open a file for editing in an already running nvim
nvclient connect to the existing nvim instance by looking for the
environment variables NVIM_LISTEN_ADDRESS, if the NVIM_LISTEN_ADDRESS
is not found when nvclient start, it will start a new nvim instance.
If NVIM_LISTEN_ADDRESS is already set when nvim start, nvim will use its vaule
to create the socket, otherwise NVIM_LISTEN_ADDRESS is only can be found
in the nvim terminal. In this case, you can check the value by
:echo $NVIM_LISTEN_ADDRESS
you can do the trick by setting the NVIM_LISTEN_ADDRESS in your shell's .dotfile,
so everytime you open a file with nvcllient, it will be sent to the same nvim
instance, but beware any new nvim instance will overwrite the socket file.
For tmux user, nvclient read the tmux environment for NVIM_LISTEN_ADDRESS
if it is running in tmux, but you have to set the tmux update-environment
correctly in .tmux.conf to make it work.
Example:
set -g update-environment "SSH_ASKPASS WINDOWID XAUTHORITY NVIM_LISTEN_ADDRESS"
