[vim/Linux] 8. UltiSnip과 vim-snippets

Ultisnip과 vim-snippets은 if, for, while 혹은 switch case같이 패턴이 정해져있는 코드들을 자동으로 입력하도록 도와주는 플러그인입니다. Ultisnip은 저장되어 있는 키워드를 입력한 뒤 Tab을 누르면 키워드에 맞는 코드를 자동으로 완성합니다. 키워드는 vim-snippets이 보관하고 있습니다.

예를 들면, C에서 inc를 입력하고 Tab을 누르면 #include <stdio.h>을 자동으로 입력합니다. 이 상태에서 다른 헤더파일 이름을 입력하면 stdio.h가 지워지면서 새롭게 입력이 됩니다.

main을 입력하고 Tab을 누르면 main함수를 자동으로 완성합니다.

switch도 문제없습니다.

.vimrc에 Plugin 'SirVer/ultisnips' 과 Plugin 'honza/vim-snippets'을 추가하고 :PluginInstall을 합시다.

.vimrc에 다음과 같이 추가합니다.

" UltiSnips
let g:UltiSnipsExpandTrigger="<tab>"
let g:UltiSnipsJumpForwardTrigger="<tab>"
let g:UltiSnipsJumpBackwardTrigger="<s-tab>"
let g:UltiSnipsEditSplit="vertical"

쉽게 입력할 수 있도록 미리 저장되어 있는 코드들을 snippet이라고 부릅니다. snippet은 ~/.vim/bundle/vim-snippets/snippets/ 디렉토리에 저장되어 있습니다. 여기 있는 파일들을 수정하면 본인만의 snippet을 만들어 사용할 수 있습니다.

~/.vim/bundle/vim-snippets/snippets/c.snippets

지금까지 설정한 .vimrc는 다음과 같습니다.
