How to copy from Vim to system clipboard using wayland and without compiled vim `+clipboard` feature flag

Question

I cannot copy into the + or * register.

:echo has('clipboard') from within Vim returns 0 meaning I don't have that feature flag, I don't want to recompile.

I'm running wayland so I cannot use X11 based solutions

Answer 1

I had trouble finding resources so here is what ended up working by adding in ~/.vimrc.

nnoremap <C-@> :call system("wl-copy", @")<CR>

wl-copy is a Command-line copy/paste utilities for Wayland and it will copy the piped content you give it to system clipboard.

What mapping above achieves is

1. Activate the mapping with Ctrl + @. or choose any convenient key combo
   • nnoremap <C-@>

2. take the contents of the " register,

   • denoted by the @" argument

3. and pipe contents of @" as an argument to the system wl-copy function

   • shown by :call system("wl-copy", @").

Alternatively

Assuming you only want to copy line sections of the file, do shift+v to go into visual mode and only highlight the lines I want to copy. Then do.

:'<,'>w !wl-copy

where

• '<,'> - means you used visual mode to select a range (you don't type this)
• w !{cmd} - write the range to the stdin of cmd, see more at :help w_c

You can map that with

xnoremap <silent> <C-@> :w !wl-copy<CR><CR>

• xnoremap: mapping will work in visual mode only
• <silent>: mapping which will not be echoed on the command line
• <C-@>: desired key combination
• :w !{cmd}: write the range to the stdin of cmd
• <CR><CR>: two enters are needed otherwise command line waits for another command
