Wrapped long line copy under tmux

[piec]

First thank you for your work on wezterm which I find great and full of features.

Is your feature request related to a problem? Please describe. When using tmux in wezterm, wezterm interprets long wrapped lines as multiple lines (of terminal width length) instead of a single wrapped line. This means that:

• If I tripple click a particular block of text it will only select a single line (not a issue to me, but it helps to understand the situation). I am not using semantic prompt.
• If I copy/paste a long wrapped line, it will be pasted wrapped as rendered in wezterm.

Triple click in wezterm without tmux - OK: Triple click (or [shift]+triple click if you use tmux with mouse support on) - BAD:

I suppose it's related to how tmux renders these lines on screen and how wezterm interprets them. I have looked for options in tmux to configure its behavior related to newlines but didn't find anything.

Describe the solution you'd like Have the selection and copy-paste work the same when in tmux. Many terminals work as I expected with tmux (triple click and copy/paster): uxterm, gnome-terminal, alacritty.

Describe alternatives you've considered Use tmux copy/paste support with mouse, for example with https://github.com/tmux-plugins/tmux-yank. But it's not always practical.

Additional context

• wezterm uses TERM=xterm-256color
• wezterm 20230712-072601-f4abf8fd
• tmux 3.3a
• Default conf for bash and tmux
• Arch Linux

tmux outputs several disconnected lines, so wezterm doesn't know that they are a single logical line. This will not be solved in wezterm.

Note that wezterm has native UI for tabs and panes and has many of the same features as tmux.

wezterm on windows and Mac with ssh to remote host does this, tmux (on the remote) or no tmux. Yet Windows Terminal or iTerm2 are copy/pasting a single line in the exact same conditions. For me that's a showstopper. I couldn't find how to configure wezterm to copy/paste wrapped line as a single line. That should be the default IMHO.
