How to “copy to clipboard” in vim of Bash on Windows?

Question

I used to use \"+y to copy text to system\'s clipboard, but it doesn\'t work in vim of Bash on Windows.

Answer 1

Below are mappings

• in normal mode cy, cyy and cY (=Clipboard Yank) that copy, respectively, the given text object, line(s), rest of the line from the cursor position to the clipboard, and
• in visual mode Y that copies the visual selection to the clipboard,

independent of whether Vim is started in WSL or not.

nnoremap                    cy                   "+y
nnoremap                    (mgu)   m`_
onoremap                    (gu)        g_
nnoremap                    (ggg)   g``
nmap              cyy                  '(mgu)cy' . v:count1 . '(gu)' . '(ggg)'
nmap                            cY                   cy(gu)

xnoremap Y  "+y

if has('unix') && executable('clip.exe')
    " From :help map-operator
    function! SendToClip(type, ...) abort
        if a:0
            " Visual mode
            normal! gv"+y
        elseif a:type ==# 'line'
            normal! '[V']"+y
        elseif a:type ==# 'char'
            normal! `[v`]"+y
        endif

        call system('clip.exe', @+)
    endfunction

    nnoremap  cy            :set operatorfunc=SendToClipg@
    xnoremap  Y             :call SendToClip(visualmode(),1)
endif
