vim paste function not woking properly in tmux

[atomwh]

About enviroment: OS: ubuntu 22.04 tmux version: 3.2a (and I also tried latest 3.4, it doesn't work neither) vim version: 8.2.3995

when I am trying to paste something into vim in Insert Mode, I got something weired

1. paste "install", it will become Nstall
2. paste "helloworld", it will become "\nWorld"
3. paste "stormteststr", it will become "Tormteststr"
4. Exsiting content is "123456", when I paste with content "issue"(in insert mode at the end of line using shift+insert), it will become "1ssue23456"
5. Exsiting content is "123456", when I paste with content "And helloworld", it will become "123456nd helloworld"

Even if in normal mode when I want to search something, after input "/", I press shift+insert, what I expected is that the text will show following the "/", and then press "enter" I can search the text. But what I got is that the text directly paste into the file content

I have tried things below:

1. clear .vimrc, issue still exists
2. clear some content of .tmux.conf, issue solved

Hello @atomwh 👋

How are you pasting? This is more than likely unrelated to Oh my tmux!

[atomwh]

Hello

Thanks for your reply

How are you pasting?

I am using shift-insert and mouse right click, both have the issue. My terminal application is xshell

This is more than likely unrelated to Oh my tmux!

Indeed, my first thought was that it was a problem with vim, but I cleared all the custom configurations in vimrc, and the issue still existed. Then I tried to operate directly in the ssh terminal without opening tmux, and pasting works normally, so I suspected that it was a issue with tmux. I also tried to remove .tmux.conf and .tmux.conf.local(installedd following the guide of this repository) in $HOME directory, and pasting works normally. And as I wrote in the issue, when I cleared some part of the .tmux.conf(line 156 to the end), pasting could work normally.

Your tmux config was great, if I have to remove some part of .tmux.conf, some function lost like status bar. So I raised this issue hoping you can help to solve it, thank you.

What's the value of TERM when you're inside tmux and using Oh my tmux!?

[atomwh]

What's the value of TERM when you're inside tmux and using Oh my tmux!?

it was tmux-256color, and in ssh terminal it was xterm.

I triedexport TERM=xterm, pasting got working normally. Any suggestion for TERM setting?

Thanks

[gpakosz]

TERM being set to tmux-256color means that the computer where tmux runs supports that description.

However you mentioned xshell, which I don't know, but seems to be a terminal emulator + ssh client that runs on Windows. And I believe xshell doesn't support tmux-256color.

I don't know if xshell supports the equivalent of adding this line to ~/.ssh/config when the client is running on Linux or macOS

SetEnv TERM=xterm-256color

Something else you can do is, on the server side, uncomment this line from your .local customization file

set -g default-terminal "screen-256color" #!important

[gpakosz]

From within a tmux pane, can you please also share the output of the env command? (Redact as necessary)

[atomwh]

Thanks for your advices about TERM setting.

set -g default-terminal "screen-256color" #!important

After adding this line to .tmux.conf.local, it works, the TERM variable turn into screen-256color and pasting works well.

Thank you :-)

Looking at the output of env, unfortunately there's nothing that could help detect xshell
