irb -r clipboard
>> Clipboard.paste
Error: Can't open display: (null)
=> ""

my recommendation would be to detect if any display is running/if its a ssh shell?
and then just use some local file ~/.clipboard ...

best solution would be to get clipboard from connected user, imo thats what the user would expect

I played around and recognized that it will work if you connect via ssh -X

Can you please try it?

Maybe I should nevertheless provide the ~/.clipboard fallback.

grosser commented

still the same error, the fallback could also be used when e.g. xclip is not found or on solaris/other unknown systems, so there is always some basic functionality

janlelis commented

yep, I'll do that + issue a warning if $VERBOSE is true

btw, can you install xauth on the server an then ssh -Y to it?

This works for me (but I am not 100% sure which packages are needed and what the security risks are)...

grosser commented

works with xauth and -X, include this in the readme :D

janlelis commented

:)

next version will have the fallbacks

Should also note that the server can disable your usage of -X and only accept specific ENV so don't expect 100%.

janlelis commented

done.. maybe we should do a xclip -o when using the x implementation to just check, if it throws an error and fall back to File in that case...

envygeeks commented

If I remember right there should be a DISPLAY env you can test for...I'd have to double check but I believe that's the case.
