# 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. `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.
