el':

Symbol's value as variable is void: evilnc-comment-operator

To ensure normal operation, you should investigate and remove the
cause of the error in your initialization file.  Start Emacs with
the `--debug-init' option to view a complete error backtrace.

I think this is related to the compiled byte files under evil-nerd-commenter directory. i.e. evil-nerd-commenter-pkg.elc and evil-nerd-commenter.elc. After manually deleted those two, I don't get the error message anymore.

At first I thought this might be some problem on melpa side, but purcell believes it looks like an upstream issue melpa/melpa#2042.

I use evil-nerd-commenter in emacs-prelude, it worked fine before until I updated my packages via package manager on melpa recently. Anyway to address this problem?

Thanks,

I'm trying to use evil nerd commenter to toggle on comments for the last block of code in my .emacs file. This triggers a debugger error.

Code:

why autoload so many global keybinds and not provide way for configuration .
I use org-mode which had define C-c c for org-capture . it fails when (require evil-nerd-commenter)
so I must modiy evil-nerd-commenter ,by now has no way to config it , can support it ?

Sorry, I had mistaken the functionality of evilnc-comment-or-uncomment-lines.

May I suggest using backslash \ as default leader key in evilnc-hotkey-comment-operator and evilnc-default-hotkeys instead of comma?

I would really like to keep my evil mode the same with default vim key bindings as much as possible. I've also noticed that in vim, neither vim-matchit nor nerdcommenter would overwrite the normal , functionality by default. Maybe it's better not to use , as default leader key for their Emacs equivalence too?

Thanks for your time and patience to import such great modes into Emacs.

I would like evil-nerd-commenter to use double slashes (//) instead of slash-stars (/* ... */) to comment code in c-mode. How can I configure it this way?

Happy new year! :D

and focus is at the beginning of the next un-commented line

Hi, I'm using your package for quite a while now and I like it a lot.
Today I tried the invert-line-by-line option for the first time and it doesn't work as expected.
Example:
if I type "evilnc-comment-operator j" , 3 instead of 2 lines are commented.
It seems like the wrong starting point of the evil-operator range is chosen.

Thanks for your work.

It's frequently used for evaluating lisp expressions (http://www.gnu.org/software/emacs/manual/html_node/emacs/Lisp-Eval.html)

Hi,
Maybe you've encountered this issue before, but I looked everywhere and were not able to find any solution for this.
When I activate org-indent-mode, and I try and comment out code snippet in a file (this is my config file), the whole org-subtree opens up to the parent node, and all its children open.

If I have this:

** Python configuration
#+begin_src emacs-lisp
(setq python-python-command "~/anaconda3/bin/ipython")
(setq py-shell-switch-buffers-on-execute-p t)
(setq py-switch-buffers-on-execute-p t)
(setq python-shell-virtualenv-path "~/anaconda3")
(when (executable-find "ipython")
  (setq python-shell-interpreter "ipython"))
#+end_src

** Anaconda config...

and try to comment a command, I will end up with:

** Python configuration
#+begin_src emacs-lisp
(setq python-python-command "~/anaconda3/bin/ipython")
(setq py-shell-switch-buffers-on-execute-p t)
;; (setq py-switch-buffers-on-execute-p t)
(setq python-shell-virtualenv-path "~/anaconda3")
(when (executable-find "ipython")
  (setq python-shell-interpreter "ipython"))
#+end_src

** Anaconda config
#+begin_src emacs-lisp
(add-hook 'python-mode-hook 'anaconda-mode)
(setq python-shell-virtualenv-path "~/anaconda3")
#+end_src

I tried going through my config file, but were not able to find anything related. If you need more information, let me know.

I'd better separate one screen cast to several one

hello. plugins like vim-commentary and tcomment use the gc as an operator. so i can gcc to toggle a line, gcG to comment to the end of a file, or gcp to comment a paragraph, etc.

i tried adding (setq evilnc-hotkey-comment-operator "gc") to my .emacs but it's not working as expected. a value of "g c" doesn't work either.

am i configuring it wrong or is this not supported? thanks.

Hello!

I'm newish to Emacs, and just rebuilt my configuration using Cask. After installing evil-nerd-commenter I get the following error:

Symbol's value as variable is void: evilnc-comment-operator

My configuration is something like this (for evil):

(require 'evil)
(require 'evil-leader)
(require 'evil-matchit)
(require 'evil-nerd-commenter)
(require 'key-chord)
(evil-mode t)

(evilnc-default-hotkeys)

Which is where the error is triggered. Any tips on how to work through this? I'm not very familiar with Emacs lisp at this point. Thank you for any help in advance!

These commands:

• evilnc-comment-or-uncomment-to-the-line
• evilnc-copy-to-line

would be more convenient if after executing, user get a prompt asking for a line number. The key bindings are the same, but this is more intuitive. The reason is, sometimes user can accidentally trigger the key bindings without a prefix argument, and without a prefix argument, the commands comment or copy from the first line to the current line. This is confusing for new people, and annoying when user forgets to supply a prefix argument.

The number of key strokes is the same:

• Using prefix argument: C-u <number> <key binding for command>
• Using a prompt: <key binding for command> <number> RET

As you can see, it is more explicit and safer for user when they accidentally run the commands.

see https://pay.reddit.com/r/emacs/comments/1kcdq0/evilnerdcommenter_100_released/cbnvj0l

notes:

• how to mark the region between pair is not dependent on 3rd party packages
• different major-modes should have their own rules, for example, c-mode, prefer mark the region between {} excluding "{}", but for lisp, the "()" should be inclusive.
• make it simple, NO setup

Looks like evil-nerd-commenter is looking for web-mode-is-comment, which doesn't exist. In web-mode, you can hit M-; which apparently calls comment-dwim.

no point comment line instead, if you want to comment current line, no need to select anything.

I do sometimes need comment function parameters

investigation:

1. js2-mode and javascript-mode is buggy, need some hack

Hi,

Evilnc is nice! I would love if evilnc support kill and copy lines from the cursor up to a specified line, so we won't have to mark lines anymore.

No body like to press "953,cl to comment to the line 953", it's 6 key press, instead, they want to press to "3,cl" or better "3,ll", "33,ll" will be next 3.

as title

Hi,
the comment-operator opens all org-headlines if I use it in a babel code-block.
Thanks.

When something like this:

<%= form_for @changeset, @action, fn f -> %>
  <%= if @changeset.action do %>
    <div class="alert alert-danger">
      <p>Oops, something went wrong! Please check the errors below:</p>
      <ul>
        <%= for {attr, message} <- f.errors do %>
          <li><%= humanize(attr) %> <%= message %></li>
        <% end %>
      </ul>
    </div>
  <% end %>

  <div class="form-group">
    <%= submit "Submit", class: "btn btn-primary" %>
  </div>
<% end %>

is commented, you get this:

<!-- <%= form_for @changeset, @action, fn f -> %> -->
<!--   <%= if @changeset.action do %> -->
<!--     <div class="alert alert-danger"> -->
<!--       <p>Oops, something went wrong! Please check the errors below:</p> -->
<!--       <ul> -->
<!--         <%= for {attr, message} <- f.errors do %> -->
<!--           <li><%= humanize(attr) %> <%= message %></li> -->
<!--         <% end %> -->
<!--       </ul> -->
<!--     </div> -->
<!--   <% end %> -->

<!--   <div class="form-group"> -->
<!--     <%= submit "Submit", class: "btn btn-primary" %> -->
<!--   </div> -->
<!-- <% end %> -->

However, it doesn't actually comment out the templating tags as they have to be turned to the <%# %> form. One suggestion would be to keep the existing html style formatting as it helps the editor display things properly.

• Open a new buffer in web-mode.
• Enter some text (e.g. test).
• Execute evilnc-comment-or-uncomment-lines.

The result is <!-- test -->.

• Execute evilnc-comment-or-uncomment-lines again.

The result is <!-- <!-- test --> -->. Expected test.

as title

Currently, when I try negative arguments, evilnc-comment-or-uncomment-lines does nothing. It should comments previous line according to the supplied argument.

Other similar functions should support negative argument as well.

that's an extra package to install when I can implement it by myself.

Hi
just discoverd evil-nerd-commenter and loving it.
there is one issue i found where it wont work inside org mode code blocks ie:

+begin_src emacs-lisp results none

CODE HERE

+end_src

any idea why? can this be fixed

kind regards

Z
