with-editor

The hunk feature of magit is great; you can easily stage/unstage not only at the hunk granularity but also arbitrary lines using the selection. Being able to easily do that was something I really missed when I moved from darcs to git. When it comes to magit and TRAMP, definitely the best part is with-editor[1]. This is one of those ingenious "why didn't I think of this?" hacks to let you use your local Emacs as EDITOR on remote machines without having to do SSH port forwarding for emacsclient.

TRAMP reuses ssh connections. It's straightforward to configure OpenSSH to reuse its connection, see e.g. https://en.wikibooks.org/wiki/OpenSSH/Cookbook/Multiplexing and that is what TRAMP does. >Can you make it work with multiple SSH connections to arbitrary servers, without any per-server configuration? Certainly, of course. Depending on your level of hackery, you can: - Make ssh automatically copy an emacsclient wrapper script over which does the correct thing - Use OpenSSH's Unix socket forwarding on each connection to connect emacsclient to your local Emacs server - Use https://github.com/magit/with-editor I've never bothered, though, because I run all my shells on remote hosts via TRAMP within Emacs, so when I am in a shell, I can just use open the remote files through the normal Emacs keybindings, rather than typing "emacsclient fi
