Windows Terminal version

1.18.3181.0

Windows build number

Microsoft Windows [Version 10.0.22621.2861]

Other Software

Elvish (0.20.0-dev.0.20240108164435-9112eb1ab2f4+official) (latest HEAD)

Steps to reproduce

Run Elvish on Windows, and paste a sufficiently long chunk of text into the shell's prompt, about 1k to 2k characters.

Expected Behavior

The entire pasted content to be received by the shell in one go, matching the behaviour exhibited by the shell on Unix-like environments and WSL2.

Actual Behavior

The pasted content is received by the shell gradually.

(This happens on both Windows Terminal and Alacritty)

I previously reported this to the Elvish repo (elves/elvish#1744), and the discussion pointed that this might be an issue with Windows's ConHost/ConPTY and bracketed pasting. Hopefully this is the right place for the issue :)

Yep this is the right place! It's not an issue with our code however and so I'll close this issue. It's also not really an issue with elvish either and fixing it requires just 1 line change in elvish. I'll comment in the linked elvish issue how to fix this. 😊

@lhecker lhecker closed this as not planned Won't fix, can't repro, duplicate, stale Jan 10, 2024
