A minimal, pure-Vimscript plugin to quickly (un)comment lines or blocks of code in Vim/Neovim.

• Toggle comments on the current line or a visual selection with a single command.
• Automatically uses the correct comment string for supported languages.
• Indentation-preserving: comments are inserted after leading whitespace.
• Pure Vimscript; no dependencies.

Use your favorite plugin manager. Example for vim-plug:

Plug 'josstei/vim-easycomment'

Reload and run :PlugInstall.

• :EasyComment
  • In normal mode: Comments/uncomments the current line.
  • In visual mode: Comments/uncomments the selected block.

For convenience, map it to a key in your vimrc:

" Toggle comment for the current line
nnoremap <leader>c :EasyComment<CR>
" Toggle comment for selection
vnoremap <leader>c :EasyComment<CR>

• The plugin detects the filetype and uses the appropriate comment string.
• If all non-blank lines in the range are already commented, they’ll be uncommented; otherwise, they’ll be commented.
• Comments are applied after leading whitespace, preserving code indentation.

Out-of-the-box support for:

• Vim (")
• Shell (#)
• C/C++/Java/Scala (//)

Given this C code:

int main() {
    printf("Hello world\n");
}

Visually select the lines and run :EasyComment (or use your mapping):

// int main() {
//     printf("Hello world\n");
// }

Run again to uncomment.
