Emacs can be started with the following X-related switches: -name name You probably want to run it as a background process so that you can still use your original window. If you run Emacs under X Windows, it creates its own window to be displayed. Insert contents of file into the current buffer.Īdd directory to the list of directories where Emacs searches for Lisp files.Įmacs is designed to work well with the X Window System. You must use -l and -f options to specify files to execute and functions to call. The editor sends messages to standard error. The following options are useful when running Emacs as a batch editor: -batchĮdit in batch mode. The following options are lisp-oriented (these options are processed in the order encountered): -f function, You can then use the emacsclient command to connect to the server.ĭisplay Emacs version information and exit. Start Emacs as a daemon, enabling the Emacs server and disconnecting from the terminal. This must be the first argument specified in the command line. Use specified file as the terminal instead of using stdin/stdout. This is useful for debugging problems in the init file.

Also, skips any processing of X Windows resources.ĭo not display a splash screen during startup.Įnable the Emacs Lisp debugger during the processing of the user init file ~/.emacs. Similar to " -q -no-site-file -no-spash". This applies only to the next file specified. Go to the line specified by number (do not insert a space between the " +" sign and the number). The same as specifying file directly as an argument. This documentation covers GNU Emacs, which includes special packages to handle mail reading ( RMail) and mail sending ( Mail) outline editing ( Outline) compiling ( Compile) running sub- shells within Emacs windows ( Shell) running a Lisp read-eval-print loop ( Lisp-Interaction-Mode), automated psychotherapy (seriously. "Help Apropos" ( Ctrl-h a) helps you find a command given its functionality, "Help Character" ( Ctrl-h c) describes a given character's effect, and "Help Function" ( Ctrl-h f) describes a given Lisp function specified by name. "Help Tutorial" ( Ctrl-h t) starts an interactive tutorial which can teach beginners the fundamentals of Emacs in a few minutes.

Getting help from within EmacsĮmacs has an extensive built-in help facility, but it assumes that you know how to manipulate Emacs windows and buffers. Writing an extension is programming, but non-programmers can use it afterwards. Most of the editing commands in Emacs are written in Lisp the few exceptions could be written in Lisp but use C instead for efficiency. Existing commands can even be redefined in the middle of an editing session, without having to restart Emacs. New commands are programs written in the Lisp language, which are run by Emacs's own Lisp interpreter. See Customization.Įmacs is extensible in that you can go beyond simple customization and create entirely new commands. To use another example, you can rebind the basic cursor motion commands (up, down, left and right) to any keys on the keyboard that you find comfortable. For instance, if you use a programming language where comments start with ' ', you can tell the Emacs comment manipulation commands to use those strings (see Comments). Emacs editing commands operate in terms of characters, words, lines, sentences, paragraphs, and pages, and expressions and comments in various programming languages.Įmacs is called "self-documenting" because at any time you can use special commands, known as help commands, to find out what your options are, or to find out what any command does, or to find all the commands that pertain to a given topic.Įmacs is customizable in that you can easily alter its behavior in simple ways. It can control subprocesses, indent programs automatically, show multiple files at once, and more. It incorporates over 2000 commands, which can be extended using Emacs Lisp, and automated by user-created macros.Įmacs can do much more than simple insertion and deletion of text. Emacs DescriptionĮmacs is a highly extensible, extremely customizable text editor originally written for the PDP-10 by Richard Stallman in the 1970s.
