saber-overlay

Overlay containing Nix packages used within the Saber ecosystem.

Usage

Nix flakes (recommended)

The following helper exports several packages:

• env-anchor-idls - environment which allows the use of the anchor idl command
• env-anchor-build - exposes tools to create verifiable Anchor builds
• rust - exposes Cargo/Rustc as used in CI

To use these in GitHub Actions, you may reference the Saber Periphery GitHub actions and pick one of the below flake formats:

{
  description = "My development environment.";

  inputs = {
    saber-overlay.url = "github:saber-hq/saber-overlay";
  };

  outputs = { self, saber-overlay }: saber-overlay.lib.defaultFlakeOutputs;
}

Locking a specific Anchor/Solana version

{
  description = "My development environment.";

  inputs = {
    saber-overlay.url = "github:saber-hq/saber-overlay";
  };

  outputs = { self, saber-overlay }: saber-overlay.lib.buildFlakeOutputs {
    setupBuildTools = { pkgs }: {
      solana = pkgs.solana-1_9;
      anchor = pkgs.anchor-0_23_0;
    };
  };
}

Overlay

let
    saberOverlay = fetchFromGitHub {
        owner = "saber-hq";
        repo = "saber-overlay";
        rev = "master";
        sha256 = "...";
    };
    nixpkgs = import <nixpkgs> { overlays = [ (import saberOverlay) ]; };
in
    with nixpkgs;
