MinEmacs (NG)

MinEmacs is a complete and fast Emacs configuration framework.

Why?

Long story short, I'm relaying on Emacs for my everyday's work, so I needed a fast and stable configuration that fits my needs. MinEmacs is changing constantly, please refer to the change log for more information. See also the list of MinEmacs' modules and packages.

Note

Please note that I have no intent or availability to create an alternative to Doom Emacs or Spacemacs. While I find joy (like every other Emacser out there) in tinkering with Emacs, MinEmacs remains just a tool that I use in my everyday work, and that I like to share with other Emacsers.

Main features

MinEmacs comes with batteries included. Here are some of its unique features:

Laziness

Defer loading packages until the user needs them. Or, for packages that needs to be loaded, try to do that after starting Emacs.

Modules system

The packages are grouped in modules, with a bit of glue to make them work together.

On demand modules

MinEmacs includes a large number of major-modes and packages to work with programming languages. However, the majority of these packages aren't loaded at startup. MinEmacs uses an on-demand system to load the packages only when the user opens a supported file, or when he opens a buffer with a mode that can be extended by one of the on-demand modules. The behavior of this feature customized via minemacs-on-demand-enable-auto-mode, minemacs-on-demand-enable-magic-mode, minemacs-on-demand-enable-interpreter-mode and minemacs-on-demand-enable-companion-packages.

Install

Open a shell and run:

git clone --recursive https://github.com/abougouffa/minemacs.git ~/.emacs.d && emacs

By executing this command, the repository will be cloned, and Emacs will be launched. During the initial run, Emacs will automatically install the necessary packages. You might need to run M-x minemacs-run-build-functions when Emacs loads up to install some extra stuff (build some libraries, install Nerd Fonts, etc.)

Important

Please note that I'm using a fresh Emacs 29.4.50 (recommended version) built from the emacs-29 branch mainly on two machines, one based on Manjaro Linux and the other on (the quite old) Debian 10. However, I have set up some basic Github CI actions that automatically test running this configuration on Emacs 29 and 30 in Ubuntu Linux and MacOS and on Emacs 29 in Windows. These actions ensure that MinEmacs is "runnable" on these systems; with all its modules enabled. However, more testing should be done to validate the configuration as a whole on systems other than Linux.

Customization

To personalize MinEmacs, you can add a specific set of files within the default user configuration directory, which is located by default at ~/.minemacs.d/ or .emacs.d/user-config/ (the first to be found). However, if you prefer to use a different directory, you have the flexibility to do so by setting the MINEMACSDIR environment variable.

Main configuration files

There are two main files that can be added in the ~/.minemacs.d directory:

1. The ~/.minemacs.d/modules.el file contains a list of enabled modules and/or a list of disabled packages (minemacs-modules and minemacs-disabled-packages can be set in this file). So if you want to enable a module (ex. me-prog) but you need to exclude a particular package (ex. ts-movement), you can add the latter to minemacs-disabled-packages.
2. The ~/.minemacs.d/config.el file contains the user configuration and customization, you can think of it as your init.el, which gets loaded at the end of MinEmacs' init.el!

This repository contains skeleton files for modules.el and config.el (under skel/). We highly recommend following the same structure as in the skeleton files, specially the use of with-eval-after-load and use-package instead of using require directly (require loads the packages immediately, which increases the startup time of Emacs).

Machine-specific configuration files

In my workflow, I use mainly the same configuration files across all my machines (which, following the tradition, are shared in my dotfiles repository). However, I have some machine-specific (local) configurations that contain some private and machine-specific configurations. For example, I use them to overwrite the email address on my workstation, to setup my Email accounts, to setup Forge and Jira integration in my workstation, and so on.

For this purpose, MinEmacs will also check for files in ~/.minemacs.d/local/{early-config,init-tweaks,modules,config}.el and load them, after the ~/.minemacs.d/{early-config,init-tweaks,modules,config}.el if they exists.

Advanced configuration files

MinEmacs provides also some advanced customization files, these files can be used to tweak MinEmacs' behavior, add some early initialization code, make MinEmacs runnable on older Emacs versions, etc.

1. The ~/.minemacs.d/early-config.el file is loaded at the end of MinEmacs' early-init.el. You can use it to set up some early stuff like tweaking the UI, overwrite the variables set by MinEmacs in ~/.emacs.d/early-init.el, and so on.
2. The ~/.minemacs.d/init-tweaks.el file is loaded at an early stage of the init.el file. You can use it to do some useful stuff before MinEmacs starts to customize packages and load modules. See the comments in init.el for more information.

Environment variables

You can customize MinEmacs' behavior via some environment variables.

• MINEMACS_DIR or MINEMACSDIR: Path for MinEmacs user configuration directory, if not set, ~/.minemacs.d/ is used.
• MINEMACS_MSG_LEVEL: Change message log level, from 1 (only errors) to 4 (all messages).
• MINEMACS_VERBOSE: Be more verbose (useful for debugging).
• MINEMACS_DEBUG: Enable debugging at startup (and be verbose).
• MINEMACS_ALPHA: Set frame background-alpha to percentage (value from 0 to 100).
• MINEMACS_NOT_LAZY: Load lazy packages immediately after loading Emacs.
• MINEMACS_ALWAYS_DEMAND: Load all packages immediately (this works by setting use-package-always-demand to t and use-package-always-defer to nil (by default, MinEmacs sets use-package to always defer, unless explicit :demand is added).
• MINEMACS_IGNORE_USER_CONFIG: space-separated values, used to disables loading ~/.minemacs.d/<file>.el user configuration files. Accepted values for <file> are: early-config, init-tweaks, modules, config, local/early-config, local/init-tweaks, local/modules and local/config. Use all to disable all user configuration files.
• MINEMACS_LOAD_ALL_MODULES: Load all modules (without taking ~/.minemacs.d/modules.el into account).
• MINEMACS_BENCHMARK: Run a benchmark at initialization of Emacs (using benchmark-init.el) and display the results after startup (including lazy packages).
• MINEMACS_NO_PROXIES: Set if you have minemacs-proxies setup in your early-config.el but you want to start Emacs without passing by these proxies (useful if you use some proxies for workplace but you want Emacs to start without passing by them to be able to download packages).
