# Updating

To update the list of packages from MELPA,

1. Run `./update-elpa`.
2. Check for evaluation errors:
     env NIXPKGS_ALLOW_BROKEN=1 nix-instantiate ../../../../../ -A emacs.pkgs.elpaPackages
3. Run `git commit -m "elpa-packages $(date -Idate)" -- elpa-generated.nix`

## Update from overlay

Alternatively, run the following command:

./update-from-overlay

It will update both melpa and elpa packages using
https://github.com/nix-community/emacs-overlay. It's almost instantenous and
formats commits for you.
