# Updating

To update the list of packages from MELPA,

1. Run `./update-melpa`
2. Check for evaluation errors:
     env NIXPKGS_ALLOW_BROKEN=1 nix-instantiate --show-trace ../../../../../ -A emacs.pkgs.melpaStablePackages
     env NIXPKGS_ALLOW_BROKEN=1 nix-instantiate --show-trace ../../../../../ -A emacs.pkgs.melpaPackages
3. Run `git commit -m "melpa-packages $(date -Idate)" recipes-archive-melpa.json`

## 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.
