Ghostty shows pwd/lock indicator when using Chafa, is it a Chafa issue?

Chafa version 1.14.5 (Homebrew)
Ghostty 1.0.0
MacOS 15.2 (24C101)

When using Chafa with the Ghostty terminal app, Ghostty shows the lock icon and security info that it normally shows at a password prompt or at secure text entry.

From the Ghostty developer:
[mitchellh]

This is based on the heuristic we use to detect password input. I don't think there's a way for us to fix this because that's the same heuristic used by iTerm and others to enable this feature. I would recommend reporting to Chafa to try to ease up on their ioctls here.

Hi, thanks for bringing this up. It should probably be filed as an issue, though. Do you know which ioctl mitchellh is referring to? Does passing --polite on help?

Edit: When tcsetattr() is used to turn off echo, ghostty interprets it to mean there's a password prompt. You can indeed work around it by passing --polite on. I'll change it to emit a control sequence instead, which does not trigger the heuristic.

That's great, --polite on is working well to suppress the password issue. Thank you!
