What this config does?

1. Use melpa only.
2. Use emacs version 30.1.
3. Use Maple Mono NF CN (NO Ligature!): repo, download.
4. Use Plantuml for uml drawing: download.
5. Use emacs build-in tree-sitter.

Getting started

Ubuntu:

curl -sSL https://gist.githubusercontent.com/Jamie-Cui/e0c613bad06e17f34be591efb7615896/raw/00e86159e15191698f038d2be4367358f46fa66c/install-emacs-and-deps.sh | bash

Prerequisite

• gcc toolchain (gcc, g++, cmake, makefile, autotools, …): compile environment
• libgccjit: for emacs’s native compilation feature
• libsqlite3: for org-roam database
• libtree-sitter (tested with version 0.25.8, repo): for tree-sitter,
• (optional) texlive: for latex
• (optional) direnv: for separating project envs (sudo dnf install direnv)

# macos, if you have not done so, in ~/.zshrc
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/homebrew/lib/
# why tree-sitter@0.25? see: https://github.com/jdtsmith/emacs-mac/issues/121
brew install autoconf texinfo libgccjit gcc gnutls tree-sitter@0.25 pkg-config coreutils

Download and Compile Emacs

# download
wget -c https://github.com/emacs-mirror/emacs/archive/refs/tags/emacs-30.1.tar.gz
# or the following dev branch with tty-child-frame feature
wget -c https://github.com/emacs-mirror/emacs/archive/refs/heads/scratch/tty-child-frames.zip

# unzip and enter emacs folder
./autogen.sh
# (alt) configure terminal emacs
./configure --with-native-compilation --with-tree-sitter --with-gnutls --without-x-toolkit --without-xpm --without-gif --without-tiff --with-sqlite3
# (alt) configure gui emacs
./configure --with-native-compilation --with-tree-sitter --with-sqlite3 --with-rsvg --without-x-toolkit
# compile
sudo make install

MacOS: libgccjit failed to compile and run? see: d12frosted/homebrew-emacs-plus#680 (comment)

Have tree-sitter problem? see: link. Or download tree-sitter pre-built binaries here.

Setup $HOME/.emacs.d/init.el

(defvar +emacs/repo-directory "~/Desktop/emacs.d")
(load (concat +emacs/repo-directory "/init.el"))
