Configuring Emacs on Arch Linux

After installing Emacs, you can start customizing it to fit your needs. The configuration file for Emacs is usually located in ~/.emacs.d/init.el. If it doesn’t exist, you can create it using your preferred text editor, like Vim or Nano.

Add your custom configurations to the init.el file. For example, you can change the default theme by adding the following line:

(load-theme 'tango-dark t)

Save the file and restart Emacs to apply your changes.

Installing Packages

Emacs has a vast ecosystem of packages that extend its functionality. To install packages, you can use the built-in package manager called package.el. First, you need to configure the package repositories in your init.el file.

Add the following lines to your init.el:

(require 'package)
(setq package-archives '(("gnu" . "https://elpa.gnu.org/packages/")
                         ("melpa" . "https://melpa.org/packages/")))
(package-initialize)

Save the file and restart Emacs. Now you can install packages using the M-x package-install command followed by the package name. For example, to install the popular Magit Git interface for Emacs, run:

M-x package-install RET magit RET
