||
**MinEmacs** is a lightweight Emacs configuration framework. | ||

||
## Why? | ||
I was using Doom Emacs, which I initially considered to be a remarkable software | ||
that introduced me to the world of Emacs. Nonetheless, my experience with it | ||
turned out to be **less enjoyable** later. | ||
|
||
Emacs forms the foundation of my workflow, serving as my go-to tool for various | ||
tasks such as document writing, academic paper writing, programming in multiple | ||
languages, email management, and staying updated with news, among other things. | ||
|
||
Hence, I wanted a framework that is both robust and straightforward. Doom Emacs | ||
seemed like a suitable choice initially. However, before I started this project | ||
back in September 2022, I encountered numerous issues with Doom Emacs. | ||
Occasionally, after running the `doom upgrade` command, everything would cease to | ||
function properly. These problems always seemed to arise during my busiest days, | ||
causing unnecessary additional stress. To be frank, at that time, Doom Emacs | ||
started to feel overly complex as a configuration framework. It incorporated a | ||
command line interface, an extensive library with extra features, numerous | ||
unnecessary hacks to tweak Emacs behavior for a negligible improvement in | ||
startup time, configuration modules that tightly combined various packages in an | ||
opinionated manner, CI commands, and even a profile manager! Each of these | ||
features introduced extra complexity and more failure points at every layer. | ||
|
||
As a result, MinEmacs emerged as my personal configuration framework for Emacs, | ||
*and it continues to serve that purpose*. I'm trying to tailor it to my specific | ||
needs while maintaining its modularity and portability. However, I have no | ||
intention 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. However, please note that I am not really interested | ||
in becoming a full-time maintainer of this tool that I would only use to | ||
maintain itself! | ||
|
||
## Install | ||
Open a shell and run: | ||
|
||
```shell | ||
git clone 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. | ||
|
||
> [!IMPORTANT] | ||
> Please note that I'm using a fresh Emacs 29 built from source on a Manjaro | ||
> Linux system. I have enabled basic [Github CI | ||
> actions](https://github.com/abougouffa/minemacs/actions) to automatically test | ||
> running Emacs on [Ubuntu Linux (Emacs 28 and | ||
> 29)](https://github.com/abougouffa/minemacs/actions/workflows/ci-linux.yaml), | ||
> [MacOS (Emacs | ||
> 29)](https://github.com/abougouffa/minemacs/actions/workflows/ci-macos.yaml) | ||
> and [Windows (Emacs | ||
> 28)](https://github.com/abougouffa/minemacs/actions/workflows/ci-windows.yaml). | ||
> These actions ensure that MinEmacs is "runnable"; with all modules enabled on | ||
> these systems. However, more testing should be done to validate the | ||
> configuration on systems other than Linux. | ||
> | ||
> I'm trying to support at least Emacs 28.2, so [I back port some of the new | ||
> functions/macros I use to Emacs 28](core/me-backports-29.el). Furthermore, for | ||
> Emacs 28 and earlier, MinEmacs includes the `me-compat` module which loads the | ||
> `compat` package at early stage (just after bootstrapping `straight` and | ||
> `use-package`), this can facilitate porting MinEmacs to earlier Emacs | ||
> versions. However, I've never tested MinEmacs with versions earlier than 28.2, | ||
> and I don't plan to do so! | ||
## Customization | ||
To personalize MinEmacs, you can incorporate a specific set of files within the | ||
default user configuration directory, which is located at `~/.minemacs.d`. | ||
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 a | ||
list of disabled packages (`minemacs-core-modules`, `minemacs-modules` and | ||
`minemacs-disabled-packages` can be set in this file). | ||
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](skel/modules.el) and | ||
[config.el](skel/config.el) (under [skel/](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). | ||
|
||
### 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, 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. This can be useful for porting | ||
MinEmacs to an older Emacs version by providing an implementation of new | ||
functions MinEmacs uses. See the [init.el](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. | ||
- `MINEMACS_ALPHA`: Set frame `background-alpha` to percentage (value from 0 to | ||
100). | ||
- `MINEMACS_NOT_LAZY`: Load lazy packages immediately after loading Emacs. | ||
- `MINEMACS_IGNORE_VERSION_CHECK`: Do not perform version check in `init.el`, | ||
this can be useful if you use `~/.minemacs.d/init-tweaks.el` to implement the | ||
functionalities used by MinEmacs and missing from your Emacs version. | ||
- `MINEMACS_IGNORE_CONFIG_EL`, `MINEMACS_IGNORE_MODULES_EL`, | ||
`MINEMACS_IGNORE_EARLY_CONFIG_EL` and `MINEMACS_IGNORE_INIT_TWEAKS_EL`: Ignore | ||
loading, respectively, the user configuration files `~/.minemacs.d/config.el`, | ||
`~/.minemacs.d/modules.el`, `~/.minemacs.d/early-config.el` et | ||
`~/.minemacs.d/init-tweaks.el`. | ||
- `MINEMACS_IGNORE_USER_CONFIG`: Ignore loading all user configuration files | ||
(present in `~/.minemacs.d`, or directory pointed by `$MINEMACSDIR`). | ||
|
||
