Emacs: List The Names Of Every Interactive Command

Di: Ava

The most valuable aspect of Emacs is the ability it gives you to customize your environment and workflow perfectly for whatever it is you want to do. This is the first video in a series where I’ll show you how to build a complete Emacs configuration while also teaching you what you need to know about Emacs Lisp, the language used to configure Emacs. Let’s take a

Creating or altering key bindings in Emacs is an elusive task for new Emacs users, as you’re forced to write elisp. Learn how to create key bindings from scratch, or simply use some of my ready-made templates to get you started. An Emacs Tutorial: Beginner’s Guide to Emacs Once you finish Emacs’s tutorial, you’re left with more questions than answers. In this beginners‘ tutorial to Emacs, I’ll show you how to customize Emacs; how to get around and ask Emacs questions; and how to spot (and avoid) picking up bad habits. You can then give commands interactively. Full terminal emulation is available. Whenever you specify a relative file name for an executable program (either in the cmd argument to one of the above commands, or in other contexts), Emacs searches for the program in the directories specified by the variable exec-path.

¶ GNU/Linux GNU/Linux is the easiest OS for installing and using Emacs. It is available in (pretty much) every Linux distribution’s package manager, typically under the name emacs, so it’s easy to find!

Introduction to the Command Line

For a given command, lets say C-c C-k, how to list the bindings of this key for all modes ? C-h k KEY show bindings only for the current mode. It’s the same for invert commands like C-h f and C-h b. To specify the shell file name used by M-x shell, customize the variable explicit-shell-file-name. If this is nil (the default), Emacs uses the environment variable ESHELL if it exists. Otherwise, it usually uses the variable shell-file-name (see Single Shell Commands); but if the default directory is remote (see Remote Files), it prompts you for the shell file name. See Minibuffers for File

Interactive Codes (GNU Emacs Lisp Reference Manual)If the command was invoked through shift-translation, set the mark and activate the region temporarily, or extend an already active region, before the command is run. If the command was invoked without shift-translation, and the region is temporarily active, deactivate the region before the command is run.

In doom emacs the find-file command shows a list of directories like the attached image. In my custom emacs config find-file only gives me a prompt asking for the directory. How can I get a popup like this in my own config?

Emacs is the advanced, extensible, customizable, self-documenting editor. This manual describes how to edit with Emacs and some of the ways to customize it; it corresponds to GNU Emacs version 27.2.

Due to its versatility, many users find themselves resorting to Emacs constantly, and they open an Emacs session soon after turning their computer on and leave it open for the duration of their computing endeavor. If you plan to have Emacs running for an extended time, it is helpful to run Emacs in the background or another virtual terminal so that the command line becomes

Major Modes (GNU Emacs Manual)25.1 Major Modes Every buffer possesses a major mode, which determines the editing behavior of Emacs while that buffer is current. The mode line normally shows the name of the current major mode, in parentheses (see The Mode Line). The least specialized major mode is called Fundamental mode. This mode has no mode-specific Emacs concepts: windows, frames, files, and buffers Invoking commands with keybindings and with M-x To run the tutorial, start Emacs and type C-h t, that is, Ctrl-h followed by t. All the features described in this tour work in GNU Emacs 23. Some features described weren’t included in previous versions of Emacs but can be installed separately.

26.10 Contents of Directories A directory is a kind of file that contains other files entered under various names. Directories are a feature of the file system. Emacs can list the names of the files in a directory as a Lisp list, or display the names in a buffer using the ls shell command. In the latter case, it can optionally display information about each file, depending on the options

32 Dired, the Directory Editor Dired makes an Emacs buffer containing a listing of a directory, and optionally some of its subdirectories as well. You can use the normal Emacs commands to move around in this buffer, and special Dired commands to operate on the listed files. Dired works with both local and remote directories. Org-mode is one of the most useful tools in Emacs and I use it every day for my agenda, notes, course material, academic paper writing, and so on. Naturally, I need a searching tool to find my org-headings inside the Emacs and navigate/rearrange them. defun (Programming in Emacs Lisp)This definition begins with a parenthesis and the symbol defun, followed by the name of the function. The name of the function is followed by a list that contains the arguments that will be passed to the function. This list is called the argument list. In this example, the list has only one element, the symbol, number. When the function is used,

Not only will Emacs prompt for the name, but Emacs will complete the name if you type enough of it and press . A function with two or more arguments can have information passed to each argument by adding parts to the string that follows interactive.

¶ What will we cover? Today we’re going to talk about the many ways you can interact with files and directories using Emacs Lisp! There are a few different ways to do this with user-facing Emacs functionality (find-file, eshell, Dired, etc), but at some point you will want to automate some of these tasks with Emacs Lisp code. 21.2.3 Examples of Using interactive Here are some examples of interactive: This book, written by Protesilaos Stavrou, also known as ‘Prot’, provides a big picture view of the Emacs Lisp programming language.

commands, even though strictly speaking the key is bound to a command. Usually, we state the name of the command which really does the work in parentheses after mentioning the key that runs it. For example, we Completion Provide completion. TAB, SPC, and RET perform name completion because the argument is read using completing-read (see Completion). ? displays a list of possible completions. Existing Require the name of an existing object. An invalid name is not accepted; the commands to exit the minibuffer do not exit if the current input is not valid. Default A default

Most people that use Emacs are programmers – that’s a fact! Most programmers have to deal with relational databases – that’s also a fact! Programmers often interact with the database they have to use via some dedicated client – be it a console or a GUI one. One fairly little known fact about Emacs is that it features a mode that wraps around terminal database Emacs concepts: windows, frames, files, and buffers Invoking commands with keybindings and with M-x To run the tutorial, start Emacs and type C-h t, that is, Ctrl-h followed by t. All the features described in this tour work in GNU Emacs 23. Some features described weren’t included in previous versions of Emacs but can be installed separately. Using Interactive (GNU Emacs Lisp Reference Manual)Warning: the argument values should not include any data types that can’t be printed and then read. Some facilities save command-history in a file to be read in the subsequent sessions; if a command’s arguments contain a data type that prints using ‘ #<> ’ syntax, those facilities won’t work. There are, however, a few exceptions

That symbol names a keymap with single-letter key bindings for common Emacs file commands, for instance c is bound to copy-file. This means that if you are in the minibuffer after running a command that prompts for a file, such as find-file or rename-file, you can copy a file by running embark-act and then pressing c. 21.6.5 Reading File Names The high-level completion functions read-file-name, read-directory-name, and read-shell-command are designed to read file names, directory names, and shell commands, respectively. They provide special features, including automatic insertion of the default directory. Function: read-file-name prompt &optional directory default require-match If the key sequence that invoked the command has n events that are lists, the n th ‘ e ’ provides the n th such event. Events that are not lists, such as function keys and ASCII characters, do not count where ‘ e ’ is concerned. ‘ f ’ A file name of an existing file (see File Names). The default directory is default-directory.

12 Help Emacs provides a wide variety of help commands, all accessible through the prefix key C-h (or, equivalently, the function key F1). These help commands are described in the following sections. You can also type C-h C-h to view a list of help commands (help-for-help). You can scroll the list with SPC and DEL, then type the help command
