modular-config.el VS chemacs2

Thanks everyone for the helpful replies! I think I'll mainly use the method 7890yuiop and jackson15j mentioned, involving putting a common configuration in .emacs.d and using .emacs for things specific to the machine. modular-config also looks quite nice.

I am the maintainer of modular-config.el. I created this package out of my own necessity for dividing my emacs configuration file into multiple files. At this moment, I am feeling the need to make it more robust and optimized.

You could manage such a system with tools like Chemacs, https://github.com/plexus/chemacs2

Edit: Actually this may be what you want: https://github.com/plexus/chemacs2

https://www.spacemacs.org/ is a layer on top of emacs that solves a number of shortcomings including a more modern UI. If you use https://github.com/plexus/chemacs2, you can always run emacs and spacemacs independently, both for learning, troubleshooting etc.

have a look at how https://github.com/plexus/chemacs2 does this sort of things.

I asked this same question a year and half ago and since that post I started reading Mastering Emacs by Mickey Petersen which was really helpful, I used Chemacs to keep my evil config around in case I give up. But I ended up dropping that config and I realized I wasn't really into modal editing. It took me one month to get used to my new config but that was worth it, everything in Emacs became consistent.

Perhaps the biggest game changer in my new init file is chemacs2. This allows one to choose one among many possible ".emacs.d" directories to use for the emacs that is being invoked.
