From d00f680c0d2c3210a318d4750f2908cd65d7278a Mon Sep 17 00:00:00 2001 From: Daniel Danner Date: Tue, 18 Nov 2025 21:38:30 +0100 Subject: [PATCH] fix(clipboard): use tmux only in a tmux session #36407 This reverts 2495e7e. That past change meant that we would modify the buffer contents of a tmux session if it exists, even if the current Nvim process wasn't running inside of it. Depending on the tmux configuration, this could even affect the clipboard of an actually attached tmux client, since tmux itself uses OSC 52 to forward buffer writes to attached clients. While autodetection is usually a trade-off and can rarely make everybody happy, this behavior goes counter the principle of least surprise. If really desired, it can be brought back by explicit configuration. --- runtime/autoload/provider/clipboard.vim | 2 +- runtime/doc/news.txt | 1 + 2 files changed, 2 insertions(+), 1 deletion(-) diff --git a/runtime/autoload/provider/clipboard.vim b/runtime/autoload/provider/clipboard.vim index 198c497d48..5952a1768b 100644 --- a/runtime/autoload/provider/clipboard.vim +++ b/runtime/autoload/provider/clipboard.vim @@ -255,7 +255,7 @@ function! provider#clipboard#Executable() abort return s:set_clip() elseif executable('termux-clipboard-set') return s:set_termux() - elseif executable('tmux') && (!empty($TMUX) || 0 == jobwait([jobstart(['tmux', 'list-buffers'])], 2000)[0]) + elseif !empty($TMUX) && executable('tmux') return s:set_tmux() elseif get(get(g:, 'termfeatures', {}), 'osc52') && &clipboard ==# '' " Don't use OSC 52 when 'clipboard' is set.
