  1. # System clipboard integration
  2. #
  3. # This file has support for doing system clipboard copy and paste operations
  4. # from the command line in a generic cross-platform fashion.
  5. #
  6. # This is uses essentially the same heuristic as neovim, with the additional
  7. # special support for Cygwin.
  8. # See: https://github.com/neovim/neovim/blob/e682d799fa3cf2e80a02d00c6ea874599d58f0e7/runtime/autoload/provider/clipboard.vim#L55-L121

  10. # - pbcopy, pbpaste (macOS)
  11. # - cygwin (Windows running Cygwin)
  12. # - wl-copy, wl-paste (if $WAYLAND_DISPLAY is set)
  13. # - xsel (if $DISPLAY is set)
  14. # - xclip (if $DISPLAY is set)
  15. # - lemonade (for SSH) https://github.com/pocke/lemonade
  16. # - doitclient (for SSH) http://www.chiark.greenend.org.uk/~sgtatham/doit/
  17. # - win32yank (Windows)
  18. # - tmux (if $TMUX is set)
  19. #
  20. # Defines two functions, clipcopy and clippaste, based on the detected platform.
  21. ##
  22. #
  23. # clipcopy - Copy data to clipboard
  24. #
  25. # Usage:
  26. #
  27. # <command> | clipcopy - copies stdin to clipboard
  28. #
  29. # clipcopy <file> - copies a file's contents to clipboard
  30. #
  31. ##
  32. #
  33. # clippaste - "Paste" data from clipboard to stdout
  34. #
  35. # Usage:
  36. #
  37. # clippaste - writes clipboard's contents to stdout
  38. #
  39. # clippaste | <command> - pastes contents and pipes it to another process
  40. #
  41. # clippaste > <file> - paste contents to a file
  42. #
  43. # Examples:
  44. #
  45. # # Pipe to another process
  46. # clippaste | grep foo
  47. #
  48. # # Paste to a file
  49. # clippaste > file.txt
