How to make vim run "cpplint" after every "save" command?

I wish that each time I ":w" to save a .h/.cpp file in vim, vim will automatically run cpplint to check my format, and change the file if needed.

How to specify this with autocmd?

Thanks.

Solution

  • If you want to use an autocmd for this, you can simply add this to your .vimrc:

    autocmd BufWrite *.cpp :! cppcheck %

    However, I would personally recommend using a syntax checking plugin for this. The very popular vim-syntastic supports cpplint out of the box. You can use the following line to set cpplint as the syntax checker for C++ files. 

    let g:syntastic_cpp_checkers = ['cpplint']

    The advantage of using a plugin is that it will integrate with Vim and highlight where there are issues, rather than just dumping textual output to stdout.

    PS: make sure cpplint is in your $PATH, without it neither approach will work.
