# System clipboard integration # # This file has support for doing system clipboard copy and paste operations # from the command line in a generic cross-platform fashion. # # This is uses essentially the same heuristic as neovim, with the additional # special support for Cygwin. # See: https://github.com/neovim/neovim/blob/e682d799fa3cf2e80a02d00c6ea874599d58f0e7/runtime/autoload/provider/clipboard.vim#L55-L121 # # - pbcopy, pbpaste (macOS) # - cygwin (Windows running Cygwin) # - wl-copy, wl-paste (if $WAYLAND_DISPLAY is set) # - xsel (if $DISPLAY is set) # - xclip (if $DISPLAY is set) # - lemonade (for SSH) https://github.com/pocke/lemonade # - doitclient (for SSH) http://www.chiark.greenend.org.uk/~sgtatham/doit/ # - win32yank (Windows) # - tmux (if $TMUX is set) # # Defines two functions, clipcopy and clippaste, based on the detected platform. ## # # clipcopy - Copy data to clipboard # # Usage: # # <command> | clipcopy - copies stdin to clipboard # # clipcopy <file> - copies a file's contents to clipboard # ## # # clippaste - "Paste" data from clipboard to stdout # # Usage: # # clippaste - writes clipboard's contents to stdout # # clippaste | <command> - pastes contents and pipes it to another process # # clippaste > <file> - paste contents to a file # # Examples: # # # Pipe to another process # clippaste | grep foo # # # Paste to a file # clippaste > file.txt # function detect-clipboard() { emulate -L zsh if [[ "${OSTYPE}" == darwin* ]] && (( ${+commands[pbcopy]} )) && (( ${+commands[pbpaste]} )); then function clipcopy() { cat "${1:-/dev/stdin}" | pbcopy; } function clippaste() { pbpaste; } elif [[ "${OSTYPE}" == (cygwin|msys)* ]]; then function clipcopy() { cat "${1:-/dev/stdin}" > /dev/clipboard; } function clippaste() { cat /dev/clipboard; } elif (( $+commands[clip.exe] )) && (( $+commands[powershell.exe] )); then function clipcopy() { cat "${1:-/dev/stdin}" | clip.exe; } function clippaste() { powershell.exe -noprofile -command Get-Clipboard; } elif [ -n "${WAYLAND_DISPLAY:-}" ] && (( ${+commands[wl-copy]} )) && (( ${+commands[wl-paste]} )); then function clipcopy() { cat "${1:-/dev/stdin}" | wl-copy &>/dev/null &|; } function clippaste() { wl-paste --no-newline; } elif [ -n "${DISPLAY:-}" ] && (( ${+commands[xsel]} )); then function clipcopy() { cat "${1:-/dev/stdin}" | xsel --clipboard --input; } function clippaste() { xsel --clipboard --output; } elif [ -n "${DISPLAY:-}" ] && (( ${+commands[xclip]} )); then function clipcopy() { cat "${1:-/dev/stdin}" | xclip -selection clipboard -in &>/dev/null &|; } function clippaste() { xclip -out -selection clipboard; } elif (( ${+commands[lemonade]} )); then function clipcopy() { cat "${1:-/dev/stdin}" | lemonade copy; } function clippaste() { lemonade paste; } elif (( ${+commands[doitclient]} )); then function clipcopy() { cat "${1:-/dev/stdin}" | doitclient wclip; } function clippaste() { doitclient wclip -r; } elif (( ${+commands[win32yank]} )); then function clipcopy() { cat "${1:-/dev/stdin}" | win32yank -i; } function clippaste() { win32yank -o; } elif [[ $OSTYPE == linux-android* ]] && (( $+commands[termux-clipboard-set] )); then function clipcopy() { cat "${1:-/dev/stdin}" | termux-clipboard-set; } function clippaste() { termux-clipboard-get; } elif [ -n "${TMUX:-}" ] && (( ${+commands[tmux]} )); then function clipcopy() { tmux load-buffer "${1:--}"; } function clippaste() { tmux save-buffer -; } else function _retry_clipboard_detection_or_fail() { local clipcmd="${1}"; shift if detect-clipboard; then "${clipcmd}" "$@" else print "${clipcmd}: Platform $OSTYPE not supported or xclip/xsel not installed" >&2 return 1 fi } function clipcopy() { _retry_clipboard_detection_or_fail clipcopy "$@"; } function clippaste() { _retry_clipboard_detection_or_fail clippaste "$@"; } return 1 fi } function clipcopy clippaste { unfunction clipcopy clippaste detect-clipboard || true # let one retry "$0" "$@" }
