Installation
------------

1. Install the build dependencies for Emacs:

$ sudo apt build-dep emacs
$ sudo apt install libtree-sitter-dev

2. Download and unpack the Emacs archive:

$ wget http://mirrors.nav.ro/gnu/emacs/emacs-29.1.tar.xz
$ tar xvf emacs-29.1.tar.xz

3. Install Emacs in HOME/.local/emacs/:

$ ./autogen.sh
$ ./configure --prefix="$HOME/.local/emacs/" --without-compress-install --with-native-compilation --with-json --with-mailutils --with-tree-sitter CC=gcc-12
$ make -j 4   # Replace the number 4 with the number of cores that your CPU has.
$ make install

NOTE: If you're using Wayland, you might want to consider compiling Emacs 29 with the '--with-pgtk' option as well.

Uninstallation
