![]() ![]() The value of suchĪ hook is a list of functions the functions are called with noĪrguments and their values are completely ignored. Most of these variables have names ending with ‘ -hook’. The following is a list of some hook variables that let you provideįunctions to be called from within Emacs on suitable occasions. Emacs supports a client/server mode where new files are opened in a running instance of Emacs.Next: Index, Previous: Standard Keymaps, Up: Emacs Lisp Appendix H Standard Hooks This saves you from having to load configuration and packages for every new file you open. This involves two configuration steps: using EmacsClient to open files, and running the Emacs server. This page focuses on how to launch the server at startup, a.k.a. This feature was introduced in Emacs 23.1. ![]() In Emacs 26.1+, you can force the daemon to run in the foreground: emacs -fg-daemon Daemon mode starts Emacs loading the user’s standard init files, but headless. Systemd is the supported method of running applications at startup on most Linux distributions. The following configuration file rvice will be included in the standard Emacs installation as of 26.1. All you need to do is copy this to ~/.config/systemd/user/rvice. Save it as and then install it: systemctl daemon-reload Instead, you can use this unit file: ĭescription=Emacs: the extensible, self-documenting text editorĮxecStart=/usr/bin/emacs -daemon -user %uĮxecStop=/usr/bin/emacsclient -eval "( progn (setq kill-emacs-hook 'nil) (kill-emacs))" ĮxecStop=/usr/bin/emacsclient -eval "(kill-emacs)"Įnable the unit by running: systemctl enable -user emacsĬentOS 7 does not support -user configurations for systemd. There are other ways to launch emacs -daemon depending on your requirements. One easy way to start the Emacs daemon is via “Settings > Session and Startup > Application Autostart”. You can also place an init script to place in /etc/init.d/emacsd. Gentoo includes support for running Emacs as a daemon in the app-emacs/emacs-daemon package. emerge app-emacs/emacs-daemonĮvery user who wants to connect to an Emacs server must have an own instance of the daemonized Emacs. The init script automatically determines the user by its name, so you create a symbolic link (do not copy the script, or you will miss eventual updates!) in your /etc/init.d directory: ln -s emacs /etc/init.d/emacs. This may be added to the boot sequence (and will run under the user’s privileges) rc-update add emacs. username defaultįurther customizations can be done through the /etc/conf.d/emacs file, which is extensively commented. You may also create individual /etc/conf.d/emacs. username files for “multiplexed” user configuration. To restart the daemon after changing the user configuration, run systemctl -user emacs restart Just add the relevant configuration option as described in the manual. This can then be installed in ~/Library/LaunchAgents and loaded via: launchctl load -w ~/Library/LaunchAgents/įor further instructions see Microsoft Windows Applications/Emacs.app/Contents/MacOS/Emacs The easiest solution is to use a tool like Lingon to create the plist file or can create one manually like this: If you’re running Emacs 23 or higher, you can run Emacs Daemon via macOS’s launchd. You can run emacs -daemon by creating a shortcut file or. See EmacsMsWindowsIntegration for details. The simplest way to stop the emacs daemon from within emacs is to use the kill-emacs or save-buffers-kill-emacs commands. "Save buffers, Quit, and Shutdown (kill) server"įrom outside of emacs this can be achieved using emacsclient, using the -e execute command: emacsclient -e '(kill-emacs)' define function to shutdown emacs server instance Here is a more advanced function will ask if you want to save any modified buffers, quit your session, and shutdown the associated emacs server instance. This will shutdown the daemon immediately with out prompting or saving files. emacs file then use the command: emacsclient -e '(client-save-kill-emacs)' If you would like emacs to prompt if there are unsaved buffers or existing clients/frames, you can add the following functions to your. The display on which the new frame should be opened can optionally be specified.
