Install Doom alongside other configs (with Chemacs2)

Chemacs2 is a bootloader for Emacs. It allows you to switch between multiple Emacs configurations. Here is a quick guide for setting it up with Doom Emacs as the default config:

1. First, install Doom somewhere:

   git clone https://github.com/hlissner/doom-emacs ~/doom-emacs
   ~/doom-emacs/bin/doom install
       

2. Move aside any existing config and install Chemacs2 as your new ~/.emacs.d:

   [ -f ~/.emacs ] && mv ~/.emacs ~/.emacs.bak
   [ -d ~/.emacs.d ] && mv ~/.emacs.d ~/.emacs.legacy
   git clone https://github.com/plexus/chemacs2.git ~/.emacs.d
       

3. Create ~/.emacs-profiles.el with a list of your Emacs profiles. This file is structured like a .dir-locals.el file. Here is an example with Doom (as the default), Spacemacs, and Prelude:

   (("default"   . ((user-emacs-directory . "~/doom-emacs")))
    ("legacy" . ((user-emacs-directory . "~/.emacs.legacy")))
    ("spacemacs"   . ((user-emacs-directory . "~/spacemacs"))))
       

To start Emacs with a specific config, use the --with-profile option:

emacs --with-profile spacemacs
