How to yank & paste in nmap?

[AdrienLemaire]

On firefox/chrome, I use yomichan to see japanese translations.
Since it has no support for webkit2gtk, I'm trying to find an alternative solution:

Manual operation:

• select word and Y (yank/copy text)
• t to open in new tab
• jisho<tab> to find a previous jisho search, then remove search part
• C-v twice to paste the yanked text in the search url
• Enter

Automated operation:

shortcut-add j=https://jisho.org/search/$0
nnoremap <C-J> Y :tabopen j <C-v><C-v><CR>

What I'm trying to do is auto yank and open jisho page with selected text. But my map isn't working.

Example: Selecting text '大幅' and pressing Ctrl-j

Expected:

• A new tab opens with https://jisho.org/search/大幅

What happens:

• 2 tabs open, each with https://jisho.org/search/

Looks like the <C-v> part of the nnoremap doesn't work. How would you do it @fanglingsu ?

@AdrienLemaire I do also not understand why <C-V> does not work but you could use <C-R>" instead which writes the last yanked register.
:nnoremap <C-J> Y:tabopen j <C-R>"<CR>

@AdrienLemaire I though a bit about the <C-V> this does not work because it is no vimb command. The first <C-V> is a command which stops key processing logic of vimb so the second CTRL-V is interpreted by webkit or GTK to past the clipboard. If the :nnormap is applied there is no logic which would turn <C-V> into a keyevent that could be used by webkit. So it does not work.

@fanglingsu lovely, I'm almost there :)

shortcut-add j=https://jisho.org/search/$0
nnoremap <C-J> Y :tabopen j <C-R>"<CR>

It now opens the correct page, but still open 2 tabs instead of one.
I can't figure out why 2 tabs are being open here.

If I use nnoremap <C-J> Y :tabopen j <C-R>" then highlight text and press C-j-Enter, it works as expected.

@AdrienLemaire That's strange! I can reproduce this and I can't guess why this should happen. I'll have to debug this.

[fanglingsu]

@AdrienLemaire For me this works if I strip the space between the yank Y and the :tabopen.

nnoremap <C-J> Y:tabopen j <C-R>"<CR>

But I'm far away from getting the reason for this behaviour.

Thanks for figuring out the trick! This is perfect now :)

The issue seems to be related to #546.

@AdrienLemaire I think it is now solved.
