Clipboards in general don't work the same across platforms. In particular, there are platforms like Linux that don't have a single unified clipboard, they have several different clipboards with different APIs supported by different classes of apps. How would you propose to deal with that? |

Based on my (non-exhaustive) search I agree that this looks surprisingly difficult in Linux without relying on large 3rd party gui toolkits. The Mac on the other hand looks like it might be possible. |

Relying on third-party toolkits would be OK if we only support them if they're already installed to support apps that use them. But that's not what I was talking about: Linux standard GUIs have multiple, incompatible clipboards, at the same time. In general, each GUI or non-G UI framework has a different clipboard. Linux itself doesn't have a clipboard at all.
Different approaches:
Fortunately R3 is primarily made for application building or integration. The standalone interpreter is just one such application, meant to assist in running one-off utility scripts, and maybe to be distributed in operating systems; it doesn't have to support a clipboard if the system doesn't have one. |

On Mac: there are pbcopy and pbpaste that provides comprehensive access to the Mac's clipboard. I wrote a wrapper in R2 for them: http://reb4.me/r/clipboard
I know it's a dependency, but as OS X is a stable, consistent platform it might be considered a safe one... |

If the wrapper approach is acceptable for OS X then xclip could be used in a similar way to pbcopy/pbpaste. This approach is dependant on call/ouput and call/input. Not an ideal solution, but would be acceptable for me |

With the wrapper approach, the clipboard:// port will stop working when CALL is blocked for security. So that might work as a workaround, but not as a solution. |

As far as I know, on Linux there are basically two clipboards,
a) where you can mark text, and paste it with middle mouse button b) cut/copy -> paste like in windows I'd say, rebol only needs to handle option b), which seems to be consistent with freedesktop.org. http://standards.freedesktop.org/clipboards-spec/clipboards-latest.txt |
