vim + COPY + mac over SSH

Question

I access a sever over ssh on which I run vim for editing files. When I try to yank text from vim into an editor locally on my mac (lion) either with y OR "+y it does not work. I end up with the text I copied last locally. It does work if I just use p within vim alright.

Here's an update on the solution #2 from romainl. It creates and alias of the ssh command and launches the remotecopyserver if it's not running and installs the remotecopy(rclip) in the remote server. In short, you don't have to do anything except paste the code snippet below into your bash_profile.

######################## For SSH Remote Copy #########################
export LC_SETUP_RC='command -v rclip >/dev/null 2>&1 || { echo "executing"; mkdir -p /usr/local/bin; if [ ! -f /usr/local/bin/rclip ];then wget https://raw.githubusercontent.com/justone/remotecopy/master/remotecopy -P /usr/local/bin/; ln -s /usr/local/bin/remotecopy /usr/local/bin/rclip; chmod +x /usr/local/bin/remotecopy; fi; if [[ \":\$PATH:\" == *\"/usr/local/bin:\"* ]]; then export PATH=/usr/local/bin:$PATH; fi } > /var/log/rclip.log 2>&1 || echo "Some error occured in setting up rclip. check /var/log/rclip.log"'

ssh_function() {
count="`ps -eaf | grep remotecopyserver | grep -v grep | wc -l`";
if [ "$count" -eq "0" ]; then 
   mkdir -p $HOME/bin;
   if [ ! -f $HOME/bin/remotecopyserver ]; then 
      wget https://raw.githubusercontent.com/justone/remotecopy/master/remotecopyserver -P $HOME/bin;
      chmod +x $HOME/bin/remotecopyserver;
   fi;
   nohup $HOME/bin/remotecopyserver & 
fi;
ssh_cmd=`which ssh`
PARAMS=""
for PARAM in "$@"
do
  PARAMS="${PARAMS} \"${PARAM}\""
done
bash -c "ssh ${PARAMS} -R 12345:localhost:12345 -t 'echo \$LC_SETUP_RC | sudo bash; bash -l'"
}
alias ssho=`which ssh`
alias ssh=ssh_function
alias ssh2=ssh_function

vssh_function() {
ssh_config=`vagrant ssh-config`;
if [ "$?" -eq "1" ]; then
echo "Problem with Vagrant config. run 'vagrant ssh-config' to debug"
return 1
fi
PORT=`echo "$ssh_config" | grep Port | grep -o "[0-9]\+"`; 
ID_FILE=`echo "$ssh_config" | grep IdentityFile | awk '{print $2}'`
ssh2 -q -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no -o PasswordAuthentication=no -i $ID_FILE vagrant@localhost -p $PORT "$@"
}
alias vssh=vssh_function

Once the alias is activated, you can normally use ssh and whenever you need to copy to local clipboard from vim, use

:w !rclip 

to copy the whole file to clipboard

:'<,'> !rclip

to copy selected lines from visual mode. You have to press "Cmd+V" or "Ctrl+V" whenever it asks for the secret key.

Bonus

For those who work on Vagrant, there's a wrapper vssh which will execute vagrant ssh but also launches and install the necessary components.

Caveats

The alias wraps the ssh command and there might be some unexpected issues. ssho is available if you need to execute ssh without the whole remotecopyserver thing. Alternatively, you can use the alias ssh2 and keep the ssh command as it is.

Answer 2

My go-to solution is to edit the file with vim from your local machine via scp.

:e scp://[e-mail]//path/to/document

This keeps your buffer local and makes it easy to copy to your local clipboard.

The other advantage is that you get to use your local vim setup (.vimrc settings, plugins, etc.)

Answer 3

My first answer on stackoverflow, but I feel it's a cool (albeit tiny) trick and it's worth posting. So here's what I do :

cat <filename>

When the text is printed onto the terminal, I select all the text with my mouse (the mouse scroll works since we're on the terminal window). Then copy that text with Cmd+C and paste into my local text editor.

The only flaw with this trick is that it's impractical to use if your files are tens of thousands of lines long since selecting all the lines with your mouse would be a task in itself. But for a file of ~2k lines it works well.
