feat(osc52): support tmux clipboard writes via OSC 52#21
Merged
Conversation
Registers an OSC 52 handler in xterm.js so tmux copy-mode (with set-clipboard on + terminal-features clipboard) can write to the Windows system clipboard. Routes through Electron's clipboard module via IPC rather than navigator.clipboard, which requires a user-gesture context that PTY data callbacks don't have.

Summary
clipboardmodule via IPC rather thannavigator.clipboard, which requires a user-gesture context that PTY data callbacks don't haveclipboard:write-textIPC channel in main process and exposes it via preloadHow it works
When tmux has
set-clipboard on(provided bytmux-sensibleby default), it emits\x1b]52;c;<base64>\x07to the outer terminal after each copy. wmux now handles that sequence and writes the decoded text to the Windows clipboard.Testing
printf '\033]52;c;dGVzdA==\007'should writetestto clipboardNo tmux config changes are required —
tmux-sensiblealready enables the necessary settings.🤖 Generated with Claude Code
