vim 实现 linux 多行快速标准注释

不多说了，直接上动图：

上代码：

function! CommentBlock()
    " 获取Visual模式选中的起始和结束行号
    let old_start_line = line("'<")
    let old_end_line = line("'>")

    call append(old_end_line, '')
    call append(old_start_line - 1, '')

    let start_line = old_start_line
    let end_line = old_end_line + 2
    execute "normal! " . start_line . "GV" . end_line . "G"

    " 变量i用于循环
    let i = start_line
    " 循环处理每一行
    while i <= end_line
        " 如果是第一行
        if i == start_line
            execute i . 's/^/\/\*/'
        " 如果是最后一行
        elseif i == end_line
            execute i . 's/^/\ *\//'
        " 其他行
        else
            execute i . 's/^/\ * /'
        endif
        let i += 1
    endwhile
endfunction

function! CallFunctionsAB()
    ""call AddLinesBeforeAndAfter()
    ""call AddLinesAndReselect()
    call CommentBlock()
endfunction

"" 在Visual模式下，把 'gcm' 映射到上面定义的函数
vnoremap gcn :<C-u>call CallFunctionsAB()<CR>
