This small utility copies its stdin to the clipboard on macOS while preventing properly written Clipboard Managers from accessing the copied data. This is essentially a Go version of pbsecret and I only wrote it to experiment with Go and Objective-C.
The purpose of this program is to be used together with CLI Password Managers (like lpass, op or pass) to write automation scripts.
You would generally pipe the output of some CLI Password Manager to snoopy, or run the following command as a test:
$ echo "password" | snoopy
The original Objective-C code was written by Dustin Goldman dusto@goldmans.net for pbsecret.
