心的距離

常用vim的話，或多或少會不小在行末多按了幾個空白，或是在檔尾多了幾個空行。作者Vigil寫了一個去除這些東西的function:

" Remove trailing whitespace when writing a buffer, but not for diff files.
" From: Vigil 
function RemoveTrailingWhitespace()
    if &ft != "diff"
        let b:curcol = col(".")
        let b:curline = line(".")
        silent! %s/\s\+$//
        silent! %s/\(\s*\n\)\+\%$//
        call cursor(b:curline, b:curcol)
    endif
endfunction
autocmd BufWritePre * call RemoveTrailingWhitespace()

將這個function加入/etc/vim/vimrc即可。試用了一下，真不錯~感謝Vigil.
