[vim/Linux] 11. NERD Commenter, 주석 단축키 플러그인

NERD Commenter는 단축키로 주석 처리를 할 수 있게 해주는 플러그인입니다.

.vimrc에 Plugin 'scrooloose/nerdcommenter' 을 추가하고 :PluginInstall 을 합시다.

.vimrc에 다음과 같이 추가합니다.

" NERD Commenter
" Add spaces after comment delimiters by default
let g:NERDSpaceDelims = 1
" Use compact syntax for prettified multi-line comments
let g:NERDCompactSexyComs = 1
" Align line-wise comment delimiters flush left instead of following code indentation
let g:NERDDefaultAlign = 'left'
" Set a language to use its alternate delimiters by default
let g:NERDAltDelims_java = 1
" Add your own custom formats or override the defaults
let g:NERDCustomDelimiters = { 'c': { 'left': '/**','right': '*/' } }
" Allow commenting and inverting empty lines (useful when commenting a region)
let g:NERDCommentEmptyLines = 1
" Enable trimming of trailing whitespace when uncommenting
let g:NERDTrimTrailingWhitespace = 1
" customize keymapping
map <Leader>cc <plug>NERDComToggleComment
map <Leader>c<space> <plug>NERDComComment

저는 <leader>c<space>와 <leader>cs를 사용합니다(현재 리더키는 쉼표입니다). ,c<space>를 입력하면 커서가 있는 줄에 주석이 달립니다. Visual mode (v를 누르면 됨)에 진입해서 여러 줄을 선택한 뒤 ,c<space>를 누르면 여러 줄에 주석처리를 할 수 있습니다. 주석을 해제하려면 ,c<space>를 한 번 더 누르면 됩니다.

,cs는 sexy comment라고 불리는 기능인데, 여러 줄을 주석처리 할 때 주석을 예쁘게 달아줍니다.

지금까지 작성한 .vimrc는 다음과 같습니다.
