Can you use emacsclient on a remote computer?
You cannot use emacsclient to connect to an Emacs instance running on a remote computer. This client-server concept is related to (local) processes, not network nodes. However, you can use various network technologies to log in to the remote computer, attach to an emacs server running there and display the emacsclient’s screen locally.
How to connect to a running instance of Emacs?
Simply replace every place you’d run emacs with this command instead. The emacsclient program will connect to a running instance of Emacs if it exists. -c tells Emacs to open the file in a new frame, which is optional. Specifying -a=”” tells emacsclient to start an instance of emacs if it cannot find one already running.
What does emacsclient do as a default editor?
EmacsClient allows one to open a file for editing in an already running Emacs. Because it doesn’t start a new Emacs instance at each invocation, you can set up EmacsClient as the default editor, e.g. in the environment variable EDITOR or VISUAL.
Can you connect emacsclient to a server via TCP?
As some people pointed out, emacsclient actually does have an option to connect to the server via TCP. However, emacsclient was never meant to be used remotely, the TCP socket option is required for compatibility with non-UNIX systems (i.e. operating systems where UNIX domain sockets are not available, like Windows).
How to do remote forwarding in Emacs server?
Here is one way to accomplish that with SSH’s Remote Forwarding of UNIX Domain Sockets, Emacs’ TRAMP, and a little Ruby. The Emacs Server provides emacsclient (1), a small companion utility that signals a running Emacs to load a file for editing.
Is there a remote listening socket in Emacs?
You can forward a remote listening socket, connecting it to a local one, like the one used by the Emacs Server and emacsclient. The only wrinkle is that the Emacs Server protocol, as observed, doesn’t have any notion of local or remote machines; it is built on UNIX Domain Sockets, a host-based Inter-Process Communication mechanism.
