Surgot's Emacs Config

• Reference: https://www.melpa.org/

By default, Emacs contains a limited number of package choices. This is why we need Melpa. It's a package repository for Emacs.

MELPA is an ELPA-compatible package repository that contains an enormous number of useful Emacs packages.

Think of it like the VSCode Plugin Marketplace (eww).

(require 'package)
(setq package-enable-at-startup nil)

(add-to-list 'package-archives
	     '("melpa" . "https://melpa.org/packages/"))
(package-initialize)

• Reference: https://jwiegley.github.io/use-package

The use-package macro allows you to isolate package configuration in your .emacs file in a way that is both performance-oriented and, well, tidy.

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

• Disable dialog boxes: This setting disables the display of dialog boxes, such as confirmation or warning pop-ups, in Emacs. It allows for a smoother and uninterrupted workflow.

  (setq use-dialog-box nil)
  

• Disable file dialogs: This setting disables the use of file selection dialogs in Emacs. Instead, Emacs will rely on command-line or programmatic methods for file operations.

  (setq use-file-dialog nil)
  

• Disable backup files: By setting this variable to `nil`, Emacs will not create backup files. This helps to avoid cluttering the file system with unnecessary backup copies.

  (setq make-backup-files nil)
  

• Disable auto-save: Auto-save automatically saves buffer contents periodically in case of unexpected Emacs or system crashes. However, if you prefer to disable this feature, you can set this variable to `nil`.

  (setq auto-save-default nil)
  

• Hide menu bar: This setting hides the menu bar in Emacs, providing more vertical space for your text and reducing visual distractions.

  (menu-bar-mode -1)
  

• Hide tool bar: This setting hides the tool bar, which contains various icons and shortcuts, in Emacs. It further maximizes the available space for editing and reduces clutter.

  (tool-bar-mode -1)
  

• Hide fringes: Fringes are the narrow areas on the left and right sides of the Emacs window. By disabling them, you can utilize the full width of the window for your text.

  (fringe-mode -1)
  

• Hide scroll bar: Emacs provides a scroll bar for navigating through the buffer. If you prefer a more minimalistic interface, you can hide the scroll bar with this setting.

  (scroll-bar-mode -1)
  

• Enable subword navigation: Subword navigation allows moving the cursor through CamelCase or snake_case words more intelligently. This setting enables subword navigation globally in Emacs.

  (global-subword-mode 1)
  

• Use y-or-n-p for prompts: By default, Emacs prompts for user confirmation using 'yes' or 'no.' This setting changes it to use 'y' or 'n' for shorter and faster responses.

  (defalias 'yes-or-no-p 'y-or-n-p)
  

The ef-themes package is an Emacs package that provides a collection of visually appealing themes for Emacs. It enhances the visual experience of Emacs by offering different color schemes and styles that can be applied to the editor.

I love JetBrains Mono. Best for programming. Using it since 2018. Make sure to install it in your system. I use Arch, so I run sudo pacman -S ttf-jetbrains-mono.

(add-to-list 'default-frame-alist
	     '(font . "JetBrains Mono-14"))

Hungry Delete is a minor-mode that causes deletion to delete all whitespace in the direction you are deleting. Works exactly like c-hungry-delete-mode, which is where the code was from. This just packages it up to be easier to use in other modes.

(use-package hungry-delete
  :ensure t
  :defer t
  :config (global-hungry-delete-mode))

After pressing M-x, Emacs users see a prompt below; this prompt allows us to run any command within Emacs. This is what I loved about Emacs when I was learning it first. Almost anything, any functionality, any program, everything is a function, and I can access that function by just pressing M-x. But memorizing all these commands is hard, also typing it. Emacs does provide tab completion, but it sucks. So we are gonna pull up the Emacs magic and install some packages to make it better.

Centaur Tabs is an Emacs package that enhances the tab bar functionality, providing a more visually appealing and user-friendly way to manage multiple open buffers (files) within the editor.

The "emacs-lsp" project is a collection of Emacs packages and tools that implement the Language Server Protocol (LSP) in Emacs. LSP is a standardized communication protocol that enables integration with language servers, which are external programs providing advanced code analysis and language-specific features.

The goal of the "emacs-lsp" project is to enhance the Emacs text editor and turn it into a powerful Integrated Development Environment (IDE) by leveraging the capabilities of language servers. These packages provide language-specific features such as autocompletion, real-time error checking, code navigation, and more. By adhering to the LSP, developers can use a consistent approach across various programming languages, streamlining their workflow and improving productivity.

The project offers a diverse range of packages, each tailored to specific programming languages and their corresponding language servers. This initiative fosters an integrated and standardized environment for Emacs users, enabling them to efficiently code in different languages and benefit from advanced language-specific tooling within their favorite text editor. The "emacs-lsp" project is a valuable resource for developers seeking a robust and unified coding experience in Emacs.

Now, we will configure language server protocol and other settings for each, languages I work on, one by one.

I can't use git without Magit. Magit is a complete text-based user interface to Git. It fills the glaring gap between the Git command-line interface and various GUIs, letting you perform trivial as well as elaborate version control tasks with just a couple of mnemonic key presses. Magit looks like a prettified version of what you get after running a few Git commands but in Magit every bit of visible information is also actionable to an extent that goes far beyond what any Git GUI provides and it takes care of automatically refreshing this output when it becomes outdated. In the background Magit just runs Git commands and if you wish you can see what exactly is being run, making it possible for you to learn the git command-line by using Magit. I ❤ Magit.
