That library isn't going to support Wayland any time soon, and requiring CGO isn't ideal IMO. See this bug, https://github.com/golang-design/clipboard/issues/6 How about this PR? https://github.com/ramonvermeulen/whosthere/pull/29 It switches to using github.com/dece2183/go-clipboard, which supports Mac, Windows, Linux (X11 + Wayland) and Android.

I've been working on a LAN discovery tool with a Terminal User Interface (TUI) written entirely in Go. It's called Whosthere, and it's designed to help you explore devices on your local network without requiring elevated privileges. It works by combining several discovery methods: - mDNS and SSDP scanning - ARP cache reading (after triggering ARP resolution via TCP/UDP sweeps) - OUI lookups to identify device manufacturers It also includes: - A fast, keyboard-driven TUI (powered by tview) - An optional built-in port scanner - Daemon mode with a simple HTTP API to fetch devices - Configurable theming and behavior via a YAML config file Why I built it: Mainly to learn, I've been programming in Go for about a year now and wanted to combine learning Go with learning more about networking in one single project. I've always been a big fan of T

UI applications like lazygit, k9s, and dive. And then the idea came to build a TUI application that shows devices on your LAN. I am by no means a networking expert, but it was fun to figure out how ARP works, and discovery protocols such as mDNS and SSDP. Example usage: --- # install via HomeBrew brew tap ramonvermeulen/whosthere brew install whosthere # or with go install go install github.com/ramonvermeulen/whosthere@latest # run as TUI whosthere # run as daemon whosthere daemon --port 8080 --- I'd love to hear your feedback, if you have ideas for additional features or improvements that is highly appreciated! Current platform support is Linux and MacOS.
