PackageGenerator

A tool to generate Package.swift files using a custom DSL allowing version alignment of dependencies across packages.

Usage

PackageGenerator uses ArgumentParser and Stencil.

The command generate-package requires the following arguments:

• path: Path to the folder containing the packages.
• template-path: Path to the Stencil template.
• dependencies-path: Path to the RemoteDependencies.json file.

RemoteDependencies.json should contain the list of remote dependencies used by your packages. E.g.

{
    "dependencies": [
        {
            "name": "Alamofire",
            "url": "https://github.com/Alamofire/Alamofire",
            "version": "5.6.1"
        },
        {
            "name": "ViewInspector",
            "url": "https://github.com/nalexn/ViewInspector",
            "version": "0.9.2"
        }
    ]
}

Packages should be contained in respective folders inside a packages folder and provide a <package_name>.json spec. E.g.

{
  "name": "Example",
  "products": [
    {
      "name": "Example",
      "productType": "library",
      "targets": [
        "ExampleTarget"
      ]
    }
  ],
  "localDependencies": [
    {
      "name": "ExampleLocalDependency",
      "path": "../LocalDependencies"
    }
  ],
  "remoteDependencies": [
    {
      "name": "Alamofire"
    },
    {
      "name": "ViewInspector",
      "version": "1.2.3"
    },
  ],
  "targets": [
    {
      "name": "ExampleTarget",
      "targetType": "target",
      "dependencies": [
        {
          "name": "Alamofire"
        }
      ],
      "sourcesPath": "Framework/Sources",
      "resourcesPath": "Resources"
    },
    {
      "name": "ExampleTargetTests",
      "targetType": "testTarget",
      "dependencies": [
        {
          "name": "ExampleTarget",
          "isTarget": true
        },
        {
          "name": "ViewInspector"
        }
      ],
      "sourcesPath": "Tests/Sources",
      "resourcesPath": "Resources"
    }
  ]
}

Note that PackageGenerator will automatically retrieve url & version values for remoteDependencies from the RemoteDependencies.json file. If you need to override those values, you can set them in the package spec.

We provide a default Stencil template that PackageGenerator can work with.

The command generate-packages allows you to generate Package.swift files from a given folder of packages. It takes the same arguments as generate-package along with packages-folder-path. PackageGenerator will loop though subfolders and generate Package.swift files from JSON specs.

Ideally, you want to generate a PackageGenerator executable and automate tasks both locally and on CI.

Demo

In the PackageGenerator scheme, enable 'Use custom working directory' and set the value to the folder containing the PackageGenerator package. The scheme has arguments set to showcase the creation of a Package.swift file using some provided files.

When running the default scheme you should see a Package.swift file being generated in the Packages/Example/ folder.
