The minimal-emacs.d project is a customizable Emacs base that provides better Emacs defaults and optimized startup, intended to serve as a solid foundation for a vanilla Emacs configuration.
Creating minimal-emacs.d (init.el and early-init.el) involved extensive research and testing to find the best parameters and optimizations for an Emacs init file. The concept behind minimal-emacs.d is to provide a clean, bloat-free, optimized base.
By default, only essential features are enabled, providing a minimal base that is optimized. From there, users are encouraged to consult this README.md to customize and extend the configuration based on their specific needs.
The author is using minimal-emacs.d as his early-init.el and init.el. He is using 146 packages and his Emacs configuration starts in 0.22 seconds:
A user commented on Reddit that after switching to minimal-emacs.d, their configuration execution time decreased from 3 seconds to just 1 second by simply replacing their init.el and early-init.el files with those from the project. Please send me your feedback and I'll add it to this README.md file.
(The optimizations in minimal-emacs.d significantly contribute to speeding up Emacs startup. Additional factors include deferring package loading when not necessary on startup by using :defer t with use-package, and byte-compiling and native-compiling all .el files. The author also regularly uses M-x list-timers and M-x describe-mode for each file type to ensure only essential modes and timers are active, which helps optimize Emacs' performance.)

Execute the following command to clone this repository into ~/.emacs.d:
git clone https://github.com/jamescherti/minimal-emacs.d ~/.emacs.d
To install minimal-emacs.d in a non-default directory, use the --init-directory Emacs option to specify your desired configuration path. For example, to install minimal-emacs.d in ~/.minimal-emacs.d/, follow these steps:
-
Clone the repository into
~/.minimal-emacs.d/using:git clone https://github.com/jamescherti/minimal-emacs.d ~/.minimal-emacs.d -
Start Emacs with the new configuration directory:
emacs --init-directory ~/.minimal-emacs.d/
To keep your Emacs configuration up to date, you can pull the latest changes from the repository. Run the following command in your terminal:
git -C ~/.emacs.d pull
The init.el and early-init.el files should never be modified directly because they are intended to be managed by Git during an update.
The minimal-emacs.d init files support additional customization files that are loaded at different stages of the Emacs startup process. These files allow you to further customize the initialization sequence:
-
~/.emacs.d/pre-init.el: This file is loaded beforeinit.el. Use it to set up variables or configurations that need to be available early in the initialization process but afterearly-init.el. -
~/.emacs.d/post-init.el: This file is loaded afterinit.el. It is useful for additional configurations or package setups that depend on the configurations ininit.el. -
~/.emacs.d/pre-early-init.el: This file is loaded beforeearly-init.el. Use it for configurations that need to be set even earlier in the startup sequence, typically affecting the initial setup of the Emacs environment. -
~/.emacs.d/post-early-init.el: This file is loaded afterearly-init.elbut beforeinit.el. It is useful for setting up configurations that depend on the early initialization but need to be set before the main initialization begins.
Always begin your pre-init.el, post-init.el, post-early-init.el, and pre-early-init.el files with the following header to prevent them from being byte-compiled and to activate lexical binding:
;;; FILENAME.el --- DESCRIPTION -*- no-byte-compile: t; lexical-binding: t; -*-(Replace FILENAME.el with the actual name and DESCRIPTION with a brief description of its purpose.)
Note: Enabling the tool-bar, menu-bar, and similar UI elements may slightly increase your startup time.
To customize your Emacs setup to include various user interface elements, you can use the following settings in your ~/.emacs.d/pre-early-init.el:
(setq minimal-emacs-ui-features '(context-menu tool-bar menu-bar dialogs tooltips))These settings control the visibility of dialogs, context menus, toolbars, menu bars, and tooltips.
Emacs, by default, stores various configuration files, caches, backups, and other data in the ~/.emacs.d directory. Over time, this directory can become cluttered with numerous files, making it difficult to manage and maintain.
One common solution to this issue is the installation of the no-littering package, which reduces clutter in the ~/.emacs.d directory.
However, an alternative lightweight approach is to simply change the default ~/.emacs.d directory to ~/.emacs.d/var/, which will contain all the files that Emacs typically stores in the base directory. This can be accomplished by adding the following code to ~/.emacs.d/pre-early-init.el:
;; Reducing clutter in ~/.emacs.d by redirecting files to ~/emacs.d/var/
(setq minimal-emacs-var-dir (expand-file-name "var/" minimal-emacs-user-directory))
(setq package-user-dir (expand-file-name "elpa" minimal-emacs-var-dir))
(setq user-emacs-directory minimal-emacs-var-dir)
To prevent Emacs from saving customization information to a custom file, set custom-file to null-device:
(setq custom-file null-device)
The recentf, savehist, saveplace, and auto-revert built-in packages are already configured by minimal-emacs.d. All you need to do is activate them by adding the following to ~/.emacs.d/post-init.el:
;; Auto-revert in Emacs is a feature that automatically updates the
;; contents of a buffer to reflect changes made to the underlying file
;; on disk.
(add-hook 'after-init-hook #'global-auto-revert-mode)
;; recentf is an Emacs package that maintains a list of recently
;; accessed files, making it easier to reopen files you have worked on
;; recently.
(add-hook 'after-init-hook #'recentf-mode)
;; savehist is an Emacs feature that preserves the minibuffer history between
;; sessions. It saves the history of inputs in the minibuffer, such as commands,
;; search strings, and other prompts, to a file. This allows users to retain
;; their minibuffer history across Emacs restarts.
(add-hook 'after-init-hook #'savehist-mode)
;; save-place-mode enables Emacs to remember the last location within a file
;; upon reopening. This feature is particularly beneficial for resuming work at
;; the precise point where you previously left off.
(add-hook 'after-init-hook #'save-place-mode)Check if native compilation is enabled by evaluating (native-comp-available-p) in Emacs. If the result is non-nil, it indicates that native compilation is active.
Native compilation can greatly enhance performance by translating Emacs Lisp code into native machine code, leading to faster execution and improved responsiveness.
The emacs-libvterm package is a terminal emulator integrated into GNU Emacs. Built on libvterm, a C library, it offers superior performance compared to Elisp-based alternatives. This compiled code approach enables emacs-libvterm to handle large outputs efficiently, providing a fast and feature-complete terminal experience within Emacs.
To configure emacs-vterm, add the following to ~/.emacs.d/post-init.el:
(use-package vterm
:ensure t
:defer t
:commands vterm
:config
;; Speed up vterm
(setq vterm-timer-delay 0.01))(Note that the emacs-vterm Emacs package requires compilation of its C components, which includes the gcc compiler and the libvterm library. On Debian or Ubuntu systems, the necessary packages can be installed with: sudo apt-get install build-essential libvterm-dev libtool-bin cmake)
Vertico, Consult, and Embark collectively enhance Emacs' completion and navigation capabilities. Vertico provides a vertical completion interface, making it easier to navigate and select from completion candidates (e.g., when M-x is pressed). Consult offers a suite of commands for efficient searching, previewing, and interacting with buffers, file contents, and more, improving various tasks. Embark integrates with these tools to provide context-sensitive actions and quick access to commands based on the current selection, further improving user efficiency and workflow within Emacs. Together, they create a cohesive and powerful environment for managing completions and interactions.
Add the following to ~/.emacs.d/post-init.el to set up Vertico, Consult, and Embark:
;; Tip: You can remove the `vertico-mode' use-package and replace it
;; with the built-in `fido-vertical-mode'.
(use-package vertico
;; (Note: It is recommended to also enable the savehist package.)
:ensure t

;; evil-want-keybinding must be declared before Evil and Evil Collection
(setq evil-want-keybinding nil)
(use-package evil
:ensure t
:init
(setq evil-undo-system 'undo-fu)

:commands (undo-fu-only-undo
undo-fu-only-redo
undo-fu-only-redo-all
undo-fu-disable-checkpoint)
:custom
;; 3 times the default values

(undo-strong-limit (* 3 240000)))
(use-package undo-fu-session
:ensure t
:config
(undo-fu-session-global-mode))
You can also use the vim-tab-bar Emacs package to ~/.emacs.d/post-init.el to give the built-in Emacs tab-bar a style similar to Vim's tabbed browsing interface:
(use-package vim-tab-bar
:ensure t
:commands vim-tab-bar-mode
:hook (after-init . vim-tab-bar-mode))You can also add vdiff, a package that provides Vimdiff-like functionality to Emacs:
(use-package vdiff
:ensure t
:defer t
:commands (vdiff-buffers
vdiff-buffers3
vdiff-quit
vdiff-files
vdiff-files3)
:custom
(vdiff-auto-refine t)
(vdiff-only-highlight-refinements t))The evil-visualstar package allows using * or # search from the visual selection:
(use-package evil-visualstar
:after evil
:ensure t
:defer t
:commands global-evil-visualstar-mode
:hook (after-init . global-evil-visualstar-mode))The evil-surround package simplifies handling surrounding characters, such as parentheses, brackets, quotes, etc. It provides key bindings to easily add, change, or delete these surrounding characters in pairs. For instance, you can surround the currently selected text with double quotes in visual state using S" or gS":
(use-package evil-surround
:after evil
:ensure t
:defer t
:commands global-evil-surround-mode
:custom
(evil-surround-pairs-alist
'((?\( . ("(" . ")"))
(?\[ . ("[" . "]"))
(?\{ . ("{" . "}"))
(?\) . ("(" . ")"))
(?\] . ("[" . "]"))
(?\} . ("{" . "}"))
(?< . ("<" . ">"))
(?> . ("<" . ">"))))
:hook (after-init . global-evil-surround-mode))You can also add the following code to enable commenting and uncommenting by pressing gcc in normal mode and gc in visual mode (thanks you to the Reddit user u/mistakenuser for this contribution, which replaces the evil-commentary package):
(with-eval-after-load "evil"
(evil-define-operator my-evil-comment-or-uncomment (beg end)
"Toggle comment for the region between BEG and END."
(interactive "<r>")
(comment-or-uncomment-region beg end))
(evil-define-key 'normal 'global (kbd "gc") 'my-evil-comment-or-uncomment))Evil-snipe provides 2-character motions for quickly jumping around text compared to Evil's built-in f/F/t/T motions, incrementally highlighting candidate targets as you type. By default, snipe only binds s (forward) and S (backward) to evil-snipe-s and evil-snipe-S, respectively. In operator mode, snipe is bound to z/Z and x/X (exclusive):
(use-package evil-snipe
:defer t
:commands evil-snipe-mode
:hook (after-init . evil-snipe-mode))To set up Language Server Protocol (LSP) servers using Eglot, you can configure it in your Emacs setup as follows. This configuration ensures minimal disruption from Eglot’s progress reporting and optimizes performance by disabling unnecessary logging.
To configure eglot, add the following to ~/.emacs.d/post-init.el:
(use-package eglot
:ensure nil
:defer t
:commands (eglot
eglot-rename
eglot-ensure
eglot-rename
eglot-format-buffer)
:custom
(eglot-report-progress nil) ; Prevent minibuffer spam
:config
;; Optimizations
(fset #'jsonrpc--log-event #'ignore)
(setq jsonrpc-event-hook nil))Here is an example of how to configure Eglot to enable or disable certain options for the pylsp server in Python development. (Note that a third-party tool, python-lsp-server, must be installed):
(setq-default eglot-workspace-configuration

(add-hook 'python-mode-hook #'eglot)
(add-hook 'python-ts-mode-hook #'eglot)Corfu enhances in-buffer completion by displaying a compact popup with current candidates, positioned either below or above the point. Candidates can be selected by navigating up or down.
Cape, or Completion At Point Extensions, extends the capabilities of in-buffer completion. It integrates with Corfu or the default completion UI, by providing additional backends through completion-at-point-functions.
To configure corfu and cape, add the following to ~/.emacs.d/post-init.el:
(use-package corfu

Add the following to ~/.emacs.d/pre-early-init.el to ensure that minimal-emacs.d restores the specified amount after startup:
(setq minimal-emacs-gc-cons-threshold (* 64 1024 1024))If you want to to change the outline-mode or outline-minor-mode Ellipsis (...) to (▼), use the code snippet in this article: Changing the Ellipsis (“…”) in outline-mode and outline-minor-mode.
Add the following to the top of the ~/.emacs.d/pre-early-init.el file to make minimal-emacs.d use the MINIMAL_EMACS_USER_DIRECTORY environment variable to change ~/.emacs.d to another directory:
;; Place this at the very beginning of pre-early-init.el
(let ((previous-minimal-emacs-user-directory (expand-file-name
minimal-emacs-user-directory))
(env-dir (getenv "MINIMAL_EMACS_USER_DIRECTORY")))
(setq minimal-emacs-user-directory (if env-dir
(expand-file-name env-dir)
(expand-file-name user-emacs-directory)))
(unless (string= minimal-emacs-user-directory
previous-minimal-emacs-user-directory)
;; Load pre-early-init.el from the new directory
(minimal-emacs-load-user-init "pre-early-init.el")))During the execution of early-init.el (and pre-early-init.el and post-early-init.el), Emacs has not yet loaded the graphical user interface (GUI). This file is used for configurations that need to be applied before the GUI is initialized, such as settings that affect the early stages of the Emacs startup process.
Thus, post-early-init.el and pre-init.el serve different purposes and are not the same.
The menu bar is disabled by default in minimal-emacs.d to provide a minimal, distraction-free environment, which many experienced users prefer.
The menu bar can be re-enabled by adding the following configuration to ~/.emacs.d/pre-early-init.el:
(setq minimal-emacs-ui-features '(menu-bar))
Other UI features can also be enabled by adding the following to ~/.emacs.d/pre-early-init.el:
(setq minimal-emacs-ui-features '(context-menu tool-bar menu-bar dialogs tooltips))
The author began working on it after realizing that no existing starter kit offered a truly minimal setup with the flexibility for users to choose exactly what to include in their configuration.
To ensure the minimal-emacs.d configuration loads post-early-init.el, pre-init.el, and post-init.el from a different directory, such as ~/.config/minimal-emacs.d/, modify the minimal-emacs-user-directory variable by adding the following to your ~/.emacs.d/pre-early-init.el file:
(setq minimal-emacs-user-directory "~/.config/minimal-emacs.d/")This will ensure that the minimal-emacs.d configuration loads post-early-init.el, pre-init.el, and post-init.el from ~/.config/minimal-emacs.d/.
