I rely on quite a few extensions that have been made available on various ELPA repositories. Recently, I have moved to installing and managing Emacs packages like any other software package on my system with the functional package manager [[https://gnu.org/s/guix][GNU Guix]]. I find this more reliable, although at first it is slightly less convenient as I can no longer just use =package.el= but first need to package the Elisp code for Guix. |
