I am trying to synchronize the screen buffer and the primary selection
using the .screenrc and xclip. That's why I added this lines to my
# set the second mark, write to the screen-exchange
# file, and use xsel to synchronize the paste buffer
# with the X selection.
bindkey -m > eval "stuff ' '" writebuf 'exec sh -c "xclip /tmp/screen-exchange"'
# Write from the X buffer in screen
#bind < eval "exec sh -c 'xsel > /tmp/screen-exchange'" readbuf "stuff '^a]'"
bind < eval "exec sh -c 'xclip -o > /tmp/screen-exchange'" readbuf 'paste .'
This doesn't work, actually some tests based of the structure :
`bindkey -m […] 'exec sh -c "cat /tmp/screen-exchange > tmp"'
make me think that my screen-exchange is not readable while the command
is running. The file `tmp' is created but nothing is written into it.
Once the command is done though, a `cat /tmp/screen-exchange' gives me
the right content.
