emacs-pool

emacs-pool is an emacs daemon pool that preloads single-use emacs daemons in the background. It aims to provide an equivalent experience to non-daemon mode emacs but with a faster startup.

emacs-pool consists of two binaries:

• emacs-pool-daemon: Pre-loads emacs daemons in the background. Automatically starts up new daemons, and kills daemons after use. Listens for client connections via unix domain socket.

• emacs-pool-client: Asks emacs-pool-daemon for a new emacs daemon, and then runs emacsclient to connect to it. The emacs daemon will be destroyed after emacsclient is closed.

Building

Requirements:

• A recent installation of Rust with async/await support
• emacs 26.1 (for --fg-daemon flag)

cargo install --path . will install emacs-pool-daemon and emacs-pool-client to your cargo bin directory.

Usage

Link or copy scripts/run.sh to somewhere on your path and use it instead of emacs. The script will automatically start up emacs-pool-daemon in the background if necessary before invoking emacs-pool-client. Edit the script variables at the top to configure socket path and emacs paths.

Notes

• The daemon can be shutdown with killall emacs-pool-daemon when startup with run.sh. Using SIGKILL (-9) would not give the server time to shutdown the emacs daemons, and you would have to do so manually.
