Nix flake for the Digital Asset Package Manager (dpm) - the official CLI tool for the DAML SDK.

dpm is a drop-in replacement for the now-deprecated daml assistant. It provides commands for:

• Building DAML projects: dpm build
• Running tests: dpm test
• Code generation: dpm codegen-java, dpm codegen-js, dpm codegen-alpha-typescript
• Running sandbox: dpm sandbox
• Managing SDK versions: dpm install, dpm version
• And more: dpm studio, dpm new, dpm docs, etc.

Add this flake to your flake.nix inputs:

{
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
    nix-dpm.url = "github:0xsend/nix-dpm";  # Update with actual repo
  };

  outputs = { self, nixpkgs, nix-dpm, ... }:
    let
      system = "aarch64-darwin";  # or your system
      pkgs = import nixpkgs {
        inherit system;
        overlays = [ nix-dpm.overlays.default ];
      };
    in
    {
      devShells.${system}.default = pkgs.mkShell {
        packages = [ pkgs.dpm ];
      };
    };
}

{
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
    nix-dpm.url = "github:0xsend/nix-dpm";  # Update with actual repo
  };

  outputs = { self, nixpkgs, nix-dpm, ... }:
    let
      system = "aarch64-darwin";
      pkgs = nixpkgs.legacyPackages.${system};
    in
    {
      devShells.${system}.default = pkgs.mkShell {
        packages = [ nix-dpm.packages.${system}.default ];
      };
    };
}

nix run github:0xsend/nix-dpm -- build
nix run github:0xsend/nix-dpm -- test

nix develop github:0xsend/nix-dpm

This repository automatically checks for new dpm releases daily via GitHub Actions. When a new version is detected:

1. Check: Fetches latest version from Digital Asset
2. Hash: Downloads all platform tarballs and computes SHA256 hashes
3. Verify: Builds and tests on all 4 platforms (Linux x86_64, Linux ARM64, macOS x86_64, macOS ARM64)
4. Commit: Auto-commits the update if all builds pass

You can also manually trigger an update via the GitHub Actions UI.

Digital Asset does not currently provide GPG signatures or published checksums for dpm releases. The security model relies on:

Once hashes are committed, Nix's content-addressed store ensures you always get the exact same binary.

To manually update to a new version:

./scripts/update-version.sh           # Latest version
./scripts/update-version.sh 3.4.10    # Specific version

Or manually:

1. Get the latest version:

   curl -sS https://get.digitalasset.com/install/latest

2. Run the update script or manually compute hashes:

   VERSION="X.Y.Z"
   for PLATFORM in darwin-arm64 darwin-amd64 linux-amd64 linux-arm64; do
     TARBALL="dpm-${VERSION}-${PLATFORM}.tar.gz"
     URL="https://artifactregistry.googleapis.com/download/v1/projects/da-images/locations/europe/repositories/public-generic/files/dpm-sdk:${VERSION}:${TARBALL}:download?alt=media"
     echo "${PLATFORM}:"
     curl -SLf "${URL}" | shasum -a 256
   done

3. Update dpm-sources.json with the new version and hashes

4. Test the build:

   nix build .#dpm
   ./result/bin/dpm version
