Copypaste mangling in nano

[EvelynSubarrow]

If you try to copy and paste multiple lines within the terminal, you'll find that the lines end up between each other in ways which aren't very helpful. It's possible that this is intended functionality and this is an enhancement ticket, I drew a blank when searching the documentation for this anyway.

Environment (please complete the following information):

• OS: Ubuntu 20.04.2 LTS, under i3wm
• Version: 20210804-100121-b6c6cef8

To Reproduce

Open two instances of wezterm, with nano open in both, and the contents of two files as follows:

File A:

#!/usr/bin/env python3
if __name__=="__main__":

    fizzbuzz = lambda x: "Fizz"*(x and not x%3)+"Buzz"*(x and not x%5) or str(x)
    print([fizzbuzz(n) for n in range(16)])

File B:

We're no strangers to love
You know the rules, and so do I
A full commitment's what I'm thinking of
You wouldn't get this from any other guy

Select the text in file B with the mouse cursor, from the first to the final character, copy the text using the set keyboard shortcut, switch to file A, put the terminal cursor on the blank line, and paste. You'll end up with something like:

#!/usr/bin/env python3
if __name__=="__main__": We're no strangers to love You know the rules, and so do I fizzbuzz = lambda x: "Fizz"*(x and not
x%3)+"Buzz"*(x and not x%5) or str(x) A full commitment's what I'm thinking of print([fizzbuzz(n) for n in range(16)])
You wouldn't get this from any other guy

Configuration

local wezterm = require 'wezterm';
return {
    color_scheme = "Builtin Tango Dark",
    hide_tab_bar_if_only_one_tab = true,
    font = wezterm.font_with_fallback({
        "JetBrains Mono", "Twemoji Mozilla"
    }),
}

Expected behaviour

The text should be intact when pasted, similar to some other terminals. If there's a good reason this behaviour should not be a default, it could be configurable

What version of nano are you using?

[wez]

Relevant background information; nano has historically had problems with paste: https://savannah.gnu.org/bugs/?49176 Nano 4.8 includes support for bracketed paste which should help alleviate those problems (https://savannah.gnu.org/bugs/?40060)

[EvelynSubarrow]

aha, I hadn't considered it might be nano, I'm quite far pre-4.8, I'll see if upgrading resolves this

[EvelynSubarrow]

Tested with my shiny new copy of nano, and can confirm that resolves it, thank you for the pointer!
