derui’s Emacs Configurations

My emacs configuration since 2013.

Features

• Aims for a fast launch time, achieving approximately 150ms.
• Provide wide range packages for usability.
  • Writing, development, and more. But I don’t use Emacs as for all , so this config do not contain email client, slack client, and some 3rd party clients.
• Strive for maximum replicability using elpaca.
• Optimized for early Emacs versions (e.g., 31.0.50 for daily use).
• Includes support for Japanese input methods.
• This configuration can run on Linux and macOS.
  • I’m living Linux for daily, but I’m working on macOS.

Install

Clone this repository to $XDG_CONFIG_DIR//emacs . This repository keeps as clean as possible user’s emacs directory. Use $XDG_CONFIG_DIR/emacs-local for user-related state and configurations.

Configuration

My config will load user-env.el on early stage of launching. It is the best place to set some options.

Develop

You need Taskfile to build init.el/early-init.el in your environment.

$ mkdir -p ~/.config/
$ git clone https://github.com/derui/dot.emacs.d ~/.config/emacs
$ cd ~/.config/emacs
# Tangle early-init.el and init.el.
$ task tangle

Notice, I’ve decided to not to compile init.el . It is not recommended by official document, but it is only used to launch time. Some macros defined in init.el are tiny and simple, so no worry about that.

Update dependencies

If you want to update dependencies, follow these instructions:

1. update dependencies under $XDG_CONFIG_DIR/emacs-local/elpaca/repos . You can use method that you like, elpaca-update or just pull main of the package.
2. My taskfile contains the command update-lock to update elpaca’s lock file, just run task update-lock
3. It will launch new Emacs. After you finish updating elpaca, just execute my/write-elpaca-lock .
4. After that, you get update elpaca.lock. Commit it.
