Multi-line paste no longer treated as a single block (splits into multiple inputs)

Description

Description

After upgrading to OpenCodeCLI v1.0.24, pasting a multi-line prompt is no longer accepted as a single input. In prior (pre-v1) versions, the CLI displayed “[pasted # lines]” and processed the entire block atomically. In v1.0.24, the paste fragments—sometimes only the first line runs, sometimes lines execute one by one, and in some cases it spawns multiple sessions.

This looks like a regression or a change in input buffering / bracketed-paste handling. Is there a flag/setting to restore the legacy behavior, or is a new workflow required?

Version

• OpenCodeCLI: 1.0.24

Expected Behavior

• Entire multi-line paste is accepted and queued as a single input, with a “[pasted # lines]” confirmation (legacy behavior).

Actual Behavior

• Paste is fragmented: sometimes only the first line runs; sometimes lines execute one-by-one; in one case it split the block into four separate sessions.

Clipboard Shortcuts (Windows)

• Ctrl+V: not working (no paste occurs).
• Ctrl+Shift+V and Shift+Insert: paste works, but the multi-line content is still split rather than treated as one block.

Environment

• OS: Windows 10 (installed via Scoop)
• Terminals where reproduced: WezTerm v20240203-110809-5046fc22

Workaround

• Bundle all instructions into a .txt file and ask the model to read + execute it. This works but is not optimal.

Additional Notes / Questions

• Was bracketed-paste support removed or gated behind a flag in v1?
• If this is an intentional change, what is the recommended workflow for large multi-line prompts?
• If unintentional, can legacy “[pasted # lines]” behavior be restored or made configurable?

OpenCode version

1.0.24

Steps to reproduce

Steps to Reproduce

1. Launch OpenCodeCLI v1.0.24.
2. Paste a multi-line prompt/snippet (any text with several lines; example below).
3. Observe that the paste is not treated as a single block and may execute line-by-line or split into separate sessions.

This issue might be a duplicate of existing issues. Please check:

• #3343: Cannot paste multiple lines in Windows Terminal and VSCode+Powershell - Similar issue with multi-line paste being split into individual messages on Windows
• #3542: Paste bug - Same issue described: "on windows its gonna paste and press enter every , damn, line" (closed but might be related)
• #3397: opentui: Multi-line paste with Ctrl+Shift+V is pasted as single line - Related multi-line paste issue (though different symptom)
• #3484: Fix TUI paste editor regression - pasted text object not expanding in editor (closed) - Another paste regression issue

The core issue appears to be a regression in bracketed-paste handling specifically affecting Windows users in v1.0.24, where multi-line content is no longer treated as a single atomic input.

Feel free to ignore if none of these address your specific case.

ok looks like our logic was splitting on newline and seeing if it was > 5 lines - this is too naive because one line can be super long. fixing

[thdxr]

although your example text does work for me

[thdxr]

can you try npx/bunx/whatever opencode-ai@dev and see if it's better?

Ran it using pnpm dlx opencode-ai@dev, here I include the video recording

PS: Terminal used is WezTerm (wezterm 20240203-110809-5046fc22)

I'm using Warp, on MacOS and I used "npx opencode-ai@dev" to test it but I still can't paste multiple lines. I get a something like [Pasted ~1 lines] instead.

Isn't that the correct behavior? If you want to paste raw, maybe use Command + Shift + V or Command + Shift + Option + V ?

@thehaseebahmed that's expected behavior it collapses the pastes and expands them again when it is submitted.

If you want to disable this behavior, add the following to your opencode.json:

{
  "$schema": "https://opencode.ai/config.json",
  "experimental": {
    "disable_paste_summary": true
  }
}

@ramhaidar @rekram1-node Thanks! I just updated today and I think the version I was on before, this behavior was not present. I did try Ctrl + Shift + V but that wasn't working for some reason but this help.
