netclip is a TCP server that listens for copy/paste requests. When client comes in and sends non-empty request, e.g. beep, server will put beep into clipboard. Likewise, when client sends an empty string, server will get text from clipboard and send it back to client.

There is also a client that mirrors the interface of xclip.

Both sides are configured via environment variable NETCLIP_ADDR. By default it's :2547.

To get netclip and xclip:

$ go get github.com/Perlence/netclip/...

Start netclip:

$ netclip &
