Essential Emacs Packages and Modes for Newcomers

When you first venture into the world of Emacs, there are several packages and modes that can significantly enhance your experience and productivity. This guide will introduce you to a list of must-have packages and modes that are crucial to jumpstart your Emacs journey.

Introduction to Emacs Eco-System

Emacs, one of the most versatile text editors, has a rich ecosystem filled with packages and modes that can be customized to suit your specific needs. Whether you are a beginner looking to enhance your coding experience or an advanced user seeking powerful features, this guide will help you find the best tools to fit your workflow.

Key Packages and Modes for Beginners

1. Package Management with package.el

Emacs comes with a built-in package manager called package.el. To enable it in your configuration, simply include the following:

unless package-installed-p
  use-package package
  package-refresh-contents
  package-install 'use-package
(require 'use-package)

This setup helps you easily install and manage other packages, ensuring a smooth and organized editing environment.

2. Simplified Configuration with use-package

use-package is a powerful macro for organizing your Emacs configuration. It simplifies package management and configuration by allowing you to declare packages and their configurations in a clean, readable way. Here is an example configuration for use-package:

use-package ivy
  :ensure t
  :config
  (ivy-mode 1)
use-package counsel
  :ensure t
use-package swiper
  :ensure t

3. Powerful Completion Frameworks with ivy/counsel/swiper

The ivy/counsel/swiper package provides a robust completion and search framework enhancing the built-in functionality. This makes it easier to find files, buffers, and perform other tasks. Here’s how you can set it up:

use-package ivy
  :ensure t
use-package counsel
  :ensure t
use-package swiper
  :ensure t

By enabling these packages, you can streamline your workflow and enhance your editing experience significantly.

4. Git Management with magit

For Git users, magit is an indispensable tool. It provides a powerful interface for managing Git repositories directly within Emacs. To include magit in your setup, follow this configuration:

use-package magit
  :ensure t

5. On-the-Fly Syntax Checking with flycheck

flycheck is a package that provides on-the-fly syntax checking for various programming languages. It helps you catch errors as you type, enhancing your coding experience. Here’s how to include it:

use-package flycheck
  :ensure t
  :init (global-flycheck-mode)

6. In-Buffer Completion with company-mode

company-mode is a highly effective in-buffer completion framework that can speed up coding. It provides suggestions for code completion, making your coding process more efficient. Include it in your setup as follows:

use-package company
  :ensure t
  :init (global-company-mode)

7. Project Management with projectile

projectile is a project management tool that makes navigating and managing projects much easier. It allows you to switch between projects quickly, enhancing your workflow. Here’s how to set it up:

use-package projectile
  :ensure t
  :config (projectile-mode 1)

8. Efficient Note-Taking with org-mode

While built into Emacs, org-mode is incredibly powerful for organizing notes, managing tasks, and even writing documents. Familiarizing yourself with it is highly recommended. Here’s how to include it:

(require 'org)

9. Learning Keybindings with which-key

which-key is a package that displays available keybindings in a popup. This is particularly useful for beginners to learn Emacs keybindings. Here’s how to include it:

use-package which-key
  :ensure t
  :config (which-key-mode)

10. Visualizing Code Structure with rainbow-delimiters

rainbow-delimiters colorizes matching parentheses, brackets, and braces, making it easier to visualize code structure. Here’s how to include it:

use-package rainbow-delimiters
  :ensure t
  :hook (prog-mode . rainbow-delimiters-mode)

11. Bringing Vim-like Editing with evil-mode

If you come from a Vim background or prefer modal editing, evil-mode is the package for you. It brings Vim keybindings and functionality to Emacs. Here’s how to include it:

use-package evil
  :ensure t

12. Alternative Search and Navigational Interface with helm

helm is an alternative to ivy/counsel/swiper for navigation and completion. It provides an intuitive interface for searching and managing files and buffers. Here’s how to include it:

use-package helm
  :ensure t
  :config (helm-mode 1)
