[linux] [uncrustify] C like languages Format Source

Atom에서 Atom-Beautify때문에 한번 써본적 있는 uncrustifyCLI에서 사용하는 법을 적어놓는다.

Install at linux
sudo apt-get install uncrustify -y  
Install at windows

http://uncrustify.sourceforge.net/ 에서 다운로드 받고 특정위치에 압축을 풀고
해당 경로를 환경변수 path에 설정하면 된다.

config-file

아래의 파일을 uncrustify.cfg 와 같이 만들어 저장하고,

uncrustify -c uncrustify.cfg --replace main.c  

과 같이 사용하면 main.c파일이 코드포맷되어 바뀐다.

보통은 vim을 사용할테니 vim에서 바뀐 파일을 다시 로드하는 법은

:edit! 이다.
