This is simple program that watches for clipboard text and proxies it for cases where original selection's window is closed.

To keep program simple it only handles text clipboard.

To avoid breaking stuff when it's proxying capability are not required uses passive mode via Xfixes.

Most clip managers got too much features and dependencies or don't handle clipboard proxying.

So after finding xclipd it was doing most of things i need but it was too intrusive and broke other clipboard mimes, so i decided to "meme" rewrite it to rust and use xfixes selection events.

Almost the same as xclipd but doesn't take ownership of clipboard if original owner is still around.

You will need to setup rust toolchain, try https://rustup.rs/

$ git clone https://github.com/deinferno/ghostclip/
$ cd ghostclip
$ cargo build --release
$ sudo cp target/release/ghostclip /usr/local/bin

Based on implementation: https://github.com/jhunt/xclipd/
