The problem is solved

My purpose is that: I use vim to edit my m-file and debug it in Matlab. There is no easy-to-use interface plugin between vim and Matlab in Win10. So I just edit m-file in vim and run it in Matlab. Sometimes these m-files may be in different directories, so this function can help me to find them quickly.

My system is Win10, and I use gvim.

In vim, I know pwd and cwd in command mode can get the current directory.

And :let g:myvars=expand('%:p:h') to pass the directory to vim script variable.

I also know :! some_cmd_command to execute the cmd command in vim.

I want to implement such a function, that is, let vim open the file manager of the current path, How should I do? Thanks a lot.

  • @statox I need a file explorer to call other programs on my computer. :Explorer is useful to help me edit the files, but it's too difficult for it to startup other programs.

  • Sorry I deleted my first comment just before you answered. I hadn't understood you were talking about the OS's file explorer but it's clear now :)

I use following to open directory where current file is and select it if possible:

"" Open explorer where current file is located
"" Only for win for now.
func! File_manager() abort
    " Windows only for now
    if has("win32")
        if exists("b:netrw_curdir")
            let path = substitute(b:netrw_curdir, "/", "\\", "g")
        elseif expand("%:p") == ""
            let path = expand("%:p:h")
        else
            let path = expand("%:p")
        endif
        silent exe '!start explorer.exe /select,' .. path
    else
        echomsg "Not yet implemented!"
    endif
endfunc

nnoremap <silent> gof :call File_manager()<CR>

The thing you might be interested in is silent exe '!start explorer.exe /select,' .. path which starts explorer and selects the path provided.

Since your command contains a dynamic element (IOW it's not made up entirely of static strings) you'll need to build it with :execute.

Assuming 'shell' and 'shellcmdflag' have the defaults for win32 (cmd.exe and /c, respectively) then this will work:

exe '!c:\windows\explorer.exe ' . expand("%:p:h")

If c:\windows is already in your PATH envvar then you can leave off c:\windows\.

Prepend silent to the above and the extra console window that pops up will be dismissed automatically.

Simply !start %:p:h should be enough.

However, normall you'd better make use of some builtin "file explorer" plugin. Be it standard netrw or something else. There's rarely a benefit in spawning a full-featured Windows Explorer window.

  • There is a benefit for sure. For example I run asciidoc->pdf conversion and then would like to send pdf file. So I open file explorer from within vim and copy&paste&email&whatever.

  • @MaximKim I said "rarely", not "never". Also, all this could be done within Vim too.

If you are using gvim, you can simply type :browse e in command mode
you will have a mini-file explorer opened with current directory
