Commenting sexily omits the next line in C files

[adam8157]

test.c

comments <--- place your cursor at this line
void foo();

Comment the first line sexily, <Leader>cs, then the void foo(); line disappears.

[alerque]

I cannot replicate this. Are you sure you don't have something else going on? I copied your example exactly and it works fine for me. Have you tried for example disabling all other plugins?

[adam8157]

Found it, the configuration triggers this is: set foldmethod=syntax

Could you please take a try?

[alerque]

Nope, foldmethod=syntax is the default for me anyway so that's already what I was testing with.

What version of VIM/Neovim are you using? Do you have any fold related plugins?

[adam8157]

My minimal reproduced vimrc:

set nocompatible

set foldmethod=syntax

" Plugin manager
if empty(glob('~/.vim/autoload/plug.vim'))
        silent !curl -fLo ~/.vim/autoload/plug.vim --create-dirs
                \ https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim
        autocmd VimEnter * PlugInstall | source $MYVIMRC
endif

call plug#begin('~/.vim/bundle')

Plug 'scrooloose/nerdcommenter'

call plug#end()

[alerque]

Confirmed. Also in Neovim.

Incidentally my problem reproducing this was I have this set by default:

let g:NERDCompactSexyComs = 1

As a temporary workaround, the sexy comments work if you start from visual mode, so Shift+V before your <leader>cs should get you there.

PRs welcome if anybody wants to tackle fixing this.
