1 | # Pinch |
| 2 | ||
| 3 | PIN CHannels - a simple drop-in replacement for `nix-channel --update`. | |
| 4 | ||
| 5 | Example usage, being invoked on the example "channels" file included here: | |
| 6 | ||
| 7 | $ python3 pinch.py pin channels | |
| 8 | $ python3 pinch.py update channels | |
| 9 | ||
| 10 | ||
| 11 | The first "pin" command will add these fields to the file: | |
| 12 | ||
| 13 | [nixos] | |
| 14 | channel_url = https://channels.nixos.org/nixos-20.03 | |
| 15 | git_repo = https://github.com/NixOS/nixpkgs.git | |
| 16 | git_ref = nixos-20.03 | |
| 17 | +release_name = nixos-20.03beta1155.29eddfc36d7 | |
| 18 | +tarball_url = https://releases.nixos.org/nixos/20.03/nixos-20.03beta1155.29eddfc36d7/nixexprs.tar.xz | |
| 19 | +tarball_sha256 = 9c1d182af2af64e5e8799e256a4a6dc1fed324ba06cb5f76c938dc63b64f0959 | |

| 22 | [nixos-hardware] | |
| 23 | git_repo = https://github.com/NixOS/nixos-hardware.git | |
| 24 | git_ref = master | |
| 25 | +release_name = nixos-hardware.git-1585241157-edb7199b5c4 | |

| 28 | The second "update" command applies these changes to your nix channels, like `nix-channel --update` does. | |
| 29 | ||
| 30 | Advantages over nix-channel: | |
| 31 | ||
| 32 | * Deploy the exact same channel content to multiple machines. | |
| 33 | * Store your pin file in revision control for more powerful rollback mechanism than `nix-channel --rollback`. | |
