Hellyna's: Auto stripping of trailing whitespace characters on write

Auto stripping of trailing whitespace characters on write

With anyone working on patches it's always important we have whitespace stripped before the diff/patch is pushed. Therefore this is what I add in my .vimrc(I use vim).

" automatically remove trailing whitespace before write
function! StripTrailingWhitespace()
    normal mZ
    %s/\s\+$//e
    if line("'Z") != line(".")
        echo "Stripped whitespace\n"
    endif
    normal `Z
endfunction
autocmd BufWritePre COMMIT_EDITMSG,.vimrc,*.js,*.cpp,*.hpp,*.i,*.h,*.c :call StripTrailingWhitespace()

I have this stuff highlighted in vim. just add this to your ~/.vimrc:

let c_space_errors = 1
let c_no_tab_space_error = 1

Interesting snippet that will work well for many projects. However, if you edit a file that *already* has trailing whitespace, you shouldn't remove it in the same commit as other changes.

@Anon75UGYhyT: Exactly. But that's what "git add -i" is for. ;)

Thanks for the tip Hellyna! I use vim and I was looking for something like this, but I never took the time to learn how to write one.
