rot13 encoding

Bruce Who
Hi,

        Yesterday I found g? command which is used to do rot13 encoding. If we want to encode all buffers we should go to every buffer and do "ggVg?G", I wonder if there is a function which can do rot13 encoding? So we just need to call the function and don't need to switch to every buffer and change cursor position.
               
    Any help would be appreciated!

Best regards,

Hi, Erlend:

        I knew we can use g? in a function or in a command like this:

    :bufdo :normal ggVg?G

    but, the disadvantage of this normal mode command is that it changes the cursor position. After the command is called, the cursor position is at the end of every buffer. I want to keep the cursor position, so I think a function may solve the problem. Any ideas?

        function! Rot13Encode() range
                let l = line(".")
                let c = col(".")
                exe "normal " . a:firstline . "gg"
                normal V
                exe "normal " . a:lastline . "gg"
                normal g?
                call cursor(l,c)
        endfunction

        " ... etc. ...

        bufdo 1,$call Rot13Encode()


Best regards,

fun! KeepCursorRot13()
    let curcol = col('.')
    let currow = row('.')
    normal ggg?G
    call cursor(currow, curcol)
endfun

:bufdo call KeepCursorRot13()


:help col()
:help row()
:help cursor()

HTH,

James
