-# Pinch
-
-PIN CHannels - a simple drop-in replacement for `nix-channel --update`.
-
-Example usage, being invoked on the example "channels" file included here:
-
- $ python3 pinch.py pin channels
- $ python3 pinch.py update channels
-
-
-The first "pin" command will add these fields to the file:
-
- [nixos]
- channel_url = https://channels.nixos.org/nixos-20.03
- git_repo = https://github.com/NixOS/nixpkgs.git
- git_ref = nixos-20.03
- +release_name = nixos-20.03beta1155.29eddfc36d7
- +tarball_url = https://releases.nixos.org/nixos/20.03/nixos-20.03beta1155.29eddfc36d7/nixexprs.tar.xz
- +tarball_sha256 = 9c1d182af2af64e5e8799e256a4a6dc1fed324ba06cb5f76c938dc63b64f0959
- +git_revision = 29eddfc36d720dcc4822581175217543b387b1e8
-
- [nixos-hardware]
- git_repo = https://github.com/NixOS/nixos-hardware.git
- git_ref = master
- +release_name = nixos-hardware.git-1585241157-edb7199b5c4
- +git_revision = edb7199b5c4f1db34a7253d4cabf6cf690521a92
-
-The second "update" command applies these changes to your nix channels, like `nix-channel --update` does.
