# Updating

To update the list of packages from MELPA,

1. Clone https://github.com/ttuegel/emacs2nix.
2. Clone https://github.com/milkypostman/melpa.
3. Run `./melpa-packages.sh --melpa PATH_TO_MELPA_CLONE` from emacs2nix.
4. Copy the new `melpa-generated.nix` file into Nixpkgs.
5. Check for evaluation errors: `nix-instantiate ./. -A emacsPackagesNg.melpaPackages`.
6. `git add pkgs/applications/editors/emacs-modes/melpa-generated.nix && git commit -m "melpa-packages $(date -Idate)"`
