State: closed
Merged: Yes

Summary

Fixes clipboard image paste not working on Windows when using Ctrl+V (e.g., after capturing a screenshot with Greenshot).

Problem

On Windows, pressing Ctrl+V with an image in the clipboard didn't paste the image because:

  1. The terminal (ConPTY) doesn't properly send image data through bracketed paste events
  2. Clipboard.read() was only called when the paste event text was empty
  3. Windows terminals often send non-empty text or don't fire the paste event at all for clipboard images

Solution

Added explicit keybind handling in onKeyDown (in the prompt component) to:

  • Intercept Ctrl+V before the terminal handles it
  • Call Clipboard.read() directly to check for images in the clipboard
  • If an image is found, paste it using pasteImage() and prevent default
  • If no image is found, let the normal text paste flow continue

Testing

  1. Use Greenshot (or any screenshot tool) to capture a region to clipboard
  2. In OpenCode CLI, press Ctrl+V
  3. The image should now be pasted as [Image 1] in the prompt

Changes

  • packages/opencode/src/cli/cmd/tui/component/prompt/index.tsx: Added keybind check for input_paste in onKeyDown handler
