VIM的%<变量替换问题

怎么将%<替换成文件名.data？

例如将上面的%<.data替换成下面的文件名.data

用这个命令:

Enter之后的结果:

:call append(line("."), expand('%') . ' and something append')

    %       current file name
    #       alternate file name
    #n      alternate file name n
    <cfile>     file name under the cursor
    <afile>     autocmd file name
    <abuf>      autocmd buffer number (as a String!)
    <amatch>    autocmd matched name
    <sfile>     sourced script file name
    <slnum>     sourced script file line number
    <cword>     word under the cursor
    <cWORD>     WORD under the cursor
    <client>    the {clientid} of the last received
            message |server2client()|

Modifiers:
    :p      expand to full path
    :h      head (last path component removed)
    :t      tail (last path component only)
    :r      root (one extension removed)
    :e      extension only

进入命令行模式

:%s/%<.data/.data/g

我觉得，网上能找到答案的，就不用来这里问了
