This is something I've always wondered to know but was a wee bit afraid to ask:
how do the different X11 clip and paste boards interact with the other
cutbuffers (etc)?
One reason I use xterms for so much of my command line tinkering is how double
clicking selection works (full paths, for instance) and copies the selected
content at once to a clipboard or cutbuffer (CLIPBOARD?). Even before I found
myself using mouses without 3 proper buttons I defined a shortcut (that can be
made with 1 or 2 hands) to paste that content back into the terminal ("Meta
<KeyPress>Left: insert-selection(CLIPBOARD,CUT_BUFFER0)").
With XQuartz and the X11.app from MacPorts I find myself configuring the server
to have sync enabled, but from the other options I activate only "update
PRIMARY when Pasteboard changes". With all other combinations I tried I find
that I lose the contents of the CLIPBOARD, and that doubleclicking also no
longer copies to it.
For xterm work this compromise works well enough because I can still use
pbpaste and pbcopy, and the Copy item in the Edit menu. I actually like that
this gives me 2 clipboards that don't (usually) interfere.
It's less than ideal when I start doing things in GTk-based applications,
applications using Qt5's xcb platform plugin ("qt5-x11") or any other X11
application that aims to provide a "modern" copy/paste experience.
I'll admit that I never taken the trouble to master X11's clipboard and
cutbuffer or its clipboard managers in detail (read: hardly at all). Is there a
setting where I could have a somewhat better integration, but where at least
copying to the CLIPBOARD (through double-click) continues to work (and ideally,
the OS X clipboard doesn't automatically overwrite the CLIPBOARD contents when
I hit Command-C somewhere in a Cocoa app)?
/confused
R.
PS: if the terminology wasn't already confusing enough, the X11 preferences
dialog makes it a step worse by suggesting they're personalities with a will of
their own ("Update [the?!] Pasteboard when [the?!] CLIPBOARD changes") ;)
